RESEARCH OF THE WORKING PROCESS OF THE CLEANING SYSTEM OF MACHINES FOR HARVESTING ROOT CROPS

Abstract

Conducted the theoretical and experimental studies of the combined cleaning system functioning process by analyzing the motion of fodder beet through the working surfaces of feeding conveyor and auger installed above it. We have got analytical and empirical process model of fodder beet oblique sub-hiton the augerturn that characterize the dependence of the total rate of sub-hit coefficient of technological interaction of roots and depth of root damage on the main parameters of combined cleaning system. We found out the rational limits of basic structural and kinematic parameters of combined cleaning system by providedminimum offodder beet damage. Particular importance for improving the design and technological level and individual working bodies of the combined cleaning system should be given to issues of general engineering problems of machine design: improvement of working bodies and other structural elements of the combined cleaning system based on a deeper analysis of physical and mechanical properties of roots. Characteristics of fodder beets, as an element of the system "machine-working body-root crop", must be considered as a set of different mechanical qualities and parameters that are decisive in the total mechanical action on the object, their allowable level and range of structural and kinematic parameters of workers bodies. When optimizing the parameters of transport and technological systems of the root of the harvesting machine, which have working bodies of screw mechanisms, at the stage of their design it is advisable to first build a mathematical model of the technological process of root cleaning system parameters.
