SS02 utilizes the cooperation of a driving cone pulley (204) and a transmission cone pulley (305) on the interval feeding assembly (2) to drive a transmission gear (306) to rotate, realizes the synchronous rotation of a particle bearing disc (501) and the interval feeding assembly (2) under the cooperation of the transmission gear (306) and a tooth-shaped structure (502), and utilizes a scraping baffle (601) to flatten particle grains in the particle bearing disc (501);

the SS03 air supply porous structure (109) conveys air to the bottom of the particle bearing disc (501), air-floating blowing is carried out on particles in the particle bearing disc (501) through an air flow hole (505) on the particle bearing disc (501), dust or fragments in the grains are removed while the grains are adsorbed on the bottom of the particle adsorption disc (102) under the action of negative pressure in the particle adsorption disc (102), and stones are reserved in the particle adsorption disc (102);

SS04 scrapes the grain particles adsorbed on the bottom of the grain adsorption tray (102) into the aggregate chamber through the discharge assembly (4) to be collected.
