Japanese Patent Laying-Open No. 2004-275040 (FIG. 7)

The amount of grain differs greatly from each other due to the difference in specific gravity among the varieties, and the bulk height varies depending on the water content even in the same varieties. With the grain sensor of the Glen tank described in the above-mentioned patent document, it is impossible to detect the amount of grain due to the difference in grain varieties and the difference in water content.
The subject of this invention is providing the combine provided with the grain tank which can detect the storage amount of a grain correctly more than before.

The above-mentioned subject is achieved by adopting the following solution means.
According to the first aspect of the present invention, in the combine provided with the Glen tank (30) for temporarily storing the harvested crop, the weight detecting means (47) for detecting the weight of the crop at the bottom of the Glen tank (30). And a crop detection means (49) for detecting the presence of the crop in the middle part of the Glen tank (30), and a weight detection means when the crop detection means (49) detects the presence of the crop. The combine is provided with a crop type discriminating means (23) for discriminating the type of the crop based on the weight of the crop according to (47).

According to the second aspect of the present invention, the moisture detection means (48) for detecting the moisture value of the harvest is provided in the middle part of the Glen tank (30), and the harvest type discriminating means (23) is the crop detection means (49). 2) the type of the crop is determined based on the weight of the crop by the weight detection means (47) at the time when the presence of the crop is detected and the moisture value by the moisture detection means (48). It is the described combine.
According to the first aspect of the present invention, when the moisture content of the crop (grain) is not measured, the crop detection sensor is first stored during the storage of the crop (grain) in the Glen tank (30). Which of the crops the relationship between the weight and the volume is known in advance from the weight of the crop by the weight sensor (47) at the time when (49) detects the presence of the crop. Can be judged. Therefore, when the Glen tank (30) is first filled and the full harvest is discharged from the Glen tank (30), when the second storage in the Glen tank (30) is performed, The storage operation is continued assuming that the type of crop determined by the determination is being stored in the Glen tank (30).

  According to the first aspect of the present invention, the harvest type discriminating means (23) determines the weight of the harvest by the weight detection means (47) when the harvest detection means (49) detects the presence of the harvest. Based on the weight, the type of the harvest (for example, whether the grain is rice or wheat) is discriminated, so that the operating conditions of the threshing device can be in a state suitable for each harvest. Sorting performance is improved.

  According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, when the difference in the type cannot be determined only by the weight of the harvested product, a more accurate harvest can be performed from the relationship between the moisture value and the weight. Automatic identification of objects becomes possible.

Embodiments of the present invention will be described with reference to the drawings.

It is conveyed to the Glen tank 30 through the cerealing cylinder 16 and is temporarily stored in the Glen tank 30.

  The remaining threshed culms that have reached the end of the handling chamber 66 of the threshing device 15 and are kept in a long length are sandwiched and conveyed by the culling chain 80 and the culling head chain 81, and the rear portion of the threshing device 15. Is inserted into a culvert cutter in a sterilization treatment chamber (not shown), cut and released to the field.

  A grain tank spiral 32 (FIG. 3) for transferring grains is provided at the bottom of the grain tank 30, and a discharge auger comprising a vertical auger 18 and a horizontal auger 19 on a spiral drive shaft (not shown) for driving the grain tank spiral 32. And the grains stored in the Glen tank 30 are discharged from the discharge auger outlet to the outside of the combine. The Glen tank spiral 32, the vertical auger spiral (not shown), and the horizontal auger spiral (not shown) are driven to rotate by the power transmitted from the engine 8 (FIG. 3), and by the screw conveyor action of each spiral blade. Transports stored grain.

  The grain husks harvested by the reaping device 6 are adjusted in the handling depth by the cereal conveyance and adjusting device attached to the reaping device 6 and inserted into the handling chamber 66 which is the main threshing portion of the threshing device 15. A handling drum 69 pivoted in the handling chamber 66 is provided with a large number of teeth 69a on the surface thereof, and rotates in the direction of arrow B1 in FIG.

