Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting plate for an oscillating grain sorting device.

The present invention is a result of the intensive development of a newly developed oscillating grain sorting device, particularly regarding the sorting plate.

The swing-type grain sorting device in a conventionally known hulling device has a structure in which brown rice is taken out from one side of the discharge side, unhulled rice is taken out from the other side of the discharge side, and intermediate rice is taken out from the middle.

In the present invention, brown rice is taken out from the left and right sides of a sorting plate, unhulled rice is taken out from the other side of the left and right sides, and intermediate rice is not taken out. One brown rice outlet is provided on the left and right sides of a rectangular sorting plate with an oblique shape, and an unhulled rice outlet is provided on the other left and right sides, and the brown rice is moved toward the brown rice outlet on the plate surface of the sorting plate. A sorting plate of a swing-type grain sorting device formed by press-forming a brown rice section protrusion and a paddy rice section protrusion that moves the unhulled rice toward the unhulled rice outlet, and the front, rear, left, and right ends of a single metal plate that is continuous in all four directions. The front wall, rear wall, left and right walls are formed by bending the parts upward at right angles and standing up.
A brown rice outlet is formed by cutting out one side of the left and right walls, and an unhulled rice outlet is formed by cutting out the other side, and brown rice is moved toward the brown rice outlet on the surface of the metal plate excluding the upright portion. The gist of the present invention is to have a structure of a sorting plate of a swing-type grain sorting device, which is formed by pressing and forming a brown rice section protrusion and an unhulled rice protrusion that moves the unhulled rice toward an unhulled rice outlet.

FIG. 1 is a schematic diagram of the entire conventionally known hulling device, in which A is a supply hopper into which unhulled rice a is input, B is a hulling section provided at the bottom of the supply hopper A; A pair of rubber rolls C1C are pivoted. A wind sorting section is provided at the bottom of the hulling section B, where the lightweight rice husks C are wind sorted, and the hulled brown rice and unhusked rice A remaining after the hulling are mixed and guided to the side. , flows into the lower part of the side elevator E. A tank F, commonly called an adjustment tank, is suspended from the upper end of the elevator E by a spring, and moves up and down depending on the storage amount. This vertical movement causes the valve at the outlet of the supply hopper A to open and close in conjunction with each other via a wire or the like.

The mixed rice in the adjustment tank F is moved to the swing-type sorting device G that is the object of the present invention, where it is separated, and the unhulled rice a is returned to the supply hopper A by the thrower H, and the brown rice is used as finished rice. It flows into the elevator ■ and is taken out. Central America is elevating mE
Move to. The deficiencies of the prior art are as follows: (a) Since the supply hopper A is located high, it is difficult to supply the unhulled rice a.

Since grain and intermediate rice flow into the elevator E from the swing type sorting device G, it is necessary to automatically adjust the amount of rice supplied to the hulling section B of the supply hopper A using the adjustment tank F suspended by a spring. , the structure becomes more complex and the height increases.

C. In order to return the unhulled rice from the swing type sorter GtG to the supply hopper A, a return thrower H is required.

FIG. 13 shows a state in which brown rice section protrusions 72 and unhulled rice section protrusions 74 are simultaneously formed by press working on a sorting plate 70 made of a single stainless steel plate. When the sorting plate 70 is formed from one stainless steel plate in this way, the sorting plate 70
can be installed over the entire surface without distortion.

In actual use, there is much more brown rice than unhulled rice, so the area of the front plate 85 on which the brown rice part protrusion 72 is formed is much larger than the rear plate 86 part on which the unhulled rice part protrusion 74 is formed. do.

The sorting plates 70 are provided in multiple stages as shown in FIG. A distribution device 87 reaching each stage is provided on the upper part of the sorting plate 70 (

The lower end 104 of the guide pipe 100 is the opening at the upper part of the socket 105 that reaches the top of the sorting plate 705. 106 is a return opening formed at the lower part of the elevator I.

