Description

Technical Field

[0001] The utility model relates to the technical field of road paving, and more specifically, to a road paving device. Background Art

[0002] Paving is a crucial step in road construction, impacting not only the lifespan and safety of roads but also the smooth flow of traffic and the city's image. With technological advancements and the acceleration of urbanization, traditional road paving methods are increasingly showing their limitations, such as low efficiency, difficulty in quality control, high labor costs, and significant environmental impact. Therefore, the development of a road paving device has become an urgent need within the industry.

[0003] After searching, a Chinese patent with announcement number CN220352572U discloses a municipal road paving device, which uses a delivery pump to extract cement mortar from a mixing tank and discharge the cement mortar evenly onto the road surface along multiple discharge pipes. The adjusting gear is driven by a lifting motor to rotate, which can drive the tooth plate and scraper to move up and down. The scraper is driven by the lifting motor to approach the road surface. As the moving wheel drives the bottom plate to move, the scraper can spread and flatten the fallen cement mortar, eliminating the need for workers to manually spread the cement mortar, thereby reducing the labor intensity of workers.

[0004] In the above-mentioned municipal road paving device, a lifting motor is used to control the lifting and lowering of the scraper. We know that general motors themselves do not have a locking function and need to be independently equipped with a brake device or an electromagnetic locking structure. Therefore, the above-mentioned method of only using a lifting motor to drive the scraper is not ideal in terms of stability during use. At the same time, in the above-mentioned method, cement mortar is evenly discharged from multiple discharge pipes to the road surface. Since there are gaps between the multiple discharge pipes, there are gaps between the discharged cement mortar. It is not easy for a separate scraper to scrape and fill these gaps with cement mortar, which affects the paving effect. Utility Model Content

[0013] Beneficial effects of the utility model:

[0014] 1. By setting up a lifting drive mechanism, the operator can adjust the height of the lifting plate according to needs during use, and then adjust the distance between the pyramid-shaped scraper and the ground, so as to better control the laying thickness of the cement mortar.
