Technical Field
[0001] This utility model belongs to the field of highway maintenance technology, specifically a crack sealing device for highway maintenance. Background Technology
[0002] During long-term use, highways are highly susceptible to cracking due to various factors such as vehicle loads, temperature changes, and geological settlement. If these cracks are not addressed promptly, rainwater and snow can seep into the base layer, leading to softening of the subgrade, damage to the pavement structure, and ultimately, more serious defects such as potholes and alligator cracking. This not only significantly shortens the highway's lifespan but also poses a serious threat to driving safety. Therefore, timely and effective crack sealing is crucial for ensuring highway performance and extending its service life. Currently, commonly used crack sealing devices in highway maintenance mainly consist of a storage tank, a heating system, a delivery pipeline, and sealing nozzles. The working principle involves placing the sealing material (such as asphalt or sealant) into the storage tank, heating and melting the material through the heating system to give it a certain degree of fluidity, and then injecting the material into the crack through the sealing nozzles via the delivery pipeline to complete the crack repair.
[0003] However, existing crack sealing devices have a significant problem in practical use: when crack sealing operations are interrupted or the operation speed is slow, the material in the storage tank, due to the lack of continuous stirring, is prone to localized cooling or uneven heating during the heating process, leading to solidification and clumping. Once the material solidifies, its fluidity decreases significantly, making it difficult to smoothly pass through the delivery pipeline to the crack sealing nozzle, affecting the continuity and efficiency of the crack sealing operation. Moreover, the solidified or clumped material, after being injected into the crack, cannot adhere tightly to the crack wall, greatly reducing the quality of the repair and causing problems such as re-leakage, making it difficult to achieve the desired maintenance effect. In addition, the solidified material may also clog the delivery pipeline and crack sealing nozzle, increasing equipment maintenance costs and downtime, and causing many inconveniences to highway maintenance work.
[0004] Therefore, this utility model provides a crack sealing device for highway maintenance. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a crack sealing device for highway maintenance is proposed.

[0010] Preferably, the leveling component includes a second scraper and an inclined plate. The second scraper is fixedly installed on the bottom of the base plate near the discharge pipe. The two sides of the second scraper are fixedly installed with the inclined plate.

[0012] Preferably, the storage tank is made of stainless steel. In this design, the inner wall and surface of the stainless steel are relatively smooth, which allows the material to flow more smoothly on its inner wall and also makes the material less likely to stick.

