Abstract
In order to configure a bell and hopper for shaft furnaces, in particular, blast furnaces, comprising a charging bin with a feed tube, a rotating chute carrier with rotary drive, a swiveling chute in the interior of the furnace with drive means arranged external to a housing, in a less failure-prone and a wear resistant way, the drive means for the swivel movement of the chute are to comprise: at least one motor ( ) which drives by a respective pinion ( ) a crown gear ( ), wherein the crown gear ( ) engages the spindle gear wheels ( ) of at least two spindles ( ) distributed about the periphery of the bell and hopper external to the rotating chute carrier ( ) for generating a lifting and lowering movement of the spindles, as well as means ( ) for transmitting this vertical movement of the spindles onto the tilting shafts ( ), which penetrate the inner wall ( ) of the chute carrier ( ) and from which the chute can be suspended, for generating a swivel and tilting movement of the chute.
