The front end face top of the upper bellows 2 is provided with a fan interface 6 for communicating a fan, and the fan pumps airflow outwards from the position, so that dust emission of rice can be avoided, and the rice is caused to fall.
The front end face bottom of the upper air box 2 is provided with a paddy material opening 7 which inclines downwards, and the rear end face bottom of the upper air box 2 is provided with a secondary impurity discharging material opening 15.
