Multi-functional rotary plastering board

Abstract

The invention provides a multi-functional rotary plastering board which comprises a plastering board; a concave cavity is formed in the plastering board; a feeding opening is formed in the middle of the concave cavity; the inner surface of the concave cavity is a helicoidal surface a and a helicoidal surface b which are mutually connected; the rotating directions of the helicoidal surface a and the helicoidal surface b are opposite; a convex cavity outer edge is arranged on the edge of the concave cavity. The plastering board can not only treat a concave part and a convex part on a wall, but also continuously work, is reasonable in structure and can be provided with an automatic feeding system.

Description

technical field [0001] The invention belongs to the technical field of building construction tools, and in particular relates to a multifunctional rotary trowel. Background technique [0002] In the process of building construction, it is usually necessary to apply cement mortar or putty to the wall to make the wall smooth. However, the wall surface treatment such as wall plastering and putty is labor-intensive, the work process is cumbersome and the work efficiency is low. Although there are some wall wiping machines on the market, the wiping boards of both manual and wiping machines are basically flat wiping boards, but the flat wiping boards mainly face the following important problems, resulting in poor construction quality and low efficiency.

Problems solved by technology

[0002] In the process of building construction, it is usually necessary to apply cement mortar or putty to the wall to make the wall smooth. However, the wall surface treatment such as wall plastering and putty is labor-intensive, the work process is cumbersome and the work efficiency is low.

Although there are some wall plastering machines on the market, the plastering boards are basically flat plastering boards whether it is manual or wall plastering machines, but the flat plastering boards mainly face the following important problems, resulting in difficult construction quality and low efficiency

[0003] 1. The flat troweling board cannot be equipped with an automatic feeding system, resulting in an uncontinuous supply of materials for wall troweling work, so the troweling work is intermittent, the work efficiency is relatively low and the labor intensity of the workers is high

[0004] 2. Before the wall surface is smoothed, the material state of the wall surface is uneven, so the smoothing work needs to cut off the convex part of the wall surface and fill the pits on the wall surface. At present, it can only be handled manually Two types of work, extremely inefficient

[0005] 3. The working trajectory of the flat wiper board can only be a straight line, and it cannot achieve continuous smoothing work on the wall, so the efficiency is not high, and it is difficult to ensure the flatness of different straight line segments, and it is difficult to meet the flatness requirements of construction
