1. A collapsible storage system for flowable material, for use with an auxiliary system which is identical in configuration to the storage system, the storage system comprising:
a base frame;
an upper frame supported above the base frame such that the upper frame is movable relative to the base frame between a collapsed position and a working position in which the upper frame is spaced upwardly in relation to the collapsed position;
at least one storage silo comprising:
a discharge mechanism supported on the base frame comprising a rigid wall extending downwardly from an upper perimeter edge to a bottom end locating at least one discharge opening therein; and
a tubular wall assembly extending from a bottom end connected to the upper perimeter edge of the discharge mechanism to a top end connected to the upper frame so as to be extendable in overall height relative to the base frame with the upper frame between said collapsed position and said working position, in which a hollow interior of said tubular wall assembly is in open communication with the discharge mechanism to define the storage silo in the working position thereof;
wherein said at least one storage silo comprises a plurality of storage silos supported on the base frame in a longitudinal row;
wherein the storage system further comprises an unloading conveyor assembly extending along the base frame in a longitudinal direction of the longitudinal row in communication with each of the storage silos; and
wherein the unloading conveyor assembly protrudes longitudinally outward from at least one end of the base frame such that the unloading conveyor assembly is arranged for discharging onto the unloading conveyor assembly of the auxiliary system when the storage system and the auxiliary system are positioned longitudinally end to end with one another.
