The power output from the hydraulic continuously variable transmission 116 is transmitted to the mission case 118, and the mission case 118 has a rotational speed suitable for the traveling speed when traveling on the road or a rotational speed suitable for the traveling speed when planting seedlings. The gears are shifted and output to the front wheel 104 side or the rear wheel 105 side. Further, part of the power output from the mission case 118 is also transmitted to the seedling planting unit 150 side and used for planting work in the seedling planting unit 150.

  As described above, when the seedling transplanter 100 is operated, the speed change lever 135, the auxiliary speed change lever 138, and the like are operated to adjust the speed of the travel vehicle body 101 and to perform the operation or the work. . For example, when the shift lever 135 is operated, the gear ratio of the hydraulic continuously variable transmission 116 is switched according to the operation amount, and the output from the hydraulic continuously variable transmission 116 is changed. The sub transmission lever 138 can be switched to “working speed” or “road speed”, and the gear position of the sub transmission mechanism in the mission case 118 is the operation position of the sub transmission lever 138. It is switched by.

  When working in the field 350 using the seedling transplanter 100, the wheel enters the soil by the weight of the seedling transplanter 100. In particular, when working with the seedling transplanter 100, the work is performed in a state where water is applied to the field 350, so that the soil becomes soft and the wheels easily enter the soil. Thereby, the fertilizer concentration sensor 230 provided on the front wheel 104 also enters the lower end portion of the soil. The fertilizer concentration sensor 230 that has entered the soil detects the soil fertilizer concentration by detecting the energization resistance of the soil, and the detection result is transmitted to the controller 250. The controller 250 acquires the fertilizer concentration of soil by acquiring this detection result.

  In addition, when the seedling transplanter 100 performs the planting operation in the field 350, the GPS control device 220 acquires the position information of the seedling transplanter 100 while automatically performing the operation in the field 350 with the tractor 10. By performing steering with the steering device 210, it is possible to perform planting work while going straight ahead.

Get every.

  The tablet terminal device 300 stores information on a straight traveling route that is a traveling route for efficiently performing planting work in the farm field 350, and the controller 250 stores information on the straight traveling route stored in the tablet terminal device 300. The position information acquired by the receiving antenna 221 is compared, and the automatic steering device 210 is controlled.

  The control of the automatic steering device 210 is performed by detecting the steering angle with the handle potentiometer 212 so that the position information acquired by the receiving antenna 221 is in line with the straight traveling path information stored in the tablet terminal device 300. Steering is performed by operating the steering motor 211 while detecting a change in the traveling direction. Thereby, the traveling vehicle body 101 is caused to travel while being assisted along the straight traveling path stored in the tablet terminal device 300.

  When the seedling transplanter 100 is caused to run or work as described above, work information is stored in the tablet terminal device 300 by the tablet terminal device 300 as in the case of the work on the farm field 350 in the tractor 10. . In this tablet terminal device 300, map data of the farm field 350 to be operated can be stored and displayed on the touch panel 301. Further, based on previous work information or manually input data, Information can be displayed separately on a map. Thereby, in the tablet terminal device 300, based on the stored work information, a work plan for work to be performed can be performed. In the work plan, the field 350 where the work is performed, the work schedule, the contents of the work are determined, and the amount of work materials such as seedlings and fertilizer to be used is determined.

  Specifically, for the work information, the tablet terminal device 300 stores the work information of the seedling transplanter 100 that performs the work by communicating with the seedling transplanter 100 while being placed on the seedling transplanter 100. Is possible. This work information is related to, for example, work day, travel distance, work time, fuel consumption, planting work in the seedling planting unit 150, fertilization work in the fertilizer application 170, and supply of medicine in the medicine supply apparatus 201. Information and the like are stored. That is, in the tablet terminal device 300, not only the information regarding the operation state of the working device but also the set values such as the seedling planting interval and the planting depth when the seedling planting unit 150 performs the planting operation, Information on the setting of the working device such as the amount of fertilizer applied when performing work and the type or composition of fertilizer supplied to the field 350 is also stored. These pieces of work information are transmitted as work information to the terminal communication unit 304 by the seedling transplanter communication unit 251 as control information of the fertilization amount adjustment motor 186 controlled by the controller 250 and the solenoid 203 of the medicine supply device 201. Obtained by the tablet terminal device 300. Thus, the tablet terminal device 300 which acquired the work information of the seedling transplanter 100 stores the work information in the storage unit 303.

