Mounting plates are provided downwardly on both sides of the middle part of the mounting frame, and the mounting plates are connected to the box body of the cleaning truck through connecting rods. A downward-inclined opening is provided at the rear end of the box body of the cleaning truck, and a shovel blade is connected to the bottom end of the opening, and the blade of the shovel blade is inclined upward to contact the surface of the pressure roller.

[0005] Preferably, connecting rods are provided on both sides of the bottom end of the above-mentioned cleaning vehicle body, located below the shovel and outward, and two limit plates are provided at the head ends of the connecting rods. Brush plates are movably connected between the limit plates, and bristles are provided on the outside of the brush plates. The bristles are in contact with the surface of the pressure roller, and a spring is connected between the inner side of the brush plate and the limit plate at the inner end.

[0006] Preferably, the blade is connected to the vehicle body via a blade holder by bolts.

[0007] Preferably, the width between the front legs of the above-mentioned mounting frame is greater than the width of the rear legs, the width of the cleaning truck box is equivalent to the pressure roller, the bottom front end of the cleaning truck box is connected to the moving wheel through the wheel frame, and the top of the fixed rod at the front end of the cleaning truck box is matched with the mounting plate to open a through hole, and a pull rod is used to pass through the mounting plate and the fixed plate from the through hole and then fixed from the outside of the mounting plate through a nut.

[0008] Preferably, the front end of the mounting bracket is connected to the operating rod, and the front end of the operating rod is connected to the ear plate.

[0009] Compared with the existing technology, the beneficial effect of the utility model is that a mounting frame is provided to install the pressure roller, a scraper is provided at the front end of the pressure roller to scrape off the gravel and mud blocks adhered to the surface of the pressure roller, and the gravel and mud blocks are removed in conjunction with the cleaning vehicle box, which is conducive to the pressure roller leveling the ground and improving the compaction effect.

[0014] The present invention will be further explained below with reference to the accompanying drawings to facilitate better understanding by those skilled in the art.

[0015] Example 1

[0016] like Figure 1-4 As shown, a leveling device for roadway repair includes a mounting frame 1. Front legs 2 and rear legs 3 are provided downwardly on both sides of the front and rear ends of the mounting frame 1, respectively. Travel wheels 4 are installed below the front legs 2 through wheel frames. Pressure rollers 5 are rotatably connected between the rear legs 3 via a rotating shaft. The bottom end surface of the pressure roller 5 is flush with the bottom end surface of the travel wheel 4. Mounting plates 6 are provided downwardly on both sides of the middle of the mounting frame 1. The mounting plates 6 are connected to a cleaning vehicle box 8 via a fixing rod 7. A downwardly inclined opening is provided at the rear end of the cleaning vehicle box 8, and a scraper 9 is connected to the bottom end of the opening. The blade of the scraper 9 is tilted upward and contacts the surface of the pressure roller 5. The mounting frame 1 is provided to mount the pressure roller 5. The scraper 9 is provided at the front end of the pressure roller 5 to scrape off gravel and mud blocks adhered to the surface of the pressure roller 5. In cooperation with the cleaning vehicle box 8, the gravel and mud blocks are removed, which is conducive to the pressure roller 5 leveling the ground and improving the compaction effect.

[0017] Connecting rods 10 are provided on both sides of the bottom of the vehicle body 8, below the blade 9 and facing outward. Two limit plates 11 are spaced apart at the ends of the connecting rods 10. A brush plate 12 is movably connected between the limit plates 11. Brushes 13 are provided on the outside of the brush plates 12, which are in contact with the surface of the pressure roller 5. A spring 14 is connected between the inside of the brush plate 12 and the limit plates 11 at the inner end. A brush is provided below the blade 9 to further remove dust that has not been scraped off and ensure a smooth surface of the pressure roller. The brush plate 12 is connected to the connecting rod 10 and is retractable, so that the bristles are always in contact with the surface of the pressure roller 5.

[0018] Furthermore, the blade 9 is bolted to the vehicle body 8 via a blade holder, making it easy to replace the blade 9 .

[0019] In order to facilitate the transportation of the cleaning truck to clean up the debris, the width between the front legs 2 of the mounting frame 1 is greater than the width of the rear legs 3, the width of the cleaning truck box 8 is equivalent to the pressure roller 5, and the bottom of the front end of the cleaning truck box 8 is connected to the moving wheel 15 through the wheel frame.
