A wet sand delivery and conveyor apparatus ships wet proppant from a sand mine wet plant to a well fracturing site and delivers the wet proppant directly to the well site. The wet sand delivery and conveyor apparatus comprises a multi-container support frame, which is mounted on a trailer bed, a plurality of containers mounted to an upper portion of the frame, and a conveyor belt mounted on the frame below the plurality of containers and positioned to receive proppant released in a gravity pour from the containers onto the conveyor belt. An auger mounted near an end of the conveyor belt is also provided to transfer sand from the end of the trailer bed to a position extending diagonally upward and away from the trailer bed to drop sand into a vessel or sand deposit site positioned underneath an upper end portion of the auger.

A screw conveyor assembly includes a first screw conveyor with a first housing and a first conveyor screw arranged therein, a second screw conveyor with a second housing and a second conveyor screw arranged therein, a transition housing to which the first housing and the second housing are connected forming a transition angle, and a runner disposed in the transition housing and arranged to conduct material being conveyed from the first conveyor screw to the second conveyor screw. The first conveyor screw is arranged upstream of the second conveyor screw. An additional conveyor element is disposed on a helix of the first conveyor screw, such that the helix is directly adjacent to the transition housing.

A sweep auger system having a driveshaft with auger flighting and a backboard extending a length from an inward end to an outward end. An input of a gearbox is connected to an outward end of the drive shaft and a sweep wheel having a plurality of notches, arms and feet is connected to an output of the gearbox. A drive shield is placed around a rearward side of the sweep wheel that forms a channel that is configured to capture grain agitated by the drive wheel. A guide plate is connected to the gearbox and covers a portion of the gearbox. The guide plate angles from an upper outward edge downward and forward to a lower inward edge that is configured to urge the grain captured within the channel of the drive shield to move in front of the sweep auger system reducing grain left in the grain bin.

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 material-conveying system comprising a conveyor for conveying material to a bin and a conveyor positioning system associated with the conveyor. The conveyor positioning system comprises a processor for positioning the conveyor relative to the bin. The conveyor comprises a spout and the bin comprises an opening. The conveyor positioning system positions the spout of the conveyor over the opening of the bin. The conveyor positioning system in one implementation comprises a Global Navigation Satellite System-Real Time Kinematic (GNSS-RTK) positioning system that includes a fixed base station and a GNSS receiver on the conveyor.

A material-conveying system comprises a main conveyor for conveying material, a swing conveyor for conveying the material to the main conveyor and a processor for controlling a speed of the swing conveyor based on a feedback signal. The feedback signal may be indicative of a speed of the swing conveyor and/or a speed of a main conveyor. The feedback signal may be indicative of material level, belt slippage, flow rate, belt angle and/or material rollback.

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 sweep auger apparatus includes an attachment plate having a first and second sides. The first side has attachment features to attach the attachment plate to mobile equipment. A first rotatable shaft is secured to the second side of the attachment plate. A central axis of the first rotatable shaft extends in a first direction. A first motor is connected to the first rotatable shaft to cause the first rotatable shaft to rotate. An auger support member is connected to the first rotatable shaft so as to rotate with a rotation of the first rotatable shaft. A second rotatable shaft is secured to the auger support member, and a central axis of the second rotatable shaft extends in a second direction that is transverse to the first direction. A second motor is connected to the second rotatable shaft to cause the second rotatable shaft to rotate, thereby rotating an auger.
