One-sided plastering unit for tight spaces

Abstract

The invention discloses a single-side plastering device for a narrow and small space. The single-side plastering device comprises a support frame capable of being supported on the at least two opposite inner walls of the narrow and small space and sliding up and down under pulling of external force, a hopper with the lower end inclined outwards is fixedly mounted on one side of the support frame,and the hopper is a box-shaped body with a discharging opening in the lower end; a flexible concrete conveying pipe is arranged at the upper end of the hopper, the upper end of the flexible concrete conveying pipe communicates with a blender, and the lower end of the flexible concrete conveying pipe extends into the hopper; an ash shovel is mounted at the lower end of the hopper, the ash shovel isin a shovel shape and is composed of a shovel plate and baffles arranged on the two sides of the shovel plate, the upper end of the shovel plate is mounted on the inner side of the discharging opening of the hopper, and the lower end of the shovel plate is inclined outwards; concrete enters into the flexible concrete conveying pipe through the blender, flows to the hopper under the action of gravity of the concrete, and then evenly flows to the ash shovel through the discharging opening of the hopper, and plastering is conducted on the inner wall of a gas duct or the inner wall of an air shaft through the ash shovel.

Description

technical field [0001] The invention relates to a plastering device, in particular to a single-side plastering device for narrow spaces. Background technique [0002] In the process of house construction, it is necessary to plaster the flue, air shaft, wall and other places to effectively protect the surface of the wall, flue, air shaft, etc., and prevent the surface of each position from sagging, The phenomenon of falling off and cracking. At present, plastering is mainly carried out manually, which has the phenomenon of low construction efficiency and unguaranteed construction quality. In order to solve this problem, there have been many automatic devices for plastering walls, but the above-mentioned devices are large in size and can only be used for plastering walls, and cannot be applied to flues and air shafts in narrow spaces. Ash. [0003] Based on the above reasons, the applicant intends to design a device that is small in size, easy to operate, and can be applied...
