The transmission ratio of the third transmission gear 43 and the third gear 63 is smaller than the transmission ratio of the fourth transmission gear 44 and the fourth gear 64.

  The fourth transmission gear 44 is located closer to the pulley 42b than the third transmission gear 43. A planetary gear mechanism 69 is provided between the fourth transmission gear 44 and the pulley 42b. The planetary gear mechanism 69 includes an internal gear, a sun gear, and a planetary gear. Teeth that mesh with the sixth gear 66 are formed on the outer periphery of the internal gear. The sun gear is provided on the sorting drive shaft, and a planetary gear is provided between the sun gear and the internal gear. A fifth transmission gear 45 is provided between the planetary gear mechanism 69 and the pulley 42b.

  The transmission mechanism 100 includes a first drive shaft 70 and a second drive shaft 74 that are parallel to the sorting drive shaft. The first drive shaft 70 is located next to the planetary gear mechanism 69. The first drive shaft 70 is provided with a first drive gear 71 that meshes with the fifth transmission gear 45 and a second drive gear 72. The second drive shaft 74 is provided with a third drive gear 73 that meshes with the second drive gear 72. The third drive gear 73 transmits power to the feed chain 5.

  When the first transmission cylinder 58 is connected to the first transmission gear 51 or the second transmission gear 52, the driving force from the HST 41 and the driving force from the engine 40 are combined in the planetary gear mechanism 69, and the feed chain 5 Communicated.

  FIG. 6 is a cross-sectional view of the transmission mechanism when the first transmission cylinder 58 is connected to the second gear 57. The arrows in FIG. 6 indicate the direction in which the driving force from the engine 40 or HST 41 is transmitted. For example, when the work clutch lever 85 is in the “cutting” position and the main transmission lever 84 is positioned on the “forward” side, or when the cutting shift button is operated and “high speed” is changed to “standard”, The first transmission cylinder 58 moves to the second gear 57 side and is connected to the second gear 57. In FIG. 6, the second transmission cylinder 62 is disposed at the neutral position.

  The driving force of the HST 41 is input to the planetary gear mechanism 69 via the input shaft 50, the first transmission shaft 53, and the second transmission shaft 60. The driving force of the engine 40 is also input to the planetary gear mechanism 69. In the planetary gear mechanism 69, the driving forces of the HST 41 and the engine 40 are combined and transmitted to the feed chain 5. The driving force of the HST 41 synchronizes with the vehicle speed and the driving force from the engine 40 is substantially constant, so the feed chain 5 rotates in synchronism with the vehicle speed.

  The driving force of the HST 41 is transmitted to the cutting unit 3 through the input shaft 50, the first transmission shaft 53, the second transmission shaft 60, and the cutting transmission shaft 68. As described above, the driving force from the engine 40 is transmitted to the cylinder and the swing arm.

  FIG. 7 is a cross-sectional view of the transmission mechanism when the first transmission cylinder 58 is connected to the first gear 55. The arrows in FIG. 7 indicate the direction in which the driving force from the engine 40 or HST 41 is transmitted. For example, when the work clutch lever 85 is in the “cutting” position and the main transmission lever 84 is set to the “forward” side, the cutting gear change button is operated, and “standard” is changed to “high speed”. In this case, the first transmission cylinder 58 moves to the first gear 55 side and is connected to the first gear 55.

  In this case, except that the first transmission cylinder 58 is connected to the first gear 55, the connection relationship and power transmission path of the transmission mechanism 100 are substantially the same as the connection relation and transmission path shown in FIG. As described above, since the gear ratio of the first gear 55 and the first transmission gear 51 is smaller than the gear ratio of the second gear 57 and the second transmission gear 52, the cutting unit 3 is more than the case shown in FIG. Drive at high speed.

  FIG. 8 is a cross-sectional view of the transmission mechanism when the first transmission cylinder 58 is in the neutral position. The arrows in FIG. 8 indicate the direction in which the driving force from the engine 40 or HST 41 is transmitted. For example, when the work clutch lever 85 is in the “cutting” position and the cutting quick pedal 86 is stepped on, current is supplied to the electromagnet, the first electric cylinder is placed in the neutral position, and the second transmission cylinder 62 is in the first position. 4 gears 64 are connected.

