Abstract:Aiming at the present situation of interior wall plastering inconstruction industry most of using artificial painting way which lead to low efficiency,so far,combining the existing semiautomatic plastering machine can be automatic, but the mortar is easy to fall off, the wall is difficult to align, and the shotcreate machine have high efficiency with characteristics of a large amount of workload, by integrated advantages of both sets of mechanical and electrical integration, a new interior wall smart plastering machine was put forward which fully based on a pneumatic control system.Among which the executive components of the device of the system were select or valve pneumatic motor and cylinder.Through setting the electromagnetic valve connected with plastering mechanism and spraying mechanism travel switch in the pneumatic system circuit,and to realize the intelligent device to cooperate with the lifting, spraying, walking and other movement, the automatic plastering work was finished.Working safety and reliability, high efficiency, low noise, fast response of the Intelligent Plastering Machine, has high popularization and application value in the construction industry.
