Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oscillating grain sorting device that mainly separates mixed grains of unhulled rice and brown rice into unhulled rice and brown rice, respectively.

Separating paddy rice and brown rice can be said to be extremely easy;
On the other hand, as is well known, it is extremely difficult to separate and sort unhulled rice and brown rice.The separation and sorting equipment for unhulled rice and brown rice started with the Mangoku, which is a simple sieve screen, and then went through the swinging type grain sorting equipment, and the latest model is the rotating barrel type Gray Goo structure. It becomes.

In any case, mixed grains exist, and the mixed grains are returned to the sorting section and separated by some method.

That is, the mixed grains supplied to the sorting device are separated by the sorting device into (1)...unhulled rice (2)...brown rice (3)...the king of mixed grains of unseparated paddy rice and brown rice. The unhulled rice is then returned to the hulling device for re-hulling, the brown rice is taken out as finished rice and is usually polished, and the mixed grains are returned to the feed section of the sorting device and subjected to the circulation sorting action again. It is.

The conventionally known apparatus for sorting unhulled rice and brown rice is as described above, but at the time this invention was proposed, the defect was that the mixed grains were returned to the supply section of the sorting apparatus and recirculated and sorted as described above. No one pointed that out.

In other words, when separating first rice and brown rice, mixed grains are always produced, and the mixed grains are normally returned to the supply section of the sorting device for circulation sorting. The prevailing idea was that it was possible to separate the mixed grains of unhulled rice and brown rice.

However, the present invention goes beyond the conventional wisdom and is a sorting device that does not allow the mixed grains to escape from the sorting plate, and as a result, countless various effects can be expected. It has become.

The reason why conventional sorting equipment always produces mixed grains when separating unhulled rice and brown rice is as follows.

Figures 1 to 3 show typical known examples that are most widely used at the moment. ■ is a sorting plate, and the surface of the sorting plate 1 is formed with countless protrusions 2, forming a rough surface. has been done. When the grains 3 are placed on the rough surface of the sorting plate L and the sorting plate 1 is moved diagonally back and forth up and down as shown by the arrow, the grains 3 are subjected to flow friction resistance by the two groups of protrusions and are moved in the direction of the arrow A. gradually swayed by.

In this case, the movement of the grain 3 in the A direction is directly caused by the protrusion 2 on the plate surface.
Only the grains 3 that are in contact with are moved. For example, with the grains 3 placed on the sorting plate 1 in five to six layers, the sorting plate l is moved as shown by the arrow. If the grains 3 are moved back and forth in the mouth direction, only the grains 3 that have sunk to the bottom layer and are in direct contact with the plate surface of the sorting plate 1 will move in the direction of arrow A, and the two layers superimposed on top of it, not the bottom layer, will move in the direction of arrow A. Although the upper grains are not moved at all, they can be sorted.

This sorting plate 1 is attached to an underframe 4 as shown in FIG. 5 and 6 are diagonal rods, the lower ends of the diagonal rods 5 and 6 are pivoted 7 and 8 on the underframe 4, and the upper ends of the diagonal rods 5 and 6 are provided with a sorting plate l.
are mounted on shafts 9 and 10. 11 is an eccentric wheel, and l2 is a rod. When the eccentric wheel 1l rotates, the sorting plate 1 is reciprocated in the direction of the arrow through the rod l2. The sorting plate 1 has a rectangular shape with a concave track, and one side is a supply side l3, the other side opposite to the supply side 13 is a discharge side 14, and the supply side l3 is a discharge side l3.
It is formed higher than 4 and is sloping. Further, in the lateral direction with respect to the direction connecting the supply side 13 and the discharge side l4, one side is the swinging side 15 and the other side is the swinging side l6, 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 1 is tilted at an angle of α is that the grain 3
When the sorting plate 1 is horizontal, a blank part A is formed on the swinging side 15 as shown in FIG. 2. However, when tilting the α angle as described above,
Blank area A will no longer occur.

17 is a supply funnel, and the grains 3 are supplied from the corners of the supply side 13 and the shaking side 16. The discharge side l4 is opened over the entire width, and the unhulled rice outlet 1 is provided on the swinging side 15 of the discharge side 14.
8, and a brown rice outlet 1 is provided on the shaking side l6 of the discharge side l4.
9, and a mixed grain outlet 20 is provided in the middle thereof.

In this known example, when the mixed grains are supplied onto the sorting plate l from the supply funnel l7 and the eccentric wheel l1 is rotated, the sorting plate l swings in the direction of the arrow opening, and the mixed grains on the sorting plate l are Shake it.

