Abstract:
cultural harvester comprising:a chassis extending, during work, transversely to the direction of forward travel;a harvester mechanism suspended moveably in the chassis by means of a suspension device;a drawbar connected to the chassis by means of a first articulation, the geometric axis of which is at least roughly vertical, said drawbar being intended to connect the harvester to a tractor vehicle;transmission members intended to transmit the motion from a source of motor power to the harvester mechanism and comprising, in particular:a first set supported by the drawbar and comprising at least a first drive shaft;a second set supported by the chassis and comprising at least one input shaft, the axis of rotation of which is, during work, directed at least roughly in the direction of forward travel;a coupling comprising a universal joint by means of which it is connected to the first drive shaft and another universal joint by means of which it is connected to the input shaft; wherein:the axis of rotation of the input shaft is offset with respect to the geometric axis of the first articulation connecting the drawbar to the chassis;the first drive shaft or the coupling are guided in rotation in a carrier member connected to the chassis by means of another articulation, the geometric axis of which is at least roughly vertical and at least roughly intersects the axis of rotation of the input shaft;an orientation member is connected between the carrier member and the drawbar.
