Abstract
The application belongs to machining drilling equipment, specially a kind of anti-to bury core drill, including drill bit and drilling rod, and the side of the drilling rod and drill bit junction is equipped with cutter device.
Description
Technical field
The application belongs to machining drilling equipment, specially a kind of to prevent burying core drill.
Background technique
The screw damage having in underground equipment use process can not fasten, belt spillplate, raking loader connecting portion pine
The constructions such as dynamic, rail joint docking require live perforating and fix, and traditional mode is that underground is freezed or by well in equipment replacement
Repair, underground, which is freezed, to be brought great potential safety hazard, and consuming time is long for upper well servicing, thus we study made it is portable
Formula small drilling machine efficiently solves the practical problem at scene.
Summary of the invention
In order to solve the above-mentioned technical problem, prevent burying core drill this application provides one kind, the application is to pass through following proposal
It realizes:
One kind is anti-to bury core drill, including drill bit and drilling rod, and the side of the drilling rod and drill bit junction is equipped with cutter device.
Preferably, the cutter device is diamond compound cuts piece.
Preferably, one end of the diamond compound cuts piece is equipped with fixing axle, and the bottom of the drill bit is equipped with and fixation
The fixation blind hole that axis matches.
Preferably, the side of the fixing axle is equipped with blind hole, and the side of the drill bit is equipped with the screw thread matched with blind hole
Hole, the solid blind hole when fixing in blind hole of fixing axle are overlapped with the center line of threaded hole.
Preferably, the diamond compound cuts piece includes cutting sheet ontology and the cutting positioned at cutting sheet ontology front end
Sword.
Preferably, the cutting edge is equipped with diamond particles.
Preferably, the edge of the cutting edge is equipped with " V " type groove.
The utility model has the advantages that cutting and crushing will be played the role of to coal and rock by being equipped with diamond compound cuts piece, drilling is swept again
Hole can smoothly propose drill bit, not only save a set of drill bit, drilling rod, and remain drilling and can continue to using each collapsing
Estimated ten thousand yuan of the cost-saved 4-5 of hole drilling.
Detailed description of the invention
Fig. 1 is the embodiment of the present application structural schematic diagram；
Fig. 2 is the structural schematic diagram of the embodiment of the present application cutter device；
In figure, 1, drill bit, 2, drilling rod, 3, diamond compound cuts piece, 4, fixing axle, 5, blind hole, 6, cutting sheet ontology, 7,
Cutting edge, 8, V-groove, 9, threaded hole.
