Specific embodiment
Below in conjunction with Figure of description, the technical scheme in the embodiment of the utility model is clearly and completely retouched
It states, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on this
Embodiment in utility model, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, fall within the protection scope of the utility model.
As shown in Figure 1, 2, 3, a kind of air down-hole hammer local reverse-circulation equipment, including superstructure and underground knot
Structure, it is characterised in that: the superstructure includes drilling cramp 1, power head 2,10 sum aggregate slag bath 15 of air compressor machine, the underground structure packet
Pressure maintaining ring 4, flow guiding connector 5, cover cylinder 7, down-hole hammer 8 and drill bit 9 are included, the underground structure is connect by drilling rod 3 with superstructure；
The drilling rod 3 includes a residue outlet 31 and several air inlet tubules 32, and the upper port of the residue outlet 31 passes through scum pipe 14
It is connected to collection slag bath 15, the air inlet tubule 32 is connected to by air hose 12 with air compressor machine 10；The top of the drilling rod 3 and dynamic
Power head 2 is fixedly connected, and bottom end is successively arranged pressure maintaining ring 4, flow guiding connector 5, damper 6, down-hole hammer 8 and drill bit 9 from top to bottom；Institute
The outside that flow guiding connector 5, damper 6 and down-hole hammer 8 is arranged in cover cylinder 7 is stated, top is fixedly connected with the bottom surface of pressure maintaining ring 4；
The hole wall bottom hole of the cover cylinder 7, pressure maintaining ring 4 and drilled as holes forms seal-off pressure cabin.
The seal-off pressure cabin that the utility model is formed by the hole wall bottom hole of pressure maintaining ring 4, cover cylinder 7 and drilled as holes, makes pressure
Cabin keeps smaller and fixed volume, and also very little can make gas under lesser air air output to the cross-sectional area of residue outlet 31
