In order to restore the flatness and structural performance of the asphalt pavement, ensure the safe, comfortable and efficient driving of vehicles, and extend the service life of the road, it is necessary to repair and level the asphalt pavement.

[0003] Existing asphalt pavement repair and leveling methods generally rely on manual filling of potholes. Manual operation is inefficient, and the cleaning, filling, and compaction steps are cumbersome and time-consuming. Large-scale repairs are slow, seriously impacting traffic. Quality assurance is difficult, filling volume control is inaccurate, and compaction is insufficient. The road surface is prone to re-damage after repair, requiring repeated repairs. The labor intensity is high, and workers work long hours in harsh environments, easily fatigued, affecting work efficiency and health. Moreover, labor costs are constantly rising, and the large amount of manpower invested increases repair costs. At the same time, manual work on the road carries high safety risks and is prone to accidents, threatening workers' lives. Therefore, we propose an asphalt pavement repair and leveling device and method. Summary of the Invention

[0012] An operating method for repairing and leveling an asphalt pavement comprises the following steps: In step one, the asphalt pavement repair and leveling device is moved to the asphalt pavement to be repaired. The first asphalt pump is first activated. The first asphalt pump draws asphalt from the storage box through the pumping end and first pumping pipe on one side, then discharges the asphalt through the feeding end and first feeding pipe on the other side, and then discharges it through the discharge pipe, filling the asphalt pavement to be repaired. After filling, the first motor in the top chassis on one side of the hollow plate is activated. The first motor drives the driving gear through the first main shaft, which in turn drives the meshing driven gear, thereby rotating the stud. Because the bottom of the stud extends into the threaded groove at the top center of the telescopic plate and is threadedly connected to the inner wall, the rotation of the stud causes the telescopic plate to slide downward along the inner wall of the hollow plate under the sliding cooperation of the first slider and the first chute, thereby adjusting the height of the shovel box. The carrier is then moved, and the shovel box shovels excess asphalt into the shovel box.

[0013] Step 2: During the shoveling process, when the shoveling box is subjected to excess asphalt reaction force, the hollow plate will move along the slide rod under the action of external force. At this time, the spring sleeved on the surface of the slide rod will undergo elastic deformation, cushioning the hollow plate and the connected shoveling box and adjustment structure. At the same time, the damping rod will also play a damping and buffering role to reduce vibration and impact, and ensure the stability of the shoveling process.

[0014] Step three: Start the second motor, located in the center housing on the front surface of the front roller frame. This motor drives the first drive wheel via the second spindle, which in turn drives the second drive wheel via a chain. This in turn causes the second drive wheel, which is fixed to the front end of the leveling roller, to rotate together. As the carrier moves, the leveling roller flattens the asphalt after filling and leveling.

[0015] Step 4: Control the second asphalt pump. The second asphalt pump extracts the asphalt shoveled into the shoveling box through the extraction end and the second extraction pipe on one side, and then transports the asphalt to the storage box through the feeding end and the second feeding pipe on the other side for recycling so that it can be used again later.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The asphalt pavement repair and leveling device and method are designed with a discharge pipe, a storage box, a hollow plate, a telescopic plate, a stud, a threaded long groove, a shovel box, a first motor, a driving gear, a driven gear, a first asphalt pump, a first feeding pipe, a first extraction pipe, a second asphalt pump, a second feeding pipe, and a second extraction pipe. In the asphalt filling link, the first asphalt pump cooperates with the first extraction pipe and the first feeding pipe to discharge the asphalt in the storage box through the discharge pipe, thereby realizing rapid filling of the asphalt pavement to be repaired, avoiding the problems of low efficiency and uneven filling of manual filling, greatly shortening the filling time, and improving the overall repair efficiency. In terms of removing excess asphalt, the first motor drives the driving gear and the driven gear to drive the stud to rotate, thereby causing the telescopic plate to move along the inner wall of the hollow plate, and accurately adjusting the height of the shovel box, which can better adapt to the need to remove excess asphalt after repairing potholes of different depths. The utility model relates to a novel asphalt scraping machine, which is convenient for operation and reduces the labor intensity of manual shoveling. The second asphalt pump cooperates with the second extraction pipe and the second feeding pipe to draw the asphalt shoveled into the shoveling box back to the storage box for recycling and reuse, avoiding the waste of asphalt materials and reducing the repair cost. It conforms to the concept of resource conservation and environmental protection. The design of the groove, connecting frame, slide rod, spring, connecting block, second slide groove, second slider and damping rod, when the shoveling box is subjected to the reaction force of excess asphalt, the spring quickly undergoes elastic deformation, effectively absorbing and dispersing most of the impact force, reducing the instantaneous pressure on the equipment, and at the same time, the connecting block cooperates with the precise guidance of the second slide groove and the second slider, so that the damping rod can play a role in the predetermined direction, further slowing down the movement speed of the hollow plate through its damping characteristics, reducing vibration and shaking, and the two work together to provide efficient and reliable buffering for the shoveling process, ensuring the stability of the operation and the safety of the equipment.

