[Detailed description of the invention]

[0001]

[Industrial Application Field] The present invention is intended to quickly separate the sorted grains supplied on a circularly moving sorting plate into a brown rice layer, a mixed rice layer and a paddy rice layer, and the separated brown rice is promptly discharged to a discharge side. The present invention relates to a sorting plate in a grain sorter that has been shifted to improve sorting ability.

[0002]

2. Description of the Related Art Sorted grains transferred from a supply side to a discharge side can be swung laterally on a plate surface of a sorter plate which moves circularly in a state of being inclined from a supply side toward a discharge side. Providing the projections that form the rocking surface in the same direction,
A sorting plate in a grain sorter which is discharged from the discharge side while being separated into a mixed rice layer and a paddy rice layer is known prior to the present application, for example, as described in JP-B-62-11632.

[0003]

By the way, in the conventional sorting plate of this type of grain sorter, the projections provided on the plate surface of the sorting plate are arranged so that the projections tend to flow from the supply side to the discharge side. Because of the purpose of swinging the grain to the side, the swinging surfaces are all provided in the same lateral direction. Therefore, when the sorting operation of the sorted grains is performed using the sorting plate, the brown rice that has been swung to the side is the brown rice that has been newly swung several times in the process of flowing to the discharge side. This may hinder the flow and prevent smooth flow to the discharge side, or cause the phenomenon that the thickness of the brown rice layer is reduced and the sorting ability is significantly reduced. And the phenomenon as described above occurs when the bran or the like generated by the frictional action between the sorting grain and the sorting board adheres to the sorting board surface.
In addition, there is a problem that a large number of corns are generated particularly when sifted grains having a high moisture content are sifted.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to push the sorted kernels supplied on the sorting board to the side to make brown rice. Layer, mixed rice layer and paddy rice layer,
The purpose of the present invention is to provide a sorting plate in a grain sorter in which brown rice separated to the side is promptly transferred to a discharge side to speed up the flow of brown rice and thereby remarkably improve the sorting ability.

[0005]

In order to achieve the above-mentioned object, the sorting plate in the grain sorter of the present invention is provided with a sorting plate which moves circularly in a state inclined from the supply side to the discharge side. On the plate surface, a group of projections forming a pressing surface that pushes the sorted kernels flowing down from the supply side toward the discharge side to the side and separates them into a brown rice layer, a mixed rice layer, and a paddy rice layer, and is pressed toward the side And a projection group having an extruded surface capable of extruding brown rice to the discharge side.

[0006] The sorting plate is constructed by arranging two plates, a plate provided with a group of projections formed with a pushing surface and a plate provided with a group of projections formed with an extruded surface, side by side on the same plane. It was done.

[0007] The width of the plate provided with the projections forming the extruded surface of brown rice is preferably 2 to 2.5 times the width of the supply port.

[0008]

After the sorting plate is moved to the right or left by a suitable rotating device in a circular motion, a sorting grain composed of a mixture of brown rice and paddy rice is supplied from a supply port to the supply side of the sorting plate. Then, brown rice with a high specific gravity sinks to the lower layer, and rice with a lower specific gravity rises to the upper layer. By the way, brown rice settled in the lower layer first comes in contact with the group of projections, and at the same time, the projections are provided with a pressing surface that can be pushed to the side in the direction of discharging the sorted kernels. The rice paddy which has been pushed to the side and floated up in the upper layer does not come into contact with the projections, so that the rice is moved on the brown rice in the direction opposite to the moving direction of the brown rice by the circular motion of the sorting plate, and the brown rice is separated from the rice. Therefore, while the sorted kernels flow down from the supply side toward the discharge side, the brown rice layer is formed by the circular motion action of the sorting plate and the pushing action of the pushing face provided on the projection group,
It is separated into three layers: a mixed rice layer and a paddy rice layer. By the way, on the plate surface of the above-mentioned sorting plate, a group of projections forming an extruded surface capable of extruding brown rice pressed sideways by the above-described operation toward the discharge side is substantially orthogonal to the group of projections forming the pressed surface. Therefore, the brown rice pressed to the side is smoothly pushed out in the discharge direction without being stopped and discharged. Therefore, it is possible to solve the phenomenon that the flow of brown rice is slow as seen in the conventional sorting plate in which the projections forming the swinging surface are arranged in the same direction. Even if the particles adhere, or during the sorting operation of the sorted grains having a high moisture content, the separated brown rice can quickly flow down in the discharge direction, and the sorting ability can be significantly improved.
