A water inlet pipe 312 is provided on the side of the atomizing nozzle 307, and a movable groove 31 is provided on the side of the mounting sleeve 306. 1. Another movable groove 311 is also provided on the side of the pad 301. The positions of the two movable grooves 311 correspond to each other. The water inlet pipe 312 passes through the two movable grooves 311 and extends to the outside of the pad 301. A connecting pipe 5 is provided between the water inlet pipe 312 and the water outlet pipe 4. A protective net 308 is provided at the water outlet of the atomizing nozzle 307.

[0030] As can be seen from the above, the water supply pipe is connected to the pipe fixing member 123, and one end of the water supply pipe is connected to the water pump, and the other end is connected to the water outlet pipe 4 inside the top mounting base plate 2, and then the water inlet pipe 312 is connected to the water outlet pipe 4 through the connecting pipe 5, so that the atomizing nozzle 307 can receive water, and the water at the water storage place is pumped into the water outlet pipe 4 through the water pump and enters the atomizing nozzle 307 through the connecting pipe 5 and the water inlet pipe 312, so that the atomizing nozzle 307 can spray water mist to reduce dust on the highway construction site. When the angle of the atomizing nozzle 307 needs to be adjusted, the motor 303 is rotated to adjust the angle. Drive the angle adjustment rod 304 to rotate. Since the angle adjustment rod 304 is fixedly connected to the mounting part 305, when the angle adjustment rod 304 rotates, the mounting part 305 will also rotate with the rotation of the angle adjustment rod 304. The rotation of the mounting part 305 will drive the atomizing nozzle 307 to adjust the angle. When the angle of the atomizing nozzle 307 changes, the atomizing nozzle 307 will squeeze the clamping block 309, so that the clamping block 309 squeezes the spring 310, and then under the elastic force of the spring 310, the angle adjustment of the atomizing nozzle 307 is more stable, so that the device can meet the dust reduction work in different ranges.

[0031] Working principle: The driving motor 106 drives the rotating rod 107 to rotate forward, and the rotating rod 107 drives the first threaded rod 108 and the driving gear 120 to rotate. The driving gear 120 rotates to drive the driven gear 122 to rotate. The driven gear 122 rotates to drive the connecting rod 121 and the second threaded rod 111 to rotate. When the first threaded rod 108 rotates, the mounting plate 115 on the surface of the first threaded rod 108 will move on the surface of the first threaded rod 108. At this time, the slider 116 on the side of the mounting plate 115 moves on the surface of the slider 118, so that the mounting plate 115 and the universal wheel 119 at the bottom of the mounting plate 115 move to The first threaded rod 108 and the second threaded rod 111 are in opposite directions of the threads, and the rotation of the second threaded rod 111 drives the threaded block 113 to move upward on the surface of the second threaded rod 111, thereby moving the movable plate 112 and the fixed rod 114 upward, so that the fixed rod 114 is separated from the ground, so that the device can be moved normally by the universal wheel 119. When the device needs to be fixed, the driving motor 106 drives the rotating rod 107 to reverse, and repeats the above steps to move the fixed rod 114 downward and the universal wheel 119 upward, thereby fixing the entire device;

[0032] After the device is fixed, the water delivery pipeline is connected with the pipeline fixing part 123, one end of the water delivery pipeline is connected with the water pump, the other end is connected with the water outlet pipe 4 inside the top installation base plate 2, then the water inlet pipe 312 and the water outlet pipe 4 are connected through the connecting pipe 5, so that the atomizing nozzle 307 can receive water source, the water in the water storage place is pumped into the water outlet pipe 4 through the water pump and enters the atomizing nozzle 307 through the connecting pipe 5 and the water inlet pipe 312, so that the atomizing nozzle 307 can spray water mist to carry out dust reduction work on the highway construction site.

[0033] When the angle adjustment of the atomizing nozzle 307 is needed, the angle adjustment rod 304 is rotated by rotating the motor 303, since the angle adjustment rod 304 is fixedly connected with the mounting part 305, when the angle adjustment rod 304 rotates, the mounting part 305 also rotates with the rotation of the angle adjustment rod 304, the mounting part 305 rotates to drive the angle adjustment of the atomizing nozzle 307, when the angle of the atomizing nozzle 307 changes, the atomizing nozzle 307 extrudes the clamping block 309, the clamping block 309 extrudes the spring 310, and then under the elastic force of the spring 310, the angle adjustment of the atomizing nozzle 307 is more stable.
