Abstract
The utility model belongs to the technical field of the technique of drill bit for the geological survey and specifically relates to a deep hole hard rock probing polycrystalline diamond compact drill bit, including the drill bit base member, blade holder, diamond compact piece sword tooth and nozzle are fixed with 4 blade holders on the drill bit base member, are equipped with the compound piece sword tooth of 5 hard rocks on the blade holder, and the distance that compound piece sword tooth exposes the blade holder on the blade holder is 3 centimetres, and the contained angle of 2 adjacent blade holders is 145 in the every hemicycle of drill bit base member, has still seted up a 3 -5 nozzle on the drill bit base member terminal surface. The utility model discloses be equipped with 4 blade holders, on the base member in 2 semicircles the contained angle of 2 adjacent blade holders be 145, improved the drilling speed of drill bit greatly, the distance that diamond compact piece sword tooth on the blade holder exposes the blade holder is 3 centimetres, furthest's reduction the volume wearing and tearing volume of compound piece sword tooth, improved the wearability and the shock resistance of diamond compact piece greatly, improved the broken dynamics of drill bit deep hole hard rock.
Description
Technical field
This utility model relates to the technical field of geologic prospect drill bit, especially a kind of deep hole hard rock probing polycrystalline diamond compact bit.
Background technology
Probing is irreplaceable means in geology of deep part miner work, currently used drill bit upper cutter head is uniformly distributed along bit matrix, and the diamond blade on tool rest is completely out of tool rest, when diamond bit creeps into solid rock, low after bit speed elder generation height, and quick abrasion, go out sword amount big, cutting force is little, and drill bit is easy to damage, and greatly reduces work quality and speed.
Utility model content
In order to overcome the deficiency of existing technology, this utility model provides a kind of deep hole hard rock probing polycrystalline diamond compact bit.
This utility model solves its technical problem and be the technical scheme is that a kind of deep hole hard rock probing polycrystalline diamond compact bit, including bit matrix, tool rest, composite polycrystal-diamond cutter tooth and nozzle, 4 tool rests it are fixed with on described bit matrix end face, described each tool rest is provided with 3-8 sheet composite polycrystal-diamond cutter tooth, on described bit matrix end face, the angle between adjacent 2 tool rests in upper hemicycle is 145 °, the angle between adjacent 2 tool rests in the described upper and lower hemicycle of bit matrix end face is 145 °, it is further opened with 3-5 nozzle on described bit matrix end face.
According to another embodiment of the present utility model, farther include described each tool rest and be provided with 5 composite polycrystal-diamond cutters tooth.
According to another embodiment of the present utility model, farther include every composite polycrystal-diamond cutter tooth on described each tool rest exposing the distance of tool rest is 3 centimetres.
The beneficial effects of the utility model are, bit matrix is provided with 4 tool rests, on matrix, in 2 semicircles, the angle of adjacent 2 tool rests is 145 °, substantially increase the drilling speed of drill bit, it is 3 centimetres that diamond compact cutter tooth on tool rest exposes the distance of tool rest, reduce the volume wear of composite sheet cutter tooth to greatest extent, substantially increase wearability and the impact resistance of diamond compact, improve the broken dynamics of drill bit deep hole hard rock.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
1. bit matrix in figure, 2. tool rest, 3. cutter tooth, 4. nozzle.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of deep hole hard rock probing polycrystalline diamond compact bit, including bit matrix 1, tool rest 2, composite polycrystal-diamond cutter tooth 3 and nozzle 4,4 tool rests 2 it are fixed with on bit matrix 1 end face, each tool rest 2 is provided with 3-8 sheet composite polycrystal-diamond cutter tooth 3, on bit matrix 1 end face, the angle between adjacent 2 tool rests 2 in upper hemicycle is 145 °, the angle between adjacent 2 tool rests 2 in the upper and lower hemicycle of bit matrix 1 end face is 145 °, and bit matrix 1 end face is further opened with 3-5 nozzle 4.Preferably, each tool rest 2 is provided with 5 composite polycrystal-diamond cutters tooth 3.It is 3 centimetres that every composite polycrystal-diamond cutter tooth 3 on each tool rest 2 exposes the distance of tool rest 2.
This utility model is provided with 4 tool rests at bit matrix, on bit matrix, in 2 semicircles, the angle of adjacent 2 tool rests is 145 °, substantially increase the drilling speed of drill bit, it is 3 centimetres that diamond compact cutter tooth on tool rest exposes the distance of tool rest, reduce the volume wear of composite polycrystal-diamond cutter tooth to greatest extent, substantially increase wearability and the impact resistance of diamond compact, improve the broken dynamics of drill bit deep hole hard rock.
