Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a swing type grain sorting device that separates a mixed rice of unhulled rice and brown rice into unhulled rice and brown rice.

As is well known, as a separating and sorting device for mixed rice, there are a mangoku, which is a simple sieve screen, a swinging type sorting device, and a graig set with a rotating barrel.

All of the separation and sorting devices have the characteristic that mixed rice is separated, and the mixed rice must be returned to the rice separation section by some method.

That is, the mixed rice supplied to the mixed rice separation and sorting device is divided into three types by the sorting device: (1) ... Paddy rice (2) ... Brown rice (3) ... Mixed rice of paddy rice and brown rice The unhulled rice is returned to the hulling device for re-hulling, the brown rice is taken out as finished rice and is usually polished, and the mixed rice is returned to the supply section of the sorting device for circulation sorting again. It allows it to be acted upon.

Conventionally known mixed rice separation and sorting devices are generally as described above, but at the time this invention was proposed, no one had pointed out that the sorting action itself contained defects.

In other words, when mixed rice is separated, mixed rice is always produced, and the mixed rice is normally returned to the supply section of the sorting device for circulation sorting. The prevailing idea was that it was possible to separate a mixture of brown rice and brown rice into different varieties.

However, the present invention deals with the fact that the conventional mixed rice is returned to the supply section of the sorting device for cyclic sorting as a drawback, and goes beyond conventional wisdom to sort the mixed rice without letting it out of the sorting board. As a result, countless different effects can be expected.

First of all, what kind of structure was the conventional sorting device for mixed rice, and why mixed rice was produced when separating unhulled rice and brown rice?The following is a simple explanation with a diagram. It is as follows.

Figures 1 to 3 show typical known examples that are most widely used at present. 1 is a sorting plate, and the surface of the reverse separation plate 1 is formed with countless protrusions 2, making it a rough surface. It is formed. The grains 3 are placed on the plate surface of the sorting plate 1, and the sorting plate l
When the grains 3 are moved diagonally back and forth up and down as shown by the arrows, the grains 3 are gradually swayed in the direction of A due to the flow friction resistance of the projections 2.

In this case, the movement of the grain 3 in the A direction is directly caused by the protrusion 2 on the plate surface.
If only the grains 3 that are in contact with the grains 3 are moved, and the mixed rice is placed on the sorting plate L in a layered manner, and the sorting plate L is moved back and forth as shown by the arrow, then the grains 3 that are in contact with the grains 3 will move, and if the sorting plate L is moved back and forth as shown by the arrow, then the grains 3 that are in contact with the Only the grains 3 that are in contact move in the direction of arrow A, and the grains 3 that are not in contact with the sorting plate l above them do not move, making it possible to sort them.

The sorting plate 1 is mounted on the underframe 4 as shown in FIG. 5.6 is a diagonal rod, the lower end of the diagonal rod 5.6 is pivoted 7.8 on the underframe 4, and a sorting plate l is attached to the upper end of the diagonal rod 5.6.
is mounted on the shaft at 9.10. 11 is an eccentric wheel, and 12 is a rod. When the eccentric wheel 11 rotates, the sorting plate I is reciprocated in the direction of the arrow through the rod 12. The sorting plate 1 has a rectangular shape with a concave rut.
It is formed higher than 4 and is sloping. In addition, in the lateral direction with respect to the direction connecting the supply side 13 and the discharge side 14, one side is the swinging side 15 and the other side is the swinging side 16, and the swinging side 15 is lower than the swinging side 16 at an α angle. It is sloping. The reason why the sorting plate l is tilted at an angle of α is that the grain 3
When the sorting plate l is horizontal, a blank area A is formed on the swinging side 15 as shown in FIG. However, when tilting the α angle as described above,
Blank area A no longer occurs.

A supply funnel 17 supplies the grains 3 from the corners of the supply side 13 and the shaking side 16. The discharge side 14 is opened over the entire width, and an unhulled rice outlet 1 is provided on the swinging side 15 of the discharge side 14.
8, a brown rice outlet 19 is provided on the second side 16 of the discharge side 14, and a mixed rice outlet 20 is provided in the middle thereof.

