[0026] A rectangular plate 1, a scraper 2 is movably connected inside the rectangular plate 1, the bottom of the scraper 2 passes through the rectangular plate 1 and extends to the bottom of the rectangular plate 1, a protection box 3 located below the rectangular plate 1 is fixedly connected to the right side of the scraper 2, and the top of the protection box 3 is movably connected to the bottom of the rectangular plate 1;

[0027] An expansion mechanism, the expansion mechanism is arranged inside the protection box 3;

[0028] Among them, the expansion mechanism includes a driving motor 4, which is fixedly installed inside the protective box 3. The other end of the output shaft of the driving motor 4 is fixedly sleeved with a rotating shaft 5. The left side of the rotating shaft 5 passes through the protective box 3 and the scraper 2 in sequence and extends to the inside of the scraper 2 and is fixedly connected with a rotating block 6. The right side of the rotating block 6 is movably connected to the right side of the inner cavity of the scraper 2. The top and bottom of the front side of the rotating block 6 are hinged with connecting rods 7. The other end of the connecting rod 7 is hinged with a movable plate 8. There are two movable plates 8. The outer surfaces of the two movable plates 8 are movably connected to the inner surface of the scraper 2. The two movable plates 8 move away from each other to expand the area of ​​the scraper 2.

[0029] When the driving motor 4 is running, the rotating shaft 5 drives the rotating block 6 to rotate, and then the two connecting rods 7 rotate to drive the two movable plates 8 to move away from each other, thereby achieving the purpose of adjusting the width of the scraper 2.

[0030] A limiting groove 9 is provided inside the scraper 2, and the inner surface of the limiting groove 9 is movably connected to a limiting block 10. There are four limiting blocks 10, and the inner sides of the four limiting blocks 10 are fixedly connected to the outer sides of the two movable plates 8 respectively.

[0031] The design of the limiting groove 9 and the limiting block 10 plays a role in limiting the movable plate 8 .

[0032] A transmission motor 11 is fixedly connected to the top of the rectangular plate 1 , a transmission shaft 12 is fixedly sleeved on the other end of the output shaft of the transmission motor 11 , and a rotating rod 13 is fixedly sleeved on the outer surface of the transmission shaft 12 .

[0033] When the transmission motor 11 is running, the transmission shaft 12 will drive the rotating rod 13 to rotate.

[0034] Among them, the other end of the rotating rod 13 is fixedly sleeved with a round shaft 14, and the outer surface of the round shaft 14 is movably connected with a rectangular block 15. The bottom of the rectangular block 15 is fixedly connected to the top of the scraper 2. The downward movement of the rectangular block 15 pushes the scraper 2 to move downward.

[0042] The working principle and use process of this utility model:

[0043] When repairing an asphalt pavement, first start the transmission motor 11, which will cause the transmission shaft 12 to drive the rotating rod 13 to rotate, and then the circular shaft 14 will rotate to drive the rectangular block 15 to move downward, so that the scraper 2 moves downward, achieving the purpose of automatically adjusting the scraper 2 to rise and fall. When the scraper 2 contacts the asphalt pavement, the push rod 16 is then pushed, and the rectangular plate 1 is driven to move with the cooperation of the four round wheels 17, so that the scraper 2 paves the asphalt, thereby achieving the purpose of repairing the damaged road surface.

[0044] When the width of the damaged road surface is greater than the width of the scraper 2, starting the drive motor 4 will cause the rotating shaft 5 to drive the rotating block 6 to rotate, and then the two connecting rods 7 will rotate to drive the two movable plates 8 to move away from each other, thereby achieving the purpose of adjusting the width of the scraper 2, so that the asphalt on the damaged road surface can be quickly scraped flat.
