A full floor sweep system having a skeletonized head section to facilitate removal of grain from a grain bin. The sweep system having an elongated body extending a length between an inward end and an outward end and having a leading side and a trailing side. The elongated body is connected to a pivot point at the center of the grain bin and is configured to rotate around the pivot point. An agitator is connected to the outward end of the elongated body and is configured to agitate grain as the elongated body rotates around the pivot point. The agitator includes an impeller that is connected to a shaft that extends through the elongated body. A scraper is positioned at the outward end of the elongated body and is configured to move grain into the path of the elongated body.

A lock-out pinion can be coupled to a center sump control shaft to rotate therewith. A lock-out slide can include a rack and a blocking cover. A lock-out guide can be coupled to the sump control housing and can form a guide channel. The lock-out slide can be received in the guide channel with the lock-out pinion drivingly coupled to the rack to move the lock-out slide along the guide channel from a lock-out position in which the blocking cover prevents rotation of the intermediate sump control shaft with the driving handle, to an unlocked position in which the blocking cover permits rotation of the intermediate sump control shaft with the driving handle, in response to manual rotation of the center sump control shaft in the center sump opening direction.

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.

A bin sweep auger unplugging system for unplugging a central unloading sump in a storage bin. The bin sweep auger unplugging system generally includes an auger having a driven shaft with auger fighting, a drive unit having a drive shaft, and a clutch connected between the drive shaft and the driven shaft. The clutch selectively transfers the rotation of the drive shaft to the driven shaft of the auger. The drive shaft includes a clump breakup component that breaks up the clump of granular material above the unloading sump when the drive shaft is rotated. The clutch is disengaged when breaking up a clump of granular material to prevent the rotation of the auger.

In one aspect, the disclosure describes an apparatus comprising an auger section having an auger and a drive unit containing a motor for driving the auger. A collector ring housing containing a collector ring is positioned between the auger section and the drive unit. In another aspect, the disclosure describes an apparatus for attachment to a floor grate. The apparatus includes a pivot stand attached to a top surface of the floor grate, the pivot stand defining a vertical pivot axis. A collector ring has a first stationary portion and a second rotatable portion, with the stationary portion attached to the pivot stand. A housing surrounds the collector ring, and the housing and second rotatable portion of the collector ring rotate together about the pivot axis.

A grain dryer unload system is presented that facilitates operation of a discharge system independent of a metering system. A motor connects to an axle that connects to the discharge system, which may be a drag chain, a belt or an auger. The axle also connects to a metering system. A clutch mechanism is connected to an end of the axle and is positioned between the discharge system and the metering system. When the clutch mechanism is in an engaged position, the motor simultaneously operates the metering system and the discharge system. However, when the clutch mechanism is in a disengaged position, the motor operates the discharge system while the metering system does not operate. This arrangement facilitates easier cleaning of the grain dryer without introducing the fines into the grain or a connected grain storage device.

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.

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.

A bin sweep auger unplugging system for unplugging a central unloading sump in a storage bin. The bin sweep auger unplugging system generally includes an auger having a driven shaft with auger fighting, a drive unit having a drive shaft, and a clutch connected between the drive shaft and the driven shaft. The clutch selectively transfers the rotation of the drive shaft to the driven shaft of the auger. The drive shaft includes a clump breakup component that breaks up the clump of granular material above the unloading sump when the drive shaft is rotated. The clutch is disengaged when breaking up a clump of granular material to prevent the rotation of the auger.
