Abstract
Abstract Apparatus for use in conjunction with large storage and settling containers containing stored material. The apparatus aids in removing said material from the container with a remotely controlled operation. The apparatus includes a housing supporting a receiver trough opening to receive material from an opening of the container. An auger conveyor is supported within the trough for removing material from the trough. A sliding bulkhead is supported by the housing for opening and closing access between the trough and container. A bulkhead retrieval mechanism controls the bulkhead. The auger moves the material from the receiving trough to a receiving drum located near a discharge valve opening to the trough. The trough and auger include individual sections which may be assembled and disassembled for purposes of maintenance and repair without removal of the housing and the material from the container.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
164 words
A conveyor assembly for removal of stored material from storage containers, the assembly comprising in combination: a support channel member received by an opening to a container from which stored material is to be removed, the support channel member forming a longitudinal channel; trough receiving means disposed within said longitudinal channel member for receiving material conducted through said opening, said trough means being supported by said channel member, said trough means being slidable within said support channel member and being adapted to be separated from said support channel member; an auger supported within said trough receiving means for removing from said trough means material received thereby; discharge means extending to said trough means and spaced from said opening for discharging material advanced by said auger; and retractable bulkhead means intermediate said trough receiving means and said opening for controlling access between said opening and said trough receiving means, said bulkhead means being supported by said support channel member independent from said trough receiving means.
Claim 2
Dependent Claim
164 words
A conveyor assembly for removal of stored material from storage containers, the assembly comprising in combination: a support channel member received by an opening to a container from which stored material is to be removed, the support channel member forming a longitudinal channel; trough receiving means disposed within said longitudinal channel member for receiving material conducted through said opening, said trough means being supported by said channel member, said trough means being slidable within said support channel member and being adapted to be separated from said support channel member; an auger supported within said trough receiving means for removing from said trough means material received thereby; discharge means extending to said trough means and spaced from said opening for discharging material advanced by said auger; and retractable bulkhead means intermediate said trough receiving means and said opening for controlling access between said opening and said trough receiving means, said bulkhead means being supported by said support channel member independent from said trough receiving means.
Claim 3
Dependent Claim
34 words
