Abstract
A rotary impacting apparatus comprises a housing, a rotor rotated in the housing, an impact member eccentrically held by the rotor, and a main reciprocative implement held reciprocatively at a forward end portion of the housing. The rotor rotates to hit the impact member for driving the main reciprocative implement into the ground for instance. The apparatus further includes an auxiliary oscillating mechanism for transmitting an impacting force from the impact member to pull the main reciprocative implement when the housing is pulled relative to the main reciprocative implement by a predetermined distance.
Claims8
A rotary impacting apparatus comprising:
- a housing;
- a rotor rotated in the housing by a driving source;
- an impact member eccentrically held by the rotor;
- and a main reciprocative implement held reciprocatively at a forward end portion of the housing;
- the impact member exerting an impacting force for pressing the main reciprocative implement when the housing is advanced relative to the main reciprocative implement;
- wherein the rotary impacting apparatus further includes an auxiliary oscillating mechanism for transmitting an impacting force from the impact member to pull the main reciprocative implement when the housing is pulled relative to the main reciprocative implement by a predetermined distance.
