Detailed description of the invention
Below in conjunction with accompanying drawing and concrete enforcement, concrete introduction is done to the present invention.
With reference to Fig. 1 jetting equipment of the present invention, comprise: high-pressure hydraulic pump (3) and inversion are connected to the decompression tank (4) of water pump (3) delivery port and the hose (5) of convenient movement, connect the bent sub (6) of hose (5) and drilling well water pipe (2), drill bit (1).Wherein, high-pressure hydraulic pump (3) provides High-Pressure Water, and decompression tank (4) is inversion state, and the inside has air.Decompression tank (4) water storage when drill bit (1) bounces back, reduces hydraulic pressure during drill bit (1) retraction.
As previously mentioned, bent sub (6) has in the middle of sealing nut (28) and have sealing ring (27), seal up the gap between steel wire (33) and bent sub (6).
As previously mentioned, drilling well water pipe (2) front end is connected to drill sleeve (29), and there is snap ring (22) drill sleeve (29) front end, for blocking drill bit (1), stops drill bit (1) to depart from drill sleeve (29).
As previously mentioned, jetting equipment, high-pressure hydraulic pump (3) increases hydraulic pressure to drill bit (1), current are by delivery port (18), and to thimble (11) pressurization, thimble (11) extrudes forward, chisel edge (12) expanded diameter is slightly larger than drill sleeve (29), along with hydraulic pressure continues to increase, when hydraulic pressure is greater than the suction of magnet (16) magnet (17), drill bit (1) impacts forward.Current, through delivery port (18), spray from weep hole (19).By drill bit (1) impact produce landwaste or silt push open, landwaste or silt along drilling well water pipe (2) outer wall with current backspace well head.
As previously mentioned, because weep hole (19) is helical form, due to the thrust of current, also in rotation while drill bit (1) impacts forward.Bearing A(23) and bearing B(24), reduce drill bit (1) rotational resistance, hydraulic pressure is after weep hole (19) release, and hydraulic pressure reduces, due to, the impacting rebound power of cutter head (13), the elastic force of spring B (30), magnet (16), the suction of magnet (17), drill bit (1) bounces back, and reduce pressure tank (4) simultaneously, absorbs the hydraulic pressure that high-pressure hydraulic pump (2) increases., magnet (16), magnet (17) adsorbs, and seal current through rubber sheet gasket (25), wait hydraulic pressure again to exceed magnet (16), the suction of magnet (17), drill bit (1) carries out impact next time again, repeatedly carries out.
As previously mentioned, drilling well completes or needs repair and replacement drill bit (1), then turn off water pump (2) hydraulic pressure reduce, due to spring A(14) elastic force, thimble (11) bounce back, chisel edge (12) closes up, and drill bit (1) is proposed by steel wire (33).
As previously mentioned, drilling process, drilling well water pipe (2) constantly prolongation creeps into drill bit (1).
As previously mentioned, according to the performance of drill bit (1), select the high-pressure hydraulic pump (3) of desired flow.
As previously mentioned, jetting equipment, the power impacted as bit with High-Pressure Water.
As previously mentioned, basis is bright not only can bore peupendicular hole, can also horizontal well drilling.
The foregoing is only preferred embodiment example of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
