However, when the existing belt conveyor is used, because the belt conveyor works in a single-side load-bearing closed loop mode, the same stress deformation is repeated in each cycle period, particularly in the position of a driving roller connected with a machine head and a motor, the conveying belt is bent along with the driving roller when contacting the driving roller and bearing the maximum traction load, and at the moment, the bending stress of the outer surface of the conveying belt is obviously much larger than that of the inner surface, so that the outer surface of the conveying belt breaks through the fatigue life most easily and cracks and then is broken at any time under long-term work, and the production accident that the conveying belt is torn and broken is frequent. In addition, the bearing surface of the conveying belt for bearing the coal materials is the same as the surface of the conveying belt which bears the larger bending stress, and hard or barbed materials carried in the coal materials are easy to wear and even scratch the surface of the conveying belt, namely the conveying belt has the problem of shortened service life caused by wear and scratch.
