Abstract
The utility model discloses a kind of wear-resisting diamond compact bits, it is characterized by comprising bit bodys and threaded rod, the bit body and threaded rod are an integral structure, the bit body is equipped with diamond compact, water outlet is equipped at the top of the bit body, filter screen is equipped in the water outlet, bit body outer arc face is equipped with wear-resistant block, and the outer surface of the diamond compact is concordant with bit body outer arc face is cut.Originally practical to have the advantages that by being uniformly coated with wear-resistant block on the outer surface of diamond compact, it is more wear-resisting than steel due to being made of alloy, it is more durable, it can effectively slow down abrasion, improve the service life of diamond compact bit entirety.
Description
Technical field
The utility model relates to bit technique field, in particular to a kind of wear-resisting diamond compact bits.
Background technique
The drill bit of down hole drill high speed operating and the friction of rock stratum fierceness cause different degrees of damage to drill bit and break
Bad, in existing practical down hole drill, what is generallyd use is in the upper high-intensitive and high abrasion of the cutting pawl front end of drill bit welding
Diamond compact is used to be drilled, and this kind of drill bit is in use, although the strong hardness of diamond compact is high, drilling
Efficiency is also promoted therewith, also will appear abrasion, this has seriously affected the service life of diamond compact bit entirety.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technical problem, provides a kind of wear-resisting diamond compact
Drill bit.
In order to solve the above technical problems, technical solution provided by the utility model is a kind of wear-resisting diamond compact drilling
Head, it is characterised in that: including bit body and threaded rod, the bit body and threaded rod are an integral structure, on the bit body
Equipped with diamond compact, it is equipped with water outlet at the top of the bit body, is equipped with filter screen in the water outlet, outside the bit body
Side arc surface is equipped with wear-resistant block, and the outer surface of the diamond compact is concordant with bit body outer arc face.
Preferably, the shape of the diamond compact is circle, and quantity is 1-3.
Preferably, the wear-resistant block is made of alloy material, and the outer surface of the wear-resistant block is higher than bit body outer arc
The horizontal plane in face.
The utility model is had the advantages that compared with prior art by uniform on the outer surface of diamond compact
Wear-resistant block is coated, it is more wear-resisting than steel due to being made of alloy, it is more durable, it can effectively slow down abrasion, improve diamond
The service life of compact bit entirety.
Detailed description of the invention
Fig. 1 is a kind of wear-resisting diamond compact bit structural schematic diagram of the utility model.
Fig. 2 is a kind of wear-resisting diamond compact bit structure top view of the utility model.
It is as shown in the figure: 1, bit body, 2, threaded rod, 3, diamond compact, 4, water outlet, 5, wear-resistant block.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with attached drawing, a kind of wear-resisting diamond compact bit, it is characterised in that: including bit body 1 and threaded rod 2, institute
It states bit body 1 and threaded rod 2 is an integral structure, the bit body 1 is equipped with diamond compact 3,1 top of bit body
Equipped with water outlet 4, filter screen is equipped in the water outlet 4, the 1 outer arc face of bit body is equipped with wear-resistant block 5, the gold
The outer surface of hard rock composite sheet 3 is concordant with 1 outer arc face of bit body.
The shape of the diamond compact 3 is circle, and quantity is 1-3.
The wear-resistant block 5 is made of alloy material, and the outer surface of the wear-resistant block 5 is higher than the water in bit body outer arc face
Plane.
The utility model is higher than bit body by being equipped with wear-resistant block, the outer surface of wear-resistant block on bit body outer arc face
The horizontal plane in outer arc face, and have alloy material to be made, can effectively slow down abrasion, and the filter screen in water outlet can be with
The impurity in cooling water is filtered, the service life of diamond compact bit entirety, and the appearance of diamond compact are improved
Face is concordant with bit body outer arc face is cut, it is possible to avoid causing bit body poly-injury, the number of diamond compact
Amount can be selected according to actual use demand.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing
Be also one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field
Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with
The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
