Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a building wall plastering device. Background Art

[0002] In a construction project, after a building is completed, the surface of the wall needs to be smoothed with cement slurry and painted to increase the overall aesthetics of the building. At present, at the construction site, building wall plastering is still completed by manpower, which not only increases the work intensity, but also prolongs the construction time and increases the construction budget cost. Manual operation is very time-consuming. When the existing wall plastering machine smoothes the cement slurry on the wall, the cement slurry needs to be manually shoveled to the pressure plate of the wall plastering machine for use, which makes the cement slurry very labor-intensive when used, thereby reducing the practicality of the wall plastering machine.

[0003] Publication No. CN219298690U discloses a concrete wall plastering device, comprising a base and a wall plastering assembly installed on the base; the wall plastering assembly comprises a fixed rod fixedly connected to the upper surface of the base, a top plate fixedly connected to the upper surface of the fixed rod, and a support plate fixedly connected to the bottom end of the outer wall of the fixed rod, a threaded shaft is arranged between the top plate and the support plate, one end of the threaded shaft is rotatably connected to the lower surface of the top plate through a bearing, and a wall plastering assembly is arranged on this device, through which users can achieve rapid plastering of concrete, thereby avoiding the time-consuming and labor-intensive manual wall plastering and the waste caused by directly spraying slurry, and an adjustment assembly is added to this mechanism, which can adjust the angle of the scraper, so that the scraper can perform the wall plastering operation at a suitable angle, and the wall plastering effect is better.

[0004] However, the existing technology still has shortcomings:

[0005] 1. In the prior art, the concrete is stored in the hopper. During the process of the scraper rising, the concrete is gradually adsorbed on the wall from bottom to top, and the concrete is scraped flat by the scraper. This method avoids the time-consuming and labor-intensive manual wall plastering and the waste caused by directly spraying the slurry. However, the concrete cannot be mixed for the second time after being placed in the hopper, which makes it easy for the raw materials to be mixed unevenly, affecting the qualified rate of the wall plastering construction.

[0006] 2. In the prior art, during the process of the scraper rising, the concrete is gradually adsorbed on the wall from bottom to top, and the concrete is flattened by the scraper to fit the concrete to the wall. Although it can be added simply, the discharge speed of the concrete will change after adjusting the angle of the baffle, which affects the quality of the wall plastering. Utility Model Content