  In this case, transmission of the driving force from the input shaft 50, that is, the HST 41 to the first transmission shaft 53 is cut off, and the driving force from the engine 40 is input to the cutting unit 3 through the torque limiter 68b, and the cutting unit 3 is substantially constant. Rotates at speed.

  The driving force of the engine 40 is input to the planetary gear mechanism 69 via the second transmission shaft 60 and the sixth gear 66, and is combined with the power from the sorting drive shaft by the planetary gear mechanism 69 and transmitted to the feed chain 5. Is done. The feed chain 5 rotates at a substantially constant speed.

  In addition, when the cutting part 3 is rotating at a predetermined speed or higher, when the cutting quick pedal is stepped on, or when the rotational speed of the cutting part 3 approaches the predetermined speed, the first transmission cylinder 58 is in the neutral position. The second transmission cylinder 62 is connected to the third gear 63.

  In this case, except that the second transmission cylinder 62 is connected to the third gear 63, the connection relation and power transmission path of the transmission mechanism 100 are substantially the same as the connection relation and transmission path shown in FIG. As described above, since the gear ratio of the third transmission gear 43 and the third gear 63 is smaller than the gear ratio of the fourth transmission gear 44 and the fourth gear 64, the cutting unit 3 is more than the case shown in FIG. Drive at high speed.

  FIG. 10 is a flowchart for explaining loss amount data collection / transmission processing by the control unit 90. The CPU 91 of the control unit 90 determines whether or not cutting is started (step S1). The CPU 91 acquires a signal from the work clutch lever 85 and determines whether or not the work clutch lever 85 is in the “cutting” position. . When the work clutch lever 85 is not in the “cutting” position, that is, when cutting is not started (step S1: NO), the CPU 91 returns the process to step S1.

  When the work clutch lever 85 is in the “cutting” position, that is, when cutting is started (step S1: YES), the CPU 91 uses the timer 91a to start measuring time (step S2). The CPU 91 acquires the combine position information from the artificial satellite 98 via the transmission / reception unit 95 and stores it in the storage unit 94 every predetermined time, and stores the time in the storage unit 94 with reference to the timer 91a. Are continuously executed as a subroutine (step S3). For example, the CPU 91 stores the combine position information and time in the storage unit 94 in association with the elapse of a predetermined time (for example, every elapse of 0.5 seconds).

  The CPU 91 acquires the moving speed of the tine 3d from the tine speed sensor 88 and stores it in the storage unit 94, and stores the time in the storage unit 94 with reference to the timer 91a (step S4). CPU91 acquires the moving speed of feed chain 5 from conveyance speed sensor 87, memorizes it in storage part 94, and memorizes time in storage part 94 with reference to timer 91a (Step S5).

  The CPU 91 acquires the loss amount from the loss sensor 34b, stores it in the storage unit 94, and stores the time (hereinafter referred to as discharge time) in the storage unit 94 with reference to the timer 91a (step S6). The CPU 91 determines whether or not the cutting has been completed (step S7). The CPU 91 acquires a signal from the work clutch lever 85 and determines whether or not the work clutch lever 85 is in the “threshing” or “off” position. When the work clutch lever 85 is not in the “threshing” or “off” position, that is, when the cutting is not finished (step S7: NO), the CPU 91 returns the process to step S4.

  When the work clutch lever 85 is in the “threshing” or “off” position, that is, when the cutting is finished (step S7: YES), the CPU 91 moves various data (position information, movement of the tine 3d) stored in the storage unit 94. The speed, the moving speed of the feed chain 5, the amount of loss, and the time) are transmitted to the server 99 via the transmission / reception unit 95 (step S8), and the process ends.

  The control unit 90 may sequentially transmit the position information, the moving speed of the tine 3d, the moving speed of the feed chain 5, the loss amount, and the time acquired in steps S3 to S7 to the server 99.

  Also in steps S4 and S5, as in step S3, the process of associating the tine speed and the chain speed with the time and storing them in the storage unit 94 every time a predetermined time has elapsed may be continuously executed as a subroutine. In this case, when the cutting is not finished (step S7: NO), the CPU 91 returns the process to step S4.

  FIG. 11 is a flowchart for explaining the loss amount mapping process by the server 99. In the storage unit 99d of the server 99, the time required for the threshing of the cereal by the handling cylinder 11 and the selection of the grain by the rocking sorter 16 (hereinafter referred to as the threshing / sorting time), the dimensions of the feed chain 5, and the tine 3d The dimensions of the chain connected to the tine 3d are preset.

