[0046] In the embodiment: by starting the drive motor 2 at the top end of the support frame 1, the drive motor 2 is driven to rotate the feeding roller 3 connected to the output end of the drive motor 2, and the feeding roller 3 is driven to push the coal blocks to move to the upper surface of the conveyor belt 4, and the coal blocks are conveyed to the uppermost position by the upper end of the conveyor belt 4.