  As described above, when the work information is stored in the tablet terminal device 300, the position information when the work is performed is also stored. This position information is acquired by the GPS control device 220. Specifically, the GPS control device 220 acquires position information of the seedling transplanter 100 on the earth at predetermined time intervals by receiving a signal from an artificial satellite used in GPS by the receiving antenna 221. At that time, the GPS control device 220 appropriately expands / contracts the expansion / contraction cylinder 227 according to the control signal from the controller 250, so that the direction of the reception antenna 221 is set to be easy to receive the signal from the artificial satellite. When transmitting the work information to the tablet terminal device 300, the controller 250 transmits the position information acquired by the reception antenna 221 in this way in association with the work information. Thereby, the tablet terminal device 300 stores the work information for each work position when the work information is stored in the storage unit 303.

  Moreover, as information memorize | stored in the tablet terminal device 300, not only the work information of the tractor 10 and the seedling transplanter 100 but the field information which is the information of the field 350 is also memorize | stored. As the field information, for example, the fertilizer concentration detected by the fertilizer concentration sensor 230 of the seedling transplanter 100 and acquired by the controller 250 is stored. When storing the fertilizer concentration, first, when the fertilizer concentration is acquired by the controller 250, the detection result of the fertilizer concentration sensor 230 is acquired, and the position information acquired from the detection result is obtained from the GPS control device 220. get. The controller 250 associates the fertilizer concentration detected by the fertilizer concentration sensor 230 with the position information acquired by the GPS control device 220 and transmits it to the tablet terminal device 300. Thereby, the tablet terminal device 300 stores the fertilizer concentration for each position in the field 350 in the storage unit 303. Thus, when storing the farm field information in the tablet terminal device 300, the information for each position in the farm field 350 is stored. In other words, the tablet terminal device 300 stores the amount of soil components detected by the fertilizer concentration sensor 230 for each position in the field 350.

  Similarly, when the scraping device 70 is connected to the traveling vehicle body 11 of the tractor 10 and the scraping operation is performed, the soil acidity detected by the pH sensor 71 is also the position information detected by the GPS control device 50 as field information. At the same time, it is stored in the tablet terminal device 300.

  Further, when the tractor 10 is working on the field 350, the suspension of the traveling vehicle body 11 expands and contracts due to the undulation and hardness of the field 350. The stroke sensor 65 provided in the tractor 10 detects the depth of the field 350 by detecting the amount of expansion / contraction of the suspension. That is, the farm field 350 is configured by stacking a plow, which is hard soil that is not cultivated, and a top soil, which covers the plow and is cultivated, but the amount of expansion and contraction of the suspension is It varies depending on the thickness of this topsoil as well as the ups and downs.

  Specifically, in a portion where the topsoil is thick, the amount of sinking of the wheel into the topsoil when traveling with the traveling vehicle body 11 increases, and thus the amount of expansion and contraction of the suspension increases. On the other hand, the amount of subsidence of the wheel is small in the portion where the topsoil is thin, so that the amount of expansion and contraction of the suspension is small. The stroke sensor 65 detects the thickness of the topsoil, that is, the depth of the field 350, by detecting the expansion / contraction amount of the suspension whose expansion / contraction amount varies depending on the topsoil thickness. The tablet terminal device 300 stores the depth of the field 350 detected by the stroke sensor 65 during the operation of the tractor 10 together with the position information detected by the GPS control device 50 in the storage unit 303, thereby reducing the depth of the field 350. Stored as information for each position. Further, when storing the farm field 350 in the tablet terminal device 300, the entire average depth of the farm field 350 is calculated, and the average depth is also stored.

  In addition, the tablet terminal device 300 stores, as field work information, the amount of fertilizer applied at the time of seedling planting or seeding on the field 350, the date of harvest work, and the yield. These field work information is obtained by communicating the work information when working with the seedling transplanter 100 and other work devices between the work device and the tablet terminal device 300, by the tablet terminal device 300. It is automatically acquired or stored when an operator performs an input operation on the touch panel 301.

  Based on the past work information stored as described above, the tablet terminal device 300 performs a work plan for work to be performed in the future. This work plan is performed by creating a work map in which work information and field information of the tractor 10 and the seedling transplanter 100 are linked to position information, and appropriately cultivating cultivated crops when working on the field. Each adjustment value such as the amount of fertilizer necessary to do is planned based on past information. As described above, when the work plan is performed by the tablet terminal device 300, the work plan for the information desired by the worker is performed by an input operation to the tablet terminal device 300. For example, any one of information on the types of crops, fertilizers, and medicines, information on the crop yield, and information on the setting of the work device is selected by an input operation to the touch panel 301 included in the tablet terminal device 300.

  When the information is selected, the tablet terminal device 300 creates a work plan based on the information selected by the worker and the information stored in the storage unit 303. In this work plan, the optimum cultivation start time of the crop at that time, the timing of mid-cultivation work such as topdressing and water volume management, the harvest start timing of the crop, the type and amount of fertilizers and drugs used for cultivation of the crop A work plan including at least one of the above is created. By performing work based on the work plan created in this way, the worker can perform appropriate work regardless of the type of crop, the type of fertilizer, and the like.

