[0003]

In the above-mentioned known apparatus, a high-efficiency rice ball rocking and sorting section is formed small in order to match the efficiency of the rice ball rocking and sorting section with the efficiency of the small grain rocking separation section. .
Therefore, the overall efficiency was low. However, since the size of the frame is determined, it is desired to increase the size of the rice ball rocking and sorting section to increase the efficiency. As a measure of the means, the present invention is such that the small-grain oscillating separation unit can be processed in parallel as two upper and lower stages. Then, since the frame can be raised only slightly upward, the floor occupied area can be implemented without change.

[0006] In the rice ball rocking and sorting unit 3, a rice ball sorting net 4 having a high supply side and a low discharge side is installed. A lower net 5 is double-stretched at an interval on the lower surface side of the rice ball sorting net 4, and a ball 6 is stored between the rice ball sorting net 4 and the lower net 5. The rice ball sorting net 4 is formed to have a size that allows grains to pass through but does not allow rice balls to pass through. The lower net 5 is formed by eyes through which the grain passes.

The discharge side of the rice ball oscillating and sorting unit 3 is suspended from the frame 1 by a leaf spring 7, and the supply side of the rice ball oscillating and sorting unit 3 is attached to an upper rotating shaft 9 of a bearing 8. The crank 10 is connected. The lower part of the rice ball rocking sorter 3 is a funnel 11 and 12 is an opening.

At the lower part of the rice ball oscillating sorting section 3, a small oscillating separating section for separating small grains in cereals is provided. According to the present invention, the separating section has an upper and lower two-stage structure, The dynamic separation unit 13 and the lower-stage small-grain swing separation unit 14 are provided. Therefore, the opening 12 of the funnel 11 has an opening 12 reaching the upper small-grain swing separating section 13 and an opening 1 reaching the lower-grain swing separating section 14.
2 ′.

A small particle separation net 15 having a high supply side and a low discharge side is provided inside the upper small particle swing separation section 13. Since the ball 16 is also provided below the small grain separation net 15, the lower net 1
7 is doubly stretched.

The discharge side of the upper small-grain swing separating section 13 is suspended by a leaf spring 18, and the supply side of the upper small-grain swing separating section 13 is connected to a crank 20 mounted on a lower rotating shaft 19 of the bearing 8.
To join.

The lower small-grain swing separating section 14 has substantially the same structure as the upper small-grain swing separating section 13, except that a crushed separation net 24 is provided below the small-grain separation net 21. A ball 22 and a lower net 23 are also provided below the small-grain separation net 21, and a ball 25 and a lower net 26 are also provided below the crushed-grain separation net 24.

The opening 12 ′ of the funnel 11 communicates with the supply side of the small-grain separation net 21 of the lower small-grain swing separating section 14, and the opening 28 of the lower funnel 27 of the upper small-grain swing separation section 13. Is the crushed separation net 2 of the lower small oscillating separation section 14
4 is open on the supply side. The lower small-grain swing separation section 1
The small particles passing through the small particle separation net 21 of No. 4 are also supplied onto the crushed particle separation net 24.

The opening 30 of the funnel 29 at the lower part of the lower small-grain rocking separation part 14 opens on the bran separation net 32 of the rice flour rocking separation part 31 provided thereunder. The bran separation net 32 is also provided with a high supply side and a low discharge side, and a ball 33 and a lower net 34 are provided below the bran separation net 32. 35 is a funnel, 36
Is an opening.

The discharge side of the lower small-grain swing separating section 14 is suspended from the frame 1 by a leaf spring 37, and the supply side thereof is connected to a crank 40 mounted on an upper rotating shaft 39 of a bearing 38. . The discharge side of the rice flour swinging separation unit 31 is suspended from the frame 1 by a leaf spring 41, and its supply side is connected to a crank 43 attached to a lower rotating shaft 42 of a bearing 38. 44 is a passive pulley.

[0015]

When the passive pulley 44 is rotated by the motor, the crank 10, the crank 20, the rice flour swing separating section 3
1. The small-grain separation net 15 cranks, and the discharge side is suspended by a leaf spring 7, a leaf spring 18, a leaf spring 37, and a leaf spring 41, respectively. 13, the lower small-grain rocking separation unit 14, and the rice flour rocking separation unit 31 rock simultaneously.

Then, when the polished rice is supplied from the supply hopper 2, while the rice is flowing on the rice ball sorting net 4 of the rice ball oscillating sorter 3,
The polished rice is separated into large rice balls and polished rice (sized), the rice balls are taken out to the left in the figure, and the sized rice flows down in the funnel 11. Since the separated sized granules have a large amount, they are divided into two, one of which flows on the small-grain separation net 15 of the upper small-grain swing separation unit 13 from the opening 12, and the other flows on the small-grain swing separation unit 14 below the opening 12 ′ , And are processed in parallel, only the sizing is taken out to the left, and the small particles are supplied together to the lower crushed separation net 24 in the lower oscillating separation unit 14. .

The small particles flowing down the funnel 29 of the lower small-grain rocking / separation unit 14 are passed through the opening 30 to the rice flour rocking / separation unit 31.
Is supplied onto the rice bran separation net 32 and shaken to separate the rice bran flour.

[0018]

Conventionally, a frame having a supply hopper attached thereto, a rice ball oscillating sorting section provided at an upper position in the frame, and a small grain oscillating section provided below the rice ball oscillating sorting section. A dynamic separation unit, a crushed particle oscillating separation unit provided below the small-particle oscillating separation unit, and a rice flour oscillating separation unit provided below the crushed particle oscillating separation unit are known, In the above-mentioned known apparatus, a high-efficiency rice ball rocking and sorting section is formed small in order to match the efficiency of the rice ball rocking and sorting section with the efficiency of the small grain rocking separation section.
Therefore, the overall efficiency was low.

However, according to the present invention, the frame 1 to which the supply hopper 2 is mounted, the rice ball rocking and sorting unit 3 provided at an upper position in the frame 1, and the rice ball rocking and sorting unit 3 A small-grain oscillating separation unit provided at the lower part of the crushed-grain oscillating separation unit provided at the lower part of the small-grain oscillating separation unit; The opening for discharging the separated sizing of the rice ball oscillating sorter 3 is divided into a plurality of openings 12 and 12 ′, and the small oscillating separator is formed as a plurality of upper and lower stages. An upper-stage small-grain swing separation unit 13 and a lower-stage small-grain swing separation unit 14 are formed, and the opening 12 and the upper-stage small-grain swing separation unit 13 are combined with the opening 12 ′ and the lower-stage small-grain swing separation unit 14. Since the grain sorting apparatuses are connected to each other, the bran ball rocking sorting section 3 is connected to the frame 1
Even if the size is full, since the upper and lower small-grain swing separation sections 13 and 14 can select the upper and lower two-grain swing separation section 13,
