Description

Grain sorting device equipped with a stone grinder {GRAIN SELECTOR HAVING A STONE SEPARATOR}

The present invention relates to a grain sorting device equipped with a stone grinder.

In general, grains such as perilla, sesame, rice, barley, soybean, and red bean contain straw, scallops, male cuttings (stems attached to ears), branched grains (branches and stems), soil, sandy soil, dust, and small stones. It is a state in which a large amount of foreign substances are mixed, and the process of removing the foreign substances and selecting and selecting only the grains is essential before processing the rice.

The selection of grains such as perilla, sesame, rice, barley, soybean, and red bean is done by a grain selector.

The conventional grain selector is composed of a hopper for temporarily storing threshed grain, a wind-generating blade, a round wing box with blades installed, a motor returning the blades, and an outlet through which the selected grains are discharged.

And, when the conventional grain selector attaches the threshed grain to the hopper and operates the motor, foreign substances are blown away from the grain falling from the hopper by the wind caused by the rotation of the blades, and the grain is discharged to the outlet.

However, the conventional grain selector must be equipped with a shaft for fixing the blades and blades of the selected grains, a device for rotating the blades, and the like, and the wing tube must also be enlarged to accommodate these devices.

In addition, since the conventional grain selector needs to add a device for transmitting power from the motor to turn the blades, the device is large and the structure is complicated compared to the simple function of generating only wind.

In addition, foreign substances such as stones having a similar size and shape to the main raw material and different specific gravity may be mixed in the grain, and it was practically impossible to separate foreign substances such as stones similar in size and shape to the grain using a grain selector. .

Therefore, the grains selected through the sorter must be transported to the post-processing place for the work of removing foreign substances such as stones, which are similar in size and shape to the main raw material and having a different specific gravity, or for packing through the stone mill.

In the conventional sorter, since the sorted grains are discharged to the lower part of the hopper, there is a hassle to carry out the operation of transferring to another post-processing place.

In addition, the grains selected through the selector are removed from the grains because a separate stone mill must be used to remove foreign substances such as stones with different specific gravity and size and shape contained in the grains through the stone grinder. There was a problem that the work was inconvenient and took a long time to work.
