[0029] In this embodiment: the dust reduction mechanism includes a water spray box 201 arranged on the rear side of the frame 100, two symmetrical water spray pipes 202 are provided at the lower end of the water spray box 201, a water inlet pipe 203 is provided at the upper end of the water spray box 201, and a circulation component for recycling the sprayed water source is provided on the rear side of the water spray box 201.

[0030] The circulation component includes a circulation box 205 arranged on the rear side of the water spray box 201, a water pump 204 is arranged on the front side of the circulation box 205, a retractable water outlet hose is connected between the water pump 204 and the water spray box 201, a water suction hose is connected between the water pump 204 and the circulation box 205, a sewage pump 206 is arranged above the circulation box 205, a water outlet pipe is arranged between the sewage pump 206 and the circulation box 205, an L-shaped water suction pipe 207 is arranged on the rear side of the sewage pump 206, a gathering component for gathering the sprayed water source is arranged on the lower side of the frame 100, and a filtering component for filtering the water source is arranged in the circulation box 205.

[0031] The gathering assembly includes two symmetrical baffles 215 slidably arranged at the bottom of the frame 100 . The two baffles 215 are inclined on one side close to each other. A baffle plate 214 is fixed between the front and rear sides of the two baffles 215 . A cylinder 213 is provided between the baffle plate 214 and the inner wall of the frame 100 .

[0032] The filtering component includes a filter 208 slidably arranged inside the circulation box 205, a compression spring is connected between the filter 208 and the inner wall of the circulation box 205, a button 209 is provided on the inner wall of the circulation box 205 near the bottom of the filter 208, a cover door 211 is rotatably installed on the side wall of the circulation box 205, an electromagnet 212 is provided at the front end of the circulation box 205 near the cover door 211, the cover door 211 is made of iron, and a cleaning component for cleaning the filter 208 is provided at the upper end of the filter 208.

[0033] The cleaning component includes a cleaning plate 210 slidably arranged on the upper end of the filter 208, a tension spring is connected between the cleaning plate 210 and the filter 208, and a pull ring is fixed on the side wall of the cleaning plate 210. A large amount of dust will be generated when the road surface is cut and repaired during road construction. The dust is processed by the dust reduction mechanism in the form of water spraying, and impurities such as stones washed on the road surface are cleaned. The sprayed water is then gathered by the circulation component and the used water source is sucked and filtered for recycling, thereby reducing the impact of dust in the environment on the staff, ensuring the cleanliness of the road surface, and at the same time improving the utilization rate of water sources, achieving the effect of saving use.

[0034] Working principle: first move the frame 100 to the use position, then drive the hydraulic cylinder 301 to drive the connecting frame 302 to move downward, drive the lower end of the cutting disk 304 to press against the road surface, and then drive the rotating motor 305 to drive the cutting disk 304 to rotate. As the hydraulic cylinder 301 continues to move downward, the road is cut under the high-speed rotation of the cutting disk 304. The protective cover 303 can reduce the splashing of small particles such as stones during cutting and provide a certain degree of protection.

[0035] While slitting, the water source inside the water box 201 is sent to the water pipe 202, and the water pipe 202 is used to spray water on the surface of the slitting disk 304 to reduce the high temperature generated by the slitting disk 304. At the same time, the sprayed water can reduce the dust generated during slitting, reducing the impact of dust on the workers and the environment. At the same time, the water source can also flush the dust and other impurities in the gap after slitting, reducing the impurities remaining in the gap, and then drive the cylinder 213 to drive the baffle 214 and the baffle 215 to move downward. The cooperation between the baffle 215 and the baffle plate 214 is used to gather and block the local water source sprayed out during the cutting to prevent the water source from flowing around, and then the used water source is pumped into the circulation box 205 through the sewage pump 206, and the impurities in the water source are filtered by the filter 208 in the circulation box 205. The filtered water source is then pumped into the water spray box 201 again through the water pump 204, and the water source is recycled, thereby improving the utilization rate of the water source and achieving the effect of saving use.

[0036] When there are more and more impurities on the filter 208, the filter 208 will be driven to move downward. When the filter 208 touches the button 209, it means that the impurities need to be cleaned, and then the electromagnet 212 is driven to cut off the power, and the cover door 211 is automatically opened. Then the staff uses a handheld tool to pull out the cleaning plate 210 above the filter 208, and pull the cleaning plate 210 to move on the filter 208 to hold the impurities above the filter 208 outside, and clean the impurities above the filter 208 to prevent the impurities from affecting the filtering efficiency of the filter 208. After cleaning, the filter 208 resets upward and no longer touches the button 209. Then the electromagnet 212 is re-energized to generate magnetism, and the cover door 211 is re-adsorbed on the side wall of the circulation box 205, the circulation box 205 is closed, and the device continues to work.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
