Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a concrete leveling device. Background Art

[0002] Concrete refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. It is widely used in civil engineering. After the concrete is poured, workers are usually required to use a scraper to scrape the surface of the concrete to make it flat. However, the process of manually scraping the concrete with handheld tools requires workers to bend over frequently, which is labor-intensive. The compaction degree and flatness of the concrete cannot be guaranteed, thereby affecting the efficiency of the concrete surface flattening. Therefore, this solution provides a concrete leveling device. Utility Model Content

[0009] The utility model provides a concrete leveling device, which has the following beneficial effects:

[0010] In this solution, the concrete surface is initially flattened at the front frame by a flat plate. After the initial flattening, the concrete surface is secondarily flattened by a smoothing plate after the mobile trolley is displaced. Finally, the second telescopic motor drives the roller bracket and the roller in the rear frame to perform a final repeated rolling of the secondarily flattened concrete surface to ensure the compaction and flattening of the concrete after pouring. The entire process only requires manual handrails to push the mobile trolley, which saves manpower and is more efficient in leveling the concrete. BRIEF DESCRIPTION OF THE DRAWINGS
