  • Patent number: 10271475
    Abstract: A machine for harvesting root crop has a lifting device that in a position of use on a harvest field lifts several rows of the crop with admixtures from the soil transversely to the travel direction in accordance with a lifting width. From the lifting device the loosened mixture of crop and admixtures is movable opposite to the travel direction by a first longitudinal conveyor and is transferred onto a second screening belt conveyor. Between longitudinal conveyor and screening belt conveyor, a transfer zone is defined with belt overlap. The first longitudinal conveyor in the conveying direction together with the upstream lifting device forms a module that is movable in transverse direction of the machine relative to the second screening belt conveyor. This module, relative to the common transfer zone, can be moved at least sectionwise into a position of lateral spacing relative to the second screening belt conveyor.
