Description

Technical Field

[0001] The utility model relates to the technical field of plastering equipment, in particular to a multi-purpose plastering shovel. Background Art

[0002] Plastering and leveling are crucial steps in construction, especially ensuring the squareness and verticality of openings. The quality of plastering and leveling directly impacts the effectiveness of subsequent decorative projects, such as tiling, painting, and door and window installation. Traditional plastering and leveling typically involves multiple steps, including plastering, leveling, and finishing. Each step requires highly skilled workers and takes a long time. Improper handling can easily lead to uneven walls, cracking, bulging, and other quality issues, impacting both construction progress and the final result.

[0003] Currently, several technical solutions have been proposed and implemented in the field of plastering and leveling. Trowels and scrapers are the most common plastering and leveling tools. Trowels are used to evenly apply plaster material to the wall surface, while scrapers are used to scrape off excess material to ensure a smooth surface. This method relies on manual labor, significantly impacting the final result depending on the worker's skill level. It is also susceptible to human factors, such as instability caused by fatigue. Traditional plastering and leveling with scrapers requires workers to apply the work section by section, repeatedly measuring and adjusting the surface. This results in low overall efficiency, especially when working on complex or high walls. This is time-consuming and labor-intensive, and cannot meet the requirements of fast construction. Prolonged manual operation can easily lead to worker fatigue, which in turn affects accuracy. When fatigued, the force and angle of the scraper may become unstable, resulting in poor leveling results, uneven areas, and uneven thickness of the material. When working near wall edges, corners, or other narrow areas, the scraper's limited operating space makes it difficult to achieve ideal leveling results. These areas often require additional tools for finishing, adding complexity to the construction process.

[0004] How to solve the above technical problems is the subject faced by this utility model. Utility Model Content
