Preferably, a plurality of said spray heads 20 are evenly distributed on said water spray pipe 10, that is, the distances between any adjacent two spray heads 20 along the extension direction of said water spray pipe 10 are equal, thereby providing the production roadway 80 provides a uniform water mist. More preferably, the spraying direction of the spray head 20 is set along the direction of the counterwind flow in the production roadway 80 . Since the dust generated in the production tunnel 80 will diffuse in the production tunnel 80 driven by the wind flow, the spraying direction of the spray nozzle 20 will be set along the counterwind flow, so that the sprayed water mist and the dust will encounter each other. , Play a good spray dust effect.

The hydraulic gun 30 is fixedly arranged above the conveying belt 81 in the production roadway 80 , and the hydraulic gun 30 is used to inject water into the water spray pipe 10 and control the start and stop of water injection. The hydraulic gun 30 includes a water inlet 31 and a water outlet 32, the water inlet 31 communicates with the external water source 70, the water outlet 32 communicates with the water spray pipe 10, and a plurality of the water spray pipes are set for the above-mentioned In the case of 10, a plurality of the water spray pipes 10 are all in communication with the water outlet 32. The external water source 70 can enter the hydraulic gun 30 through the water inlet 31 , and the water entering the hydraulic gun 30 can enter the water spray pipe 10 through the water outlet 32 . Wherein, the external water source 70 can preferably be realized through a water supply pipe in the production roadway 80 .

The hydraulic gun 30 is also provided with a trigger 33 for opening the hydraulic gun 30 , and the opening direction of the trigger 33 is set along the running direction of the transport belt 81 . When the trigger 33 is in a normal state (that is, a state that is not pulled), the hydraulic gun 30 is in a closed state, and the external water source 70 cannot enter the water spray pipe 10 through the hydraulic gun 30 . The nozzle 20 does not spray; when there is an external force to pull the trigger 33 along the running direction of the transport belt 81 (that is, the starting direction of the trigger 33), the hydraulic gun 30 is in an open state. The external water source 70 can enter the water spray pipe 10 through the hydraulic gun 30 to make the spray head 20 spray water mist outward. Preferably, the hydraulic gun 30 can provide power for water flow, that is, it can drive the external water source 70 into the hydraulic gun 30 through the water inlet 31, and drive the water entering the hydraulic gun 30 through the The water outlet 32 enters the water spray pipe 10 .

The switch paddle 40 is used to drive the trigger 33 when the transport belt 81 transports materials, so that the hydraulic gun 30 is in an open state, and the external water source 70 enters the spray gun through the hydraulic gun 30 .
