[Industrial applications]

 The present invention promptly separates the selected grains fed on a circularly moving selection plate into a brown rice layer, a mixed rice layer, and a paddy rice layer, and the separated brown rice is immediately moved to the discharge side to improve the selection ability. The present invention relates to a sorting plate in a grain sorting machine.

[0002]

[Prior Art]

 On the plate surface of the sorting plate that moves circularly in a state of being inclined from the supply side to the discharge side, a wobbling surface is formed on which the sorted grains transferred from the supply side to the discharge side can be swung sideways. The sorting plate in the grain sorting machine, in which the projections are provided in the same direction and the sorted grain is separated into the brown rice layer, the mixed rice layer and the paddy rice layer and is discharged from the discharge side, is the one before the present application. It is publicly known as described in Japanese Patent No. 11632.

[Problems to be solved by the device]

 By the way, in the conventional sorting plate in this type of grain sorting machine, the projections provided on the plate surface of the sorting plate are for the purpose of swaying the sorted grains that are about to flow from the supply side to the discharge side to the side. Therefore, all of the wobbling surfaces are provided in the same lateral direction. Therefore, when the selection work of the selected grains was performed using the above-mentioned selection plate, the brown rice swayed to the side was swayed a number of times during the flow process to the discharge side. Although the flow of rice is obstructed by brown rice and it cannot flow smoothly to the discharge side, it causes a phenomenon that the layer thickness of the brown rice layer is thin and the sorting ability is significantly reduced. And, the phenomenon as described above occurs particularly when the bran or the like generated by the frictional action between the selected grain and the selection plate adheres to the surface of the selection plate or when the selection process of the high moisture selection grain is performed. Had problems.

The present invention has been made in view of the above problems of the conventional technique, and an object of the present invention is to push the sorted grains supplied onto the sorting plate to the side and Layer, mixed rice layer and paddy rice layer, and then the laterally separated brown rice is quickly moved to the discharge side to speed up the flow of brown rice, thereby significantly improving the sorting ability. It is intended to provide a sorting plate in a grain sorting machine.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the sorting plate in the grain sorting machine of the present invention is arranged on the plate surface of the sorting plate which is circularly moved in a state of being inclined toward the discharging side from the feeding side. The crushed grains that flow down toward the discharge side are pushed to the side and separated into a brown rice layer, a mixed rice layer and a paddy rice layer, and a group of protrusions is formed, and the brown rice pushed to the side is pushed to the discharge side. And a group of protrusions formed with an extruded surface.

The selection plate is configured by arranging two plates, a plate provided with a projection group having a pushing surface and a plate provided with a projection group having a pushing surface, adjacent to each other on the same plane. It was done.

Further, the width length of the plate provided with the projection group forming the extruded surface of brown rice is preferably 2 to 2.5 times the width length of the supply port.

[0008]

[Action]

 The sorting plate is circularly moved to the right or left by an appropriate rotating device, and then the sorting grain composed of the mixed grain of brown rice and paddy rice is fed to the feeding side of the sorting plate through the feed port. Then, brown rice, which has a large specific gravity, sinks in the lower layer, and paddy rice, which has a low specific gravity, floats in the upper layer. By the way, the brown rice that has settled in the lower layer first comes into contact with the group of protrusions, and at the same time, the protrusions are provided with a pushing surface that can push laterally with respect to the discharge direction of the selected grain. Since the paddy rice that is pushed to the side by the pushing action and floated in the upper layer does not contact the protrusions, the circular motion of the sorting plate moves the brown rice on the direction opposite to the moving direction of the brown rice, and the brown rice and the paddy rice are separated from each other. To be separated. Therefore, while the sorted grains flow down from the supply side to the discharge side, the three layers of the brown rice layer, the mixed rice layer, and the paddy rice layer are generated due to the circular movement operation of the sorting plate and the pushing action of the pushing surface provided in the projection group. To be separated. By the way, on the plate surface of the above-mentioned sorting plate, the projection group that forms the extrusion surface that can push the brown rice pushed laterally by the above-mentioned operation toward the discharge side is approximately orthogonal to the projection group that forms the pressing surface. Since it is installed like a shape, the brown rice pushed to the side can be smoothly pushed out in the discharge direction and discharged without being stagnant. Therefore, it may be possible to solve the phenomenon that the flow of brown rice slows down, which is seen in a conventional sorting plate in which protrusions having a wobbling surface are arranged in the same direction, can be solved, or bran or the like generated on the surface of the sorting plate. Even if it adheres, or even during the work of selecting high-moisture selected grains, the separated brown rice can be quickly flowed down in the discharge direction, and the sorting ability can be significantly improved.
