[0037] When in use, the device is pushed to the position of the crack that needs to be repaired, and the bottom pipe opening of the delivery pipe 20 is aligned with the crack position. At this time, the crack can be filled. By opening the valve in the asphalt storage box 23, the asphalt concrete can flow out along the delivery pipe 20. By holding the handle 10 and moving it back and forth, the movable shaft 17 can be driven to move, and the movable shaft 17 drives the slider 16. The slider 16 drives the delivery pipe 20 and the movable plate 12 to move back and forth, so that the crack can be effectively filled. If the crack is too wide, the handle 10 can be pushed left and right while moving it back and forth, so that the slider 16 slides left and right on the movable plate 12, and the wider crack can be effectively filled. The moving assembly avoids the need to constantly move the vehicle body every time filling is performed, and filling is very convenient.

[0038] When the cracks are filled, the mobile box 1 can be pushed so that the flattening roller 19 rolls the filled area to flatten the asphalt concrete. The weight of the flattening roller 19 can be adjusted for different cracks. The valve in the upper sand conveying pipe 21 is opened to allow the sand in the upper sand storage box 3 to flow into the counterweight box 4. The weight of the counterweight box 4 is controlled by controlling the mass of the sand flowing in. When the weight of the counterweight box 4 needs to be reduced, the valve in the bottom sand conveying pipe 21 is opened, and the sand in the counterweight box 4 flows out to the sand storage box 3 below, thereby reducing the weight of the counterweight box 4. When the sand in the upper sand storage box 3 flows into the lower sand storage box 3, the fixing rod 8 is pulled outward to disengage the fixing hole 9, and then the upper and lower sand storage boxes 3 are driven to rotate and exchange positions by rotating the rotating handle 6, and the rotating disk 22 also rotates accordingly. After exchanging positions, the fixing rod 8 is released, and the fixing rod 8 enters the fixing hole 9 under the action of the spring 11 to limit the sand storage box 3 again.
