DISCLOSURE OF INVENTION Problems to be Solved by the Invention Straw dust and grains with branch branches contained in the grains supplied from the grain supply hopper through the chute-shaped guide portion in the inclined posture are the inlets of the grain guide body. When it is caught on the partition plate for forming the grain guide passage that forms the, even if the grain guide body is shaken, the grain that is supplied later will cause the straw chips and the grain with branch branches to come off the partition plate. Therefore, there is an inconvenience that the entrance of the grain guide body is blocked and the grains cannot be uniformly supplied to the plurality of sorting plates.

The object of the present invention is to eliminate the above-mentioned drawbacks by a simple structural improvement.

[0005]

[Means for Solving the Problems] A feature of the present invention for achieving the above object is to select a plurality of upper and lower stages for sorting grains supplied by a motion having a moving component along a horizontal direction into paddy and brown rice. While supplying the grains from the grain supply hopper to the plate through the chute-shaped guide portion in the inclined posture, the starting end portion of the upper and lower stages of the sorting plate, the grain from the chute-shaped guide portion A grain supply structure of a brown rice sorting device provided so as to integrally move a grain guide body having a plurality of grain guide passages for dividing and guiding to upper and lower sorting plates, in the chute-shaped guide portion. In addition, a partition plate that restricts the supply of grains to the grain guide body is provided near the grain guide body.

[0006]

[Function] Since the flow of the grain supplied from the grain supply hopper through the chute-shaped guide is restricted by the partition plate, a cavity is formed on the back surface of the partition plate. The density of the grain from the partition plate to the entrance of the grain guide body becomes coarse, and the straw chips and the grain with branch stem caught on the partition plate for forming the grain guide passage forming the entrance of the grain guide body Since it can move freely in the cavity as it swings, it can be detached from the partition plate.

[0007]

As a result of the above structure, the partition plate for forming the grain guide passage forming the entrance of the grain guide body has a simple structure in which the partition plate is provided in the chute-shaped guide portion, and grains with straw chips or branch stems are formed on the partition plate. Grain can be prevented from being caught and accumulated, and the grains can be uniformly supplied to the upper and lower sorting plates, and the sorting efficiency in the sorting plate is improved.
