[0024] Specifically, when using the asphalt pavement repair device, first add the asphalt and the filler into the charging bin 9, and then the asphalt and the filler enter the heating barrel 8. At this time, start the heating barrel 8. After the asphalt and the filler are melted, start the motor 3. The motor 3 drives the gear 4 to rotate, and then the gear 4 drives the gear 2 5 to rotate. Finally, the gear 2 5 is driven by the force to drive the stirring rod 7 to move. The movement of the stirring rod can promote the flow of the asphalt and the filler, ensuring that the asphalt and the filler form a good circulation in the stirring barrel, thereby achieving uniform mixing and temperature balance of the asphalt and the filler, improving the quality of the asphalt repair material, and finally the asphalt can be injected into the position to be repaired through the discharge nozzle 21.

[0025] Reference Figure 1 - Figure 3The lifting assembly includes a cylinder 11 and a lifting block 12, the output end of the cylinder 11 is fixedly connected to the top of the lifting block 12, the outer wall of the cylinder 11 is fixedly connected to the inside of the casing 1, and the outer wall of the lifting block 12 is slidably connected to the inside of the casing 1;

[0026] Specifically, when the asphalt pavement repair device needs to be used to vibrate and compact the road surface, first start the cylinder 11, and the cylinder 11 will drive the lifting block 12 to descend until it reaches the position where vibration compaction is required. When the vibration mechanism is not in use, the cylinder 11 can be started to contract, and the cylinder 11 will drive the lifting block 12 to rise to facilitate the movement of the repair device.

[0027] Reference Figure 1 - Figure 3 , wheels 10 are rotatably connected to both sides of the outer wall of the casing 1, a motor 2 13 is fixedly connected inside the lifting block 12, a disc 14 is fixedly connected to the output end of the motor 2 13, a rotating block 15 is rotatably connected to the bottom of the disc 14, a rotating shaft 16 is rotatably connected to the bottom of the rotating block 15, a transmission rod 17 is fixedly connected to the outer wall of the rotating shaft 16, a slider 18 is rotatably connected to the bottom of the lower rotating block 15, a connecting column 23 is fixedly connected inside the lifting block 12, a fixed block 24 is fixedly connected to the bottom of the connecting column 23, and the bottom of the fixed block 24 is fixedly connected to the lifting block 12, a screw rod 19 is threadedly connected inside the slider 18, one end of the screw rod 19 is rotatably connected to the connecting block 22, a motor 3 25 is fixedly connected inside the connecting block 22, the output end of the motor 3 25 is fixedly connected to the other end of the screw rod 19, a slide groove 20 is opened inside the connecting block 22, the outer wall of the slider 18 is slidably connected inside the slide groove 20, and the inner wall of the connecting block 22 is slidably connected to the outer wall of the connecting column 23;

[0028] Specifically, when it is necessary to use the asphalt pavement repair device to vibrate and compact the pavement, after lowering the lifting block 12, start the motor 2 13, and the motor 2 13 drives the disc 14 to rotate, and the rotation of the disc 14 drives the rotating block 15 and the rotating shaft 16 to move. The rotating block 15 will rotate in the horizontal direction, and the rotating shaft 16 will rotate in the vertical direction. Then the rotating shaft 16 drives the slider 18 to move through the transmission rod 17. The slider 18 also has a rotating block 15 and a rotating shaft 16, so the transmission rod 17 can transmit the power of the motor 2 13 to the slider 18. Finally, the slider 18 drives the connecting block 22 to reciprocate up and down to vibrate and compact the repaired pavement, so that the repair material is more closely combined with the surrounding pavement, and the repair effect is more uniform and stable.

[0029] Working principle: When using the asphalt pavement repair device, first add asphalt and other fillers into the charging bin 9, the asphalt and other fillers pass through the charging bin 9 and enter the heating barrel 8, and then start the heating barrel 8 to heat the asphalt and other fillers. When the asphalt and other fillers are melted, start the motor 3. Driven by the motor 3, the gear 4 is forced to rotate, and then drives the gear 2 5 to rotate, and then the gear 2 5 drives the stirring rod 7 to stir the asphalt and other fillers to ensure that the asphalt is evenly distributed and fully mixed with the filler. After the heating and stirring are completed, the material is injected into the road repair site through the discharge nozzle 21, and then the cylinder 11 is started to control the lifting block 12 to descend, and then the motor 2 13 is started. The motor 2 13 drives the disc 14 to rotate, and then the transmission rod 17 is forced to drive the connecting block 22 to move, continuously rise to the highest point and then fall and hit the fixed block 24 to generate vibration. Through the vibration of this mechanism, bubbles and gaps in the asphalt can be effectively eliminated to ensure that the filling material is evenly fitted to the surrounding road surface.
