A dirt removal and piling machine is ideally suited for use in cleaning and piling individualized and non-uniformly shaped workpieces, preferably sugar beets but also potatoes, other tuber crops, and even with aggregate rocks for a tilting receiving station. A further aspect of the present machine includes a workpiece unloading or receiving station which can tip sideways after a dump truck unloads the workpieces and longitudinally drives therethrough. In another aspect, the machine also includes a cleaning station having rotatable rollers, an underlying dirt conveyor and a moveable dirt dumping conveyor, hopper or bucket adjacent an end of the dirt conveyor and external to the rollers. Furthermore, another aspect of the machine includes an automatic and/or robotic sampling arm which is operable to remove a tuber crop workpiece sample and automatically package the sample after the sample has moved through a cleaning station.

Systems and methods for separating harvested crop product from twigs, dirt, dust, and other debris. A disk to be used in a harvester includes a first segment and a second segment and is configured to cooperate with adjacent disks axially mounted on a common rotational shaft, and radially cooperate with disks mounted on a parallel rotational shaft. The disks are used in a roller assembly or a harvester, and gaps between cooperating disks remain effectively constant during operation.

A sorting table for separating fruits from foreign bodies has at least one set of rollers revolvingly mounted in a frame. Each roller has a shaft with an axis orthogonal to the longitudinal axis of the frame. The sorting table has adjustment means intended to adjust the distance between the axes of rotation of the rollers according to the dimensions of the fruits to be selected.

A root crop conveyor is provided for cleaning and/or separating root crops, including at least two adjacent roller groups, each of which have at least two rollers, which each rotate about an axis of rotation and of which the axes of rotation form a roller group plane. An adjusting device is provided with at least one adjusting means. At least the rollers of at least one roller group are mounted, on one side, in at least one side part which interacts with the adjusting means, such that actuation of the adjusting means can give rise to movement of the at least one roller group plane relative to a frame in which the root crop conveyor can be arranged. wherein the adjusting device pivots the roller group plane. The rollers of a roller group are connected to one another via a scissors mechanism.

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.
