Description
Technical field
This utility model belongs to bit technique field, is specifically related to a kind of percussion drilling plate.
Background technology
Drill bit is to be made up of the drilling rod of cylindricality and the blade being fixed on drilling rod top, and the impact blade of prior art includes cutter
Sheet body, is provided with left cutting edge and the V-type cutting portion of right cutting edge composition on the top of described blade body, and its end section is flat
Face directly, offer locating slot convenient use at the middle part of blade body, although it can meet the demand in certain market, but
It is after locating slot has been offered at middle part, made the insufficient strength in the middle part of blade body, is susceptible to fracture in use, thus affects
The service life of drill bit, the suitability and practicality are restricted.
Summary of the invention
The percussion drilling plate that the purpose of this utility model is to provide a kind of simple in construction, stability in use is good and the suitability is strong.
The technical scheme realizing this utility model purpose is a kind of percussion drilling plate, including blade body, at described blade originally
The top of body is provided with left cutting edge and right cutting edge, and the center bottom in described blade body is provided with locating slot, in described location
Being uniformly provided with vertical convex tendon in the sidewall of groove, the inwall at described locating slot is also uniformly provided with connection ring muscle, described vertical convex tendon
Being connected the staggered fixing connection of ring muscle with described, be additionally provided with arrived tableting on the inwall of described locating slot, described arrived tableting is arranged on
Vertical convex tendon with in the space being connected between ring muscle.
The projection muscle bar for being connected to drilling rod end face also it is uniformly provided with in the bottom of described blade body.
It is provided with clamping groove on the surface of described vertical convex tendon and connection ring muscle.
The bottom cross sectional shape of described blade body is inverted cone.
This utility model has positive effect: simple in construction of the present utility model, stability in use are good, in locating slot
It is provided with connection ring muscle and vertical convex tendon, thus can effectively ensure intensity and the toughness of locating slot, thus can effectively ensure cutter
The service life of sheet and stability in use, reduce production cost, and the suitability is strong and practicality good.
