[0025] Specifically, in the cleaning process of the broken asphalt pavement residual debris, first of all, start the two electric push rods 805 to start the cleaning process, the two electric push rods 805 drive the mounting block 806 to move down, the mounting block 806 drives the scraper 807 installed inside to move down, the scraper 807 is inserted into the broken asphalt pavement, then start the second motor 801 to start the cleaning process, the second motor 801 drives the lead screw 802 to rotate through the fixed connection with the output end, the lead screw 802 drives the moving block 803 connected with the external thread to move, with the movement of the moving block 803, the mounting block 806 also moves in the vertical direction, driving the scraper 807 gradually moves to the target area, during the movement, the outer side of the moving block 803 is equipped with two guide blocks 804, which ensures the stable movement track of the cleaning device and avoids possible deviation or uneven cleaning effect, the guide block 804 works cooperatively with the electric push rod 805 to make the two electric push rods 805 move uniformly with the mounting block 806 and the scraper 807, the scraper 807 can effectively push the debris away when it contacts with the asphalt debris, without manual intervention, the whole cleaning process is completely automated, if the scraper 807 is worn or damaged during the cleaning process, the normal function of the equipment can be restored by simple replacement operation, when replacing the scraper 807, first remove the bolts 808 between the mounting block 806 and the scraper 807, take out the original scraper 807, then install the new scraper 807 and fix the bolts 808, the whole replacement process is quick and convenient, which ensures the simplicity of maintenance and replacement parts, thereby reducing the equipment downtime and ensuring uninterrupted repair work, in addition, the cleaning device reduces the working intensity of the operator and no longer needs to arrange additional manual cleaning, which significantly shortens the waiting time between processes, which not only improves the overall efficiency of the repair work, but also reduces the possibility of human error and speeds up the whole pavement repair progress.

[0026] Please refer to the attached drawings Figure 4 -attached drawings Figure 10The feeding anti-solidification mechanism 15 comprises a third motor 1501 arranged at the top of the storage barrel 13, a rotating rod 1502 fixedly connected to the output end of the third motor 1501, the rotating rod 1502 rotatably connected to the inside of the storage barrel 13, stirring blades 1503 fixedly connected to the outside of the rotating rod 1502, a conveying pump 1504 fixedly connected to the outside of the storage barrel 13, the input end of the conveying pump 1504 fixedly connected to the inside of the storage barrel 13, a feeding pipe 1505 fixedly connected to the output end of the conveying pump 1504, a discharge port 1506 fixedly connected to the bottom of the feeding pipe 1505, a mounting ring 14 fixedly connected to the top of the storage barrel 13, the third motor 1501 fixedly connected to the mounting ring 14, a feeding port 17 fixedly connected to the top of the storage barrel 13, the two second fixing rings 16 fixedly connected to the outside of the frame 1.

