Abstract
Silage cutter has a U-shaped frame which is movable vertically on a mounting rack. The frame has a pair of lateral members and a front member connected thereto by a pair of corner coupling elements. Each member has a front and a rear cutting blade slidably mounted thereon and driven in opposite directions by an arrangement of a drive cylinder and a lever on each lateral member. The blades on the lateral members drive the blades or the front member through force transmitting means such as upper and lower sets of steel rollers in each corner coupling element.
Claims9
Silage cutting machine comprising
- a U-shaped holding frame having a pair of rigid lateral members and a front member extending therebetween, each lateral member having a forked end having a stationary pivot pin therein;
- a pair of corner coupling elements connecting said lateral members to said front member, said coupling elements having compressive force transmitting means therein;
- a pair of cutting blades mounted on each lateral member and on said front member, each pair comprising a front blade slidably mounted on one side of the member to which it is mounted and a rear blade slidably mounted on the other side of the member to which it is mounted, each blade having an end arm received in one of said coupling elements, each front blade transmitting force to another front blade by said force transmitting means, each rear blade transmitting force to another rear blade by said force transmitting means;
- and
- blade driving means mounted at the forked end of each lateral member, each said blade driving means comprising a drive lever pivoted on a respective said stationary pivot pin, each lever being connected to both the front and rear blades on the lateral member on which said lever is pivoted so that each front blade reciprocates oppositely to the rear blade of the same pair.
Silage cutting machine in accordance with claim 4, characterized in that the studs each have at their end a head protruding beyond the guide slot for the precise lateral guidance of the cutting blades.
