[0036] A specific application of this embodiment is:

[0037] When in use, start the water pump 111 to transport water to the spray seat 12 through the hose 113 and the connecting pipe 122, and then spray it out through the nozzle 121 to reduce dust. Then start the electric push rod 134 to drive the fixed rod 314 to move forward or backward through the push block 135, then the fixed rod 314 drives the slider 311 to slide in the arc frame 131 through the connecting block 313, and the slider 311 drives the spray seat 12 to rotate through the connecting rod 312, then the spray seat 12 rotates on the lifting column 142 through the rotating shaft 123. Since the slider 311 and the connecting rod 312 are rotatably connected, the slider 311 can smoothly drive the spray seat 12 to rotate during movement, and the bottom of the slider 311 rotates on the connecting block 313, and the fixed rod 314 slides on the connecting block 313. Therefore, when the push block 135 is pushed and pulled, the slider 311 rotates with the connecting block 313 and the connecting block 313 and the fixed rod 314 slide and cooperate. When the slider 311 is used, the slider 311 can slide smoothly on the arc frame 131.

The motor 146 is started to drive the bevel gear 2 145 to rotate, and the bevel gear 2 145 drives the threaded rod 143 to rotate through the bevel gear 144. Since the bottom of the lifting column 142 is threadedly connected with the threaded rod 143, when the threaded rod 143 rotates, the lifting column 142 will move upward or downward, and the stabilizing frame 147 can limit the lifting column 142, so that the lifting column 142 makes a linear motion. The lifting and lowering of the lifting column 142 drives the spray seat 12 to rise and fall together, and the height is adjusted. When the height increases, the dust reduction range can be increased, thereby controlling the dust reduction range according to different needs, and the practicality is better.