Servo motor 52, cover plate 53, and discharge pipe 54. The storage tank 51 is fixedly installed on the top of the bracket 3. The bottom end of the storage tank 51 is fixedly installed with the servo motor 52. The top end of the storage tank 51 is rotatably installed with the cover plate 53. One side of the bottom of the storage tank 51 is connected to the discharge pipe 54. The discharge pipe 54 has a built-in solenoid valve for controlling the discharge amount. The stirring mechanism 6 includes a rotating shaft 61, a large spiral blade 62, and a small spiral blade 63. The rotating shaft 61 is rotatably installed on the inner wall of the storage tank 51. The output end of the servo motor 52 is fixedly installed with the rotating shaft 61. The side of the rotating shaft 61 closest to the servo motor 52 is connected to the large spiral blade 63. The spiral blade 62 is fixedly installed, and the middle part of the surface of the rotating shaft 61 is fixedly installed with the small spiral blade 63. The stirring assembly 7 includes a U-shaped frame 71 and a stirring rod 72. Several sets of U-shaped frames 71 are arranged in a ring and fixedly installed on the surface of the rotating shaft 61, located on the side where the large spiral blade 62 and the small spiral blade 63 are close to each other. The inner wall of the U-shaped frame 71 is fixedly installed with the stirring rod 72. The scraping mechanism 8 includes a fixed plate 81, a first scraper 82, and a stirring plate 83. Several sets of fixed plates 81 are arranged in a ring and fixedly installed on the surface of the rotating shaft 61 away from the large spiral blade 62. On one side, the side of the fixed plate 81 away from the rotating shaft 61 is fixedly installed with the first scraper 82, and the side of the first scraper 82 away from the fixed plate 81 is fixedly installed with the stirring plate 83. The leveling component 9 includes a second scraper 91 and an inclined plate 92. The second scraper 91 is fixedly installed on the bottom of the base plate 1 near the discharge pipe 54. Both sides of the second scraper 91 are fixedly installed with the inclined plate 92. The compaction component 10 includes a connecting frame 101 and a compaction roller 102. The connecting frame 101 is fixedly installed on the bottom of the base plate 1 away from the moving wheel 4. The inner wall of the connecting frame 101 is rotatably installed with the compaction roller 102. The storage tank 51 is made of stainless steel.
[0021] like Figures 1 to 3As shown, the combined use of the storage tank 51 and the cover plate 53 allows for better material storage and mixing. The servo motor 52 provides sufficient power for the rotation of the stirring mechanism 6. The discharge pipe 54 discharges material left and right, and the discharge amount is controlled by an internal solenoid valve. The combined use of the rotating shaft 61, the large spiral blade 62, and the small spiral blade 63 continuously stirs the material inside the storage tank 51 through rotation, while also continuously conveying the material upwards to prevent material accumulation at the bottom of the storage tank 51. The combined use of the U-shaped frame 71 and the stirring rod 72 stirs the material inside the storage tank 51, ensuring that the material does not clump or solidify, and also making the material heat more evenly. The fixed plate 81, the first scraper 82, and the stirring rod 72 are also included. The combined use of the rotating small plate 83 can continuously rotate and agitate the material while simultaneously scraping the inner wall of the storage tank 51 to prevent material from adhering to the inner wall and causing loss. It can also prevent the material from solidifying on the inner wall of the storage tank 51 and becoming difficult to clean. The combined use of the second scraper 91 and the inclined plate 92 can scrape the material discharged from the discharge pipe 54 to level it, so that the filled material can be kept flat with the road surface. It can also scrape the remaining material into the next gap for continuous filling. The combined use of the connecting frame 101 and the compaction roller 102 can compact and level the filled material, so that the repaired road surface can maintain a high quality. The stainless steel inner wall and surface are relatively smooth, which allows the material to flow more smoothly on its inner wall and also makes the material less likely to adhere.
[0022] Working Principle: During operation, the base plate 1 is first moved to the road surface. Then, the user opens the cover plate 53 and pours the repair material into the storage tank 51. The cover plate 53 is then closed, and the servo motor 52 is started, driving the rotating shaft 61 to rotate. The rotation of the rotating shaft 61 drives the large spiral blade 62 and the small spiral blade 63 to rotate, continuously agitating the material and conveying it towards the cover plate 53. Simultaneously, the rotation of the rotating shaft 61 drives the U-shaped frame 71 and the stirring rod 72 to rotate, continuously agitating the material, making it finer and more fluid. At the same time, the fixed plate 81 and the first scraper 82 rotate synchronously with the rotating shaft 61. The rotation of the fixed plate 81 and the first scraper 82 not only agitates the material but also scrapes away impurities from the storage tank. The material remaining on the inner wall of 51 is prevented from being wasted and difficult to clean. At the same time, the stirring plate 83 can rotate in conjunction with the small spiral blade 63 to stir the material and prevent it from solidifying. When moving to the section of road that needs repair, the user activates the solenoid valve built into the discharge pipe 54 and simultaneously starts the servo motor 52 to reverse it. As the rotating shaft 61 reverses, the large spiral blade 62 and the small spiral blade 63 will transport the material downwards, so that it can be discharged through the discharge pipe 54 and fall to the ground, and flow into the gap to repair the gap. As the base plate 1 continues to move, the second scraper 91 and the inclined plate 92 will push the excess material forward to fill other gaps under the route. When the filling material is about to run out, the solenoid valve needs to be activated again to discharge the material. After the repair is completed, the compaction roller 102 can compact the road surface after the repair to prevent the material from bulging.
