Both the grains move to the front side, and the grains that have accumulated on the treatment basket 37 are braked on the grains with branch branches and the threshing process is sufficiently performed. Further, since the threshing product is reduced and re-sorted from the dust outlet 38 on the front side of the pretreatment chamber 8a to the front side portion of the swing sorting shelf 17, the recovery of the grain is ensured and the third scattering of the grain is reduced. be able to.

  Next, another embodiment of the threshing configuration of the handling chamber 2 will be described with reference to FIGS. 18 and 19.

  The front and rear side plates 39, 39 around which the handling cylinder 3 of the handling chamber 2 is pivoted are connected and strengthened by a frame 41, and a threshing guide plate 42 is attached to the frame 41. ,... Are formed in a comb shape.

  When the teeth 3a,... Of the barrel 3 are rotated while being inserted into the concave grooves 42a,... Of the threshing guide plate 42, the cereals adhere to the cereal when passing through the concave grooves 42a,. The grain is scraped off and separated from the cereal, and the stabbed grain of the cereal can be reduced. Moreover, by attaching the threshing guide plate 42 to the rigid frame 41, the threshing guide plate 42 is prevented from being deformed, and the effect can be maintained for a long time.

  In addition, when attaching the threshing guide plate 42 to the frame 41, as shown in FIGS. 20 and 21, the threshing guide plate 42 is attached between a bolt and a nut by interposing a cushioning material 43 such as a spring. You may make it attach to the outer side so that retraction is possible. When the threshing is overloaded, the threshing guide plate 42 is retracted and the clogging of the handling cylinder 3 can be eliminated.

  Moreover, you may comprise the threshing guide board 42 as shown in FIG. That is, the concave grooves 42a, ... of the threshing guide plate 42 may be disposed so as to be displaced toward the front side in the rotational direction, for example, corresponding to the rear teeth 3a, .... By constructing in this way, the threshing load from the front and rear concave grooves 42a,... Is scraped while being sequentially shifted, so that the threshing load can be equalized and the stabbed grains of the cereal can be scraped off. .
