  • Patent number: 9198357
    Abstract: A pick-up device, usable by an agricultural machine, includes a frame and first and second units. The first and second units each include a displacement device, are arranged beside each other and a small distance apart, are connected directly to the frame by respective first and second articulations having first and second distinct axes directed in a direction of advance, include respective first and second pick-up rotors rotatable about third and fourth axes, and are connected to one another by a guidance device. The first and third axes are in a same seventh plane, the second and fourth axes are in a same eighth plane. A stop mechanism defines two work end positions of the first and second units with respect to the frame, between which they can pivot freely within a limited range, and remain connected to one another regardless of their position between the work end positions.

  • Publication number: 20140137531
    Abstract: A pick-up device, usable by an agricultural machine, includes a rotating part including at least one support arm, to which are attached raking and picking up tools and which is configured to pivot about a rotation axis with respect to the rotating part by at least first and second bearings, the at least first and second bearings each including an outer ring rigidly fastened to the rotating part, and with respect to which outer ring the support arm can pivot about the rotation axis. The first bearing includes an inner ring configured to pivot about the rotation axis with respect to the outer ring and rigidly fastened to the support arm. A stop mechanism connects the inner ring to the outer ring, and limits displacement of the support arm with respect to the rotating part in a direction substantially parallel to the rotation axis to a small or nil value.
