ABSTRACT:
A device for raking flowable material from a storage facility, with a plurality of storage units such as bunkers, silos, stockpiles, has a bunker table positioned at the bottom of the storage units and a rake tunnel positioned above the bunker table. A raking carriage is positioned in the rake tunnel above the bunker table so as to be moveable in a longitudinal direction of the rake tunnel along the bunker table. A drive unit, including a gear box and a drive shaft, is connected to the raking carriage. A raking wheel is rotatably connected perpendicular to a rotational plane of the raking wheel with the drive shaft to the raking carriage. The bunker table has a longitudinal slot. The raking wheel rakes with two opposite sides the flowable material on the bunker table through the slot of the bunker table onto a continuous conveyor system located under the bunker table. The raking wheel is displaceable with a shaft relative to the raking carriage and the slot of the bunker table has widened circular cutouts for allowing displacement of the raking wheel from a first position above the bunker table to a second position below the bunker table.
