Abstract
The utility model is a kind of Combined screw thread drilling rod, the drilling rod being related in building field pile machine equipment, its auger leaf（2）With screw body（1）Between can dismantle, each auger leaf（2）Radian be no more than 1 π, thickness H is not less than 2 centimetres, and auger leaf（2）Inner side has for fixed groove（4）；There is square external screw thread on the outside of screw body（3）, the groove of its shape size and auger leaf coincide, to fix auger leaf.The advantages of the utility model is：1 is easy to maintain.Repair welding can be carried out without dismounting drilling rod with the new auger leaf of quick-replaceable when wearing, which occurs, in drilling tool needs maintenance, it is convenient and swift.2 is with strong points.The auger leaf of different in width is changed for various soil mass, to adjust the size of drilling internal thread, and then adjusts the pile soil stress ratio of pile body.
Description
Technical field
Screw-type stake machine field construction drilling rod is the utility model is related to, can be torn open between a kind of auger leaf and screw body
The Combined screw thread drilling rod unloaded.
Background technology
The patent No. 01250189.1 proposes a kind of drilling soil compaction and forms the threaded threaded drillpipe of hole wall, by screw rod and its
On auger leaf composition.But in actual applications there is following defect in the invention：1st, when being constructed in sand, land pebble not
It is evitable that serious abrasion can be caused to drilling tool, make that drill pipe diameter reduces, pore-forming can not meet design requirement, need during maintenance
Drilling rod is disassembled ability repair welding auger leaf, either dismounting drilling rod or repair welding, all wasted time and energy.2nd, no matter which kind of is native
Layer, the internal diameter and external diameter of auger leaf are fixed, and auger leaf external diameter size, specific aim can not be flexibly adjusted according to geological condition
Difference.
The patent No. 201510931696.4 proposes a kind of combined drill rod for twist bit, by multiple screw assemblies
Form with splined shaft, connected between screw assembly and splined shaft by spline.But in the middle part of drilling rod during a certain screw assembly damage,
Need all screw assemblies of dismounting drilling rod one end just to remove the screw assembly of damage, waste time and energy.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems in the prior art, there is provided a kind of Combined screw thread bores
Bar.
The utility model solve the above problems the technical scheme that uses for：A kind of Combined screw thread drilling rod, its auger leaf
It can be dismantled between screw body.
The radian of the auger leaf is no more than 1 π, and thickness is not less than 2 centimetres.
There is square groove on the inside of the auger leaf, with fixed brill leaf.
There is square external screw thread on the outside of the screw body, the groove of its shape size and auger leaf coincide, to fix spiral shell
Rotary drill leaf.
Screw connection can be passed through between auger leaf and screw body.
Spline can be set on the square externally threaded contact surface of groove and screw body of auger leaf, to reduce connecting screw
On shearing.
The advantages of the utility model, is as follows：(1) need dismounting drilling rod could be to auger leaf repair welding when conventional drill is maintained.
And the utility model is easy to maintain, can quick dismounting and change optional position auger leaf, without dismounting drilling rod and repair welding, side
Just it is quick.(2) the auger leaf of different in width can be changed according to different geological conditions, different pile peripheral earths, to adjust
The size of whole drilling internal thread, it is stronger to the specific aim of the soil body.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the screw body schematic diagram with spline.
Fig. 3 is the schematic diagram of the auger leaf of groove bands spline.
Fig. 4 is the profile of screw connection screw body and auger impeller structure.
In figure, 1 is screw body, and 2 be auger leaf, and 3 be the square external screw thread in screw body, and 4 be the square of auger leaf
Groove, 5 be the spline set in screw body, and 6 be the spline on auger leaf, and 7 be connection auger leaf and the screw of screw body.
Embodiment
As shown in figure 1, the utility model is a kind of Combined screw thread drilling rod, i.e. auger leaf（2）With screw body（1）Between
It can dismantle.Each auger leaf（2）Radian be no more than 1 π, thickness is not less than 2 centimetres, and has on the inside of auger leaf for solid
Fixed square groove（4）；There is square external screw thread on the outside of screw body（3）, the groove of its shape size and auger leaf（4）It coincide,
To fix auger leaf.As shown in Figures 2 and 3, spline can be set in screw body and auger leaf, to reduce connection spiral shell
Shear stress on silk.As shown in figure 4, auger leaf（2）With screw body（1）Between can pass through screw（7）Connection.
, can be with the new auger leaf of quick-replaceable when heavy wear, which occurs, in drilling tool needs maintenance（2）Bored without dismantling
Bar, without repair welding, it is simple and convenient.For the various soil mass of different engineerings, the auger leaf of different in width can be changed（2）, from
And the size of drilling internal thread is adjusted, and then adjust the pile soil stress ratio of pile body.
Claims (6)
