DRAG PLATE CONVEYOR Russian patent published in 2009 - IPC E21F13/08 B65G19/26 

FIELD: mining.

SUBSTANCE: invention refers to mineral resource industry and can be used for transporting loose masses in wells, coal strip mines and storage areas. On the ends of the conveyer line up to 2 km long there located are power-drive stations which include extension drive shaft installed in the supporting rolling assemblies. At that, on the shaft ends there rigidly fixed are drive sprockets for transmitting rotation to the shaft through flexible chain connections from even number of electric drives, and in the middle of the shaft there rigidly fixed are drive sprockets for the conveyor pull chain drive. At that, on horizontal links of the pull chains there rigidly fixed are drag bars at a distance of 200-300 mm from each other. Metal plates are hinged to the drag bars from above and form a flexible hinged metal transportation belt with friction factor of 0.15.

EFFECT: developing reliable design of drag conveyor, which allows transportation of loose and plate materials for up to 2 km and more with the angle of slope of loose material transportation plane up to 40°, and increasing capacity up to 1500 t/h.
