Impactor includes cylinder body, piston, reversal valve, accumulator, drill steel seat, drill steel set, drill steel, rear cover, it further includes being arranged hydraulic
Rubber air spring between impactor tail portion and shell, rubber air spring include lower end-plate, connection flange, air bag, on
End-plate, charge valve and screw.In order to avoid the rigid contact of hydraulic impactor and case weld part, worker is made to hold shell
On upper, middle and lower handle work when, not by hydraulic impactor vibration influenced, although the device be provided with earthquake isolating equipment,
In actual use, cushioning effect effect is not fine, still can be strongly by hydraulic when worker holds lower handle work
The influence of impactor vibration, therefore need to improve it.
