First, the first net board 2 is preliminarily fixed by the combination of the hoisting part 13 and the clamping plate part 14. The first clamping plate 15 at the bottom of the clamping plate part 14 is provided with a clamping groove to clamp the first net board 2. When the spraying mechanism works, water is transmitted to the sprayer 62 through the cooperation of the water supply end seat 61 and the water distribution branch pipes 54. The water mist is sprayed out through the spray holes in the sprayer 62. The water mist mixes with the floating coal powder and then drips downward. The first net board 2 blocks the dripping dirt to prevent the dirt from polluting the transmission path.