  The tablet terminal device 300 that has performed the work plan displays desired information such as an appropriate fertilizer amount on the touch panel 301 based on the information selected by the worker when the work is performed according to the work plan. The work according to the work plan can be performed by prompting the work or automatically controlling the work apparatus via communication between the tablet terminal device 300 and the work vehicle.

  When performing a work plan with the tablet terminal device 300 as described above, for example, using the field information regarding the fertilizer concentration of the field 350 detected and acquired by the fertilizer concentration sensor 230 during the work with the seedling transplanter 100. Then, a work map is created, and it is used as a reference when working with the tractor 10 after the farm 350 has been cut up and cut. That is, when working with the tractor 10, the work position and operation of the tillage device 40 are changed in accordance with the fertilizer concentration stored in the tablet terminal device 300.

  For example, in the field 350, at a location where the fertilizer concentration is higher than a predetermined value, the work height of the tilling device 40 is increased, so that the ground work of only the surface layer portion is performed, and only the surface layer portion of the field field 350 is plowed. On the other hand, in the field 350, at a place where the fertilizer concentration is lower than the predetermined value, the work height of the tillage device 40 is lowered to cause the ground work to be performed from the surface layer part to the deep layer part, and only the surface layer part of the field field 350 is performed. Not only the deep layer but also tilling. As described above, the work position and operation of the tilling device 40 are changed by transmitting a control signal from the tablet terminal device 300 to the controller 80 of the tractor 10 and controlling the hydraulic cylinder 32 for lifting the work implement via the controller 80. To automatically adjust the fertilizer concentration in the field 350.

  In addition, when changing operation | movement according to a fertilizer density | concentration, you may carry out by methods other than this. For example, at a location where the fertilizer concentration is higher than a predetermined value, the soil of the surface layer portion is mixed with the soil of the deep layer portion at the time of tillage work by decreasing the rotation speed of the tillage device 40 or increasing the traveling speed of the traveling vehicle body 11. It may not be possible. On the other hand, at locations where the fertilizer concentration is lower than the predetermined value, the rotational speed of the tillage device 40 is increased or the traveling speed of the traveling vehicle body 11 is decreased so that the soil in the surface layer and the soil in the deep layer are mixed well. May be. Further, the work position and operation of the tilling device 40 may be changed by a technique other than automatic adjustment via the controller 80. For example, the tablet terminal device 300 calculates the height and number of rotations of the tillage device 40 and the value of the traveling speed of the traveling vehicle body 11 for each position of the field 350 based on the fertilizer concentration stored in the storage unit 303. By displaying 301, the operator may change the operation by appropriately operating the tractor 10 based on the display.

  In the work plan using the tablet terminal device 300, the tablet terminal device 300 stores the field work information such as the fertilization amount and harvesting work date stored in the tablet terminal device 300 and the fertilizer concentration detected by the fertilizer concentration sensor 230. The optimum fertilizer concentration and soil acidity are calculated by comparing the amount of soil components detected by the pH sensor 71 and the soil acidity. In other words, the tablet terminal device 300 performs the harvesting based on the soil acidity recorded at the time of planting the seedling, the date of harvesting with the combine (not shown), and the yield obtained thereby. It is determined whether or not the amount is a theoretical value in the field 350. By this determination, when the harvest amount has reached the theoretical value, it is determined that the soil component amount is good, and when the harvest amount has not reached the theoretical value, the soil component amount is not good. And judge. As described above, when the acidity of the detected soil and the determination on the acidity are performed, the data about the determination is also stored, and the next time the field 350 or the soil improvement is performed, the field 350 Calculate what kind of work should be done for. Thereby, the optimal fertilizer density | concentration and soil acidity for making a yield into a theoretical value are calculated.

  The tablet terminal device 300 displays the operation amount of the fertilization amount adjustment motor 186 and the operation amount of the fertilization selector 188 on the touch panel 301 based on the fertilizer concentration and the soil acidity calculated as described above. The operator visually recognizes these operation amounts displayed on the touch panel 301 and operates the fertilization amount adjusting motor 186 and the fertilization selector 188 to supply the fertilization amount when the fertilizer is applied by the fertilizer 170 or to the field 350. The type of fertilizer to be used, that is, the component of the fertilizer is switched. The fertilizer device 170 adjusts the fertilizer amount and the fertilizer component as described above, thereby changing the soil component amount to the proper component amount of the cultivated crop based on the soil component amount stored in the tablet terminal device 300. The fertilizer of the component which can be supplied can be supplied.

  In addition, when switching the fertilizer amount and the fertilizer supplied to the field 350 in this way, the fertilizer amount adjusting motor 186 and the fertilizer selector 188 may be automatically controlled by operating the tablet terminal device 300. That is, by performing communication between the tablet terminal device 300 and the controller 250, the fertilizer application amount adjusting motor 186 and the fertilizer application selector 188 may be operated via the controller 250 so that a desired operation amount is obtained.

