[0040] The working principle of the present invention is as follows: first, when the height of the rotary spray assembly 23 needs to be adjusted, the lifting servo motor 14 starts to work, and the output end of the lifting servo motor 14 drives the screw rod 15 to rotate. Since the outer wall of the screw rod 15 is threadedly connected with the limit lifting block 16, the rotation of the screw rod 15 will drive the limit lifting block 16 to move up and down in the limit groove 13 of the fog pile rod body 12. With the movement of the limit lifting block 16, the large gear 17 fixedly installed thereon will also move up and down, thereby driving the entire rotary spray mechanism 18 to adjust its height.

When the equipment is lifted to the specified height, the rotary servo motor 20 starts to work, and the output end of the rotary servo motor 20 drives the pinion 19 to rotate. Since the pinion 19 is meshed with the large gear 17 for transmission, the pinion 19 rotates around the large gear 17. The rotation of the large gear 17 drives the entire rotary spray mechanism 18 to rotate in the horizontal direction, realizing all-round spray dust removal. During the rotation of the rotary spray assembly 23, the second limiting block 24 and the second limiting plate 25 connected to the bottom of the rotary spray assembly 23 are used to limit the rotation, thereby ensuring the stability and safety of the rotary spray assembly 23 during the rotation. At the same time, the spray of the rotary spray assembly 23 realizes the dust removal effect on the surrounding environment. The lifting and lowering rotary spray dust removal mechanism 11 is realized through the coordinated work of the lifting servo motor 14 and the rotating servo motor 20. The lifting and rotating functions are realized, thereby realizing all-round spray dust removal. At the same time, through the arrangement of the first limit block 21, the first limit plate 22, the second limit block 24 and the second limit plate 25, the stability and safety of the equipment are guaranteed, and the service life of the equipment is extended. By turning on the switch of the rotating motor 30, the output end of the rotating motor 30 drives the connecting pipe 31 to start rotating, and the connecting pipe 31 drives the spray head 32 to start rotating. The spray head 32 ejects water to the far end through the jet hole 33 for dust reduction, and the spray head 32 atomizes the water through the spray hole 34 to reduce dust at the near end.
