Abstract
The utility model discloses a kind of diamond compact bits, including shank, bit matrix, diamond compact, the upper surface of the shank is evenly arranged several bit matrix around its center, and the diamond compact is arc-shaped to be arranged at the top of the front end face for being welded on bit matrix；The upper surface edge chamfering of the shank；Main channel is vertically arranged in the shank, the main channel is connected to by bypassing water channel with chamfering surface.Advantage is the utility model drilling section using diamond compact, the wear-resisting property of drill bit is set to be greatly improved compared with carbide drill, in order to increase the ability for boring high rigidity rock stratum, the arc-shaped arrangement of diamond compact, it is first contacted with rock stratum when drilling positioned at the diamond compact of arc top, therefore bigger cutting force can be generated in drill end, enhance its drilling ability.The utility model can be matched with roof-bolter, hydraulic drill rig, adapt to the Rock penetrating of F≤12.
Description
Technical field
The utility model relates to drilling tool technical field, in particular to a kind of diamond compact bit.
Background technique
In the work progress of drilling engineering, it is frequently encountered harder rock stratum, since general planar cloth tooth bores
Its drill bit of head is contacted with rock stratum simultaneously, causes its pressure smaller, and drilling ability is weaker, therefore its efficiency for creeping into competent bed is just
It can reduce, can deposit around drill bit many drilling cuttings during drilling, if cannot clear up away in time, also result in drilling work
Progress.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of stronger diamond compact bits of drilling ability.
The technical solution of the utility model are as follows:
A kind of diamond compact bit, including shank, bit matrix, diamond compact, the upper surface of the shank
Several bit matrix are evenly arranged around its center, the diamond compact is arc-shaped to arrange the front end for being welded on bit matrix
At the top of face；The upper surface edge chamfering of the shank；Main channel is vertically arranged in the shank, the main channel passes through side
Road water channel is connected to chamfering surface.
Further, screw hole is opened up in shank.
Further, the angle of chamfering and horizontal plane is between 30 ° -45 °.
Further, bit matrix is at least three.
Further, the diamond compact installed on bit matrix is at least three.
The utility model has the beneficial effect that
The utility model drilling section uses diamond compact, obtains the wear-resisting property of drill bit compared with carbide drill
It increases substantially, in order to increase the ability for boring high rigidity rock stratum, diamond compact arc-shaped arrangement is located at arc most when drilling
The diamond compact at top is first contacted with rock stratum, therefore bigger cutting force can be generated in drill end, enhances its drilling
Ability.The utility model can be matched with roof-bolter, hydraulic drill rig, adapt to the Rock penetrating of F≤12.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is that the A-A in Fig. 1 rotates cross-sectional structure schematic diagram.
In figure: 1- shank, 11- screw hole, 12- main channel, 13- chamfering, 14- bypass water channel, 2- bit matrix, 3- diamond
Composite sheet.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
It is as shown in Figs. 1-2:
A kind of diamond compact bit, including shank 1, bit matrix 2, diamond compact 3, the shank 1 it is upper
End face is evenly arranged several bit matrix 2 around its center, and the arc-shaped arrangement of diamond compact 3 is welded on bit matrix
At the top of 2 front end face；The upper surface edge chamfering 13 of the shank 1；Main channel 12, institute are vertically arranged in the shank 1
It states main channel 12 and is connected to by bypassing water channel 14 with 13 surface of chamfering.
Specifically, connection and more bit change, drill bit open up screw hole 11 using being threadedly coupled in shank 1 for convenience.
Specifically, in order to turn well liquid or cleaning solution drilling can be conducive to from preferable angle impacts diamond compact 3
The angle of the progress of operation, chamfering 13 and horizontal plane is preferably between 30 ° -45 °.
Specifically, bit matrix 2 is at least three.
Specifically, the diamond compact 3 installed on bit matrix 2 is at least three.
The utility model drilling section uses diamond compact, obtains the wear-resisting property of drill bit compared with carbide drill
It increases substantially, in order to increase the ability for boring high rigidity rock stratum, the arc-shaped arrangement of diamond compact 3 is located at arc when drilling
The diamond compact 3 of top is first contacted with rock stratum, therefore bigger cutting force can be generated in drill end, enhances its brill
Into ability, while it being also provided with bypass water channel 14, drilling fluid is introduced the main channel 12 of drill bit by the channel in drilling rod, then passed through
Bypass water channel 14 constantly washes out the clast of drill bit side generation, conducive to the progress of drilling work, while may be drill bit
Cooling.The utility model can be matched with roof-bolter, hydraulic drill rig, adapt to the Rock penetrating of F≤12.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
