[0002] Coal transportation refers to the transportation of qualified coal to its destination, including ports, power plants and boiler rooms, by rail, road, coastal and inland waterway after it is mined. Coal transportation includes rail, water and road, or single mode direct transportation, or rail, road and water multimodal transportation.

[0003] Since a large amount of smoke and dust is easily generated during coal transportation, a corresponding device is required for spray dust reduction. There is an existing automatic spray dust suppressor for mining with a Chinese patent publication number of CN210217815U. It uses a ring coil as a detection module, uses the electromagnetic induction principle to determine whether a train has passed, and controls the spray by controlling the solenoid valve switch to achieve automatic spray dust reduction when the train passes. When the mining locomotive passes through the ring coil, the control module determines that the vehicle has passed, and then issues a command to control the solenoid valve to open, and the water flows into the spray water pipe and is sprayed out through the spray port. After the dust concentration is reduced to the set index, the control module controls the solenoid valve to close to stop the spray. The automatic spray dust suppressor provided by the utility model is safe and reliable, easy to maintain, low cost, and easy to promote industrialization.

[0004] However, the spray area of ​​the device is fixed, which makes it difficult to meet the needs of large-area spray dust reduction and is quite limited. Utility Model Content
