A straw removal cutter is provided at a lower intermediate position with the device, and a cover for switching the straw removal flow path that is swingable up and down about a rear fulcrum is provided at the upper inlet of the straw removal cutter,
By placing the cover in the upper position, the waste straw from the threshing device is supplied to the waste straw cutter, and by placing the cover in the downward position, the waste straw from the threshing device is supplied to the waste straw binding device. The present invention relates to a combine waste straw processing device configured to supply waste straw to a combine harvester.

[Conventional technology]

When cutting waste threshing straw using the above-mentioned waste straw processing device, in order to supply the waste straw to the waste straw cutter, the cover is placed in the upper position to cut the waste straw from the threshing device to the waste straw cutter. It was decided to form a straw channel. and,
The police car was placed at the rear of the aircraft so that the cover in the upper position did not interfere with the police car, which was constantly being driven.

[Problem that the invention attempts to solve]

In this way, when cutting the threshed waste straw,
The waste straw carried out from the threshing device via the waste straw flow path was guided into the waste straw cutter, but since the waste straw is carried out from the threshing device and simply falls by itself, the waste straw flow is There was a problem that it was easy to get caught in the middle of the road and get stuck.

An object of the present invention is to provide a combine harvester waste straw processing device that can solve these problems.

[Means for solving problems]

The combine waste straw processing device according to the present invention is
In the waste straw processing apparatus having the above configuration, the cover is positioned such that the tip trajectory of the packer overlaps with the cover when the cover is in an upward position, and It is characterized by forming a notch through which the tip of the packer can pass when the cover is in the upper position.

[Effect]

When cutting waste threshing straw using a waste straw processing device having such a configuration, the cover can be placed in an upward position to allow communication from the threshing device to the waste straw cutter in order to supply the waste straw to the waste straw cutter. The cover that is positioned above the waste straw flow path is arranged so as to overlap the locus of the tip of the packer, and the tip of the packer that is positioned above the cover is placed so as to overlap the locus of the tip of the packer. Since a notch is formed through which the straw can pass, the waste straw carried out from the threshing device to the waste straw flow path is directed downward by the tip of the packer, which passes through the notch formed in the cover, which is positioned in the upper position. It will be forcibly scraped off.

[Effect of idea]

Therefore, in addition to the force that causes the waste straw to fall from the threshing device to the waste straw flow path, a forced downward scraping force acts on the waste straw, causing the waste straw flow path to be scraped off. The conventional problem that the waste straw tends to get caught and stay in the middle of the process is solved.

In addition, when performing tying of waste straw from the threshing device, by placing the cover in the lower position as in the past, a waste straw flow path leading to the waste straw tying device is formed, and a waste straw flow path leading to the waste straw tying device is formed. It goes without saying that by applying the original raking force, that is, the raking force toward the rear of the machine body, the waste straw can be smoothly supplied to the waste straw binding device.
