STUDIES REGARDING THE INFLUENCE OF THE SIEVE OSCILLATORY PLAN-PARALLEL MOTION ON THE SEEDS SEPARATION IN CLEANING SYSTEMS FROM THE CEREAL COMBINE

摘要

The character of variation curve profile of the angular speed of sieve in oscillatory plane-parallel motion, in dependence from lengths values and positions of the sieve driving gearing elements, affect separation process, in sense to betterment or deterioration of this. This paper presents the variation curves profile of the angular speed of sieve in oscillatory plane-parallel motion from five types of driving gearing-bracket suspension and are analyzed differences among character of variation curves profile and presumptive influence of sieves separation process. Testing has been made by a laboratory research stand to analyze influence of this parameter in separation curves profile acquired experimental. Measurement data presented in this paper have a major relevance from designers and users of harvesting combines.
