Planetary mechanisms are used to create the working movement of operating bodies of metallurgical and mining machines. Rolling working bodies, for the drive of which the planetary mechanisms are used are increasingly used in the designs of harvesters. The processes taking place in the differential threshing devices of harvesters are poorly studied due to the lack of information about the properties of the material in the case of rapidly changing stresses in them. The present work is a result of the analysis of theoretical and experimental researches in threshing. We described the technological scheme of the shock–vibration threshing device and the principle of its operation. There were studied the possible options of the placement of rollers and a concave. The relationship between the angular velocities of a roll, rollers and a concave was found out. The installation of three–sided rollers on the threshing device according to the scheme proposed by us makes it possible to shake the whole threshed rice mass from 75 to 110 times per second.
