A transfer tail assembly for use with a conveyor assembly that adjust the tension in the conveyor belt. The transfer tail assembly includes a pair of adjustment brackets that are each movable along a conveyor axis and support an end roller. The movement of the adjustment brackets and the end roller adjust the tension in the conveyor belt. A spiral cam is positioned such that rotation of the spiral cam causes movement of the end roller along the conveyor axis. A drive pin of the adjustment bracket moves along a spiral cam contact surface. The end roller is pivotable relative to the conveyor frame to release tension on the conveyor belt. The final position of the end roller can be adjusted using a pivot limiting bar.

A drive roller assembly for a conveyor system includes a drive roller having a longitudinal axis, the drive roller having a roller body and a shaft. A support structure rotatably supports a second axial end portion of the shaft and a drive for rotatably driving the drive roller. A first axial end portion of the shaft and the drive are rotatably coupled in an axially engaged condition in which the drive roller is in rotatable engagement with the drive and in which the drive is axially releasable. The support is configured and adapted to be detachably attached to an attachment portion of the support structure to maintain the drive roller rotatably supported when attached and to allow the drive roller to be removed from the support structure when detached.

A conveyor construction for a continuous belt conveyor. The conveyor includes a conveyor frame assembly constructed from a plurality of separate extruded and joined frame sections. The frame assembly can include a pair of side frame extrusions joined to a center frame extrusion by a pair of attachment rails. The conveyor construction further includes a series of spindle mounting assemblies that support a tensioning spindle on opposite ends of the conveyor frame. Each of the spindle mounting assemblies includes a gear rack and a pinion head that is rotatable to move the gear racks. The gear racks contact one of a pair of head plates that support the tensioning spindle relative to the frame.

A conveyor employs an infeed assembly and outfeed assembly, each comprising a nosebar assembly that may be mounted to a conveyor frame to transition a conveyor belt between a returnway and a carryway. The outfeed assembly further includes a drive sprocket and a limiter to ensure engagement of drive elements on the conveyor belt with the drive sprockets. A limiter plate ensures proper placement of the limiter relative to the drive sprocket. The infeed assembly and outfeed assembly components may be easily mounted to and removed from the conveyor frame to facilitate replacement, cleaning or maintenance.

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.

A conveyor employs an assembly at a drive end having a position limiter assembly configured to accommodate flights in a conveyor belt while ensuring proper engagement between the conveyor belt and a drive. The end assembly includes opposing end plates, a drive extending between the end plates and a position limiter assembly extending between the end plates below the drive for ensuring proper engagement of a conveyor belt with the drive. The position limiter comprises a series of spaced apart rollers mounted to and spaced from a mounting bar extending between the end plates. Roller mounting arms connect the rollers to the mounting bars.
