Search agricultural machinery design, including wide spread boom sprayers is impossible to implement qualitatively without carrying out experimental investigations. Therefore, this paper is focused on the important aspects of preparation method for experimental research. Particularly, the analytical model for determining the approximation curve nature and the method of the calibration factor setting are given. The results of processing the experimental research oscillograph with reception of graphical dependences of normal tension in intersection of the investigated element of the metal construction are given.
The efficiency of chemical working mixture application on the surface of agricultural plants by rod sprayers has been studied in the paper under consideration. The analysis of specific fractures of main crops sprayed areas with pesticides in agro-industrial production in 2018 was made. The method of the sprayer efficiency assessment was described and some graphical and analytical dependences for selected slit sprayers on the formation of the working mixture spray dispersion and the pressure choice in the pressure mains on the sprayer speed at specified spraying rate were built.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