[0027] An operating method for repairing and leveling an asphalt pavement comprises the following steps: In step one, the asphalt pavement repair and leveling device is moved to the asphalt pavement to be repaired. The first asphalt pump 27 is activated. The pump draws asphalt from the storage tank 5 through its pumping port and first pumping pipe 29 on one side. The asphalt is then discharged through the feed port and first feed pipe 28 on the other side, and then through the discharge pipe 4, filling the asphalt pavement to be repaired. After filling is complete, the first motor 24 within the top housing 23 of the hollow panel 7 is activated. The first motor 24 rotates the driving gear 25 via the first spindle, which in turn rotates the meshing driven gear 26, thereby rotating the stud 9. Because the bottom of the stud 9 extends through the threaded slot 12 at the top center of the telescopic panel 8 and is threadedly connected to the inner wall, the rotation of the stud 9 causes the telescopic panel 8 to slide downward along the inner wall of the hollow panel 7, assisted by the sliding engagement of the first slider 11 and the first chute 10. This adjusts the height of the shovel box 22, which then moves the carrier 1, and the shovel box 22 shovels excess asphalt into the shovel box 22.

[0028] Step 2. During the shoveling process, when the shoveling box 22 is subjected to excess asphalt reaction force, the hollow plate 7 will move along the slide rod 16 under the action of external force. At this time, the spring 17 sleeved on the surface of the slide rod 16 will undergo elastic deformation, cushioning the hollow plate 7 and the connected shoveling box 22 and the adjustment structure. At the same time, the damping rod 21 will also play a damping and buffering role to reduce vibration and impact, and ensure the stability of the shoveling process.

[0029] Step three: Start the second motor 36 located in the central housing 35 on the front surface of the front roller frame 33. This second motor 36 drives the first transmission wheel 37 via the second main shaft. The first transmission wheel 37 then drives the second transmission wheel 38 via the chain 39. This in turn causes the leveling roller 34, which is fixed to the front end of the second transmission wheel 38, to rotate together. As the carrier 1 moves, the leveling roller 34 flattens the asphalt that has been filled and leveled.

[0030] Step 4: Control the second asphalt pump 30. The second asphalt pump 30 extracts the asphalt shoveled into the shoveling box 22 through the extraction end and the second extraction pipe 32 on one side, and then transports the asphalt to the storage box 5 through the feeding end and the second feeding pipe 31 on the other side for recovery so that it can be used again later.

