<p>1. Implement for cutting of silage blocks from a horizontal silo with especially one frame (1) equipped on its lower part with teeth (5) and at a certain distance above these teeth, with an arm (6) its outer end having a cutting device (7), said arm being articulated on a support (13) with which it can be moved in rotation in a nearly horizontal plane, a set of gearwheels comprising one gearwheel (33) integral with the frame (1), a second gearwheel (34) integral with the arm (6) and an intermediate gearwheel (31) free in rotation which is mounted on an axis housed in the walls of said support (13) at fixed distances in respect to the two other gearwheels (33 and 34), said intermediate gearwheel (31) intermeshing with these two other gearwheels (33 and 34) in order to make the arm (6) turn in the opposite direction to the direction of rotation of this support (13), characterized by the fact that a second intermediate gearwheel (32) free in rotation is mounted on a second axis (35) housed in the walls of the support (13) at fixed distances in respect to the two other gearwheels (33 and 34) and that the two intermediate gearwheels are situated on both sides of a line (A) passing through the geometric axes of rotation of the two gearwheels (33 and 34) and intermesh with the two gearwheels (33 and 34) in such a way that they share power to be transmitted.</p> |
