  • Patent number: 6925790
    Abstract: A harvesting apparatus for harvesting corn or other such stalked vegetation includes at least one circulating endless conveyor for gathered plants, which forms an area at an end thereof for delivery of the plants to an inlet opening of a further processing apparatus. The endless conveyor includes conveyor links articulated to one another and at least one cutting plane comprising outwardly pointing cutters and having above it at least one holding plane for holding the cut stalks and including lower, outwardly-pointing holders. The endless conveyor is constructed such that a front side thereof, facing the cutters and holders, is of a substantially closed configuration.

  • Patent number: 6837034
    Abstract: Harvesting equipment (1) for harvesting corn or similar stalk-like harvested products, the harvesting equipment (1) having at least one link chain (4; 5), which is provided with holding means for the cut-down harvested products (3), and has a tight side (4a; 5a) which can be moved, when in use, transversely to the driving direction (F) of the harvesting equipment (1), is constructed so that the extent (T) of an element (14, 15) of the link chain (4; 5), measured in the revolving direction (U1; U2), essentially corresponds to a whole number divider of a standard distance between rows (3a) of harvested products (3) cultivated, in a standardized manner.

  • Patent number: 6668532
    Abstract: A harvesting machine for harvesting corn and similar crops on stalks has at least one circulating endless conveyor for engaging a crop, wherein the endless conveyor forms a crop feed area for feeding the crop to an inlet opening of a processing device for further processing the crop. The endless conveyor has a lower cutting plane for the crop with outwardly extending conveying and guiding elements and at least one cutting blade arranged below the conveying and guiding elements. The cutting blade has a stepped configuration and, viewed in a running direction of the conveying and guiding elements, has cutting segments. Each cutting segment has a cutting edge and extends at a slant outwardly relative to a circulating path of the conveying and guiding elements. The cutting blade has cutting segment steps positioned between two neighboring ones of the cutting segments, respectively.