Therefore, as a primary sorting phenomenon, brown rice b with heavy specific gravity sinks to the lower layer and is stirred up to the shaking side 16, and as a secondary phenomenon, it drifts down the shaking side l6 with a trajectory like El in Fig. It is taken out. Paddy rice a, which has a light specific gravity, floats on top of the brown rice b that has sunk to the lower layer, and then drifts to the shaking side l5 as shown in E2 and is taken out to the paddy rice outlet 18, and in the middle there are mixed grains that are not separated as shown in E3. are distributed and taken out to the mixed grain outlet 20.

As explained above, in the known example, when unhulled rice a is taken out to the unhulled rice outlet 18 on the lower side 15 of shaking, and brown rice b is taken out to the brown rice outlet 19 on the upper shaking side 16, mixed grains that are not separated in the middle are used. are distributed as shown in E3 and taken out to the mixed grain outlet 20.

However, conventionally, the distribution of mixed grains that are not separated in the middle and being taken out to the mixed grain outlet 20 has not been treated as a defect.

However, after the mixed grains are taken out, it is necessary to return them to the sorting plate and re-sort them, so a mixed grain returning device is always required.

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

Therefore, in the present invention, an upright wall is formed on the front edge and the rear edge of the sorting plate, which has a rectangular shape, and no mixed grain outlet is formed. A brown rice outlet is formed at one end and a unhulled rice outlet is formed at either end of the side, and a device for horizontal or inclined reciprocating swinging in the front and back directions is attached to the sorting plate. An oscillating grain sorting device equipped with an angle adjustment device, a sorting plate with a rectangular profile, and vertical walls formed on the front and rear edges of the sorting plate, respectively, and a mixed grain outlet. A brown rice outlet is formed at one end of the left and right sides, and an unhulled rice outlet is formed at the other end of the left and right sides, and a device is attached to the sorting plate for horizontal or inclined reciprocating movement in the front-rear direction. , the sorting plate is equipped with a device for adjusting the tilt angle in the left and right directions; The lower end of the support rod is fixed to the shaft, and the screw rod in the left and right direction is fixed to the rear side of the support for free rotation only, and opposing screw grooves are carved on both left and right sides from the center of the screw rod. A piece is screwed into each groove, a vertically movable rod is provided at a lower position of the screw rod, and the lower end of the arm whose upper end is pivoted to the piece is fixed to the vertically movable lever, and the vertically movable The lower end of the rear support rod is fixed to the rod, a mounting base is fixed to the two ends of the front support rod and the rear support rod, and a shaft attachment part is attached to either the left or right end of the mounting base. A sorting plate is attached through the plate, and the upper end of a vertical adjustment rod screwed to the mounting base is engaged with the other end of the left or right side of the sorting plate, and the front edge and the rear edge of the sorting plate are engaged. It is configured as a swinging type grain sorting device in which an upright wall is formed on the top and a brown rice outlet and an unhulled rice outlet are provided on the left and right sides, respectively.

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 denotes a sorting plate of the present invention, and the sorting plate 2l of the embodiment has a front and back width of 2 as shown in FIG.
The left and right @ 23 are longer than 2, and the rut shape is a rectangular shape that is long on the left and right sides. A standing earth wall 24 is formed over the entire width at the front edge of the sorting plate 2l, and a rising wall 25 is similarly formed over the entire width at the rear edge of the sorting plate 2l. Therefore, on the front half of the sorting plate 2l, a group of left inclined protrusions 26 whose tips point toward the left if it is the left side of the left and right sides is formed on the entire plate surface, and the rear half of the sorting plate 2l On the plate surface, a group of right tilting trunk protrusions 27 facing rightward on the right side of the left and right sides is formed over the entire plate surface. As is clear from the cross-sectional view of FIG. 9, the left inclined projection 26 and the right inclined projection 27 are both formed in a direction to draw the grain toward the standing soil wall 24 at the leading edge.

A brown rice outlet 28 is formed in the left front part of the sorting plate 2l, and the rest is closed by a left wall 29. An unhulled rice outlet 30 is formed in the right rear part of the sorting plate 2l, and 32, which is otherwise closed by the right wall 3l, is a supply hopper, which is provided on the front side of the side where the unhulled rice outlet 30 is provided. The lower end of the front support rod 34 is pivoted 47 to the front side of the support 33. A screw rod 37 is pivotally attached to the rear side of the support base 33 so that it can only rotate freely. screw rod 3
Opposite screw grooves 42 and 42 are respectively carved on both left and right sides from the center, and each of the screw grooves 42 and 42 has a piece 38.
, 38 are screwed together. A moving rod 42 is provided below the screw rod 37 so as to be movable up and down, and a boss 4 is attached to the vertical moving rod 42.
1 and 4l are fitted together freely only in rotation, and arms 39 and 39 are attached between the pieces 38 and 38 and the bosses 4l and 41, respectively. Further, the lower end of the rear support rod 34 is pivotally attached to the vertical movement rod 40, and the mounting base 4 is attached to the upper ends of the front support rod 34 and the rear support rod 34.
5 is mounted on the shaft.

