(Problems to be Solved by the Invention) In the first known example, since the position of the windmill with respect to the surface of the sorting plate is not specific, even if the sorting plate swings, the strength of the wind blowing up the sorting plate will not be affected. There is almost no effect.
That is, in the first known example, the wind turbine simply moves left and right within the casing, and the position of the air outlet of the casing does not change, so there is almost no effect on the air volume.

The second known example has a structure that does not affect the air volume.

In the third known example, the position of the starting end of the casing is directly below the wind turbine, so there is almost no effect on the air volume.

(Means for solving the problem) The present invention has thus been devised by providing a raised side wall 5 on either the left or right side of the sorting plate 1 and a non-raised side wall 6 on the other side, so that the sorting plate A protrusion 7 is formed on one surface so that the side of the raised side wall 5 is higher, and the shape of the sorting plate 1 when viewed from above is approximately square. The sorting plate 1 is formed to be substantially horizontal or inclined in the left-right direction, and is formed to swing back and forth in the left-right direction, and the sorting plate 1 is formed to be inclined in the front-rear direction so as to flow and discharge grains in the front-rear direction. , side walls 4 standing approximately at right angles are provided on the left and right sides of the sorting plate 1, a windmill 19 is provided at the bottom of the sorting plate 1 to provide wind to the sorting plate 1, and the casing 21 of the windmill 19 is connected to the sorting plate 1.

The windmill 19 has a shape in which it rotates once and is connected to the raised side wall 5 at the terminal end, and the suction port 25 of the windmill 19 is opened on the left and right sides.
When the wind turbine 19 efficiency is closer to the raised side wall 5 side, the efficiency of the wind turbine 19 becomes the minimum, and when it is closer to the non-raised side wall 6 side, the efficiency of the wind turbine 1 is minimized.
9 The gist is a swing-type sorting device for unhulled rice and brown rice that maximizes efficiency.

(Example) To explain an example of the present invention, 1 is a sorting plate. The sorting plate 1 is made of a thin metal plate, synthetic resin, or the like. The sorting plate 1 has a substantially rectangular shape when viewed from above. Preferred embodiments are square or rectangular. The sorting plate 1 has a supply side 2 on its front and rear sides, that is, one side on the grain flow side, and a discharge side 3 on the other side. The discharge side 3 has an open structure since it is a part for taking out the grains, but the supply side 2 is provided with a side wall 4 that projects upward to prevent the grains from spilling out.

A raised side wall 5 is provided on either the left or right side of the sorting plate 1, and a non-raised side wall 6 is provided on the other side. The sorting plate 1 is made of a metal plate with porous surfaces all over,
A protrusion 7 is formed on one side of the sorting plate so that the side of the raised side wall 5 is higher. Countless protrusions 7 are formed by press working. The sorting plate 1 is made of iron plate, aluminum, synthetic resin, or the like.

A supply hopper 8 is provided at an upper position on the supply side 2 of the sorting plate 1. The discharge side 3 of the sorting plate 1 in the flow direction is lower than the supply side 2 and has a flow angle β. This flow angle β is not a strong inclination angle such that the grains naturally fall and are discharged, but is an angle that is such that when the sorting plate 1 reciprocates in the left-right direction, the grains are oscillated and discharged while maintaining a layered structure. .
The flow angle β may be fixed or adjustable. The flow angle β can be adjusted either by tilting the entire underframe or by separating only the sorting plate 1. The latter can be easily carried out by attaching one end to a shaft and attaching a screw to the other end.

Although the sorting plate 1 is formed horizontally in its left and right direction, that is, in the sorting direction, it may be installed at an angle. A frame 9 is provided below the sorting plate 1. Bearings 10 and 11 are provided on the left and right sides of the underframe 9, and support rods 1 are provided on the bearings 10 and 11.
The lower ends of 2 and 13 are each pivotally supported. Further, bearings 14 and 15 are provided on the lower surface of the sorting plate 1, and the upper ends of the support rods 12 and 13 are supported respectively. Since a pair of bearings 10 and 11 are also provided on the front and rear sides, the sorting plate 1 is supported by a total of four support rods 12 and 13.

