Abstract

This article presents a theoretical study of modeling the movement of a mixture in a dielectric sorting plant for alfalfa seeds. Theoretical studies were carried out using the general laws of mechanics and mathematical modeling of alfalfa seeds, taking into account their physical and mechanical properties. The results of a theoretical study on modeling the detachment conditions of alfalfa seed heap particles and particle dynamics along the casing and pitched boards of a dielectric sorting device are presented. The differential equation with the initial conditions was solved by numerical methods of "Runge-Kutta-Felberg" with automatic step selection. The components of a heap of alfalfa seeds, depending on weight and size, at each moment of time, have different trajectories, therefore, the dosed heap must be localized and guided using an additional device - a casing equipped with a ramp board. Theoretically substantiated parameters make it possible to determine the connection points of the ramp board with the casing of the metering drum of the dielectric sorting device.
