Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The utility model provides a road leveling machine, comprising the following structure:

[0033] like Figure 1 As shown, the road leveler includes a leveling module 3 for leveling the road surface and a driving module 1 for driving the leveling module 3 to move. The leveling module 3 is connected to the driving module 1 through a mounting structure 2. The driving module 1 can be a manual driving component or an electric driving component. The present embodiment is preferably a walking tractor. The walking tractor includes a handle 11 and a vehicle body 12. The operator can manually adjust the movement direction of the road leveler by operating the handle 11. Figure 2-4 As shown, the leveling module 3 includes a plurality of leveling rollers 31 for leveling the road surface, and a plurality of mounting portions 21 sequentially arranged along the axial direction of the leveling rollers 31 form a mounting structure 2, and two adjacent mounting portions 21 are detachably connected, and the detachable connection is preferably a bolt connection; the leveling roller 31 is connected to the driving module 1 through the mounting portion 21, and the leveling roller 31 and the mounting portion 21 are detachably connected through bolts to facilitate the replacement of the leveling roller 31. By disassembling the mounting portion 21 to increase or decrease the number of leveling rollers 31, the width of the leveling module 3 can be adjusted, thereby adjusting the leveling width of the road leveler according to actual road conditions to adapt to a variety of road environments and ensure the efficiency of the leveling operation.

[0034] In some embodiments, Figure 2 and Figure 4As shown, the leveling roller 31 includes a first leveling roller 311, which is arranged on the mounting portion 21; the axes of the plurality of first leveling rollers 311 are located on the same straight line, so that the leveling roller 31 forms a continuous and stable leveling plane when working, and can quickly and continuously process the road surface, thereby improving the continuity of construction. As a further improvement of this embodiment, the leveling roller 31 also includes a second leveling roller 312, which is arranged at the connection between two adjacent mounting portions 21. Specifically, one end of the second leveling roller 312 is connected to one mounting portion 21, and the other end is connected to the other mounting portion 21. The second leveling roller 312 is staggered with the first leveling roller 311, and the axes of the plurality of second leveling rollers 312 are located on the same straight line. By staggering the first leveling roller 311 and the second leveling roller 312, a denser leveling contact point can be formed during the leveling process, effectively covering the road surface details, and improving the uniformity and accuracy of the leveling.

[0035] In some embodiments, Figure 5 As shown, the leveling roller 31 is installed on the mounting structure 2 through a pulley bracket 32. The pulley bracket 32 ​​is connected to the mounting portion 21 and is provided with a roller groove 33 for accommodating the leveling roller 31. A wheel axle is provided in the middle of the leveling roller 31, and the two ends of the wheel axle are rotatably connected to the two side walls of the roller groove 33 respectively. The leveling roller 31 can rotate more stably during operation, reducing vibration and unnecessary wear, and improving the accuracy of the leveling operation and the service life of the leveling roller 31. As a further improvement of this embodiment, Figure 3 As shown, a cleaning scraper 34 for scraping off stains on the surface of the leveling roller 31 is provided in the roller groove 33, and a scraper angle 341 for scraping off foreign matter is provided on the cleaning scraper 34, and the scraper angle 341 abuts against the leveling roller 31. When in use, the leveling roller 31 rotates to drive foreign matter such as mud and cement slurry thereon to be automatically scraped off by the scraper angle 341, so that the leveling roller 31 can be kept clean during the leveling operation, and the leveling effect can be prevented from being reduced due to the accumulation of foreign matter.

[0036] In some embodiments, Figure 1 and Figure 3 As shown, the leveling module 3 also includes a plurality of leveling scrapers for leveling the road surface, and the leveling module is detachably connected to the mounting portion 21 by bolts. The leveling scrapers include a first leveling scraper 35 and a second leveling scraper 36 arranged in sequence along the moving direction of the leveling module 3; the leveling roller 31 is arranged between the first leveling scraper 35 and the second leveling scraper 36. When in use, the leveling scraper and the leveling roller 31 can work together, the leveling roller 31 compacts and levels the road surface, and the leveling scraper can further level and repair the road surface, achieving a more sophisticated leveling operation and significantly improving the flatness and smoothness of the road surface.

[0037] As a further improvement of the above embodiment, Figure 6As shown, the first leveling scraper 35 includes a shovel plate for shoveling up foreign objects and a receiving area 352 for accommodating foreign objects; the shovel plate includes a first inclined surface 351 for guiding foreign objects into the receiving area 352. When in use, the shovel plate can further level the road surface after the leveling roller 31 compacts the road surface, and the receiving area 352 can shovel up and collect excess cement debris to ensure the flatness and smoothness of the road surface. In order to prevent foreign objects from escaping and contaminating the road surface, it is preferred that a blocking bar 353 is provided on the shovel plate to prevent foreign objects from escaping from the receiving area 352.

[0038] As a further improvement of the above embodiment, Figure 7 As shown, the second leveling scraper 36 is provided with a second inclined surface 361 for reducing the resistance between the second leveling scraper 36 and foreign matter. When in use, the second inclined surface 361 is responsible for leveling the road surface. The design of the second inclined surface 361 enables the second leveling scraper to slide more smoothly on the road surface, ensuring the continuity of the leveling operation.

[0039] In some embodiments, Figure 1 As shown, the road leveling machine also includes a hydraulic part 4 for driving the mounting structure 2 to rise and fall. The hydraulic part 4 is connected to the driving module 1, and the mounting structure 2 is detachably connected to the hydraulic part 4 by bolts. When in use, the hydraulic part 4 can drive the mounting structure 2 to rise through the contraction of the hydraulic cylinder, so that the leveling module 3 is away from the ground, thereby improving the convenience of moving the equipment.
