ABSTRACT:
A bin for storing and handling bulk material includes a fill opening through which material is introduced into the bin for storage and a discharge opening in a bottom portion of the bin through which material stored in the bin is discharged. The bin includes a primary bin support frame, and has at least one dump assembly with a bin floor panel that is hinged adjacent the discharge opening of the bin. The bin floor panel is pivotable from a generally horizontal position to an angled position for dumping bulk material into the discharge opening. The dump assembly includes a rigid secondary frame connected to the bin floor panel and pivotable with the bin floor panel. The bin further includes a flexible bin wall portion connected to the primary and secondary frames and the bin floor panel to form an enclosure for storage of bulk materials. The flexible bin wall portion is supported in an erect position by the primary and secondary frames for storage and discharge of bulk materials. The bin includes an inflatable bag underlying the bin floor panel for inclining the floor panel toward the discharge opening and thereby directing bulk material stored in the bin through the discharge opening.
