[0040] The working principle of an embodiment of the present invention:

[0041] When the present invention works:

[0042] The spiral feeding device 5 is inserted into the bulk material, and the material is pushed up by driving the spiral blade to rotate. Then, the horizontal conveyor 6 at the upper end of the feeding device 5 pushes the bulk material into the arm conveyor 8, and the arm conveyor 8 transports the bulk material into the hopper 11. The hopper 11 is equipped with a generator set 12. The impeller 13 of the generator set 12 and the generator 14 are connected together. In the process of the bulk material falling from the hopper 11, it collides and squeezes the impeller 13, so that the impeller 13 rotates, and the impeller 13 rotates to drive the generator 14 to rotate and generate electricity. A part of the gravitational potential energy of the bulk material is recovered through the generator set 12, and the bulk material enters the shore conveyor 15 through the discharge port below the hopper 11. The shore conveyor 15 transports the bulk material to the yard to complete the entire unloading process. The impeller 13 isolates the bulk material during the rotation process, which effectively prevents the bulk material from blocking the discharge port when it falls from the discharge port.