  The CPU 99a of the server 99 waits until data is received from the combine (step S11: NO). When data is received from the combine (step S11: YES), the CPU 99a selects one data to be processed from the received data (step S12). The CPU 99a stores the received data in the storage unit 99d.

  The CPU 99a refers to the storage unit 99d and acquires the threshing / sorting time (step S13). The CPU 99a calculates the cereal conveyance time by the feed chain 5 (hereinafter referred to as chain conveyance time) (step S14). For example, the dimension of the feed chain 5 is divided by the moving speed of the feed chain 5 to calculate the chain conveyance time. At this time, even if the time obtained by subtracting the threshing / sorting time from the discharge time (hereinafter referred to as the time immediately before threshing) is calculated, the moving speed of the feed chain 5 corresponding to the time immediately before threshing is obtained, and the obtained moving speed is used. Good.

  The CPU calculates the cereal conveyance time (hereinafter referred to as tine conveyance time) by the tine 3d (step S15). For example, the tine 3d and the dimension of the chain connected to the tine 3d are divided by the moving speed of the tine 3d to calculate the tine conveyance time. At this time, a time obtained by subtracting the threshing / sorting time and the chain transport time from the discharge time (hereinafter referred to as the chain transport previous time) is calculated, and the travel speed of the tine 3d corresponding to the time immediately preceding the chain transport is obtained. May be used.

  CPU99a calculates the time (henceforth a cutting time) when the cereal corresponding to the detected loss amount was cut (step S16). For example, the cutting time is calculated by subtracting the threshing / sorting time, the chain transfer time, and the tine transfer time from the discharge time. The CPU 99a refers to the position of the combine corresponding to the time, and determines the position corresponding to the cutting time (step S17). The CPU 99a sets a loss amount in association with the determined cutting position, and executes loss amount mapping (step S18).

  The CPU 99a determines whether or not the above processing has been performed on all received data (step S19). When the above process is not performed on all received data (step S19: NO), the CPU 99a returns the process to step S12. When the above process is performed on all received data (step S19: YES), the loss amount mapping process is terminated. The CPU 99a stores the result of the loss amount mapping process in the storage unit 99d. A hard disk may be provided, and the loss amount mapping process result may be stored in the hard disk. The server 99 can display a map (loss map) based on the result of the loss amount mapping process on the display screen. For example, the server 99 displays a loss map on the display screen after receiving the display command.

  Examples of the display screen include a display screen provided in a server or a display screen of a terminal (for example, a personal computer) used by a user connected via a network. The CPU 99a may start the loss amount mapping process after receiving the information from the combine and the start command from the user. The CPU 99a may automatically execute the loss amount mapping process after receiving information from the combine.

  FIG. 12 is a diagram illustrating an example of a loss map. FIG. 12 shows the loss amount in each part of the field. The high-density hatching portion indicates that the loss amount exceeds the first reference loss amount, and the low-density hatching portion indicates that the loss amount is not more than the first reference loss amount and not less than the second reference loss amount ( The second reference loss amount <the first reference loss amount) is shown, and a portion without hatching indicates that the loss amount is less than the second reference loss amount.

  By checking the loss map, the user can grasp the distribution state of the loss amount in the field. Therefore, when formulating the next fertilization plan or cropping plan, the user can reflect the distribution of the loss amount in the plan. When the combine is used next time, the user can reflect the distribution of the loss amount in the settings such as the angle of the chaff sheave or the dust feed valve and the air volume of the tang.

  As described above, the moving speeds of the feed chain 5 and the tine 3d may rotate substantially constant or may be changed in synchronization with the vehicle speed (see FIGS. 5 to 8). In Embodiment 1, the moving speed of the feed chain 5 and the tine 3d is detected, and the cutting position is determined based on the detected moving speed. Therefore, the cutting position can be obtained with high accuracy.

(Embodiment 2)
Hereinafter, the present invention will be described based on the drawings showing the mapping system according to the second embodiment. Of the configurations according to the second embodiment, configurations similar to those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. FIG. 13 is a flowchart for explaining input amount data collection / transmission processing by the control unit 90.

  The CPU 91 of the control unit 90 determines whether or not cutting has been started (step S21). The CPU 91 acquires a signal from the work clutch lever 85 and determines whether or not the work clutch lever 85 is in the “cutting” position. When the work clutch lever 85 is not in the “cutting” position, that is, when cutting is not started (step S21: NO), the CPU 91 returns the process to step S21.

