A three-way pipe 23 is fixedly connected, and alloy pipes 24 are fixedly connected on both sides of the three-way pipe 23. An inclined square pipe 25 is fixedly connected to one end of the alloy pipe 24 away from the three-way pipe 23. An atomizing nozzle is fixedly connected to the outer wall of the inclined square pipe 25. The polyester fiber filter cartridge 215 is used to filter and protect the atomizing nozzle from clogging. The pump 22 is controlled to work, and the water in the water storage tank 21 filtered by the polyester fiber filter cartridge 215 can be extracted with the help of the extension pipe 214, and then transported to the three-way pipe 23. The water then passes through the alloy pipe 24 and the inclined square pipe 25, and then is sprayed from the atomizing nozzle to the grinding area to achieve the dust reduction function.

[0022] As an implementation method in this embodiment, Figure 2 and Figure 3As shown, a rubber cone plug 211 is movably connected to the right side of the water storage tank 21, a counterweight block 216 is fixedly installed on the bottom of the inner wall of the water storage tank 21, a rubber cone plug 212 is movably connected to the top of the water storage tank 21, and a stainless steel filter cartridge 213 is fixedly connected to the top of the inner wall of the water storage tank 21. Impurities filtered out by the outer wall of the polyester fiber filter cartridge 215 will fall under the influence of gravity, and guided by the counterweight block 216, the impurities can be caused to fall to the middle of the bottom of the inner cavity of the water storage tank 21, and the rubber cone plug 211 can be pulled out, and the impurities can be cleaned, and the rubber cone plug 212 can be pulled out from the top of the water storage tank 21, and dust reduction water can be added to the inner cavity of the water storage tank 21. The dust reduction water can be initially filtered through the design of the stainless steel filter cartridge 213.

[0023] As an implementation method in this embodiment, Figure 1 and Figure 4 As shown, a connecting arm 26 is welded to the front of the water storage tank 21, and a height-fixing platform 261 is fixedly installed on the outer wall of the connecting arm 26, and a telescopic cylinder 262 is fixedly installed on the top of the height-fixing platform 261. The moving end of the telescopic cylinder 262 extends to the bottom of the height-fixing platform 261 and is fixedly connected to a lifting platform 27, and a sliding arm 1 263 is welded to the top of the lifting platform 27, and the outer wall of the sliding arm 1 263 is slidably connected to the inner wall of the height-fixing platform 261, and an elastic member 271 is fixedly connected to the bottom of the lifting platform 27, and a supporting frame 272 is fixedly connected to the bottom of the elastic member 271, and a sliding arm 273 is welded to the top of the supporting frame 272, and the outer wall of the sliding arm 273 is slidably connected to the inner wall of the lifting platform 27, and a driving motor 276 is fixedly installed on the back of the supporting frame 272.

The output shaft of the driving motor 276 is fixedly connected to the back surface of the rotating shaft 274. The sliding arm 273 is used to limit the vertical movement of the supporting frame 272. The elastic force of the elastic member 271 can cause the bottom of the grinding roller 275 to fit closely with the roadbed. After the grinding roller 275 is worn, its outer diameter will become smaller. At this time, a certain gap will be generated between the grinding roller 275 and the roadbed. The elastic force of the elastic member 271 can automatically eliminate the worn gap, so that the bottom of the grinding roller 275 can always fit closely with the roadbed. The telescopic cylinder 262 is controlled to be extended and retracted to adjust the height of the grinding roller 275. The driving motor 276 is controlled to work to drive the grinding roller 275 to rotate, thereby realizing the grinding function.

[0024] Working principle: Control the telescopic cylinder 262 to extend and retract, adjust the height of the grinding roller 275, make the bottom of the grinding roller 275 fit closely with the roadbed, and then control the drive motor 276 to work, drive the grinding roller 275 to rotate, and realize the grinding function. During the grinding process, control the pump 22 to work, extract the water in the water storage tank 21, and spray the water from the atomizing nozzle to the grinding area to carry out dust reduction treatment.

[0025] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
