An empty track 5 is arranged on the outer side of the car dumper room 1; the tipper overturns the carriage 6, and after the coal in the carriage 6 is poured out, the empty carriage 6 is conveyed to the empty track 5.

A trench 7 which is sunken downwards from the ground is arranged on the side of the extension direction of the empty wagon line track 5, and in the embodiment, the trench 7 is arranged between the empty wagon line track 5 and the wagon tipper room 1. The trench 7 extends along the length direction of the empty lane rail 5, in the embodiment, the length of the trench 7 is 70 meters, and the width and the depth are both 70 centimeters; the top end of the trench 7 is flush with the ground. A coal outlet 8 is formed in the bottom of one end, close to the coal grate 4, of the trench 7, and a first coal conveyor 9 is arranged in the trench 7; the first coal conveyor 9 conveys coal along the extending direction of the trench 7 and can convey the coal bottom into the coal outlet 8.

A pipeline 10 is arranged below the coal outlet 8; one end of the pipeline 10 is communicated with the coal outlet 8, and the other end of the pipeline 10 is communicated with the collecting pit 2 above the coal grate 4. A second coal conveyer 11 is arranged in the pipeline 10; the second coal conveyer 11 is conveyed along the extending direction of the pipeline 10, and the second coal conveyer 11 receives the coal bottom falling from the coal outlet 8 and sends the coal bottom to the upper part of the coal grate 4. In this embodiment, a coal dropping hopper 12 is arranged at the lower end of the coal outlet 8, and the coal dropping hopper 12 is located above the second coal conveyor 11; the coal hopper 12 plays a role in gathering and guiding the coal bottom, and can smoothly drop the coal bottom onto the second coal conveyor 11.

In this embodiment, the inner wall of the trench 7 is provided with a concrete layer 13, that is, during construction, a concrete trench is built, so as to avoid the problem that the directly dug soil trench is not stable enough in structure. In order to further improve the strength of the trench 7, a protective layer 14 may be disposed on the inner wall of the concrete layer 13, in this embodiment, the protective layer 14 is an iron sheet layer; in practical applications, the protective layer 14 made of other materials can be used according to requirements.
