Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a clamping conveyance width that clamps the tip of the waste straw sent out from the threshing section in a horizontal position and conveys the waste straw to the inside of the machine, that is, to the already cut side. This invention relates to a waste straw processing device for a mobile threshing machine equipped with a shifting device.

In the conventional waste straw processing device of a mobile threshing machine, the above-mentioned clamping and conveying width shifting device is installed in an inclined position such that the end of the conveyance is closer to the tip of the waste straw in plan view, and the device is arranged in an inclined position so that the discarded straw is turned sideways. The configuration was such that the grain was transported backward while being shifted toward the ear side while maintaining the posture, but when using this method, the angle of inclination of the clamping and conveying width shifting device with respect to the direction of movement of the machine cannot be increased unnecessarily, and the threshing Since the inclination angle is limited to a range that allows the transfer of waste straw from the threshing section to be carried out without difficulty, in order to ensure a sufficient width allowance, it is necessary to increase the rearward protrusion length of the nipping conveyance width shifting device from the threshing section. It was necessary to make the aircraft extremely large, which caused problems such as the size of the captain.

In view of these points, the present invention is capable of securing a sufficient width margin while keeping the length of protrusion to the rear small, and also makes it possible to keep the direction of lodging of the discarded straw bundles discharged onto the field constant so that they can be neatly organized. The purpose is to make it possible to process it.

The waste straw processing device for a mobile threshing machine according to the present invention includes:
In the above mentioned device, at the end of the waste straw conveyance path of the pinching and conveying width shifting device, the stock base of the ear tip holding and removing straw is changed to a vertical position in which it hangs downward by its own weight, and the end of the conveyance path The lower portion of the section is placed in contact with the stock base of the vertically-positioned fallen waste straw that has come off the terminal end of the clamping and conveying width-shifting device, and the vertically-positioned waste straw is moved from the stock base side to the top side further. It is characterized by being provided with a receiving plate that is laid down in the widthwise direction.

In other words, when conveying the straw to the rear, the tip of the straw is held between the ears and the stock base of the waste straw is swung downward by its own weight, and the entire waste straw is changed to a vertical position, thereby allowing the width of the straw to be moved inward to the inside of the machine. Therefore, the clamping and conveying width shifting device may be of a length sufficient to change the removed straw from the horizontal position to the vertical position as described above. Compared to the conventional device mentioned above, which brings the width closer together in the direction,
Although it was possible to shorten the length of the machine by significantly shortening the rearward protruding length of the clamping and conveying width shifting device, the tips of the discarded straw were clamped at the end of the conveyance path of the clamping and conveying width shifting device and hung down from the plant base. It is in a vertical position, and from this state, the receiving plate is used to further lower the tip side of the straw in the vertical position, centering on the stock base, so that the top of the stock is tilted sideways. As the grains are located at the same position, sufficient width adjustment is possible, and the direction of lodging and release into the field is also constant, eliminating the drawback of the movable threshing machine inadvertently collapsing into the path of movement for the next stroke. Even if it is discharged without being bundled, it has the advantage that it can be discharged in a well-organized manner and post-processing is also easy.

In particular, when the conveyance path of the clamping conveyance width adjustment device is configured so that the end of the conveyance is positioned higher in side view, the discharge straw may be improperly grounded, regardless of the length of the straw or short culm. It is possible to reliably change the posture to the above-mentioned vertical position without any problems, and to make the width adjustment constant. In addition, when the conveyance path of the clamping conveyance and width adjustment device is installed in an inclined position in which the end of the conveyance is disposed on its side in a plan view, the width is also reduced by this inclined conveyance. Since the width can be moved closer to each other, it is possible to greatly increase the overall width shift margin.

Hereinafter, an embodiment of the present invention will be described based on the drawings. The waste straw sent out from the threshing section 1 in a sideways posture is held and conveyed rearward by the driving conveyance chain 2 at the upper part and the holding rail 3 at the lower part. A device 4 for bringing the width closer to the inside of the horizontal body, that is, to the tip side of the side-turned waste straw, is provided in such a state that its conveyance path 5 is located in an inclined position such that the conveyance end side is located inside the machine body in plan view, and ,,the transport path 5
