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.

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 system for opening a lid of a bin comprises a guide channel plate comprising an elongated member, a first guide channel comprising a first slot formed within and along the length of the guide channel plate, and a second guide channel comprising a second slot formed within and along the length of the guide channel plate and parallel to the first guide channel slot. A block plate fits within the first and second guide channels and is secured by a block plate clamp. The block plate connects to a linear actuator that is secured to a support member of the bin. A slide block fits compressively within the first and second guide channels thus securing a flexible link assembly and wherein the slide block connects to the linear actuator. A connector plate allows connecting and disconnecting of the linear actuator.

The invention is directed broadly to a filter for a bin storing agricultural material, the filter comprising; a rigid perimeter frame supporting a grate within the frame; and a plurality of legs spaced about the perimeter frame, wherein the filter, in use, is located within the bin and positioned to substantially cover an outlet of the bin, the plurality of legs in direct contact with the bin so as to transmit vibrations from the bin to the filter, the agricultural material within the bin traversing the grate as it exits the bin.

A bin sweep system for a bin having a floor surface and a central well may comprise a center post defining a common center and a sweep assembly configured to move across the floor surface of the bin and having an inboard end and an outboard end. The sweep assembly may comprise at least two sweep segments including a first sweep segment and a second sweep segment, with the first sweep segment being located toward the inboard end and the second sweep segment being located toward the outboard end. At least one of the sweep segments may be movable about the center post substantially independently of another of the sweep segments.

A modular storage bin sweep system utilizing paddles to sweep particulate matter across a floor may comprise a sweep assembly including at least two units connectable together. The assembly may comprise a plurality of interconnected paddles, a power unit configured to the paddles, a drive unit configured to move the sweep assembly with respect to a surface of the bin below the sweep assembly. In some embodiments, a traction enhancement structure may increase traction of the drive unit on the floor. In some embodiments, a pivot unit is configured to permit a degree of pivotability of the axes of the units with respect to each other, and may be combined with a drive unit. In some embodiments, the power unit includes a rotary electrical power transfer structure configured to transfer electrical power to the power unit when rotating in the bin.

In one aspect there is provided a hopper, for use with a grain bin having a gate assembly with bolts or flanged edges. The hopper comprises a concave shape, a bottom, and hopper walls forming a chamber with an open top for receiving granular materials from the gate assembly. A mounting member is positioned on the hopper walls adjacent the open top to mount the hopper from the gate assembly's bolts or flanged edges.

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.

The invention is directed broadly to a filter for a bin storing agricultural material, the filter comprising; a rigid perimeter frame supporting a grate within the frame; and a plurality of legs spaced about the perimeter frame, wherein the filter, in use, is located within the bin and positioned to substantially cover an outlet of the bin, the plurality of legs in direct contact with the bin so as to transmit vibrations from the bin to the filter, the agricultural material within the bin traversing the grate as it exits the bin.