107 is a discharge gutter leading to the supply tank 8, 108 is a filling hopper, 109 is an immature 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 bottom of the elevator l, the elevator @1 is raised A and discharged into the discharge gutter 107.
It flows into the supply tank 8, is fed out little by little by the feeding roll 14, collides with the inclined plate 15, is fed along the slope of the inclined plate 15 to the middle of the rubber rolls 16.17, and is fed between the rubber rolls 16.17. The rice is hulled and discharged to the discharge side -18. This rice hulled material collides with the diffuser 19, and the diffuser 1
9, the rubber roll 16.1 jumps over the mouth edge 26 and hits the reflective plate 27, and when reflected on the reflective plate 27, the rubber roll 16.1
7, flows into the diffusion chamber in the diffusion tube 24.25, and is supplied to the inclined guide plate 28.29. The inclined guide plates 28 and 29 are both installed at a gentle slope, and the grains supplied thereto do not flow down under their own weight. The selection case 111 vibrates violently in the direction of the arrow along with the inclined guide plates 28 and 29, and the inclined guide plates 28 and 29 smoothly flow the hulled materials even on a gentle slope, and at the same time, spread the hulled materials in the width direction.
It is made to flow uniformly into the wind selection chamber 33. Since the wind sucked from the suction port 32 is blown into the wind selection chamber 33 by the cross-flow windmill 30, the lightweight rice grains fJc are blown up into the suction path 34, sucked by the blower 35, and discharged.

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

When the storage amount in the hopper 36 reaches a certain level, the arm 39 moves downward against the elasticity of the spring 40, and the on-off valve 38 opens around the shaft 37, distributing grains uniformly across the entire width. let it fall. The fallen mixed rice is supplied to a distribution device 87.

Since the distribution device 87 is violently vibrated in the front-rear direction via the rod 53 due to the rotation of the eccentric cam 52 of the drive shaft 51, the vibration is diffused to the full extent in the width direction of the distribution device 87.
When these flow from one end 88 toward the other end 89,
It jumps over the weir 9o and spreads evenly, and is partitioned by a partition plate 91 provided at the other end 89 to form each outlet 9.
2 and is supplied to each sorting plate 7o.

In the sorting plate 70, when the drive shaft 51 rotates, the eccentric cam 52 rotates, and the mounting base 48 is reciprocated in the horizontal direction as shown by the 12th rffl arrow via the rod 53 attached to the eccentric cam 52. Since the angle θ between the swinging arm 49 supporting the mounting base 48 and the rod 53 is smaller than the right angle, when the sorting plate 7o moves forward due to quick return, it moves at a slow speed, but it moves backward. When moving, move quickly at a ratio of 1:1.01 to 1.2.

Therefore, the unhulled rice a supplied to the sorting plate 70 from the outlet 92
The mixed rice of brown rice and brown rice is separated as shown in Fig. 15 by the sorting plate 70 moving back and forth. It flows into the inlet 93 and raises the extraction 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 unhulled rice section projection 74 and flows out from the unhulled rice outlet 80 to the unhulled rice outflow gutter 84, and flows from the unhulled rice outflow gutter 84 to the return port 106 of the elevator 1, and the supplied unhulled rice a join with.

When the work is completed, the separating action of the sorting plate 70 ceases, and both the unhulled rice a and brown rice flow out from the unhulled outlet 80 to the unhulled rice outflow gutter 84, so the switching valve 95 is moved to the position indicated by the solid line in FIG. By switching to , the water can be stored in the storage tank 98 via the return gutter 96 . The stored mixed rice flows into the receiving port 105 by opening the opening/closing valve 101, and is supplied from the receiving port 105 to the uppermost sorting plate 70 where it is sorted.

The present invention provides a brown rice take-out lower 1 on the left and right sides of a rectangular sorting plate 70 formed of a single metal plate continuous in all four directions, and a paddy rice take-out port 80 on the other left and right sides. A rocking grain sorting device is formed by pressing on the plate surface of 70 a brown rice portion projection 72 for moving the brown rice in the direction of the brown rice take-out lower 1 and a hull rice portion projection 74 for moving the unhulled rice in the direction of the unhulled rice take-out port 80. Since the rectangular sorting plate 70 is made of one metal plate that is continuous on all sides, it is different from the one formed of two plates, the front plate and the rear plate, because it is completely flat and free of distortion. This allows for good sorting. In addition, the front, rear, left and right end portions of a single metal plate that is continuous in all directions are bent upward at right angles to stand up the front wall 113, rear wall 114, left and right walls 7
5.79, cut out one side of the left and right walls 75.79, cut out the other side of the brown rice removal lower 1 to form the unhulled rice removal port 8o, and exclude the standing portion of the metal plate. A sorting plate of a mobile type grain sorting device, which is formed by pressing a brown rice collection protrusion 72 for moving brown rice in one direction of a brown rice extraction lower 1 direction and a paddy rice part protrusion 74 for moving unhulled rice in the direction of the unhulled rice extraction port 8o. Because of this structure, it is easy to manufacture and can be formed at low cost, and the bent portions around the four peripheries have a reinforcing effect, resulting in a product with even fewer surfaces.
