(B) Prior Art As a thresher having the processing device similar to the one for collecting the sticky particles discharged together with the straw in the above-mentioned thresher, a conventional one is disclosed in, for example, Japanese Patent Laid-Open No. 60-1
As disclosed in Japanese Patent Publication No. 49317, the technical configuration described in this publication is mainly intended to collect grains scattered or discharged from the culm side. .

(C) Problems to be Solved by the Invention As described above, in the conventional structure, the main purpose is to collect the grains scattered or discharged from the culm side. It goes without saying that we will try to eliminate the loss by collecting the particles that are discharged together.
When a large amount of culm is continuously supplied to the handling room and the threshing in the handling room becomes large, it is possible to deal with this and especially devise it as a threshing machine that can be processed with a small one. It was done.

(D) Means for Solving the Problems In order to provide the threshing machine as described above, the present invention selects the handling room for accommodating the handling barrel and the handling goods from the handling room. The sorting section is set up and down, and a dust collection chamber equipped with a suction dust collection fan is provided behind these handling chambers and the sorting section to form an integrated composition.
The culm side of the handling chamber and the dust collection chamber are connected by a dust outlet, and the grain transfer device sandwiched laterally along the front side of the handling chamber causes the grain culms to be sandwiched and fed from the supply side to the culm side for threshing. In the threshing machine for processing, a cutting grain collection chamber containing a diffusion drum is provided in communication with the culm side of the handling chamber, and a dust sending control valve is provided in a connecting portion between the handling chamber and the cutting grain collection chamber. The dust control valve and the dust control valve attached to the dust outlet are interlocked with each other to change and adjust the feed amount to the stuck particle recovery chamber and the dust amount to the dust chamber. .

(E) Action Because of this configuration, the grain culm laterally fed in the handling chamber from the supply side to the culm side by the sandwiching transfer device is threshed by the rotation of the handling barrel, and the handling and unloading from the handling chamber is performed. The items are wind-sorted in the sorting section, the No. 1 item is taken out of the machine, the No. 2 item is returned to the handling room and the like and processed again, and the dust is sucked and discharged to the outside by the suction / dust fan.

Also, the one discharged from the dust outlet on the culm side to the dust chamber side is also wind-selected, and the grain becomes mainly the second grain, which is returned to the handling chamber as described above, and the dust is sucked. It is discharged outside the machine with a dust-exhaust fan.

Then, the grains and dust that do not leak from the handling chamber and are not discharged from the dust outlet are sent from the culm side to the stab grain collection chamber, where the grains are separated from the dust by the rotation of the diffusion cylinder and collected. The dust is then discharged outside the machine.

In this case, when the amount of grain culm supplied to the handling chamber becomes large, the amount of dust discharged from the dust outlet is increased by the dust control valve. Then, in conjunction with the adjustment of the dust control valve, the dust control valve provided at the connecting portion of the handling chamber and the stuck particle collecting chamber is adjusted, and the diffusion process is performed while increasing the amount of feeding to the stuck particle collecting chamber. .
