摘要： 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.

摘要： A root crop harvester 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. A feed belt feeds the mixture to a sorting zone where a separating device is arranged 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. At least one of the stripper belts has a discharge section with an incline smaller than 55° relative to the stripper plane and has in sections a non-round contour and a constant incline.

摘要： 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.
