An experimental setup was developed and manufactured to study a conveyor with a blade working body, which will improve the functional and operational characteristics of conveyors. When conducting a multifactorial experiment to determine the damage to grain material by the blade working body of the conveyor, the variable factors were: the diameter of the casing D, the conveyor loading coefficient ψ, and the rotation frequency of the blade working body n. Based on the results of experimental studies, corresponding regression equations and response surfaces were constructed to establish the influence of controlled factors on the damage to grain materials.

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.
