The invention relates to the construction and mining and can be used when developing a robust and frozen ground.

Known Ripper for developing durable and frozen soils, including basic machine, hinged frame with the control mechanism and loosening the rack, which is pivotally mounted on a hinged frame and connected with the latter through an adjustable spring system containing a set of concentric spaced springs (see A.S. No. 594260, IPC 02F 5/30, EPUB).

This Ripper is provided by regulation of the total height of the spring system, but the speed increases rigidity, and the law on which there is a growth stiffness remains the same (the distance between free ends of the springs relative to each other is not regulated).

However, the cutting force on the working body is dependent on the physico-mechanical properties of the developed soil, design of work equipment, modes of motion of the machine base and the other, i.e. the frequency and amplitude of changes in cutting forces can take on different meanings in a wide range of their changes. Therefore, to obtain in loosening the equipment to the desired frequency and amplitude of oscillation of the working body, corresponding to the change of external influences, it is necessary to change the characteristics of rigidity and preliminary tucked up panel is Gogo element within wide limits.

Closest to the claimed Ripper is to develop frozen and solid soils containing basic machine, parallelogram suspension frame, on which the hinge is mounted Ripper tooth, and elastic system containing fixed on the frame of the master cylinder with the piston on the rod, a power shaft, passed through the end wall of the cylinder and connected through a hinge rod from loosening tooth, (see patent No. 1176944, IPC 02F 5/30, published. 07.09.85).

This Ripper, with the aim of improving its service, the main cylinder of the elastic system (battery power) is located outside its auxiliary piston chamber which is communicated with the working cavity using is made in the case of a channel with a controlled valve, and the case of the additional cylinder is connected with the rod of his control cylinders, mounted concentric with the casing of the main cylinder and can move inside made in the rod and the piston of the last cavity, with the power rod is omitted in the cavity of the additional cylinder, which with the help of made in the case of the last hole communicated with the working cavity of the main cylinder.

This elastic system with adjustable parameters is the energy storage unilateral action. When the movement of the rack in the opposite direction, the force of the sun is animalsa elastic element, with constant stiffness. Therefore, in the case of movement Ripper hours on battery power, it's even possible to disengage the rack from the elastic system, which leads to disruption of harmonic or nearly harmonic oscillations of the working body and disturbs the steady driving mode of the base of the machine, thereby increasing the vibration of the machine base, fatigue of the operator, etc. Currently characterized by loss of part of the kinetic energy stored up in the bar, which is dissipated within the system "Ripper hour - elements of the hinge - base machine. The energy input to the destruction of the soil will decrease (see, for example, the book of A.A. Kharkevich Self-oscillations.- M: State publishing house of technical and theoretical literature, 1953.- 170 C, the book of Teodorczyk CYP self-oscillating systems.- M: Gostekhizdat, 1952. - 272, book Lozanskogo L.G. Course of theoretical mechanics. T 2. Dynamics / L.G. loitsyansky, A.I. Lurie. - M.: Nauka, 1983. - 640 (C).

The technical result of the invention is to increase the efficiency of loosening of the soil by reducing the dynamic loads acting on the base machine and the operator, and transmit them to the zone of destruction of soil in a wide range of changes in external loads, enabling remote control of the battery energy.

Housing of pneumatic accumulator is made in form of hollow cylinder with lower and upper flanged parts provided with concentric holes for coaxial fastening of upper flanged part of pneumatic accumulator to flanged part of hollow shank, for coaxial fastening of lower flanged part of pneumatic accumulator to flanged part of hollow rod housing made at a distance from its upper end face equal to height of housing of pneumatic accumulator. Seat installed on upper end face of hollow rod housing for limiting upwards movement of forced gas displacement piston. Spring for limiting downward movement of forced gas displacement piston is installed on upper end face of seat to limit upward movement exhaust control valve. Outer supply pipe is installed in central hole of forced gas displacement piston.

EFFECT: increased efficiency.
