[0002] With the increase in traffic volume and the increase in vehicle load, cracks are prone to appear on the road surface. These cracks not only affect the appearance of the road, but more importantly, they reduce the safety and service life of the road and may further cause more serious road damage problems. If not repaired in time, these small cracks may develop into larger damage, resulting in higher maintenance costs and safety hazards.

[0003] Traditionally, the repair of pavement cracks usually relies on manual mixing of repair slurry on site and filling the mixed material into the cracks with simple tools. This method is particularly time-consuming and labor-intensive when facing large areas or multiple cracks, and the work efficiency is extremely low. It cannot meet the requirements of modern transportation engineering for rapid restoration of traffic. Due to manual operation, it is difficult to ensure the consistency and sufficiency of the mixing ratio each time, which directly affects the quality of the repair material and the stability of the final repair effect. In addition, dust or other pollutants may be generated during the on-site mixing process. If handled improperly, it will cause pollution to the surrounding environment and does not meet the current requirements of green construction. Therefore, it is necessary to design a pavement crack repair device for transportation engineering in view of the shortcomings of the existing technology. Utility Model Content

A mixing frame 6 is rotatably installed inside the mixing chamber 4 of the chassis 101, and the rotating shaft of the mixing frame 6 and the output shaft of the motor 5 The mud frame 1 is connected to the chassis 101, and a mud pump 7 is fixedly installed on the board surface of the mud machine frame 1. The inlet of the mud pump 7 passes through the chassis 101 through the feed pipe 81 and is connected to the bottom of the mixing bin 4. The outlet of the mud pump 7 is connected to a discharge pipe 8. The discharge pipe 8 passes through and extends downward to the bottom of the frame 1. The discharge pipe 8 is a hard pipe and its pipe mouth is downward toward the gap in the road surface to be repaired. A scraper for leveling the slurry is provided on the bottom surface of the board surface of the frame 1. The stirring frame 6 is driven by the motor 5 to evenly stir the repair slurry in the stirring bin 4, and the mixed mud is added to the gap in the road surface to be repaired by the mud pump 7. The whole device is pushed forward along the gap in the road surface, and the repair slurry added to the road surface gap is scraped flat by the scraper, so as to improve the efficiency and quality of the road surface gap repair.

[0021] like Figure 1 and Figure 2 As shown, the stirring frame 6 is detachably mounted on the output shaft of the motor 5 . The stirring frame 6 can select a suitable type of stirring blade according to the characteristics of different repair slurries, and the stirring frame 6 is convenient for cleaning and maintenance.

[0022] like Figure 3 and Figure 4As shown, the scraper includes a cylinder 9, a sliding plate 10, a guide rod 11 and a scraper plate 12. The cylinder 9 is fixedly mounted on the rear side of the frame 1, the piston rod of the cylinder 9 is vertically downward, the guide rod 11 is fixedly connected to the bottom surface of the chassis 101, the sliding plate 10 is slidably mounted on the guide rod 11, the sliding plate 10 is connected to the piston rod of the cylinder 9, an elastic member is provided at the end of the sliding plate 10 away from the cylinder 9, the scraper plate 12 is assembled on the elastic member of the sliding plate 10 through the mounting rod 121, the scraper plate 12 is used to scrape the repair slurry on the ground, the cylinder 9 drives the sliding plate 10 to move downward under the guidance of the guide rod 11, so that the sliding plate 10 drives the scraper plate 12 to move downward and contact the road surface, and under the action of the elastic member between the sliding plate 10 and the scraper plate 12, the scraper plate 12 can fit tightly on the road surface, thereby improving the quality of the scraped and repaired slurry.

[0023] like Figure 3 and Figure 4 As shown, the elastic member includes a connecting rod 13 and a spring 131. The sliding plate 10 is slidably connected to the connecting rod 13 at one end away from the cylinder 9. The mounting rod 121 of the scraper plate 12 is connected to the sliding rod. A spring 131 is arranged at the connecting rod 13 between the sliding plate 10 and the mounting rod 121. The sliding plate 10 presses the spring 131 downward until the scraper plate 12 contacts the repaired road surface. The spring 131 can continue to press the mounting rod 121 and the scraper plate 12 downward, so that the scraper plate 12 can stably fit the road surface for scraping. The scraper plate 12 is a rectangular corner plate as a whole, and the end of the scraper plate 12 has a curved edge, which can better fit the cracks in the road surface, ensuring that the repair material can evenly fill the cracks, thereby improving the repair efficiency and quality.

[0024] like Figure 1 As shown, it also includes a fixing plate 14 and a cover plate 15. The fixing plate 14 is fixedly provided on one side of the top opening of the mixing chamber 4 of the chassis 101. The cover plate 15 is hinged to the fixing plate 14 of the chassis 101 through a hinge 16. The cover plate 15 covers the top opening of the mixing chamber 4. Sealing gaskets are provided at the covering parts of the cover plate 15 and the mixing chamber 4 to prevent dust or other pollutants from being generated when the repair slurry is stirred in the mixing chamber 4 and causing pollution to the environment.

[0025] First, the operator opens the cover 15 on the chassis 101 and adds the required repair material into the mixing chamber 4 on the upper part of the chassis 101, and then closes the cover 15 and activates the motor 5. The motor 5 drives the stirring frame 6 connected thereto to rotate in the stirring chamber 4 to evenly stir the repair slurry. According to different repair requirements, the type of fan blades on the stirring frame 6 can be replaced to achieve the best stirring effect. This process ensures the uniformity and appropriate consistency of the repair slurry. Then the mixed repair slurry is extracted from the bottom of the mixing chamber 4 through the feed pipe 81 by the mud pump 7, and is directly transported to the cracks in the road surface to be repaired through the discharge pipe 8. The outlet of the discharge pipe 8 faces downward and accurately injects the slurry into the cracks, reducing waste and environmental pollution. The entire repair device is manually pushed by the handle 2 to the cracks to be repaired. When repairing the road surface, as the entire device is continuously pushed forward, the cylinder 9 drives the sliding plate 10 to move downward along the fixed guide rod 11 until the scraper plate 12 fits against the ground. At this time, the sliding plate 10 that continues to move downward is pressed on the scraper plate 12 by the spring 131, so that the scraper plate 12 can always fit tightly against the repaired road surface under the action of the spring 131. At the same time, the end of the scraper plate 12 has a curved edge, which can better adapt to cracks of different shapes and sizes, thereby ensuring that the repair material can evenly fill the cracks and be scraped smoothly. This not only improves the repair efficiency but also ensures the repair quality, making the road surface smooth and durable. During the entire repair process, the cover plate 15 and the sealing gasket can prevent the dust generated when the repair slurry is stirred in the mixing bin 4 from polluting the environment, while also ensuring the cleanliness of the work site.
