Automatic mortar spraying and roll levelling machine for wall face construction of building

Abstract

The invention relates to the field of building construction, in particular to an automatic mortar spraying and roll leveling machine for wall face construction of a building. The automatic mortar spraying and roll leveling machine comprises a trolley, a mechanical arm, a mechanical arm driving mechanism, a hydraulic power unit, a spraying mechanism and a roll leveling mechanism. Compared with theprior art, the automatic mortar spraying and roll leveling machine is more stable and does not fall down; roll leveling is conducted on mortar sprayed on the wall face by a roller, the roller is driven by the mechanical arm to achieve going-up and going-down, so that repeated roll leveling is conducted on the spraying face in the vertical direction; and the automatic mortar spraying and roll leveling machine abuts against the wall face all the time through double control of driving devices of the trolley and the roller, the roller is excessively pushed and abuts against the wall face, and theroller can be kept in abutting-against connection with the wall face through springs; and automatic mortar spraying roll leveling operation of the wall face can be achieved by the automatic mortar spraying and roll leveling machine after the functions of the spraying mechanism is synthesized, manual labor intensity is greatly relieved, operation efficiency is improved, and potential safety hazardsof high attitude operation of workers are avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an automatic spraying and rolling machine for wall surface construction of buildings. Background technique [0002] In building construction, in order to level the wall, protect the wall or modify it, a layer of lime mortar is usually applied to the outer surface of the wall made of red brick or concrete. At present, the lime slurry is first applied to the wall by manual means, and then the wall is smoothed by a scraper or a roller. This manual plastering method is not only labor-intensive, but also suitable for plastering at high places on the wall. It is also necessary to set up a high platform in addition, so not only the construction period is lengthened, but also the personal safety hazards of working at heights are relatively large. [0003] After searching, it is found that the invention with the patent number CN200520073490.4 discloses a wall spraying machine and ope...

Problems solved by technology

[0006] However, this invention also has the following disadvantages: (1) the boom is used to drive the movement of the spray head, which is not stable enough when it is raised, and it is easy to cause the equipment to fall; (2) it mainly solves the problem of mortar spraying, and the problem of leveling is only It is roughly mentioned that a scraper is installed on the second boom section close to the nozzle, and the scraper moves synchronously with the nozzle to smooth the mortar, but the specific position and working principle of the scraper are not explained.
