[0031] The utility model provides the following technical scheme:

[0038] As Figures 1-6As shown, when the coal mining machine is working on the thin coal seam, the water tank 8 will seal the water in the water tank 8 to the two atomizing nozzles 6 through the two delivery pipes 7 for atomizing spraying, that is, the water vapor atomized and sprayed by the two atomizing nozzles 6 can atomize and spray the dust and impurities generated by the two crushing rollers 4, thereby improving the cleanliness of the coal mining environment and better practicality.

[0039] When the water capacity in the water tank 8 decreases, the floating plate 15 will move downward with the water capacity, and at this time the two floating plates 15 will move downward on the outside of the two mounting rods 14, and the two mounting rods 14 will slide and limit the floating plate 15, and at this time the extrusion block 16 at the bottom of the two floating plates 15 will extrude and collide with the two gravity sensors 17, and then the two gravity sensors 17 will be transmitted to the controller outside through the central processing module and remind the staff to add water in time, which is more practical and does not need to be observed regularly.
