Next, the structure of the wind sorting section 2 and the hulling section 3 provided on the upper part of the swing type grain sorting section 1 will be explained.
Reference numeral 45 denotes the frame, which is placed above the frame 9 of the swing type grain sorting section 1, and the wind sorting section 2 is provided inside the frame 45;
The rice hulling part 3 is placed on the upper part of the frame 45.

is installed. An air suction port 60 is provided above the cross-flow fan 59, and an air selection chamber 61 is formed at the blow-off portion of the cross-flow fan 59. 62 is the first grain removal section, and 63 is a waste grain removal section. Also, 64
65 is a suction blower, 65 is a suction port, and 66 is an exhaust port.

(effect) Next, we will discuss the effect.

The tensioning hopper 24 of the supply elevator 5 shown in FIG.
When unhulled rice 11 as a raw material is put into the tank, the unhulled rice 11 ascends the supply elevator 5 and flows into the supply tank 4 through the discharge gutter 8. Next, when the on-off valve 51 is pulled to open it as desired, it is dropped little by little into the supply section 48 by the feed roll 49 and the adjustment plate 50, and is supplied from the supply section 48 between the rubber roll 46 and the rubber roll 47.
The rice is removed from the hull and falls into the receiving section 58. The inverted eight-shaped grain board of the receiving part 58 is formed with a very gentle slope to make it compact, but the case 52 is suspended from the frame 45 by leaf springs 53, 53, and the eccentric wheel 55, Since they are swung in the direction of arrow A by the rods 56 and leaf springs 57, even if the slope of the grain board is gentle, both the unhulled rice 11 and the brown rice 12 flow down and are wind sorted by the wind from the cross-flow fan 59. Ru. Therefore, the light rice husks are sucked through the suction port 65, pass through the suction blower 64, and are expelled from the system through the exhaust port 66. The mixed grains of unhulled rice 11 and brown rice 12, which have a high specific gravity, flow laterally through the first grain removal section 62 and are fed to the supply hopper 2 of the swing sorting device 10.
4.

In the swing sorting device 10, when the eccentric wheel 39 is rotated, the angle θ between the rod 44 and the support rod 26 is smaller than the right angle, so the sorting plate 13 moves faster when moving from the front side to the rear side, When moving, move slowly.

Therefore, when the mixed grains of unhulled rice 11 and brown rice 12 are fed from the supply hopper 32 to the sorting plate 13, they are initially in a completely mixed state, but as they are subjected to horizontal or inclined rocking in the front-rear direction, the primary phenomenon is that the specific gravity The heavy brown rice 12 sinks to the lower layer, and the unhulled rice 11, which has a lighter specific gravity, floats to the upper layer of the group of brown rice 12, and only the brown rice 12 that has sunk to the lowest layer comes into contact with the left inclined protrusion 18 and the right inclined protrusion 19.

The brown rice 12 that has come into contact with the left inclined protrusion 18 and the right inclined protrusion 19 gradually moves toward the front wall 16 of the sorting plate 13 due to the inclined protrusions 18 and 19 as a secondary phenomenon, and is transferred to the front half of the sorting plate 13. Deposits slightly thicker. Contrary to this, the rear half of the sorting plate 13 becomes slightly thinner. In this way, the brown rice 12 is deposited slightly thickly on the front half of the sorting plate 13, and the brown rice 12 is deposited on the front half of the sorting plate 13.
When it becomes slightly thinner in the rear half, the unhulled rice 11 floating on the surface of the brown rice 12 in the front half of the sorting plate 13 slides on the uppermost slope and moves toward the rear half of the sorting plate 13.

The state of this secondary phenomenon is adjusted by rotating the screw rod 28. That is, when the screw rod 28 is rotated,
The pieces 31, 32, which are threaded into the counter-threaded grooves 29, 30, move toward and away from each other, so that the arms 36, 37 become inclined or vertical. Therefore, the vertically movable rod 33 is moved up and down by the arms 36 and 37, and the rear support rod 3
8 and 38 move up and down, the front and back inclination of the sorting plate 13 is adjusted.

