SCREW CONVEYOR FOR TRANSPORTATION OF LOOSE LOADS Russian patent published in 2004 - IPC

FIELD: mechanical engineering; transportation of loads curvilinear path. SUBSTANCE: proposed screw conveyor contains drive auger shaft with screw blade mounted in cylindrical trough. Guide of cylindrical trough is made curvilinear, and drive auger shaft is made in form of flexible shaft formed by double-lay rope, and screw blade is made in form of flat strand rigidly connected by one of its semiround parts to two adjacent outer round strands of double-lay rope. Larger axis of flat strand is located in diametric plane of double-lay rope. EFFECT: increased efficiency of transportation of loose loads over curvilinear path. 3 dwg
