Novel simple sorting device

The utility model discloses a novel simple sorting device, and relates to the technical field of gravel sorting, the novel simple sorting device comprises a centrifugal fan and an air regulating valve, the air regulating valve is located above the centrifugal fan, an air return pipeline is fixedly installed on the air regulating valve, an air inlet pipeline is fixedly installed on the centrifugal fan, and the air inlet pipeline is fixedly installed on the centrifugal fan. The other end of the air inlet pipeline is fixedly connected with a cyclone separator, materials distributed by the distributing device enter the device from the feeding port, when the materials fall to an opening of the air inlet pipeline, the materials are driven by high-speed air from the centrifugal fan to move towards the left side of the sorting box body, and the bottom of the sorting box body is divided into a plurality of independent hoppers by steel plates. The materials moving along with the wind respectively fall into different ho
