  According to the first aspect of the present invention, it is possible to enhance the threshing effect by striking and squeezing action by the tooth handling (13), and to enhance the smashing and spreading effect also by the support frame (12), thereby improving the threshing performance. Can be planned.

  In addition, since the processed material that has entered the inner space of the handling cylinder (3) surrounded by the plurality of support frames (12) is actively transferred to the rear end of the handling cylinder (3), dust removal processing can be easily performed. The threshing load can be reduced.

  According to the invention described in claim 2, in addition to the effect of the invention described in claim 1 above, the processed material reaching the conveyance end is sent to the outer peripheral side of the handling cylinder (3) by the taper portion (16). The processing effect can be enhanced.

  According to invention of Claim 3, in addition to the effect of the said invention of Claim 1 or Claim 2, since the processed material of a conveyance termination can be jumped out of a handling cylinder (3) with a jumping board. , Dust removal processing of sawdust can be performed easily.

  According to the invention described in claim 4, while the effect of the invention described in claim 3 is achieved, the processed product jumped to the outside of the handling cylinder (3) by the jump plate (17) Since it is received on the dust disposal shelf (25) and sieved, the sorting performance can be improved without hindering sorting on the lower chaff sheave.

  According to the fifth aspect of the present invention, the support frame (12) is shaped like a plate having a cross-sectional shape while exhibiting the effects of the first aspect of the present invention. Since it is formed, the striking effect on the cereals is great, the strength is robust, and the rigidity and strength of the entire handling cylinder can be sufficiently secured.
