<p>1. A reaping-conditioning machine of the type comprising a cutting bar (4) above and towards the rearward part of which is disposed a rotor (8) provided with teeth or fingers (11), rotating about a horizontal axis which is transverse with respect to the direction of forward movement of the machine, and combined with a conditioning hood (12) which is held only at its front and rear transverse edges, the hood surrounding a portion of the circumference of the rotor (8) to guide the crop products which are picked up by the rotor after they have left the cutting bar, to cause them to pass above the rotor for them to be projected on to the ground in the form of a windrow to the rear of the machine, the hood (12) being adjustable by way of its mounting points in such a way that one or both transverse edges can be displaced with respect to the periphery of the rotor, characterised in that the hood (12) which is of resiliently deformable sheet metal is held at at least one of its transverse edges by a rapid adjusting means comprising an eccentric (15) which is pivotally mounted on at least a fixed portion of the machine and which is positively connected to said transverse edge of the hood and the angular position of which is adjustable in order to modify the profile of the conditioning hood by resilient deformation of the sheet metal, and thus the position of the hood with respect to the rotor (8).</p> |