  Grains with grains inserted in the handling chamber 66 are transferred in the direction of arrow A in FIG. 2 by the moving feed chain 14, while handling teeth 69 a and handling nets 74 of the handling drum 69 rotating in the direction of arrow B 1. Is threshed by the interaction. The object to be processed (grains and sawdust) separated from the cereals passes through the handling net 74 in the direction of arrow C1 (FIG. 2) and is received by the swing sorting shelf 51.

  The swing sorting shelf 51 is arranged at the uppermost transfer shelf 55 and the lower transfer shelf 56 arranged below the handling net 74 of the handling chamber 66, the upper sheave 53 arranged behind it, the sorting net 63 below and the rearmost end. The Strollac 62 is made up of.

  The upper and lower two-stage transfer shelves 55 and 56 are respectively provided with a plurality of triangular sorting plates 55a and 56a. The upper transfer shelf 55 is disposed in front of the sheave 53, and the lower transfer shelf 56 is disposed in front of the sorting net 63. Further, the lower transfer shelf 56 is longer than the upper transfer shelf 55 on the front side of the threshing device 15 so that a recovery port for recovering the workpiece leaking from the handling chamber 66 is opened above the upper transfer shelf 55. Arrange so that

  Further, since the swing sorting shelf 51 swings in the up / down and front / rear direction by the operation of the swing sorting shelf drive mechanism (not shown), the specific gravity which has been leaked onto the lower transfer shelf 56 while moving in the direction of arrow D. The heavier grain passes through the sorting net 63 in the direction of arrow E, is accumulated on the first shelf 64, and is conveyed from the first spiral 65 to the grain tank 30 through the milled cylinder 16. The grain stored in the Glen tank 30 is conveyed to the outside of the combine via the augers 18 and 19.

  Among the objects to be processed that have fallen from the dust collection chamber 68 through the dust collection cylinder 71 as indicated by the arrow M to the terminal end of the swing sorting shelf 51 from the second dust collection cylinder 72, the lighter one is the rocking sorter. The swinging action of the shelf 51 and the air blown by the fan 79a of the tongue 79 move in the direction of arrow D from the upper transfer shelf 55 toward the sheave 53, and the second small grain on the Strollac 62 is It leaks in the direction of the arrow G and is collected on the second shelf 85 and conveyed to the second lifting cylinder 87 by the second spiral 86.

  In the present embodiment, a dust removal processing cylinder 71 having a spiral 71 a is disposed behind the handling cylinder 69 of the handling chamber 66 (reverse direction of the combine), and a second dust disposal cylinder 72 is disposed below the dust processing cylinder 71. In the example shown, the filtered matter filtered from the dust exhausting cylinder 71 is guided onto the second dust exhausting cylinder 72 by a guide plate 73 provided on the side of the second dust exhausting cylinder 72 and dropped. Then, it is collected on the swing sorting shelf 51 by the spiral 72a.

  With the above-described configuration, the second dust discharge treatment is performed without dropping the filtered matter filtered from the dust removal processing cylinder 71 on the swing sorting shelf 51 prior to the secondary sorting by the swing sorting shelf 51 and the Karatsu 79 described later. The cylinder 72 can be efficiently recovered, and the filtrate can be recovered in front of the swing sorting shelf 51 by the second dust removal processing cylinder 72, so that the threshing accuracy is improved.

  The combine of the present embodiment is a combine in which the Glen tank 30 can be opened and closed as shown in FIG. 3. If the engine 8 remains driven when the Glen tank 30 is opened, the Glen tank 30 that operates by driving the engine 8 is used. Since the driving belt 42 of the helix 32 for threshing of the cereals is still in operation and the operator can approach a portion of the helix driving belt 42 when the glen tank 30 is opened, it is dangerous.

Therefore, the following configuration can be adopted so that the driving of the engine 8 is always stopped when the Glen tank 30 is opened.
That is, as shown in the schematic plan view including the drive system of the Glen tank 30 in FIG. 3, a cover 45 is provided around the drive belt 42 of the spiral helix 32 for auger mashing, and the cover 45 is not opened. The Glen tank 30 cannot be opened, and when the cover 45 is further opened, the limit switch 44 is turned off and the engine 8 is stopped.
Thus, when the glen tank 30 is opened, it is necessary to open the cover 45 covering the belt 42. When the belt 42 is removed, the engine 8 is automatically stopped and safety is increased.