Therefore, the sorting plate 2l is pivotally attached to the upper surface of the left side of the mounting base 45 via the shaft attachment part 43, and the top 4 is attached to the right end of the mounting base 45.
4 is fixed on the axis, and key 1 perpendicular to the piece 44! iljjg rod 4
6 are screwed together, and the upper end of the adjusting screw 46 is engaged with the lower end of the sorting plate 2l.

35 is an eccentric wheel, and 36 is a rod, and the angle 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 it shows that the rod 36 has a wider shape toward the top.

Next, we will discuss the effect.

In the present invention, with the above configuration, when the eccentric wheel 35 is rotated, the angle between the rod 36 and the support rod 34 is smaller than a right angle, so the sorting plate 2l moves faster when moving from the front side to the rear side, and When moving from the side to the front, move slowly.

Therefore, mixed grains of unhulled rice a and brown rice b are fed to the supply hopper 32.
When fed to the sorting plate 2l, the unhulled rice a and the brown rice b are initially in a completely mixed grain state as shown in Fig. 10, but in this state they are subjected to horizontal or inclined rocking in the front and back direction, so as a primary phenomenon. The brown rice b, which has a heavy specific gravity, sinks to the lower layer, and the unhulled rice a, which has a light specific gravity, floats to the upper layer of the brown rice group B, and only the brown rice b, which has sunk to the six sea lions layer, has the left inclined protrusion 26 and the right inclined protrusion 27.
come into contact with.

In this way, the lowest layer of brown rice b that has come into contact with the left inclined protrusion 26 and the right inclined protrusion 27 is influenced by the inclined protrusions 26 and 27, and as a secondary phenomenon, gradually forms the raised wall of the front edge of the sorting plate 2l. It moves in the direction of 24 and is deposited relatively thickly on the front half of the sorting plate 2l. As a result, the rear half of the sorting plate 21 becomes relatively thin. In this way, brown rice B is placed on the sorting board 2l.
When the paddy rice a floats to the surface of the brown rice b on the front half of the sorting plate 21, it is deposited relatively thickly on the front half of the sorting plate 21, and becomes relatively thin on the rear half of the sorting plate 21. and slide to the rear half of the sorting plate 21.

The state of this secondary phenomenon is adjusted by rotating the screw rod 37. That is, when the screw rod 37 is rotated, the opposite screw groove 42
．． The pieces 38.38, which are respectively connected to 42, move toward and away from each other, so that the arms 39.3
9 can be inclined or vertical. Therefore, the vertically movable rod 40 is moved up and down by the arms 39, 39, and the rear support rods 34, 34 are moved up and down, thereby adjusting the front and rear inclination of the sorting plate 2l.

As a tertiary phenomenon, when the above-mentioned operation is repeated, the brown rice b that has accumulated on the front half of the sorting plate 21 is distributed along the standing soil wall 24 on the front side due to the action of the tip of the left inclined protrusion 26. Start moving to the left side. At this time as well, the sorting plate 21
The brown rice b that is in contact with the inclined protrusions 26 and 27 on the plate surface of
While moving to the left, it continues to be subjected to the sorting action described above, so as it moves along the rising wall 24, the layer of brown rice B gradually increases in thickness, and as a result, a part of the upper layer of brown rice B teeth,
On the other hand, when the brown rice b starts to flow towards the rear half of the sorting plate 21 and reaches the left end of the sorting plate 2l, the purity improves further and only the perfect brown rice b is left at the brown rice outlet 28. It is taken out. In this case, brown rice outlet 2 of brown rice b
The movement in the eight directions is mainly carried out by the tip of the left inclined protrusion 26, but since the left inclined protrusion 26 has a much larger area than the right inclined protrusion 27, the brown rice can be transferred reliably. Let's do it.

On the other hand, the unhulled rice a slides on the upper layer of the brown rice b on the slope and is deposited on the rear half of the sorting plate 2l, but on the rear half of the sorting plate 2l, it is affected by the right inclined protrusion 27 as a quaternary phenomenon. It is transferred to the right side of the sorting plate 2l. However, due to the action of the right inclined protrusion 27, it is advanced to the right side of the sorting plate 2l, and since the secondary phenomenon is still being sorted, the purity of the unhulled rice a gradually increases as it advances toward the unhulled rice outlet 30. The tertiary phenomenon, that is, the movement of brown rice b toward the direction of the brown rice outlet 28, and the quaternary phenomenon, that is, the movement of the unhulled rice toward the unhulled rice outlet 30, are as follows. This is done by adjusting the left and right inclinations of the sorting plate 2l.

That is, by rotating the adjusting screw 46, the horizontal inclination of the sorting plate 2l is adjusted, and depending on the degree of inclination, the tertiary phenomenon and the quaternary phenomenon can be finely adjusted.

