Automatic wall-scraping device

Abstract

The invention discloses an automatic wall-scraping device, which can be used to scrape and plaster putty or mortar on a wall surface continuously and uniformly and comprises a bearing mounting plate (1), a driving internal toothed ring (2), a driven internal toothed ring (3), a toothed ring fixing wheel disc (4), a fly-cutter mounting wheel disc (5), a motor-driven gear (6), a direction adjusting planetary gear (7), a scraping and plastering fly cutter (8), a feeding fly cutter (9), a slurry box (10), a feeding pump (11), a suction pipe (12), a discharge pipe (13), a driving motor (14) and a carrier bearing body (15), wherein the feeding fly cutter and the scraping and plastering fly cutter are used for compressing the wall surface at an inclined angle; and when the wall-scraping device is rotated integrally, the feeding fly cutter is used for conveying and initially plastering putty in advance, and then the scraping and plastering fly cutter is used for plastering the putty uniformly and quickly; and in this manner, multiple fly cutters are operated continuously to scrape and plaster the putty on the wall surface uniformly at high speed. After the automatic wall-scraping device is mounted on an automatic bearing platform, the wall-scraping device can do the rectilinear motion along the wall surface, adjust the angle of the cutters, and perform feeding, scraping and plastering automatically, thereby realizing the full-automatic operation in the wall-scraping process.

Description

technical field [0001] The invention relates to a mechanical device, in particular to an automatic wall batching device for continuously and uniformly applying putty or mortar to a wall surface. Background technique [0002] In the building decoration process, after the building wall has been plastered with mortar, before spraying the wall paint or pasting the wallpaper, it is necessary to apply putty or lime mortar to the wall to make the wall smooth and smooth The beauty of the decoration. [0003] At present, the batch plastering of the wall is all done by hand. The plaster worker scoops up a small amount of putty with a manual trowel, presses it tightly on the wall, and slides it from bottom to top, so that the putty is evenly applied to the wall, and then repeats. Slide and knead several times to make the putty stick firmly to the wall. The thickness of one batch of application is relatively thin. After the putty is slightly dry, it is first polished to smooth the rou...
