Discharged outside, the mixed rice of brown rice and paddy falls into the sliding rice receiving trough 7 below, and the mixed rice that has fallen into the sliding rice receiving trough 7 is supplied to the mixed rice lifting machine 8 which also serves as a mixed rice receiving trough. Gutter 1
It is configured to be conveyed to the starting end of No. 4.

Reference numeral 10 denotes a sorting case, and inside the sorting case 10, there is a supply side end (right side in FIG. )
and the discharge side end (left side in Figure 2) is connected to the drive roller 12.
．． 12, it is rotatably supported. This rotary sorting tube 11
Inside, a supply gutter 14 with a feed helix 13 and a finishing rice gutter 16 with a finishing rice helix 15 are installed horizontally.

This supply gutter 14 and the finishing rice gutter]-6 are connected to the rotating sorting tube 11.
As shown in FIG. The mixed rice scooped up by the pot hole of the rotary sorting cylinder 11 falls into the supply gutter ]-4, and is transferred to the terminal side of the supply gutter 14 by the supply helix 13. The supply gutter 14 also functions as a mixed rice receiving gutter. The discharge side of the finishing rice gutter 16 is connected to the finishing rice receiving gutter 19 via the finishing rice flow lower pipe 17 and the finishing rice grain plate 18.
While the finished rice falls from the finishing rice flow lower cylinder 17 and the finishing rice flow grain board 18 to the finishing rice receiving trough 19, the brown rice that flows into the finishing rice receiving trough 19 and is wind-selected is the finished rice. The grains are taken out of the machine via the grain lifting machine 20.

A pumping cylinder 21 is connected to the discharge side end of the rotary sorting cylinder 11. 22 is a returning paddy return side, and the returning paddy returning side 22 extends to a position below the pumping of the pumping cylinder 21 on the rotary sorting cylinder 11 side, and is handled upward by the pumping cylinder 21. It has a function of returning the removed paddy to the shredding section 1.

Reference numeral 24 denotes an arc-shaped foreign object that is arranged opposite to the pumping-side inner circumferential surface of the pumping cylinder 21 that rotates from the bottom to the top, with a certain space in which foreign objects such as pebbles can be inserted. The upper end of this foreign matter guide surface 24 is connected to the return rice return side 22 at the guide surface. In addition, this foreign matter guide surface 24 is configured to be able to freely move near and far from the pumping cylinder 21.
