Combine harvester with automatic hydraulic and electric header coupling

An agricultural machine comprising a feeder (1) and a detachable header (2), the feeder comprising a means for lifting up the header from the ground or from a trailer, the lifting means comprising a carrying structure (3) for supporting a beam (4) or the like located on the header, wherein

• the feeder (1) further comprises at least one rotatable cam (15) located lower than the carrying structure (3), and actuating means (10) for rotating the cam (15) about an axis (14), wherein the cam and actuating means are configured to:
• maintain the lower portion of the header (2) at a distance from the feeder, after the header has been lifted from the ground or trailer, by extending the cam (15) towards the header, and
• gradually reduce the distance between the feeder and the header, by rotating the cam (15) away from the header, the header being provided with a support surface (17) that the cam contacts during at least a part of its rotation,
• the feeder (1) further comprises at least one first hook (16), configured for rotation by said actuating means (10) about said axis (14), whilst maintaining a fixed relative position with respect to the cam (15), said position being such that the hook (16) rotates towards the header while the cam moves away from the header, so that the hook thereby grips a bar or pin (18) located on the header, thereby securing the header to the feeder;
• and
• the agricultural machine is provided with a coupling mechanism (20) for automatically establishing a hydraulic and/or electric coupling between the feeder (1) and the header (2), said mechanism comprising a first coupling part (21) mounted on the header (2), and a second coupling part (22) mounted on the feeder (1), the coupling parts being configured so as to automatically interlock and thereby establish the hydraulic and/or electric coupling, said interlock being actuated by the reduction of the distance between the feeder (1) and the header (2).