In this known example, when the mixed rice is fed onto the sorting plate 1 from the supply funnel 17 and the eccentric wheel 11 is rotated, the sorting plate 1 swings in the direction of the arrow opening and the mixed rice on the 14 sorting plate 1 is rotated. swaying, -
In the next sorting process, brown rice with a heavy specific gravity is allowed to sink to the lower layer and is pushed up to the shaking side 16 as shown in El in Figure 3.
The brown rice is diverted and taken out to the brown rice outlet 19. After the unhulled rice a, which has a light specific gravity, floats on top of the brown rice that has sunk to the lower layer, it drifts down the shaking side 15 as shown in E2 and is taken out to the unhulled rice outlet 18, and in the middle there is mixed rice that is not separated as shown in E3. is distributed and taken out to the mixed rice takeout port 20.

As explained above, in the known example, when the unhulled rice a is taken out to the unhulled rice outlet 18 on the shaking lower side 15, and the brown rice is taken out to the brown rice outlet 19 on the shaking side 16, the mixed rice that is not separated between them is The mixed rice is distributed as shown in E3 and taken out to the mixed rice takeout port 20.

However, conventionally, the fact that mixed rice that is not separated in the middle is distributed and taken out to the mixed rice takeout port 20 has not been treated as a defect.

However, after the mixed rice is taken out, it is necessary to return it to the sorting board and re-sort it again, so a mixed rice returning device is always required.

If we were to create a sorting device that does not discharge mixed rice, it would not only be an extremely simple device since it would not require a device to return the mixed rice, but when incorporated into a hulling device,
The overall configuration can be significantly simplified.

Therefore, the present invention has been devised by providing upstanding walls on the front, rear, left and right sides of a sorting plate having a rectangular downward brittle shape, and the sorting plate is configured to swing horizontally or inclined back and forth in the front and back directions, A brown rice transfer plate is provided on the front side of the plate surface of the plate to move the brown rice to either the left or right side by the reciprocating rocking,
A hulled rice transfer plate is provided on the rear side of the plate surface of the sorting plate to move the unhulled rice to either the left or right side by the reciprocating rocking, and a brown rice outlet is provided on either the left or right side of the sorting plate. an oscillating grain sorting device having a paddy rice take-out port formed on the other side, and a joint portion of the brown rice transfer plate and the paddy rice transfer plate being inclined;
A brown rice outlet is formed on either the left or right side of the sorting plate, and a hulled rice outlet is formed on the other side, and the front and rear widths of the brown rice outlet and the unhulled rice outlet are defined as the brown rice outlet>the unhulled rice outlet. an oscillating grain sorting device, which has a brown rice outlet on either the left or right side of the sorting plate and a hulled rice outlet on the other side; The brown rice outlet is the unhulled rice outlet, and the front and rear widths of the brown rice transfer plate and the unhulled rice transfer plate are as follows:
The oscillating grain sorting device is configured such that the side farther from the brown rice outlet and the unhulled rice outlet is larger than the brown rice outlet and the unhulled rice outlet.

The oscillating grain sorting device of the present invention will be explained with the help of a diagram.
In FIG. 4 and subsequent figures, reference numeral 21 is a sorting plate of the present invention, and the sorting plate 21 of the embodiment has a horizontal width 23 longer than a front-rear width 22, and a rectangular shape when viewed from above. . Sorting board?
A rising wall 24 is formed over the entire width at the front edge of (2), and a rising wall 25 is similarly formed over the entire width at the rear edge of the sorting plate 21. Therefore, on the front plate surface of the sorting plate 21,
A brown rice transfer plate A is formed by providing a group of 26 left inclined protrusions on the entire plate surface, the tip of which is directed towards the left if it is on the left side of the left or right side;
On the rear side of the sorting plate 21, a group of right inclined protrusions 27 facing rightward on the right side of the left and right sides are provided over the entire plate surface to form a paddy rice transfer plate B. As is clear from the cross-sectional view of FIG.
one side is higher and the other side is gradually lower).

