Belt conveyor

The utility model provides a belt conveyor. The belt conveyor comprises a rack, wherein the driving device is fixed on the machine frame; a conveyor belt; the conveying belt is arranged on the outer side of the driving device in a sleeving mode, and the driving device drives the conveying belt to move. The conveying belt comprises a plane conveying belt body and a baffle fixed to the plane conveying belt body. A first limiting component is arranged on the edge of the plane conveying belt, and a second limiting component is arranged on the edge of the baffle. The limiting frame is fixed to therack, and a first limiting groove and a second limiting groove are formed in the limiting frame; the first limiting groove is matched with the first limiting component, and the second limiting grooveis matched with the second limiting component. According to the belt conveyor, friction between the edge of the conveying belt and the rack is avoided; and meanwhile, the friction between the limitingpiece and the limiting gro
