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 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.

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.

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.

An assembly includes a frame and a conveyor mat configured to transition between a retracted state in which the conveyor mat is disposed within a footprint of the frame, and a deployed state in which the conveyor mat is disposed at least partially disposed outside the footprint of the frame. The conveyor mat has a plurality of linkages, a plurality of rollers, a plurality of supports, and a plurality of axles. Individual axles couple to individual linkages of the plurality of linkages, individual rollers of the plurality of rollers, and individual supports of the plurality of supports together. A tensioning system is configured to control the conveyor mat transitioning between the retracted state and the deployed state.

A metal chip conveyor having an internal chip removal structure includes an endless conveyor belt. An accommodating room of a machine body is divided into an inner space and an outer space. Two sides of the conveyor belt assemble with chains each having chain links. Each chain link has a first opening facing the inner space and a second opening facing the outer space. A guiding block is arranged in the inner space. The guiding block has a bottom surface, a blocking face, and a guiding gap. The bottom surface faces to the conveyor belt. The guiding gap lies at one side of the blocking face and communicates with the chain links. Therefore, metal chips are stopped by the blocking face and are moved to the guiding gap, then drop to the outer space via the chain links.
