SPIRAL-SCREWING DEVICE FOR GRAINING OF GRAIN MATERIAL

The present article is devoted to the study of technological processes that occur when a grain embankment is torn by a device with a working member in the form of a spiral screw in the conditions of grain storage facilities, in particular, theoretical and practical research of processes in the device for stirring grain. The graphic relationship of the speed of movement of the technical means of stirring grain to the grain embankment and the ability of the technical means to pass through the amount of grain embankment at different rotational speeds of the spiral screw are compared with theoretical studies. As a result of the studies, rational values of the parameters of the grain torsion device were obtained, as well as regression equations allowing to determine the necessary rotation frequency of the spiral screw in order to provide the required device capacity at different spiral pitch. In this comparison of the results obtained experimentally and theoretically showed that the convergence of the results is 94%.
