The gear body 206 on one side of the water tank 103 is fixed to the first bevel gear 208, and the first bevel gear 208 is connected to the second bevel gear 209. The first bevel gear 208 and the second bevel gear 209 are movably connected to the support plate 204 through bearings, and the second bevel gear 209 is fixed to the output shaft of the drive motor 210.

When the coal and other materials to be transported are poured onto one end of the conveyor belt 102, in order to prevent the water tank 103 from blocking the coal and other materials from falling onto the conveyor belt 102, start the two driving motors 210 at the same time, so that the output shaft of the driving motor 210 drives the second bevel gear 209 to rotate, and the first bevel gear 208 is meshed with the second bevel gear 209, so that the first bevel gear 208 rotates with the second bevel gear 209. At this time, the second bevel gear 209 drives the gear body 206 on one side of the water tank 103 to rotate, and the gear body 206 is meshed with the toothed belt 207, so that the two gear bodies 206 rotate at the same time, so that the two limit screws 203 rotate at the same time. , through the threaded connection between the limiting screw 203 and the limiting sleeve 205, the support rod 2 moves up along the limiting screw 203, and then the inner wall spacing of the slide 201 is matched with the diameter of the slider 202, so that the support rod 2 is easy to stably lift the water tank 103, so that the water tank 103 is not easy to block the coal and other materials from falling on the conveyor belt 102, and the water spray head 106 sprays water away from the material, which will reduce the dust suppression effect. Since the water spray head 106 sprays water on the surface of the material, the dust particles adhere to the water droplets, thereby reducing the dust concentration in the air.