[0031] In summary, the asphalt pavement repair and leveling device and method, through the design of the discharge pipe 4, the storage box 5, the hollow plate 7, the telescopic plate 8, the stud 9, the threaded long groove 12, the shovel box 22, the first motor 24, the driving gear 25, the driven gear 26, the first asphalt pump 27, the first feeding pipe 28, the first extraction pipe 29, the second asphalt pump 30, the second feeding pipe 31 and the second extraction pipe 32, in the asphalt filling link, the first asphalt pump 27 cooperates with the first extraction pipe 29 and the first feeding pipe 2 8, can discharge the asphalt in the storage box 5 through the discharge pipe 4, realize the rapid filling of the asphalt road surface to be repaired, avoid the problems of low efficiency and uneven filling of manual filling, greatly shorten the filling time, and improve the overall repair efficiency. In terms of removing excess asphalt, the first motor 24 drives the driving gear 25 and the driven gear 26 to drive the stud 9 to rotate, thereby making the telescopic plate 8 move along the inner wall of the hollow plate 7, and accurately adjusting the height of the shoveling box 22, which can better adapt to the different depths of potholes after repair. The second asphalt pump 30 cooperates with the second extraction pipe 32 and the second feeding pipe 31 to draw the asphalt shoveled into the shoveling box 22 back to the storage box 5 for recycling, avoiding the waste of asphalt materials and reducing the repair cost, which is in line with the concept of resource conservation and environmental protection. The design of the groove 6, the connecting frame 15, the slide bar 16, the spring 17, the connecting block 18, the second slide 19, the second slider 20 and the damping rod 21 is that when the shoveling box 22 is subjected to the reaction force of excess asphalt, the spring 17 quickly undergoes elastic deformation, effectively absorbing and dispersing most of the impact force, reducing the instantaneous pressure on the equipment. At the same time, the connecting block 18 cooperates with the second slide 19 and the second slider 20 for precise guidance, so that the damping rod 21 can play its role in the predetermined direction, further slowing down the movement speed of the hollow plate through its damping characteristics, reducing vibration and shaking, and the two work together to provide efficient and reliable buffering for the shoveling process, ensuring the stability of the operation and the safety of the equipment.

7. A method for leveling an asphalt pavement using the asphalt pavement repair device according to any one of claims 1 to 6, characterized in that: The steps include: Step 1: Move the asphalt pavement repair and leveling device to the asphalt pavement to be repaired, start the first asphalt pump (27), and the first asphalt pump (27) extracts asphalt from the storage box (5) through the extraction end and the first extraction pipe (29) on one side of the asphalt pump (27), and then discharges the asphalt through the feeding end and the first feeding pipe (28) on the other side through the discharge pipe (4), thereby filling the asphalt pavement to be repaired. After the filling is completed, start the first motor (24) in the top chassis (23) on one side of the hollow plate (7), and the first motor (24) drives the driving gear (25) to rotate through the first main shaft. The driving gear (25) drives the driven gear (26) meshed with it to rotate, thereby rotating the stud (9). Since the bottom of the stud (9) penetrates into the threaded long groove (12) at the top center of the telescopic plate (8) and is threadedly connected to the inner wall, the rotation of the stud (9) causes the telescopic plate (8) to move downward along the inner wall of the hollow plate (7) under the sliding cooperation of the first slider (11) and the first slide groove (10), thereby adjusting the height of the shoveling box (22), and then the carrier (1) is moved, and the shoveling box (22) shovels the excess asphalt into the shoveling box (22); Step 2: During the shoveling process, when the shoveling box (22) is subjected to excess asphalt reaction force, the hollow plate (7) will move along the slide bar (16) under the action of the external force. At this time, the spring (17) sleeved on the surface of the slide bar (16) will undergo elastic deformation to cushion the hollow plate (7) and the connected shoveling box (22) and the adjustment structure. At the same time, the damping rod (21) will also play a damping and buffering role to reduce vibration and impact, thereby ensuring the stability of the shoveling process. Step 3: Start the second motor (36) located in the central housing (35) on the front surface of the front roller frame (33). The second motor (36) drives the first transmission wheel (37) to rotate through the second main shaft. The first transmission wheel (37) drives the second transmission wheel (38) to rotate through the chain (39), thereby rotating the first transmission wheel (37) and the second transmission wheel (38) fixed to the front end of the leveling roller (34). As the carrier (1) moves, the leveling roller (34) flattens the asphalt after filling and leveling. Step 4: Control the second asphalt pump (30). The second asphalt pump (30) extracts the asphalt shoveled into the shoveling box (22) through the extraction end and the second extraction pipe (32) on one side, and then transports the asphalt to the storage box (5) through the feeding end and the second feeding pipe (31) on the other side for recycling so that it can be used again later.