  In addition, when adjusting the fertilization according to the work plan using the tablet terminal device 300, the supply amount and type of fertilizer are obtained in consideration of the cultivated crops grown in the field 350 where fertilization is performed, and fertilization according to the cultivated crops is performed. To be able to do. Specifically, the tablet terminal device 300, when working on the seedling transplanter 100 or the tractor 10, applies the fertilizer amount in the fertilizer device 170 as the field work information and the soil components detected by the fertilizer concentration sensor 230 or the pH sensor 71. The amount and the cultivated crop in the field 350 are stored. The cultivated crop is input to the tablet terminal device 300 and stored in the storage unit 303 when the operator performs an input operation on the touch panel 301 when working on the field 350.

  The tablet terminal device 300 is the time when the fertilizer needs to be added in order to properly cultivate the cultivated crop from the fertilization amount stored in the tablet terminal device 300, the amount of the soil components, and the cultivated crop. The additional amount and the type of fertilizer are calculated and displayed on the touch panel 301. The worker visually recognizes the information displayed on the touch panel 301, and performs fertilization work by the fertilizer applying apparatus 170 based on the displayed information, thereby performing fertilization suitable for cultivating any cultivated crop.

  In the work plan using the tablet terminal device 300, the work vehicle that performs work in the next process in the field 350 in which the work information, the field information, and the field work information are stored in the tablet terminal device 300 is the tablet terminal device 300. The operation of the work device or the like is adjusted based on the stored depth of the field 350 for each position. That is, when the work vehicle that performs the work in the next process of the tractor 10 that has detected the depth is the seedling transplanter 100, seedling planting is performed based on the depth of the field 350 at each position stored in the tablet terminal device 300. Lifting / lowering operation of the unit 150, increase / decrease of fertilizer supply amount, vertical adjustment of seedling transplanting height or seed sowing operation height, setting of working conditions of the automatic lifting mechanism of the seedling planting unit 150, seedling according to the depth of the field 350 The touch panel 301 of the tablet terminal device 300 notifies at least one of the difficult work locations in the transplanter 100.

  That is, the raising / lowering amount when raising / lowering the seedling planting part 150 by the seedling planting part raising / lowering mechanism 140, the supply amount of fertilizer when fertilizing with the fertilizer application apparatus 170, and the seedling transplanting work height by the seedling planting part 150 Adjustment amount, adjustment amount of seed sowing work height, setting of conditions for raising and lowering when seedling planting part 150 is raised and lowered by an automatic raising and lowering mechanism, the wheel is likely to sink due to the oversoil being too thick The operator is notified by displaying at least one of the existing positions on the touch panel 301. In this case, the setting of the conditions relating to the raising / lowering by the automatic raising / lowering mechanism is the setting of the hydraulic sensitivity when the seedling planting part raising / lowering mechanism 140 is operated with respect to the vertical movement of the float 147. An operator who visually recognizes the display on the touch panel 301 operates the seedling planting unit 150 based on the display, or operates the seedling transplanter 100 so as to avoid difficult work locations. Appropriate planting work can be performed regardless of the depth.

  It should be noted that, based on the depth of the field 350 in this way, the seedling planting part 150 is raised and lowered, the setting of the working conditions of the automatic lifting mechanism of the seedling planting part 150 is changed, and the difficult work part is avoided. When performing work, these may be performed by automatic control. In other words, by communicating between the tablet terminal device 300 and the controller 250, the seedling planting unit lifting mechanism 140 is operated via the controller 250 so that a desired operation amount is obtained, or seedlings are avoided while avoiding difficult work locations. The automatic steering device 210 may be controlled via the controller 250 so that the operation of the transplanter 100 traveling is performed by the automatic steering device 210.

  In addition, in the work plan using the tablet terminal device 300, when performing the ground work with the work device such as the tilling device 40, the work plan is performed so that the work in consideration of the influence of water on the farm field 350 can be performed. . That is, since the flow of water is large in the vicinity of the intake gate 351 and the drainage gate 356, the soil of the farm field 350 easily flows together with the water. For this reason, if the soil is over-stirred with the tilling rotary 44 of the tilling device 40 or the scraping with the substitute scraping device 70 is strongly carried out, it becomes easy to create a portion having a depth that makes it difficult to run on the work vehicle. Accordingly, in such a portion, the work plan is performed so that the depth at the time of working with the tilling device 40 or the plowing device 70 becomes shallow.

