Description

Technical Field

[0001] This utility model belongs to the field of building wall plastering construction technology, specifically relating to a smoothing device for indoor gypsum plastering. Background Technology

[0002] Plastering is a traditional construction method that involves applying mortar to the surfaces of walls, floors, and ceilings of buildings. Plastering is divided into interior and exterior plastering. Interior plastering typically refers to plastering of interior areas such as floors, ceilings, wainscoting, baseboards, and interior staircases, while exterior plastering refers to plastering of exterior areas such as exterior walls, awnings, balconies, and roofs. Interior plastering primarily protects walls, improves indoor hygiene, enhances light reflection, and beautifies the environment. In rooms susceptible to dampness or acid / alkali corrosion, it mainly protects walls, ceilings, and floors. Exterior plastering primarily protects walls from wind, rain, and snow erosion, improves the wall's moisture resistance, weathering resistance, and heat insulation, and enhances the wall's durability. It is also one of the measures for artistic treatment of various building surfaces.

[0003] The existing patent (CN111997311A) discloses a plastering device and its usage method for walls, which includes a brush holder and a slurry dispensing plate. However, it still requires workers to hold the device by hand to perform plastering operations, resulting in slow construction efficiency, high technical requirements, and the device being filled with plaster slurry, making it heavier than traditional plastering trowels and blades, hindering workers from performing plastering operations quickly and for extended periods. Therefore, a more labor-saving and efficient plastering device is needed. Utility Model Content

[0026] like Figures 1 to 4 As shown, this utility model includes a grout feeding mechanism and a plastering plate 16 disposed below the grout feeding mechanism. The base plate 1 is provided with a lifting mechanism and a translation mechanism for driving the plastering plate 16.

[0027] The lifting mechanism includes a first threaded rod 3 and a first guide rod 4 vertically arranged on the base plate 1. The tops of the first threaded rod 3 and the first guide rod 4 are connected by a top plate 7. A first lead screw nut 5 is sleeved on the first threaded rod 3, and a sleeve 6 is sleeved on the first guide rod 4.

[0028] The translation mechanism includes a second threaded rod 8 and a second guide rod 9 horizontally disposed between the first lead screw nut 5 and the sleeve 6. The second lead screw nut 10 is sleeved on the second threaded rod 8 and the second guide rod 9. A mounting seat 12 is provided on the upper part of the second lead screw nut 10, and the plastering board 16 is connected to the side of the second lead screw nut 10.

[0029] The slurry feeding mechanism includes a slurry outlet plate 13 disposed on one side of the mounting base 12, and a slurry feeding pipe 11 connected to the other side of the mounting base 12.

[0030] In actual use, by setting up a lifting mechanism, it is easy to drive the grout delivery mechanism to spray plaster grout onto the wall surface, and at the same time drive the plastering board 16 located below the grout delivery mechanism to smooth the wall surface from bottom to top, saving manpower and making it highly practical; by setting up a translation mechanism, it is easy to move the grout delivery mechanism and plastering board 16 to the adjacent wall surface after the current wall surface is plastered, so as to adapt to walls of different lengths and make it highly flexible.

[0031] In actual use, by setting the first guide rod 4, it is easy to guide the plastering board 16 to move vertically up and down, thereby ensuring that the plastering on the upper and lower parts of the wall is uniform and avoiding the problems of uneven force and large difference in plastering thickness that are easily caused by manual plastering.

[0032] In this embodiment, the plastering board 16 is a rectangular board in an inclined state, and one side of the plastering board 16 is fixed to the second lead screw nut 10 by a support rod 15; the side of the plastering board 16 away from the second lead screw nut 10 is lower than the side of the plastering board 16 close to the second lead screw nut 10.

[0033] It should be noted that the upper part of the plasterboard 16 is far from the wall, while the lower part of the plasterboard 16 is close to the wall, forming an inclined state, which facilitates the smoothing of the plaster slurry from bottom to top.

[0034] In this embodiment, the mounting base 12 has a threaded hole for supplying slurry to flow onto the slurry outlet plate 13, and the threaded hole is adapted to the slurry delivery pipe 11.

[0035] In this embodiment, the pulp outlet plate 13 is an inclined trapezoidal plate, and side plates 14 are provided on both sides of the pulp outlet plate 13; the side of the pulp outlet plate 13 away from the mounting base 12 is lower than the side of the pulp outlet plate 13 close to the mounting base 12, and the side of the pulp outlet plate 13 away from the mounting base 12 is longer than the side of the pulp outlet plate 13 close to the mounting base 12.

[0036] In actual use, the grouting pump is connected through the grout delivery pipe 11, which facilitates the extraction of gypsum grout. There is no need for manual picking up of gypsum grout and then smoothing the wall surface, resulting in high construction efficiency. By setting the grout outlet plate 13 to be a trapezoidal plate in an inclined state, the gypsum grout can flow out naturally. By setting the side plate 14, the gypsum grout on the grout outlet plate 13 can be prevented from flowing out from the side, thus avoiding waste of gypsum grout.

[0037] It should be noted that the side of the grout outlet board 13 closest to the wall is located above the plastering board 16, meaning that the gypsum grout flowing from the grout outlet board 13 can naturally flow onto the plastering board 16, which facilitates construction.

[0038] In this embodiment, casters 2 are provided at the four corners of the bottom of the base plate 1 for easy movement.

[0039] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
