[0002] Asphalt pavement has a smooth surface and is comfortable to drive on. It is widely used in municipal roads. However, during use, it is affected by vehicle rolling and natural erosion, which can cause cracks in the asphalt pavement. If not repaired in time, the cracks will continue to grow and spread as the vehicle load increases and natural erosion continues, which will affect the passage of vehicles and even cause traffic accidents in serious cases.

[0003] In the traditional process of repairing cracks in asphalt pavement, workers usually hold a caulking cylinder and point the end of the caulking cylinder against the crack in the pavement. When the end of the caulking cylinder moves along the crack, asphalt will flow into the crack from the end of the caulking cylinder to repair the crack in the pavement. After that, the asphalt in the crack is manually scraped flat using tools. The operation is cumbersome and the work efficiency is low. Therefore, a highway maintenance pavement caulking device is proposed to address the above problems. Utility Model Content

[0006] A scraping assembly is installed at the front end of the injection cylinder. The top of the asphalt injected into the cracks of the road surface is scraped flat by the scraping assembly. The scraping assembly includes a mounting ring, which is sleeved on the front end of the injection cylinder. Fixed pins are symmetrically installed on both sides of the mounting ring. Connecting plates are rotatably installed on the fixed pins on both sides. The ends of the connecting plates on both sides away from the fixed pins are fixedly connected to the scraper.

[0007] Preferably, a torsion spring is fixedly mounted on the fixing pin to reset the connecting plate.

[0008] Preferably, a through hole is opened in the middle of the scraper, and a protective tube is fixedly connected to the scraper and located outside the through hole. The size of the through hole and the protective tube is larger than the size of the injection head.

[0024] See also Figure 1-4 As shown, a road maintenance pavement caulking device comprises a caulking cylinder 1, the front end of which is fixedly connected to a tubular caulking head 2, and the rear end of which is connected to a mobile asphalt supply device via a hose;

[0025] A scraping assembly is installed at the front end of the injection cylinder 1. The top of the asphalt injected into the cracks of the road surface is scraped flat by the scraping assembly. The scraping assembly includes a mounting ring 3, which is sleeved on the front end of the injection cylinder 1. Fixed pins 4 are symmetrically installed on both sides of the mounting ring 3. Connecting plates 5 are rotatably installed on the fixed pins 4 on both sides. The ends of the connecting plates 5 on both sides away from the fixed pins 4 are fixedly connected to the scraper 6. When working, hold the injection cylinder 1, align the injection head 2 with the cracks of the road surface, and keep the injection cylinder 1 at a certain angle with the ground. At this time, the bottom of the scraper 6 is close to the road surface. The asphalt is discharged from the supply device, enters the inside of the injection cylinder 1 through the hose, and is finally discharged from the injection head 2 into the cracks in the road surface. The asphalt is continuously injected until the highest position of the top of the asphalt exceeds the road surface. The injection moves backward at the same time. At this time, the installation ring 3, the fixing pin 4, the connecting rod and the scraper 6 are driven to move by the injection cylinder 1. The scraper 6 moves along the road surface to scrape the top of the asphalt flat, so that the asphalt in the crack is kept flat with the road surface, and no manual scraping is required, thereby improving the efficiency of crack repair.

[0026] A torsion spring 10 is fixedly installed on the fixing pin 4 to reset the connecting plate 5. During operation, the connecting plate 5 and the scraper 6 are placed in the same straight line as the filling tube 1 through the torsion spring 10, and the connecting plate 5 and the scraper 6 are driven by the torsion spring 10 to rotate downward relative to each other, so that the scraper 6 can be stably attached to the ground.
