The invention relates to a device for mechanical cutting and transport of silage, consisting of a support frame attached to a tractor, a rake arranged on the support frame with horizontally running prongs and one above the rake on the support frame movably arranged and the cutting element driven by the power take-off shaft of the tractor.

In a known device of this type, the cutting element consists of a saw chain or prongs arranged on a beam at the ends of two arms pivotable about horizontal pins is attached. As a result, the cutting element becomes vertical during the cutting process Starting position pivoted on a quarter of a circle into a horizontal lower end position. While fi.s this pivoting movement, however, has to be carried out by the beam carrying the cutting element, the pivoting arms and the drive elements are forced into the silage as a result of this according to the invention oelöst "doß the cutting organ straight up and is movable downwards. consists of a rectangular frame or box with at least two neighboring ones Lower edges carry a cutting unit with cutting edges directed downwards.

Each cutting unit preferably consists of two mechanically driven, reciprocating back and forth, knives serrated in a manner known per se.

The yra "cr of the rake is preferably in upright Rails of the support frame moved up and down, by means of chains or the like Frame or box hung and is in the support frame lockable.

The drive of the cutting units is advantageously carried out via a on the lower crosspiece of the support frame Fixed angular gearbox that can be coupled to the PTO shaft of a tractor, one parallel to the support legs running shaft, one on this shaft can be moved up and down, but twisted »An angular gear, a shaft mounted on the frame or box, attached to this shaft Eccentric discs, lifting rods and levers.

In the drawing, an exemplary embodiment is shown. It shows

Apparatus according to claim 1, characterized in that the drive of the cutting units (2) one attached to the lower transverse web (10) of the support frame, one with the PTO shaft Tractor's couplable angular gear, one parallel to the support frame legs (9) Shaft (23), a second one that can be moved up and down on this shaft, but is non-rotatable Angular gear, a shaft (3) mounted on the frame or box (1), fastened on this shaft Eccentric disks (4), lifting rods (5) and levers (6) are carried out. uv »™ this training is suitable toat cutting out relatively k, a Merten very soft silage, for example from siiertJn Feed carts, never aocr to cut out of fibrous feed, such as grass, ru-sitter u. d, l. Also is with the known 4 a cutting out of compact, rectangular shape SiU-blÖL-ke not possible. Cutting out ς -w in G-shape of rectangular blocks also has the VnrHI that an undesirable fermentation of the selected nittcncn S. layer blocks and the prohibitive in the silo Feed is largely avoided. The invention is therefore based on the task to create a structure of the type mentioned at the beginning, that makes it possible. All types of silage in proportion Bulky, compact and quadenorrmger blocks can be removed from a silo in one operation.
