Abstract
The production of rooted chicory crop is one of the traditional branches of the agro-industrial complex of Ukraine. Rooted chicory is used in the pharmaceutical, coffee, alcohol and confectionery industries. The main reason for the decline in chicory production is the imperfection of the technique for its harvesting and the non-compliance of the quality indices of its operation with agrotechnical requirements. Mechanized harvesting by outdated complexes of root cropping machines results in significant loss of chicory root crops, which can be 45...60% depending
on soil and climatic conditions of harvesting. An important factor for the effectiveness of the development of operating devices for the digging of chicory root crops is to take into account their agrobiological and physico-mechanical
properties. They sufficiently correct the mechanical and technological processes and phenomena that are characteristic of the operating processes of complex dynamic systems, "root crop-operating device-soil environment". Based on the conducted modelling of the technological process, analytical dependencies are developed to determine the power of chicory root crops digging by combined operating device. The developed models take into account the rheological properties of the soil and root-plant environment and the type of dynamic load of the operating device. The results of
the investigations are the next step in developing of methodology for substantiating the parameters of the digger operating bodies.
