Scraping device for rough wall surface

Abstract

The invention discloses a scraping device for a rough wall surface. The scraping device comprises a vibration absorption seat, wherein a shell body is arranged at the outer side of the vibration absorption seat; a bottom plate is arranged below the vibration absorption seat; a rubber cushion is arranged between the bottom plate and the vibration absorption seat; a motor is arranged at one side ofthe upper end of the vibration absorption seat; a cam is fixedly connected with an output shaft of the motor; one end of the cam is rotatably connected with a first connecting rod; a second connectingrod is rotatably connected with one end, far away from the cam, of the first connecting rod; a rod groove sleeves the outer side of the second connecting rod; the lower end of the rod groove is fixedly connected with the vibration absorption seat; one end, far away from the first connecting rod, of the second connecting rod is rotatably connected with a clamping device; the upper end of the shellbody is fixedly connected with a connecting block; the connecting block is rotatably connected with a clamping device through a third connecting rod; a scraping rod is fixedly connected with the inner part of the clamping device. The scraping device for a rough wall surface provided by the invention has the advantages that the structure is novel, the running is stable, the problems of large manual operation intensity and low efficiency is solved.

Description

Technical field [0001] The invention relates to the technical field of architectural decoration, in particular to a leveling device for rough wall surfaces. Background technique [0002] In the construction of each building, the wall surface is covered with mortar, such as cement mortar or lime mortar, and smoothed to make the wall beautiful and easy to use. At present, the mortar covering and scraping of the wall is averagely operated manually, that is, after the mortar is applied to the wall with a plaster knife and a wooden board, a square wooden pole or aluminum alloy square pipe is used to smooth the wall. The work efficiency is very low and the quality is very low. It is difficult to guarantee the flatness, compactness and smoothness, especially in the leaking place after screed, it is difficult to ensure the consistency with the surrounding mortar surface after the grout. In the construction and decoration industry, the leveling of indoor and outdoor walls is an important...

AI Technical Summary

Problems solved by technology

The current wall surface treatment is mainly completed by manual use of scrapers, which is labor-intensive and extremely low in efficiency. The level of flatness mainly depends on the experience of the workers. In the case of multiple people working together, it is difficult to ensure the flatness of the wall after construction.
