Description

[Detailed description of the invention] The present invention relates to a rice hulling device.

The gist of the present invention is the overall basic configuration, but since each part uses a device that has improved the conventional drawbacks, the configuration of each part will be explained in sequence.

Conventional hulling equipment 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 on the side of the hulling section. It was also very large and quite expensive.

The present invention improves this point by providing a wind sorting section on the upper part of the swing type grain sorting section provided on the floor, a hulling section on the upper part of the wind sorting section, and an elevator on the side. In a hulling device in which a wind sorting section is provided above a swinging type grain sorting section provided on the floor, a hulling section is provided above the wind screening section, and an elevator is provided on the side. The above-mentioned elevator has a very small structure and is considerably inexpensive by having a structure of the hulling device consisting of two, a supply elevator and a take-out elevator.

To explain with the drawings, 1 is a swinging grain sorting section, 2 is a wind sorting section provided above the swinging grain sorting section 1, and 3 is a hulling section.
The hulling section 3 is attached to the upper part of the winnowing section 2. 4 is a supply tank for the hulling section 3; 5 is a supply elevator for the hulling section 3; 6

A take-out elevator 6 is provided, 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 take-out port of the oscillating grain sorting section 1 is connected to the take-out elevator 6.

The oscillating grain sorting section l is provided with an 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, and the sorting plate 13 is different from the conventional one. 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, reference numeral 13 denotes a sorting plate of the present invention, and the sorting plate 13 of the embodiment has a horizontal width 15 longer than a front-back width 14 as shown in FIG. It has a rectangular shape with long sides on the left and right sides. Sorting board 13
At the front edge of , front walls 16 are formed across the entire width, and similarly,
A rear wall 17 is also formed at the rear edge of the sorting plate 13 over the entire width. Therefore, on the front plate surface of the sorting plate 13, there is a left inclined protrusion 1 whose tip is directed to the left if it is the left of the left or right sides.
Eight groups are formed on the entire plate surface, and on the rear plate surface of the sorting plate 13, a group of 19 right-slanted protrusions, which are oriented rightward on the right side of the left and right sides, are formed on the entire plate 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. An unhulled 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 the grains falling from the upper wind sorter g2. 22 is provided at the front position of the side provided with.

Thus, the lower end 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 both left and right sides from the center of the screw punch 28, and a piece 31 is provided in the screw groove 29, and a counter screw groove 30 is provided in the screw groove 29.
Screw together the piece 32. At the lower position of the screw pestle 28,
A vertically movable rod 33 is provided to be movable up and down, bosses 34 and 35 are fitted to the vertically movable rod 33 in a rotational manner only, and an arm 36 connects the top 31 and the boss 34. 3
5 through 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 upper left side of the mounting base 40 (this +1 shaft attachment part 41
The sorting plate 13 is pivoted through the mounting plate 40, the top 42 is pivoted to the right end of the mounting base 40, and the adjustment screw 43 perpendicular to the top 42 is screwed together to adjust the adjustment! The upper end of the lI stacking rod 43 is engaged with the lower end of the sorting plate 13.

39 is an eccentric wheel, 44 is a mouth/end;
The angle 0 of the support rod 26 is 1° smaller than the right angle.
To explain the structure of the frame 45, the frame 45 is formed to be placed exactly above the frame 9 of the swing type grain sorting section 1, and the inside of the frame 45 (this is the wind sorting section 2).
is provided. The hulling part 3 is placed at a position on one side of the upper part of the frame 45. Inside the hulling part 3, a pair of rubber rolls 46 and 47 are pivoted in a diagonally vertical relationship. 'It is located between the mull roll 46 and the rubber roll 47 (1/1 facing the supply section 48 that supplies the unhulled rice 11). 49
t-h feeding roll; 50 is a regulating plate; and 51+ is an on-off valve.

Inside the frame 45
T will be ignored. Structural tips of wind selection section 2 1. To explain this, the lower end of the plate/branch 53 and 53, which are entirely formed inside the case 52 and the upper end of the frame No. 45 is fixed, is connected to the lower end of the case 52. The opening of the eccentric wheel 55, which is the rotational shaft 54 and the diameter ζ, is fixed to the case 52 via a plate/hook 57.

Therefore, when the eccentric wheel 55 rotates, the case 52 is reciprocated in the direction of the arrow A via the opening 56 and the leaf spring 57. A receiving part 58 is formed below the rubber roll 46 and the rubber roll 47 on the upper surface of the case 52 @b, and a cross-flow fan 59 is attached below the receiving part 58 . An air suction port 60 is provided above the cross-flow fan 59, and an air selection chamber 61 is formed at the outlet of the cross-flow fan 59. 6
2 is the first grain removal part, and 63 is a waste grain removal part. Also, 6
4 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 portion 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 ring 55, opening 1. Do56, board/
Since they are swung in the direction of arrow A by the wedges 57, both the unhulled rice 11 and the brown rice 12 flow down even if the slope of the grain board is gentle, and are subjected to the wind from the cross-flow fan 59 to be air-sorted.

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 1.1 and brown rice 12, which have a high specific gravity, flow laterally through the first grain removal section 62 and are passed through the swing sorting device IO.
into the feed hopper 24.

In the swing sorting device 1o, when the eccentric wheel 39 is rotated, the angle θ between the rod F'44 and the support rod 26 is smaller than a right angle, so
The sorting plate 13 moves quickly when moving from the front side to the rear side, and moves slowly when moving from the rear side to the front side.

Therefore, when mixed grains of unhulled rice 11 and brown rice 12 are supplied to the sorting plate 13 from the supply hopper 2 32, 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 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 I8 and I9, and as a secondary phenomenon, the brown rice 12 gradually forms on the front wall of the front edge of the sorting plate 13. 16, 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 punch 28 is rotated, the opposite screw groove 29
．． The pieces 31, 32, which are respectively screwed into 3o, move towards and away from each other, so that the arms 36, 3
7 can be inclined or vertical. Accordingly, the vertically movable rod 33 is cut downward by the arm 36.37, and by moving the rear support rod 38.38 up and down, the front and rear inclination of the sorting plate 13 is adjusted.

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 protrusions 18 and 19 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 3, 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 force of the unhulled rice 11 slides on the upper layer of the brown rice 12 on the slope 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.

Conventional rice hulling equipment has a structure in which a wind sorting section is provided on the floor, a hulling section is provided in the second part of the wind sorting section, and a swing type grain sorting section is provided on the side of the hulling section. , the structure was very large and the price was also quite expensive.

The present invention is an improvement on this point, in which a wind sorting section is provided above the swinging type grain sorting section provided on the floor, a hulling section is provided above the wind sorting section, and an elevator is provided on the side. In a hulling device in which a wind sorting section is provided above a swinging type grain sorting section provided on the floor, a hulling section is provided above the wind screening section, and an elevator is provided on the side. The structure of the elevator can be made very small and the price can be made considerably low by constructing the hulling device in two parts: a supply elevator and a take-out elevator.
