The right side of the guide post 674 is fixed to the cover 671. The upper and lower sides of the shaft 678 respectively pass through the inner side of the two limit blocks 675 to ensure the stability of the rotation of the shaft 678.

[0027] The working principle of this utility model for removing wall plaster in construction projects is as follows:

[0028] First, move this design to the location where the wall plaster needs to be removed using the base 1, so that the design can be used;

[0029] Second, the user can control the folding and lifting main body 2 to change the height position of the scraping mechanism 6 in order to remove the wall plaster from different positions on the wall. After the height position is moved, the user controls the start of the drive main body 62. The drive main body 62 drives the first pulley group 63 to rotate inside the support block 64 so that the shift plate 65 drives the cover 671 to move to the left through the support plate 66, so that the cover 671 is fastened to the wall.

[0030] Third, the servo motor 676 is started. Under the action of the servo motor 676, the shaft 678 swings through the eccentric rotating plate 679 to drive the push rod 6710 to move back and forth in the inner side of the support frame 673. This causes the toothed block 67112 on the scraper 6711 to come into contact with the wall plaster and remove the wall plaster. The wall plaster scraped off during the wall plaster removal is sucked into the dust collection box 4 through the hose 5.

[0031] Fourth, during the process of removing wall plaster, the electric push rod 672 can be activated to move the support frame 673 to the left on the guide column 674, thereby causing the support frame 673 to drive the scraper 6711 to move closer to the wall, ensuring the removal effect of wall plaster of different thicknesses.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
