automatic sizing trowel

Abstract

The utility model relates to an automatic sizing trowel which can reduce ash supply personnel, increase plastering efficiency, reduce labor intensity and improve working conditions. It includes a handle with a built-in slurry conveying channel, a wiper plate for scraping the slurry onto the wall, and an electric switch on the handle. There is also a trowel box for storing slurry between the wiper plate and the handle. The trowel box assembly includes a box body and a slurry storage area placed in the box body. The invention can automatically sizing and store an appropriate amount of slurry in the slurry storage area of ​​the trowel box assembly in advance. Squeezed by the wiper plate, it will be sent to the slurry outlet through the slurry outlet hole and the slurry passage hole, and then flow out from the slurry outlet to be wiped on the wall, so that the mason can easily put the slurry with one hand. Putting it on the wall can greatly improve their work efficiency and reduce the labor intensity of masons.

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...

AI Technical Summary

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.
