Study of the threshing process in an axial flow device

Abstract

The threshing apparatus is the most important element of a harvester, taking into consideration that both the threshing process, performance and the separation one depends on it. In the present case the experiments have been made on an axial flow thresher with tangential feed. Starting from the experimental date previously determined, after their processing, there were obtained the probability distribution Ss(x) and the density function Sd(x) of the seeds separated during the threshing and separating processes by using various types of mathematical proceedings. The final aim is to minimize the losses from the threshing apparatus, achieving as good as possible seed separation, namely a percentage over 99%.