A brown rice outlet 28 is formed in the left front part of the sorting plate 21, and the rest is closed off by a left wall 29. A paddy/rice outlet 30 is formed in the right rear portion of the sorting plate 21, and the rest is closed by the right wall 31. In FIGS. 4 to 6, 32 is a supply hopper, and in the case of the embodiment, the right side Provided on the front side of the The sorting plate 21 is attached to a support rod 34.3 which is pivoted to the support stand 33.
It is pivoted to the upper end of 4. 35 is an eccentric wheel, and 36 is a rod, and the angle β between the rod 36 and the support rod 34 is smaller than a right angle.

FIG. 5 is a perspective view of the rod 36, and according to this,
The rod 36 has a shape that becomes wider toward the top.

37 is a screw for adjusting the front and back inclination of the sorting plate 21, into which a piece 38 is screwed, and the upper end of the arm 39 is fixed to the piece 38;
The lower end of the arm 39 is pivotally attached to a post 41 provided on a vertically movable rod 40, and the lower end of the rear support rod 34 is pivotally attached to the vertically movable lever 40.

The front and rear widths of the brown rice outlet 28 are larger than the front and rear widths of the unhulled rice outlet 30. The front and back width of the brown rice transfer plate A is larger on the side farther from the brown rice outlet 28 than the part closer to the brown rice outlet 28, and the front and rear width of the unhulled rice transfer plate B is farther than the unhulled rice outlet 30. Paddy rice extraction port 3 is on the side
Therefore, the boundary line 42 between the brown rice transfer plate A and the unhulled rice transfer plate B (in the figure, the rear end of the brown rice outlet 28 and the front edge of the unhulled rice outlet 30) The connecting line) is slanted. That is, the grains sorted on the sorting board 21 are generally in a ratio of 8 parts of brown rice to 2 parts of paddy.

Next, we will discuss the effect.

In the present invention, with the above configuration, when the eccentric wheel 35 is rotated, the angle β between the rod 36 and the support rod 34 is smaller than the right angle, so the sorting plate 21 moves faster when moving from the front side to the rear side, Move slowly when moving from the back to the front.

Therefore, a mixture of unhulled rice a and brown rice was supplied to Hompar 3.
When supplied to the sorting plate 21 from 2, the unhulled rice a and the brown rice are initially in a completely mixed state as shown in FIG. Paddy rice a, which has sunk to the lower layer and has a light specific gravity, floats to the upper layer of the brown rice group and is separated vertically, and only the brown rice grains that have sunk to the lower layer come into contact with the left inclined protrusion 26 and the right inclined protrusion 27.

In this way, the brown rice in the lower layer that has come into contact with the left inclined protrusion 26 and the right inclined protrusion 27 is caused by the inclined protrusion 26 as a secondary phenomenon.
．． Under the influence of <accumulate.

In this way, when brown rice scum is deposited relatively thickly on the front side of the sorting plate 21 and relatively thinly on the rear side of the sorting plate 21, as a tertiary phenomenon, unhulled rice floats to the surface of the brown rice sluice on the front side of the sorting plate 21. A slides on the brown rice tray and moves to the rear side of the sorting plate 21.

When this operation is repeated, as a quaternary phenomenon, brown rice is deposited thickly on the brown rice transfer plate A in front of the sorting plate 21, and then, due to the action of the left inclined protrusion 26, it is deposited on the rising wall 24 on the front side. Start moving along to the left. At this time, the brown rice bM continues to be subjected to the sorting action as the secondary phenomenon described above even as it moves to the left, so the thickness of the brown rice bM gradually increases, and as a result, as a tertiary phenomenon, some of the brown rice in the upper layer ,
On the other hand, it starts to flow toward the rear half of the sorting plate 21, and when the brown rice sluice reaches the left end of the sorting plate 21, it becomes a complete brown rice sluice, and the brown rice is removed from the brown rice outlet, which has a large front and rear width. 2
It will be taken out on the 8th.

