[0002] "CN219410472U" discloses "an asphalt road repair and leveling device, comprising: a chassis; an asphalt repair mechanism, which is arranged on the chassis and contains asphalt for paving the damaged part of the asphalt road... a heating coil is arranged in the heating chamber." The damaged part of the road is repaired and laid by the asphalt repair mechanism and the asphalt in the asphalt repair mechanism is assisted by a water heating mechanism. After the repair and paving is completed, the repaired and paved part is leveled by the leveling mechanism. A device realizes multifunctional repair operations, which is practical and convenient.

[0003] With respect to the above-mentioned related technologies, the inventors believe that when asphalt passes through the conical discharge port and the asphalt paving port, the asphalt will adhere to the inner wall of the conical discharge port and the asphalt paving port due to its own viscosity, thereby causing blockage and affecting the discharge efficiency. In addition, when the asphalt is leveled by pressing down with a screed, the equipment needs to be stopped for a period of time. When a large area needs to be leveled, the work efficiency of road repair will be reduced. Therefore, an asphalt road repair and leveling device is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0025] A servo motor 22 is fixedly mounted on one side outer wall of the paving box 18 , the output end of the servo motor 22 passes through the paving box 18 and is fixedly connected to one end of the rotating shaft 20 , and a paving opening 19 is provided on the bottom outer wall of the paving box 18 .

[0026] A mounting frame 7 is fixedly connected to the bottom outer wall of the base plate 1 , and a scattering rake 8 is fixedly connected to the bottom outer wall of the mounting frame 7 . The scattering rake 8 is located between the second leveling roller 5 and the paving box 18 .

[0027] Two moving wheels 6 are installed on the bottom outer wall of the bottom plate 1 , and the two moving wheels 6 are in the same horizontal plane as the bottoms of the first leveling roller 3 and the second leveling roller 5 .

[0028] A connecting ring 9 is fixedly connected to the bottom outer wall of the bottom plate 1 , and the connecting ring 9 is located between the two moving wheels 6 .

[0029] The bottom outer wall of the bottom plate 1 is fixedly connected to a first fixing frame 2, a first leveling roller 3 is rotatably connected to the inner wall of the first fixing frame 2, the bottom outer wall of the bottom plate 1 is fixedly connected to a second fixing frame 4, and a second leveling roller 5 is rotatably connected to the inner wall of the second fixing frame 4.

The bottom ends of the plurality of support columns 12 are fixedly connected to the top outer wall of the bottom plate 1 .

[0031] The implementation principle of the asphalt road repair and leveling device of the embodiment of the present application is as follows: when in use, asphalt is added into the mixing box 11 through the feed port 13, and the drive motor 16 is started. The output end of the drive motor 16 drives the connecting shaft 14 to rotate. The rotation of the connecting shaft 14 drives the multiple stirring rods 15 to rotate to stir the asphalt to prevent the asphalt from solidifying. The rotation of the connecting shaft 14 also drives the threaded conveying rod 17 to rotate inside the discharge port 10, thereby evenly conveying the asphalt inside the mixing box 11 to the paving box 18. The rotation of the threaded conveying rod 17 can continuously stir the asphalt adhered to the inner wall of the discharge port 10 and squeeze it to convey it downward, effectively preventing the asphalt from being blocked at the discharge port 10. When the asphalt enters the paving box 18, the servo motor 22 is started, and the output end of the servo motor 22 drives the rotating shaft 20 to rotate. The rotation of the rotating shaft 20 drives multiple arc-shaped dividing plates 21 to rotate around the rotating shaft 20, and the asphalt falling into the paving box 18 is evenly discharged to the paving port 19, and then the asphalt is evenly spread on the road to be repaired from the paving port 19;

[0032] At this time, the device is connected to an external driving device through a connecting ring 9, and the driving device drives the device to move. When the base plate 1 moves, it drives the two moving wheels 6, the first leveling roller 3 and the second leveling roller 5 to rotate on the ground. When the asphalt is spread from the paving opening 19, as the dispersion harrow 8 moves closer, the asphalt is evenly dispersed on the road surface. Then the second leveling roller 5 first rolls and levels the asphalt, and then the first leveling roller 3 rolls and levels the asphalt again. The asphalt is leveled twice, which improves the leveling effect, thereby achieving automatic leveling when paving asphalt, without stopping for leveling, and improving overall work efficiency.
