Analysis of the threshing process in the interriffle space of the threshing device

Abstract

By implementing a factor experiment in the laboratory the regularity of the change in the degree of threshing of ears in the space between the riffles of the flail’s threshing drum was stated. A mathematical model of the threshing process in the space between the riffles is given. The obtained results broaden the understanding of the nature of threshing by grinding in the threshing space of a combine harvester. The tests used unmilled ears of Donskaya ostistaya wheat, freed from grains by 70-80%. It is determined that the complete threshing is carried out for one impact of the flail and with minimal compression of the plant mass. Conclusions are made about the results obtained.
