Development of technology of mixture application on vertical surface

The object of research is the development of applying a consistency to a vertical surface using an automated device. One of the most problematic places is the poor quality of work at height and the danger associated with the life of workers. Currently, there is only a manual and semi-mechanized method of applying the mixture to a vertical surface. When applying plaster to a vertical surface inside a building, some countries use a plastering robot. In this case, the work is done with high quality and is serviced by two workers. Therefore, when studying this issue, the authors decided to develop a device with which it is possible to perform work on applying to a vertical surface from the outside of the building with high quality.
In the course of the study, technological maps were used, on the basis of which estimates were developed, which showed that the introduction of new technologies makes it possible to obtain up to 20 % cost savings on works, equipment and mechanisms. An economic effect was obtained from the developed technology. This is due to the fact that the proposed technology makes it possible to reduce the cost of work using the developed equipment, since the equipment serves 3 workers, namely 1 operator and 2 workers servicing this equipment. The proposed equipment has a number of features that make it possible to additionally mix the mixture at the outlet, edit the supply of the mixture, apply the required thickness evenly, in particular, control the quality of work. This makes it possible to choose the inclination angle, the thickness of the mixture and obtain indicators of the strength of the mixture and the number of losses. Compared to similar known methods, the mixture is fed automatically, which provides advantages such as quality control, safety precautions and reduces the risk of loss of life.
