At this time, it is necessary to use a forklift to push the ore to the position of the screw feeder 1.2 or to move the screw feeder 1.2 to a position with more ore by adjusting the position of the frame 1. A material gathering mechanism is fixedly and rotatably connected to the position of the screw feeder 1.2 on the frame 1, which can reduce the number of times the forklift pushes the material or the number of times the position of the frame 1 is adjusted.
