[0002] After a road is put into use, various diseases will appear, among which cracks are the most common road diseases. Road cracks not only reduce the flatness, but also affect the appearance of the road. Failure to repair it in time will shorten the service life of the road. There are many reasons for road cracks: shrinkage of dry soil, weak foundation or road base, cracks in the road surface with poor paving joints, shrinkage of the asphalt layer, etc. When the road surface cracks, rainwater will penetrate through the cracks into the road base, subbase and even the roadbed, which will reduce the strength of the base and soil base, accelerate the destruction of the road, and shorten the service life of the road surface. Therefore, the repair and maintenance of road cracks is particularly important.

The utility model is provided with a group of support rods at one end below the base, and a first scraper and a rotating shaft are provided between the support rods.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device smoothes the slurry overflowing from the cracks through the first scraper, the height of the first scraper cannot be adjusted, and the first scraper is installed on the support rod through a rotating shaft, which makes it difficult for the first scraper to press tightly against the cracks in the ground, affecting the scraping effect of the overflowing slurry, resulting in poor flatness of the repaired road surface. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a road crack repairing device.

[0006] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a road crack repair device comprises a base, a plurality of supporting legs are fixed on the lower surface of the base, and a roller is arranged at the lower end of each supporting leg, a storage barrel is fixed on the upper surface of the base, a feeding hopper connected with the storage barrel is fixed on the upper surface of the storage barrel, a discharge pipe connected with the storage barrel is fixed on the lower surface of the storage barrel, and the discharge pipe passes through the base and is fixed, and a mounting plate is arranged at the bottom of the base, a U-shaped plate is fixed on the side of the lower surface of the mounting plate close to the discharge pipe, a pressure roller is rotatably connected to the inner wall of the U-shaped plate, and a scraper is arranged on the side of the lower surface of the mounting plate away from the pressure roller, and a lifting assembly for lifting the mounting plate is installed on the base, and the lifting assembly comprises a threaded rod that is penetrated and threadedly connected on the base, a rotating block fixed to the upper end of the threaded rod, and a guide rod that is penetrated and slidably connected on the base, the lower end of the threaded rod is rotatably connected to the upper surface of the mounting plate, and the lower end of the guide rod is fixed to the upper surface of the mounting plate.

[0007] By adopting the above technical solution, when it is necessary to repair road cracks, the staff fills the cracks with slurry through the feed pipe and rotates the threaded rod by the rotating block. Since the threaded rod is threadedly connected to the base, and the base is slidably connected to the guide rod, the mounting plate moves downward and the scraper and the pressure roller are pressed against the ground. The base is then pushed to make the pressure roller flatten the overflowed slurry, and then the scraper scrapes the flattened slurry, thereby enhancing the scraping effect of the overflowed slurry and improving the smoothness of the repaired road surface.

[0009] By adopting the above technical solution, the limit block is inserted into the limit hole, thereby fixing the scraper on the mounting plate. When the scraper needs to be maintained and cleaned, the staff only needs to pull the limit block through the control block to make the limit block disengage from the limit hole and enter the receiving groove, thereby removing the scraper from the mounting plate, making it easier to clean the scraper.

[0010] Furthermore, a mounting groove is provided on a side wall of the mounting plate close to the control block, a spring is provided in the mounting groove, one end of the spring is fixed to the inner wall of the mounting groove, and the other end of the spring is fixed to the side wall of the control block.

[0011] By adopting the above technical solution and setting the spring, the control block keeps the limit block in the plugged state with the limit hole under the elastic force of the spring, thereby reducing the probability of the limit block being separated from the limit hole.

[0012] Furthermore, a yielding portion cooperating with the upper surface of the scraper is provided on the lower surface of the limit block.

[0013] By adopting the above technical solution, when installing the scraper, the limit block is squeezed into the receiving groove during the process of inserting the scraper upward into the plug-in groove, eliminating the tedious operation of the staff to manually pull the control block, which is conducive to the convenient installation of the scraper.

[0014] Furthermore, a rubber sheet is fixed to the top wall of the plug-in slot.

[0015] By adopting the above technical solution, the rubber sheet is made of rubber material, and the material is elastic, thereby reducing the wear between the plug-in slot and the scraper.

[0016] Furthermore, a rotation groove is provided on the inner wall of the U-shaped plate, a rotating shaft rotatably connected to the U-shaped plate is provided through the side wall of the U-shaped plate, one end of the rotating shaft is rotatably connected to the rotation groove, the pressure roller is sleeved on the rotating shaft and rotatably connected, a threaded groove is provided on the side wall of the U-shaped plate away from the rotation groove, and a limit cover is provided on the side wall of the U-shaped plate threadably connected to the threaded groove.

[0017] By adopting the above technical solution, when the pressure roller needs to be disassembled, the staff only needs to rotate the limit cover to disengage the limit cover from the threaded groove, and then remove the rotating shaft from the U-shaped plate, thereby disassembling the pressure roller, which is convenient for cleaning and maintenance of the pressure roller.

[0018] Furthermore, an anti-lost rope is fixed to the side wall of the U-shaped plate, and one end of the anti-lost rope away from the U-shaped plate is fixed to the side wall of the limiting cover.

[0019] By adopting the above technical solution, the probability of the limit cover being lost after being opened is reduced.

[0020] Furthermore, a push rod is fixed to the side wall of the base close to the mounting plate, a fan is fixed to the side wall of the base away from the push rod, and an air outlet hood is fixed to the air outlet of the fan.

[0021] By adopting the above technical solution, the staff pushes the base through the push rod, and the wind generated by the fan is blown out to the crack surface through the air outlet hood, reducing the probability of dust and impurities accumulating on the crack surface and affecting the crack repair.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In this application, when it is necessary to repair cracks in the road, the staff fills the cracks with slurry through the feeding pipe, and rotates the threaded rod through the rotating block. Since the threaded rod is threadedly connected to the base, and the base is slidably connected to the guide rod, the mounting plate moves downward, and the scraper and the pressure roller are pressed against the ground, and then the base is pushed to make the pressure roller flatten the overflowed slurry, and then the scraper scrapes the flattened slurry, which enhances the scraping effect of the overflowed slurry and improves the flatness of the repaired road surface;

[0024] 2. In this application, the limit block is inserted into the limit hole, so that the scraper is fixed on the mounting plate.
