FUNCTIONAL-LINK STRUCTURAL MODEL OF THE WORKING PROCESS OF ROOT HARVESTING MACHINES

Abstract

The efficiency of root harvesting machines is regulated by the quality indicators of their work in accordance with
agrotechnical requirements, which primarily include indicators of loss, damage and contamination of dug up root crops with
components of soil and plant impurities. The aim of the work is to reduce the amount of free soil and plant impurities in the
collected heap by developing and analyzing theoretical prerequisites for the receipt and movement of the dug up heap by the
working bodies of root harvesting machines. Based on the theoretical analysis of the developed functional-link structural model
of the root harvesting machine operation process, which is built on the block-modular principle and using Laplace transforms,
mathematical models were obtained that describe the processes of intensification of the separation of structural components of
impurities from root crops, recorded in parametric and operator form. The developed dependencies that characterize the
impurity separation coefficient of each structural link allow optimization of the parameters of the working bodies of each
individual module of the root harvesting machine.
