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.

A separating device is provided for separating a harvested mixture of root crops and admixtures. The separating device includes at least one conveyor element which circulates in operation at least for supplying the harvested mixture to a separation region, or for discharging the root crops from the separation region in a conveying direction. The separating device includes at least one fluid flow generator and at least one directing device for directing a fluid flow in a fluid flow direction to the separation region. The directing device is at least realized in at least one directing portion by the conveyor element itself.

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.

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.

The present invention provides an improved dust control system for removing debris and particulate matter from a fouled air stream. The system may be incorporated into crop harvesting equipment to eliminate the dust pollution generated by conventional harvesting equipment. The dust control system may use a multi-stage air filtering process that employs inertial separation techniques to eliminate particulate matter from the fouled air, without the need for water or electrostatic mechanisms to capture the fine particulates in the fouled air.

A root crop harvester is provided, including a feed conveyor device for conveying conveyable material consisting of harvested crop and additional materials in a feed conveying direction. The root crop harvester also includes a separating device having at least one separating element for separating the additional materials from the harvested crop. The separating device has a conveyable material sensor, which is coupled to a first EDP evaluation unit and, during operation, is directed toward the conveyable material, and which is intended for recording conveyable material data. The conveyable material sensor may be directed toward the feed conveyor device during operation. In addition, the conveyable material sensor may be an optical conveyable material sensor.
