[0002] In construction projects, wall plastering can play a waterproof role.

[0003] Application No. 202321143431.4 discloses a wall plastering device for housing construction projects, in which cement in a mixing box is transported to a strip-shaped slurry outlet groove on an inclined frame through a mud pump. At this time, the mud overflows from the strip-shaped slurry outlet groove and slides downward on the inclined surface of the inclined frame by gravity until it slides into the gap between the plastering board and the wall. As the second motor drives the plastering board to move upward through a screw rod and a movable plate, the plastering board can also evenly spread the cement in the gap on the wall, thereby providing a buffer space for the cement and improving the plastering effect.

[0004] The plastering structure of the above application is limited by the support plate and the positioning frame, which makes it inconvenient to flexibly plaster different positions of the wall, especially for high-altitude operations.
