1, a supply gutter 14 with a feed helix 13 and a finishing rice gutter 16 with a finishing rice helix 15 are installed horizontally.

In arranging the supply gutter 14 and the finished rice gutter 16 inside the rotary sorting tube 11, the feed gutter 14 is placed on the scooping side of the rotary sorting tube 11 rotating from the bottom to the top as shown in FIG. The rice gutter 16 is disposed on the rotating side of the rotary sorting cylinder 11 from the top to the bottom, and the mixed rice scooped up by the pot hole of the rotary sorting cylinder 11 falls into the supply gutter 14 and is transferred to the feed gutter by the supply helix 13. The supply gutter 14 also serves as a mixed rice receiving gutter.

The discharge side of the finishing rice gutter 16 is connected to the finishing rice flow lower cylinder 17, and the brown rice flows into the finishing rice flowing lower cylinder 17. Finished rice flow lower plate 18
While the finished rice falls to the receiving gutter 19, the air pressure fan 23
The brown rice that has been sorted by the sorting wind from the rice cracker and dropped into the finished rice receiving trough 19 is taken out of the machine by the finished rice lifting machine 20.

At the discharge side end of the rotary sorting cylinder 11, there is a paddy lifting cylinder 21.
are installed in series, and the unhulled rice after sorting that is pumped up by this paddy pumping cylinder 21 is returned to the hulling section 1 with a paddy return value of 22.

Next, the small rice sorting device provided in the finishing rice gutter 16 will be explained. The bottom portion of the finishing rice gutter 16 is composed of a small rice sorting plate-like body 24. This rice sorting plate-like body 24 is
It is constructed by drilling a large number of long holes in the iron plate along the transport direction through which small rice, immature rice, bran, etc. can leak. A finishing rice helix 15 for transporting brown rice is horizontally mounted on the bottom of the finished rice gutter 16, and a small rice receiving gutter 25 is arranged below the bottom of the finished rice gutter 16, At @25, a small rice conveying helix 26 for conveying small rice is supported.

Therefore, while the brown rice pumped up by the rotation of the rotary sorting cylinder 11 is conveyed through the bottom part of the finishing rice gutter 16 by the finishing rice helix 15, the small rice in the brown rice, Immature rice, bran, etc. fall into the small rice receiving trough 25 below, and small rice, etc. in the brown rice is sorted out and removed.

It should be noted that this small rice sorting plate-like body 24 only needs to have the function of separating small rice and the like from brown rice, and may be a net, for example, and is not limited to this embodiment.

In addition, a device similar to the small rice sorting device configured in the finishing rice gutter 16 is installed in the dropped rice receiving gutter 7. Finishing rice gutter receiving gutter 19
Supply fl in the two-rotation sorting tube 11! 14 may be provided.

Next, the operation of the embodiment will be explained. Paddy is supplied to the paddy tank 2 of the hulling section 1, and each rotating part of the hulling machine is driven. Then, the paddy supplied from the paddy tank 2 to the phusher section 1 is subjected to the dehulling action, the scraped rice is sorted in the lower scraped rice wind sorting path 4, and the rice husks are discharged from the dust exhaust pipe 6 to the outside of the machine.
