述のように四番口55へ落入する。 At that time, the inserted grain culm is rapidly moved to the rear by the solid teeth 40 at the starting end of the handling barrel 11, and the linear teeth 40a near the base of the conical part and the solid teeth 40b following it move the grain culm to the rear during the threshing stage. While suppressing the shedding of a large amount of grains all at once, the grains are shifted to the normal handling teeth 40c... and the grains are threshed almost evenly.
At the terminal end, linear teeth 40d are arranged in a row...
Solid teeth 40e having a lead angle lead the grain culm whose movement is suppressed by the linear teeth 40d while combing.
The waste straw is discharged from the culm discharge port 52, and while it is conveyed diagonally backward by the waste straw conveying device 53, the remaining stick particles are removed as described above. It falls into the mouth 55.

The second product from the second reduction cylinder 47 collides with the entire width of the flow plate 27a, disperses and merges, and the grains are transferred to the blower 3.
The straw waste falls into the first receiving gutter 28 from the sorting net 29 while being screened by the sorting wind in step 3, and the straw waste including the second straw remaining on the sorting net 29 moves to the second sorting net 29a and is sieved. At the same time, it is selected by the sorting air from the cross-flow fan 35.

The treated straw waste that has moved to the outlet is discharged from the outlet 42 by the treated teeth 16b that do not have a lead angle.
It is thrown towards the suction windmill 34 from the suction windmill 3
4 is air-sorted by a cyclone sorting wind constituted by a front guide plate 43 and a rear wall 19, and heavy items such as grains fall into the processing section 31 together with those transferred from above the second sorting net 29a, The second processing cylinder 31b processes the fallen objects with its second processing teeth 31c while rotating them, and sequentially transfers them to the suction windmill 34.