  When the work clutch lever 85 is in the “cutting” position, that is, when cutting is started (step S21: YES), the CPU 91 uses the timer 91a to start measuring time (step S22). The CPU 91 continuously acquires the position information of the combine from the artificial satellite 98 via the transmission / reception unit 95, stores it in the storage unit 94, and stores the time in the storage unit 94 with reference to the timer 91a as a subroutine. Execute (Step S23). For example, the CPU 91 stores the combine position information and time in the storage unit 94 in association with the elapse of a predetermined time (for example, every elapse of 0.5 seconds).

  The CPU 91 acquires the moving speed of the tine 3d from the tine speed sensor 88 and stores it in the storage unit 94, and stores the time in the storage unit 94 with reference to the timer 91a (step S24). CPU91 acquires the moving speed of feed chain 5 from conveyance speed sensor 87, memorizes it in storage part 94, and memorizes time in storage part 94 with reference to timer 91a (Step S25).

  The CPU 91 acquires the input amount from the spout sensor 4c, stores it in the storage unit 94, and stores the time (hereinafter referred to as input time) in the storage unit 94 with reference to the timer 91a (step S26). The CPU 91 determines whether or not the cutting has been completed (step S27). The CPU 91 acquires a signal from the work clutch lever 85 and determines whether or not the work clutch lever 85 is in the “threshing” or “off” position. When the work clutch lever 85 is not in the “threshing” or “off” position, that is, when the cutting is not completed (step S27: NO), the CPU 91 returns the process to step S24.

  When the work clutch lever 85 is in the “threshing” or “off” position, that is, when the cutting is finished (step S27: YES), the CPU 91 stores various data (movement speed of the tine 3d, feed) stored in the storage unit 94. The movement speed, input amount, and time) of the chain 5 are transmitted to the server 99 via the transmission / reception unit 95 (step S28), and the process is terminated.

  The control unit 90 may sequentially transmit the moving speed of the tine 3d, the moving speed of the feed chain 5, the input amount, and the time acquired in Steps S23 to S26 to the server 99.

  Also in steps S24 and S25, similarly to step S23, the process of associating the tine speed and the chain speed with the time and storing them in the storage unit 94 may be continuously executed as a subroutine every predetermined time. In this case, when the cutting is not finished (step S27: NO), the CPU 91 returns the process to step S24.

  FIG. 14 is a flowchart for explaining the input amount mapping process and the map composition process by the server 99.

  The CPU 99a of the server 99 waits until data is received from the combine (step S31: NO). When data is received from the combine (step S31: YES), the CPU 99a selects one data to be processed from the received data (step S32).

  The CPU 99a refers to the storage unit 99d and acquires the threshing / sorting time (step S33). The CPU 99a calculates the chain transport time (step S34). For example, the dimension of the feed chain 5 is divided by the moving speed of the feed chain 5 to calculate the chain conveyance time. At this time, the movement speed of the feed chain 5 corresponding to the time immediately before the threshing may be obtained, and the obtained movement speed may be used.

  CPU99a calculates tine conveyance time (step S35). For example, the tine 3d and the dimension of the chain connected to the tine 3d are divided by the moving speed of the tine 3d to calculate the tine conveyance time. At this time, the movement speed of the tine 3d corresponding to the time immediately before the chain conveyance may be obtained, and the obtained movement speed may be used.

  The CPU 99a calculates the cutting time (step S36). For example, the cutting time is calculated by subtracting the threshing / sorting time, the chain transfer time, and the tine transfer time from the discharge time. The CPU 99a refers to the position of the combine corresponding to the time, and determines the position corresponding to the cutting time (step S37). The CPU 99a sets the input amount in association with the determined cutting position, and executes input amount mapping (step S38).

  The CPU 99a determines whether or not the above processing has been performed on all received data (step S39). When the above process is not performed on all received data (step S39: NO), the CPU 99a returns the process to step S32. When the above process is performed on all received data (step S39: YES), the map created by the input amount mapping process (input amount map) and the loss map are combined (step S40), and the process ends. . The CPU 99a stores the results of the input amount mapping process and the map composition process in the storage unit 99d. A hard disk may be provided, and the results of the input amount mapping process and the map composition process may be stored in the hard disk.

