(Prior art) Conventionally, an immature grain sorting perforated plate A is placed on the upper surface of a square side frame, and a receiving net B is stretched on the lower surface of the square side frame, and a dynamic chamber is formed between the perforated plate A and receiving net B, It is known that a ball C is accommodated in the dynamic chamber, and a plurality of partition plates E are arranged in parallel in the dynamic chamber to divide the dynamic chamber into several chambers.

Furthermore, in the publicly known Japanese Patent Publication No. 54-97, a sorting net is provided on the upper surface of the square side frame, a corrugated plate is provided on the lower surface of the square side frame, and a dynamic chamber is formed between the sorting net and the corrugated plate,
In the case where a ball is housed in the dynamic chamber,
A plurality of partitions made of wide band plates are placed horizontally in the dynamic chamber to divide the dynamic chamber into several rooms, and the distance between the top surface of the partition and the bottom surface of the perforated plate is such that the ball is in the adjacent chamber. describes a clogging prevention device for a grain sorting device that is spaced so that it does not move.

(Problems to be Solved by the Invention) The clogging prevention device of the former immature grain sorting device had a defect in that a portion of the ball C did not work. That is, since the radius G portion of the ball C shown in FIG. 5 does not act on the lower surface of the immature grain sorting perforated plate A, the clogged rice in this portion cannot be removed.

In the latter case, multiple wide band partitions are installed horizontally in the dynamic chamber, so the balls do not act on the top surface of the band partitions, so it is not possible to remove clogging particles from this area. . Also, for the same reason as the former,
Since the radius portion of the ball does not act on the bottom surface of the sorting screen, it is not possible to remove clogging particles from this portion.

(Means for Solving the Problem) Therefore, in the present invention, the immature grain sorting perforated plate 22 is placed on the upper surface of the square side frame 21, and the receiving net 23 is placed on the lower surface of the square side frame 21.
