Zusammenfassung: | The invention discloses an efficient bidirectional vibration impact power head in the technical field of geological drilling, which comprises a power joint, an upper bearing seat, two positioning rings, a lower bearing seat and a water injection sleeve which are sequentially connected to form a stable supporting sleeve, an output shaft, a transmission shaft and a driving shaft sequentially form a complete rotating shaft, and the rotating shaft is sleeved on the supporting sleeve to rotate. Two-way impact vibration is conducted on the power head by compressing the impact spring connected with the two vibroflotation rings, the two-way vibration impact function of downward drilling and upward lifting can be achieved, the medium-free impact rotary drilling function of shallow hole drilling can be achieved, and the drilling work efficiency is improved. The device is particularly suitable for drilling coring or sampling of a shallow pebble bed and drilling coring or sampling of a shallow sandy soil layer. The devic |
