(In the case of grains that are hardly damaged by rice and wheat) Since the present invention is configured as described above, the communication port 36 of the air selection chamber of the processing chamber 30 is closed by the switching body 37 and only the communication port 35 of the handling chamber is opened. When the body is advanced with the handling cylinder 13 being rotated at a rotation speed corresponding to the rice and wheat, weeding is performed between the bones of the field by the weeding body 5, and the weeded culm is scraped by the scraping reel 6. The stalks stalked rearward are cut by the cutting blade 7, and the stalks cut by the stalks are sent further rearward by the scraping reel 6 and collected by the auger 9. It is supplied to the chamber 10.

The cereal stalks introduced into the handling room 10 are conveyed rearward by the spiral teeth 14 of the rotating handling drum 13, and the grains degranulated from the stalks leak from the handling net 18 and enter the wind selection chamber 19. The first product enters the conveyor 24 and is taken out of the machine, and the second product enters the second conveyor 25.

[0015] The second product entering the second conveyor 25 is the sixth product.
As shown by a dotted arrow in the drawing, the second return device 33 causes the processing chamber 3
0 is supplied to the starting end of the grain, and is transported to the terminating side by the processing cylinder 31.

, And is returned to the handling room 10 from the handling room communication port 35, and the threshing process is performed again. Therefore, even for rice and wheat that is difficult to shed from the cereal stem, the processing step is as follows: handling room 10 → wind selection room 19 → second conveyor 25 → second return device 33 → processing room 30 → handling room 1
Since it becomes 0, it becomes longer and can be completely processed and efficient threshing work can be performed. (In the case of cereal that is easily damaged such as soybeans) Since the present invention has the above-described configuration, the communication port 35 of the treatment room 30 is closed by the switching body 37 to open the communication port 36 of the air selection chamber. When the body is advanced with the handling drum 13 rotated at a rotation speed corresponding to soybeans and the like, weeding is performed between the bones of the field by the weeding body 5, and the weeded grain culm is moved backward by the scraping reel 6. The stalks that have been scraped and stalked are cut by the cutting blade 7, and the stalks that have been cut are supplied to the handling room 10 of the threshing device 3 by the scraping reel 6.

The grain culm introduced into the handling room 10 is threshed by a spiral tooth 14 of a handling drum 13 which rotates similarly to rice and wheat.
Kernels leak from the handling net 18 and enter the wind selection chamber 19 where they are selected by wind. The first product enters the first conveyor 24 and is taken out of the machine, and the second product enters the second conveyor 25. Second conveyor 2
5 is supplied to the starting end of the processing chamber 30 by the second return device 33, as indicated by the dotted arrow in FIG.
When transported to the terminal side by the processing cylinder 31, since the communication port 36 for the wind selection chamber is not closed by the switching body 37, the communication port 36 is returned directly from the communication port 36 for the wind selection chamber to the interior of the wind selection chamber 19 and is again subjected to the wind selection processing. Is done. Therefore, even if the soybean is easily scratched, it does not pass through the treatment room 10 from the treatment room 30 but directly into the air selection room 1.
Since it is returned to 9, the processing step is prevented from being shortened and the epidermis is prevented from being damaged, and soybean having high commercial value can be obtained.
