Description

Wall planing machine

Technical Field

The invention relates to a small-sized electric tool for mechanical and electrical products, in particular to a wall planer which can remove old white, paint and paint coatings on wall surfaces and finish and polish the surfaces of buildings and cement products.

Background

At present, various electric tools exist in the market, and only no high-efficiency electric tool capable of cleaning old white, paint and paint coatings on wall surfaces, and finishing and polishing surfaces of buildings and cement products is available. Because no proper and efficient tool is available, the cleaning can be carried out by only using a little by little manual work, and the defects of low efficiency, poor effect, high labor intensity, labor hour expense, construction difficulty increase, cost investment increase and the like exist.

Disclosure of Invention

In order to solve the problem that no ideal tool is available in the field and overcome the existing problems, the invention provides the wall planer of the small-sized electric tool for the electromechanical products, which not only can quickly, efficiently, thoroughly and cleanly remove old white, paint and paint coatings on the wall surface, but also can be used for finishing and polishing the surfaces of buildings and cement products to ensure that the products are more perfect.

The technical scheme adopted by the invention for solving the technical problems is as follows: a miniature motor is used as a power mechanism and is provided with a shell, a group of worm gears or other gear sets are mechanically installed in the shell to be used as a power transmission mechanism, a group of working part assemblies consisting of an inner roller, an outer tile block and working teeth are respectively installed on worm gear spline shafts with the same length at two sides outside the shell, and a bracket capable of adjusting the working depth of the working teeth is arranged on the shell; the micro motor, the power transmission mechanism and the working component assembly form the high-efficiency wall planer. The electric tool with the same function can also be formed by taking an angle grinder, an electric hand drill and an impact drill as power mechanisms and arranging a working assembly part with a corresponding shape structure on the power mechanisms.

The invention has the beneficial effects that: the wall planing machine can rapidly, efficiently, thoroughly and cleanly clear old white, coating and paint coating on the wall surface, can also be used for finishing and polishing the surfaces of buildings and cement products, effectively improves the product quality, has high working efficiency, good effect, saves working hours, ensures the quality, lightens the labor intensity, improves the working environment, reduces the manufacturing cost, reduces the pollution, ensures the health of workers, and is safe, reliable and clean
