The purpose is improving the efficiency of the technological process of threshing and separating the grain pile in a multidrum threshing-separating device due to the substantiation of the technological modes of the work of threshing drums. The influence of technological parameters of the three-drum threshing-separating device of a grain-harvesting combine on the process of grain separation has been studied experimentally. Models of the grain separation process are obtained depending on the speed of rotation of the drums and the supply of technological material for threshing, based on the results of the experimental research. modeling the process of grain separation depending on the speed of rotation of the drums and the supply of technological material for threshing allows to determine the quantity and quality of the mass that each of the three drums separately threshed.