  When performing this work plan, the tablet terminal device 300 stores the position coordinates of the intake gate 351 and the drainage gate 356 of the farm field 350 in the storage unit 303. The position coordinates of the intake gate 351 and the drainage gate 356 may be acquired from the map data by the tablet terminal device 300 or may be input by an operator through an input operation on the touch panel 301.

  When the position coordinates of the tractor 10 performing the work in the field 350 in which the position coordinates of the intake gate 351 and the drainage gate 356 are stored in the tablet terminal device 300 are the position coordinates of the intake gate 351 and the drainage gate 356, the tilling device The ground work by 40 or the scraping device 70 is performed in a shallow area of the soil. Specifically, the working speed of the traveling vehicle body 11 when working with the tilling device 40 or the tilling device 70 is increased, the working height of the tilling device 40 or the shaving device 70 is increased, the rotational speed of the tilling device 40 is decreased, or the working speed is increased. Make it faster. By displaying the operation amount and traveling speed of the work device on the touch panel 301, the operator may perform operations according to the displayed operation amount and traveling speed. Control and adjustment of traveling speed may be performed by the tablet terminal device 300 via the controller 80.

  Note that the position coordinates of the tractor 10 do not have to be strictly the position coordinates of the intake gate 351 and the drainage gate 356. The position from the intake gate 351 or the drainage gate 356 is set as a position for determining whether or not to perform these controls, and the position of the tractor 10 from the intake gate 351 or the drainage gate 356 is set in advance. When the position coordinates are within the set range, these controls may be performed. As described above, in the vicinity of the intake gate 351 and the drainage gate 356, the work of the tilling device 40 and the alternative scraping device 70 is not performed strongly, so that the soil can easily flow along with the water. In the vicinity of the gate 356, the working device should not mix the soil deeply.

  Further, when the work plan is performed by the tablet terminal device 300, the plan is made in consideration of the amount of water in the field 350. In order to perform work planning in consideration of the amount of water in the field 350, the tablet terminal device 300 determines the value of the field 350 from the average value of the detection value in the first water amount sensor 353 and the detection value in the second water amount sensor 358. Calculate the amount of water. The detection values obtained by the first water amount sensor 353 and the second water amount sensor 358 are acquired by the tablet terminal device 300 via the server 310.

  Specifically, the detection results of the first water amount sensor 353 and the second water amount sensor 358 are transmitted to the water amount adjustment control device 365 and acquired by the water amount adjustment control device 365. The water amount adjustment control device 365 acquires the detection values of the first water amount sensor 353 and the second water amount sensor 358 by performing wireless communication between the water amount adjustment communication unit 366 and the server communication unit 312 included in the server 310. And stored in the storage unit 311. The tablet terminal device 300 performs wireless communication between the terminal communication unit 304 and the server communication unit 312, so that the first water amount sensor 353 and the second water amount sensor 358 stored in the storage unit 311 of the server 310 are used. A detection value is acquired and stored in the storage unit 303. Thereby, the tablet terminal apparatus 300 acquires the detection value in the 1st water amount sensor 353 or the 2nd water amount sensor 358.

  In addition, since the intake gate 351 and the drainage gate 356 are installed at a position lower than the intake gate 351 in order to ensure drainage at the drainage gate 356, the first water amount sensor 353 and the first drainage gate 356 are disposed. The amount of water detected by the two water amount sensors 358 is different. For this reason, when detecting the amount of water in the field 350, the average value of the value detected by the first water amount sensor 353 and the average value of the value detected by the second water amount sensor 358 is obtained. calculate. The amount of water calculated in this way is stored in the storage unit 303.

  The tablet terminal device 300 calculates the time when fertilizer needs to be added to the field 350, the added amount of fertilizer, and the type of fertilizer from the stored amount of water, and displays them on the touch panel 301. Specifically, the tablet terminal device 300 continuously acquires a change in the amount of water from when water is poured into the field 350 to perform the scraping operation until the rice grows and drains water from the field 350. For each type of fertilizer, the fertilizer supplied to the field 350 is less likely to flow out together with water, and the fertilizer application timing and amount at which less fertilizer remains without being consumed are calculated. The next time the same rice is cultivated in the same field 350, the field 350 is filled with water by applying fertilization with the fertilization time, amount of fertilizer, and type of fertilizer calculated by the tablet terminal device 300 based on the amount of water. It is possible to perform appropriate fertilization during the period.

  In the farm work support system 1 according to the above embodiment, the tablet terminal device 300 changes the work position and operation of the tillage device 40 according to the fertilizer concentration of the farm field 350 acquired by the fertilizer concentration sensor 230. In a place where the fertilizer concentration is high, the soil in the deep layer with a large amount of fertilizer components can be maintained by performing an operation in which the soil in the surface layer is not mixed with the soil in the deep layer. Thereby, the quantity of the fertilizer supplied when planting a crop can be reduced. On the other hand, in a place where the fertilizer concentration is low, mixing the surface soil with the deep soil allows the surface soil with less fertilizer components and the deep soil with relatively high fertilizer components to be mixed. Can be matched. Thereby, fertilizer density | concentration is stabilized regardless of depth, and when supplying fertilizer, excess and deficiency can be made hard to produce. As a result, the work in the field 350 can be made an appropriate work regardless of the fertilizer concentration in the field 350.

