The invention has the advantages and positive effects that: 1. can realize the bulk cargo conveying with larger inclination angle. As shown in fig. 2 and 3, the conveyer belt of the conveyer not only wraps the bulk material in the pipe, but also the friction force between the bulk material and the conveyer belt is larger due to the force exerted on the conveyer belt by the press rollers, the conveying inclination angle is further improved to 45 degrees, and the conveyer belt is suitable for the construction of conveying lines under particularly complex environments. 2. The deviation problem of the conveying belt of the general belt conveyor can not be caused, and the twisting problem of the conveying belt of the circular tube conveyor can not be caused. 3. The conveying capacity is larger. As shown in fig. 2, the conveyor conveys bulk material with a larger cross-sectional area than a conventional trough belt conveyor, meaning that the conveying capacity is greater. 4. As shown in fig. 2, when the amount of the bulk material filled in the forward-stroke conveying belt is relatively small, the

spring connecting pieces

161 and 162 pull the left and right forward-stroke pressing

rollers

111 and 112 to press the conveying belt 2 to reduce the cross-sectional area, so as to prevent the bulk material from sliding off.
