By setting an air extractor, a cleaning pipe, and a filter plate, seeds can be filtered in the cleaning pipe. By setting a classification plate and a material guiding plate, the screened seeds can be classified and stored. Qualified seeds enter the cleaning box through the material guiding plate. By setting a motor, an adjusting rod, a baffle, a discharge chute, and a discharge pipe, the discharge amount can be controlled by controlling the rotation of the motor to avoid blocking the discharge port. However, when this seed cleaning device is in use, the seeds inside only undergo one-time cleaning, so that the cleaned seeds still carry some dust and light impurities, and the cleaning effect is relatively poor.
