Investigation of Bulk Material Transportation by Screw Conveyer with Hinge-Pan Operating Device

The article presents a new design of a hinged and sectional working body and substantiates its optimal parameters for ensuring the movement of loose materials along curvilinear routes. Analytical dependencies have been derived to determine the rational design and power parameters of the hinged-sectional working body, and the functional dependencies of the minimum permissible radius of curvature of the R C technological highway on the angular rotation of adjacent sections and their design parameters have been established. The axial speed and power of cargo transportation by the articulated-sectional working body of the screw conveyor along a curved route have been determined. Experimental studies have been conducted to determine the influence of the number of revolutions, the height of material lifting and the radius of curvature of the flexible helical sectional working body R C on the torque T , as well as the determination of the influence of the number of revolutions n , the filling factor of the main line ψ and the diameter of the main line D on the performance Q when transporting loose materials.
