  • Patent number: 11937551
    Abstract: A twine knotter for a bale press for forming two sequential knots for holding together a tying agent surrounding a crop bale includes a knotter frame and a knotter hook supported rotatably in the knotter frame and provided for knotting together ends of the tying agent. A holding arrangement has a twine holding disk rotatably supported at the knotter frame and conveying temporarily two tying agent strands of the tying agent. A knotter disk that is rotatingly driven is provided with a first drive element driving the knotter hook and a second drive element driving the twine holding disk. A stripper lever is provided to strip off knots from the knotter hook. A knife blade is provided to cut through tying agent strands. The twine holding disk upon rotation is guided along the knife blade so that the tying agent strands are cut through upon passing the knife blade.

  • Patent number: 11910757
    Abstract: A knotter hook for a twine knotter has a stationary clamping wing and a pivotable clamping wing, Stationary clamping wing and pivotable clamping wing have an extension component in a same spatial direction. The pivotable clamping wing has a projection projecting toward the stationary clamping wing. The pivotable clamping wing is pivotable reversibly from a closed state into an open state. A free end of the pivotable clamping wing in the open state is spaced apart farther from the stationary clamping wing than in the closed state. The pivotable clamping wing is laterally displaced relative to the stationary clamping wing at least in sections so that the pivotable clamping wing is arranged adjacent to the stationary clamping wing and below the pivotable clamping wing a free space is formed. The free space extends in the closed state opposite to the spatial direction beyond the projection.

  • Patent number: 11641793
    Abstract: A mowing machine has a cutterbar oriented transverse to a travel and working direction of the mowing machine and provided with first and second ends spaced apart from each other in longitudinal direction. First cutting members are rotatably mounted on a top side of the cutterbar and rotatably driven about a vertical axis by a drive assembly within the cutterbar. A joint and drive assembly is connected to the first end of the cutterbar. A lateral cutterbar section is connected to the joint and drive assembly and has a second cutting member driven by the joint and drive assembly. The joint and drive assembly has first and second holding elements mounted relative to each other such that pivoting of the lateral cutterbar section in a cutterbar plane of the cutterbar is enabled. The first and second holding elements are arranged in planes positioned at a minimal spacing above each other.

  • Patent number: 11089735
    Abstract: A baler for agricultural crop has a pressing channel and a needle rocker pivotably arranged at the pressing channel about a rocker pivot axis arranged in a plane that is orthogonal to the longitudinal center axis of the pressing channel. A drive arrangement connected to the needle rocker pivots the needle rocker relative to the pressing channel. The needle rocker has tying needles that are moved through the pressing channel when the needle rocker is pivoted. The drive arrangement has a drive element, rotatably supported about a drive axis of rotation; a coupling device pivotably supported about a coupling pivot axis positioned stationarily relative to the pressing channel; and a drive lever with a first end eccentrically connected to the drive element and a second end connected to the coupling device. The coupling device is connected to the needle rocker spaced from the rocker pivot axis of the needle rocker.
