In conjunction with 5), the spreader (94) is configured to perform different rotations in the left-right rotation direction. In this case, the blade (97) has a rotating shaft (9) on the inner diameter side.
The left and right disks (96) are provided symmetrically on the left and right discs (96) so as to be offset with respect to 4a) and have a receding angle with respect to the rotation direction.

A three-dimensional triangular guide plate (10) is provided between the front sides of the right and left spreaders (94) on the upper surface of the diffusion plate (95).
3) is arranged, and the front side of the spreader (94) is arranged so as to be wrapped to the rear side of the main body by a certain size (T) in a side view, and is connected to the end of the second flow grain plate (41). After being installed, the dust guide plate (10
4) The rear end and the front side of the spreader (94) are wrapped by a predetermined dimension (H) in a side view so that the rear end of the guide plate (104) faces upward from the spreader (94), and the dust is discharged. Make sure that the dust falling from the mouth (29) is spreader (9
4) Dust from the post-sorting plate (32) is dropped on the spreader (94) while being placed on the top, so that the dust is uniformly diffused.

This embodiment is constructed as described above, and when the threshing process is performed by the handling cylinder (5), the waste cut short by the cutting blade (88) is discharged downward from the dust discharge port (29). And when the dust after the sorting process by the front and rear sorting machines (31) and (32) is discharged and dropped below the rear end of the rear sorting machine (32), directly or by the guide plate (104). ) Is surely dropped onto the spreader (94) by the guide of (1), and the spreader (94) having different rotation directions on the left and right sides uniformly spreads behind the threshing unit (4). Also, in this case, a cutting blade (88) is provided on the side of the handling drum (5) having a large rotational inertia force to cut the straw, as compared with a means for simultaneously cutting the straw with the spreader (94). However, even with the structure that enables the above, the driving force for cutting can be reduced without significantly increasing the rotational load of the spreader (94) and the handling cylinder (5).
