An inner pipe is connected in the outer pipe through an inner pipe connector. A ball valve seat is arranged at one end of the inner pipe connector and provided with a steel ball. A connecting sleeve is arranged at the other end of the inner pipe connector. A nut is arranged in the inner pipe connector and the connecting sleeve. One end of the nut is provided with a single direction thrust ball bearing and a single-row radial ball bearing. An adjusting nut is arranged at one end of the single-row radial ball bearing and connected with an adjusting rod. The adjusting rod is connected with a connector. The connector is connected with the outer pipe through alloy and is provided with a coring opening. The coring device has the advantages of being convenient and fast to use and high in coring efficiency and meanwhile can achieve circulation, cooling and lubrication effects.

Description

Corer
Technical field
The present invention is specifically related to a kind of corer, belongs to drilling technology field.
Background technology
Corer is the instrument of a kind of indispensability in engineering drilling technology, and when engineering driller punches on hard material, the brill core that drilled material is formed in drill bit can not Automatic-falling, needs to take out from hole boring core by other instruments.At present, one is that punch operation person normally will bore core and drilled material disconnects, and brill core is tied up by recycling steel wire, then pulls out from its hole; In addition, be adopt corer, old-fashioned single hole corer gets core while creeping into, and easily makes got thing edge burn rotten on the one hand, and single hole is not easy to extract on the other hand, and extraction efficiency is low.Therefore, need to provide a kind of new technical scheme to solve.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of corer, this corer is convenient to use, and extraction efficiency is high, can also play circulation cooling lubrication effect simultaneously.
Technical problem to be solved by this invention realizes by the following technical solutions:
Corer, it comprises outer pipe bit and interior pipe bit, described outer pipe bit and interior pipe bit are movably connected by box cupling, outer tube is provided with in described interior pipe bit, interior pipe is connected with by inner pipe joint in described outer tube, described one end being positioned at inner pipe joint is provided with ball valve seat, described ball valve seat is provided with steel ball, the other end of described inner pipe joint is provided with adapter sleeve, describedly be positioned at inner pipe joint and adapter sleeve is provided with nut, the described nut one end that is positioned at is provided with single direction thrust ball bearing and single-row radial ball bearing, the described single-row radial ball bearing one end that is positioned at is provided with adjusting nut, described adjusting nut is connected with adjusting rod, described adjusting rod is connected with joint, described joint is connected with outer tube by alloy, and described joint is also provided with and gets core mouth.
As optimal technical scheme, described in be positioned at outer tube and be also provided with clip spring seat, described clip spring seat is provided with jump ring, and described jump ring is provided with back-up ring.
As optimal technical scheme, describedly between interior pipe bit and outer tube, be provided with back-up ring.
As optimal technical scheme, described nut is also provided with nut sleeve, describedly between nut and single direction thrust ball bearing, is provided with pad, describedly between single direction thrust ball bearing and single-row radial ball bearing, be provided with packing ring.
As optimal technical scheme, described ball valve seat is provided with pore, described steel ball is movably arranged on pore.
The invention has the beneficial effects as follows:
1) easy to use, simple to operate, automaticity is high, and safety factor is high, and running cost is low;
2) work of creeping into is responsible for by outer pipe bit, and coal core is entered in corer by interior pipe bit.When extracting, by the Action of Gravity Field of steel ball, ball valve seat pore is blocked by steel ball, thus make interior pipe form confined space, and then can smoothly coal core be taken out, greatly strengthen extraction efficiency; Mud plays the effect of cooling and lubricating by the space circulation between inner and outer pipes simultaneously, protects corer, extends application life.
