MULTIDRIVE BELT-ROPE CONVEYOR Russian patent published in 2012 - IPC B65G15/08 B65G17/02 B65G23/08 B65G23/10 

FIELD: transport.

SUBSTANCE: conveyor comprises frame (1), continuously looped on driving (4) and tensioning (5) drums belt contour (6, 7). Inside the belt contour, looped on driving pulley integrated with driving drum and on located at conveyor tail part fixed end unit (8) pulling contour (9) of two ropes (10, 11), resting on horizontally oriented flanged rollers (12, 13) on load-carrying branch of belt is located. Boards of belt on its load-carrying branch rest on tilted rollers (14, 15), and on nonoperational branch - on rollers (16). Rollers for supporting belt and rope are located with mutual displacement along conveyor length. Along conveyor length, between upper and lower branches of ropes, intermediate flanged driving pulleys (19, 20) connected with driving units (17) and mounted on one shaft (18) are located with possibility to be rounded by ropes of upper (21) and lower (22) branches of pulling contour at angles of 360 degrees. Points of driving contour upper branch ropes run-on over intermediate driving pulleys are located from the side of tensioning drum, and points of driving contour lower branch ropes run-on over driving pulleys are located from the side of driving drum with head driving pulley. Located at conveyor tail part the end unit in the form of double pulley for rope pulling contour is equipped with screw tensioning device with possibility of its displacement relative to conveyor frame.

EFFECT: increased conveyor length, simplification of conveyor's structure.
