Method of step-by-step development of a mathematical model of the process of separating impurities from root crops

Abstract

Harvesting root crops, such as large sugar and fodder beetroots, and long-term chicory roots is a technologically complex and ambiguous technological process. It consists of different structural successive technological operations of pruning, digging roots, cleaning the dug heap from impurities, loading clean roots into the hopper or in vehicles moving near the root harvester. The aim of the study is to increase the efficiency of the process of harvesting roots by analyzing existing approaches to mathematical simulation of the technological process of separating impurities from roots. The developed mathematical model allows describing at the highest-level more precisely the process of gradual separation of variously structured components of impurities from root crops by each cleaning working body, which are constituent units of technical systems of root-harvesting machines. The proposed mathematical model can be used to optimize the parameters of the working bodies and other processes, in particular for the separation of the harvested grain heap, preparatory processes of seed, and so on.
