Description

Technical Field

[0002] A concrete trowel, also known as a trowel, is a machine used to smooth concrete surfaces. It is widely used for adding slurry, smoothing, and finishing concrete surfaces in high-standard factories, warehouses, parking lots, plazas, airports, and frame buildings, making it the preferred tool for concrete construction.

[0003] Publication No. CN 116044128 A discloses a concrete floor smoothing robot. During the smoothing process, as the concrete in the center is smoothed to the surrounding area, the second motor rotates. Four auxiliary smoothing structures are installed around the main smoothing structure. This facilitates further smoothing of the concrete spread to the surrounding area by the main smoothing structure. The smoothing effect is good, but the patent still has the following problems in actual use:

[0004] Although the concrete floor smoothing robot can smooth the concrete floor, it cannot fill or scrape the concrete bumps or depressions during the smoothing process. Since the concrete contains a certain amount of aggregate, the aggregate cannot be roughly smoothed inside the concrete, which affects the smoothing effect of the concrete surface. It is necessary to manually fill the depressions or protrusions of the concrete, which affects the smoothing effect. At the same time, it is impossible to make accurate judgments when filling or removing aggregates, which increases the time for concrete smoothing and increases the labor intensity of workers.

[0005] Therefore, a ground leveling device for concrete construction is proposed to solve the above-mentioned problems. Summary of the Invention
