Baler

A baler for agricultural crop, the baler comprising:

• a pressing channel comprising a longitudinal center axis;
• a needle rocker pivotably arranged at the pressing channel about a rocker pivot axis arranged in a rocker pivot axis plane that is orthogonal to the longitudinal center axis of the pressing channel;
• one or more drive arrangements operatively connected to the needle rocker and configured to pivot the needle rocker relative to the pressing channel;
• the needle rocker comprising one or more tying needles that are moved through the pressing channel when the needle rocker is pivoted;
• the one or more drive arrangements comprising:
• a drive element, rotatably supported about a drive axis of rotation;
• a coupling device consisting of a first coupling lever and a second coupling lever, wherein the first coupling lever and the second coupling lever are connected pivotably to each other about a first coupling pivot axis, wherein the first coupling lever is pivotably supported about a second coupling pivot axis so as to pivot about the second coupling pivot axis, wherein the second coupling pivot axis is positioned stationarily relative to the pressing channel;
• a drive lever comprising a first end eccentrically connected to the drive element, wherein the first end of the drive lever is rotatably connected to the drive element so as to be rotatable relative to the drive element about a drive lever axis of rotation passing through the drive element, wherein the drive lever further comprises a second end rotatably connected to the first coupling lever about a drive coupling pivot axis, wherein the drive coupling pivot axis is positioned at a distance from the first coupling pivot axis and at a distance from the second coupling pivot axis,
• wherein the second coupling lever is connected to the needle rocker at a distance from the rocker pivot axis of the needle rocker;
• wherein the rocker pivot axis, the drive axis of rotation of the drive element, the drive lever axis of rotation passing through the drive element, and the coupling pivot axis are arranged parallel to each other and are spaced apart from each other, respectively.
