Conveyor belt with automatic screening function based on electromagnetic principle

The utility model provides a conveyor belt with the automatic screening function based on the electromagnetic principle, and belongs to the field of material sorting and conveyance. The conveyor belt is provided with a screening plate, the front end of the screening plate is put over a third sub chain of a front chain from front to back, the rear end of the screening plate is coupled to a first sub chain of a rear chain from front to back and rotates with the first sub chain of the rear chain from front to back as the axis, a permanent magnet is arranged at the bottom of the front end of the screening plate, a repulsion electromagnet and an attraction electromagnet are vertically arranged in the plane where a driving front gear and a driven front gear are located, and the attraction electromagnet and the permanent magnet have opposite polarities. Due to the design structure, conveyance and screening are integrally designed and synchronously achieved, streamline optimization for material screening is achieved, and materials can be directly screened according to the quality of the materials without external equipment.
