由し機外へ排出される。The threshed material threshed in the processing chamber (20) leaks from the crimp net (22) and is subjected to the wind-selecting action of the Karato (29) and the swing-sorting action of the swing-sorting disc (24). It is divided into sized particles, cut-off particles, and fine straw debris and dust. The sized particles are collected by the first gutter (30) and sent to the grain tank (16) by the first conveyor (31) and the lifting cylinder (31a), and the cuttings are collected by the second gutter (32). Second conveyor (33)
And, by the reduction conveyor (33a), it is returned to the front part of the rocking sorting board (24), and fine dust is discharged to the outside of the machine via the suction and discharge fan (34).

る。The dust discharged from the dust outlet (23) at the rear end of the processing chamber (20) falls to the lower Straw rack (28). The dust received by the Strawac (28) is subjected to the rocking and combing action of the Strawac (28) above the rear end of the sorting air passage, and is subjected to drop sorting in the sorting air passage, and straw dust and grain are collected. Divided into grains. Straws and dust are collected by a suction and exhaust fan (3
It is discharged to the outside of the machine via 4), and the grain is in the lower second gutter (3
It is collected in 2) and returned to the front part of the rocking sorting board (24) by the second conveyor (33) and the returning conveyor (33a).

4) which is reduced to the front part, and the second reduction product, straw dust, which is released from the second reduction port (38) to the front part of the sorting board (24), is selected and sorted by the wind picker (29). Under the swinging action of the board (24), they are deposited on the surface layer of the grain layer and sent to the rear.

状態に保持される。The accumulated amount (height) of straw waste in the front part of the sorting board (24) is such that the second reducing port (38) is opened to the upper right side of the sorting board (24). The right side is more than the left side. The gap between the left side of the sorter panel (24) and the fixed plate (42), which is the narrowest gap between the sorter panel (24) and the rear end of the handling chamber (17) due to the amount of accumulated straw on the right side of the sorter panel (24) ( The sensor (48) is held in the non-detection state while it can pass through 45).

する。Now, the straw on the right side of the sorting board (24) is a gap (45) between the left side of the sorting board (24) and the fixed plate (42).
When the straw debris passes through the gap (45) between the right side of the sorting board (24) and the fixed plate (42) when the debris is allowed to pass through the sensor arm (5).
0) is pushed backward and the sensor (48) continues the work as it is, each clearance (45) between the sorting board (24) and the fixed plate (42) and the rear wall (41) of the handling room (17). (4
