An apparatus for conveying root crops is provided. The apparatus includes a carrying device which circulates in a circulation direction during operation. The carrying device partly forms at least one receiving region and carries the root crops. At least one transverse separating device extends at least partially in a transverse direction. This delimits the receiving region in the circulation direction. From the outside, the receiving region adjoins an interior space which extends inside an interior space surface. The interior space surface extends parallel to the transverse direction and in side view runs exclusively in the circulation direction. At least one protruding part of the transverse separating device is arranged, in side view, outside the interior space.

A conveying device is provided for an upwardly oriented, in particular vertical, conveyance of turnips or other root crops in harvesting machines. A conveyor belt with at least two lateral conveyor belt portions is moved in a conveying direction during operation. Between the conveyor belt portions is defined a particularly planar conveyor belt surface, and at least one carrier unit which projects from the conveyor belt surface and is supported by the conveyor belt. The carrier unit delimits a receiving space extending on both sides of the conveyor belt surface. The part of the receiving space which is arranged on the side of the conveyor belt surface which is opposite the carrier unit is formed by at least one detachably fastened pocket module and harvesting machines for turnips or other root crops having a conveying device.

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.

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.

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 control system for use on a peanut harvester using a conveyor to elevate and relocate the peanut pods and attached plant material. The control system inputs the ground speed in the direction of travel and the conveyor speed, and outputs to an electronic flow control valve that is part of a hydraulic circuit between a hydraulic motor that drives the conveyor and a connection point that provides hydraulic power to the hydraulic motor. The control system uses an algorithm that compares the ground speed and the conveyor speed and varies the output to the flow control valve so that the conveyor speed is maintained at a defined percentage of ground speed. The defined percentage of ground speed is a user-controlled variable that can be adjusted on the go through the user interface portion of the control system.

A method is provided for controlling the operation of a machine for harvesting root crop. At least one optical image-capturing unit captures at least one test image of harvested material comprising root crop which is moved along relative to a machine frame by means of at least one conveyor element. A conveying speed of the conveyor element is set on the basis of a test data set which is generated using the test image or formed by means of the latter. An evaluation device generates, on the basis of the test data set, a conveying speed signal, independent of a speed of the harvested material, for setting the conveying speed.
