Abstract: A grain bin unload conveyor trough can have a wall profile including a lowermost curved wall portion. Lower portions of a pair of side walls can be spaced laterally from each other at a first interior lateral width, and upper portions of the side walls can be spaced laterally from each other at a second interior lateral width that is greater than the first interior lateral width. A shelf portion of each side wall can extend laterally outwardly from the lower to the upper portion of the side walls. An auger hanger can extend laterally across the conveyor trough and can be supported on the shelf portions of the side walls. The auger hanger can extend down to hold an auger shaft of a grain bin unload conveyor auger in the conveyor trough centrally within the first interior lateral width between the lower portions of the side walls.

Abstract: A commercial hopper grain bin shell can be assembled on a concrete pad using jacks to successively support previously coupled side-wall panel rings above the concrete pad. The assembled shell can be supported above the concrete pad with the jacks while coupling a horizontal support beam around a bottom of the assembled commercial hopper grain bin shell. An uppermost ring of vertical support legs can be coupled to the horizontal support beam. An uppermost ring of hopper panels can be coupled to the horizontal support beam. The assembled shell and the vertical support legs previously coupled to the horizontal support beam can be successively supported above the concrete pad with jacks while coupling an additional ring of vertical support legs to the bottom of the previously coupled vertical support legs. An additional ring of hopper panels can be successively coupled to the bottom of the previously coupled hopper panels.

Abstract: An auger can be drivingly coupled to an input shaft of a wheel reduction gearbox. The wheel reduction gearbox can drivingly couple the input shaft to an output shaft of the wheel reduction gearbox. The output shaft can be drivingly coupled to a sweep end wheel. The sweep end wheel can include a plurality of tread brackets, a wheel plate, and an adjustable coupling corresponding to each of the tread brackets. Each adjustable coupling can selectively couple one of the tread brackets to the wheel plate in one of a plurality of radial positions. Each of the plurality of radial positions can correspond to the tread bracket being located at a different radial distance from a central axis of rotation of the wheel plate.

Abstract: An unload conveyor and a sweep conveyor can be positioned below and above a floor of the grain bin, respectively. A below floor gearbox and an above floor gearbox can be positioned below and above a sloped wall, respectively, of a sump. The sloped wall can be designed to shed grain toward a sump basin. A coupling shaft can extend through a non-circular sump shaft aperture in the sloped wall to couple the below floor gearbox to the above-floor gearbox. The coupling shaft can extend vertically. A pair of seal cover plates can form a horizontal wall extending perpendicular to the coupling shaft. The horizontal wall can have a circular sealing aperture therein and through which the coupling shaft extends. A washer can be provided adjacent the circular sealing aperture that can be free to move laterally with wobbling of the coupling shaft.

Abstract: A gearbox below a grain bin floor can have a shift coupling movable between a drive position and a neutral position. A control rod can be axially movable between a corresponding drive position and a corresponding neutral position. A pair of biasing members can be operably positioned between the control rod and the shift coupling to bias the shift coupling in opposite directions. The opposite biasing forces of the biasing members can act against each other to bias the control rod into the neutral positioning recess to retain the external shift coupling and the control rod in the neutral position and the corresponding neutral position, respectively. The opposite biasing force of the biasing members can bias the control rod into the drive positioning recess to retain the external shift coupling and the control rod in the drive position and the corresponding drive position, respectively.

Abstract: A storage bin may include a corrugated outer sidewall, a generally flat inner sidewall, and a first fastener. The corrugated outer sidewall may support a hoop tension provided by a material within the storage bin and may include a series of horizontally extending corrugations forming alternating grooved portions defining alternating circumferentially extending radially inner and outer ridges vertically spaced from one another along a vertical extent of the outer sidewall. The corrugated outer sidewall may define a first aperture. The generally flat inner sidewall may support the hoop tension, abut the radially inner ridges, and define a second aperture. The first fastener may extend through the first and second apertures and may couple the inner and outer sidewalls to one another.
