While cup is hung with the cooperation suspension of seat ring 21, bullet clamp 13 open and coordinate clamping with bullet card room 15；Clamp 13 are played to paste
On the inwall of bullet card room 15, at this moment playing the upper end of clamp 13 has adapter coupling, can prevent the upward play of inner tube 44, there is bullet card room outward
15, bullet clamp 13 can be limited and further opened, in drilling by the shift fork in adapter coupling, band is moved clamp 13, make in
The assembly part of pipe 44 is rotated with drilling rod, in case relative motion causes to play the abrasion of clamp 13；The sliding sleeve 32 of the lower end of bearing 51,
Spring housing and the single action of inner tube 44, do not rotate with drilling rod, the bottom of outer tube 43 is additionally provided with centering ring 46 and coordinates with inner tube 44, prevents interior
Pipe 44 is rocked, and improves the single action stability of inner tube 44；
After suspension cup 20 coordinates suspension with seat ring 21, the path of flushing liquor is hindered, and forces flushing liquor to change flow direction, and overcome
Valve spring causes the operation downwards of valve stifled 24 so that washing liquid channel is opened, and simultaneously, the pressure on base pressure table can be bright
Aobvious to rise, pump pressure change turns to 5-10 atmospheric pressure.At this moment represent that the assembly of inner tube 44 has arrived at drilling position, can start to sweep sky
Drilling；The mechanism that notifies in place includes valve body 55, valve stifled 24, valve body spring 57 and passage of irrigation fluid 58.
When drilling rod is to certain position, rock core is full of inner tube 44, and rock core upper end applies upward thrust to inner tube 44, interior
Pipe 44 drives sliding sleeve 32 to run up, and sliding sleeve 32 drives cone washer 30 to run up, the extruding alarm cushion rubber 29 of cone washer 30
And be allowed to deform, pressure alarm cushion rubber 29 is in close contact the water flowing hole plug below valve after deforming with outer tube 43, causes pump pressure
Raise, play blocking alarm function, burning of bits accident can be prevented again, can now use fisher, salvage core；
Fisher with drag for spearhead 2 coordinate clamping after, run up, when core hardness is bigger, the bottom clip spring seat of inner tube 44
Jump ring 48 on 49 shrinks under the constraint of baffle ring 47, and core is held tightly and pulled off；The assembly of inner tube 44 is carried by rope
Ground is risen to, because the assembly length of inner tube 44 is more long, weight is larger, it is to avoid drag between spearhead 2 and recovery tube 10 that socket part is received repeatedly
Power is damaged greatly very much, will drag for and is set to be hinged between spearhead 2 and recovery tube 10.
The external diameter of Optimal Selection of Diamond Bits 50 is 114mm, and internal diameter is 80mm；The external diameter of outer tube 43 is 112mm, and internal diameter is
98mm；The external diameter of inner tube 44 is 89mm, and internal diameter is 83mm；Drilling rod external diameter is 110mm, and internal diameter is 98 mm；Joint external diameter is 112mm,
Internal diameter is 98mm, and connection screw thread is 1:22 taper threads, the depth of thread is 1mm, and definition components above is S144.S144 is a kind of Jie
In S95（HWL）With S120（PWL）Between drilling tool, it is too small that this drilling tool can either make up S95 drilling tool bores, can make up again
The excessive defect of power needed for PQ drilling tools, is the exploitation provides convenient of well drilling and coal bed gas.
As a result of brand-new processing technology, the torsional strength of drill rod thread is up to 32000N/M, and drilling depth is reachable
1500 meters, core recovery percentage 96%, simultaneously because the drilling rod internal diameter of S144 is φ 98, when appropriate depth is got into, can be used as S95
（Or HQ）Sleeve pipe effect, make S95（HQ）Drilling depth greatly improve.Due to the assembly of inner tube 44 and HQ inner tubes of S114 drilling tools
The structure of 44 assemblies has a common segment, therefore has the assembly part of part inner tube 44 can be exchanged with HQ.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of the technology of the present invention principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
Also should be regarded as the protection domain of invention.
