Are installed vertically, and the cylinder 2
An end of a crimping net 4 stretched from the lower side of the handling cylinder 2 to the rear is connected to a lower end portion 3a of the mesh holding plate 3 extending to near the lower side of the mesh holding plate 3 through a mounting bracket 9, and A swing sorter 12 below the handling cylinder 2 is installed below the falling plate 10 inclined below and below the falling plate 11 inclined below the rear side of the handling chamber 7. It is configured in the same manner as the shape structure, but as shown in FIG.
a approaches the lower end 3a of the net retainer 3 and the width L
A large opening 5 is formed which is longer along the length of the opening 5 and has a shorter longitudinal length H 1 on the inlet side and a longer longitudinal length H 2 on the outlet side, and a crimping net 6 is stretched over the entire surface of the opening 5. At the same time, the periphery of the crimping net 6 is attached by an attachment 13. In addition, it is also possible to provide a structure in which a horizontal or vertical ridge for reinforcement is interposed in the opening 5.

The processing capacity of the threshed material threshed by the body 2 can be increased, and the threshed material leaking from the crimping net 6 of the net holding plate 3 is reduced by the falling plate 10.
The crimping net 4 and the falling plate 11 fall on the rocking sorter 12 from above.
The rocking sorting is effectively performed while being dispersed moderately over the entire surface in combination with the threshed material falling from the stalk, and the stabbing particles falling from the culm base side of the grain culm are removed from the crimp net 6 of the mesh holding plate 3. by leakage Do will be possible to prevent the taking out, the longer the longitudinal length H 2 of the outlet as in example, since挾扼site culms increases at the outlet side, the sticks grains fall and Moshita It can be performed more effectively.

のである。[Effects of the Invention] As described above, the present invention provides a net holding plate 3
The leakage area below the handling cylinder 2 can be increased by the area of the crimping net 6 stretched in the opening 5 of the above, and the processing capacity of threshed material threshed by the handling cylinder 2 can be further improved. The threshed material leaking from the crimping net 6 of the mesh holding plate 3 can be dropped to the side of the lower rocking plate, and the threshed material is entirely spread on the rocking plate. Efficient swing sorting can be performed while dispersing moderately. In addition, in the present invention, in particular, the length of the clip net 6 stretched on the net holding plate 3 is set such that the vertical length H2 on the outlet side is longer than the vertical length H1 on the handle side, and the length increases toward the outlet side. Since it is configured as much as possible, threshing action near the handling mouth can be kept strong, unretained handling can be reduced, and at the exit side, the crimping net works up to the upper side, so stabbing grains falling from the stem side of the grain culm Can be sufficiently recovered, and a highly accurate threshing operation with little loss is possible.
