Continuous bulk material conveyer

In a movable continuous conveyer for removing bulk material, especially for unloading ships, including a boom that has a conveyer belt, is pivotably connected to a movable support structure, and is adjustable in height via a luffing mechanism in the form of a first linear drive, also including a steep-rise conveyer system with a conveyer belt for unloading bulk material that is suspended on the free end of said boom, is pivotable in a vertical plane via a second linear drive about a horizontal axis, and has a cover belt conveyer, the end regions of the belts of the steep-rise conveyer system are guided about guide means, further including a material-receiving part for a receiving region of said steep-rise conveyer system, with said material-receiving part including two casting reels that can be driven in opposite directions and are mounted in a support structure, the improvement wherein:

• said support structure for said casting reels includes three control linkage groupings, a first one of which serves for an articulated interconnection of said casting reels, and the other two of which serve for an articulated connection of said casting reels with shafts of adjacent lower ones of said guide means for said belts of said steep-rise conveyer system;
• one of said shafts of said lower guide means is adapted to be shiftable in height in further guide means via a third linear drive;
• a fourth linear drive is provided for adjustment of the quadrilateral articulation defined by said three control linkage groupings and said shafts of said lower guide means for said belts of said steep-rise conveyer system;
• during a pendulum movement of said steep-rise conveyer system transversely through, for example, the hold of a ship, a respectively leading one of said casting reels is disposed higher than the other casting reel such that both casting reels pick up at least nearly the same amount of material;
• a first control mechanism is provided for adjusting said second linear drive of said luffing mechanism, as a function of deflection of said steep-rise conveyer system out of a vertical position, in such a way that the course of movement of said casting reels across said bulk material is horizontal;
• and
• a second control mechanism is provided for adjusting said third and fourth linear drives for adjusting said quadrilateral articulation and for shifting the height of the leading casting reel, as a function of deflection of said steep-rise conveyer system out of a vertical position, in such a way that during said pendulum movement of said steep-rise conveyer system, said casting reels always assume the same position relative, for example, to said ship, and a stream of bulk material picked up by said casting reels is always directed at least nearly perpendicular to said first one of said three control linkage groupings that interconnects said casting reels and is directed into said receiving region of said steep-rise conveyer system.
