A processing barrel 6 is installed in the processing barrel chamber 3 so as to communicate with the processing barrel 6, and has a large number of processing teeth 5 implanted on the outer peripheral surface perpendicular to the processing barrel axis 4. The processing cylinder 6 is rotatably mounted on a shaft so that it can rotate downwardly. 6 is higher than the treated teeth 5 and bulges upward so as to be separated upwardly, and the entire surface is formed into a curved guide surface 7.

The oscillating sorting body A equipped with the second grade is extended, and the sieve line 24 group is extended from the terminal end of the oscillating sorting body A, which is behind the chaff sieve 21, toward the lower side of the opening 2 of the processing barrel chamber 3. A pressure fan 24 and a No. 1 helical conveyor 25 are arranged below the oscillating sorting body A, and a No. 2 helical conveyor 26 is arranged below the sieve wire 23 and the receiving net 17. The net 17 is installed so that the lower side thereof communicates with the suction dust ejector 8 side.

吸引されて機外に排出されることになる。 During the threshing operation, the material to be sorted leaking from the crimp net 13 and the waste material falling from the dust inlet 14 are separated by the chaff sieve 21.
The grains leaking from the clean sieve 22 are wind sorted and fall into the No. 1 spiral conveyor 25, and the waste materials sent out from the chaff sieve 21 are shaken and sorted by the sieve wire 23, and the second grains are sorted by the lower No. 2 spiral conveyor. Dust and the like that fall into the spiral conveyor 26 and are sent out from above the sieve line 23 as shown by arrow C are transferred to the processing barrel chamber 3 by the processing teeth 7 of the processing cylinder 6 that rotates as shown by arrow D.
The grains and the like that leak through the receiving net 17 are sorted out by the suction air from the suction dust extractor 8, and are then stirred and processed in the processing barrel chamber 3.
The dust that falls onto the spiral conveyor 26 and is discharged to the rear of the processing barrel chamber 3 is directly sucked into the suction dust remover 8 and discharged outside the machine.

行なうことができることになる。 In that case, the waste that circulates inside the processing barrel chamber 3 and reaches the opening 2 side is moved from the rear wall to the front wall along the curved guide surface 7 forming the upper circumferential wall, as shown by the arrow H. The water is forced to flow toward the peripheral surface of the processing cylinder 6 on the side of the opening 2, and the flow continues to the lower side of the processing cylinder 3 as shown by the arrow B, so that the sieve line 23 is shown by the arrow C. Collision with the discharged waste material is thus prevented, and the processing teeth 5 extending into the opening 2 can take in the waste material satisfactorily.

な構造にして好適に実施できる特長を有する。 In this way, the present invention has a processing barrel chamber 3 which has an opening 2 at the front end corresponding to the terminal end side of the swing sorting body A extending rearward from the lower side of the processing chamber 1.
A processing barrel 6 having a large number of processing teeth 5 implanted on its outer peripheral surface is rotatably mounted in the processing barrel chamber 3 in an axial direction perpendicular to the processing barrel shaft 4. The upper circumferential wall forming the processing barrel chamber 3 has its front part A approach the tip of the processing tooth 5 above the opening 2, and its rear part bulges upward to form a curved guide surface 7 as a whole. At the same time, since a suction dust ejector 8 is connected in communication with the rear of the processing barrel chamber 3, the dust etc. discharged from the handling chamber 1 can be sent to the processing barrel chamber 3 by the oscillating sorter A. The dust can be removed by the suction dust ejector 8 while the processing cylinder 6 performs good processing. In particular, the upper circumferential wall forming the processing barrel chamber 3 has its front part approached the tip of the processing tooth 5 above the opening 2, and its rear part bulges upward to form a curved guide surface 7 as a whole. Therefore, the waste material circulating inside the processing barrel chamber 3 is forcibly guided along this curved guide surface 7 from the rear wall toward the peripheral surface of the processing barrel 6 in the front section. This prevents the feeding of waste from the swinging sorter A side, and allows the processing teeth 5 to actively take in the dust on the opening 2 side, preventing stagnation or clogging of the dust feeding. It is possible to improve the threshing performance by effectively sorting and treating waste without having to do so, and it has the advantage that it can be carried out suitably with a simple structure.
