Technical Field

[0001] The utility model relates to the technical field of applicators, in particular to a lightweight plastering gypsum mortar applicator with adjustable thickness. Background Art

[0002] A light-weight plastering gypsum mortar applicator is a tool used to evenly apply light-weight plastering gypsum mortar to building surfaces such as walls and floor slabs. The design of this tool is to improve construction efficiency and ensure the uniformity of mortar application and the consistency of thickness. It usually has a working surface, which can be a flat plate, a roller or other shapes, adapted to different construction needs and surface conditions. Announcement No.: CN220414764U discloses a leveling device for light-weight plastering gypsum mortar construction, comprising: a driving mechanism and a plastering mechanism arranged on a mobile base, a lifting assembly is arranged on the mobile base, two support columns are symmetrically arranged on the top surface of the lifting assembly, and an assembly box is arranged on the two support columns; the driving mechanism comprises: a driving device arranged in the assembly box, the output end of the driving device is connected to the transmission shaft through a gear set, and transmission gears are symmetrically arranged at both ends of the transmission shaft, and the transmission gears are meshed and connected with the side surfaces of the support columns; the plastering mechanism comprises: an ash box arranged on one side of the assembly box, a discharge port is arranged at the bottom of the ash box, and a plastering plate is arranged at the lower part of the discharge port. After adjusting the position of the movable base, the supporting column is raised by the lifting assembly until the top of the telescopic frame is close to the ceiling wall. When the driving mechanism drives the assembly box to rise, it can ensure that the ash box and the plastering board can move stably in the vertical direction, thereby ensuring the flatness during plastering and improving the plastering quality. However, the above-mentioned utility model cannot adjust the distance between the scraper and the wall. The scraper with a fixed distance may lead to the use of too much mortar, because the mortar coating thickness cannot be adjusted according to actual needs, resulting in material waste, which needs to be improved.
