When the sorting plate 70 is formed separately on the front plate 85 and the rear plate 86, the left inclined protrusion 72 and the right inclined protrusion 74 may be attached to a single stainless steel plate in opposite directions instead of being formed separately. .

FIG. 13 shows a left inclined protrusion 72 on one sorting plate 70.
This shows a state in which a right-slanted protrusion 74 and a right-slanted projection 74 are formed at the same time by press working.

In actual use, brown rice is much more common than unhulled rice, so the front plate 85 with the left inclined protrusion 72 is
The area is much larger than that of the rear plate 86 on which the right-slanted protrusion 74 is formed.

The sorting plates 70 are provided in several stages as shown in FIG.

A distribution device 87 is provided above the sorting plate 70 to reach each stage of the sorting plate 70. The hopper 36 opens horizontally in the width direction at the middle of the front and rear sides of the sorting plate 70. One end 88 of the distribution device 87 faces the lower part of the hopper 36, and the other end 89 is located in front of the sorting plate 70. The distribution device 87 is formed of a flat plate, and the left and right sides in the flow direction form walls that stand upright at right angles, one end 88 of which is slightly higher than the other end 89. The width of one end 88 is formed to be approximately the same as the width of the wind selection section 3. The distribution device 87 has the same width from beginning to end from one end 88 to the other end 89, and a weir 90 is provided in the middle.

The other end 89 has partition plates 9 equal to the number of sorting plates 70.

and a take-out gutter 97 are formed. 98 is a storage tank, 99 is its drop port, 100 is a guide pipe, 1
01 is an on-off valve, 102 is a control valve, and 103 is a control screw.

The lower end 104 of the guide pipe 100 opens above the socket 105 that reaches the top of the sorting plate 70.

106 is a return port formed at the bottom of the elevator 1;
07 is a discharge gutter leading to the supply tank 8, 108 is a filling hopper, 109 is a mature grain outlet, and 110 is a regulating plate.

Next, we will discuss the effect.

When the unhulled rice a is put into the loading hopper 108 formed at the lower part of the elevator 1, the elevator 1 is raised and it flows into the supply tank 8 through the discharge gutter 107.
Therefore, when the control valve 10 attached to the connecting pipe 9 at the lower end of the supply tank 8 is manually opened, the unhulled rice a is fed out little by little by the rotation of the feeding roll 14 and collides with the inclined plate 15, which causes the inclination of the inclined plate 15. The rice is supplied to the middle of rubber rolls 16 and 17 along the
is discharged.

This rice hulled material collides with the diffuser 19, and the diffuser 19
It jumps over the front rising edge 26 on the front side and hits the reflector plate 27, and is reflected off the reflector plate 27, causing the inclined guide plate 2
8 and 29, and falls into the wind selection chamber 33 through the space between the inclined guide plates 28 and 29. At this time, the width 20 of the hulling part 2 is formed only by the width of the rubber rolls 16 and 17, and is small, but especially when the grains are reflected on the reflection plate 27, they move in the axial direction of the rubber rolls 16 and 17. It is diffused and flows into the diffusion chambers in the diffusion tubes 24 and 25 formed on the left and right sides of the hulling section 2, and is thus diffused over the width 21 of the wind selection section 3 before being supplied to the wind selection section 3. Ru. That is, first, the inclined guide plate 2
8,29. This inclined guide plate 28,2
9 are both installed at a gentle slope, but the inclined guide plates 28 and 29 are installed inside the air selection housing 111, and an eccentric cam 43 is installed on the shaft 31.
The other end of the connecting rod 44, which has one end fixed to the eccentric cam 43, is fixed to the side wall of the wind selection housing 111 of the wind selection section 3. Therefore, when the shaft 31 rotates at high speed, the eccentric cam 43, The wind selection case 111 of the wind selection section 3 vibrates violently in the direction of the arrow via the connecting rod 44, and the rice grains are smoothly flowed even if the inclined guide plates 28 and 29 have a gentle slope.

The air sucked in from the suction port 32 is blown into the wind selection chamber 33 by the cross-flow windmill 30, so that light rice grain c.
is blown up into the suction path 34, sucked into the blower 35, and discharged.

The mixture of unhulled rice a and brown rice b that has fallen through the wind selection chamber 33 is stored in the hopper 36, but at this time, the least ripe grains are sorted and taken out from the takeout port 109.

When the storage amount of the hopper 36 reaches a certain level, the spring 4
The arm 39 moves downward against the elastic force of 0, so that the on-off valve 38 opens around the shaft 37, allowing the grain to fall horizontally and uniformly over the entire axial direction. The dropped mixed rice is supplied to the distribution device 87 side.

The distribution device 87 is formed of a flat plate, with walls standing at right angles on both sides in the flow direction, one end 88 of which is slightly higher than the other end 89.
The width of one end 88 is formed to be approximately the same as the width of the wind selection section 3, and the width is the same from beginning to end from one end 88 to the other end 89. Equal number of partition plates 91 are provided to form an outlet 92, and the outlet 92 is connected to the sorting plate 70 of each stage, and the eccentric cam 5 of the drive shaft 51 is connected to the sorting plate 70 of each stage.
2 is rotated, it is violently vibrated in the front-rear direction via the rod 53, so that it is spread throughout the width direction of the distribution device 87, and these are vibrated at one end 88.
When the flow is more in the direction of the other end 89, it jumps the weir 90 and spreads more uniformly, and is partitioned by the partition plate 91 provided at the other end 89, and each outlet 9
2 and is evenly supplied to each sorting plate 70.

When the drive shaft 51 of the sorting plate 70 rotates, the eccentric cam 52 rotates, and the mounting base 48 is reciprocated in the horizontal direction as shown by the arrow in FIG. 12 via the rod 53 attached to the eccentric cam 52. Since the angle θ formed by the swinging arm 49 supporting the mounting base 48 and the rod 53 is smaller than a right angle, when the sorting plate 70 moves forward due to quick return, it moves at a slow speed, but the rear side When moving, move quickly. Therefore, the sorting plate 70 is removed from the outlet 92.
The mixed rice of unhulled rice a and brown rice b supplied to the sorting board 7
0 reciprocates back and forth, the separated brown rice b is separated as shown in FIG.
The brown rice flows into the brown rice outflow gutter 83, flows from the brown rice outflow gutter 83 into the inflow port 93, and ascends the unloading elevator 5. Then, by switching the switching valve 95 to the temporary line position, the product can be taken out from the takeout gutter 97. On the other hand, the separated unhulled rice a is guided by the right inclined projection 74 and flows out from the unhulled rice outlet 80 to the unhulled rice outflow gutter 84, and from the unhulled rice outflow gutter 84 to the return port 106 of the elevator 1.
and joins with the supplied unhulled rice a.

When the work is completed, the separation work of the sorting plate 70 stops, and both the unhulled rice a and the brown rice b are removed from the unhulled rice outlet 8.
Since the unhulled rice flows out from 0 into the outflow gutter 84, it can be stored in the storage tank 98 via the return gutter 96 by switching the switching valve 95 to the position shown by the solid line in FIG. The stored mixed rice flows into the receiving port 105 by opening the on-off valve 101, and is supplied from the receiving port 105 to the uppermost sorting plate 70 to be sorted.
