Harvesting unit for a harvesting machine

A harvesting unit comprising:

• a chassis intended to be moved along rows of plants to be harvested, and
• a shaker system including at least one shaker device comprising:
• a drum operable to detach a crop from the plants, the drum comprising a drum shaft mounted for rotation on the chassis about a vertical axis and shaker organs mounted to the drum shaft;
• a rotational driving mechanism for the drum, the rotational driving mechanism comprising a driven body and a first driving device engaged with the driven body to steer rotation of the driven body about the vertical axis;
• and
• an oscillatory driving mechanism of the drum about the vertical axis, the oscillatory driving mechanism comprising:
• at least one eccentric module;
• a second driving device engaged with the at least eccentric one module to steer rotation of the at least one eccentric module;
• a mechanical member drivingly connecting the at least one eccentric module to the drum shaft and operable to transform the rotation of the at least one eccentric module into an oscillation of the drum shaft, the mechanical member comprising a window in which the at least one eccentric module is mounted, the mounting of the at least one eccentric module in the window being operable to transform the rotation of the at least one eccentric module into an oscillation of the mechanical member;
• and
• a planet shaft that is mounted for rotation on the driven body about a planet vertical axis, the at least one eccentric module being mounted to the planet shaft,
• wherein the at least one eccentric module is mounted for rotation on the driven body of the rotational driving mechanism,
• wherein the mechanical member is arranged to transmit the rotation of the driven body to the drum shaft, and
• wherein the at least one eccentric module is immobilized in a circumferential direction relative to the mechanical member inside the window.
