Abstract
The article presents the design of the elastic brush screw working body of the screw conveyor, which makes it possible to reduce mechanical damage to grain, reduce dangerous loads caused by forced rolling when grain material is chocked during transportation. The relationship between the design parameters of elastic brush screw working bodies fibers and force loads on grains with elements of spherical surfaces and the conditions of their chocking during transportation is established. The calculation scheme for determining the parameters of grain transportation by an elastic brush screw working body is presented. The equation for determination of the allowable external load on the grain in the perpendicular direction to the flights of the elastic brush screw working body during transportation in the conveyor is derived. The condition of grain chocking between the fibers and the inner surface of the screw conveyor housing is determined.
