Description

  The present invention relates to a combine that accommodates the supply position of a grain discharged from a discharge unit with restriction guidance.

Conventionally, when harvesting heavy grains such as wet rice cakes, a combine that prevents unbalance due to excessive unbalanced loading of the Glen tank and ensures a stable traveling condition is already known. (For example, patent document 1).
The combine is disposed behind the control unit on the other side of the threshing unit mounted on one side of the traveling machine base including the preprocessing unit, and accommodates and guides the grain supplied from the threshing unit (hereinafter referred to as the inner wall plate). The guide plate) is shaped along the outer wall (hereinafter referred to as the right side wall) of the Glen tank, and the lower part is pivotally supported so as to be tiltable inward.
JP 2004-305124 A

The Glen tank shown by the above-mentioned patent document 1 is discharged from the discharge part of an elevator (flouring cylinder) by tilting the guide plate to the inner side wall (hereinafter referred to as the left side wall) side in the initial state of performing the combine operation. The grain center is stored in a limited amount on the left side wall, and the center of gravity of the Glen tank as a whole is moved to a lower position near the center of the fuselage. There is an advantage of ensuring driving conditions.
However, since the above-mentioned Glen tank is provided with a guide plate having the same weight as the right side wall of the Glen tank, there is a drawback that the guide plate increases the weight of the Glen tank and raises the position of the center of gravity. Further, since the guide plate is rotated about the lower support shaft, there are disadvantages in that the rotation support and rotation drive structure of the guide plate is complicated, the size is increased, and the cost is increased.
The Glen tank, when the aircraft detects that there is no grain at a predetermined ascending position, tilts the guide plate to the tilted position and stores the grain in a limited manner. After storing, since there is no means to automatically drive the guide plate in the anti-tilt (stand-up) direction according to the amount of grain, it is necessary to frequently discharge the grain during combine work, There is a problem that a special full operation means is required to fill the grain.

  In order to solve the above-mentioned problem, the combine of the present invention is as follows. First, the threshing unit 5 installed on one side of the traveling machine base 1b is transferred from the threshing unit 5 to the other side of the Glen tank 2, and the grain from the discharge unit 60 of the milling cylinder 59 In the combine which discharges and stores grains, the grain tank 2 is provided with a guide member 62 for switching the storage position of the grains, and grain detection sensors 67, 68 and 69 for detecting the storage amount, and the grain detection sensor A storage position control means having an actuator 65a for controlling the operation of the guide member 62 according to the detected values 67, 68, 69 is provided. The storage position control means is provided inside the glen tank 2 by the guide member 62 as the storage amount increases. The storage position is switched from the outside to the outside.

  Second, the guide plate 62 is mounted on and supported by the upper portion of the Glen tank 2 so as to face the discharge portion 60.

The combine according to the present invention has the following effects. The guide member that guides the storage position of the grain in the grain tank is operated by the actuator via the storage position control means according to the detection value of the grain detection sensor, and from the inside of the grain tank to the outside as the storage amount increases. By switching the storage position, the storage position of the grain discharged from the discharge unit of the whipping cylinder is moved from the inner side of the grain tank to the outer side, so the center of gravity position of the grain tank can be changed easily. In addition, the grain can be sufficiently accommodated while running with good stability.

  The guide member that is pivotally mounted and supported at the upper part of the Glen tank prevents the scattering of the grain discharged from the discharge part, and guides the regulation downward, ensuring the supply direction of the grain. And can be stored. Also, the guide member that rotates on the fulcrum facing the discharge part is a flat plate that can be reduced in size and weight, and without increasing the weight of the glen tank, the adjustment drive part can also have a simple structure. it can.

  An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a combine equipped with a Glen tank 2 according to the present invention. This combine 1 arrange | positions working parts, such as the pre-processing part 3, the threshing part 5, and the waste cutting part 6, in the front-back direction like the conventional one on the traveling machine stand 1b provided with the crawler traveling apparatus 1a, On the right side of the platform 1b, the control unit 7, the engine 8 and the Glen tank 2 are arranged in the front-rear direction.

