Suction type specific gravity stoner

The utility model discloses a suction type specific gravity stoner, relates to the technical field of grain processing, and provides the following scheme aiming at the problems that when an existing specific gravity stoner is used, a stoner working face is usually fixedly arranged, so that the flow speed of raw materials is adjusted only by changing the wind power, and the stoner effect is poor. A bearing box is fixedly installed at the top end of the supporting plate, a supporting assembly is installed between the supporting plate and the stone removing box, a material collecting box is installed at the top end of the supporting plate, an inclined groove is formed in the inner wall of the bottom of the material collecting box, an air draft device is installed between the supporting plate and the stone removing box, and a feeding mechanism is installed at the top end of the stone removing box. The specific gravity stoner is novel in structure, solves the problems that when an existing specific gravity stoner
