Device for continuous discharging bulk material from ships

摘要

The unloader consists of a gantry with boom and bucket chain conveyor. The front deflection pulley (5) of the conveyor (4) is fastened vertically freely pivoted to a bearing (8) on the conveyor, via a front link arm (7). The rear deflection pulley (6) is similarly fastened via a rear link arm (9) to another bearing (10). A coupling element (11) between the pulleys transfers the movement of the front pulley to the rear one, so that both execute the same vertical movement. The rear link arm engages on a stop (14) on the conveyor frame, and supports itself on the frame via a spring (15).
