BELT BUCKET ELEVATOR Russian patent published in 2004 - IPC

FIELD: mechanical engineering; conveyor transport; elevators. SUBSTANCE: in proposed belt bucket elevator containing endless flexible belt with fitted-on buckets closed on drive and tensions drums and forming load-carrying and return runs with guides for runs, and device for catching torn off belt. U-shaped levers are installed for turning and tilting downwards on side walls on housing on axle-shafts locating along elevator axis in its upper part to enclose each run of belt with buckets. Round-link chains are hinge-connected to ends of U-shaped lever, and twin horizontally orientated rods are provided whose free are arranged in sleeves for displacement and provision of interaction of rod ends. Chains are installed with possibility of free sagging. Straight levers spring-loaded relative to housing are installed for turning at side of load-carrying run of belt housing by means of axle-shafts. Roller is installed in middle part of levers for rotation and engagement with load-carrying run from opposite to buckets. Ends of straight levers are provided with forks to enclosed pins on sleeve and travel relative to pins. Belt guides are arranged at level of chain lower edges. Round-link chains can be made double-row on each u-shaped lever. Sag of chain can be taken greater than height of bucket for one row and pitch of buckets on belt for other row. EFFECT: improved efficiency in operation, simplified design of running part, reduced labor input at replacement and repair of buckets and restoration of torn-off belt. 3 cl, 5 dwg
