Preferably, when observing to the direction of visual lines of drill hammer from casing, described first cutter ring, the 3rd cutter ring rotation side
To for counterclockwise, the rotation direction of described second cutter ring is clockwise.
Preferably, be provided with between the inner side end of described transmission component and the first cutter ring, the second cutter ring, the 3rd cutter ring close
Envelope elastic tape.
It is preferably located between dynamic transfering rod and transmission component and is provided with oil chamber.
Preferably, described dynamic transfering rod is provided with the slide block being slidably matched with body inwall.
Preferably, described first cutter ring and the second cutter ring are linked by one group of planetary gear group, described second cutter ring with
3rd cutter ring is linked by another group planetary gear group.
This utility model is compared to prior art, and it has the beneficial effects that: around drill hammer described in the utility model
Having the first cutter ring, the second cutter ring, the 3rd cutter ring, described first cutter ring, the second cutter ring, the 3rd cutter ring are used for shearing earth and inciting somebody to action
Earth detritus is dialled from pile foundation hole, enhances the destructive power of soil big to viscosity during operation, alleviates soil detritus to drill bit band
The burden come.This utility model simple in construction, enforcement conveniently, have wide sector application prospect.
