RIPPER WITH SPRING-ACTUATED BIDIRECTIONAL ENERGY STORAGE DEVICE Russian patent published in 2012 - IPC E02F5/32 

FIELD: machine building.

SUBSTANCE: ripper contains a hinged frame and a loosening rack pivotally mounted on a hinged frame and connected to the frame through a spring-loaded energy storage device. At that the spring-loaded energy storage device comprises the body and is equipped with a central disk connected via a rod to a ripper stem. The central disk is adjoined on both sides with additional disks with the rods telescopically mounted in the central part, connected in pairs with the brackets mounted on the free ends of the rods along the diameter line, with the adjusting device in the form of hydraulic cylinders which are placed between brackets. The central disk on both sides and the additional disks on the side of the rods are equipped with the concentrically arranged coil springs, the free ends of which are connected to the internal sides of the ends of the body. The ripper is also equipped with the disk of initial spring load and the rear end of the internal side of the accumulator body and connected by means of the swing link to the disk motion control hydro cylinders installed on the body.

EFFECT: increased efficiency of soil ripping due to reduced traction and dynamic loads acting on the base machine, and their transfer to the zone of destruction of soil in a wide range of the frequency of forced oscillations.