  In addition, the tablet terminal device 300 stores the amount of soil components detected by the fertilizer concentration sensor 230 and the pH sensor 71, and the fertilizer application device 170 is based on the amount of soil components stored in the tablet terminal device 300. In order to supply the fertilizer of the component that can make the amount of the component the proper component amount of the cultivated crop, supply the fertilizer of the corresponding component so that the amount of the component of the soil becomes the component amount suitable for the growth of the cultivated crop be able to. As a result, it is possible to prevent the crop from being cultivated in soil that is not suitable for growth, so that the growth of the crop can be stabilized and the quality can be improved. As a result, regardless of the fertilizer concentration in the field 350, the work in the field 350 can be made more appropriate.

  In addition, the tablet terminal device 300 stores the depth of the field 350 detected by the stroke sensor 65 during the operation of the tractor 10 for each position detected by the GPS control device 50, and the seedling transplanter 100 that performs the operation in the next process, etc. The work vehicle performs a switching operation of work conditions at an appropriate timing by issuing a notification of changing the setting of the work vehicle based on the depth of the field 350 stored for each position stored in the tablet terminal device 300. be able to. As a result, work efficiency and work accuracy can be improved, and work can be performed while avoiding places where work is difficult, so that work can be prevented from being interrupted. Further, when the setting of the work vehicle is automatically controlled based on the stored depth of the field 350, the operation condition can be switched at an appropriate timing without the operator's operation. Can reduce the labor of a person. As a result, an appropriate operation can be performed on the field 350 more reliably.

  In addition, when the position coordinates of the tractor 10 to which the scraping device 70 is connected are the position coordinates of the intake gate 351 and the drainage gate 356, or when the position coordinates thereof are within the set range, the tilling device By increasing the working height of the working device 40 or the scraping device 70, decreasing the rotational speed of the tilling device 40, or increasing the traveling speed of the traveling vehicle body 11 when working with these working devices, Can not be mixed. That is, in the vicinity of the intake gate 351 and the drainage gate 356 where the soil is easily washed away by entering and leaving the water, the soil can be kept hard enough to be washed away by performing shallow tillage and plowing. Thereby, it can prevent that the periphery of the intake gate 351 and the drainage gate 356 becomes a location where work becomes difficult at the time of the work of a post process resulting from becoming deeper than other locations. Further, in the vicinity of the intake gate 351 and the drainage gate 356, it is possible to prevent a large amount of soil containing fertilizer components from flowing out of the field 350 by plowing and plowing, so use of fertilizer supplied during cultivation The amount can be reduced and river pollution can be prevented.

  Further, the tablet terminal device 300 compares the field work information such as fertilization amount and harvesting work date with the amount of soil components detected by the fertilizer concentration sensor 230 and the pH sensor 71, so that the optimum fertilizer concentration and soil acidity are compared. The operation amount of the fertilizer adjustment motor 186 and the operation amount of the fertilizer selector 188 are displayed on the touch panel 301 based on the calculated fertilizer concentration and soil acidity, or these are automatically controlled. Thus, the amount of fertilizer to be supplied and the components can be changed based on the fertilization amount, harvest date and yield. Thereby, since the next cultivated crop can be cultivated under better conditions, the growth can be stabilized and the yield can be increased. Moreover, since the corresponding fertilizer can be supplied to the position where the fertilizer concentration is low in the field 350 or where the acidity is inappropriate, the supply amount of the fertilizer in the entire field 350 is increased or the acidity is changed. The amount of soil components can be made appropriate without supplying fertilizer. Thereby, the usage-amount of a fertilizer can be reduced.

  In addition, the time required for adding fertilizer, the amount of additional fertilizer, and the type of fertilizer are calculated from the fertilizer applied, the amount of soil components, and the cultivated crop stored in the tablet terminal device 300, and are displayed on the touch panel 301. It is possible to prevent the occurrence of a shortage of fertilizer. As a result, the growth of the crop is stabilized, the quality is improved, and planned work is possible. Moreover, since it can prevent supplying excess fertilizer by calculating these, while being able to prevent the quality fall by excessive fertilizer, weeds can be prevented from growing with surplus fertilizer. Thereby, reduction of the usage-amount of a chemical | medical agent required for weeding work and reduction of work labor can be aimed at.