[0027] Specifically, in the process of repairing the asphalt pavement, first, the repair material needed for repair is added to the inside of the device. The prepared repair material can be poured into the storage barrel 13 through the feeding port 17 located above the device. The storage barrel 13 has a sealed and heat-insulated structure, which can maintain the temperature and performance of the repair material and avoid the situation that the repair material cools too quickly or changes in viscosity during the waiting operation. After the repair material is put in, the third motor 1501 is started to start the internal stirring of the repair material. The third motor 1501 cooperates with the rotating rod 1502 fixedly connected to the output end. When the third motor 1501 operates, the rotating rod 1502 rotates. The rotating rod 1502 is uniformly fixedly connected with a plurality of stirring blades 1503 around the outside. The stirring blades 1503 will form a sufficient turning and stirring effect in the storage barrel 13 with the rotation of the rotating rod 1502. The stirring blades 1503 rotate uniformly in the entire storage barrel 13, which can continuously break the particle agglomeration part of the repair material, prevent the repair material from solidifying, precipitating or sticking due to long-term standing, and thus maintain the uniformity and fluidity of the repair material. This automatic stirring mechanism ensures that the repair material in good condition can be taken at any time without the need for operators to frequently check or reprocess the repair material, greatly reducing the amount of manual participation. When the repair material is fully stirred and maintains good fluidity, the delivery pump 1504 is then started. After the delivery pump 1504 is started, it will quickly and stably extract the repair material in the storage barrel 13 through negative pressure and pushing action. The repair material flows along the material conveying pipe 1505 under the drive of the pump. After passing through the material conveying pipe 1505, the repair material is conveyed to the discharge port 1506 at the front end of the device and discharged through the discharge port 1506. After the repair material is laid, the area that has been laid is then compacted and leveled by the leveling roller 24. The leveling roller 24 compacts the repair material to the road base through its own weight and rolling pressure, so that the repair material fully adheres to the original road surface to form a solid and flat repair layer. This step not only ensures the surface flatness of the repair area, but also improves the compactness and durability of the repair layer, avoiding problems such as depression, looseness or cracking in the later stage. Through the above operation, the entire repair process realizes automatic, continuous and efficient operation. On the one hand, the automatic stirring of the stirring blades 1503 can effectively prevent the repair material in the storage barrel 13 from solidifying and reduce repair quality problems caused by poor repair material condition. On the other hand, the automatic conveying and discharging structure reduces the frequency of manual handling and operation, reducing repetitive work such as manual cleaning of solidified blocks, dredging of the material conveying pipe 1505 or checking the repair material condition.

[0028] Please refer to the attached Figure 9 - attached Figure 11The folding mechanism 21 comprises an L-shaped plate 2101 fixedly connected to the outside of the connecting plate 19, and a pull rod 2102 slidingly connected to the inside of the L-shaped plate 2101 on both sides, a protrusion 2103 fixedly connected to the bottom of the pull rod 2102, a fixing block 2104 fixedly connected to the middle of the pull rod 2102, a spring 2105 sleeved on the middle of the pull rod 2102, and a clamping hole 22 formed in the outside of the connecting plate 19, and the pull rod 2102 is inserted into the clamping hole 22, so that the position of the connecting plate 19 is fixed.

[0029] Specifically, when the repairing device needs to be moved, first, the protrusion 2103 is pulled, and the movement of the protrusion 2103 drives the pull rod 2102 fixedly connected to the inside of the protrusion 2103 to move in the corresponding direction, and the movement of the pull rod 2102 further drives the fixing block 2104 fixedly connected to the middle of the pull rod 2102 to move, and in the process of being connected with the pull rod 2102, the fixing block 2104 applies pressure to the spring 2105 sleeved on the outside of the pull rod 2102, so that the spring 2105 is deformed and generates a certain elastic reaction force, and the deformation of the spring 2105 is a key part of folding, which provides restoring force, so that the device can automatically return to the original position after the folding or unfolding operation is completed, and the situation of being stuck or not completely folded due to improper human operation is avoided. Through this process, the pull rod 2102 is separated from the clamping hole 22, so that subsequent operation is facilitated, and then the operator can fold the connecting plate 19 and the handle 20 according to the designed folding mode, so as to reduce the overall size of the equipment, the connection between the connecting plate 19 and the handle 20 is designed flexibly, and the connecting plate 19 and the handle 20 can be conveniently folded according to the use requirement, the folded equipment has a significantly reduced size, is convenient to move and store, occupies less space, and can be better placed during transportation, and after the operation of the first pull rod 2102 is completed, the operator repeats the same steps to pull the other pull rod 2102, and when the connecting plate 19 and the handle 20 are folded, the other pull rod 2102 is released, and the reaction force of the spring 2105 automatically makes the other pull rod 2102 reinserted into the clamping hole 22 formed in the inside of the connecting plate 19, so as to fix the connecting plate 19. Through this design, the folding and fixing process is not only efficient and convenient, but also can ensure that the equipment is firmly kept in the folded state after being folded, and the problems of loosening or incomplete folding due to improper operation are avoided.
