ABSTRACT:
A collapsible hopper is used with a conveyor, for example a grain auger. The hopper is fastened onto the bottom end of the auger to surround the inlet. It has a flaccid side wall that is normally supported in a raised condition by a top, rigid hoop connected to the hopper base by a pair of springs. The springs allow the hoop to be deflected downwardly when engaged by another object, for example a truck box when it is dumping into the hopper. An over-center linkage allows the springs to be released so that the flaccid hopper wall can collapse, allowing insertion of the hopper in this collapsed state into a position where there is insufficient clearance to insert the fully-raised hopper.
