Description

Description: TECHNICAL FIELD [0001] The present invention relates to a threshing apparatus mounted on a combine.

(Prior art)

Conventionally, since the culm conveyor that conveys the threshing culm is fixed to the threshing device, when a conveyance jam occurs,
It took time and effort to remove the culm from the culm conveyor. For this reason, there has been a problem that the working efficiency is reduced.

Therefore, for example, as disclosed in the microfilm of Japanese Utility Model Application Laid-Open No. 59-172525, a grain culm that provides a clamping rod on the upper side and a feed chain on the lower side to clamp and transport the culm from the root of the grain culm. The conveying means is provided along the handle provided on one side of the threshing chamber on which the handling cylinder is mounted, and the threshed culms, which have been threshed while being transferred to the outside of the threshing chamber by the cereal culm conveying means, are disposed rearward. The culm conveyor is provided with a clamping rod and a culm conveyor arranged vertically above and below, and the culm conveyor is mounted on the lower side of the cover that covers the culm conveyance means beyond the threshing room. The cover is mounted on the upper side of the threshing apparatus, and the cover is provided so as to be movable up and down around the side opposite to the feed chain. By moving the cover upward, the clamping rod and the feed chain substantially maintain the relative posture. While separating vertically,
A threshing device has been attempted in which the holding rod and the culm conveyor are vertically separated from each other while substantially maintaining the relative posture.

Further, as disclosed in the microfilm of Japanese Utility Model Application Laid-Open No. 58-143540, a feed chain is provided on the upper side, and a clamping rod is provided on the lower side to hold and transport the culm from the root of the cereal culm. Is provided along the handle provided on one side of the threshing room on which the handling drum is mounted, and the threshed waste culm is transferred to the rear outside of the threshing room by the grain culm transporting means and is rearwarded. The culm conveyor is provided with the culm conveyor to be transported and the holding rod arranged vertically, and the culm conveyor is mounted under the cover covering the culm conveyance means in a state in which the culm conveyor is driven and inputted from the rear side. The cover is movably supported in the upper frame portion of the threshing device, and the cover is provided so as to be vertically movable about the side opposite to the feed chain. So that they are separated from each other in the vertical direction while almost maintaining the relative posture. Threshing apparatus has been tried that.

[Problems to be solved by the invention]

However, in the technique disclosed in the above-mentioned microfilm of Japanese Utility Model Application Laid-Open No. 59-172525, when the cover is moved upward, the holding rod integrally moves upward, but faces the holding rod. The culm conveyor is left on the threshing machine side.

Therefore, even if the cover is moved upward, it is difficult to sufficiently expose the culm conveyor, and there is a disadvantage that the culm conveyor cannot be sufficiently maintained.

Further, in the technology disclosed in the microfilm of Japanese Utility Model Application Laid-Open No. 58-143540, the cover equipped with the culm conveyor only covers the upper side of the culm conveyor, and the upper part of the threshing room on the front side. The cover is not covered with a pinching rod or feed chain.

For this reason, it is not possible to separate the clamping rod and the feed chain in the vertical direction only by moving the cover upward, and the efficiency of maintenance work is low.

In addition, in the technology disclosed in the microfilm of Japanese Utility Model Application Laid-Open No. 58-143540, since the culm conveyor is driven and input from the rear side, this driving is performed from the handle cylinder shaft mounted on the threshing room. In this case, there is a disadvantage that the transmission mechanism becomes complicated, for example, a transmission shaft extending long backward is required, and it cannot be provided to consumers at low cost.

[Means for solving the problem]

The present invention employs the following technical means in order to solve the above-described problems.

