Abstract
The invention aims to provide a core bit good in coring effect. An internally-cooled drill comprises a shank and a cutting edge portion disposed at the end of the shank. The cutting edge portion is formed by splicing a plurality of segments; the cutting edge portion is provided with an inner tube which is hollow. The core bit is characterized in that the shank penetrates an inflow passage, and the inner wall of the inner tube is provided with a water outlet communicated with the inflow passage. Water can be pumped in from the inflow passage by a water pump during drilling, the water flows from the water outlet of the inner wall of the inner tube into the inner tube and forms a lubricating film on the inner wall of the inner tube, friction between the inner wall of the inner tube and core material is reduced, and accordingly, the core material can be kept intact and post-extraction subsequent research is facilitated.
Description
Technical field
The invention belongs to bit technique field, specially refer to a kind of effective coring bit of core of getting.
Background technology
Coring bit can, in boring, take out part material, for follow-up analysis and research.Traditional coring bit structure is as follows: its blade is spliced by several sections, and blade is provided with the inner core of hollow, and when boring, core material will pierce the inner core of blade like this.But, due to when boring inner core inwall and the core material of getting between frictional force larger, can make core material rupture, be unfavorable for follow-up get core and analysis and research.
Summary of the invention
The object of the invention is to propose a kind of effective coring bit of core of getting.
Interior cold brill of the present invention comprises drillstock and the blade that is arranged on drillstock end, and described blade is spliced by several sections, and blade is provided with the inner core of hollow; Key is that described drillstock runs through and is provided with into aquaporin, and the inwall of described inner core is provided with and the delivery port that enters aquaporin and communicate.
In boring, can utilize water pump that water is pressed into from entering aquaporin, water is drained in inner core from the delivery port of inner core inwall, water forms one deck lubricating film at the inwall of inner core, reduced the frictional force between inner core inwall and core material, thereby make core material keep complete, be convenient to take out and follow-up research.
Further, for improving lubricant effect, described delivery port has a plurality of, and equal partition is distributed in the inwall of inner core.
Coring bit of the present invention sets out the mouth of a river by the inwall at inner core, can reduce the frictional force between inner core inwall and core material, thereby makes core material keep complete, is convenient to take out and follow-up research.
Accompanying drawing explanation
Fig. 1 is the structural representation of coring bit of the present invention.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operating principle etc.
Embodiment 1:
As shown in Figure 1, the coring bit of the present embodiment comprises drillstock 1 and the blade 2 that is arranged on drillstock 1 end, and described blade 2 is spliced by two sections, and blade 2 is provided with the inner core 3 of hollow; Key is that described drillstock 1 runs through and is provided with into aquaporin-4, and the inwall of described inner core 3 is evenly provided with a plurality of delivery ports 5 with entering aquaporin and communicating.
In boring, can utilize water pump that water is pressed into from entering aquaporin-4, water is drained in inner core 3 from the delivery port 5 of inner core 3 inwalls, water forms one deck lubricating film at the inwall of inner core 3, reduced the frictional force between inner core 3 inwalls and core material, thereby make core material keep complete, be convenient to take out and follow-up research.
Claims (2)
1. a coring bit, comprises drillstock and the blade that is arranged on drillstock end, and described blade is spliced by several sections, and blade is provided with the inner core of hollow; It is characterized in that described drillstock runs through is provided with into aquaporin, and the inwall of described inner core is provided with and the delivery port that enters aquaporin and communicate.
2. coring bit according to claim 1, is characterized in that described delivery port has a plurality of, and equal partition is distributed in the inwall of inner core.
