Apparatus for emptying bulk material from a storage chamber comprising a first rake in the storage chamber for transporting material in the longitudinal direction, the first rake being movable vertically and transversely. A vertical transport device is mounted in the storage chamber for transporting material from the storage chamber vertically upwards for removal from the storage chamber. A second rake is mounted in the storage chamber transversely and the second rake is positioned adjacent one end of the first rake at a level therebelow for receiving material longitudinally transported by the first rake to in turn transport the material transversely to the vertical transport device. The vertical transport device comprises a plurality of vertically displaceable buckets with a cover plate arrangement positioned in front of the buckets at a level below the second rake and associated with a mechanism for adjusting the cover plates for downward movement as the storage chamber is emptied of material.
Apparatus for emptying bulk material from a storage chamber, said apparatus comprising first rake means in said storage chamber for transporting material in the storage chamber in a first direction therein, means for moving said first rake means vertically, means for moving said first rake means transversely of said first direction, vertical transport means for transporting material from the storage chamber upwardly for removal from said storage chamber, second rake means in said storage chamber extending at an angle with respect to said first rake means for transporting material in the storage chamber in a second direction therein to said vertical transport means, and means for moving said second rake means vertically, said second rake means being positioned adjacent one end of said first rake means for receiving material transported by said first rake means in said first direction and for transporting the material in said second direction to said vertical transport means.
