[0002] The highway road surface will gradually develop dents and cracks due to long-term traffic and the ravages of wind and sun. If these dents and cracks are not dealt with in time, they will slowly expand and cause a large number of cracks in the road surface. Under the influence of natural factors such as driving loads and rain, potholes will gradually form. If the potholes are not repaired in time, it will bring traffic hazards to moving vehicles. The potholes will also gradually expand, making subsequent repairs difficult. Therefore, it is necessary to fill potholes and cracks in a timely manner.

When paving asphalt, asphalt is prone to turbulence, affecting the progress of road repair. After paving, the asphalt needs to be manually smoothed and compacted, which increases the work process of the staff and reduces the efficiency of pothole repair.

[0004] Therefore, there is a need for a pothole repair device for highway maintenance to solve the problems in the prior art that asphalt is prone to turbulence during asphalt paving and that asphalt needs to be manually leveled and compacted after paving. Utility Model Content

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the stirring mechanism 7 includes a rotating motor 71, a motor mounting seat 72 is fixedly connected to the outer surface of the rotating motor 71, the bottom surface of the motor mounting seat 72 is fixedly connected to the top surface of the stirring barrel 2, and a stirring shaft 73 is fixedly connected to the output end of the rotating motor 71. The stirring shaft 73 passes through the top of the stirring barrel 2, the stirring shaft 73 is rotatably connected to the stirring barrel 2, and a plurality of evenly distributed stirring rods 74 are fixedly connected to the outer surface of the stirring shaft 73.

[0022] Further as Figure 1 and Figure 2 As shown, it is worth specifically explaining that a threaded rod 8 is rotatably connected to the top surface of the base 1, a rotating handle 9 is fixedly connected to the top of the threaded rod 8, a movable plate 10 is threadedly penetrated by threads on the outer surface of the threaded rod 8, guide rods 11 are fixedly connected to both ends of the bottom surface of the movable plate 10, the guide rods 11 slide through the base 1, a connecting plate 12 is fixedly connected to the bottom end of the guide rod 11, a limit frame 13 is fixedly connected to the bottom surface of the connecting plate 12, an arc-shaped scraper 14 is fixedly connected to the bottom surface of the connecting plate 12, the height of the arc-shaped scraper 14 is the same as the height of the limit frame 13, the outer walls at both ends of the arc-shaped scraper 14 are fixedly connected to the inner walls at both ends of the limit frame 13, and the outer wall on one side of the arc-shaped scraper 14 is fixedly connected to the inner wall on the side corresponding to the limit frame 13.

[0023] Further as Figure 1 and Figure 2As shown, it is worth explaining in detail that two parallel fixed plates 15 are fixedly connected to the bottom surface of one side of the base 1, a rotating shaft 16 is rotatably connected between the two fixed plates 15, and a compacting wheel 17 is tightly sleeved on the outer surface of the rotating shaft 16.

[0024] This solution has the following working process: after the staff digs out and cleans the original asphalt in the potholes of the section to be repaired on the highway, they use this device to fill the potholes, open the movable cover 3 and put the asphalt into the mixing barrel 2, turn on the rotating motor 71 to drive the stirring rod 74 to rotate to prevent the asphalt from solidifying, move the device to the target area, turn the handle 9 to drive the threaded rod 8 to rotate, and the movable plate 10 moves downward under the action of the threaded rod 8, so that the limit frame 13 and the arc scraper 14 are in contact with the ground, turn on the asphalt pump 5, and the asphalt is sprayed out through the discharge pipe 6. The limit frame 13 prevents the asphalt from flowing to the area outside the pothole, and the asphalt filling is completed.

[0025] After the asphalt filling is completed, the asphalt pump 5 is turned off, and the worker pushes the device to smooth the filled asphalt under the action of the arc scraper 14. The device is repeatedly pushed, and the smoothed asphalt is repeatedly compacted by the compacting wheel 17 to complete the repair of the pothole.

[0026] According to the above working process, it can be known that: by setting up the stirring mechanism 7, the asphalt is stirred in the mixing barrel 2, and the fluidity of the asphalt can be effectively improved by using multiple stirring rods 74, so as to avoid its solidification during transportation, thereby ensuring the normal and orderly progress of the road repair work. By setting up the limit frame 13, the asphalt discharge is restricted to a fixed area, effectively avoiding the problem of easy turbulence of asphalt during asphalt paving.

[0027] By setting up the arc scraper 14, the asphalt after laying is smoothed, making the pothole part more flat and beautiful, which not only improves the efficiency of pothole repair, saves time and effort, but also enhances the repair quality. Through the action of the compacting wheel 17, the smoothed asphalt is repeatedly compacted, which is simple to operate and has a good compaction effect, thereby improving the work efficiency of the staff and effectively avoiding the problem of manual smoothing and compacting after asphalt laying.

[0028] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that two parallel fixed columns 18 are fixedly connected to the bottom surface of one side of the base 1, and rollers 19 are provided at the bottom ends of the fixed columns 18. A push handle 20 is fixedly connected to the top surface of one side of the base 1, and the push handle 20 is inclined to facilitate workers to push the device.

[0030] In summary: after the staff has dug out and cleaned the original asphalt in the potholes of the section to be repaired on the highway, they use the device to fill the potholes, pull the handle 22 to open the movable cover 3 and put the asphalt into the mixing barrel 2, turn on the rotating motor 71 to drive the stirring rod 74 to rotate, improve the fluidity of the asphalt and prevent the asphalt from solidifying, move the device to the target area through the push handle 20, turn the handle 9 to drive the threaded rod 8 to rotate, and the movable plate 10 moves downward under the action of the threaded rod 8, so that the limit frame 13 and the arc scraper 14 are in contact with the ground, turn on the asphalt pump 5, and the asphalt is sprayed out through the discharge pipe 6. Under the action of the limit frame 13, the asphalt is prevented from flowing to the area outside the pothole, and the asphalt filling is completed, which effectively avoids the problem of easy turbulence of asphalt during asphalt paving.

[0031] After the asphalt filling is completed, the asphalt pump 5 is turned off, and the staff pushes the device through the push handle 20. The filled asphalt is smoothed under the action of the arc scraper 14, making the pothole part smoother and more beautiful, improving the repair efficiency, and repeatedly pushing the device to repeatedly compact the smoothed asphalt through the compacting wheel 17 to complete the repair of the pothole. The operation is simple and effectively avoids the problem of manual smoothing and compacting after asphalt paving.
