A roll segment is provided for a roll of an agricultural crop transporting and/or cleaning device which has a plurality of rolls, which are oriented at least substantially transversely to the transport direction and which are preferably formed as spiral rolls in succession in the transport direction, and via which, during operation, the crops are transported for cleaning and/or transport purposes. The roll segment has a longitudinal axis which, during operation, corresponds to a rotation axis and, for the purpose of forming the roll with at least one further roll segment extending in the direction of the longitudinal axis during operation, has at least at one end at least one first connection element which is designed for connection to a further connection element of the further roll segment.

A shock-absorbing conveyor boom includes a proximal portion and a distal portion, hingedly connected to the proximal portion, the proximal and distal portions supporting a laterally flexible endless conveyor belt. The distal portion is pivotal in a generally horizontal plane, and is biased toward longitudinal alignment with the proximal portion, whereby physical shock applied to the distal portion can be absorbed by lateral deflection of the distal portion.

Universal belted chain including a first belt, a second belt, a first rod, a first fastener and a second fastener. The first belt has a first upper surface and a first lower surface. The first lower surface has a first channel formed therein. The second belt has a second upper surface and a second lower surface. The second lower surface has a second channel formed therein. The first fastener attaches the first rod to the first upper surface by extending the first fastener through the first belt. An end of the first fastener opposite the first rod is recessed in the first channel with respect to the first lower surface. The second fastener attaches the first rod to the second upper surface by extending the second fastener through the second belt. An end of the second fastener opposite the first rod is recessed in the second channel with respect to the second lower surface.

A digger-shaker-inverter for harvesting root plants includes a frame and a row unit. The row unit includes a first belt driving assembly and a second belt driving assembly. The first belt driving assembly includes a first carrying belt that grips a first side of a vine and a fixed bracket that supports the first carrying belt. The second belt drive assembly include a second carrying belt that grips a second side of the vine, and an adjustable bracket that supports the second carrying belt and adjust to control a distance between the first carrying belt and the second carrying belt.

A piler conveyor system for screening debris such as tare dirt from materials such as beets as the materials are conveyed across a piler. The piler conveyor system generally includes a frame supporting an upper conveyor and a pair of lower conveyors. The upper conveyor is adapted to receive materials such as beets. As the materials are conveyed by the upper conveyor, debris such as tare dirt or the like will fall through screening openings in the upper conveyor and onto the lower conveyor. The lower conveyor may then dispense the debris through a debris opening. The materials will drop off the end of the upper conveyor and fall onto the second lower conveyor, which will convey the screened materials to be dispensed.

Apparatus for cleaning narrow root crops including a roller device with two rotatable rollers forming a separating crop inlet, a separating track, a coarse material outlet, a fine material outlet, and a roller gap, and a conveyor downstream of the roller device. The separating track is formed by the top of the rollers and the fine material outlet is located below the roller gap. The coarse material outlet is at the end of the separating track opposite the separating material inlet. The roller gap is large enough to allow the narrow root crops to pass through to the fine crop outlet and small enough to retain coarse material that has a minimum dimension greater than the maximum root diameter, and transport it to the coarse material outlet. The conveyor is below the roller gap at the fine material outlet and receives all narrow root crops passing through the roller gap.