  In addition, the tablet terminal device 300 uses the amount of water in the field 350 calculated based on the detection values of the first water amount sensor 353 and the second water amount sensor 358, and when the fertilizer needs to be added to the field 350. Since the amount and the type of fertilizer are calculated and displayed on the touch panel 301, extra fertilizer components can be discharged by entering and exiting water during the next work, or excessive outflow of fertilizer components can be prevented. Thereby, while being able to reduce the quantity of the fertilizer supplied to the agricultural field 350, the contamination of a river can be prevented.

[Modification]
In addition, in the seedling transplanter 100 used for the agricultural work support system 1 according to the embodiment, the fertilizer application device 170 is configured to supply fertilizer from a preset height to the farm field 350. The seedling transplanter 100 may be configured to change the fertilizer supply height to the field 350. FIG. 15 is a modified example of the seedling transplanter used in the farm work support system according to the embodiment, is an explanatory view of a fertilizer duct, and is a plan view of the fertilizer duct. FIG. 16 is a side view of the fertilizer duct shown in FIG. In the case where the fertilizer 170 supplies paste-like fertilizer, a fertilizer duct 320 that is a fertilizer guide member that guides the fertilizer supplied from the fertilizer 170 into the soil is provided in the vicinity of the float 147. The fertilizer may be supplied so that the discharge port 321 which is a fertilizer supply port in the fertilizer duct 320 faces the soil. Moreover, when supplying fertilizer using the fertilizer duct 320 in this way, the supply height of the fertilizer to the farm field 350 may be changed by changing the height of the discharge port 321.

  When the height of the discharge port 321 can be changed, for example, the fertilizer duct 320 extends substantially in the front-rear direction, and the front end of the fertilizer duct 320 is connected to a rotation shaft 322 that extends in the left-right direction. A fertilizer duct 320 is provided so as to be rotatable about a moving shaft 322. In this case, it is located at the rear end of the discharge port 321. Thus, the rotation shaft 322 that is the rotation center of the fertilizer duct 320 is a power source for rotation of the fertilizer duct 320 and is a rotation actuator that changes the supply depth of the fertilizer in the fertilizer duct 320. The duct is rotated by the power generated by the duct rotation motor 325.

  Specifically, the power generated by the fertilizer duct rotation motor 325 is generated by meshing a fan-shaped gear provided as an output side gear with a pinion gear provided on the output shaft of the fertilizer duct rotation motor 325. It is made to take out with the rotation gear 326. Further, the fan-shaped gear in the fertilizer duct rotation gear 326 and the rotation shaft 322 are connected by the fertilizer duct rotation wire 327, so that the power generated by the fertilizer duct rotation motor 325 is transmitted to the fertilizer duct rotation gear 326. And the fertilizer duct turning wire 327 so that it can be transmitted to the turning shaft 322. As a result, the rotation shaft 322 can be rotated by the power generated by the fertilizer duct rotation motor 325, and by rotating the fertilizer duct 320 around the rotation shaft 322, the vertical position of the discharge port 321 can be changed. It can be changed.

  Further, a potentiometer 323 for detecting the rotation angle of the fertilizer duct 320 is provided in the vicinity of the rotation shaft 322 so that the rotation angle of the fertilizer duct 320 can be detected. The potentiometer 323 and the fertilizer duct rotation motor 325 are both electrically connected to the controller 250. Thus, the fertilizer duct rotation motor 325 can be operated while the detection result of the potentiometer 323 is acquired by the controller 250, and the rotation angle of the fertilizer duct 320 can be set to a desired rotation angle.

  When the fertilizer is supplied by the fertilizer duct 320 that can change the supply height of the fertilizer by rotating in this way, an operation plan that also considers the supply height of the fertilizer may be performed. When performing the work plan in this manner, the tablet terminal device 300 stores the fertilizer supply depth in the fertilizer duct 320 for each position detected by the GPS control device 220. Furthermore, from the crop yield stored in the tablet terminal device 300, it is necessary to apply an appropriate fertilizer supply depth, when it is necessary to add fertilizer, the amount of fertilizer added, the type of fertilizer, and the application of herbicides and insecticides. And the type of herbicide and pesticide. For example, the supply depth of a fertilizer for calculating a more appropriate soil component is calculated from the previous crop yield, or the time for adding the fertilizer is calculated. In addition, based on the time when crops to be cultivated are likely to become sick, the time when fertilizer supply, spraying of herbicide and insecticide is necessary is calculated.

  Based on the calculated fertilizer supply depth, the tablet terminal device 300 that has calculated them operates the fertilizer duct rotation motor 325, the fertilizer application amount adjustment motor 186 that the fertilizer 170 has, and the solenoid 203 that the medicine sprayer 190 has. The amount is displayed on the touch panel 301. For example, the rotation angle or the like of the fertilizer duct 320 is displayed on the touch panel 301 and the operator is prompted to perform an operation for rotating the fertilizer duct 320.

