A METHODOLOGICAL APPROACH TO THE STUDY OF EFFICIENCY OF TECHNOLOGICAL PROCESSES OF GRINDING AND SCATTER STRAW COMBINE HARVESTER
The article discusses a methodological approach to the study of the effectiveness of technological subprocesses of combine harvester, in particular grinding and dispersion of the plant part of the crop during harvesting. The research is based on the accepted provisions of the General logical method and methodology of system analysis. In the course of achieving this goal, it was revealed that the technological process of the combine harvester could be considered as a set of individual subprocesses, which are characterized by structure formation. This means that there are main and secondary sub-processes in the technological process of the combine, for which there is an influence and a partial mutual inclusion. This allowed us to consider the shredder-spreader straw combine harvester as a transforming technical system consisting of a set of different technical subsystems, which is reflected in the structural schemes presented in the article. Thus the input and output indicators characterizing performance of technological subprocesses of the shredder-spreader of straw of the combine are opened. As a result of the analysis of the output indicators of the technological subprocesses of the shredder-spreader combine, the qualitative and quantitative indicators of the technological subprocesses of the shredder-spreader are revealed. The material under consideration in the article further allows us to formulate a structural and computational model of subprocesses of the grain harvester shredder-spreader, which reflects the interaction of individual elements in the system "object of influence - environment - technical subsystem».
