Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a rice hulling device.

(Prior art) Japanese Patent Publication No. 52-16941 discloses a system in which a swinging section is provided above a suction fan provided on the side of a wind selection section, and sorting plates are stacked in multiple stages on the top of the swinging section. The sorting plate has a rear side as a supply side and a front side as a discharge side, and the plate surface is rough and tilts to the left and right, and the discharge side is lower than the supply side, and is formed such that its inclination can be adjusted freely, and a paddy rice outlet is formed on the right side of the discharge side, a mixed rice outlet is formed in the middle, and a brown rice outlet is formed on the left side, and a wind sorter and a huller head are formed on the left side of the wind sorter. The supply hopper of the huller head is located lower than the sorting plate, so that the unhulled rice that has fallen into the supply hopper from the unhulled rice outlet is returned to the unhulled rice by a transfer device, and a circulation lifting cylinder is installed behind the wind sorting section. It describes the rice hulling equipment installed.

(Problem B to be solved by the invention) In the above-mentioned known example, since the wind selection part is formed at the lower part of the huller head, the position of the huller head does not become lower than that.
Since the head of the huller is located high, its supply bar is high. Since the supply hopper is high, the swinging grain sorting section is also necessarily high. In addition, since the oscillating grain sorting section oscillates in a tilted manner, there are many vertical and horizontal vibrations.8 The present invention solves all of the above problems.

(Means for solving the problem) Therefore, the present invention provides a swinging section 2 at the upper part of the wind selection section 1,
A grain sorting section 3 in which sorting plates 4 are stacked in multiple stages is provided on the upper part of the swinging section 2, and the sorting plates 4 have a supply side 5 at the rear and a discharge side 6 at the front.
The plate surface is formed with an inclined protrusion 7 which is higher on the left side so that it can horizontally swing to the left and right, and the discharge side 6 is formed lower than the supply side 5 so that the left and right sides can freely adjust the inclination. A paddy rice outlet 14 is formed on the right side, a mixed rice outlet 15 is formed in the middle, and a brown rice outlet 16 is formed on the left side.
8, and the supply hopper 17 of the huller head 18 is located at a lower position than the sorting plate 4. At 7, the unhulled rice 11 that has fallen under its own weight from the unhulled rice outlet 14 is returned, and the hulling rolls n and 28 of the hulling head 18 are inclined rolls so that the hulled rice is rubbed toward the inside of the wind selection section l on the side. The rice huller is constructed as a hulling device in which a circulating grain husk is provided behind the wind sorting section l.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. 1 is a wind sorting section, 2 is a swinging section provided on the upper part of the wind sorting section l, and 3 is a grain selection rocked by the swinging section 2. The grain sorting section 3, which swings substantially horizontally in the left and right direction, is formed by stacking several sorting plates 4 in a multi-tiered manner. The plate surface is formed with an inclined protrusion 7 that is high on the left side and low on the right side.

The grain sorting section 3 differs from the conventional one in that it swings horizontally and horizontally. Conventional products were sorted by tilting and shaking at an angle of approximately 100 to 100 degrees, but tilting causes vertical and horizontal vibrations to occur at the same time.
Unless the support structure at the bottom is constructed to be strong throughout the culm, it will not be able to withstand vibrations.

The grain sorting section 3 of the present invention performs sorting by horizontally moving the sorting plate 4, so there is only horizontal vibration and no vertical vibration.Therefore, even if the grain sorting section 3 is located at the top, The whole thing doesn't vibrate much.

The sorting plate 4 is arranged so that the material supplied to the supply side 5 gradually moves to the discharge side 6 due to vibration, but in order to facilitate the movement from the supply side 5 to the discharge side 6, is formed low.

Since the aforementioned inclined protrusions 7 are formed on the plate surface of the sorting plate 4, all the grains on the sorting plate 4 are influenced by the inclined protrusions 7 and are moved toward the left wall 8, and are moved toward the right wall 9. The board surface is exposed. This point can be easily solved by providing a height difference between the left wall 8 and the right wall 9. That is, an arbitrary adjusting mechanism is attached to the left wall 8 to make the left wall 8 higher. As a result, the grains on the sorting plate 4 are less likely to be shaken by the inclined protrusions 7, and are finally evenly distributed on the plate surface. And, as a natural phenomenon, brown rice 10, which has a heavy specific gravity, is 8 on the left wall.
Paddy rice 11, which is distributed closer to the side and has a lighter specific gravity, is distributed by the right wall 9 side, and brown rice 10 and paddy rice 11 are distributed as a mixture in the middle.

Therefore, the discharge side 6 is partitioned by a partition plate 13 to form an unhulled rice outlet 14, a mixed rice outlet 15, and a brown rice outlet 16.

The grain selection section 3 has a supply side 5 on the rear side and a discharge side 6 on the front side, and the inclined protrusion 7 formed on the plate surface is higher on the left wall 8 and lower on the right wall 9. .

This is an important requirement for the configuration of the present invention.

As described above, with the above structure, the unhulled rice 11 is discharged from the right wall 9 side, so that the operation of returning the unhulled rice 11 taken out from the unhulled rice outlet 14 to the supply hopper 17 becomes much easier.

A huller head is formed on the right side of the wind sorting section 1. The hulling head 18 is formed of a supply hopper 17 and a hulling roll chamber 19, and a part of the supply hopper 17 faces a position near the bottom of the unhulled rice outlet 14, and the whole is provided at a low position. Inside the supply hopper 17, there is a partition plate 2 in the front and rear direction.
1 is provided, and an input port η and a return port n are formed by a partition plate 21.

