A harvesting device includes a support defining an uprooting position of the harvesting device, and an uprooting section comprising at least two uprooting units, each uprooting unit having at least one uprooting element, each uprooting unit being adapted to uproot root crop. At least one of the uprooting units is mobile with respect to the support between an active position and an inactive position, the active position being a position in which the uprooting unit is able to uproot beet crop in a field having a field surface when the harvesting device is in the uprooting position, the inactive position being a position in which the uprooting unit is unable to uproot beet crop in the field when the harvesting device is in the uprooting position.

A method of detecting a potato virus in a crop image depicting at least one potato plant includes storing the crop image in a memory, identifying a first region of the crop image depicting potato plant leaves, identifying a plurality of edges within the first region, determining whether an image segment of the crop image within the first region satisfies one or more leaf creasing criteria symptomatic of leaf creasing caused by the virus based on the edges that are located within the image segment, determining whether the image segment satisfies one or more color criteria symptomatic of discoloration caused by the virus, and determining whether the segment displays symptoms of potato virus based on whether the image segment satisfies one or more of the leaf creasing criteria and the color criteria. A system and computer readable medium are also disclosed.

Screening belt unit is provided for a harvesting machine or harvested material transport device, and in particular for a root crop harvester or root crop transport belt, and for screening extraneous material out of a mixture of harvested material and extraneous material. A screening belt has at least two endless carriers, preferably in the form of carrier belts or chains, between which screening bars are arranged in a direction transversely to the conveying direction. The screening bars forming a plurality of screening bar units that comprise in particular in each case at least two screening bars. At least a part of the screening bars is fixed so as to be movable relative to the endless carriers. The screening belt unit has a positioning means which is arranged at least partially along the screening belt and acts on the movable screening bars. In the screening zone S, as seen in the screening direction, a spacing A in the conveying direction F of successive screening bars is defined and in particular settable in a variable manner, and associated flap unit.

The invention relates to a ring elevator (2) for lifting root crops (8) in a root crop harvester (1), comprising: a first and a second pair of endless carrying strips (3, 4), each pair arranged in parallel and drivable over a closed path; first and second parallel transverse elements (5) attached between and to respectively the first and second strips (3, 4); flexible support elements (7), each attached to a first transverse element (5) and to a second transverse element (6);
the first strips (3) being arranged around the second strips (4), at a distance, which, varies along the paths between a minimum distance (d.sub.min) and a maximum distance (d.sub.max), and in an ascending part (32) equals a carrier distance (c), such that the flexible support elements (7) form baskets for receiving the root crops (8), wherein the useful volume (V.sub.u) in the baskets (7) takes up at least 50% of the total volume (V.sub.t) delimited by the transverse elements (5, 6).

This determining apparatus (62) for determining a datum during the harvesting of fruit (4), for example, sugar beets, comprises a fruit flow apparatus (50) for the treatment of a flow (52) of harvested fruit, a sensor device (64) for detecting a raw datum of the flow, a determining device (66) connected to the sensor device for determining a datum of the flow based on the raw datum. The datum is a quality datum or a yield datum of the flow. The determining apparatus is designed to output a signal, which corresponds to the quality datum or the yield datum. The quality datum or the yield datum reflects an item of information about a net yield of the harvested fruit.
