IMPACT DEVICE WITH HYDRAULIC DRIVE Russian patent published in 2010 - IPC E02F3/40 E02F5/30 

FIELD: mining.

SUBSTANCE: group of inventions relates to the field of mining, in particular to impact devices including driving mechanism of impact action. Drive of impact action in assembly includes body, bottom and forms receiving cavity for location of drive. Hydraulic drive is fixed in receiving cavity, having head, at least one section of which protrudes forward relative to specified receiving cavity. Front part is fixed to front part of body at a certain distance from receiving cavity, and as a result space is formed between back part of front part and front end of head. Front part includes at least one longitudinal hollow guide for dowel pin, at the same time each of dowel pins has back and front end. Back end of dowel pin passes through specified space between front part and front wall for engagement of front end of head, which protrudes beyond front surface of body. Multiple hydraulic connectors are installed on body, being connected to drive with the possibility of control. After actuation of drive, drive head executes reciprocal motion, cyclically affecting impact action at dowel pin.

EFFECT: simplification of design.
