Description

Technical Field

When the rice is stoned, the rice can be conveyed to the receiving pipe 4 through the conveying mechanism, and the rice entering the receiving pipe 4 is passed through the material distribution box 3 and enters the fish scale plate in the screening box 1. At the same time, the external negative pressure fan generates suction to the screening box 1 through the air duct 2. Subsequently, the rice and impurities are vibrated and screened together. Due to the difference in weight and shape of the rice and impurities, their movement speeds and directions on the vibrating screen are different, thereby achieving further separation, so that the rice is discharged from the discharging tray 5, and the screened impurities such as stones are discharged from the stone discharge tray 6;
