[0032] In the disclosed embodiment, the lower rotating blocks 305 on both sides of the lower rotating plate 302 are respectively threadedly connected to the two ends of the middle threaded rod 307, and the lower rotating blocks 305 on both sides of the lower rotating plate 302 are slidably connected to the same lower cross frame 306. The middle support rod 304 supports one side of the repair agent box 3 to lift the height, and the repair agent box 3 is tilted toward the side of the lower repair tube 301. When there is less repair agent inside the repair agent box 3, the flow speed toward the lower repair tube 301 is accelerated.

[0033] In the embodiment of the present disclosure, the lower end of the lower connecting slide tube 104 of the upper handrail frame 102 on one side of the main trolley 1 is rotatably connected to the upper movable frame 2 where the air pump machine 202 is located, and the air outlet pipe 203 moves back and forth to maintain alignment with the gap. The air pump machine 202 exhausts air to realize the cleaning operation of the road surface gap, which is conducive to the subsequent filling and maintenance of the repair agent and the gap. The lower end of the lower connecting slide tube 104 of the upper handrail frame 102 on the other side of the main trolley 1 is rotatably connected to the repair agent box 3, and the lower connecting slide tube 104 drives the repair agent box 3 to move left and right with the upper movable frame 2. The repair agent box 3 moving left and right is convenient for aligning with the irregular cracks in the inclined road surface and pouring the repair agent for maintenance work. The two upper movable frames 2 in front and behind can move independently, and two people respectively perform the alignment of cleaning and pouring the repair agent, so as to realize the simultaneous cleaning and pouring of the repair agent, thereby improving the repair efficiency of the cracks.

[0034] Embodiment 2, on the basis of embodiment 1, a resistance heating module is provided inside the repair agent box 3, and the repair agent inside the repair agent box 3 is heated and operates at a high temperature to avoid the repair agent solidifying due to the temperature drop, thereby ensuring that the repair agent has good fluidity. The main cart 1 is provided with a battery to power the repair agent box 3 and the air pump 202, which can be used wirelessly to avoid dragging the power supply line, and is more convenient to use.

[0035] The working principle of this embodiment is as follows: the main cart 1 moves in the direction of the gap in the road surface, the upper rotating frame 103 at the front of the main cart 1 rotates, and the upper rotating frame 103 rotates around the connection with the upper handrail frame 102, and the upper rotating frame 103 and the lower connecting slide pipe 104 rotate synchronously, and the lower connecting slide pipe 104 drives the upper moving frame 2 to move horizontally along the main cart 1, and the upper rotating frame 103 and the lower connecting slide pipe 104 slide to extend and compress to adapt to the position change of the upper moving frame 2, and control the upper moving frame 2 to drive the air pump 202 to move back and forth, and the air outlet pipe 203 moves synchronously, and the air outlet pipe 203 moves back and forth to keep aligned with the gap, and the air pump 202 exhausts air to realize the cleaning operation of the road surface gap, which is beneficial to the subsequent repair agent and gap filling and maintenance, and the upper rotating frame 103 at the rear of the main cart 1 rotates in the same way. The upper rotating frame 103 rotates around the connection with the upper handrail frame 102, and the upper rotating frame 103 and the lower connecting slide pipe 104 rotate synchronously. The rotation of the upper rotating frame 103 and the lower connecting slide pipe 104 drives the repair agent box 3 to move left and right with the upper movable frame 2. The repair agent box 3 moving left and right is convenient for aligning with the irregular cracks of the inclined road surface and pouring the repair agent for maintenance work, eliminating the need for the main cart 1 to adjust and align with the road surface gap. The main cart 1 only needs to move within a rough range, and the main cart 1 does not need to move left and right, reducing the difficulty of the alignment operation. At the same time, the two upper movable frames 2 in front and behind can move independently, and two people can respectively clean and align the repair agent, so as to realize the simultaneous cleaning and pouring of the repair agent, thereby improving the repair efficiency of the cracks.

[0036] When the amount of repair agent inside the repair agent box 3 decreases and the flow rate of the repair agent box 3 to the lower repair pipe 301 slows down, the middle threaded rod 307 rotates to drive the lower rotating block 305 to move in the opposite direction, and the lower rotating block 305 pulls the middle support rod 304 to move in the vertical direction. The middle support rod 304 supports one side of the repair agent box 3 to lift the height, and the repair agent box 3 tilts toward the lower repair pipe 301. When there is less repair agent inside the repair agent box 3, the flow rate toward the lower repair pipe 301 is accelerated to ensure that there is a faster outflow rate when there is less repair agent inside the repair agent box 3.
