Description

[Detailed description of the invention] The present invention is configured such that a clamping conveyance device installed in a conveyance path for conveying cut husks in an upright position to a mounted threshing device can be vertically oscillated around its conveyance starting end. Regarding the combine root depth adjusting device, which is configured to be able to change the position of transferring the shell culm to the subsequent clamping and conveying device in the direction of the culm length, thereby adjusting the handling depth, please refer to the above-mentioned in detail. By rationally improving the swinging structure of the clamping and conveying device, it is possible to transfer data from the terminal end of this conveying device to the next clamping and conveying device in a circular manner.

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

The figure shows a combine harvester in which a reaping pre-processing section 3 is connected to the front part of the main body in which a threshing device 2 is mounted on a crawler traveling device 1.

The reaping pre-processing section 3 is connected to and supported by the main body so as to be able to move up and down freely around the horizontal axis X, and is forcibly moved up and down via a required drive device (not shown). The device is connected and supported to the main body, and three lifting devices 5a, 5b, 5c are arranged side by side in the lateral direction, and the lifting devices 5a, 5b in the lateral direction and the intermediate portion are connected to each other. Scraping packers 7, γ, and one stage of scraping packers 8 are arranged in two stages, upper and lower, corresponding to the rear part, respectively, and upper and lower parts of two stages are arranged, corresponding to the rear part of the lifting device 5c on the other lateral side. A locking conveyor belt 9 and a lower scraping packer 10 are disposed, a clipper type reaping device 6 is disposed at the end position of the pulling path, and a stock clipper type reaping device 6 having a horizontal feeding action is placed above the clipper type reaping device 6. L in the original locking conveyance device 11 and plan view
The starting end side portion of the ear tip locking and conveying device 12 bent into a shape is arranged, and the stock head clamping and conveying device 1 is placed along the lower part of the terminal side portion that has a rearward feeding action of the ear tip locking and conveying device 12.
3, this conveying device 13, and the upper auxiliary stock clamping conveying device 14 are arranged in this order.

Then, while the culm pulled up by the side-side pulling device 5a is scraped backward by the scraping packer 7.7, the root end of the plant is harvested, and the root end of the plant is harvested. The culms are conveyed laterally in a two-stage upper and lower supported state with the starting end side of the tip locking and conveying device 12, and then the culm, which has been pulled up by the lifting device 5b in the intermediate portion, is pulled up by the scraping packer 8. The base end of the plant is harvested while being raked rearward, and the culm is joined to the single conveyed culm that is being conveyed horizontally, and the culm that has been pulled up by the pulling device 5c on the other side of the side is pulled up into the upper and lower two stages. The end of the plant is harvested while being scraped backward by the locking conveyance belt 9 and the scraping packer 10, and the stem is further merged with the two conveyor culms that have been merged, and the three merged vertically The conveyed culm is conveyed with the tip side continuously held by the tip side portion of the ear tip locking and conveying device 12, and the stem side is successively held and conveyed by the plant head clamping and conveying device 13 and the auxiliary stock head clamping and conveying device 14. The threshing device 2 is transported rearward in a two-stage support state, and at the end of the transport, the lateral side of the threshing device 2 is brought into a sideways posture by the action of laying down the tip side of the tip locking and conveying device 12. It is configured to deliver the stock part to a feed chain 15 installed in the feed chain 15.

The stock head clamping and conveying device 13 is arranged such that the pinching LA3a is located on the outside of the machine body, and the conveyance chain A3b is located on the inside of the body, and the stock head holding and conveying device 12 side is disposed. The button is located at a position deviated from , and is oriented in a direction intersecting the conveyance path when viewed from above, and with the horizontal horizontal axis Y tilted toward the rear of the conveyance direction on the outside of the machine as a fulcrum, The terminal end side is configured to be able to swing up and down, so that the handling depth can be adjusted by changing the conveying shell culm delivery position from the conveying terminal end to the next auxiliary plant holding and conveying device 14 in the culm length direction. Along with this adjustment of the handling depth, the angle of inclination of the clamping and conveying surface in the length direction of the shell culm is changed when viewed from the conveying direction, and when the culm is short, it faces in the vertical direction as shown in Figure 5 A. In addition, when the culm is long, the upper part is located inward of the body than the lower part as shown in the opening of Figure 5, and the tip side of the culm is not pressed against the upper auxiliary stock clamping and conveying device 14 side. The side bed is configured to ensure that the tip side is transferred to the auxiliary stock holding and conveying device 14.

In the figure, reference numeral 16 indicates a control seat provided at the front of the threshing device 2, 1γ indicates a grain bagging section provided at the lateral side of the threshing device 2, and 18 indicates the control seat provided at the front of the threshing device 2. This is a waste straw processing device installed at the rear of the vehicle.

In summary, the handling depth adjustment device for a combine harvester according to the present invention locates the pinning rail 13a on the outside of the machine body in the conveying path for conveying the cut husk in an upright position to the mounted threshing device 2, and the conveying chain 13b is A clamping and conveying device 13 is disposed inside the machine, and the clamping and conveying device 13 is configured to be adjustable up and down centering on its conveying start end side.
The culm delivery position to the next clamping and conveying device 14 is configured to be changeable in the culm length direction, and the starting end side swing axis Y of the clamping and conveying device 13 is arranged so as to intersect with the path in plan view. In addition, the outer side of the body is inclined toward the rear side in the transport direction.

That is, by vertically swinging the clamping and transporting device 13 around the starting end side swinging axis Y, the angle of inclination of the transporting surface of this transporting device 13 in the culm length direction can be changed when viewed in the transporting direction. Utilizing this fact, the posture for transferring the shell culm to the next clamping and conveying device 14 can be stably maintained, and a good transfer can be carried out.

By adjusting the handling depth during thinning and conveying long culms, the terminal end side of the pinching conveyance device 13 is far away from the ear tip locking conveyance device 12,
Even if the tip side of the shell culm, which is supported near the end of the plant by the clamping and conveying device 13, becomes unstable, the shell culm can be pressed slightly against the ear tip locking and conveying device 12 side without causing the culm to wobble. It is possible to avoid the situation where the tip side or the middle part of the culm wobbles and becomes largely removed from the culm reception area of the next clamping and conveying device 14, and it is possible to configure the structure so that reliable delivery and conveyance can be carried out at the same temperature. Ta.

Moreover, according to the present invention, the above effect can be achieved by simply setting the pivot axis Y of the clamping and conveying device 13, for example, by rotating the conveying device 13 around two axes. Since it is not something that changes the direction of the conveyance surface,
There is an advantage that it can be implemented without complicating the drive structure or the structure of the swing fulcrum.
