A system protects an outlet of a pneumatic conveyor. The outlet has a horizontal section. The system comprises a deflector for protecting the horizontal section, and sets of stanchions therefor respectively attached to clamp assemblies mounted on the horizontal section. The deflector comprises angled walls, a plurality of crossbeams interconnecting the angled walls for reinforcing the deflector, and an end flange. Each stanchion has a foot. Each clamp assembly comprises two equal halves, fasteners joining together the equal halves, and a flange for each equal half perpendicular thereto. The system further comprises fasteners each attaching one foot to one flange, respectively.

Material is removed from a storage silo that has a conveyor outlet, a system for supporting the outlet within the silo comprising removable legs mounted in deployed positions, and a sweep comprising bumpers. The material is extracted until one leg is accessible out of the material, which is then removed from the deployed position thereof. The sweep is then operated to continue extracting more material until one bumper thereof bumps into another of the deployed legs. The sweep is then stopped, and that other leg is also removed from the deployed position thereof. This sequence of operating and stopping the sweep, and removing each deployed leg, is continued for each of the deployed legs until all of the legs are removed from the deployed positions. Each removed leg may be placed onto the supporting system in a stored position thereof. The sweep is then operated to continue extracting more material.

A bin wall cleaner for a sweep conveyors and augers for removing residual grain located near the bin wall out of reach of the sweep conveyor and providing sweep coverage for non-uniform bin walls. The bin wall cleaner has a grain engagement member that extends outwardly from the distal end of the sweep. A biasing member maintains the grain engagement member extended toward the bin wall. A wall engagement member is attached to the grain engagement member to ensure the bin wall cleaner tracks with the bin wall. The grain engagement member extends by pivoting or telescoping at least one blade.

The disclosure describes an apparatus including a bin sweep arm, a floor support in contact with a floor surface, and a vertical adjustment assembly positioned between floor support and the bin sweep arm and connected to the floor support and the bin sweep arm, wherein the vertical adjustment assembly automatically raises the bin sweep arm off the floor surface and automatically lowers the bin sweep arm to the floor surface in response to changes in weight disposed on the bin sweep arm.

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.

The invention relates to a grain sweep (1) for use on a floor comprising at least a first drive means (2), an elongated frame (3) comprising a rotatably arranged inner end (4) and an outer end (5), a drive wheel (6) adapted to rotate the elongated frame (3) around said inner end (4), and a grain moving means (7) adapted to move grain. The grain sweep (1) further comprises at least one resilient member (8) arranged at either said inner (4) or outer end (5) of said elongated frame (3), wherein the resilient member (8) allows the elongated frame (3) to move from said upper position towards a lower position when pressure is applied upon the elongated frame (3), and wherein the resilient member (8) allows the elongated frame (3) to move back towards said upper position when the pressure is removed.

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 flighting, 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.

A sweep system is presented for a grain bin. The sweep system includes 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. In one or more embodiments, a tail section of the sweep system is located as the outward end of the elongated body. In one or more arrangements, a track-driven drive system is positioned in the tail section. The track-driven drive system has a continuous track formed by a continuous chain and a plurality of paddles connected thereto. The track-driven drive system is configured to move the outward end of the elongated housing around the grain bin thereby facilitating emptying of grain from the grain bin by the sweep system.
