A discharge gutter 8 of the supply elevator 5 is connected to the supply tank 4 of the hulling section 3, and a brown rice outlet of the swing type grain sorting section 1 is connected to the elevator 6 for taking out.

The oscillating grain sorting section 1 is provided with a oscillating sorting device 1O consisting of a sorting plate 13 and a swinging mechanism in a space inside a frame 9 made of angle steel. Unlike the original, it is a mixed rice (medium grain) of 11 grains of unhulled rice and 12 parts of brown rice.
It separates only unhulled rice 11 and brown rice 12 without producing it.

To explain its detailed structure, 13 is a sorting plate of the present invention, and the sorting plate i13 of the embodiment has a horizontal width 15 longer than a front-rear width 14 as shown in FIG. It is long on the left and right sides and has a rectangular shape. ``At the front edge of the sorting plate 13, front walls 16 are formed across the entire width, and similarly, at the rear edge of the sorting plate 13, a rear wall 17 is formed over the entire width. Therefore, on the front plate surface of the sorting plate 13, a group of left inclined protrusions 18 whose tips are directed toward the left if it is the left side of the left side is formed on the entire plate surface, and on the rear side of the sorting plate 13. On the board surface, a group of 19 right-slanted protrusions facing rightward on the right side of the left and right sides are formed over the entire board surface.

The left inclined projection 18 and the right inclined projection 19 are both formed in a direction to move the grain toward the front wall 16.

A brown rice outlet 20 is formed in the left front part of the sorting plate 13, and the rest is closed by a left wall 21. A hulled rice outlet 22 is formed in the right rear part of the sorting plate 13, and the rest is blocked by the right wall 23. Reference numeral 24 is a supply hopper that receives grains falling from the wind sorting section 2 above. 22 is provided at the front position of the side provided with.

Thus, the lower end portion of the front support rod 26 is pivoted 27 to the front side of the support base 25 placed on the floor. A screw punch 28 is pivoted to the rear side of the support base 25 so that it can only rotate freely. Opposite screw grooves 29 and 30 are respectively carved on the left and right sides from the center of the screw rod 28, and a piece 31 is screwed into the screw groove 29 and a piece 32 is screwed into the opposite screw groove 30. A vertically movable rod 33 is provided at a position below the screw punch 28 so as to be movable up and down, and bosses 34 and 35 are fitted to the vertically movable rod 33 so as to rotate freely, and the top 31 and the boss 3
4 is connected with the arm 36, and the piece 32 and the boss 35 are connected by the arm 36.
are connected by an arm 37. The lower end of the rear support rod 38 is pivotally attached to the vertically movable rod 33, and the mounting base 40 is pivotally attached to the upper ends of the front support rod 26 and the rear support rod 38.

Therefore, the sorting plate 13 is pivoted on the upper surface of the left side of the mounting base 40 via the pivot attachment part 41, and the top 4 is mounted on the right end of the mounting base 40.
2 is fixed with a shaft, and a vertical adjustment screw 43 is mounted on the top 42, and the upper end of the adjustment screw 43 is engaged with the lower end of the sorting plate 13.

39 is an eccentric wheel, and 44 is a rod, and the angle 0 between the rod 44 and the support rod 26 is smaller than a right angle.

Next, the structures of the wind sorting section 2 and the hulling section 3 provided at the upper part of the swinging type grain sorting section @li1 will be explained. Reference numeral 45 designates the frame 45, which is installed above the frame 9 of the swinging type grain selection section 1. The frame 45 is formed in such a manner that it can be placed snugly thereon, and a wind selection section 2 is provided inside the frame 45 . A pair of rubber rolls 46 and 47 are mounted inside the hulling part 3 in a diagonally vertical relationship, and a pair of rubber rolls 46 and 47 are mounted on the hulling part 3 at a position offset to one side of the upper part of the frame 45. and rubber roll 4
A supply section 48 for supplying unhulled rice 11 faces between 7 and 7.

49 is a feed roll, 50 is an adjustment plate, and 51 is an on-off valve.

A wind selection section 2 is provided within the frame 45. To explain the structure of the wind selection section 2, the entire structure is formed inside the case 52, the upper end of which is fixed to the frame 45, and the lower end of the plate/henne 53 is fixed to the case 52 and attached to the rotating shaft 54. A rod 56 of an eccentric ring 55 is fixed to the case 52 via a leaf spring 57.

Therefore, when the eccentric wheel 55 rotates, the rod 56 and the leaf spring 5
7, the case 52 is reciprocated in the direction of arrow A. A receiving part 58 is formed below the rubber roll 46 and the rubber roll 47 on the upper surface of the inside of the case 52, and a cross-flow fan 59 is installed below the receiving part 58. Cross flow fan 59
An air suction port 60 is provided above the cross-flow fan 59, and a wind selection chamber 61 is formed at the outlet of the cross-flow fan 59. 62 is the first grain removal section, and 63 is a waste grain removal section. Further, 64 is a suction blower, 65 is a suction port, and 66 is an exhaust port.

Next, we will discuss the effect.