  The CPU 99a may start the input amount mapping process and the map composition process after receiving the information from the combine and the start command from the user. The CPU 99a may automatically execute the input amount mapping process and the map composition process after receiving information from the combine.

  The server 99 can display the input amount map on the display screen. For example, the server 99 displays the input amount map on the display screen after receiving the display command. FIG. 15 is a diagram illustrating an example of the input amount map. FIG. 15 shows the input amount in each part of the field. The high density hatched portion indicates that the input amount exceeds the first reference input amount, and the low density hatched portion indicates that the input amount is equal to or less than the first reference input amount and equal to or greater than the second reference input amount ( The second reference input amount <the first reference input amount) is shown, and the portion without hatching indicates that the input amount is less than the second reference input amount.

  The server 99 can combine the input amount map and the loss map, and display the combined map (composite map) on the display screen. For example, the server 99 displays the composite map on the display screen after receiving the display command. FIG. 16 is a diagram illustrating an example of a composite map. For example, in the composite map, it is considered that the amount of grain discharged from the combine without being harvested is large in the portion where the loss amount is the first reference loss amount and the input amount is the first reference input amount or more. . Therefore, when the user cuts the portion next time, the user adjusts the angle of the combine chaff sheave 18 or the dust feed valve 13a or adjusts the air volume of the tang 27, and inputs more grains into the grain tank 4. The settings can be changed as required.

  For example, in the composite map, it is considered that there is much lodging of the cereal for the portion where the loss amount is equal to or greater than the first reference loss amount and the input amount is less than the second reference input amount. When there is much lodging, it is thought that the posture or state of the cereal conveyed to the threshing device 2 is disturbed, and as a result, the amount of kernel discharged from the combine increases.

  For example, if fertilization is excessively performed at the time when the portion between the 4th and 5th nodes of rice grows, the probability of lodging will increase. Therefore, the user can take measures such as performing fertilization at different times without applying fertilization at the time when the above-described field portion is easy to fall down.

  When the user confirms the composite map and formulates the next fertilization plan or cropping plan, the user can reflect the distribution of the loss amount and the input amount in the plan. When the combine is used next time, the user can reflect the distribution of the loss amount and the input amount in the settings such as the angle of the chaff sheave 18 or the dust feed valve 13a and the air volume of the tang 27.

  In the embodiment described above, the detection value of the loss sensor 34b is used, but the detection value of the loss sensor 34a may be used instead. In this case, the detection value of the loss sensor 34a is input to the control unit 90 via the input I / F 96.

  The detection amount of the loss sensor 34a easily reflects the results of threshing by the handling cylinder 11 and the processing cylinder 13b, and has a high correlation with the threshing property (ease of threshing) of the cereal. On the other hand, the loss sensor 34b has a high correlation with the ease of selection based on the amount of cereal leaves. These vary depending on the characteristics of the rice.

  Therefore, when a loss map based on the detection amount of the loss sensor 34a is created, the user mainly adjusts the dust delivery valve 13a. On the other hand, when the loss map based on the detection amount of the loss sensor 34b is created, the user mainly adjusts the angle of the chaff sheave 18 or the air volume of the tang 27.

  Alternatively, the detection amounts of the loss sensor 34a and the loss sensor 34b may be detected, and a loss map may be created based on the two detection amounts. By creating two loss maps, more accurate settings can be made. Also, each of the two loss maps and the input amount map may be combined.

To do. Steps S21 to S27 are executed, and the moving speed of the tine 3d, the moving speed of the feed chain 5, the input amount, and the time (hereinafter, these data are referred to as a second data group) are stored in the storage unit 94.

  The CPU 99a of the server 99 determines whether or not the first data group has been acquired, and executes the loss amount mapping process when the first data group has been acquired (see FIG. 11). Here, in the loss amount mapping process, the process in step S11 is read as to whether or not the first data group has been acquired. That is, the CPU 99a waits until the first data group is acquired (step S11: NO), and when the first data group is acquired (step S11: YES), the process proceeds to step S12.

  The CPU 99a determines whether or not the second data group has been acquired. If the second data group has been acquired, the CPU 99a executes the input amount mapping process and the map composition process (see FIG. 14). Here, in the input amount mapping process and the map composition process, the process in step S31 is read as to whether or not the second data group has been acquired. That is, the CPU 99a waits until the second data group is acquired (step S31: NO), and when the second data group is acquired (step S31: YES), the process proceeds to step S32.