  As shown in FIG. 3, the traveling machine base 1b of the combine 1 has a plurality of leg portions formed by bending a round pipe material into a square shape around the lower part of the machine body frame 9 formed in a square shape in plan view. The frame 10 is attached and fixed, and the left and right track frames 11 are integrally attached and fixed to both ends of each leg frame 10 arranged at the front and rear. The track frame 11 is provided with an upper roller 12 at the upper part of the frame housing, a plurality of lower wheels 13 at the lower part, and a driven wheel 15 at the rear end. Then, an endless belt-like crawler 16 is wound around the driving wheel 18 pivotally supported by the transmission case 17 at the front of the traveling machine base 1b, the upper rolling wheel 12, the plurality of lower rolling wheels 13, and the driven wheel 15. The apparatus 1a is configured.

  Moreover, the adhesion prevention member 19 which prevents adhesion of scattered debris, adhesion of mud, etc. is constructed in the outer peripheral surface of the leg part frame 10 of the crawler traveling apparatus 1a. The adhesion preventing member 19 is a sliding or water-repellent seal-like member or coating member, so that the scraps and mud that are in contact with and adhere to the surface of the leg frame 10 are quickly slid down. Accumulation of deposits on the part frame 10 can be suppressed.

As shown in FIGS. 3 to 5, the lower roller 13 is connected to a roller shaft 20 that is detachably attached to the track frame 11, and a pair of left and right outer wheels 21 and an inner wheel 22 are interposed via a boss portion 20 a. It is configured to be pivotally supported. A plurality of mud removing plates 23 are provided in opposing positions in the saddle-shaped recess of the outer roller 21.
The mud removing plate 23 is made of a spring plate, has a length that is fixedly mounted in the outer roller 21 and protrudes in the vicinity of the outer side of the crawler 16, and advances (advances) the plate mounting angle with respect to the rotational axis in plan view. A predetermined receding angle is provided in the direction.

  As a result, when the combine 1 moves forward, the mud that adheres and moves while riding on the inner peripheral surface of the crawler 16 is brought into contact with the plurality of mud removing plates 23 of the lower roller 11, and the receding angle of the mud removing plate 23. Can be sequentially moved outward and discharged sequentially from the inner peripheral surface. Therefore, since mud adhering to the inner peripheral surface of the crawler traveling device 1a is sequentially discharged without growing into a large clot, when the headland cereal reaping operation is performed like a conventional crawler traveling device, it is large. Without causing the earth clumps to fall to the uncut grain side of the headland, it is possible to prevent the grains from being raised or poorly cut, and the cutting blades to be worn at an early stage.

  Further, as shown in FIG. 2, the combine 1 guides the soil lump that guides the soil lump discharged from the crawler 16 toward the inside of the track of the crawler 16 at the rear left side of the body frame 9 on the headland cutting work side. A plate 25 is provided. The earth lump guide plate 25 forms a guide plate portion 26 along the outside of the crawler 16 and a dirt-feeding portion 27 in which the rear portion is bent toward the rear portion width of the crawler 16. The upper portion of the guide plate portion 25 is connected and supported via a plurality of support links 29 and 29 that form parallel links with the body frame 9.

  When the headland cutting operation is performed with this configuration, the combine 1 is supported by the support links 29 and 29 as shown in the solid line of FIG. Drive while letting. As a result, the soil lump guide plate 25 collects and guides the lump released from the crawler 16 to the ground by the guide plate portion 26, and can be brought into the trace of the crawler 16 by the back litter portion 27. Prevent the release of clumps to the side of the stock of straw. When the combine 1 moves backward, the lump guiding plate 25 can be automatically raised through the support links 29 and 29 as shown by the dotted line in cooperation with the reverse operation.

Further, as shown in FIG. 3, the engine 8 is mounted and supported horizontally on a plurality of support portions formed on the body frame 9 via vibration-proof rubber 30, and a radiator 31 is erected on the right side frame of the body frame 9. ing.
In the above configuration, the muffler 32 of the engine 8 is attached and fixed to the lower part of the space formed by the engine body 33 and the radiator 31 by the attachment bracket 35 formed on the body frame 9. The muffler 32 is connected from the exhaust part of the engine 8 via the flexible tube 36 and is provided so that the open end of the exhaust pipe 37 is exhausted rearward.

  The muffler 32 attached as described above is attached and supported on the body frame 9 side without being directly attached to the engine body 33 as in the conventional case, and is connected by the flexible tube 36, so that the engine vibration is directly applied to the muffler 32. In addition, there is a feature that it can be installed compactly and stably between the engine body 33 and the radiator 31.

