Pilot installation for applying protective coating on the surface of the agricultural equipment

Abstract

Abstract Agricultural machinery is operated in difficult conditions and severe environment. Due to contact with road surfaces, soil, plants, fuels and lubricants, as well as fertilizers and pesticides, when changing temperature conditions and under the influence of a number of other factors, surfaces of agricultural machinery become old and corroded, which reduces their performance and worsens some of its parameters. Most agricultural machines are operated from 10-15 to 55-60 days during the year, and for the remaining time, they are subject to high-quality storage. During long-term storage, the dimensions of parts change due to corrosion, as well as the quality of their material decreases due to structural transformations and residual deformations caused by the machine’s own weight. Efficiency and its service life can increase by 10-15% due to the application of a protective coating on the surface of agricultural machines, which reduces the influence of external factors on their safety. The use of a developed spray gun in the design of a hydraulic installation for applying a protective coating on the surface of agricultural machinery allows one to reduce unit costs by 13.8% and electricity costs by 12.3%. The economic effect of using a hydraulic coating system with the developed spray gun will amount to 75,539.3 rubles per year when processing 124.9 m2 of agricultural machinery surface.
