INCLINED BELT CONVEYOR Russian patent published in 2009 - IPC B65G15/16 

FIELD: mechanics.

SUBSTANCE: inclined belt conveyor consists of the main and additional belt. Lower flight (9) of the additional belt has longitudinal near-zero tension. Movement of upper flight of the additional belt along the supporting devices is provided at non-negative resistance of its movement. Drive drum of the additional belt is located in the conveyor lower part immediately after loading device (11) in the direction of movement of load-carrying flight of the main belt, under it there located on parallel axis (16) and kinematically connected thereto is cylindrical roller (17) installed with the possibility of being held down to the flight of the additional belt, which runs off the drum, and fixed in this position. Kinematic connection is made in the form of drum shells fixed on side edges and roller of rings that are frictionally interrelated to each other. Mechanism of holding the roller down to the drum is made in the form of two screw pairs (20) installed with the possibility of shifting housings of bearings (23) of roller relative to a fixed vertical post whereon there fixed are bearings of drive drum of the additional belt. Hold-down devices are made in the form of loops (25) made from round-link chains and suspended to frame (24). Distance between suspension points of each loop to the frame is more than width of the additional belt.

EFFECT: simplifying the conveyor design, improving life time of the main and additional belts, reducing consumption of energy required for transportation, and improving conveyor operating reliability.
