The invention discloses a kind of staged Percusion spiral drill head, six square joints are fixed on Percusion spiral drill bar by using pin, nut, split pin, holding screw outward;Impactor is threaded togather with outer six square joint by API;Support set is lined between impactor and Percusion spiral drill bar;Helical blade is welded with Percusion spiral drill bar and is had angle with augers central axis with tooth, the anterior tooth distributing line that bores of helical blade is bored, tapered arrangement;The bore bit tooth that bores anterior with Percusion spiral drill bar in impactor bottom has a difference in height, stepped, during bore operation, first by impactor broken rock, forms free face, then carries out stripping drilling by the brill tooth on helical blade, greatly improves drilling efficiency.

Description

A kind of staged Percusion spiral drill head
Technical field
The present invention relates to a kind of Percusion spiral drill head, and in particular to a kind of staged Percusion spiral drill head, it is suitable to bored concrete pile Basic hole construction, its distinctive staged flat side of a hammer structure and brill tooth tapered arrangement, greatly improve drilling efficiency.
Background technology
In bored pile construction, due to the complexity of geological conditions, severely-weathered, middle weathering or even gentle breeze base are run into During rock stratum, if will still be met difficulty using conventional engineering method and drilling tool, often drilling depth is slow, in addition at all cannot drilling depth, no Only construction cost is high, and construction quality is difficult to ensure that.With this understanding, piling machinery also becomes varied into hole drill tool, There is cylinder to bore, struggle against the forms such as brill, auger, down-hole hammer, subdivision is up to tens of kinds.Conventional helical drill bit, mainly including drill body, Helical blade, brill tooth, apply in general to all kinds of weak soil property stratum, and being oriented to deslagging by the cutting and helical blade of boring tooth realizes Drilling.For lithostratigraphy, conventional augers cannot be crept into, mainly with impact drill, churning driven, down-hole hammer etc. Method.Impact drill relies on drill hammer gravitational thrusts rock crushing pore-forming, and the method is original, efficiency is low, seriously polluted;Churning driven Bored to destroy rock mass by way of being ground configuring cylinder, and pore-forming is realized with the brill borehole cleaning that struggles against, the method efficiency is high compared with impact drill, but Under the conditions of hard rock it is inefficient and bore odontotripsis it is violent;Down-hole hammer is a kind of Hydro-Hammer Drilling Tool, in the driving of compressed air Lower impact cutting detritus body drilling, enters rock efficiently, but equipment backstage typically configures many air compressor machines of high-pressure high-flow, and power consumption is big.
The content of the invention
The technical problems to be solved by the invention be to provide one kind drill into rock efficiency high, can meet various geological conditions and The low staged Percusion spiral drill head of energy consumption.
In order to solve the above-mentioned technical problem, the staged Percusion spiral drill head that the present invention is provided, including Percusion spiral drill bar, Helical blade, tooth and impactor are bored, the distributing line and described impact spiral shell of the anterior described brill tooth of described helical blade The central axis of rotary drill bar is at an angle, tapered arrangement.
The angle that the described distributing line of brill tooth is formed with the central axis of described Percusion spiral drill bar is less than 180 °.
Described brill tooth closest to described impactor has a difference in height with the bottom bore bit of described impactor, in rank Scalariform.
The described tooth that bores closest to described impactor is more than pricker with the difference in height of the bottom bore bit of described impactor Grease head highness.
Outer six square joint is installed on described Percusion spiral drill bar by pin, nut, split pin and holding screw.
Described impactor is threadedly attached on described outer six square joint, described impactor and described impact Support set is lined between auger stem.The impact reactive force of impactor can be mitigated, and play certralizing ability.
Using the staged Percusion spiral drill head of above-mentioned technical proposal, compared with prior art, the helical blade on drilling rod Front portion brill tooth distributing line is at an angle with augers central axis, tapered arrangement;Bore tooth has one with impactor bottom bore bit Difference in height, it is stepped;During bore operation, impactor touches scar first, and broken rock produces cavity and crack, formed Free face, then stripping drilling is carried out by the brill tooth of the upper conical arrangement of helical blade, rate of penetration is largely increased.
In sum, the present invention is a kind of to drill into rock efficiency high, can meet various geological conditions and the low ladder of energy consumption Formula Percusion spiral drill head.
Brief description of the drawings
Fig. 1 is staged Percusion spiral drill head overall structure view.
Label in figure:1- Percusion spiral drill bars, 2- helical blades, 3- bores tooth, outer six square joints of 4-, 5- holding screws, 6- Pin, 7- nuts, 8- split pins, 9- support sets, 10- impactors.
Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment with the present invention is described in further detail.
Referring to Fig. 1, during outer six square joint 4 penetrated into Percusion spiral drill bar 1, with holding screw 5, pin 6, nut 7, opening Pin 8 is fixed, and prevents from coming off.Outer six square joint 4 is coordinated with Percusion spiral drill bar 1 by six aspects, carries out transmission torsion Square;Support set 9 is pressed into Percusion spiral drill bar 1, then impactor 10 penetrated into support set 9, and connected by API screw threads It is connected on outer six square joints 4.In boring procedure, support set 9 can alleviate the impact shock reaction force of impactor 10, and extension is bored The service life of tool.Helical blade 2 is welded with Percusion spiral drill bar 1 and tooth 3 is bored, the rock particles after crushing can be in helical-blade Under piece, compressed gas booster action, quick deslagging;The distributing line for boring tooth 3 has angle with the central axis of Percusion spiral drill bar 1, Tapered arrangement, reduces cutting force, is conducive to the drilling of drill bit.Brill on the bottom bore bit of impactor 10 and Percusion spiral drill bar 1 Tooth 3 has a difference in height, stepped, impactor 10 is first impacted scar, destroys the globality of rock stratum, forms free face, allows brill The rock that enters of tooth 3 is more prone to, and improves drilling efficiency.Further according to geological condition and pore-forming size, by different structure size knot The augers and impactor of structure can be combined configuration, it is adaptable to efficient, inexpensive, the low energy consumption drilling and forming hole of bad ground.
Specifically, the angle that the central axis of the distributing line and Percusion spiral drill bar 1 that bore tooth 3 is formed is less than 180 °.
Tooth 3 is bored closest to impactor 10 with the difference in height of the bottom bore bit of impactor 10 more than bore bit highly.
The preferred embodiments of the present invention are these are only, the present invention is limited never in any form, for this area For technical staff, the present invention can have various changes and modification.It is all within the spirit and principles in the present invention, made it is any Change, equivalent, modification, improvement etc., should be included within the scope of the present invention.Therefore, protection model of the invention Enclosing should be defined by the protection domain of claims.