16 is an eccentric wheel, 17 is a rod, the other end of the rod 17 is pivotally attached to the sorting plate 1 side, and when the eccentric wheel 16 rotates, the sorting plate 1 is moved horizontally in the horizontal direction via the rod 17. Rock back and forth.

At the bottom of the sorting plate 1 is a horizontal rotation axis 1 in the front and back direction.
8 is provided, and a windmill 19 is fixed to the rotating shaft 18. The rotating shaft 18 is mounted on bearings 20, 20 fixed to the underframe 9, and the wind turbine 19 can only rotate freely. A casing 21 surrounding the wind turbine 19 is fixed to the lower surface of the sorting plate 1 and swings together with the sorting plate 1.

The starting end 22 is connected to the raised side wall 5 of the wind turbine 19.
The wind turbine 19 is connected to the suction port 25 of the wind turbine 19 by making one spiral rotation from the top of the wind turbine 19 so as to be closest to the side, and then gradually moving away from the wind turbine 19. is opened on the left and right sides.

23 is the wind barrel. 24 is the casing 21
It is a branched casing that branches from the starting end 22 of and reaches the right side wall 6.

(effect) Next, we will discuss the effect.

The mixed rice is supplied to the upper surface of the sorting plate 1, and the eccentric wheel 16
When the support rods 12 and 13 are rotated, the upper ends of the support rods 12 and 13 swing approximately horizontally from the rightmost position shown in FIG. 3 to the leftmost position shown in FIG. 4.

Therefore, in the state shown in FIG. 3 in which the upper ends of the support rods 12 and 13 are closest to the right, the starting end 22 is at the position right beside the raised side wall 5 of the wind turbine 19 and is the closest, and then The windmill 1 gradually moves away.
The wind turbine 19 rotates once from above 9 and is connected to the raised side wall 5 at the terminal end.
When the starting end 22 approaches the closest position, the co-rotation of the wind blown out from the windmill 19 is close to zero, and the entire amount is blown out, reaching the maximum volume. In FIG. 4, the wind turbine 19 and the starting end 22 are separated from each other at the maximum, co-rotation increases, and the wind volume becomes the weakest.

Therefore, the sorting action is shown in Figures 3 and 4.
Figures 5 and 6 are repeated over and over again, and in Figure 3, brown rice and unhulled rice are in a mixed state because they have just been fed, and when this is moved as shown in Figure 4 by the rotation of the eccentric wheel 16. , returns to Fig. 5 (same as Fig. 3), and the mixed rice is placed on the heaped side wall 5.
It is swayed in the direction of , hits the embankment side wall 5, and swells. As a result, more brown rice with a higher specific gravity moves toward the heaped side wall 5, and unhulled rice with a lower specific gravity slides on the upper surface and flows toward the non-heaved side wall 6.
At this time, since the air volume is at its maximum in FIG. 5, it promotes the movement of the unhulled rice, and when the sorting plate 1 moves as shown in FIG. 6, brown rice and unhulled rice are separated. After the separation is completed, there is almost no need for upward wind, so the wind turbine 19 and the starting end 22 are separated.

