Description
Technical field
The utility model relates to and enters used drill bit for department's bolting with wire mesh hole drills such as mine water power, traffic, is specially a kind of polycrystalline diamond both wings half anchor bit.
Background technology
At underground coal mine, owing to wanting the gas in extraction coal seam, gas discharge channel is blocked in order to prevent borehole wall from caving in, ensure that gas can be extracted out smoothly, in boring, generally to adopt down the sleeve pipe of guard aperture, traditional method is by after bit drills bar drill to precalculated position, setting of casing again, but because drill bit is solid construction, drill bit and drilling rod ability setting of casing must be taken out, therefore in the process of boring, destroy the stability of hole wall, cause the rock falls blocking boring on hole wall, precalculated position can not be arrived by under sleeve pipe, the methane gas under mine cannot be extracted smoothly out, along with the increasing of the infrastructure dynamics such as tunnel traffic, bolt support is the most economical effective method of one improving geotechnical engineering stability.
Utility model content
The utility model provides a kind of polycrystalline diamond both wings half anchor bit, to solve the problem proposed in above-mentioned background technology.
A kind of polycrystalline diamond both wings half anchor bit, comprise: spiral drill body, cutting edge, hollow drill body mouth, chip area, cutting rear edge face, cutting alloy sword face, alloy sword groove, described spiral drill body head arranges two cutting edges, is provided with hollow drill body mouth in the middle of drill body.
Described drill body has chip area, between two cutting edge portion rotational trajectories, forms chip area.
Described cutting edge be solid structure multiaspect composition, after cutting edge for cut rear edge face, before be provided with cutting alloy sword face.
Described cutting alloy sword face is poly-golden diamond material, arranges in alloy sword groove on the cutting edge.
Described alloy sword groove and cutting edge form miter angle slope.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, be hollow spiral drilling bit, are made up of poly-golden diamond, sturdy and durable, are easy to universal and use.
Accompanying drawing explanation
Fig. 1 is front view schematic diagram of the present utility model.
Fig. 2 is top view schematic diagram of the present utility model.
Detailed description of the invention