  As described above, the operator visually recognizes the operation amount displayed on the touch panel 301 and operates each unit with the displayed operation amount, so that the fertilizer can be supplied to a position suitable for the growing stage of the crop. Thereby, while being able to stabilize growth of a crop, the frequency | count of adding a fertilizer can be reduced and the consumption of a fertilizer can be reduced. In addition, by calculating the time, amount and type of fertilizer added, it is possible to prevent the occurrence of a shortage of fertilizer used by the crop, so that the growth of the crop can be stabilized and the quality can be improved. And plan work can be made possible. In addition, since it is possible to prevent supply of excess fertilizer, it is possible to prevent deterioration of quality due to excessive fertilizer, to prevent weeds from growing with surplus fertilizer, and to reduce the amount of drug used for weeding work, Work labor can be reduced.

  In addition, by changing the supply amount of the drug, it is possible to prevent the occurrence of excess or deficiency of the drug, so that weeds grow due to the drug shortage and the cultivated crops cause poor growth, or pests occur and die. Can be prevented and the growth and yield of the crop can be stabilized. Moreover, it can prevent that a chemical | medical agent is oversupplied and a cultivation crop dies, and water and soil are contaminated.

  In addition, when adjusting fertilization and chemical | medical agent dispersion | distribution based on the calculated fertilizer supply depth, you may control automatically the fertilization amount adjustment motor 186 and the solenoid 203 by operation of the tablet terminal device 300. FIG. That is, these automatic controls may be performed via the controller 250 by performing wireless communication between the tablet terminal device 300 and the controller 250.

  Moreover, in the agricultural work support system 1 which concerns on embodiment, although the pH sensor 71 is provided as the component amount detection member in the scraping apparatus 70 connected with the tractor 10, other than the pH sensor 71 is provided as a component amount detection member. Also good. For example, the fertilizer concentration sensor 230 provided on the wheel of the seedling transplanter 100 in the embodiment may be provided on the grounding roller provided at the rear end of the alternative scraping device 70. Thereby, the change in the fertilizer concentration before and after the scavenging by the scavenging device 70, that is, the change in the fertility can be detected more accurately.

  In the farm work support system 1 according to the embodiment, the depth of the field 350, that is, the thickness of the topsoil is detected by the stroke sensor 65 provided in the tractor 10, but the depth of the field 350 is determined by the stroke sensor. You may detect by other than 65. For example, the tractor 10 may be provided with an ultrasonic sensor (not shown), and the depth of the field 350 may be detected by the ultrasonic sensor. In this case, the ultrasonic sensor is provided so that a distance from the ultrasonic sensor can be detected by emitting an ultrasonic wave downward and detecting a reflected wave. The ultrasonic wave generated from the ultrasonic sensor provided in this way easily passes through the relatively soft topsoil and is easily reflected by a hard tiller. For this reason, by detecting the reflected wave reflected by the cultivator, the distance to the cultivator can be detected, and the depth of the field 350 can be detected. The depth detecting member for detecting the depth of the field 350 is not limited as long as it can detect the distance to the tiller as described above.

  Further, in the agricultural work support system 1 according to the embodiment, the time of top dressing is calculated based on the amount of water calculated from the detection values of the first water amount sensor 353 and the second water amount sensor 358. It may be calculated based on other than this. For example, the time of top dressing is set up based on the acidity of the soil detected by the pH sensor or the fertilizer concentration detected by the fertilizer concentration sensor by providing a pH sensor or a fertilizer concentration sensor near the drainage gate 356 in the field 350. Time etc. may be calculated. That is, in the field 350, since the fertilizer component tends to accumulate in the drainage gate 356 whose height is lower than other parts, the excess or deficiency of the fertilizer in the entire field 350 is estimated by detecting the soil component in this part. can do. Thus, by detecting the components of the soil in the vicinity of the drainage gate 356, it is possible to estimate the excess and deficiency of the fertilizer in the entire field 350. Therefore, based on the components of the soil in the vicinity of the drainage gate 356, Time etc. may be calculated.

  Moreover, in the agricultural work support system 1 according to the embodiment, water intake of the farm field 350 is performed by opening the water intake gate 351, but water intake of the farm field 350 may be performed using a pump. In this case, a flow meter is provided on the drainage gate 356 side to measure the amount of drainage of the water, the difference between the amount of water taken by the pump and the drainage amount on the drainage gate 356 side is calculated, and the drainage gate according to the difference The opening / closing of 356 may be adjusted. In other words, if there is a large amount of drainage relative to the amount of water taken in, it is highly possible that not only water but also earth and sand are being discharged at the time of drainage. In this case, the drainage of the earth and sand is prevented by temporarily stopping the drainage. You may make it prevent the outflow of the fertilizer which flows out with it.
