Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a hulling device. The gist of the present invention is the overall basic configuration.

(Prior art) The conventionally known Japanese Patent Application Laid-open No. 57-65333 discloses a swing type grain sorting section surrounded by a frame placed on the floor, a feeding elevator and a circulation system provided on the sides thereof. A device consisting of a rice lift and a thrower for taking out finished rice is described.

In addition, the conventionally known Japanese Utility Model Publication No. 55-58236 and Japanese Utility Model Publication No. 59-6892 disclose a swing type grain sorting section surrounded by a frame placed on the floor, and a Finished grains sorted by a sorting section, a huller head provided in the frame, a supply elevator for supplying unhulled rice to the huller head provided on the side thereof, and the swinging grain sorter. It describes a hulling device that consists of a lift for lifting rice and a lift for lifting rice.

(Problems to be Solved by the Invention) Since the former does not describe a hulling device, special ingenuity is required for each part in order to make it a hulling device. The latter has a swing type grain sorting section, a wind sorting section, and a hulling head, but since these are provided on one frame, it is not easy to transport. In addition, the positional relationship between the wind selection section and the huller head is such that the wind selection section is right next to the huller removal head. Therefore, even if the air selection section is capable of removing lightweight foreign matter, it cannot separate the first and second particles, which is the original performance of the air selection section. The wind sorting section must be located below the huller head. In addition, it has a structure in which the swinging grain sorting section, the wind sorting section, and the hulling head are installed in one frame, but in particular, the hulling head has a mechanism that rotates two rubber rolls at different speeds, Since it is necessary to provide a mechanism for constantly swinging one of the rubber rolls while maintaining accuracy, it is difficult to provide it within a single frame. In addition, since the rubber roll wears out quickly and must be replaced, it is necessary to have a structure that allows for easy replacement.

(Object of the Invention) The present invention provides an overall basic structure that is easy to transport. Another object of the present invention is to configure the first and second winding sections to be separable. Another object of the present invention is to maintain precision in the structure of the huller head. Another object of the present invention is to provide an easy-to-replace rubber roll.

(Means for Solving the Problems) Therefore, the present invention provides a frame 9 placed on a floor.

The oscillating grain sorting section 1 is provided with a oscillating sorting device 10 consisting of a sorting plate 13 and a swinging mechanism in a space inside a frame 9 made of angle steel. Unlike the conventional method, this method separates only unhulled rice 11 and brown rice 12 without producing a mixed rice (intermediate grain) of unhulled rice 11 and brown rice 12. A frame 9 made of angle steel is higher than the swinging grain sorting section 1 and surrounds the upper part of the swinging grain sorting section 1.

To explain its detailed structure, reference numeral 13 denotes a sorting plate of the present invention, and the sorting plate 13 of the embodiment has a width of 14 in the left and right directions, which is wider than the front and back width 14, as shown in FIG.
No. 5 is longer, and its bird's-eye view shows a rectangular shape that is long on the left and right sides. At the front edge of the sorting plate 13, there is a front wall 1.
6 is formed over the entire width, and similarly, a rear wall 17 is formed over the entire width at the rear edge of the sorting plate 13. 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.

There is a brown rice outlet 2 on the front left side of the sorting plate 13.

Thus, the lower end of the front support rod 26 is attached to the front side of the support 25 of the frame 9 placed on the floor.
do. A screw rod 28 is pivotally attached to the rear side of the support base 25 so that it can only rotate freely. Opposite thread grooves 29 and 30 are carved in the threaded rod 28 from the center on both the left and right sides, respectively.
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 below the screw rod 28 so as to be movable up and down, and bosses 34 and 35 are fitted to the vertically movable rod 33 only in rotation. The top 32 and the boss 35 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.

Thus, the sorting plate 13 is pivotally attached to the upper surface of the left side of the mounting base 40 via a shaft attachment part 41, a block 42 is pivoted to the right end of the mounting base 40, and an adjustment screw 43 perpendicular to the frame 42 is fixed to the right end of the mounting base 40. are screwed together, and the upper end of the adjusting 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 θ between the rod 44 and the support rod 26 is smaller than a right angle.

