Abstract
The utility model relates to a well drilling and coring sampler which comprises a hollow coring bit, a drill rod and a coring and sampling device. The tail portion of the hollow coring bit is in threaded connection with the drill rod, and the coring and sampling device is arranged in a cavity, communicated with the drill rod, in the coring bit. The coring and sampling device comprises a coring pipe with one open end, a fixing pipe and a fishing spearhead, the open end of the coring pipe is arranged in the cavity of the coring bit, and the sealed end of the coring pipe is in threaded connection with the bottom end of the fixing pipe. The bottom of the fishing spearhead is vertically and evenly provided with four connecting rods, and the top end of the fixing pipe is arranged among the four connecting rods. The well drilling and coring sampler has the advantages that operation is simple, rod lifting and coring do not need to be conducted repeatedly, labor and material resources are reduced, and the coring rate is improved.
Description
Technical field:
The utility model relates to a kind of barrel of core-drilling tool for hydrogeologic prospecting, relates in particular to the drilling extracting core sampler that a kind of fast and easy is got core.
Background technology:
Drilling extracting core is to provide the important channel of underground firsthand information, be also obtain formation lithology, underground containing wet goods data the most intuitively, the most effective mode.Existing drilling extracting core device adopts drilling rod to connect the pattern of coring bit, after drilling extracting core, drilling rod need to be put forward to get core at every turn, has caused like this drilling extracting core complex operation, has reduced and got core efficiency.
Utility model content:
The purpose of this utility model is to overcome the deficiency that prior art exists and a kind of device of fast and easy drilling extracting core sampling is provided.
A drilling extracting core sampler, comprises coring bit, the drilling rod of hollow and gets core sampling apparatus, the afterbody of described coring bit is connected with described drill rod thread, described in get core sampling apparatus and be placed in the cavity that described coring bit is communicated with described drilling rod; Describedly get corer, the stationary pipes that core sampling apparatus comprises an end opening and drag for spearhead, the openend of described corer is placed in the cavity of described coring bit, and the openend of described corer is communicated with the openend of described coring bit; The blind end of described corer is threaded with the bottom of described stationary pipes; On the sidewall of the middle part of described stationary pipes, along described fixed tubular axle to having fixedly groove, in described fixedly groove, one end is provided with two by the fixing slide calliper rule of articulated manner, and pin joint be take as the center of circle in the outer end of described slide calliper rule, and outwards rotary expansion stretches out; In described fixedly groove, the other end is provided with the tensioning spring with the corresponding connection of described slide calliper rule, and described tensioning spring makes the outer end of described slide calliper rule remain flared state; On the sidewall of the top of described stationary pipes along described fixed tubular axle to having spacing groove; In the described vertical parallel of spearhead bottom even of dragging for, show four connecting rods, in described connecting rod bottom, be provided with annular and tighten up hoop; Described stationary pipes top is placed between four described connecting rods; Described annular tightens up hoop slip cap and is contained on the described stationary pipes outer wall of described fixedly groove below; The outer end of described slide calliper rule outwards launches from the gap between two adjacent described connecting rods to stretch out; Between the described connecting rod of correspondence, be fixed with the gag lever post through described spacing groove.
Compared with prior art, the beneficial effects of the utility model are: use simple to operately, need not get core by extracting back and forth drilling rod, saved human and material resources, improved and got core efficiency.

Coring bit 1, drilling rod 2, get core sampling apparatus 3, corer 4, stationary pipes 5, drag for spearhead 6, fixedly groove 7, slide calliper rule 8, tensioning spring 9, spacing groove 10, connecting rod 11, annular tighten up hoop 12, gag lever post 13.
The specific embodiment:
As depicted in figs. 1 and 2, a kind of drilling extracting core sampler, it comprises coring bit 1, the drilling rod 2 of hollow and gets core sampling apparatus 3, the afterbody of coring bit 1 is threaded with drilling rod 2, gets core sampling apparatus 3 and is placed in the cavity that coring bit 1 is communicated with drilling rod 2; As shown in Figures 3 to 8, get corer 4, the stationary pipes 5 that core sampling apparatus 3 comprises an end opening and drag for spearhead 6; The openend of corer 4 is placed in the cavity of coring bit 1, and the openend of corer 4 is communicated with the openend of coring bit 1; The blind end of corer 4 is threaded with the bottom of stationary pipes 5; On the sidewall of the middle part of stationary pipes 5, along stationary pipes 5, axially have fixedly groove 7, pin joint be take as the center of circle in the outer end of slide calliper rule 8 by the fixing slide calliper rule 8 of articulated manner in fixing interior one end of groove 7, to be provided with two, and outwards rotary expansion stretches out; At the fixing interior other end of groove 7, be provided with the tensioning spring 9 with slide calliper rule 8 corresponding connections, tensioning spring 9 makes the outer end of slide calliper rule 8 remain flared state; On the sidewall of the top of stationary pipes 5, along stationary pipes 5, axially have spacing groove 10; Show four connecting rods 11 dragging for the vertical parallel of spearhead 6 bottom even, in connecting rod 11 bottoms, be provided with annular and tighten up hoop 12; Stationary pipes 5 tops are placed between four connecting rods 11; Annular tightens up hoop 12 slip caps and is contained on stationary pipes 5 outer walls of fixing groove 7 belows; The outer end of slide calliper rule 8 outwards launches from the gap between two adjacent connecting rods 11 to stretch out; Between corresponding connecting rod 11, be fixed with the gag lever post 13 through spacing groove 10.
A kind of operating principle of drilling extracting core sampler: during coring bit 1 drilling extracting core, get the slide calliper rule 8 of core sampling apparatus 3 under the effect of tensioning spring 9, the inwall of drilling rod 2 is blocked in the outer end of slide calliper rule 8, gets core sampling apparatus 3 along with coring bit 1 and drilling rod 2 synchronous rotaries carry out drilling extracting core; After the corer 4 of getting core sampling apparatus 3 is got core, with traditional carry that core bar upwards gets core sampling apparatus 3 drag for spearhead 6, when dragging for spearhead 6 and being upwards extracted, annular tightens up hoop 12 along the axial upward sliding of stationary pipes 5, the outer end of slide calliper rule 8 is inwardly regained, the outer end of slide calliper rule 8 is separated with the inwall of drilling rod 2, get core sampling apparatus 3 along with carry core bar one drilling rod 2 interior on rise, core sampling apparatus 3 is got in taking-up, saved like this in traditional drilling extracting core process and extracted back and forth the step that drilling rod is got core, improved and got core efficiency.
