In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 3 As shown, this embodiment of the road maintenance crack sealant includes a base plate 1, on which a power supply box is installed for easy movement of the device. A material box 2 is mounted on the upper end of the base plate 1 via a support frame. The material box 2 is used to hold the crack sealant. A heating plate 3 is installed on the inner wall of the material box 2, which can preserve the crack sealant inside the material box 2 for a long time. A stirring component is installed inside the material box 2 to stir the crack sealant. A crack sealing pipe 5 is installed in front of the material box 2 to inject the crack sealant into the road cracks. A blower 6 is installed on the upper end of the base plate 1 on one side of the material box 2. A three-way pipe 7 is installed at the output end of the blower 6. One end of the three-way pipe 7 is connected to a heating box 8. Air ducts 9 are installed at one end of the heating box 8 and the other end of the three-way pipe 7. Air blowing pipes 10 are installed at one end of each air duct 9. The blower 6 blows air into the heating box 8. The heating box 8 can heat the air, so that the air blown by one air pipe 10 is hot air with a certain temperature. The hot air can not only blow away and clean the impurities in the road cracks, but also soften the road cracks, making it easier for the sealant to adhere to the road cracks. At the same time, the air blown out from the other air pipe 10 can quickly cool the sealant after the sealant is filled, effectively reducing the subsequent waiting time. The sealant pipe 5 is located between the two air pipes 10, and both the sealant pipe 5 and the two air pipes 10 are located on the front side of the base plate 1. By placing the sealant pipe 5 on the front side of the base plate 1, it is easy for the staff to check and effectively prevents the staff from accidentally stepping on the sealant. An adjustable pressure roller 11 is installed between the sealant pipe 5 and the air pipe 10. The pressure roller 11 is used to squeeze the sealant, so that the sealant and the road are kept at the same height.

[0021] Specifically, the mixing assembly includes a mixing motor 401, a mixing shaft 402, and mixing rods 403. The mixing motor 401 is installed at the upper end of the material box 2, and the mixing shaft 402 is installed inside the material box 2 at the output end of the mixing motor 401. Several mixing rods 403 are installed on the surface of the mixing shaft 402. By using the mixing motor 401 to drive the mixing shaft 402 to rotate, the mixing shaft 402 can agitate the sealant, effectively preventing the sealant from solidifying inside the material box 2.

[0022] Furthermore, a heating tube 12 is installed inside the heating box 8. The heating tube 12 is a resistance wire heating tube, which can quickly heat the air so that the air blown out by the air blowing pipe 10 is hot air with a certain temperature.

[0023] Furthermore, a fixing plate 13 is installed at the front end of the base plate 1 between the sealing pipe 5 and the air blowing pipe 10. An adjusting screw 14 is installed on the upper end of the fixing plate 13 through a screw hole. A mounting seat 15 is rotatably installed on the lower end of the adjusting screw 14. The pressure roller 11 is rotatably installed on the lower end of the mounting seat 15. Guide rods 16 are installed on the upper ends of the mounting seats 15 at both the front and rear ends of the adjusting screw 14. The upper ends of the guide rods 16 pass through the fixing plate 13 through through holes. An adjusting handle 17 is installed on the upper end of the adjusting screw 14. By rotating the adjusting handle 17, the adjusting screw 14 is driven to rotate. The adjusting screw 14 can drive the mounting seat 15 to rise and fall, which is convenient for adjustment according to the usage height of the pressure roller 11. The setting of the guide rod 16 plays a guiding role in the movement of the mounting seat 15.

[0024] Furthermore, the pressure roller 11 is located between the air blowing pipe 10 and the joint filling pipe 5 on the side away from the heating box 8. The pressure roller 11 is used to flatten the joint filling agent filled into the road joint, so that the joint filling agent and the road are kept on the same plane.

[0025] Furthermore, four casters 18 are mounted in a rectangular array at the lower end of the base plate 1, and a push rod 19 is mounted on the upper end of the base plate 1 away from the heating box 8. The casters 18 facilitate the movement of the device, and the push rod 19 facilitates the pushing of the device. The installation direction of the push rod 19 effectively prevents workers from stepping on the sealant after the sealant has been applied.

[0026] The method of use in this embodiment is as follows: the sealant is added into the material box 2, and the bottom plate 1 is moved by the push rod 19. During this process, the stirring motor 401 drives the stirring shaft 402 to rotate. The stirring shaft 402 can stir the sealant, effectively preventing the sealant from solidifying inside the material box 2. At the same time, the blower 6 blows air into the two air pipes 9 through the three-way pipe 7. The air inside one air pipe 9 is blown into the heating box 8, and the heating tube 12 inside the heating box 8 is heated. The air is heated so that the air blown out by one air pipe 10 is hot air. The hot air can blow away and clean the impurities in the road cracks. At the same time, the hot air can soften the road cracks. After softening and cleaning, the cracks are filled with sealant through the sealant pipe 5. Then, the sealant is compacted by the pressure roller 11. At the same time, the air blown out by another air pipe 10 can blow the sealant to accelerate the solidification of the sealant in the road cracks and effectively reduce the subsequent waiting time. This completes the use of this device.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
