Is done. If the sorted kernels include crushed granules B generated by breaking the sized granules C in the middle of the major axis, the crushed granules B
Is leaked from a circular hole 3 provided in the long hole-shaped sorting hole 2 and having a diameter larger than the short diameter of the long hole portion. This circular hole 3
Since the crushed granules B are provided after the beginning of the long hole of the sorting hole 2 in the rotation direction D of the sorting cylinder 1, the crushed granules B always pass through the long hole portion of the sorting hole 2 and are aligned at the long hole portion. Is surely leaked through the circular hole 3. The sized granules C not leaked in the long hole portion of the sorting hole 2 do not leak out of the circular hole 3 because the major axis is larger than the diameter of the circular hole 3, and the sorting cylinder 1
It is transported inside. As described above, in the sorting cylinder of the present invention,
Since not only the immature grains A having a small diameter but also the crushed grains B having a diameter larger than the short diameter of the long hole of the sorting hole 2 can be leaked, the sorting can be surely performed, the clogging hardly occurs, and the sorting can be efficiently performed. it can. Further, the above-described effect can be obtained only by providing the circular hole 3 having a diameter larger than the short diameter of the long hole after the starting end of the long hole of the selection hole 2 in the rotation direction D of the sorting cylinder 1. Easy.

As shown in FIG. 2 (a), small-diameter immature grains A leak out from the long holes of the sorting holes 2. As shown in FIGS. 2 (b) and 2 (c), the grains which are not leaked at this time and have a diameter larger than the short diameter of the long hole of the sorting hole 2 are aligned in the long hole portion of the sorting hole 2 and are separated. Then, the crushed granules B which are apt to be clogged in the conventional sorting hole leak as shown in FIG. 3 (a). Since the major diameter of the sized C is larger than the diameter of the circular hole 3, it does not leak from the circular hole 3 as shown in FIG. The sized granules C remaining in the sorting cylinder 1 are then carried further upward by the spiral body 7 to be discharged from the sized granulation outlet 14, received by the partition plate 11, and then stored in the storage tank 1.
It is sent into 5. The small-diameter immature grains A and the crushed grains B leaked from the sorting hole 2 to the outside of the sorting cylinder 1 are received by the partition plate 12 and then taken out of the take-out chute 13 to the outside of the machine body.

本発明は添付図面の構造に限定されるものではない。As described above, in the sorting cylinder 1 of the present invention, the crushed granules B, which easily cause clogging, can be reliably leaked out.
The structure is simple and the operation is simple. In the embodiment of the present invention, the position of the circular hole 3 of the sorting hole 2 is set to the end in the rotation direction D of the sorting cylinder 1. However, as shown in FIG. It may be provided anywhere after that. Further, the number of the circular holes 3 is not limited to one, and a plurality of circular holes 3 may be provided in one sorting hole 2 as shown in FIG. Further, even if the circular hole 3 is an elliptical hole or the like, it is a circular hole.
If it does, the same effect will be achieved. It should be noted that , in the claims, the numbers are written for convenience with the objects of the drawings, but the present invention is not limited to the structure of the attached drawings by this entry.
