APPROACHES TO SUBSTANTIATING TECHNOLOGICAL SCHEMES OF SPRAYERS FOR PROTECTING GRAIN CROPS
Abstract
Results are given from studies on substantiating technological schemes of engineering tools with forced precipitation of sprayed drug on the underlying surface to protect grain crops from pests, diseases and weeds. Variants of technological schemes of engineering tools developed should be formed and evaluated based on combined function-and-structure approach using the methods of value analysis. This analysis includes determining a number of functions of the future product, building its functional model, searching and forming decision variants as to functions, building a structural model of the product, building its structure-and-function model, evaluating variants and choosing tools (technical solutions) and promising technological schemes. By the method of expert evaluations using comprehensive indicators and their numerical values of weighting factors, the promising technological scheme of the sprayer with forced precipitation of sprayed drug on the underlying surface has been substantiated. When carrying out protection activities, the hydraulic fluid can efficiently be precipitated by the inertial-gravitational method. The use of monodisperse spectrum of spraying with forced precipitation of droplets on the objects treated allows increasing the precipitation of these droplets up to 90 percent and more.
