[0027] A fog cannon cylinder 3 is rotatably mounted on the top of the vehicle body 1 via a support assembly. The support assembly includes a base 201 fixedly connected to the top of the vehicle body 1, and a bracket 202 fixedly connected to the top of the base 201. The bracket 202 is U-shaped with its opening facing upwards. An installation shaft 301 is fixedly connected to the outer wall of the fog cannon cylinder 3. The fog cannon cylinder 3 is rotatably connected to the inner wall of the bracket 202 via the installation shaft 301. A stepper motor 302 is bolted to the rear side of the bracket 202. The output end of the stepper motor 302 is connected to one of the installation shafts 301 via a coupling. When the stepper motor 302 is started, it drives the installation shaft 301 to swing the fog cannon cylinder 3 within a certain angle, thereby increasing the range of atomization and dust removal.

[0028] The port of the fog cannon cylinder 3 is equipped with an atomizing dust removal mechanism. The atomizing dust removal mechanism includes an annular pipe 401 fixedly connected to the port of the fog cannon cylinder 3. Several atomizing nozzles 402 are fixedly connected to the annular pipe 401. A water pump 403 is fixedly connected inside the water storage chamber. A water inlet pipe 404 is fixedly connected to the water inlet of the water pump 403. A water outlet pipe 405 is fixedly connected to the water outlet of the water pump 403. The other end of the water outlet pipe 405 is fixedly connected to the annular pipe 401. A fan 406 is fixedly connected inside the fog cannon cylinder 3.

[0029] An auxiliary mechanism is provided at the port of the fog cannon cylinder 3. The auxiliary mechanism includes a mounting plate 501 fixedly connected to the inner wall of the fog cannon cylinder 3. A guide shell 504 is connected to the mounting plate 501 through an elastic component. The outer edge of the guide shell 504 is arc-shaped. The elastic component includes a slide rod 502. The slide rod 502 is slidably connected to the mounting plate 501. The slide rod 502 moves back and forth along the axis of the fog cannon cylinder 3. One end of the slide rod 502 extends out of the fog cannon cylinder 3 and is fixedly connected to several circumferentially arranged mounting strips 503. The end of the mounting strips 503 is fixedly connected to the guide shell 504. The end of the slide rod 502 away from the mounting strips 503 extends out of the mounting plate 501 and is fixedly connected to a limit block 505. A spring 506 is fixedly connected between the limit block 505 and the mounting plate 501. The spring 506 is wrapped around the outer circumference of the slide rod 502.

[0030] The auxiliary mechanism also includes a power assembly, which drives the guide shell 504 to move back and forth along the axis of the fog cannon cylinder 3. The power assembly includes a mounting bracket 507 fixedly connected to the outer wall of the fog cannon cylinder 3. A rotary motor 508 is fixedly connected to the mounting bracket 507. The output end of the rotary motor 508 is connected to a rotary shaft 509 through a coupling. The rotary shaft 509 is rotatably connected between the inner walls of the fog cannon cylinder 3. A cam 510 is fixedly connected to the rotary shaft 509. The cam 510 is located on the side of the limit block 505 away from the slide rod 502. The corner of the limit block 505 near the cam 510 is rounded to improve the stability of the cam 510 when it moves relative to the limit block 505.

[0031] Working principle: During use, water from the storage chamber is pumped by water pump 403 through water outlet pipe 405 to annular pipe 401, and then atomized and sprayed out by atomizing nozzle 402 for dust removal. Simultaneously, stepper motor 302 and rotary motor 508 are activated. Stepper motor 302 drives mounting shaft 301 to swing the fog cannon cylinder 3 within a certain angle. Rotary motor 508 drives rotating shaft 509 to rotate cam 510. When the tip of cam 510 abuts against limit block 505, cam 510 drives limit block 505 to move slide rod 502. 2. The mounting strip 503 drives the guide shell 504 to move away from the port of the fog cannon cylinder 3. After the tip of the cam 510 rotates away, the limit block 505, under the action of the spring 506, drives the slide rod 502 to move the mounting strip 503 and the guide shell 504 towards the port of the fog cannon cylinder 3 to reset. This causes the guide shell 504 to move back and forth towards or away from the port of the fog cannon cylinder 3, guiding the surrounding water mist, expanding the water mist spraying range, and improving the dust removal effect. The fan 406 is then started to blow the water mist away from the fog cannon cylinder 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
