Abstract

The work considers the solution to the urgent problem of reloading grain into vehicles and reducing its damage. The possibility of throwing grain at a given range by creating an appropriate ballistic flight path by adjusting the speed of the electric drive of the belt when it is powered by a frequency converter is substantiated. The problem of reducing the focus of grain scattering by forming the flow of grain and controlling its movement not only when moving on the belt, but also after the separation of the flow and its movement in the air. Focusing of the lower layer is achieved by giving it an additional initial speed, which is provided by the air flow from the fan installed under the belt. For the frequency converter of the electric drive of the fan, in the form of a regression model, the control law which considers parameters of grain and necessary range of transportation is synthesized. Experiment planning theory was used to synthesize the control law.