Further, as shown in a side view showing a part of the inside of the Glen tank 30 shown in FIG. 4, the Glen tank 30 of the present embodiment discriminates the kind of the harvest in the Glen tank 30 by weight or by weight and moisture value. can do.
A full sensor 46 is provided on the upper wall surface inside the Glen tank 30, and one crop detection sensor 49 and one moisture meter 48 are provided on the inner wall surface of the intermediate tank, and a weight sensor 47 is provided at the bottom inside the Glen tank 30. Is provided.
The measured value of the moisture meter 48 is the moisture content (%). The moisture meter 48 extracts one grain (harvest) and crushes it with a roller to determine the moisture content in the grain. It is a value obtained by measuring.
The crop detection sensor 49 determines that the crop is present when the crop enters the box to which the sensor 49 is attached and touches the sensor.

Further, as shown in the control block diagram of FIG. 5, when the full sensor 46 detects the grain, the buzzer 52 sounds, and the operator can stop the introduction of the grain into the glen tank 30.
Further, instead of the buzzer 52 or at the same time, the detection results of the sensors 46 to 49 in the Glen tank 30 can be displayed on the panel of the operation seat 20 with a display lamp or a character display.

FIG. 6 shows the relationship between the moisture content (%) and the harvest weight (specific gravity) relative to the unit harvest weight when the harvest is wheat and rice.
Therefore, when the moisture content is not measured, the volume and yield of the crop that are measured in advance based on the weight when the moisture content (%) is zero, that is, the measured values of the crop detection sensor 49 and the weight sensor 47, respectively. From the relationship with the weight of the product, it can be determined whether the harvest stored in the Glen tank 30 is wheat or rice.

Further, in the unknown zone Z in which it is unknown whether the harvest is wheat or rice shown in FIG. 6, the water content is measured and stored in the Glen tank 30 from the relationship between the water content (%) and the weight in FIG. 6. It is possible to determine whether the harvest being harvested is wheat or rice.
A series of these crop determination methods is shown in the flowchart of FIG.

  In addition, when the moisture content of the harvest is not measured, the weight sensor at the time when the harvest detection sensor 49 detects the presence of the harvest first during the storage of the harvest (grain) in the Glen tank 30. 47, it is possible to determine which one of the types of crops whose weight-capacity relationship is known in advance, but first the Glen tank 30 becomes full, After discharging the full crop from the glen tank 30, when storing in the glen tank 30 for the second time, it is assumed that the type of crop determined by the above determination is being stored in the glen tank 30. To continue.

The threshing conditions can be changed, for example, as follows depending on the type of the harvest.
That is, when the harvest is wheat, the handling cylinder rotation speed changing means 58 lowers the rotation speed of the handling cylinder 69 as compared to the case of rice, thereby preventing detachment. Moreover, since wheat straw generates a relatively large amount of straw waste when threshing, the rotation speed of the red pepper 79 is made faster than the case of rice by the red pepper rotation speed changing means 59 to improve the sorting performance.

  As shown in FIG. 8 (b), which is a power transmission diagram of FIG. 8 (a) and an arrow view from the direction of arrow A in FIG. 8 (a), there is a metal portion 90 at the rear of the Glen tank 30 of this embodiment. A drive transmission device 94 comprising pulleys or sprockets 91 and 92 and a belt or chain 93 is provided on a bearing portion around the axial center of the vertical auger 18 at the connection portion to the vertical auger 18. A drive shaft 95 for transmitting power to the section 90 is provided below the Glen tank bottom plate, a cam 96 is provided on the drive shaft 95, and a vibration device 57 (FIG. 9) for the Glen tank bottom plate is provided via a gear 57a. It is configured to be driven.

  If the grain tank 30 is clogged with the grain tank 30 or the augers 18 and 19 when the grain is discharged, a large amount of work is required to eliminate the grain clogging. Although the flow rate can be adjusted by the Glen tank spiral cover 27 (FIG. 11) inside the Glen tank 30, the operator enters the inside from the upper part of the tank 30 for maintenance or removes many bolts on the side plate, Since there is only a way to work with the inside of the door open, the work was difficult. In addition, the bottom plate provided with the vibration device 57 has a problem that the effect of vibration is weak because the periphery is welded to form an integral structure.

