Description
Technical field
The utility model relates to a kind of drill bit, especially relates to the external convex rope total cost management drill bit of a kind of steel used for geological prospecting.
Background technology
It is that one does not promote drilling rod that wire line coring creeps into, and by being fished for the drilling method of rock core in drilling rod by steel wire cable.Existing wire line coring drill bit can not realize total cost management, wire line coring to be crept into be transformed to total cost management time, need promote drilling rod by wire line coring bit change-over is comprehensive drill bit, just can realize total cost management.And in drilling process, during the comprehensive drill bit that need more renew, still will by after lifting drilling rod, just replaceable new comprehensive drill bit, probing is long for non-cutting time, and drilling efficiency is low, and labour intensity is large.
Utility model content
The technical problems to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, provides the steel that a kind of drilling efficiency is high external convex rope total cost management drill bit.
The utility model solves the technical scheme that its technical problem adopts:
The external convex rope total cost management drill bit of a kind of steel used for geological prospecting, comprise steel body, carcass is provided with above steel body, be hollow-core construction to steel body middle and upper part bottom described steel body, the outer face of carcass is bit bottom lip surface, bit bottom lip surface has limbers, and the bearing of trend of limbers is parallel with direction, drill bit axis; Bit bottom lip surface also has tank, described tank extends to steel external surface from the center of bit bottom lip surface along bit bottom lip surface, the initiating terminal of tank communicates with the initiating terminal of limbers, and the steel body boss that in the middle part of described steel body, outwardly formation play the guiding role, steel body boss is provided with oblique water hole.
Further, the lower surface of described steel body boss is inclined-plane, and oblique water hole extends to the inside wall of steel body from described inclined-plane.
Further, described inclined-plane is in vertical direction with 15 ° ~ 25 ° (preferably 20 °) angles.
Further, described oblique water hole is in vertical direction with 20 ° ~ 30 ° (preferably 25 °) angles.
Further, the section of described bit bottom lip surface is biconial.
Further, the quantity of described limbers is preferably three, is distributed in bit bottom lip surface.
Further, the quantity of described tank is also preferably three.
Cooling fluid can flow into drill bit internal (i.e. the hollow-core construction of steel body middle and upper part) by described oblique water hole, then bottom drill bit, (namely bottom steel body) flows out, and plays cooling and chip removal.
The utility model structure is simple, compact, low cost of manufacture.Use the drill bit of the utility model, this drill bit can directly be loaded on the interior pipe of rope drilling tool, therefore, when not promoting drilling rod, rope total cost management can be realized, until need more bit change time, also need not promote drilling rod, directly drill bit be renewed, be conducive to shortening and drill non-cutting time, improve drilling efficiency, reduce drilling cost, labour intensity is low.
Accompanying drawing explanation
Fig. 1 is the perspective view of the external convex rope total cost management drill bit of the steel of the utility model;
The top view that Fig. 2 is drill bit shown in Fig. 1;
Fig. 3 is the sectional view of drill bit shown in Fig. 1;
Fig. 4 is the use assembling drawing of drill bit shown in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
See Fig. 1, Fig. 2 and Fig. 3, the external convex rope total cost management drill bit of a kind of steel used for geological prospecting, comprise steel body 2, carcass is provided with above steel body 2, be hollow-core construction to steel body 2 middle and upper part bottom described steel body 2, the outer face of carcass is bit bottom lip surface 1, bit bottom lip surface 1 has limbers 8, and the bearing of trend of limbers 8 is parallel with direction, drill bit axis; Bit bottom lip surface 1 also has tank 3, described tank 3 extends to steel body 2 external surface from the center of bit bottom lip surface 1 along bit bottom lip surface 1, the initiating terminal of tank 3 communicates with the initiating terminal of limbers 8, the steel body boss 4 that in the middle part of described steel body 2, outwardly formation play the guiding role, steel body boss 4 is provided with oblique water hole 6.
The lower surface of described steel body boss 4 is inclined-plane 5, and oblique water hole 6 extends to the inside wall of steel body 2 from described inclined-plane.
Described inclined-plane 5 in vertical direction with 20 ° of angles, as shown in " Q " in Fig. 3.
Described oblique water hole 6 in vertical direction with 25 ° of angles, as shown in " R " in Fig. 3.
The section of described bit bottom lip surface 1 is biconial.
The quantity of described limbers 8 is three, is distributed in bit bottom lip surface 1.
The quantity of described tank 3 is also three.
Cooling fluid can flow into drill bit internal (i.e. the hollow-core construction of steel body middle and upper part) by described oblique water hole 6, then (namely bottom steel body) flows out bottom drill bit, plays cooling and chip removal.Use the drill bit of the utility model, this drill bit can directly be loaded on the interior pipe 9 of rope drilling tool (see in Fig. 4, Fig. 4, label 9 represents the interior pipe of rope drilling tool, and label 10 represents the outer tube of rope drilling tool), therefore, when not promoting drilling rod, rope total cost management can be realized, until need more bit change time, also drilling rod need not be promoted, directly drill bit is renewed, be conducive to shortening and drill non-cutting time, improve drilling efficiency, reduce drilling cost, labour intensity is low.
Above detailed introduction is done to a kind of preferred embodiment of the present utility model.Described detailed description of the invention just understands core concept of the present utility model for helping.It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify the protection domain also belonging to the utility model claim.
