FIELD: soil or rock drilling.
SUBSTANCE: invention relates to rock drilling equipment. Hydraulically powered percussion mechanism comprises a piston mounted for reciprocating movement in the percussion mechanism to provide an impact on the drill bit, a pressurised fluid channel for delivering pressurised fluid to the percussion mechanism from the base machine to perform reciprocating movement of the piston; and a first accumulation unit for hydraulic fluid. First accumulation unit comprises a plurality of first accumulation elements. Each of the first accumulation elements is located in the same proximity to the piston, and the plurality of first accumulation elements fluidly communicate with the pressurised fluid channel of the percussion mechanism during the entire piston cycle.
EFFECT: technical result consists in ensuring the reliability and response time of the system in the equipment, as well as compactness of the equipment.