  Therefore, in the present embodiment, as shown in FIG. 9, the Glen tank bottom plate is composed of a frame portion 30 a provided integrally with the Glen tank 30 and a lid portion 30 b provided over substantially the entire surface including the vibration device 57. Normally, the outer periphery of the lid portion 30b is provided so as to be in close contact with the bottom plate frame portion 30a, and during internal maintenance (such as when adjusting the flow rate adjusting plate), it can be rotated and opened upward in the Glen tank. I made it.

  In addition, a hinge 30c is provided at the upper part of the lid part 30b, and the lower part of the lid part 30b is configured to be locked by a plurality of locking devices 30d and 30d, and also on the inner wall surface facing the lid part 30b in the tank. The members 30e and 30e with which the locking device of the lid portion 30b is engaged are provided, and the lid portion 30b of the Glen tank bottom plate can be fixed freely in either state.

Thus, maintenance of the adjustment plate (not shown) inside the Glen tank 30 and internal cleaning becomes very easy.
Further, it is possible to prevent accidents during work such as the lid 30b that is lifted upward automatically, and at the same time to use parts in common, thereby reducing costs and improving maintainability.

Conventionally, when the grain is discharged from the glen tank 30 to the vertical auger 18, there are the following problems.
That is, as soon as the idling operation of the engine 8 is started and the discharge clutch switch 21 shown in FIG. 3 is turned on, the discharge clutch operating motor 22 is operated and the grain is discharged from the glen tank 30. At this time, when the operator suddenly operates the throttle lever (not shown) to the full throttle, the rotational speed of the engine 8 tends to increase rapidly, but the grains exist around the spiral 32 of the Glen tank 30 at a high concentration. In such a case, the torque of the spiral shaft 24 may increase abnormally, and the discharge bevel gear 25 and the like may be damaged.

  Therefore, in this embodiment, as shown in FIG. 3, the engine power is transmitted through the grain discharge clutch switch 21 to drive the Glen tank spiral 32 and the spirals (not shown) in the augers 18 and 19. These spiral driving procedures are performed as follows.

  First, idling rotation of the engine 8 is started, and then the discharge clutch switch 21 for driving the discharge clutch is turned on to operate the discharge clutch operating motor 22. At this time, the discharge clutch operating motor 22 is set not to operate while the rotation of the engine 8 does not reach the rated speed. This is to prevent rotation of the Glen tank spiral 32 and the like unless engine power sufficient to discharge the grains is obtained.

  When the operator operates the throttle lever and the engine speed reaches the rated speed, an engine speed sensor 26 (not shown) detects the engine speed and transmits it to the CPU 23, and the CPU 23 starts the operation of the discharge clutch operating motor 22. Thus, the grains in the Glen tank 30 are discharged from the augers 18 and 19 to the outside (such as a truck bed). As described above, the grain discharge is performed only in the zone of the rated rotational speed of the engine 8.

  Further, when the grain discharge by the Glen tank spiral 32 or the like is started, the discharge is started after the engine 8 is stabilized at the rated rotation, so that the torque of the spiral shaft 24 or the like does not fluctuate and the bevel gear 25 can be prevented from being damaged.

Further, a configuration using a discharge clutch lever 33 shown in FIG. 10 in place of the discharge clutch switch 21 for driving the discharge clutch may be adopted. The procedure in this case is performed as follows. First, after setting the engine rotation to the idling state, the discharge clutch lever 33 is inserted. When the discharge clutch lever 33 is inserted, a discharge clutch lever switch 36 (not shown) installed at the rotation base of the lever 33 is turned on. The on-state of the switch 36 is transmitted to the CPU 23, and the CPU 23 operates the accelerator motor 34 shown in FIG. 10 having a function of gradually operating the throttle lever to raise the engine 8 to the rated speed.
Therefore, even when the grains are present in a high concentration around the Glen tank spiral 32 of the Glen tank 30, the torque of the Glen tank spiral shaft 24 does not increase, and the discharge bevel gear 25 and the like may be damaged. There is no.

