Abstract
The utility model discloses a coring tool with circular grooves on a knife back, which mainly comprises a metal chip removal drill bit, as well as a drill stem and a coring drill which are respectively connected with two ends of the metal chip removal drill bit. The metal chip removal drill bit, the drill stem and the coring drill are dismountable so as to prevent the overall coring tool from scrapping. A plurality of grooves are arranged on the outer surface of a convex knife blade outside the metal chip removal drill bit so as to enhance abrasive resistance and stability.
Description
Technical field
The utility model relates to the coring tool that uses in the drilling project, and wherein the utility model relates generally to the coring tool that the knife back is opened circular groove.
Background technology
Drill bit is to go out through hole or blind hole in order to drilling on solid material, and can be to the cutter of existing hole reaming.Drill bit commonly used mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Though reamer and counterbit can not be holed, also they are included into one type on drill bit traditionally on solid material.
In drilling process, coring tool is to take the used drilling tool of rock core when creeping into.In order to improve core recovery percentage and quality; Different according to creeping into rock ore bed integrated degree; Adopt dissimilar and the utensil of coring structure respectively, like single tube, two-tube, three layers of pipe coring tool, coring with local inverse circulation instrument, sometimes also will be with the special-purpose coring tool of taking non-disturbed sample.
Existing coring tool, though be single tube, two-tube, or three layers are managed, and all adopt; Core bit, chip removal drill bit, drilling rod all-in-one-piece structure; This design, in probing was used, any position in core bit, chip removal drill bit, drilling rod existed under the damaged condition; Whole coring tool is directly scrapped, thereby causes the interruption of the work of drilling.
In addition, existing coring tool, for the geological conditions of hard formation, it is relatively poor respectively in abrasion resistance and stability, therefore also need strengthen for abrasion resistance and stability, could satisfy the hard formation probing.
The utility model content
The purpose of the utility model be to provide a kind of detachable, intensity is high, abrasion resistance is good, good stability, easy and simple to handle, coring tool that the knife back that aid is complete is opened circular groove.
The utility model implementation is following: the knife back is driven the coring tool of circular groove, mainly by metal chip removal drill bit, and the drilling rod and the column drill formation that are connected to metal chip removal drill bit two ends.
Said metal chip removal drill bit is a hollow cylindrical, and its external surface has the spill chip area, is provided with protruding blade between the adjacent two spill chip areas.
Said protruding blade external surface is provided with some grooves, is provided with in the said groove with groove is complementary to agree with piece.
The transverse cross-sectional shape of said groove is circular.
The said piece that agrees with is provided with some boss.
Described boss number is between 10 to 50.
Said transverse cross-sectional shape of agreeing with piece is a gear shape.
The diameter of said groove is between 2 centimetres to 0.5 centimetre.
Be connected through the silk thread mouth that is provided with between metal chip removal drill bit and drilling rod and the column drill; Make to split metal chip removal drill bit, drilling rod, column drill, when metal chip removal drill bit, drilling rod, column drill; Damaging appears in any position; When needing to change, we can split the position of needs get off, again replacement again.Like this, be unlikely to occur when damaging appears in any position, whole coring tool will face the situation of scrapping.
The protruding blade external surface of metal chip removal drill bit is provided with some grooves, and the said piece that agrees with uses welding procedure to be embedded in the groove.It agrees with the piece transverse cross-sectional shape and is set to gear shape, has guaranteed in drilling process, has increased the abrasion resistance and the stability of metal chip removal drill bit.
The utility model compared with prior art has the following advantages and beneficial effect: metal chip removal drill bit, drilling rod, column drill are detachable; Avoid whole coring tool to scrap; The outer protruding blade external surface of its metal chip removal drill bit is provided with some grooves, increases abrasion resistance and closes stability.
Description of drawings
Fig. 1 is the syndeton sketch map of the utility model.
Fig. 2 is for the utility model groove and agree with the block structure sketch map.
Label among the figure is expressed as respectively: 1, drilling rod; 2, metal chip removal drill bit; 3, column drill; 21, protruding blade; 211, groove; 212, agree with piece; 22, spill chip area.
The specific embodiment
As shown in Figure 1, the knife back is driven the coring tool of circular groove, mainly by metal chip removal drill bit 2, and the drilling rod 1 and column drill 3 formations that are connected to metal chip removal drill bit 2 two ends.
Metal chip removal drill bit 2 is a hollow cylindrical, and its external surface has spill chip area 22, is provided with protruding blade 21 between the adjacent two spill chip areas 22.
Protruding blade 21 external surfaces are provided with some grooves 211, are provided with in the said groove 211 with groove 211 is complementary to agree with piece 212.
As shown in Figure 2, the transverse cross-sectional shape of groove 211 is circular.
Agree with piece 212 and be provided with some boss 2121.
Boss 2121 numbers are 10.
The transverse cross-sectional shape of agreeing with piece 212 is a gear shape.
The diameter of groove 211 is 1 centimetre.
During use, drilling rod 1 is connected with metal chip removal drill bit 2, simultaneously metal chip removal drill bit 2 is connected with column drill 3, utilize metal chip removal drill bit 2 to stablize and increase anti-wear performance.
The utility model is topmost to be characterised in that, is provided with some grooves 211 at protruding blade 21 external surfaces of metal chip removal drill bit 2, adopt simultaneously the cross section be gear shape agree with piece 212, be embedded in the groove 211.Increase abrasion resistance with this, prevent that metal chip removal drill bit 2 from running into hard geology, damage coring tool.
As stated, then can well realize the utility model.
