Abstract: A bin unload conveyor for unloading grain through a raised floor of a bin. A removable cover is vertically supported by a plurality of removable ribs to cover the span of a removable midpan. The removable components allow for easy installation and removal to allow maintenance of the bin unload conveyor mounted under the raised floor. A central pit having a central pit cover also allows easy installation and maintenance access. A drive roller and sweep drive sprocket disposed in the central pit are accessible for maintenance upon removal of the central pit cover. A belt of the bin unload conveyor can be maintained in place without removal of the raised floor.

Abstract: An unloading conveyor system for unloading grain through the floor of a grain bin. A removeable cover is vertically supported by the plurality of ribs to cover the span of the midpan to allow maintenance. The midpan comprises a plurality of slots and ledges to receive and support the ribs to allow easy installation and maintenance. A central pit having an internal portion and an access support wall also provides easy installation and maintenance. The first bearing mount, second bearing mount, and roller are all accessible for service through the internal portion of the central pit.

Abstract: We disclose an apparatus for maintaining a flow of grain moving toward a rotating sweep conveyor. A rake extends longitudinally along the sweep. The rake is disposed along the leading sidewall of the sweep such that the rake is in the path of movement of the sweep as the sweep rotates within the bin. The rake has a plurality of projections that protrude from a shaft. A reciprocating drive assembly is connected to the driven roller and to the shaft. The reciprocating drive assembly causes the shaft to move forward and backward along the longitudinal axis of the sweep. The reciprocating shaft movement causes the projections to engage grain piles in the path of the sweep, causing the pile to collapse into a flowable particulate to be received by the sweep.

Abstract: A bin wall cleaner for a sweep conveyors and augers for removing residual grain located near the bin wall out of reach of the sweep conveyor and providing sweep coverage for non-uniform bin walls. The bin wall cleaner has a grain engagement member that extends outwardly from the distal end of the sweep. A biasing member maintains the grain engagement member extended toward the bin wall. A wall engagement member is attached to the grain engagement member to ensure the bin wall cleaner tracks with the bin wall. The grain engagement member extends by pivoting or telescoping at least one blade.

Abstract: We disclose a roller guard with discharge for friction-driven sweep conveyors. This disclosure limits the introduction of particulate matter into the interface between a driven roller and an inner surface of a continuous conveyor belt. The roller guard assembly is mounted between an upper belt portion and a lower belt portion near the drive roller and has a retaining wall member oriented at an angle that is neither parallel with nor at a right angle to the longitudinal axis of the belt and at such an angle that particulates carried on the inner surface of the lower belt portion are directed toward the discharge aperture in the first sidewall.