(Effects) As mentioned above, conventionally, the front surface of the sorting plate is formed to have an uneven surface over the entire surface, and the shape of the sorting plate when viewed from above is approximately square, so that the wind blows through the sorting plate from the bottom to the top. The sorting plate is formed with a perforated plate, and the left and right sides of the sorting plate are horizontal, and the sorting plate is formed so as to swing back and forth in the front and rear directions. is provided with a side wall that stands up approximately at right angles, and a fixed position windmill is provided at the bottom of the sorting plate to provide wind to the sorting plate.The casing of the windmill is fixed regardless of the reciprocating movement of the sorting plate. The rocking type device for sorting unhulled rice and brown rice by cutting off the lower half and using it as an inlet is published in Japanese Patent Application Laid-Open No. 52-50870.
It is publicly known as described in the publication No. In addition, the top surface of the sorting plate is formed into an uneven surface over the entire surface, the shape of the sorting plate when viewed from above is approximately square, and the sorting plate is formed of a perforated plate so that wind can blow from the bottom to the top. The left and right sides of the sorting plate are formed approximately horizontally, and the sorting plate is formed to be inclined in the front and back direction so as to flow and discharge the grains in the front and rear directions, and is also configured to swing back and forth in the left and right direction. A device in which a side wall is provided standing upright at a substantially right angle is disclosed in Japanese Patent Application Laid-Open No. 117235/1983. In addition, a side wall is provided on either the left or right side of the sorting plate, and a side wall is provided on the other side, and a protrusion is formed on the sorting plate surface so that the discharge side is higher, so that wind blows through the sorting plate from the bottom to the top. The sorting plate is formed with a perforated plate, and the left and right sides of the sorting plate are formed horizontally, and the sorting plate is formed so as to be able to swing back and forth in the front and rear directions. A swing-type sorting device is provided in which a windmill is provided at the bottom of the sorting plate, and the starting end of the casing of the windmill is shaped to reach directly below the center of the windmill. It is described in Japanese Utility Model Application Publication No. 39-36961 and is publicly known.

However, in the first known example, since the position of the windmill with respect to the surface of the sorting plate is not special, even if the sorting plate swings, it has almost no effect on the strength of the wind blowing up the sorting plate. That is, in the first known example, the wind turbine simply moves left and right within the casing, and the position of the air outlet of the casing does not change, so there is almost no effect on the air volume. The second known example has a structure that does not affect the air volume. The third known example is also
Because the starting end of the casing is located directly below the wind turbine,
There is almost no effect on the airflow.

However, in the present invention, a raised side wall 5 is provided on either the left or right side of the sorting plate 1, and a non-raised side wall 6 is provided on the other side, and a protrusion is provided on the sorting plate 1 so that the raised side wall 5 side is higher. 7, the shape of the sorting plate 1 when viewed from above is approximately square, the sorting plate 1 is formed of a perforated plate so that the wind blows from the bottom to the top, and the left and right direction of the sorting plate 1 is approximately horizontal or inclined. The sorting plate 1 is formed to be tilted in the front and back direction so as to flow and discharge the grains in the front and back direction, and the sorting plate 1 is formed so as to reciprocate in the left and right directions. Since the side wall 4 that stands up is provided, the mixed brown rice and unhulled rice are swung toward the heaped side wall 5 due to the shaking, and rise against the heaped side wall 5.
At this time, more of the brown rice with a higher specific gravity moves toward the heaped side wall 5, and the unhulled rice with a lower specific gravity slides on the upper surface and flows toward the non-heaped side wall 6. A windmill 19 is provided at the bottom of the sorting plate 1 to provide wind to the sorting plate 1, and the casing 21 of the windmill 19 is
It reciprocates to the left and right along with the sorting plate 1, and its starting end 22 approaches the wind turbine 19 at a position directly beside the raised side wall 5, and then gradually moves away from the top of the wind turbine 19. The windmill 19 has a shape in which it rotates once in a spiral shape and is connected to the raised side wall 5 at the terminal end, and the suction port 25 of the wind turbine 19 is opened on the left and right sides, so that when it hits the raised side wall 5 and swells. Since the air volume becomes maximum, the movement of the unhulled rice is promoted, and the unfilled rice with a small specific gravity slides on the upper surface and flows toward the non-heaped side wall 6, and when it hits the heaped side wall 5 and swells, the air volume increases. This will encourage the movement of the unhulled rice, and after separation as shown in Figure 6,
Since there is almost no need for upward wind, the wind turbine 19 and the starting end 22 are separated and the wind rotates more often.
The air volume is the weakest, and brown rice and unhulled rice are actively separated.
