Creation and assessment of breeding material of Lucerne with the heightened level of azotfixation

Abstract

The purpose. Heightening efficiency and quality of production process of separation of potato heap by improvement of construction of spiral separator of vibration type and theoretical justification of its rational parameters under condition of exclusion of damage of tubers of potato.Methods. Theoretical studies of the improved separator of potato heap were carried out with the use of basic provisions of higher mathematics, theoretical mechanics, and also creation of programs for PC and construction of graphical dependences and their analysis. Results. Equivalent scheme is created of interaction of tuber of potato with the surface of cantilever spiral springs on the basis of which motion characteristics of flight of a tuber before its impact with elastic surface of the mobile transporter. Conclusions. New mathematical model of flight of a tuber of potato from the surface of spiral separator and its impact with deflecting transporter is built. On the basis of the gained analytical dependences it is possible to study theoretically kinematic parameters of spiral separator of potato harvester with improved construction at its interaction with a tuber under condition of its non-damaging.