Next, the structure of the wind sorting section 2 provided on the upper part of the swinging grain sorting section 1 will be explained. Reference numeral 45 denotes its frame, which is placed tightly above the frame 9 of the swinging grain selection section 1. The wind selection section 2 is provided inside the frame 45.

The huller head 3 is placed at a position on one side of the upper part of the frame 45.

The huller head 3 has a pair of rubber rolls 46, 4 inside.
7 are pivoted in a diagonally vertical relationship, and a supply section 48 for supplying unhulled rice 11 faces between the rubber rolls 46 and 47. 49 is a refill roll,
50 is a control plate, and 51 is an on-off valve.

To explain the structure of the wind selection section 2, the entire structure is formed inside a case 52, and the lower ends of leaf springs 53, 53 whose upper ends are fixed to the frame 45 are attached to the case 5.
2 and attached to the rotating shaft 54.
The rod 56 of No. 5 is connected to the case 52 via the plate spring 57.
It is fixed at

Therefore, when the eccentric wheel 55 rotates, the rod 56.

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.

A swing type grain sorting section 1 surrounded by a frame 9 is placed on the floor, a wind sorting section 2 surrounded by a frame 45 is placed on the frame 9, and a hulling head 3 is placed on the frame 45. A supply elevator 5 for supplying unhulled rice to the huller head 3 and a take-out elevator 6 for lifting the finished rice sorted by the swing type grain sorting section 1 are placed on the side thereof. Once installed and connected, the transport assembly is complete.

Therefore, when the raw rice 11 is put into the loading hopper of the supply elevator 5 shown in FIG.
rises in the supply elevator 5 and flows into the supply tank 4 via the discharge gutter 8. Next, when the on-off valve 51 of the supply tank 4 is pulled to open it as desired, the liquid is dropped little by little into the supply section 48 by the feed roll 49 and the adjustment plate 50, and is then supplied from the supply section 48 between the rubber roll 46 and the rubber roll 47. The unhusked rice is removed, the hulled rice is removed, and the rice falls into the receiving section 58.

The inverted eight-shaped grain board of the receiving part 58 is formed with a very gentle slope, but the case 52 that fixes the grain board has leaf springs 53, 53 attached to the frame 45.
It is suspended with an eccentric wheel of 55 and a rod of 5.
6. Since it is vibrated in the direction of arrow A by the plate spring 57, even if the slope of the floating grain plate is gentle, the unhulled rice 1
1. Brown rice 12 flows down together, cross flow fan 59
They are sorted by the wind.

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, and the rice husks, which have a large specific gravity, are unpaddy rice 11 and brown rice 12.
The mixed grains flow laterally through the first grain removal section 62 and into the receiving hopper 24 of the oscillating sorter 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, and when moving from the rear side to the rear side. When moving forward, move slowly.

Therefore, when mixed grains of unhulled rice 11 and brown rice 12 are fed from the supply hopper 32 to the sorting plate 13, the unhulled rice 11 and brown rice 12 are completely mixed grains. As a result, as a primary phenomenon, brown rice 12 with a heavy specific gravity sinks to the lower layer, and unhulled rice 11 with a lighter specific gravity floats to the upper layer of the group of brown rice 12. It comes into contact with the right inclined projection 19.

In this way, the lowermost 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. move in the direction of
A relatively thick layer is deposited 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, when the brown rice 12 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, the brown rice 12 on the front half of the sorting plate 13 accumulates relatively thickly and becomes relatively thin on the rear half of the sorting plate 13.
The unhulled rice 11 floating on the surface of the plate 2 slides on the inclined surface of the brown rice 12 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. At this time as well, the inclined protrusion 1 on the plate surface of the sorting plate 13
The brown rice 12 in contact with the surfaces 8 and 19 continues to be subjected to the sorting action described above while moving to the left, so as it moves along the front wall 16, the brown rice 12 gradually
The layer increases in thickness, so that part of the upper layer of the brown rice 12 flows backwards toward the rear half of the sorting plate 13, and when the brown rice 12 reaches the left end of the sorting plate 13, the purity is low. Only the improved 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 primarily 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 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 accumulate in the center of the sorting plate 13 and rotate around, and the newly supplied brown rice 12 and unhulled rice 11 are only metabolized and never reach the sorting plate 13.
Don't go outside.

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.