During this time, the mixed grains are accumulated in the center of the sorting plate 21 and swirl around, and the newly supplied brown rice b and unhulled rice a are only metabolized and never leave the sorting plate 2l.

As already mentioned, the separating and sorting equipment for unhulled rice and brown rice started with the Mangoku machine, then went through the swinging type grain sorting equipment, and the latest model has a rotating barrel type Gray Goo structure, but in any case,
There were mixed grains, and the mixed grains were returned to the sorting section and separated by some method. As described above, at the time this invention was proposed, the mixed grains were returned to the supply section of the sorting device, so a returning device was required even for single grains, and when combined with the hulling device, the entire grain was large.・There were flaws that made it more complicated.

In the present invention, upstanding soil walls 24 and 25 are formed on the front and rear edges of the sorting plate 2l, which has a rectangular profile, and no mixed grain outlet is formed, but only one of the left and right edges is formed. A brown rice outlet 28 is provided at one end, and an unhulled rice outlet 30 is provided at the other end.
The 8#i sorting plate 21 is equipped with a device for horizontally or tilted reciprocating swing in the front-rear direction, and the sorting plate 2l is equipped with a device for adjusting the tilt angle in the left-right direction. The device and the sorting plate 2l whose profile is rectangular
Upright walls 24, 2 are provided on the front and rear edges of the
5, no mixed grain outlet 20 is formed, a brown rice outlet 28 is formed at one end of the left and right sides, and a hulled rice outlet 30 is formed at the other end, and the sorting plate 2l is A device for horizontal or inclined reciprocating swinging in the front-rear direction is attached, and a device for adjusting the inclination angle in the left-right direction is attached to the sorting plate 21.The sorting plate 21 is equipped with a device for adjusting the inclination in the front-rear direction. Oscillating grain sorting device and support stand 3
The lower end of the front support rod 34 is fixed to the front side of the support rod 33.
The screw rod 37 in the left and right direction is fixed to the rear side so that it can rotate freely.
Opposite screw grooves 42 and 4 are provided on both left and right sides from the center of the screw rod 37.
2, respectively, and the pieces 38, 38 are screwed into the screw grooves 42, 42, respectively. A vertically movable rod 40 that can move up and down is provided below the screw rod 37, and the upper end is attached to the piece 38. The lower end of the pivoted arm 39 is pivoted to the upper movable rod 40, the lower end of the rear support rod 34 is pivoted to the vertical movable lever 40,
A mounting base 45 is pivotally fixed to the upper ends of the front support rod 34 and the rear support rod 34, and a sorting plate 2l is attached to either the right or left end of the removal base 45 via the pivot attachment part 43, and the sorting The upper end of a vertical adjustment screw 46 screwed onto the mounting base 45 is engaged with either the left or right end of the plate 2l, and the vertical wall 24, 25, and
Since the structure of the swinging grain sorting device is such that the brown rice outlet 28 and the unhulled rice outlet 30 are provided on the left and right sides, the brown rice b is transferred to the brown rice outlet 28 on the left side by the left inclined protrusion 26 on the front half of the sorting plate 2l. The unhulled rice a can be taken out to the unhulled rice outlet 30 on the right side by the right inclined protrusion 27 on the rear half of the sorting plate 2l, and the mixed grains are rotated by metabolism at the center of the sorting plate 2l and then sent to the sorting plate 2l. The above-mentioned defects of the known examples can be overcome without causing discharge to the outside.

Furthermore, in the present invention, due to the above configuration, when the eccentric wheel 35 is rotated, the sorting plate 2l moves quickly when moving from the front side to the rear side, and moves slowly when moving from the rear side to the front side. The brown rice b in the bottom layer is influenced by the inclined protrusions 26 and 27, and as a secondary phenomenon, it gradually moves toward the rising wall 24 at the front edge of the sorting plate 21, and vice versa. The latter half of 21 is deposited relatively thinly, but in this case, the forward and backward movement of grains is caused by the spiral rod 37.
It can be easily done by rotating.

In addition, as a tertiary phenomenon, the brown rice b that has accumulated thickly on the front half of the sorting plate 21 is cured to the front standing soil wall 24 by the action of the tip of the left inclined protrusion 26 and moves to the left, and as it moves, it gradually The layer of brown rice b increases in thickness, while the unhulled rice a slides on the upper layer of brown rice b on the slope and is deposited on the rear half of the sorting plate 21, and as a quaternary phenomenon, it is affected by the right inclined protrusion 27. However, the above-mentioned tertiary phenomenon, that is, the movement of the brown rice b toward the direction of the brown rice outlet 28, and the quaternary phenomenon, that is, the movement of the unhulled rice toward the unhulled rice outlet 30, is caused by the sorting plate 2.
Subtle adjustments can be made by adjusting the left and right inclinations of l.
