(effect) Next, we will discuss the effect.

When the unhulled rice is put into the staking hopper 6, the staking port 5
The grain enters the elevator 1, is lifted by the elevator 1, and stored in the storage tank 7. When the on-off valve 13 is opened by an appropriate amount, it flows into the hulling section 8 through the drop port 12, and is fed out little by little by the feed roll 14. Guide board 1
5. Flows over the rubber piece 16, and the hulling rolls 17, 18
The mixed rice that has been hulled flows into the diffuser 19, and when it is discharged from the outlet 31 of the diffuser 19, most of the light grains, dust, rice grains, etc. are removed from the sorting air path. The air is sucked into the wind body 21 by the suction air flowing through the air filter 24 and discharged to the outside of the machine by the suction fan 22 .

However, the mixed rice with a heavy specific gravity and the remaining paddy grain...
Dust, rice cake, etc. are supplied from the discharge port 31 of the diffuser 19 to the supply gutter 30, but since a scraping plate 33 is provided exactly at the position where the mixed rice, etc. falls, they are not leveled immediately and are left there. and is stirred so as to be scooped up at the lower end of the scraping plate 33,
At that time, they are chosen by the wind. That is, the supply gutter 30 swings violently in the front-back direction together with the swing-type sorting device 27, whereas the lower end of the scraping plate 33 is fixed so as not to move, and the feed gutter 30
0, the position of the raking plate 33 does not change, but since the supply gutter 30 swings back and forth, the grains on the supply gutter 30 are raked up by the raking plate 33 and piled up. It rises in shape, paddy grain,
Light items such as straw waste and rice cake float to the upper layer and are sucked and removed into the wind barrel 21 by the suction air of the sorting air passage 24. Therefore, the mixed rice from which paddy grains and the like have been completely wind-selected is sent by the protrusion 32 of the supply gutter 30 and falls into the distribution supply gutter 29, and the distribution and supply gutter 29 sends it to each sorting plate 2.
8 and is well sorted.

(Effects) As mentioned above, in the past, a diffuser was provided at the bottom of the hulling roll, a supply gutter was provided below the diffuser via a sorting air passage, and a distribution feed gutter was provided at the bottom of the feed gutter. It is publicly known. However, in the hulling device having the above structure, the selection air passage between the diffuser and the supply trough alone was not sufficient to screen the rice grains, and a considerable amount of the rice grains were supplied to the supply trough. In this case, if the mixed rice on the supply gutter is heaped up, you can expect wind selection effect every time it is shaken, but if it is leveled out, there will be almost no wind selection and the rice will be fed to the distribution feed gutter. There was a defect that caused the problem.

However, in the present invention, the mixed rice that has been hulled by the hulling rolls 17 and 18 is diffused by the diffuser 19, and the swinging supply gutter 30 is provided below the diffuser 19 to receive the falling mixed rice. In a device in which a distribution supply gutter 29 of a swing type sorting device 27 having a multistage sorting plate 28 is provided below, the supply gutter 3

When the mixed rice hulled by the rolls 17 and 18 is diffused and discharged from the diffuser 19, most of the light grains, dust, rice grains, etc. are transferred into the wind barrel 21 by the suction wind flowing through the sorting air passage 24. Although the remaining rice grains, dust, rice grains, etc. are sucked in, they may be supplied to the supply gutter 30 from the outlet 31 of the diffuser 19, but the scraping plate 33 is located exactly at the position where the mixed rice, etc. falls. Because it is set up, it is not leveled immediately, and it piles up there,
In addition, the rice is stirred so as to be scooped up at the lower end of the raking plate 33, and at that time, it is wind-selected by the wind, so that the mixed rice with completely wind-selected paddy grains, etc. is sent to the supply gutter 30.
It has the effect of being sent by the protrusion 32 and falling into the distribution supply gutter 29, and being supplied to each sorting plate 28 by the distribution supply gutter 29.
