Belt deviation rectifying device

The utility model provides a belt deviation rectifying device which is characterized in that a reversing frame is rotationally connected with a bracket through a main shaft, connecting plates are arranged at two ends of the reversing frame, and fixing sleeves are arranged on the connecting plates; the side rollers are located on the two sides of the horizontal roller respectively, one ends of the side rollers are inserted into the fixing sleeves, the other ends of the side rollers are rotationally connected with rolling wheels, rolling grooves are fixedly formed in the two ends, away from the main shaft, of the bracket, and the rolling wheels are contained in the rolling grooves and can roll in the length direction of the rolling grooves. When a belt supported on the horizontal roller deviates from the longitudinal center line of the belt conveyor, the reversing frame, the horizontal roller and the side roller are driven to automatically rotate around the main shaft, at the moment, the rolling wheel rotationa
