Abstract
A coupling device, particularly for power-operated machines for agricultural use or the like, includes an oscillating frame which is detachably connected to a hitch assembly of an engine and a movable connection for associating with the oscillating frame the working means of a power-operated machine. The oscillating frame and the movable connecting means are configured to maintain, during use, the working plane of the power-operated machine substantially parallel to the ground, independently of the plane of arrangement of the wheels or of the tracks of the engine.
Claims12
A coupling device for power-operated machines, comprising an oscillating frame which is detachably connectable to a hitch assembly of an engine of a motive machine and a movable connection means for associating working means of a power-operated machine to said oscillating frame;
- said oscillating frame and said movable connection means being configured to maintain a working plane of said power-operated machine substantially parallel to the ground, independently of the plane of arrangement of wheels or of tracks of said motive machine, during use;
- said oscillating frame comprising a first portion for suspension of said working means of said power-operated machine and a second portion for coupling to said hitch assembly;
- said first portion being rotatably connected to said second portion about a first oscillation axis that is substantially parallel to the advancement direction of said power-operated machine;
- said first portion comprising a contoured arm which protrudes from a first plate which is arranged transversely to said first oscillation axis;
- said second portion comprising a second plate, which is substantially parallel to said first plate and is provided with a means for interconnection to said hitch assembly;
- said first plate being connected rotatably to said second plate by means of a fulcrum which defines said first oscillation axis;
- said movable connection means comprising at least one ball-and-socket joint which is arranged at a free end of said contoured arm;
- said ball-and-socket joint defining a second oscillation axis which is transverse to said first oscillation axis.
