Abstract

Screw conveyors are widely used in the agricultural sphere of production for moving, mixing, dosing products and the like. The improvement of existing designs of screw conveyors and the substantiation of their rational parameters and modes of operation allows us to expand the functionality of technological operations and increase the productivity of mechanisms in general.

Based on the analysis of existing screw mechanisms, a screw conveyor-chopper of root crops with a combined working body was proposed. It is made in the form of a screw, which is installed in the casing. G-like knives-choppers are fixed on the spiral turns of the screw. According to the results of experimental studies, a regression equation was obtained, which describes the nature of changes in the productivity of the screw conveyor-shredder of root crops, depending on the frequency of rotation of the screw and the screw diameter. Based on the analysis of the constructed response surface and its two-dimensional cross-section, it was established that the main array of approximated values of the productivity of the screw conveyor-shredder of root crops is in the range from 0.8 to 2.3 kg / s. The research results are a further step in the development of methods for substantiating the parameters of screw mechanisms.