That is, a clamping rod 5a is provided on the upper side, and a feed chain 5 is provided on the lower side, and a cereal culm conveying means for clamping and conveying from the root of the cereal culm is provided on one side of a threshing chamber in which the handling cylinder 1 is mounted. Handle 13 provided in
A culm conveyor 2 and a clamping rod 22 arranged vertically above and below the threshing chamber, for transferring the threshed culms to the rear while being conveyed to the rear outside of the threshing chamber by the culm conveying means. Cover 3 that covers the culm conveying means beyond the threshing room
The culm conveyor 2 is mounted on the lower side of the threshing device 6 while the culm conveyor 2 is driven and input from the front side thereof, and the cover 3 is mounted on the upper side of the threshing device 6. The cover 3 is moved upward and downward, and the upward movement of the cover 3 causes the clamping rod 5a and the feed chain 5 to be separated from each other in the vertical direction while substantially maintaining the relative posture. The threshing device is characterized in that it is configured to be separated in the vertical direction so that the holding rod 22 and the holding rod 22 have a relative posture opened outward.

With this configuration, the cereal culm supplied to the cereal culm transport means is:
The sheet is conveyed rearward by being pinched by the pinching rod 5a located on the upper side and the feed chain 5 on the lower side. Then, while the tip portion passes through the threshing chamber, threshing is performed by the rotating handling drum 1.

Then, the thresh-treated waste culm is taken over by a waste culm conveying means comprising an upper culm conveyor 2 located on the upper side and a holding rod 22 located on the lower side, and is conveyed rearward.

During such an operation, when the condition is bad, such as when the grain culm to be treated is wet, clogging may occur in the culm conveying means.

In such a case, when the cover 3 is moved upward, the culm conveyor 2 also moves upward, and the culm conveyor 2 and the holding rod are moved.
22 are spaced apart in the vertical direction so that they have a relative posture that opens outward. As a result, the culm conveyor 2 and the holding rod 22
Then, the culms clogged in between can be easily removed from the outside.

In addition, since the culm conveyor 2 and the holding rod 22 are separated in the vertical direction so as to have a relative posture opened outward,
The starting end side of the culm transporting means is opened to a greater extent than the terminal end side, so that the maintenance of the starting end side of the culm transporting means which is likely to be clogged can be performed more easily.

In addition, by moving the culm conveyor 2 upward, the culm conveyor 2 is exposed, and the culm conveyor 2 itself can be easily maintained.

In addition, since the culm conveyor 2 is configured to be driven and input from the front side, for example, when this drive is taken from a handling cylinder shaft mounted in a threshing room, the transmission path is short, and this transmission mechanism is used. It can be simply configured.

Moreover, by moving the cover 3 upward, the clamping rod 5a and the feed chain 5 are vertically separated from each other while substantially maintaining the relative posture, so that a wide gap can be formed in the front-rear direction. Or the maintenance of the threshing room can be easily performed.

〔The invention's effect〕

As described above, according to the present invention, the culm transport means for providing the clamping rod 5a on the upper side and the feed chain 5 on the lower side to clamp and transport the culm from the root of the cereal stem is provided with the handle cylinder 1 mounted on the shaft. A culm conveyor 2 that is provided along a handle 13 provided on one side of the threshing chamber and that transfers the threshed culm to the rear while being transferred by the culm conveying means to the rear outside of the threshing chamber. The culm conveyor 2 is arranged vertically with the holding rod 22. The culm conveyor 2 is mounted below the cover 3 that covers the culm conveyance means beyond the threshing chamber while being driven and input from the front. The holding rod 22 is supported and mounted on the frame on the upper side of the threshing device 6, and the cover 3 is provided so as to be vertically movable about the side opposite to the feed chain 5. Pinching rod
The feed chain 5a and the feed chain 5 are separated from each other in the vertical direction while substantially maintaining the relative posture.
The threshing device is characterized in that the threshing device is configured to be separated in the up-down direction so as to have a relative posture that opens toward the outside, so that by moving the cover 3 upward,
The culm conveyor 2 and the holding rod 22 are vertically separated from each other so as to have a relative posture that is opened outward, and the start end side of the culm conveying means is opened to a greater extent than the end side, so that the clogging is likely to occur. Maintenance of the starting end side of the culm conveying means can be performed more easily. Moreover, at this time, the culm conveyor 2
Is exposed by moving upward together with the cover 3,
The maintenance of the culm conveyor 2 itself can be easily performed. In addition, since the culm conveyor 2 is configured to be driven and input from the front side, for example, when this drive is taken from the handling cylinder shaft mounted in the threshing room, the transmission path is short, and this transmission mechanism is used. The threshing apparatus can be provided simply and inexpensively to consumers. In addition, pinching rod 5a
Since the feed chain 5 and the feed chain 5 are separated from each other in the vertical direction while substantially maintaining the relative posture, a wide gap can be formed in the front-rear direction, and the maintenance of the sandwiched portion or the maintenance in the threshing chamber can be easily performed.

