Claims

[Claims for Utility Model Registration] In a clogging prevention device used in a grain sorter that pours granules into a cylinder with a plurality of sorting holes drilled on its side, and sieves the granules by rotating the cylinder. , a support part provided at a position distant from the cylinder, and a pressure that is supported by the support part and presses an outer circumferential surface of the cylinder on the rotationally upstream side from a plane connecting the rotation center axis of the cylinder and the support part. A clogging prevention device for a grain sorter, characterized by comprising:
