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

[0021] like Figures 1 to 4 As shown, the pavement repair device of this embodiment includes a road repair vehicle 1, a cement box 2 is installed on the upper end of the road repair vehicle 1, the interior of the cement box 2 is used to store cement, a driving motor 4 is installed on the upper end of the cement box 2, the driving motor 4 is a servo motor commonly seen on the market, the cement box 2 provides a support effect for the driving motor 4, the output end of the driving motor 4 passes through the cement box 2 and extends into the interior of the cement box 2, and the output end below the driving motor 4 is installed with a stirring shaft 16 that passes through the interior of the cement box 2, and a surface array of the stirring shaft 16 is installed with a plurality of stirring blades 17, which are driven by The motor 4 can drive the stirring shaft 16 and the stirring blade 17 to rotate. Two connecting blocks 5 are symmetrically installed at the lower end of the road repair vehicle 1. Moving wheels are installed on both side surfaces of the connecting blocks 5. The two connecting blocks 5 are installed with a total of four moving wheels for driving the road repair vehicle 1 to move. A front baffle 6 is installed at the left end of the left connecting block 5. A discharge port 8 is installed on one side of the front baffle 6 through a hose 18. The hose 18 is communicated with the cement box 2. A cement delivery pump is provided at the connection between the hose 18 and the cement box 2, which can draw cement inside the cement box 2 into the inside of the hose 18.

[0022] Specifically, a mounting groove 11 is provided at the lower end of the connecting block 5, and a rotating shaft 12 is fixedly installed inside the mounting groove 11. A roller 10 is rotatably connected to the surface center of the rotating shaft 12. A groove 13 is provided on the inner wall surfaces of both sides of the mounting groove 11. A spring telescopic rod 14 is installed at one end of the groove 13 close to the road repair vehicle 1, and the other end of the spring telescopic rod 14 is connected to the surface of the rotating shaft 12. By arranging the roller 10 at the lower end of the connecting block 5, under the action of the two spring telescopic rods 14, the rotating shaft 12 can drive the roller 10 to move vertically inside the mounting groove 11, so that the roller 10 can be applied to different undulating roads, and has a wider applicability.

[0023] Furthermore, a limiting structure 9 is installed on both sides of the road repair vehicle 1, and the limiting structure 9 includes a fixed block 901, a threaded rod 902 and a grounding block 903.

When not in use, the hose 18 is placed inside the mounting frame 7, and the limiting ring 15 can be used to limit the position of the hose 18, so that the hose 18 can be placed inside the mounting frame 7. It should be noted that the material of the mounting frame 7 is a plastic material that can be deformed to a certain extent, and an opening needs to be opened at one end of the surface of the mounting frame 7, and the size of the opening needs to be slightly smaller than the size of the hose 18.

[0025] The method of using this embodiment is as follows: by installing a mobile power supply inside the road repair vehicle 1, when the road surface needs to be repaired, cement is put into the cement box 2, and the cement inside the cement box 2 is discharged into the inside of the road surface gap through the hose 18 and the discharge port 8 by the cement delivery pump, and at the same time, the drive motor 4 is started, and the drive motor 4 drives the stirring shaft 16 and the stirring blade 17 to rotate, thereby continuously stirring the cement inside the cement box 2 to extend the solidification time of the internal cement and increase the working time. When filling the road surface with cement, it is necessary to adjust the height of the threaded rod 902 and the grounding block 903 so that the grounding block 903 is in contact with the ground to prevent the road repair vehicle 1 from moving. After the filling is completed, the height of the grounding block 903 is raised, and the two rollers 10 of the road repair vehicle 1 are driven to move to flatten the repaired ground.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
