[0002] Road paving refers to the paving of roads, including laying various materials such as asphalt, cement, etc. to build a flat and solid road surface. It is an important part of road construction, involving laying various materials on the road surface to form a flat, wear-resistant and non-slip road surface. Such a road surface can not only ensure the smooth driving of vehicles, but also withstand the heavy pressure of vehicles and the influence of the natural environment. When paving roads, in order to quickly and efficiently lay materials on the roadbed, a paver is usually used. A paver is a specialized road paving equipment, mainly used for paving operations in roads, airports, squares and other occasions. The use of a paver can greatly reduce the amount of manual labor, reduce the number of workers, improve construction efficiency, speed up construction progress, and at the same time ensure the accuracy, density and flatness of asphalt concrete paving.

[0003] When a road is paved by a road paver, it is usually necessary to first lay the material on the road surface and roll the laid material to achieve compaction and leveling of the material. Since the material thickness may be different in different areas when the material is laid, the road surface may be uneven. In the prior art, the material cannot be well flattened before being compacted, which reduces the uniformity of paving, making it inconvenient for the rolling wheel to roll well, which is not conducive to improving the efficiency and effect of rolling, and thus making it inconvenient to complete the paving work quickly and efficiently.

[0024] A scraping mechanism is provided on the surface of the mobile frame 1, and the scraping mechanism includes a support plate 2, which is fixedly connected to the upper surface of the mobile frame 1, and a forward and reverse screw 21 is movably connected to the inner side of the support plate 2, and a first motor 22 is fixedly installed on the surface of the support plate 2, and a moving block 23 is threadedly connected to the surface of the forward and reverse screw 21, and a movable rod 24 is movably connected to the surface of the moving block 23, and a connecting plate 25 is movably connected to the bottom end of the movable rod 24, and a fixed rod 26 is fixedly connected to the bottom end of the connecting plate 25, and a scraping assembly 27 is fixedly connected to the bottom end of the fixed rod 26, and a through groove 210 is provided on the inner side of the mobile frame 1.

The operation of the first motor 22 drives the forward and reverse screws 21 to rotate. The moving block 23 will move horizontally under the action of the forward and reverse screws 21, and then the movable rod 24 will move through the rotating shaft under the action of the moving block 23. The connecting plate 25 is limited by the limit block 28 and the limit groove 29, and will stably move vertically under the action of the movable rod 24, so that the limit block 28 slides on the surface of the limit groove 29, so that the fixed rod 26 will drive the scraping assembly 27 to move vertically under the action of the connecting plate 25, so that the height of the scraping assembly 27 can be adjusted, so that the scraping assembly 27 can scrape the material at different heights. At the same time, the material can be pressed down by the continuous downward movement of the scraping assembly 27, which can better assist in compacting the material.
