A crop cart cleaning and unloading system for cleaning debris such as dirt and rocks from a crop as the crop is being transferred between a hopper of a crop cart and a transport vehicle. The crop cart cleaning and unloading system generally includes a hopper for receiving a crop such as potatoes. The hopper transfers the crop onto a cleaning bed on which the crop is cleaned of debris, with the debris falling underneath the cleaning bed. The crop is conveyed across the cleaning bed as it is cleaned, with the cleaned crop being transferred from the cleaning bed onto an unloading conveyor. The unloading conveyor then transfers the cleaned crop to another location to be discharged, such as directly into a transport vehicle for further transport and processing.

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.

The invention relates to a root crop harvester in the form of a potato harvester (1), comprising a lifting device (2), from which a crop material (E) and also a mixture (G) comprising clods, weeds and similar admixtures (B) can be displaced in the region of screen belts (3) which are arranged downstream thereof. According to the invention, the mixture (G) lying on one of the feed belts (4) reaches a sorting zone, where the crop material (E) is sorted by means of a separating device (6) that is arranged above the feed belt (4) and is acting on the mixture (G) transversely to the direction of feed of the feed belt, in such a manner that two scraper belts (8, 9), which are circulating in the same direction in a scraping direction (7, 7), capture the crop material (E) by means of respective scraper elements (10, 10; 11, 11), and feed said crop material in two adjacently arranged scraping planes (12, 13) to a sorting belt (14) that is arranged downstream thereof. Admixtures (B) that remain on the feed belt (4) can be discharged in a discharge direction (5), which is preferably offset by about 90 from the scraping direction (7, 7), wherein the two scraper belts (8, 9) are in each case individually adjustable in the region of at least one of the supporting devices (17, 18) which hold in each case said scraper belts.

A harvester includes a separator configured to separate a cut crop into a billet material and extraneous plant matter, a billet loss sensor configured to generate a first signal indicative of the amount of billet material that is lost and unharvested at the separator; a trash sensor configured to generate a second signal indicative of the amount of the extraneous plant matter that is harvested from the separator, and a control unit configured to, based at least partly on the first signal and the second signal, determine a preferred ground speed of the harvester and/or a preferred separator speed of the harvester.

A potato harvesting machine has a lifting device picking up a mixture of crop and admixtures. Screening belts downstream of the lifting device transport the mixture away from the lifting device and a feed belt feeds the mixture to a sorting zone. A separating device is arranged in the sorting zone above the feed belt. A sorting belt is arranged downstream of the separating device that has first and second stripper belts circulating in a stripping direction and provided with stripper elements. The stripper elements act on the crop transverse to a feed direction and supply the crop to the sorting belt. The admixtures remain on the feed belt and are discharged in a guiding direction angled to the stripping direction. First and second support devices hold the first and second stripper belts. The first and second stripper belts are individually adjustable at the first and second support devices.
