The repair material is stirred to make it more evenly mixed. One end of the discharge pipe 4 passes through the movable base 1. A first electric push rod 5 is installed at the bottom of the movable base 1 and on one side of the discharge pipe 4. The output end of the first electric push rod 5 is fixedly connected to an regulator 6. A bracket 7 is rotatably connected to the bottom of the regulator 6. Multiple nozzles 8 are fixedly connected to the outside of the bracket 7. The discharge port sizes of the multiple nozzles 8 are different, and each of the multiple nozzles 8 has an insertion port 9 at its top. One end of the discharge pipe 4 is inserted into one of the insertion ports 9 and connected to the discharge pipe 4. The operation of the cement pump 2 facilitates the extraction of the repair material from the mixing tank 27, which is then sprayed into the cracks in the road surface by the discharge pipe 4 and the nozzles 8 for repair. A first motor 10 is installed inside the regulator 6. The output end of motor 10 is fixedly connected to bracket 7, driving bracket 7 to rotate and move nozzle 8 of the required discharge port size to below discharge pipe 4. This, in conjunction with the operation of the first electric push rod 5, connects or disconnects from discharge pipe 4, facilitating the replacement of the appropriate nozzle 8 according to the width of the crack. Drive wheels 12 are installed on both sides of the bottom of the movable base 1. A camera 11 is installed on the bottom of the movable base 1, on the side of discharge pipe 4 away from the first electric push rod 5, to facilitate monitoring of crack distribution and ensure nozzle 8 is aligned with the crack. A mounting bracket 13 is installed on the bottom of the movable base 1, on the side of camera 11 away from discharge pipe 4. A brush plate 14 is fixedly connected to the bottom of the mounting bracket 13, facilitating the removal of debris from the crack as the movable base 1 moves. The mixing tank 27 has a handle on its left side. A control panel 26 is mounted on the surface of the mixing tank 27. A second electric push rod 15 is mounted on the bottom of the movable base 1, on the side of the first electric push rod 5 away from the discharge pipe 4. A first support rod 16 is fixedly connected to the output end of the second electric push rod 15. A second support rod 17 is slidably connected inside the first support rod 16.

[0023] In summary, this road maintenance and pavement repair device is powered by a portable power source. The camera 11 at the bottom of the mobile base 1 monitors the distribution of cracks and transmits the image to the display screen on the control panel. Based on the crack width, the operator controls the first motor 10 to rotate the support 7, causing the nozzle 8 with a corresponding discharge port on the support 7 to move below the discharge pipe 4. Simultaneously, the first electric push rod 5 drives the adjuster 6 and the nozzle 8 to rise, and one end of the discharge pipe 4 is inserted into the corresponding nozzle 8's inner insertion port 9, connecting with the nozzle 8. At this time, the mobile base... As the base 1 moves, the bottom brush plate 14 of the moving base 1 sweeps out some of the debris from the crack. The cement pump 2 extracts the repair material from the mixing tank 27 through the feed pipe 3, and then guides it to the nozzle 8 connected by the discharge pipe 4 and sprays it into the crack. The second electric push rod 15 pushes the first support rod 16 and the second support rod 17 down, and the pressure roller 19 and scraper 21 then come into contact with the ground. The scraper 21 scrapes the repair material overflowing from the crack and the pressure roller 19 compacts the repair material. After use, the mixing tank 27, pressure roller 19, scraper 2, nozzle 8, camera 11 and other parts are rinsed with clean water for cleaning.
