Interior drilling rod, 9 positioning rings, 10 inside grooves, 11 positioning tooths, 12 locating slots, 13 locating pieces, 14 coring slots, 15 clamping plates, 16 positioning are led
Slot, 17 abutment sleeves, 18 reset springs, 19 guiding skewbacks, 20 auxiliary drill bits.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the technical solution in the utility model, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution：A kind of water proof ground core bit, including upper company
Extension bar 4, the lower section of upper connecting rod 4, which is spirally connected, is equipped with lower connecting rod 3, and lower connecting rod 3 is internally provided with coring with upper connecting rod 4
Slot 14 is equipped with interior drilling rod 8 in coring slot 14 with one heart, and the end of interior drilling rod 8 is provided with main drill bit 1, is provided in interior drilling rod 8
Drainage pipeline 7, and upper connecting rod 4 is connect by being spirally connected pipe 6 with external auxiliary drilling rod, is led between interior drilling rod 8 and upper connecting rod 4
It is fixed to cross positioning column 5, and the lower end of lower connecting rod 3 is integrally formed with the positioning ring 9 for being socketed in interior 8 outside of drilling rod, in positioning ring 9
It has been placed equidistant with locating channel 16, and abutment sleeve 17, abutment sleeve 17 are equipped with by reset spring 18 in locating channel 16
Upper end integrally formed with clamping plate 15, and the front end of clamping plate 15 is integrally formed with guiding skewback 19.
Further, locating slot 12 is provided in upper connecting rod 4, and the outside of interior drilling rod 8 is provided with and locating slot 12
The locating piece 13 matched.
Further, the outside of positioning column 5 is provided with inside groove 10, and the inner wall of inside groove 10 has been placed equidistant with positioning tooth 11.
Further, the rear end of main drill bit 1 has been uniformly arranged at least three clamping blocks 2, and be provided on lower connecting rod 3 with
The matched main drill bit clamping slot of clamping block 2.
Working principle：When the device works, the rear end for the pipe 6 that is spirally connected can connect water pump, benefit during main drill bit 1 drills through
It is internally supplied water with water pump, prevents main drill bit 1 from overheating, water is then extracted to the mud for removing bore inner, facilitates continuation
It drills through.When main drill bit 1 gets specified location by drilling, which is lifted out and is drilled, then remove main drill bit 1, and by the dress
It sets and reinserts in drilling, continue the mud for extracting bore inner by water pump, while starting to ground using auxiliary drill bit 20
Coremaking, since auxiliary drill bit 20 is annular bit, the core at manufacture is that can work as system just into the cylindrical body of coring slot 14
After the completion of core, lower connecting rod 3 continue to rotate and stop it is mobile at this time using the circular cutter on clamping plate 15 to the root of core into
Core root is gradually cut off under the extruding of reset spring 18 and is finally cut off by row ring cutting, circular cutter, the rock after cutting off at this time
Core is closed completely into coring slot 14, and since positioning ring 9 at this time is clamped plate 15, and core will not drop out, at this time
The device is proposed to take out what the core being located in coring slot 14 was completed after drilling and unscrewing lower connecting rod 3.Using this
Device can not only avoid the problem for excessively causing drilling difficult due to mud in location of the coring procedure, and can easily cut off rock
Core and falling for core can be effectively avoided during extracting core, there is very high practical value.