The unhulled rice 11 that has fallen from the unhulled rice outlet 14 is transferred to the sink plate 24.
, and falls under its own weight from the sink plate 24 to the return port B. A valve is attached to the supply port δ, and the valve opens and closes the input port η. 27. The hulling roll is a hulling roll, and the hulling roll n is pivoted at a higher position than the hulling roll and is provided in the shape of an inclined roll. The hulled grains removed by the hulling rolls n and 28 move laterally toward the winnowing section 1.

The vessel is a sliding channel.

One of the features of the present invention is that the sliding channel device is not vertical as in the conventional case, but is inclined substantially horizontally, so that the position of the huller head 18 can be made very low. When the sliding channel 3 is vertical, the internal structure of the wind sorting section 1, which will be described later, is provided below the huller head, so the height of the huller head 18 is increased. Furthermore, when the wind selection section 1 is provided below the old huller head, the wind selection effect becomes poor because the wind selection section 1 cannot be made too large.

However, in the present invention, since the sliding flow path 6 is oriented horizontally, wind selection can be carried out in the wind selection section l located right sideways to the huller removal head 18, so the wind selection section 1 can be made relatively large and the wind selection section 1 can be made relatively large. You can choose.

A suction tube (9) is provided in the wind selection section 1, and the suction tube (9)
and the sliding flow path 3 are connected. A suction port 31 is provided in the center of the suction cylinder (9), and a wind cylinder is provided on the side of the suction cylinder (9)! Install the windmill blade inside. 34 is a wind exhaust pipe of the wind body. A grain-lifting barrel for frying the mixed rice collected by the grain-collecting conveyor chanting below between the sliding channel device and the suction tube I is provided at the rear of the wind sorting section 1. The upper end of the grain lifting cylinder I rises behind the grain sorting section 3, and its discharge gutter q is provided with a distribution device blade that reaches the sorting plate 4 of each stage.

Below the mixed rice take-out port 15, a guide leading to the grain collection chamber is provided to guide the mixture of brown rice 10 and unhulled rice 11 to the grain collection room. 41 is a finished rice take-out tube.

(effect) Next, we will discuss the effect.

When the unhulled rice 11 is supplied to the input port n, it passes through the supply port n...
The grain is rubbed out by the huller roll n, 28, and falls from the sliding passage device into the grain collection chamber. The light rice husks C are sucked into the suction tube (9), and then passed through the suction port 31! It flows into the interior of the aircraft and is emitted outside the aircraft through the exhaust pipe.

The unpolished rice 10 and the unhulled rice 11 are fed into a rice-lifting straw by a grain collection conveyor 5, and then passed through a distribution device (through a discharge gutter g) to a sorting plate 4 at each stage.
is supplied to the supply side 5 of.

Since the sorting plate 4 is swung in the left-right direction by the oscillating portion 2, the brown rice 10 is placed at the brown rice outlet 16, and the unhulled rice 11 is placed at the unhulled rice outlet 1.
The separated brown rice 10 is taken out from the finished rice take-out cylinder 41, and is separated into unhulled rice take-out port 1.
The unhulled rice 11 separated into 4 parts is returned to the return port B through the sink plate 24 and is hulled. The brown rice 10 and unhulled rice 11 taken out to the mixed rice take-out port 15 are returned to the husk collecting chamber vane and are circulated and sorted.

(Effects) The present invention has a structure in which the swinging part 2 is provided at the upper part of the wind sorting part l, which is different from the structure in which the hulling part is provided in the upper part of the wind sorting part in the known example, and the lower space of the swinging part 2 is wide. Since wind selection can be performed with , complete wind selection can be performed. Further, a grain sorting section 3 in which sorting plates 4 are stacked in multiple stages is provided on the upper part of the swinging section 2, and the sorting plates 4 have a supply side 5 at the rear and a discharge side 6 at the front, and a left side on the plate surface. Since the high inclined protrusion 7 is formed and horizontally oscillates from side to side, grains can be rationally guided and sorted, and since the sorting plate 4 oscillates horizontally, there is little vibration, making it easy to handle. becomes. or,
Since the discharge side 6 is lower than the supply side 5 and the inclination can be adjusted freely on the left and right sides, grains are well filtered. By doing so, uniform distribution can be achieved. A sloped protrusion with a high right side or a simple protrusion will result in low sorting efficiency. Also, there is a paddy rice outlet on the right side of the 6 cases on the discharge side! Mixed rice outlet 1 with 4 in the middle
A brown rice outlet 16 is formed on the left side of 5, and only the huller head 18 is provided on the right side of the wind sorting section l, so separated grains can be taken out to each outlet. Since the supply hopper 17 can be placed extremely low, it is easy to handle. In addition, the supply hopper 17 of the huller head 18 is positioned lower than the sorting plate 4 so that the unhulled rice 11 that has fallen under its own weight from the unhulled rice outlet 14 returns to the supply hopper 17. Since the supply hopper 17 is low, the sorting plate 4 does not rise very high, so the sorting status can be easily checked with the naked eye. In addition, the hulling rolls n and 28 of the hulling head 18 are inclined rolls so that the hulled material is slid sideways into the wind selection section 1 on the side, so that the hulled material is swept through the wind at a considerable speed. It can be supplied into the sorting section 1 and is well sorted. Then, the huller head 18 can be made lower and lower. In addition, since the circulating grain cylinder I was provided behind the wind sorting section 1,
Compared to conventional ones, it can be made much smaller and cheaper, and when the cost is the same, the content can be much more enriched.

In short, the present invention makes it possible to reduce the high price and downsize, which had been a problem in the past, by skillfully utilizing inclined rolls and skillfully combining a horizontally oscillating sorter. be.