Next, the structure regarding prevention of grain discharge clogging from the grain tank 30 of the present embodiment will be described.
Conventionally, when the discharge augers 18 and 19 of the glen tank 30 are clogged, the glen tank spiral cover 27 in the glen tank 30 is removed as shown in FIG. Since the cover 27 is taken out and the amount of protrusion of the auxiliary cover 27 ′ supporting the cover 27 is adjusted, and then the spiral cover 27 is attached to the auxiliary cover 27 ′ again, these adjustments require a lot of man-hours. It was.

  Therefore, in this embodiment, as shown in a side sectional view of the tank bottom in FIG. 11A and a view taken along the line AA in FIG. 11A shown in FIG. The spiral cover 27 is arranged on the outer circumference of the Glen tank spiral 32 so as to be rotatable by 180 degrees, and slits 27a and 27b through which the grains pass are provided symmetrically with respect to the axis of the cylindrical spiral cover 27. . Also, as shown in FIG. 11 (b), the intervals α and β between the slits 27a and 27b on the circumference of the cylindrical spiral cover 27 are set to different sizes so that the gap between the bottom wall of the Glen tank 30 is set. Adjustable. Therefore, the amount of grain carried to the Glen tank spiral 32 can be changed depending on whether the wide side or the narrow side is arranged on the upper side.

As shown in the perspective view seen from the direction of arrow B in FIG. 11A shown in FIG. 11C, the spiral cover 27 is rotated from the outside of the tank 30 by operating the bolt 31 protruding outside the tank 30. Can be moved.
A seal 29 is provided at the end of the spiral cover 27, and a bolt 31 is attached to the seal 29 so as to penetrate the wall surface of the tank 30 and protrude outside. The portion of the bolt 31 protruding outward from the side wall of the glen tank is manually operated to move within the arc-shaped gap provided on the wall surface of the tank 30 so that the cover 27 integrated with the bolt 31 can be rotated. . After rotating the cover 27, the bolt 31 is fixed to the side wall of the glen tank 30 by the nut 35. The seal 29 is provided so as to contact the inside of the side wall of the tank 30 in order to prevent the grains from leaking from the gaps in the side wall of the tank 30 where the bolt 31 moves.

As described above, since the spiral cover 27 can be manually rotated from the outside of the grain tank 30, the grain discharge amount from the grain tank 30 can be easily adjusted by changing the arrangement positions of the slits 27a and 27b. As shown in the side view of the inside of the grain tank 30 in FIG. 12 (d), the grain supplied from the grain mill 16 into the conventional grain tank 30 is the grain mill outlet on the side wall of the grain tank 30. It flows into the Glen tank 30 from 16a and accumulates in a mountain shape in the Glen tank 30. Therefore, the grain filling amount when the grain in the Glen tank 30 is full is smaller than the tank capacity.

  Therefore, in this embodiment, the Glen tank 30 and the vertical auger 18 in FIG. 12 (a) are partially side views inside, and FIG. 12 (b) is a view from the arrow A direction in FIG. 12 (c), which is a plan view of the interior of 30, an inclined portion 28a having a gap between the side surface of the grain tank 30 at the lower portion of the milled cylinder kernel outlet 16a in the grain tank 30 is provided. It was set as the structure which provides the grain flow board 28 which has.

  Since a gap is provided between the side surface of the grain tank 30 and the grain flow plate 28, the grains can be sequentially filled from the inclined portion 28 a of the grain flow plate 28 toward the side wall surface of the grain tank 30. In the tank 30, the height of the mountain-shaped mountain of grains is lowered. Thus, the grain filling amount in the Glen tank 30 becomes larger than before.

  Further, by using the shape of the side wall surface of the Glen tank 30 obtained by blow molding as shown in FIG. 13A, the protruding portion 30f of the side wall surface of the Glen tank 30 has a function of an auger receiver. Compared with the case where the auger receiver 100, which is an independent part shown in 13 (b), is attached to the glen tank 30 or the threshing device case, weight reduction and cost reduction can be achieved. Moreover, the capacity | capacitance of the Glen tank 30 can also be expanded with such a structure.

  The threshing apparatus of the present invention can be used in a harvested grain processing apparatus such as a combine.
