(effect) Next, we will discuss the effect.

Referring to FIG. 2, first, we will describe the general operation. The unhulled rice supplied to the feeder elevator 1 rises and is supplied to the hulling section 9, where it becomes unhulled rice, brown rice, and rice husks. , these are the wind selection section 21 on the side.
Here, the rice husks are wind-selected, and only unhulled rice and brown rice flow into the swing-type sorting section 41 and are sorted.
The unhulled rice is returned to the supply elevator 1, and the brown rice is excluded from the system.

Specifically, when unhulled rice is supplied to the loading port 5, it is raised inside the supply elevator 1 by the bucket belt 4 and stored in the fixed hopper 8 through the supply port 7. When the stored amount exceeds, it flows out from the overflow hole 11 and is returned to the filling port 5.

By opening the on-off valve 12, the unhulled rice stored in the fixed hopper 8 is fed out by the feed roll 17, and flows over the inclined sink plate 18 to the huller, which is diagonally above and below the lower end of the hopper. roll 13,
The rice is supplied during the period 14, is hulled, and flows into the swinging type diffusion device 22. The rotating shaft 24 of the suction blower 23 is rotated, and the eccentric ring 25 is fitted to the rotating shaft 24.
When the rod 26 rotates, the eccentric wheel 25 rotates, and the rod 26 whose upper end is fixed to the eccentric wheel 25 vibrates diagonally up and down.Therefore, the swinging diffuser 22 fixed to the lower end of the rod 26 vibrates diagonally up and down. Vibrate.
During this time, the leaf spring 27 elastically supports the swinging diffuser 22.

Therefore, when the hulled rice in the swinging type diffusion device 22 flows out from the lower end opening 28,
It falls in a state where it is uniformly dispersed in the width direction and is supplied into the distribution supply gutter 29. Thus, the air blown by the blower 19 passes through the selective air passage 20 and below the rocking diffuser 22, and passes through the lower end opening 2.
When the rice husks pass through the rice grains falling from 8 and rise into the wind sorting section 21, light rice husks are blown away and sorted, and the rice husks are sucked by the suction blower 23 and removed from the system.

The hulled grains falling uniformly from the lower end opening 28 are supplied onto a distribution supply gutter 29. The distribution supply gutter 29 is integrally attached to the sorting plate 31, and the sorting plate 31 is attached so as to be swingable in the left and right direction by the swinging support 33, so the distribution supply trough 29 is also attached to the sorting plate 31. Therefore, it is fed by the feed protrusion 30 on the bottom wall and distributed and supplied to the sorting plates 31 of each stage. The unhulled rice and brown rice supplied onto the sorting plate 31 are sorted by the action of the sorting protrusion 34, and the brown rice is taken out from the brown rice outlet 35 into the brown rice channel 38, supplied to the finished rice take-out elevator 39, and raised to become finished rice. It is stored in the storage tank 40. The separated unhulled rice is supplied to the mangoku 42 from the unhulled rice take-out port 36, straw waste etc. are removed, and only unhulled rice flows into the unhulled rice return port 37, where it joins with the unhulled rice from the loading port 5 and is reprocessed. .
