Abstract

The problem of reducing the grain materials damage whilst their transportation by screw conveyors hasn’t been solved completely despite a great number of research dealing with determination of the best parameters of screws. Agricultural materials damage during their transportation can be reduced considerably by using the elastic surfaces of screws whose parameters minimize the damage and power capacity of the technological process and simultaneously provide the necessary efficiency. The article has presented a new design of a screw conveyor with sectional elastic surface aimed at reducing the grain material damage degree whilst its transportation. Theoretical calculations of a grain-screw conveyor elastic section interaction have been made. The most efficient parameters of elastic sections interactions with the grain material of hemisphere-cone shape have been substantiated on the basis of obtained analytical dependencies. The impact of elastic screw design and kinematic parameters on the loose material flow behavior in the area between the adjacent sections which are overlapped has been determined.