When raw rice 11 is put into the charging hopper 24 of the supply elevator 5 shown in FIG. Next, when the on-off valve 51 is pulled and opened 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, and the rice is removed from the hull. and falls into the receiving section 58. The inverted grain board of the receiving part 58 is formed with a very gentle slope, but the case 52 is suspended from the frame 45 by leaf springs 53, 53, and the eccentric wheel 55, rod 56, and plate Since they are swung in the direction of arrow A by the spring 57, both the unhulled rice 11 and the brown rice 12 flow down even if the slope of the grain flow board is gentle, and are air-sorted by the wind from the cross-flow fan 59. Therefore, the light rice husks are sucked through the suction port 65, pass through the suction blower 64, and are discharged from the system through the exhaust port 66.

The mixed grains of unhulled rice 11 and brown rice 12, which have a large specific gravity, flow laterally through the first grain removal section 62 and flow into the supply hopper 24 of the swing sorting device 10.

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 from the rear to the front, move slowly.

Therefore, when mixed grains of unhulled rice 11 and brown rice 12 are supplied from the supply hopper 32 to the sorting plate 13, the unhulled rice 11 and brown rice 12 are
is in a completely mixed grain state, but in this state it is subjected to horizontal or tilted rocking in the front-rear direction, so as for the next development, brown rice 12 with heavy specific gravity sinks to the bottom layer, and unhulled rice 11 with light specific gravity is divided into groups of brown rice 12. Brown rice that floated to the top layer and sank to the bottom layer 1
2 is in contact with the left inclined protrusion 18 and the right inclined protrusion 19.

In this way, the bottom layer of brown rice 12 that has come into contact with the left inclined protrusion 18 and the right inclined protrusion 19 is influenced by the inclined protrusions 18 and 19, and as a secondary phenomenon, gradually moves to the front wall 16 of the front edge of the sorting plate 13. , and is deposited relatively thickly on the front half of the sorting plate 13. As a result, the rear half of the sorting plate 13 becomes relatively thin. In this way, the brown rice 12 is separated from the sorting board 13.
When the paddy rice 11 floats on the surface of the brown rice 12 on the front half of the sorting plate 13, it accumulates relatively thickly on the front half of the sorting plate 13 and becomes relatively thin on the rear half of the sorting plate 13. and slide to the rear half of the sorting plate 13.

The state of this secondary phenomenon is adjusted by rotating the screw pestle 28. That is, when the screw pestle 28 is rotated, one opposite cap groove 29 is formed.
．． The pieces 31, 32, each screwed into the arm 30, move towards and away from each other, so that the arms 36, 3
7 can be inclined or vertical. Therefore, the vertically movable rod 33 is moved up and down by the arm 36.37, and the rear support rod 38.38 is moved up and down, thereby adjusting the front and rear inclination of the sorting plate 13.

As a tertiary phenomenon, when the above operation is repeated, the brown rice 12 that is thickly deposited on the front half of the sorting plate 13 becomes
Due to the action of the tip of the left inclined projection 18, it starts moving to the left along the front wall 16 on the front side. At this time as well, the brown rice 12 that is in contact with the inclined protrusion 18.1 on the plate surface of the sorting plate 13 is
As it continues to be subjected to the sorting action described above while moving to the left, the thickness of the brown rice 12 layer gradually increases as it moves along the front wall 16, and therefore, a part of the upper layer of the brown rice 12 conversely passes through the sorting plate 13. It will start flowing towards the second half of the brown rice.
When the brown rice 2 reaches the left end of the sorting plate 13, the purity is further improved and only complete brown rice 12 is taken out to 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 mainly carried out by the tip of the left inclined protrusion 18, but the left inclined protrusion 18 has a much larger area than the right inclined protrusion 19. Therefore, the brown rice 12 must be transferred reliably.

On the other hand, the unhulled rice 11 slides on the upper layer of the brown rice 12 on the inclined surface and is deposited 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, the unhulled rice 11 becomes complete and is taken out from the unhulled rice outlet 22.

The above-mentioned tertiary phenomenon, that is, the movement of the brown rice 12 toward the direction of the brown rice outlet 20, and the fourth phenomenon, that is, the movement of the unhulled rice toward the unhulled rice outlet 22, is 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.

The brown rice 12 taken out to the brown rice take-out port 20 flows into the take-out elevator 6 through the gutter and is taken out.

A conventional hulling device has a structure in which a wind sorting section is provided on the floor, a hulling section is provided above the wind selection section, and a swing type grain sorting section is provided at the side of the hulling section. In addition, no matter what type of device it is, it always has a mechanism for processing intermediate grains, has a very large structure, and is quite expensive.

The present invention has improved on this point, and includes a sorting plate that swings back and forth, has a brown rice outlet on one side of the left and right sides, a paddy rice outlet on the other side of the left and right sides, and does not have an intermediate grain outlet. A hulling device having a oscillating grain sorting unit provided with a wind sorting part for rice hulling, a rice hulling part in the upper part of the wind sorting part, and an elevator on the side, and
It swings back and forth, and on the front plate surface, there is an inclined protrusion that is higher on the front side and slopes toward the brown rice outlet formed on one side of the left and right sides, and on the rear plate surface Similarly, a tilted protrusion is provided which is higher on the front side and is slanted toward the unhulled rice outlet formed on the other left and right sides, forming a swinging type grain sorting section having a sorting plate that does not have an intermediate grain outlet.