Next, the glen tank 2 will be described with reference to FIGS. The Glen tank 2 is mounted on the body frame 9 on the right side of the threshing portion 5 in the rear view, and has the same structure as that of the conventional tank frame walls, ie, a front side wall 50, a rear side wall 51, a left side wall 52, and a right side wall 53. And a tank having a funnel-shaped bottom wall 55, 56 at the bottom of the tank frame wall and a ceiling wall 57 at the top.
In addition, the Glen tank 2 faces the discharge part 60 of the whipping cylinder 59 of the threshing part 5 at the upper part of the left side wall 52, and faces the valley part formed in a funnel shape at the bottom walls 55 and 56 toward the rear. A grain horizontal feed spiral 61 for transferring the grain is pivotally supported, and the grain is continuously transferred from its end to a vertical discharge auger (grain vertical feed cylinder) 70a of a grain discharge auger device 70 described later. .

As shown in FIG. 6, the Glen tank 2 is provided with a guide plate (guide member) 62 for guiding the storage position of the grains discharged from the discharge unit 60 at a position facing the discharge unit 60, and this guide plate. 62 is provided close to the left side position from the center of the Glen tank width.
And the guide plate 62 is equipped with the grain supply position adjustment means which can determine automatically the supply position (storage position) of the discharge grain discharged and supplied from the discharge part 60. FIG.

That is, the Glen tank 2 according to the embodiment has the guide plate 62 close to and opposed to the discharge unit 60 with a distance of about one third of the left and right width, and via the support shaft 63 provided on the ceiling wall 57. It is configured to be connected to an operating rod 66 of an adjustment driving unit 65 that is rotatably supported and is mounted and supported on the upper portion of the left side wall 52.
And the grain detection sensor 67,68,69 is provided in the up-down direction inside the left side wall 52 with a predetermined space | interval. The grain detection sensors 67, 68, 69 input detection signals corresponding to the grain detection state to a storage position control means (control box) that controls the drive motor (actuator) 65a of the adjustment drive unit 65, The operation of the guide plate 62 can be controlled by rotating the support shaft 63 about the fulcrum by the storage position control means.

The adjustment drive unit 65 includes a drive motor 65a that is controlled to rotate forward and backward by signals from the grain detection sensors 67, 68, and 69, and an operating rod 66 that includes a screw rod that moves forward and backward by the rotation of the drive motor 65a. The operating rod 66 and the guide plate 62 are connected via a universal joint 71.
With this configuration, the drive motor 65a moves the guide plate 62 through the actuating rod 66 and the universal joint portion 71, the initial housing posture A in the suspended state indicated by the solid line, the intermediate housing posture B in the rotationally inclined state indicated by the dotted line, and the It is possible to switch to the full accommodation posture C in the upward rotation state.

Thereby, the guide plate 62 regulates and guides the grains discharged from the discharge section 60 at each posture position, and the initial storage amount A1 and the intermediate storage as shown by the dotted line in FIG. It can be stored to form a quantity B1 and a full capacity C1.
Further, the guide plate 62 is a flat plate having a size for receiving the grains discharged from the discharge unit 60, and is discharged from the discharge unit 60 by the rotation of the discharge blade 72 provided at the upper end of the whipping spiral shaft in the whipping tube 59. The grain can be regulated and stored, and the supply direction can be reliably determined and stored.
In addition, when the grain supply position adjustment is not controlled as described above, the guide plate 62 can maintain the stop posture beyond the full storage posture C position. Further, it is desirable that the guide plate 62 and the grain detection sensors 67, 68, 69, etc. be detachable from the Glen tank 2.

  The Glen tank 2 having the above-described configuration is formed such that the guide plate 62 is sized to prevent the grain discharged from the discharge unit 60 from scattering and to guide the regulation downward, and is rotatable to the top of the Glen tank 2. Therefore, it is possible to change the position of the grain storage amount corresponding to the discharge unit 60 without rotating by providing a large partition wall equivalent to the right side wall 53 in the grain tank 2 as in the conventional case. Since it can be performed only by rotating the formed small and light guide plate 62, the weight of the Glen tank 2 is not increased so much, and the adjustment drive unit 65 can also have a simple lightweight structure. There is.

