DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and the following embodiments are used to illustrate the utility model.

[0024] As Figures 1 to 5 shown, a road surface pit filling device, including pit filling vehicle 1, pit filling vehicle 1 is fixedly installed with shell 9, shell 9 is fixedly installed with rotating shaft 12, rotating shaft 12 is rotatably installed with second rotating rod 11, and second rotating rod 11 is internally provided with straight slot 20, pit filling vehicle 1 is fixedly installed with base 6, base 6 is fixedly installed with stirring barrel 7, stirring barrel 7 is internally inserted with stirring shaft 4, one end of stirring shaft 4 is connected with motor 3, stirring shaft 4 is inserted into shell 9, the other end of stirring shaft 4 is fixedly installed with first rotating rod 10, and first rotating rod 10 is installed in straight slot 20, a plurality of threaded holes 15 are formed in second rotating rod 11, one threaded hole 15 is installed with bolt 13, the end of bolt 13 is connected with connecting block 14, connecting block 14 is internally inserted with spring pipe 16 and discharge pipe 19;

[0025] The pair of pull rods 23 are fixedly installed on the pit repairing vehicle 1, and the electric hydraulic rods 24 are installed at the ends of the pair of pull rods 23. The shaft sleeves 25 are connected to the ends of the electric hydraulic rods 24, and the rotating shafts 26 are fixedly connected in the shaft sleeves 25. The rollers 27 are rotatably connected to the rotating shafts 26. In the present arrangement, the pit repairing vehicle 1 can transport asphalt to the place to be repaired. Many transmission parts can be installed in the shell 9. The rotating shaft 12 can make the second rotating rod 11 rotate. The base 6 is used for supporting the stirring barrel 7, so that the stirring barrel 7 can be firmly installed on the pit repairing vehicle 1. The motor 3 can make the stirring shaft 4 rotate, so as to provide power for the stirring shaft. The stirring shaft 4 can drive the stirring blades 5 to rotate, so as to achieve the stirring effect. While stirring, the stirring shaft 4 can also drive the first rotating rod 10 to rotate. The first rotating rod 10 is installed in the straight groove 20, and can drive the second rotating rod 11 to swing around the rotating shaft 12. The plurality of threaded holes 15 can make the connecting block 14 installed at different positions. The installation at different positions can change the swing size of the discharge pipe 19. When the connecting block 14 is connected to the threaded hole 15 at the upper position, the swing distance of the discharge pipe 19 is small. Conversely, the swing distance of the discharge pipe 19 is large. The bolt 13 can make the connecting block 14 fixedly installed on the second rotating rod 11. The connecting block 14 is used for connecting the spring pipe 16 and the discharge pipe 19. The spring pipe 16 can make the asphalt in the stirring barrel 7 reach the discharge pipe 19. The spring pipe 16 is telescopic. When no pulling force is applied to the spring pipe 16, the spring pipe 16 can be retracted, so as to prevent the pipe from falling off. The discharge pipe 19 can transport asphalt to the place to be repaired. The pair of pull rods 23 are connected to the pit repairing vehicle 1, and are connected to the side wall of the shell 9. The pair of pull rods 23 can strengthen the fixation of the shell 9. The electric hydraulic rods 24 are installed at the ends of the pair of pull rods 23. The electric hydraulic rods 24 can make the rollers 27 move up and down. The shaft sleeves 25 are used for sleeving the rotating shafts 26. The rotating shafts 26 can ensure that the rollers 27 can rotate. The rollers 27 can press the asphalt to achieve the repairing effect.

[0026] As shown in the specific embodiment, the pit repairing vehicle 1 is fixedly installed with the burner 2. The burner 2 is connected with the injection pipe 21. The injection pipe 21 is connected to the stirring barrel 7. The upper portion of the stirring barrel 7 is provided with the feeding port 8. Figures 1 to 4 As shown in the specific embodiment, the pit repairing vehicle 1 is fixedly installed with the burner 2. The burner 2 is connected with the injection pipe 21. The injection pipe 21 is connected to the stirring barrel 7. The upper portion of the stirring barrel 7 is provided with the feeding port 8.

[0027] Figures 3 to 5 As shown in the specific embodiment, the pit repairing vehicle 1 is fixedly installed with the burner 2. The burner 2 is connected with the injection pipe 21. The injection pipe 21 is connected to the stirring barrel 7. The upper portion of the stirring barrel 7 is provided with the feeding port 8.

[0028] As shown in the specific embodiment, the pit repairing vehicle 1 is fixedly installed with the burner 2. The burner 2 is connected with the injection pipe 21. The injection pipe 21 is connected to the stirring barrel 7. The upper portion of the stirring barrel 7 is provided with the feeding port 8. Figures 3 to 4 ​As shown, a pump body 17 is connected to the end of the spring tube 16, and a connecting pipe 18 is connected to the side wall of the pump body 17. The end of the connecting pipe 18 is connected to the inside of the mixing tank 7. In this configuration, the pump body 17 can transport the asphalt in the mixing tank 7 to the discharge pipe 19 through the spring tube 16.

[0029] like Figures 2 to 4 As shown, the pothole repair vehicle 1 has a square groove 28 on its carriage. In this configuration, the square groove 28 is used to avoid the rotation of the discharge pipe 19, so that the asphalt can fall smoothly into the pothole.

[0030] like Figure 1 As shown, a cover plate 22 is installed on the housing 9. In this configuration, the cover plate 22 is used to close the housing 9, which can prevent the internal parts of the housing 9 from being exposed to the outside, and can increase the service life and reduce safety hazards.

[0031] The implementation principle of a road surface repair device in this embodiment is as follows: The operator injects asphalt into the mixing tank 7 through the inlet 8. Due to the operation of the motor 3, the mixing shaft 4 rotates, allowing the mixing blades 5 to agitate the asphalt. The spray pipe 21 transfers the heat generated by the burner 2 into the mixing tank 7 to prevent the asphalt from cooling. The electric hydraulic rod 24 lifts the roller 27 upwards, making it easier for the repair vehicle 1 to reach the location where the repair needs to be done. After reaching the required location, the electric hydraulic rod 24 moves the roller 27 downwards to the ground. The pump body 17 is turned on to transport the asphalt in the mixing tank 7 to the connecting pipe 18, and finally to the spring tube 16. The discharge pipe 19 then delivers the asphalt to the location where the repair needs to be done. Due to the rotation of the mixing shaft 4, the first rotating rod 10 will rotate synchronously. Since the second rotating rod 11 has a straight groove 20, the second rotating rod 11 swings around the rotating shaft 12 under the drive of the first rotating rod 10. Ultimately, the discharge pipe 19 can swing, making the asphalt discharge more even and preventing the asphalt from piling up and causing the roller 27 to be uneven. Since the second rotating rod 11 has several threaded holes 15, connecting the connecting block 14 to different threaded holes 15 can change the swing distance of the discharge pipe 19, making it suitable for pits of different sizes. Connecting the connecting block 14 to the threaded hole 15 at a higher position with the bolt 13 can make the swing distance of the discharge pipe 19 smaller, and vice versa. Therefore, the operator can open the cover plate 22 and connect the connecting block 14 to different positions with the bolt 13 to deal with different pits. The swing of the discharge pipe 19 can make the asphalt fall evenly into the pit. After there is enough asphalt, the pit repair vehicle 1 will slowly move forward. Then the roller 27 at the rear of the pit repair vehicle 1 can flatten the asphalt. In this way, the pit can be repaired as long as the pit repair vehicle 1 passes by, without the need for workers to spread it evenly, which can reduce the workload of the operator.
