the step of removing the coal dust on the belt 18 of the belt conveyor comprises the following steps:

the vibration motor 91 is started through the control panel, the vibration motor 91 drives the knocking rod 92 to rotate, and the knocking rod 92 rotates to enable the knocking block 93 at the end part of the knocking rod 92 to knock the lower surface of the belt 18, so that the coal dust attached to the upper surface of the belt 18 is separated from the belt 18; the coal dust after separation is convenient to clean through a belt flushing system.

The opening and closing motor 15 is started through the control panel, and the opening and closing motor 15 drives the opening and closing rod 11 to move through the first gear set 14, so that the movable door 10 is opened; meanwhile, the opening and closing motor 15 drives the water outlet pipe 52 to rotate through the second gear set 16, the water outlet pipe 52 rotates to enable the nozzle of the spray pipe 54 to penetrate through the window, and the nozzle faces the belt 18 of the belt conveyor 2;

the control board controls the second electromagnetic valve to open and controls the water pump to operate, the water pump pumps out water from a water source, the water is conveyed to the water inlet pipe 51 through the water conveying main pipe 4 and then is sprayed out from the nozzle of the spray pipe 54 through the hose 55 and the water outlet pipe 52, and the sprayed water column can clean coal dust on the belt 18 of the belt conveyor 2.

The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