[Embodiment of the invention]

Hereinafter, in the example of the figure, a threshing device mounted on a combine is described as an example.

The handle cylinder shaft 10 is rotatably supported along the axis of the handle cylinder, and a receiving net 11 is provided on the outer periphery of the handle cylinder rotation. An outlet 12 is provided with an opening, and an upper cover 3 (cover 3) is provided above to constitute a threshing room. A feed chain 5 is provided along the handle 13 on one side of the threshing room so as to be inclined upward and backward in the front-rear direction a. A chain rail 5a (clamping rod 5a) is provided in a meshing manner.

The upper cover 3 is configured integrally with the upper part of the threshing chamber so as to cover the upper part of the culm chamber 14 adjacent to the rear of the threshing chamber. The center axis 15 of the vertical rotation is located on the opposite side of the feed chain 5 with respect to the
It is located on a bracket 16 provided so as to protrude below the upper surface 3a, and is mounted on the front wall 7 and the rear wall 8 of the threshing chamber. Reference numeral 41 denotes a support that urges the upper cover 3 upward.

The culm conveyor 2 is a chain conveyor in which a chain 17 is wound between a driving sprocket 19 and a driven sprocket 20 provided at the front and rear ends of a frame 18, and is not parallel to the handling cylinder shaft 10, The mounting arm 2 is skewed so as to be shifted and transported toward the tip side, and provided on the front and rear portions of the frame 18.
1 and 21, it is attached to the lower surface of the upper cover 3 in a suspended manner. At the lower end of the chain 17, a rod-shaped chain rail for holding the culm to be transferred between the chain 17 and the chain
22 (holding rod 22) is supported and mounted on the frame of the threshing device 6.

Also, a bevel gear having a shaft 23 of the driving sprocket 19 and a shaft 25 of a passive pulley 24 receiving power in parallel with the handle shaft 10 and having a bevel gear mechanism for transmitting between the shafts 25 and 23 is provided. A case 26 is provided on the frame 18. A cross flow fan 27 for discharging the sorted dust to the rear of the threshing device 6 is provided below the culm chain.

The belt transmission mechanism 4 is provided in the form of a handle cylinder pulley 27 provided at the rear end of the handle cylinder shaft 10, a fixed idler pulley 28 fixed on the outer surface of the rear wall 8 of the threshing chamber, and a tension pulley. It is constituted by one V-belt 30 wound around the tension idler pulley 29 and the passive pulley 24 of the culm conveyor 2 at an acute angle.

The essential point of the structure of the belt transmission mechanism 4 is that at least one of the two idler pulleys 28 and 29 is disposed at a position outwardly of the rotation center axis 15 of the upper cover 3 with respect to the position of the handle cylinder shaft 10. And the other idler pulley 28 is provided in the vicinity of the handle cylinder shaft 10, so that the upper cover 3 has a length that is wrapped around the four pulleys 27, 28, 29, and 24.
The relationship between the winding length L when the cover 3 is closed and the winding length 1 when the cover 3 is opened upward is L> 1, that is, if the V belt 30 has a fixed length, the relationship above the upper cover 3 It is provided so that it is appropriately loosened when it is opened.

