Automatic sizing trowel

Abstract

Provided is an automatic sizing trowel which reduces the number of lime supply personnel, improves plastering efficiency, reduces labor intensity and improves working conditions. The automatic sizing trowel comprises a handle which is internally provided with a sizing agent transfer passage, a patter which smears a sizing agent on a wall, an electric switch arranged on the handle, and a trowel box assembly used to store sizing agent between the patter and the handle. The trowel box assembly comprises a box body and a sizing storage region in the box body. The sizing trowel can automatically size and the sizing storage region in the trowel box assembly is stored with moderate sizing agent. In operation, the patter is held by a hand, and is rotated to limiting positions on the left or on the right, the sizing agent stored in the sizing storage region is pressed by the patter and flows to a sizing outlet groove through sizing outlet holes and sizing through-holes, and then the sizing agent flows out from the sizing outlet groove and is smeared on the wall. Thus, a mason can easily smear the sizing agent on the wall by a single hand, so that working efficiency of the mason is greatly improved, and labor intensity of the mason is reduced.

Description

technical field [0001] The invention relates to tools used in construction engineering, in particular to a sizing trowel for plastering which can automatically supply slurry. Background technique [0002] With the development of my country's economic construction, the number of various industrial buildings, office buildings, and civil and commercial residential buildings is increasing, so that the amount of cement and concrete is increasing day by day. Therefore, the amount of cement plastering on walls and other surfaces is showing a rising trend. The labor intensity of the mason who is engaged in cement plastering is also increasing. [0003] At present, masons engaged in cement plastering are manual heavy manual labor. Commonly used tools are plasterboards and trowels. In the trough, the mason uses a trowel to pinch the cement slurry onto the gray board, and then holds the gray board with one hand, and with the other hand, applies the cement slurry on the gray board to th...

Problems solved by technology

Due to the heavy cement slurry, not only the arm holding the gray board is easily fatigued, but also every time the cement slurry on the gray board is used up, it is necessary to bend down again to pick up ash in the ash tank. If there are too many, it is easy to cause lumbar muscle strain. This endless repetitive operation not only seriously damages the health of the masons, but also affects the speed of plastering. At the same time, special personnel are required to supply materials, resulting in waste of manpower and low labor efficiency.
