It is possible to efficiently remove dust to the outside of the machine while sorting out the dust that is sent to the rear of the body, and also to sort out the dust with a chaff sieve and collect the second thing.
The present invention is to provide a system that enables dust removal treatment to be carried out reliably and satisfactorily so as to prevent dust loss from occurring, and to be carried out suitably.

流れる風に合流することになる。[Function] Therefore, during work, the processing cylinder 3 rotates as shown by arrow A, and the pressure air generated by the blowing fan 2 passes through the grain sheave 18 from above the grain flow board 26 to the chaff sheave 17. The suction air flows downward as shown by arrow B, and while a part of the air flows, suction air flows from above from the chaff sheave 17 to the stroke rack 19 to the suction dust remover 21 as shown by arrow C, and as shown by arrow B. The wind flows from the stroke rack 19 toward the processing chamber 3a as shown by arrow D, and also flows through the air passage 8 on the chaf sheave 6.
The dust flows inside as shown by the arrow H, and further flows out of the machine from the dust exhaust port 5 as shown by the arrow H, but a part of it flows from the chaff sheave 6 onto the flow grain board 20 as shown by the arrow T. As the wind flows, it turns on the second gutter 4 as shown by arrow C and merges with the flowing wind as shown by arrow b.

されてそのまま２番樋４に落入することになる。 Therefore, while the material to be sorted falling from the handling chamber 10 is being fed by the chaff sieve 17, the No. 1 material that leaks out from the grain sieve 18 and is sorted by wind and falls into the No. 1 gutter 28, and is passed through the chaf sieve. The second item falling while being sorted from the chaff sheave 17 to the stroke rack 19 is sorted by the flowing wind as shown by the arrow B, and the upper part of the dust from the chaff sheave 17 to the stroke rack 19 is sucked into the suction dust remover 21. The dust that is discharged outside the machine from the rear of the stroke rack 9 while receiving wind in the two directions of the arrows is taken into the processing chamber 3a by the processing cylinder 3 and processed. The dust that is sent to one end without being lowered is discharged outside the machine from the dust exhaust port 25, and the second dust that leaks from the concave 9 and the dust on the chaff sheave 6 are discharged in the direction of the arrow H in the air passage 8. The dust is sorted by the wind, and is discharged outside the machine from the dust exhaust port 5 by the wind in the direction of the arrow, and leaks from the chaff sheave 6.
The articles are urged to be sent downward by the wind in the direction of arrow T, and fall directly into the second gutter 4.

に実施できる特長を有する。[Effects of the invention] As described above, the present invention has a swing sorting body A extending toward the rear of the aircraft from between the upper and lower handling trunks 1 and the blowing fans 2.
At the rear upper part of the processing cylinder 3 is placed in a direction perpendicular to the processing cylinder 1.
In the threshing machine configured by installing horizontally, a chaff sheave 6 is installed at the rear of the swinging sorter A diagonally above the second gutter 4 so as to approach the dust exhaust port 5 at the rear of the machine, A concave 9 facing above the chaff sheave 6 at an interval of an air passage 8 is provided below the processing cylinder 3 whose front side communicates with the sorting dust chamber 7 formed above the swinging sorter A. Because of this structure, the untreated dust sent out from above the oscillating sorting body A can be effectively taken in and processed by the processing cylinder 3, and it is prevented from leaking from the concave 9 after being processed by the processing cylinder 3. The dust on the chaff sieve 6 can be effectively separated from the dust on the chaff sieve 6 by the wind flowing in the air passage 8, and the dust can be carried on the wind and removed. It has the advantage of being able to be collected well, and being able to perform dust removal treatment reliably and well without causing No. 3 loss, so that it can be carried out suitably.