As shown in FIG. 3, the transmission configuration from the prime mover 31 to the culm conveyor 2 is perpendicular to the prime mover shaft 32 of the prime mover 31 via a bevel gear transmission mechanism 33 provided at the front end of the handle cylinder shaft 10. A belt transmission mechanism 35 is provided between the other end of the provided transmission shaft 34, and the driving shaft 32, the belt transmission mechanism 3
5, the transmission is performed in the order of the transmission shaft 34, the handle cylinder shaft 10, and the belt transmission mechanism 4, and further transmitted in the order of the shaft 25 and the shaft 23 of the bevel gear case 26, and the driving sprocket 19 is driven and rotated. .

In addition, below the threshing room and the culm room 14 of the threshing apparatus 6 in FIG. 2, a cross flow fan 36 for discharging the sorted dust backward, a swinging sorting shelf 37, a sorting fan 38, and a foremost opening 39 are provided. , A sorting device having a second port 40 and the like.

Next, the operation of the belt transmission mechanism 4 in the transmission of the culm conveyor 2 will be described.

In FIG. 4, the upper cover 3 is pivoted upward to
Since the passive pulley 24 of the culm conveyor 2 also rotates upward about the rotation center axis 15 of the upper cover 3, even if the culm is clogged between the culm conveyor 2 and the chain rail, it is easy. The culm can be removed. At this time
The distance between 10 and the axis of the fixed idler pulley 28 does not change.
Further, assuming that the tension idler pulley 29 is fixed in position, the distance from the handle cylinder shaft 10 does not change. What changes is the fixed idler pulley 28 shaft and the passive pulley that has turned upward.
24 and the distance between the shaft 25 and the tension idler pulley
At the distance between the shaft 29 and the shaft 25 of the passive pulley 24, the fixed idler pulley 28 is slightly lower than the center shaft 15 of the upper cover 3 and closer to the handle shaft 10, so that The distance becomes far. Further, the distance between the axis of the tension idler pulley 29 and the axis 25 of the passive pulley 24 when the position is assumed to be fixed becomes short.

By offsetting this far distance and the near distance,
As a result, the overall length of the wrapping becomes L> 1, and
Since the position of the tension idler pulley 29 is provided at a position far from the barrel shaft 10 so that the amount of -1 is enough to loosen the tension of the tension idler pulley 29, the tension idler pulley 29 disengages the so-called tension clutch. "
In the same manner as in the case of the state, the transmission to the culm conveyor 2 can be set to the "cut" state.

Even if the tension idler pulley 29 is provided in a fixed position, the same transmission “cut” state can be obtained. However, if the tension idler pulley 29 is used, there is an effect that the transmission V-belt 30 can cope with elongation caused by the use time. .

 Next, the operation of the threshing device 6 will be briefly described.

The threshing device 6 mounted on the combine feeds the culm cut and conveyed by a cutting device (not shown) at the front portion thereof to the front end of the feed chain 5, and clamps and transports the feed between the feed chain 5 and the chain rail 5a. Threshing room handling cylinder 1
Is dropped by the tooth handling 9.

The threshed culm is passed from the feed chain 5 to the culm conveyor 2 provided behind the feed chain. The culm is clamped between the chain 17 and the chain rail 22 which are transmitted by the belt transmission mechanism 4 from the handle cylinder shaft 10 to the driving sprocket 19 just before the culm transfer, and the culm is transported rearward. Discharge backward.

Threshing material leaking from the receiving net 11 of the threshing room or discharged from the culm exit 12 is sorted on a swing sorting shelf 37, and straw chips, culm pieces, etc. are rearward from the rear end of the swing sorting shelf 37. Is discharged outside the aircraft.
In addition, the sorted material that has flowed downward from the swing sorting shelf 37 is subjected to wind force sorting by the blast of the sorting fan 38, and the fine granules are collected in the first opening 39.
The second product is stored in the second port 40, and the second product is returned to a threshing room or a processing chamber (not shown) by a second reduction device (not shown). The exhaust wind is sucked by the cross flow fan 36 through small dust and is blown backward.
