Description
Technical field
The present invention relates to Construction Technology field, a kind of specifically drilling tool of four wings alloy bit.
Background technology
With my economic fast development, the continuous expansion of city size, the continuous reinforcement utilized to the underground space,
Deep-foundation pit engineering and Geotechnical Engineering are also more and more.Enter rock drilling tool because of its convenient construction, speed, need not largely work
Power, current market widely uses the drilling tools such as three leaf drill bits and down-hole hammer.But because three leaf drill bits are employed commonly on material
Steel, cause to wear no resistance and the proportion of goods damageds are very high, can only be constructed in general soil property region, it is impossible to carry out into rock drilling, it is necessary to
Construction operation could be continued by changing down-hole hammer.But down-the-hole hangs down and can not applied in general soil property, and down-hole hammer is made in deep hole
Shake larger during industry, soil layer, which easily caves in, behind drill bit causes down-hole hammer to be embedded in hole, can only be whole in combination with set pipe construction
Individual work progress process is numerous and diverse, and mechanical loss rate is high, and cost is larger.Therefore, the need in order to promote quickening site operation progress
And construction cost is reduced, find a kind of more easily construction method and be particularly important.
The content of the invention
Present invention mainly solves the drill high loss into rock, high cost, process of traditional drilling tool in land and rock combination geological is numerous
Miscellaneous, efficiency is low and can not tackle the uncertain problem of some ground, and there is provided one kind side on the premise of not increase expense
Just, four wing alloy bits efficiently, inexpensive and durable.
To achieve these goals, a kind of drilling tool of four wings alloy bit, including annular fixed seat, described ring are devised
Shape fixed seat by annular connecting portion suitable for reading, under the symmetrical otch of intraoral threaded joints and middle part constitute, lower mouth threaded joints
Inside is used for jointed rod for screw thread hollow and in a concave shape.
Four described wing alloy bits are provided with drill bit inclined-plane sword, and drill bit inclined-plane sword is by cutting edge and anistree alloy welding hole group
Into being uniformly distributed anistree alloy welding hole on cutting edge.
Four described wing alloy bits are provided with anistree carbide button, and anistree alloy tooth outline is that eight prisms are suitable for reading into 25 ° of otch.
Four described wing alloy bits are provided with alloy chisel teeth, and alloy wedge shape tooth outline combines shape with cylinder in circular cone, circle
Bore suitable for reading wedge shaped.
Compared with the existing technology, cutting principle of the present invention is by several carbide button heads, similar tooth to patent of the present invention
The broken rock that bites equally is carried out to rock mass, drag reduction and cooling are lubricated by the water injection hole injected clear water of annular fixed seat end,
Overall tapered, the contact surface for cutting rock mass is big, and cutting speed is fast, it is adaptable to the larger drilling in aperture, the advantage is that：This brill
Tool is provided with four drill bit inclined-plane swords, and cutting edge is provided with anistree carbide button, and anistree carbide button is suitable for reading consistent towards native face is met, simultaneously
Top is provided with an alloy chisel teeth, enhances the efficiency that drill bit enters rock, has greatly reinforced its durability, reduces mechanical damage
Consumption rate, reduces production cost.
Brief description of the drawings
Fig. 1 is the floor map of the present invention.
Fig. 2 is the top view of the present invention.
In figure：1. the drill bit inclined-plane sword of 3. alloy chisel teeth of anistree 2. annular fixed seat of carbide button 4..
Embodiment
