FIELD: mining and construction machines.
SUBSTANCE: invention relates to mining and construction machines and can be used in the development of solid or frozen soils, for the destruction of fractured rocks, hard road surfaces and for crushing oversized items. The working equipment of percussion action contains an arrow, to which a damping device with a percussion working body inside is hingedly and hydraulically attached. The damping device is made in the form of a cylindrical cage with a set of rubber-metal disks, covering the impact working body and compressed by clamps. Clamps compress the disc under the action of a hydraulic cylinder connected to a hydraulic accumulator. Damping properties are regulated, in accordance with the type and condition of the material being developed, by changing the pressure of the hydraulic accumulator charging, regulated by a reducing hydraulic valve.
EFFECT: improving reliability and expanding operational capabilities.
