Abstract
The invention relates to a well digging drill bit.Drill teeth are inlaid on a drill bit body.A drill bit coat is fixed to the surface of the drill bit body except the drill teeth.The well digging drill bit is simple in structure and long in service life.
Description
Technical field
The invention belongs to drill bit, particularly to the drill bit of a kind of well-digging.
Background technology
In freezing borehole work progress, the service efficiency improving drill bit is to reduce construction cost important factor in order, and the bit wear used in construction is serious, if be continuing with, it will affecting speed of application, schedule delays, will increase construction cost if do not used.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention provides a kind of well drill.Its simple in construction, long service life.
This invention address that its technical problem is adopted the technical scheme that: bit body is inlayed brill tooth, the bit body surface except boring tooth is fixed with drill bit clothing.
Present configuration is simple, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
As it is shown in figure 1, bit body 2 is inlayed brill tooth 3, bit body 2 surface except boring tooth 3 is fixed with drill bit clothing 4.
Described drill bit clothing 4 is evenly equipped with welding hole 1, is welded and fixed by welding hole 1 between drill bit clothing 4 and bit body 2.
Described drill bit clothing 4 wall thickness is 5-10 millimeter.
When boring tooth 3 worn drill bit and being not sharp, remove drill bit clothing 4, it is possible to be continuing with.
Claims (3)
1. a well drill, it is characterised in that: bit body (2) is inlayed brill tooth (3), bit body (2) surface except boring tooth (3) is fixed with drill bit clothing (4).
2. well drill according to claim 1, it is characterized in that: described drill bit clothing (4) is evenly equipped with welding hole (1), be welded and fixed by welding hole (1) between drill bit clothing (4) and bit body (2).
3. well drill according to claim 1, it is characterised in that: described drill bit clothing (4) wall thickness is 5-10 millimeter.