As a tertiary phenomenon, when the above operation is repeated, the brown rice 12 thickly deposited on the front half of the sorting plate 13 is moved to the left side along the front wall 16 by the action of the tip of the left inclined projection 18. Start moving.

When it starts moving to the left along the front wall 16 on the front side, the thickness of the 12 layers of brown rice gradually increases near the left wall 21, so that a part of the upper layer of the brown rice 12 conversely moves to the rear wall 17 of the sorting plate 13. It begins to flow towards and circulate. Then, the purity of the brown rice 12 is further improved at the left end of the sorting plate 13 to become complete brown rice 12, and the brown rice 12 is taken out from the brown rice outlet 20.
In this case, the movement of the brown rice 12 in the direction of the brown rice outlet 20 is primarily carried out by the tip of the left inclined protrusion 18, but the group of left inclined protrusions 18 is far more effective than the group of right inclined protrusions 19. Due to the large area, the brown rice 12 must be transferred reliably.

On the other hand, the unhulled rice 11 slides over the upper layer of the brown rice 12 on the slope and accumulates on the rear half of the sorting plate 13, but in the rear half of the sorting plate 13, it is affected by the action of the right inclined protrusion 19 as a quaternary phenomenon. It is transferred to the right side of the sorting plate 13. However, due to the action of the right inclined protrusion 19, the unhulled rice 11 is advanced to the right side of the sorting plate 13, and the secondary phenomenon is still being sorted, so the purity of the unhulled rice 11 gradually increases as it advances toward the unhulled rice outlet 22. , finally complete unhulled rice 11
The unhulled rice is then taken out from the unloading port 22.

The above tertiary phenomenon, that is, brown rice outlet 2 of brown rice 12
The movement in the 0 direction and the quaternary phenomenon, that is, the movement of unhulled rice toward the unhulled rice outlet 22, are performed by adjusting the left and right inclinations of the sorting plate 13. That is,
By rotating the adjusting screw 43, the horizontal inclination of the sorting plate 13 is adjusted, and depending on the degree of inclination, the tertiary phenomenon and the quaternary phenomenon can be finely adjusted.
During this time, the mixed grains are accumulated in the center of the sorting plate 13 and swirl around, and the newly supplied brown rice 12 and unhulled rice 11 are only metabolized and never leave the sorting plate 13.

However, the brown rice 1 taken out to the brown rice outlet 20
2 flows into the take-out elevator 6 through the gutter and is taken out.

(Effects) The present invention provides a sorting plate 13 having a rectangular shape when viewed from above.
A front wall 16 is formed on the front edge of the sorting plate 13, a rear wall 17 is formed on the rear edge of the sorting plate 13, a left wall 21 is formed on the left edge of the sorting plate 13, and a right wall 23 is formed on the right edge of the sorting plate 13, The sorting plate 1
A group of left inclined protrusions 18 are formed on the plate surface of the front part except for a part of the rear side of 3, which has a directionality that guides the brown rice to the left when the sorting plate 13 swings. On a part of the side plate surface, a group of directional right-slanted protrusions 19 are formed, the tips of which guide the unhulled rice to the right when the sorting plate 13 swings. 20 brown rice outlets on the front part
Since the unhulled rice outlet 30 is formed in the rear part of the right wall 23 and a mechanism for providing back and forth reciprocating motion is attached to the sorting plate 13, the sorting plate 13 can be sorted by only horizontal back and forth movement. . Furthermore, since there is no exit for the intermediate rice, a mechanism for returning the intermediate rice is not required.

In addition, a huller 3 and a winnower 2 are provided at the upper part of the sorting plate 13, and a supply elevator 5 for supplying unhulled rice to the huller 3 and the brown rice separated by the sorting plate 13 are provided at the side. Since the rice hulling sorting device is equipped with a lifting machine 6 for lifting and lifting grains, there is no returning elevator, so the cost can be reduced.
