Description

Technical Field

[0001] The present application relates to the field of wall construction, and in particular to a wall plastering and leveling device. Background Technique

[0002] Wall plastering refers to the surface layer project of applying cement mortar, mixed mortar, and lime mortar on the wall. The indoor and outdoor wall plastering work is a task after the completion of the building structure construction. Scientific plastering work can play functions such as moisture-proof, weathering-proof, and heat-insulation, avoiding the erosion of the building wall by wind, rain, snow, etc. The concrete wall surface constructed by large formwork is smooth and flat, but at the joints of vertical and horizontal walls, the joints between upper and lower floors of stairwells, door and window openings and other parts of the wall constructed by large formwork need to be plastered and straightened;

[0003] In the wall plastering and leveling operation, the traditional method mainly relies on the manual operation and experience judgment of workers, using tools such as trowels and scrapers for plastering and leveling. This method not only has low efficiency, but also the quality is difficult to guarantee, and problems such as uneven wall surface and uneven plastering thickness are likely to occur. In addition, manual operation has high requirements for workers' skills and high labor intensity. Long-term work is likely to cause workers' fatigue and further affect the work quality;

[0004] Regarding the above-related technologies, the inventor believes that the wall plastering and leveling device has the defect that it is difficult to complete the wall plastering and leveling with high efficiency and high quality;

[0005] The above information disclosed in this background technique is only used to increase the understanding of the background technique of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

Detailed Description of the Invention

[0019] The following further describes the present application in detail with reference to the attached Figures 1-3 drawings.

[0020] An embodiment of the present application discloses a wall plastering and leveling device. Referring to Figure 1 , a wall plastering and leveling device includes a plate-shaped base 1, which enables the entire device to be stably supported and operated through the base 1, and a plurality of rollers 2 are rotatably connected to the lower surface of the base 1 so as to move the device to a designated location at any time. And on the lower surface of the base 1, studs 9 are threadedly connected through the sides of the plurality of rollers 2, and on the lower surfaces of the plurality of studs 9, block-shaped positioning blocks 10 are fixedly connected. Nuts 11 are threadedly connected to the outer surfaces of the plurality of studs 9, and the plurality of nuts 11 are all in close contact with the upper surface of the base 1. So that after the device is moved to a designated location, the positioning block 10 is pressed tightly against the ground by rotating the stud 9, and then the nut 11 is screwed downward on the outer surface of the stud 9 so that its lower surface is in close contact with the upper surface of the base 1, thereby stably fixing the device. Secondly, two rectangular parallelepiped-shaped alignment strips 3 are slidably connected to the upper surface of the base 1, and scale lines are provided on the surfaces of the alignment strips 3. Before plastering, by sliding the two alignment strips 3 so that the two alignment strips 3 slide out equal distances, the front ends of the alignment strips 3 are in close contact with the wall surface, so as to adjust the distances between the spraying plate 5, the scraping plate 6 and the wall surface, and further adapt to the plastering requirements of different walls;

[0021] At the same time, a rectangular parallelepiped-shaped support column 4 is fixedly connected to the upper surface of the base 1. A plate-shaped spraying plate 5 and a plate-shaped scraping plate 6 are slidably connected to the side surface of the support column 4. A plurality of nozzles 7 are fixedly connected to the side surface of the spraying plate 5. And a rectangular parallelepiped-shaped mortar chamber 8 is fixedly connected to the side of the support column 4 on the upper surface of the base 1. A delivery pipe is fixedly connected to the side surface of the mortar chamber 8, and the other end of the delivery pipe is fixedly connected to the side surface of the spraying plate 5. So that during the upward sliding process of the spraying plate 5 and the scraping plate 6, the mortar is sprayed onto the wall surface through the nozzles 7, and at the same time, the mortar is leveled by the scraping plate 6, thereby improving the plastering and leveling efficiency and quality, and reducing the labor intensity.

[0022] Referring to Figure 2 , two square groove-shaped second chutes 16 are opened on the upper surface of the base 1, and second screws 17 are rotatably connected to the inner walls of the two second chutes 16. The outer surfaces of the two second screws 17 and the two alignment strips 3 are threadedly connected through ball screws. So that by a worker rotating the second screw 17, the alignment strip 3 is driven to slide on the upper surface of the base 1 under the action of the ball screw. By observing the scale lines, the distances that the two alignment strips 3 slide out are the same, so that the horizontal distances between the left and right sides of the scraping plate 6 and the wall surface are equal, so as to improve the flatness of the mortar leveling.

[0023] Referring to Figure 1and Figure 3 On the side surface of the support column 4, a first chute 12 in the shape of a T-shaped groove is formed. A slider 13 in the shape of a T-shaped block is slidably connected to the inner wall of the first chute 12. A spraying board 5 in the shape of a plate is fixedly connected to the side surface of the slider 13. A connecting block 14 in the shape of a cuboid is fixedly connected to the side surface of the slider 13 below the spraying board 5. A scraping board 6 is fixedly connected to the side surface of the connecting block 14. A first screw rod 15 is rotatably connected to the inner wall of the first chute 12, and one end of the first screw rod 15 penetrates through the support column 4 to its upper surface and is fixedly connected to the output end of the motor. The outer surface of the first screw rod 15 is threadedly engaged with the slider 13 through a ball screw. Thus, by driving the first screw rod 15 to rotate by the motor, the slider 13 is driven to slide up and down under the action of the ball screw, thereby driving the spraying board 5 and the scraping board 6 to slide up and down, and then the plastering and leveling of the wall surface are completed with high efficiency and high quality.

[0024] The implementation principle of a wall plastering and leveling device according to an embodiment of the present application is as follows: The device is moved to a designated location through a plurality of rollers 2. Subsequently, the stud 9 is rotated to press the positioning block 10 tightly against the ground, and then the nut 11 is screwed downward on the outer surface of the stud 9 so that its lower surface is closely attached to the base 1, thereby stably fixing the device. Secondly, the staff rotates the second screw rod 17, and thus the alignment strip 3 is driven to slide on the upper surface of the base 1 under the action of the ball screw, so that the front end of the alignment strip 3 is closely attached to the wall surface, thereby adjusting the distance between the spraying board 5, the scraping board 6 and the wall surface to adapt to the plastering requirements of different wall surfaces. At the same time, the two alignment strips 3 slide out equal distances, so that the horizontal distances between the left and right sides of the scraping board 6 and the wall surface are equal, so as to improve the flatness of the mortar leveling. When plastering, the motor drives the first screw rod 15 to rotate, and thus the slider 13 is driven to slide up and down under the action of the ball screw, thereby driving the spraying board 5 and the scraping board 6 to slide up and down. In the process of the spraying board 5 and the scraping board 6 sliding upward, the mortar is sprayed onto the wall surface through the nozzle 7, and at the same time, the mortar is leveled by the scraping board 6, thereby improving the plastering and leveling efficiency and reducing the labor intensity, and then the plastering and leveling of the wall surface are completed with high efficiency and high quality.