The guide plate 62 is not limited to the rotation adjustment method as described above, but the adjustment drive unit can be adjusted by adjusting the guide plate 62 in the horizontal direction with respect to the discharge unit 60 or by a non-contact type grain detection sensor. 65 can be controlled.
Moreover, the grain discharge auger device 70 installed at the rear part of the Glen tank 2 includes a vertical discharge auger 70a erected at the rear part of the Glen tank 2 and a relay operating mechanism (grains) configured at the upper part of the vertical discharge auger 70a. And a known structure such as a grain discharge auger (grain horizontal feed cylinder) 75 which is mounted and supported by the relay actuating mechanism 73 so as to be turned up and down and has a grain discharge port 74 at the tip. .

The combine 1 configured as described above conveys and supplies the cereals harvested by the pretreatment unit 3 to the threshing unit 5 to perform threshing, accommodates the threshed and selected grains in the glen tank 2, and has been threshed. This waste is sent to the waste cutting section 6 for cutting processing and discharged outside the machine to perform a series of combine operations.
In addition, the grain discharging auger device 70 can be discharged in the state where the operator stops the machine and stops the grain discharging auger 71 in the retracted position to the grain discharging position. Drive. Thereby, the grain in the grain tank 2 is discharged from the grain discharge port 74 of the grain discharge auger 71 and stored in a grain bag (not shown) prepared on the ground or a truck waiting on the road.

In the combine operation as described above, the grain detection sensors 67 and 68 are initially in the harvesting operation.
, 69 detect the empty state of the Glen tank 2, so that the guide plate 62 is set to the initial accommodation posture A as shown in FIG. 6, whereby the grains discharged from the discharge unit 60 hit the guide plate 62. Regulation guidance is provided so as to be stored from the inside (near the left side) of the Glen tank 2. Then, when the stored grain reaches the level of the initial capacity A1, the grain detection sensors 69 and 68 are simultaneously turned on to operate the adjustment driving unit 65, and the guide plate 62 is moved to the outside so that the midway accommodation posture B is reached. Can be switched to.

  In the midway accommodation posture B of the guide plate 62, the grains discharged from the discharge unit 60 come into contact with the guide plate 62 in a rotationally inclined state and are guided to be regulated, and sequentially on the stored grains of the initial accommodation amount A1 level. Supplied. Next, when the grain reaches the level of the halfway accommodation amount B1, the grain detection sensor 67 is turned ON, and based on this, the adjustment drive unit 65 switches the guide plate 62 to the full accommodation posture C, and the grain is reduced to the level of the full accommodation amount C1. Can be accommodated.

  The full state of the grain is notified by a notifying means such as a buzzer by detection of a full accommodation detection sensor (not shown), and based on this, the operator can stop the machine body and perform the grain discharging operation. Thus, when the grain detection sensor 69 detects that the Glen tank 2 is emptied, the guide plate 62 automatically returns from the full storage position C to the initial storage position A, and is again switched to the grain storage standby state.

As described above, the grain tank 2 that stores the grain is a grain that is discharged from the discharge unit 60 when the guide plate 62 is in the initial storage posture A in the initial stage of the combine operation when the grain tank 2 is empty. Is restricted by the guide plate 62 and is limitedly stored on the left side wall 52 and the left bottom wall 55 side, so that the position of the center of gravity of the combine as a whole is moved to a low position near the center of the machine body.
Therefore, when harvesting heavy grains that are wet with morning dew or rain water, the grains can be stored in an appropriate weight range with a low center of gravity and a good balance between left and right. It is possible to prevent the unbalance due to and to ensure stable running conditions in the field.

  Furthermore, the combine 1 provided with the Glen tank 2 configured to move the guide plate 62 in the direction away from the discharge unit 60 side according to the amount of grains accommodated when performing a combine operation in a wet field where the machine body is likely to sink. In the initial harvesting period, a heavy grain can be reliably stored from the left side without being biased to the right side of the Glen tank 2 and housed. Accordingly, it is possible to avoid significant squat travel on the crawler travel device 1a side on the right side of the airframe where the control unit 7 is installed, and to prevent right tilt travel and make it easier for the operator to perform control.

  And since the guide plate 62 can be moved from the midway accommodation posture B in the direction away from the discharge part 60 to the full accommodation posture C according to the amount of stored grains, the grain reaches the initial accommodation amount A1. And the full storage capacity C1 from the midway storage capacity B1 to the full storage capacity C1 without any rapid change of the center of gravity position, preventing the aircraft from abruptly tilting to the right and suppressing the grain discharge operation during the combine operation. Grains can be efficiently and sufficiently stored up to the full capacity C1.
