Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to a building plastering machine. Background Art

[0002] Plastering refers to applying cement mortar, mixed mortar, or lime mortar to the wall surface. Indoor and outdoor wall plastering is a job that is done after the building structure is completed. Scientific plastering can prevent moisture, weathering, and heat insulation, and prevent the building walls from being eroded by wind, rain, snow, etc.

[0003] During the plastering process, the sandblasting machine sprays the mixed concrete mortar on the wall, and then the plastering machine is used to smooth the sprayed wall. During the smoothing process, the plastering board of the plastering machine will apply a certain amount of pressure to the wall to make the concrete mortar more tightly adhere to the wall. In this process, since the concrete mortar on some wall surfaces is relatively thick, it will be squeezed onto the plastering board of the plastering machine. When these concrete mortars stay on the plastering board, it will not only increase the load of the plastering board moving up and down, but when the concrete mortar accumulates to a certain extent, it will also affect the plastering quality of the plastered wall. Usually, the staff will scrape off the concrete attached to the plastering board when the plastering machine stops and changes position. This work will increase the plastering work steps of the staff and reduce the plastering efficiency. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-Figure 3 As shown, the utility model provides a technical solution: a building plastering machine, comprising a machine body 1, a guide rod 2 is arranged on one side of the machine body 1, a slider 22 is slidably installed inside the guide rod 2, a mounting rod 23 is arranged on the slider 22, a supporting groove which matches the contour of the lower side of the plastering plate 3 is arranged on the mounting rod 23, a connecting through hole 302 is arranged on the plastering plate 3 for mounting the plastering plate 3 on the mounting rod 23 by bolts, and a connecting rod 24 is also arranged on the mounting rod 23, and the connecting rod 24 is used to connect with one end of the traction rope 21 and drive the plastering plate 3 to move upward;

[0021] The slider 22 is provided with a plastering plate 3, and a traction rope 21 is extended from the body 1 to pull the plastering plate 3 to move upward smoothly. An inclined groove 301 is provided in the middle of the plastering plate 3, and both ends of the inclined groove 301 are inclined downward. The plastering plate 3 is formed by integral stamping.

[0022] A horizontally placed mounting plate 32 is provided on one side of the plastering plate 3 away from the guide rod 2 , and a trowel plate 33 for contacting and pressing the wall surface is provided on the mounting plate 32 .

[0023] In the utility model, by setting an inclined groove 301 in the middle of the plastering plate 3, and making the two ends of the inclined groove 301 inclined downward, the concrete falling into the inclined groove 301 can flow out from the two ends of the inclined groove 301 along the inclined groove 301, so as to avoid the accumulation of concrete mortar on the plastering plate 3. While reducing the load of the plastering plate 3 moving upward, it can also reduce the working steps of the plastering workers, so that the working efficiency of the workers is higher.

[0024] Furthermore, a connecting piece 31 is provided on the end surface of the trowel plate 33 facing the mounting plate 32, a mounting through hole 3101 is provided on the connecting piece 31, and a matching through hole 3201 is provided on the mounting plate 32. The connecting piece 31 and the mounting plate 32 are mounted to each other by bolts.

[0025] Furthermore, the middle of the trowel plate 33 is vertically arranged, and the upper and lower ends of the trowel plate 33 are inclined toward the direction of the mounting plate 32 .

[0026] Among them, by tilting the upper and lower ends of the trowel plate 33 toward the mounting plate 32, it is possible to prevent the trowel plate 33 from scratching the smoothed wall surface while following the up and down movement of the plastering plate 3. At the same time, it is also possible to reduce the amount of concrete mortar scratched off the wall surface, and to keep the concrete mortar of sufficient thickness attached to the wall surface.

[0027] Furthermore, it also includes a placing rack 4, which is used to place an ash hopper containing concrete. The placing rack 4 is provided with two groups, and the two groups of placing racks 4 are respectively located directly below the outlets on both sides of the inclined groove 301.

[0028] Furthermore, a support plate 41 is provided on the side of the guide rod 2 , and the placement rack 4 is installed on the support plate 41 .

[0029] Among them, by arranging the placement rack 4 on both sides of the guide rod 2, the concrete mortar falling from the outlets at both ends of the inclined groove 301 can be received, so as to avoid the concrete mortar from splashing when it falls to the ground. The splashed concrete is easy to fall and adhere to the wall surface, which will reduce the flatness of the wall surface.

[0030] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
