[0032] The working principle of the coal transportation device is as follows:

[0033] The blanking process: the transport vehicle 5 is driven into the two support tables 8, and the other transport vehicle 5 is located below the blanking port 2. First, the air extractor 42 is opened, and then the blanking port 2 is opened. The coal mine falls into the transport vehicle 5 through the blanking port 2. The dust blocking column 31 blocks the coal dust generated during the loading of the coal. The dust suction port 32 sucks in the coal dust. The coal dust passes through the air extraction pipeline 33 and enters the filter box 34. The large-particle coal dust will hit the large-particle filter plate 35 and then fall into the coal dust collection bin 4. The small-particle coal dust will flow into the right side of the filter box 34 from the gap at the bottom of the large-particle filter plate 35 and then be adsorbed on the cloth bag 36. When the amount of coal dust adsorbed on the cloth bag 36 reaches a certain amount, the air pressure in the filter box 34 will decrease. When the pressure gauge pointer reaches the critical value, the second motor 38 will start to rotate, driving the connecting rod and the beating plate 37 to beat the cloth bag 36, so that the coal dust attached to the cloth bag 36 is beaten off and falls into the coal dust collection bin 4. When the transport vehicle 5 is loaded with coal, the blanking port 2 is closed first, and then the air extractor 42 is closed.

[0034] The transport process: after the transport vehicle 5 is loaded with coal, the third motor 54 is opened. The second motor 38 drives the reel 53 to rotate. The guide soft body 56 moves along the guide rail 55 to the tail of the transport vehicle 5 with the rotation of the reel 53. The dustproof cloth 57 is unfolded and covers the transport vehicle 5 with the movement of the guide soft body 56, preventing the coal from scattering and the dust from flying. The transport vehicle 5 is connected with the traction device through the traction column 51. When the transport vehicle 5 drives out of the support table 8, it will pass through the dust removal roller 7. The soft long hair 71 on the outer surface of the dust removal roller 7 can clean the coal dust in front of the transport vehicle 5. The hard short hair 72 on the outer surface of the dust removal roller 7 can clean the coal dust on both sides of the transport vehicle 5.

[0035] The above is only an embodiment of the present application, and does not limit the patent range of the present application.
