[0029] An asphalt road pothole treatment device, as Figure 1 and Figure 2 shown, includes:

[0030] A carrier 10, a frame structure with rollers. Specifically, the carrier 10 includes a rectangular plate at the top and support legs fixedly installed at the bottom of the rectangular plate. The rollers are movably connected to the support legs, and a handle is fixedly provided on one side of the rectangular plate;

[0031] The cutting assembly 11 is provided at the bottom of the carrier 10 for cutting the road surface. The cutting assembly 11 includes a motor and a cutting blade fixedly installed on the output shaft of the motor. The cutting of the road surface by the cutting assembly 11 realizes the treatment of potholes on the asphalt road surface, so that the potholes form regular shapes for easy repair. The specific models and specifications are not elaborated here.

[0032] As Figure 2 and Figure 3 shown, the protection assembly is provided at the bottom of the carrier 10 and forms a protection barrier around the cutting assembly 11. The protection assembly can adsorb the dust generated by the cutting of the cutting assembly 11. The protection assembly includes a bottom box 20, a sliding plate 21 and a negative pressure box 23. The bottom box 20 is movably connected to the carrier 10. The bottom box 20 has a cavity. The cutting assembly 11 is located inside the bottom box 20. An adsorption chamber is formed inside the bottom box 20. The negative pressure box 23 is fixedly connected to the carrier 10. The inside of the negative pressure box 23 is hollow. A blower is fixedly provided on one side of the negative pressure box 23. The chamber of the negative pressure box 23 is communicated with the chamber of the bottom box 20. A plurality of sliding plates 21 are elastically connected to the bottom of the bottom box 20. The plurality of sliding plates 21 together form a rectangular protection barrier around the cutting assembly 11. The sliding plate 21 can abut against the ground. A push cylinder is fixedly installed on the top of the carrier 10. A truss is installed on the output shaft of the push rod. A connecting seat is fixedly provided at the output end of the truss. Both the cutting assembly 11 and the bottom box 20 are fixedly connected to the bottom of the connecting seat. The truss is a biaxial truss, that is, it realizes the pushing of the cutting assembly 11 in the X and Z axis directions, and cooperates with the push cylinder to adjust the position of the cutting assembly 11 in the Y axis direction to realize multi-axis adjustment. The blower is a negative pressure blower, which can be a duct blower. The specific specifications are not limited here.

[0033] In this solution, by setting the bottom box 20, the four sliding plates 21 at the bottom of the bottom box 20 abut against the bottom surface. The four sliding plates 21 and the bottom box 20 together surround the cutting assembly 11, so that a relatively sealed environment is formed around the cutting assembly 11. By pumping air from the chamber of the bottom box 20 by the negative pressure box 23, the dust generated during the cutting of the cutting assembly 11 is sucked into the negative pressure box 23 for collection, reducing the air pollution caused by the dust diffusion during the cutting process. At the same time, the four sliding plates 21 can always abut against the bottom surface. When the cutting assembly 11 cuts the road surface, it can reduce the splashing caused by the cutting pieces throwing the debris, improving the protection effect during the cutting process.

[0034] As Figure 3 and Figure 5As shown in the figure, the protection component further includes a connecting pipe 24 and an air suction pipe 25. The air suction pipe 25 is fixedly connected to the negative pressure box 23, and the connecting pipe 24 is fixedly connected to the bottom box 20. A hose is fixedly arranged between the air suction pipe 25 and the negative pressure box 23. The air suction pipe 25 forms an L-shaped pipe structure, and the negative pressure box 23 forms a rectangular box body. The bent part of the air suction pipe 25 extends towards the bottom of the negative pressure box 23 and does not contact the bottom of the negative pressure box 23. The fan is arranged on the side away from the air suction pipe 25 and the installation height of the fan is higher than the port of the air suction pipe 25. Through the design of the bend of the air suction pipe 25, the mixture of wind and dust sucked into the negative pressure box 23 is discharged towards the bottom of the negative pressure box 23. Water is injected into the negative pressure box 23, and the dust is adsorbed and washed by the water. A water pipe is fixedly installed on the back of the negative pressure box 23, and a ball valve is provided at the port of the water pipe for easy filling and draining. The air suction pipe 25 is connected to the connecting pipe 24 through a hose. The hose can be a metal corrugated pipe, which will neither interfere with the lifting movement of the bottom box 20 nor affect the sealing performance of the connection between the connecting pipe 24 and the air suction pipe 25.

[0035] As Figure 4 shown in the figure, four sliding channels 26 are opened at the bottom of the bottom box 20. The sliding plate 21 is slidably connected to the corresponding sliding channel 26. The sliding channel 26 forms a notch adapted to the sliding plate 21. An elastic member is arranged in the sliding channel 26. The elastic member includes a spring but is not limited to a spring. One end of the spring is fixedly connected to the inner top surface of the bottom box 20, and the other end of the spring is fixedly connected to the top of the sliding plate 21. By arranging the sliding channel 26, the spring pushes the sliding plate 21 to slide in the corresponding sliding channel 26, realizing the elastic connection between the sliding plate 21 and the bottom box 20, ensuring the fitting effect between the sliding plate 21 and the ground and thus ensuring the dust suction effect, and at the same time greatly reducing the probability of debris splashing.

[0036] As Figure 4 shown in the figure, the protection component further includes an extrusion plate 22. The extrusion plate 22 forms a rod structure with a V-shaped horizontal cross-section. A connecting rod is fixedly arranged on one side of the extrusion plate 22, and the connecting rod is fixedly connected to one side of the bottom box 20. The extrusion plate 22 is arranged, and the tip of the extrusion plate 22, that is, the ridge line of the extrusion plate 22, faces the driving direction of the carrier 10. Through the extrusion plate 22, large debris on the road surface at the position about to be cut by the cutting component 11 can be pushed to both sides, reducing the interference caused by the large debris during the cutting of the cutting component 11 and ensuring the stability and accuracy of the cutting.

[0037] Working principle of the utility model: Through the bent design of the suction pipe 25, the wind and dust mixture sucked into the negative pressure box 23 is discharged towards the bottom of the negative pressure box 23. Water is injected into the negative pressure box 23, and the dust is adsorbed and washed by water. A water pipe is fixedly installed on the back of the negative pressure box 23, and a ball valve is provided at the port of the water pipe for easy filling and drainage. The suction pipe 25 is connected to the connecting pipe 24 through a hose. The hose can be a metal corrugated pipe, which will neither interfere with the lifting movement of the bottom box 20 nor affect the sealing performance of the connection between the connecting pipe 24 and the suction pipe 25. By providing the sliding channel 26, the spring pushes the sliding plate 21 to slide in the corresponding sliding channel 26, realizing the elastic connection between the sliding plate 21 and the bottom box 20, ensuring the fitting effect between the sliding plate 21 and the ground and thus ensuring the dust suction effect. The extrusion plate 22 is provided, and the tip of the extrusion plate 22, that is, the ridge line of the extrusion plate 22, faces the traveling direction of the carrier 10. Through the extrusion plate 22, large debris on the road surface at the position where the cutting assembly 11 is about to cut can be pushed to both sides, ensuring that there are no large foreign objects at the position where the cutting assembly 11 is about to cut.
