<p>The invention relates to a silage unloader fork comprising - a frame (2) equipped with parallel teeth (1) inscribed within a contour (1a), - a cutting device comprising a support (18) for a cutting member (19), - a first set of articulated levers (13, 20) forming a pantograph connecting the cutting device to a fixed axle (4) supported perpendicularly to the plane of the teeth (1) and at a specific distance from this, - a follower member (25) integral with the pantograph and interacting with a stationary guide track (27) homothetic with the contour of the teeth (1a), - a second set of articulated levers (25, 28, 30, 32) for the orientation of the support of the cutting member, forming with the pantograph (13, 20) a double articulated parallelogram. The follower member and one of the levers of the orientation set consist of a single part (25) articulated on the pantograph and mounted slidably on an arm (11) pivotable about the abovementioned fixed axle (4). <IMAGE></p> |
