Description

[Detailed description of the invention] The present invention relates to an oscillating grain sorting device.

Conventionally, in the oscillating grain sorting device attached to the hulling device,
In order to remove immature grains mixed in the brown rice that is separated and discharged, an immature grain sorting section is installed in the brown rice take-out gutter. At most, only about 10 to 30% of immature grains are removed, and when it is packed into bags as finished rice,
Immature rice was further removed using a separate rotary removal device.

However, the grain sorting device of the present invention can also remove immature grains, which could not be done with conventional grain sorting devices, and will be explained below.

To explain with the drawings, this is an embodiment incorporated into a hulling device, in which 1 is an elevator for loading unhulled rice, and a guide roll 2 is installed below -j1.

The swing type diffuser 22 is elastically supported by a leaf spring 27. Instead of the leaf spring 27, a swing support rod may be used.

29 is a distribution supply gutter. A large number of feed protrusions 30 are formed on the bottom surface of the distribution supply gutter 29 . The sorting plate 31 has a structure in which multiple stages are stacked, and the distribution supply gutter 29 distributes and supplies the sorting plate 31 to each stage. The sorting plate 31, like the guide rolls 2, 3, supports 15, 16, rotating shaft 24, etc., can swing back and forth on a swinging support 33 supported by +1132 provided in the front and back direction. Tori (= J is being kicked. 3

A brown rice flow gutter 38 that swings back and forth together with the sorting plate 31 is provided outside the brown rice takeout 1I35, and the brown rice flow gutter 38 is connected to an elevator 39. The brown rice flow gutter 38 is formed long in the front-rear direction. 40 is a storage tank.

As shown in FIGS. 9 and 10, the sorting plate 31 has a structure in which brown rice and unhulled rice a can be separated and taken out, but mixed rice cannot be taken out. That is, the protrusion has a rectangular shape, and the sorting protrusion 34 is provided on the front side, which is larger in area as a whole, so as to be inclined in the direction of the brown rice outlet 35.
The sorting protrusion 34 on the rear side, which is small in area as a whole, is provided so as to be inclined in the direction of unhulled rice removal [J36]. The sorting protrusion 34 is formed with a low slope at the rear and a high slope at the front. A mangoku 42 is provided in a paddy rice takeout gutter 44 provided outside the paddy rice takeout port 36, and a brown rice takeout p3
An immature grain sorting net (or hole) 43 is formed in the brown rice take-out gutter 38 provided outside of the brown rice removal trough 5 .

Next, we will discuss the effect.

When the raw material, unhulled rice a, is supplied to the paddy rice loading machine 1, it is raised by a packet hold 4 through the unhulled rice loading elevator 1, and stored in the fixed hopper 8 through the υ1 output 1''7. When the stored amount exceeds, it flows out from the Ohnohe flow hole 11 and is returned to the filling port 5. By opening the on-off valve 12, the grain stored in the fixed hopper 8 is fed out by the feeding roll 17, and flows on the inclined sink plate 18 to the huller which is diagonally above and below the lower end of the sink plate 18. Roll 13.1
4, the rice is hulled and then flows into the swinging type diffusion device 22. The rotating shaft 24 of the suction floor 23 is rotated, and the eccentric wheel 25 is fitted to the rotating yoke 124. Therefore, when the rotating shaft 24 rotates, the eccentric wheel 25 rotates, and the eccentric wheel 25 rotates. The upper end is fixed to the mouth, do 26
vibrates diagonally up and down, and therefore, the rocking diffuser 22 fixed to the lower end of the iron 26 vibrates diagonally up and down. During this time, the leaf spring 27 elastically supports the swinging diffuser 22.

Therefore, when the hulled material in the swinging type spreading device 22 flows out from the lower end opening 28, it falls in a state where it is uniformly spread in the width direction and is supplied into the distribution supply gutter 29.

The air sucked in by the blower 19 then passes through the air passage 20 and below the rocking type diffuser 22, passing through the grains of rice grains falling from the corner part 28 and passing through the air. When ascending into the sorting section 21, the light rice husks C are blown away and sorted, and the rice husks C are sucked by the suction blower 23 and removed from the system.

The hulled grains which are spread in the width direction of the open end portion 28 and more uniformly loaded are supplied to the distribution supply gutter 29-1-. The distribution supply gutter 29 is integrally attached to the sorting plate 31,
Since the sorting plate 31 is mounted so as to be horizontally swingable in the left-right direction by a vertical swinging support 33, the distribution supply gutter 29 also moves left and right together with the sorting plate 31, and therefore the feed protrusion 30 on the bottom wall The liquid is sent to the terminal, partitioned by a partition plate provided at the end, and distributed and supplied to the sorting plates 31 of each stage.

Paddy rice a and brown rice supplied to sorting plate 31''2 are sorted to sorting plate 3.
When rice 1 moves to the A side (front side) approximately to the main i1i, since the sorting protrusion 34 is high on the A side and low on the mouth side, both the unhulled rice a and the brown rice su are swung toward the A side. At this time, as a secondary phenomenon, the brown rice grains, which have a heavy specific gravity, sink to the bottom layer, and the unhulled rice a floats to the top. Therefore, the brown rice A comes into contact with the sorting protrusion 34 and moves more toward the side A, and therefore, the unhulled rice A slides on the side of the brown rice A and drifts more toward the mouth side. and,
The brown rice that has sunk to the bottom layer is taken out by the sorting protrusion 34 [
It is sent to Ko 35 and taken to brown rice stream 38.

At this time, unripe grain sorting net 43 is used for brown rice flow 41gU3g.
is provided, the sorting net 43 is formed to be quite long in the front-rear direction, and the sorting f143 swings approximately horizontally, making brown rice the most ideal comparison. Since the rice is subjected to a long horizontal oscillation sorting action, it is sorted to the extent that it does not cause problems as a finished rice. Then, only the finished rice flows into the finished rice elevator 39 from the brown rice flow gutter 38 and is stored in the finished rice storage tank 40. The unhulled rice a is gradually moved to the unhulled rice take-out port 36 by the sorting protrusion 34, large foreign objects are removed by the mankoku 42, and returned to the unhulled rice loading elevator 1 through the unhulled rice return port 37.

In the conventional oscillating grain sorting device of the huller, one side of the rectangular sorting plate is divided into three tubes, one for unhulled rice, one for intermediate rice, and one for brown rice. Therefore, when creating a compact structure that could be used as a commercial product, a very long brown rice channel could not be installed at the brown rice outlet. In addition, the conventional oscillating grain sorting device had a structure in which the grains were sieved by moving diagonally up and down in a short flow path, since the grain sorting device was able to oscillate diagonally up and down. Therefore, it was only possible to sort out immature grains by gas.

However, the present invention separates different types of mixed grains into the left and right sides by horizontal reciprocating motion in the front and back directions, and the brown rice is flowed in the direction parallel to the direction of the reciprocating motion through the brown rice outlet of the oscillating sorting section. Since the flow gutter is integrally installed, and the bottom plate of the flow gutter is equipped with an immature grain sorting net, the brown rice is ideally subjected to horizontal reciprocating motion. This results in a sorting state, and therefore, there is an effect that a rotary sorting device, which was required in the past, is not required.
