When the ship unloader unloads materials, the materials are transported from the hopper to the downstream through the vibrating feeder. In the process of passing through the downstream inclined chute, affected by the inclination angle and structure of the chute, the materials are very likely to stick and block when passing through the chute, and are difficult to clean, resulting in long production stoppages and greatly reducing the efficiency of a single machine. This is an extremely important factor restricting production. However, there is currently no device on the market that can be installed inside the chute to clean materials. It is necessary to invent a device that can remove materials in the inclined chute to avoid the problems of slow material discharge and blockage caused by accumulated materials. In view of this, the present application proposes a new type of rotary cleaning device. Utility Model Content
