[0029] It should be noted that through the setting of the scraping plate 12, the included angle position between the scraping plate 12 and the road surface can be adjusted according to actual requirements, so as to scrape and level the excess materials, thereby improving the crack sealer flatness of the road.

[0030] Furthermore, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , specifically, the cleaning component 4 includes a blower 41, the blower 41 is fixed on the side wall of the top end of the load-bearing plate 1, an air outlet pipe 42 is fixed at the output end of the blower 41, a jet nozzle 43 is fixed at the end of the air outlet pipe 42 away from the blower 41, and a filter cylinder 44 is fixed at the input end of the blower 41; two bearing seats 45, the two bearing seats 45 are symmetrically distributed and fixed on the side wall of the bottom end of the load-bearing plate 1, a brush roller 46 is rotatably connected to the side wall of one side of the two bearing seats 45, a base plate 47 is fixed on the side wall of the top end of the load-bearing plate 1, a driving motor 48 is fixed on the side wall of the top end of the base plate 47, a belt pulley 49 is fixed between one end of the output shaft of the driving motor 48 and the brush roller 46, and a belt 410 is jointly sleeved on the outer surfaces of the two belt pulleys 49;

[0031] It should be noted that by setting the cleaning component 4, the road surface that needs to be caulked can be cleaned. The cracks are cleaned by the synchronous cooperation of two methods: jetting and sweeping, so as to double-clean the impurities in the cracks to maintain the cleaning effect of the cracks before caulking, improve the bonding performance and filling quality between the asphalt and the road after caulking, and make the crack cleaning work more time-saving and labor-saving for the staff.

[0032] Furthermore, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 it is worth specifically explaining that the stirring component 7 includes a bracket 71. The bracket 71 is fixed to the inner side wall of the mixing cylinder 6. A servo motor 72 is fixed to the top side wall of the bracket 71.

[0033] It should be noted that by setting the stirring component 7, the materials can be fully mixed and stirred, effectively improving the service time of the materials, and then improving the working effect of the crack filling and powder construction, effectively preventing the materials from solidifying or hardening, and then improving the quality of the crack caulking work. This device has strong flexibility and can perform mixing operations on the materials according to actual requirements.

[0034] This solution has the following working process: When technicians use this device, the raw materials are poured into the mixing cylinder 6 from the hopper 76. Driven by the servo motor 72, the driving shaft 73 rotates synchronously, driving the frame-type stirring rod 74 and the stirring rods to rotate synchronously, so as to complete the mixing and stirring of the raw materials in the mixing cylinder 6. Driven by the fan 41, the air is extracted and pressurized by the air filter cylinder 44, and the pressurized air is output from the air outlet pipe, and the pressurized air is sprayed onto the road cracks by the air spraying pipe. Driven by the driving motor 48, using the transmission effect of the belt pulley 49 and the belt 410, the brush roller 46 rotates synchronously, and the brush roller 46 sweeps the road cracks, so as to complete the cleaning work of the road cracks. By rotating the runner 16, the threaded rod 14 rotates synchronously. Using the threaded transmission effect between the threaded rod 14 and the threaded sleeve 13, the threaded rod 14 moves downward under force, causing the scraper 12 to flip along the axis of the rotating rod 11, ensuring that the scraper 12 is in contact with the ground. By opening the valve 9, the mixed materials in the mixing cylinder 6 are discharged from the discharge pipe 8, and the device is pushed to move along the road cracks, so as to complete the caulking construction operation.

[0035] According to the above working process, it can be known that: through the setting of the cleaning component 4, the road surface that needs crack filling construction can be cleaned. The cracks are cleaned by the synchronous cooperation of two methods, namely jetting and sweeping, so as to double clean the impurities in the cracks to maintain the cleaning effect of the cracks before crack filling, improve the bonding performance and filling quality between the asphalt and the road after crack filling. For the staff, the work of cleaning the cracks is more time-saving and labor-saving. And through the setting of the stirring component 7, the materials can be fully mixed and stirred, effectively improving the service time of the materials, and then improving the working effect of the crack powder filling construction, effectively preventing the materials from solidifying or hardening, and then improving the quality of the crack patching work. This device has strong flexibility and can perform the mixing operation on the materials according to the actual requirements.

[0036] Further, as shown in Figure 3 and Figure 4 , it is worth specifically stating that the brush roller 46 is located on one side of the air jet nozzle 43, and the inner bottom wall of the hopper 76 is provided with a chamfered inclined surface;

[0037] It should be noted that through the setting of the chamfered inclined surface of the hopper 76, it can ensure that the raw materials can smoothly slide into the mixing cylinder 6, and then improve the feeding speed of the materials.

[0038] Further, as shown in Figure 2 and Figure 3 , it is worth specifically stating that one side of the scraper 12 is provided with a chamfered inclined surface, and the side of the scraper 12 close to the installation groove 10 is provided with a smooth arc surface;

[0039] It should be noted that through the setting of the scraper 12, the excess materials at the crack are scraped flat, so as to ensure the flatness of the crack patching construction operation, and then improve the crack filling construction effect.

[0040] Further, as shown in Figure 1 and Figure 2 , it is worth specifically stating that the vertical section of the mixing cylinder 6 is arranged in an inverted trapezoid shape, and the discharge pipe 8 is arranged in a curved shape;

[0041] It should be noted that through the setting of the mixing cylinder 6, the situation of materials staying in the mixing cylinder 6 is avoided, and it is ensured that the materials can be smoothly and fluently discharged from the discharge pipe 8.

[0042] In summary: through the setting of the chamfered inclined surface of the hopper 76, it can ensure that the raw materials can smoothly slide into the mixing cylinder 6, and then improve the feeding speed of the materials. And through the setting of the scraper 12, the excess materials at the crack are scraped flat, so as to ensure the flatness of the crack patching construction operation, and then improve the crack filling construction effect. And through the setting of the mixing cylinder 6, the situation of materials staying in the mixing cylinder 6 is avoided, and it is ensured that the materials can be smoothly and fluently discharged from the discharge pipe 8.

The fan 41, the drive motor 48, and the servo motor 72 are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed.
