Specifically, the output shaft of the first motor 9 is arranged vertically downward and connected to the first bevel gear 16. One end of the bidirectional threaded rod 10 is provided with a second bevel gear 17. The first bevel gear 16 and the second bevel gear 17 are meshed. The first motor 9 can be installed on the rotating plate 7.

[0033] Preferably, the outer surface of the first motor 9 is coated with a ceramic waterproof coating.

[0034] like Figure 1 to Figure 3 As shown, the support frame 5 of this embodiment is in a U-shaped structure. The U-shaped support frame is convenient for effectively and stably supporting the dust removal mist cannon tube.

[0035] like Figure 2 and Figure 4As shown, the rotation adjustment mechanism of this embodiment includes a second motor 18, a worm wheel 19, a worm 20 and a rotating rod 21.
