Theoretical studies of the technological process of harvesting chicory root crops

Abstract

The decrease in the production of chicory root crops, which are valuable raw materials for the production of various products, is restrained by the low level of mechanization of their harvesting processes and unsatisfactory indicators of losses and contamination by impurity components. The purpose of the work: reduction of the second supply of impurities during the collection of chicory roots due to the development and analysis of analytical dependencies that functionally describe the process of collection of chicory roots by the working bodies of a combined single-disc digger. Based on the analysis of graphical dependencies, it was established that: the second supply of general impurities varies from 5 to 18 kg/s; second supply of loose soil – in the range from 4 to 15 kg/s; second supply of vegetable additives - from 0.06 to 0.1 kg/s. The obtained mathematical models are the initial dependencies for further substantiation of the parameters and modes of operation of the transport and cleaning working bodies of the root-harvesting machines.
