Abstract
A kind of the problem of cutter coring bit, effective solution underground hydrological observation wells mistake dislocation segment；Including ring block, ring block lower end is equipped with conical baffled, and ring block upper end is equipped with fixed ring, and there are six the first cutter type drill bits around even circumferential installation for the lower end of fixed ring, the interior survey of ring block is uniformly installed there are three fixed plate, and the second cutter type drill bit is housed in fixed plate；The utility model structure novel, rationally, such coring bit can be in various hard, tight formations, gravel layer and underwater operation carries out higher rate of penetration and works, and can increase substantially working efficiency for design, prolongs the service life.
Description
Technical field
The utility model relates to geological prospecting equipment technical field, in particular to a kind of cutter coring bit.
Background technique
The hydrology long view hole in underground is to be directly arranged in underground, is vertically constructed from underworkings to deep aquifers, long-term observation
The drilling of water-bearing layer water level.Multiple water-bearing layers can be observed excessively, can establish underground Hydrological observation system, there is cost
Low, easy the advantages of protecting, can be used as auxiliary water source and coal column can not be retained or stay coal column less, but limited by conditions down-hole,
If because underground hydrological observation wells occur dislocation section, cause to flood well or flood the accident taken, borehole observation station may also by
It floods, so needing to handle mine water text peephole dislocation bad break problem using drilling extracting core equipment.
Existing drilling extracting core drill bit includes making cutting edge with hard alloy blocks and being answered with diamond and dimond synneusis grain
Close the various drill bits that piece is cutting element.These drill bits encounter firm hard formation, fine and close medium ground and in, thick, macrosome gravel contains
Rate of penetration will drop to 0.5 m/h hereinafter, making efficient middle long cylinder drilling extracting core work when amount accounts for 40% or more stratum
Skill technology can not be applied.Especially in brill chance, when thick, macrosome gravel accounts for 40% or more gravel layer, single footage per bit meeting
5m is dropped to hereinafter, steeply rising the unit cost of drilling extracting core.
So needing a kind of cutter coring bit to solve the problems, such as this, in particular circumstances using gear wheel coring.
Utility model content
For above situation, for the defect for overcoming the prior art, the purpose of the utility model is just to provide a kind of cutter
The problem of coring bit, effective solution underground hydrological observation wells mistake dislocation segment and drilling tool and casing annular are crept into.
Its technical solution solved is that the utility model includes ring block, and ring block lower end is equipped with conical baffled, ring block
Upper end is equipped with fixed ring, and around even circumferential installation, there are six the first cutter type drill bit, the interior surveys of ring block for the lower end of fixed ring
Uniformly installation is equipped with the second cutter type drill bit there are three fixed plate in fixed plate.
The beneficial effects of the utility model are: the utility model structure novel, rationally, such coring bit can be for design
In various hard, tight formations, gravel layer and underwater operation carries out higher rate of penetration and works, and can significantly mention
High working efficiency, prolongs the service life, in particular circumstances using gear wheel coring.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the top view of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
Embodiment:
It is provided by Fig. 1 to Fig. 2, the utility model includes ring block 1, and 1 lower end of ring block is equipped with conical baffled 2, taper gear
The internal diameter of the upper end of plate 2 is less than the internal diameter of lower end, and 1 upper end of ring block is equipped with fixed ring 3, can be fixedly mounted by fixed ring 3
In coring tube lower end, around even circumferential installation, there are six the first cutter type drill bit 4, the interior surveys of ring block 1 for the lower end of fixed ring 3
Uniformly installation is equipped with the second cutter type drill bit 6, passes through the first cutter type drill bit of six, outside there are three fixed plate 5 in fixed plate 5
4 and three the second cutter type drill bits 6 of inside rock can be crushed, and cooperate with coring tube and take the core in drill bit
Out.
It is tiltedly directed toward in fixed ring 3 in the direction of the gear wheel of first cutter type drill bit 4 and the second cutter type drill bit 6
Mandrel.
The fixed plate 5 is fixedly connected by bolt with ring block 1, the connector peace of second cutter type drill bit 6
In fixed plate 5, when the damage of the second cutter type drill bit 6, the second cutter type drill bit 6 can be carried out by control bolt
Replacement, extends the service life of device.
In order to enable the first cutter type drill bit 4 can be with 6 cooperating of the second cutter type drill bit, first cutter
The connector of drill bit 4 is fixedly mounted on 3 lower end of fixed ring, and the connector lower end of the first cutter type drill bit 4 passes through conical baffled 2, energy
It is enough to make fragmented rock portion in the device always when being crushed to rock, it is convenient for coring.
The tooth of first cutter type drill bit 4 and the second cutter type drill bit 6 is all made of chisel insert, suitable for broken
The broken soft formation and medium ground for having high speed.
First cutter type drill bit 4 and the second cutter type drill bit 6 is all made of shape metallic leak-proof structure.
3 upper end of fixed ring is equipped with multiple threaded holes 7, can be by the cooperation of bolt and threaded hole 7, so that can root
Device is dismounted according to actual conditions.
When the utility model is used, fixed ring 3 is fixedly mounted on by coring tube lower end by bolt, it can be to mine water
The long view hole of text carries out broken coring, repairs to the dislocation section of the long view hole of the underground hydrology.
The beneficial effects of the utility model are: the utility model structure novel, rationally, such coring bit can be for design
In various hard, tight formations, gravel layer and underwater operation carries out higher rate of penetration and works, and can significantly mention
High working efficiency, prolongs the service life, in particular circumstances using gear wheel coring.
