[0035] In the above scheme, the material carrier is passed through the loading channel 1, and the mounting structure 2 on the upper side of the loading channel 1 is used to support the discharging equipment. The liftable discharge pipe at the bottom of the discharging equipment is used to discharge the material into the hopper of the material carrier. The telescopic pipe 4 of the liftable discharge pipe can be retracted. During the material discharging process, the distance between the material and the distance meter is monitored in real time through the lower position distance meter and fed back to the controller 10. The lifting mechanism drives the material pipe end ring 5 to rise as the material stacking height increases, so that the material falls at a fixed point within the hopper range, reducing on-site material dust and waste. The horizontal distance meter 6 is used to detect the relative position of the distance meter and the two sides of the hopper. When the height of the horizontal distance meter 6 exceeds the height of the hopper, it is fed back to the controller 10. The controller 10 controls the lifting mechanism to stop rising and controls the buzzer 8 to work to remind the driver to move the material carrier.
