Seed classificator for rice seed processing

The utility model relates to the technical field of seed sorting, and discloses a seed sorting machine for rice seed processing, which comprises a box body, a transmission mechanism is arranged in the box body, a screening mechanism is arranged in the box body, and a feeding hole is formed in the top of the box body. Under cooperation of a first belt, a rotating wheel rotationally installed outside a connecting column rotates, under cooperation of a second belt, a second rotating disc installed with a second belt in a transmission mode rotates, and therefore a transmission column fixedly installed with the second rotating disc is driven to rotate; under the cooperation of a transmission column and a rotating frame, an air plate rotates, and air flow generated by rotation of the air plate blows rice seeds in the box body to stably move forwards under the cooperation of an air outlet pipe and an air outlet head, so that the situation that the rice seeds cannot be uniformly blown is avoided. 本实用新型涉及种子精选技术领域，且公开了