Also, as a sixth-order phenomenon, the unhulled rice a slides on the upper layer of the brown rice rack and is transferred to the right side of the sorting plate 21, and is advanced to the right side of the sorting plate 21 by the action of the right inclined protrusion 27, but as it advances, The purity of the rice gradually increases, and finally it becomes complete unhulled rice and is taken out from the unhulled rice outlet 30, which has a narrow front and rear width. The front and rear width of the brown rice outlet 28 is larger than the front and rear width of the unhulled rice outlet 30, and the front and rear width of the brown rice transfer plate A is larger at the side farther from the brown rice outlet 28 than at the brown rice outlet 28, and The front and back width of the unhulled rice transfer plate B is larger on the side farther from the unhulled rice outlet 30 than the unhulled rice outlet 30, so even if brown rice is thickly accumulated on the unhulled rice transfer plate A, it is smoothly transferred to the left side. The present invention, which allows brown rice to be efficiently taken out from the unloading port 28, has vertical walls on the front, rear, left and right sides of a sorting plate having a rectangular profile, and the sorting plate is configured to swing back and forth horizontally or tilted back and forth. A brown rice transfer plate is provided on the front side of the plate surface of the sorting plate to move the brown rice to either the left or right side by the reciprocating motion, and the reciprocating shaker is provided on the rear side of the plate surface of the sorting plate. A paddy rice transfer plate is provided to move the paddy rice to either the left or right side by motion, a brown rice outlet is formed on either the left or right side of the sorting plate, and a paddy rice outlet is formed on the other side of the sorting plate. At the joint between the board and the paddy/rice transfer board, there is a tilted rocking type grain sorting device, and upstanding walls are provided on each of the front, back, left, and right sides of the sorting plate, which has a rectangular shape. A brown rice transfer plate is provided on the front side of the plate surface of the sorting plate to move the brown rice to either the left or right side by the reciprocating movement, and the plate surface of the sorting plate A paddy rice transfer plate is provided on the rear side to move the paddy rice to either the left or right side by the reciprocating swing, and a brown rice removal port is provided on either the left or right side of the sorting plate, and a paddy rice transfer plate is provided on either the left or right side of the sorting plate. The front and rear widths of the brown rice outlet and the unhulled rice outlet are as follows: Each of them has an upright wall, and the sorting plate is configured to swing back and forth horizontally or tilted back and forth, and on the front side of the plate surface of the sorting plate, the brown rice is sorted on either the left or right side by the back and forth swinging. A brown rice transfer plate is provided on the rear side of the plate surface of the sorting plate to move the unhulled rice to either the left or right side by the reciprocating swing, and A brown rice outlet is formed on one side and an unhulled rice outlet is formed on one of the other sides, and the front and rear widths of the brown rice outlet and the unhulled rice outlet are defined as the brown rice outlet>the unhulled rice outlet, and the brown rice transfer plate and the unhulled rice The front and back width of the transfer plate is
Since the swing-type grain sorting device is configured such that the side farther from the brown rice outlet and the unhulled rice outlet is larger than the brown rice outlet and the unhulled rice outlet, the brown rice bowl is placed on the front upright wall. 24, the purity of the brown rice layer gradually increases as it moves to the left, and the unhulled rice a slides on the upper layer of the brown rice rack before being transferred to the right side of the sorting plate 21, where it is sorted. The purity gradually increases as it advances to the right side of the board 21, and the brown rice and unhulled rice a are smoothly transferred on the brown rice transfer plate A and the unhulled rice transfer plate B, and are transferred to the large front and rear brown rice take-out ports 28 and the front and rear unhulled rice a. There is an effect that each unhulled rice can be efficiently taken out from the small width unloading port 30.
