[0021] Furthermore, the machine body 1, the rotating roller 2 and the conveying belt 3 constitute an existing belt conveyor. The steering roller 4 is used to change the direction of the conveying belt 3 so that the rotating roller 2 passes through the outer wall of the tensioning roller 5. Bearings are respectively sleeved on both ends of the steering roller 4. The bearings are fixedly connected to the inner wall of the machine body 1, thereby ensuring that the steering roller 4 can passively rotate when the conveying belt 3 moves.
