<p>To unload bulk material (1) particularly from a vessel (2), an endless conveyor belt (10) is used which is provided with U-bent drivers (12) and side corrugated edges (11). The endless conveyor belt does not merely get the bulk material (1) out of the vessel (2) but also takes said bulk material automatically. The conveyor belt (10) is suspended in a headframe (3) to an upper drive drum (20), both compartments (10' and 10'') being directed downwardly, and is free to circulate under the headframe (3) as a loop (21) simply formed under the action of the weight of the conveyor belt, without using any additional tensioning device. The headframe (3) is lowered into the bulk material (1) until the loop (21) is shortened in the vertical direction and the conveyor belt (10) is immersed into the bulk material (1) which is collected by its drivers (12). A vertically displaceable limiting drum (27) in the loop (21) prevents an excessive lateral displacement of the loop (21) as a reaction to the taking process.</p> |
