Utility model content
The utility model is above-mentioned in order to overcome the shortcomings of, provides a kind of drill bit of rotary drilling rig, including enclosure body, described
Enclosure body outer ring is equipped with several circles and helps brill item, described that brill item is helped to include first body and Article 2 body, first body and second
Hollow interlayer is equipped between body, interlayer is arranged with the connection for connecting first body and Article 2 body in both sides up and down
Block, end section is taper under first body and Article 2 body, and first body passes through several enclosure bodies that are threaded in
Outer ring.
Preferably, first body and the setting of Article 2 body uniform thickness.
Preferably, each helps a brill surface to be equipped with ceramic wear-resisting particle.
Preferably, first body, Article 2 body and two link block integrated settings.
The utility model has the beneficial effects that：By helping the pyramidal structure for boring two body lower ends on item that drill bit is facilitated to revolve
It digs, by hollow interlayer casting, is connected through a screw thread, replacement easy to disassemble, reasonable design is suitble to promote the use of.
Description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is the principal sketches of the utility model.
