A feed hopper 13 is fixedly installed at the bottom of the shell 1, so that the material can smoothly fall onto the belt conveyor body 3 for transportation. At the same time, a discharge pipe 14 is fixedly installed at the bottom of the shell 1 for discharging the transported material. In order to adjust the discharge height, an adjustment mechanism is installed on the bottom plate 4. This mechanism adjusts the angle of the shell 1 and then changes the height of the discharge pipe 14 to adapt to different transportation requirements. Finally, in order to solve the problem of material accumulation inside the shell 1, the utility model is equipped with a cleaning mechanism on the shell 1. The main function of this mechanism is to push out the material accumulated inside the shell 1 after the use of the belt conveyor body 3 is over, thereby avoiding material waste.
