Abstract
The utility model discloses a kind of vane type reamers, including axle body, the left end of the axle body is equipped with axle body fixation hole, three groups of reaming blades are from left to right equipped on the axle body, reaming blade described in every group includes that staggered form is fixed at the semiellipse arc shaped blade of axle body upper and lower ends and is fixed at right half section of the alloy head of semiellipse arc vane tip, is symmetrically arranged with two foot bifurcation shape through-holes on the semiellipse arc shaped blade of two groups of reaming blades on the left of the axle body.The utility model optimizes reamer structure, using leaf structure, can be adapted for the use of Soft Soil Layer, is effectively ensured and expands aperture effect and quality, greatly improves production efficiency.
Description
Technical field
The utility model belongs to reamer technical field, and in particular to a kind of vane type reamer.
Background technique
Reamer is connected between diamond bit and basket, is played and is expanded aperture and finishing hole wall guarantee aperture not
A kind of drilling tool reduced.Since diamond bit diameter differs very little with the size of rock core pipe outside diameter, make hole wall and basket it
Between gap more reduce, so that water is obstructed, and easily cause bit freezing.Diamond reamer is a short cylinder tube body, upper and lower steel body
Part has screw thread to be connected respectively with drill bit and basket, and middle section is the diamantiferous carcass of covering, and outer diameter is slightly larger than gold
Hard rock bit diameter (2 millimeters or so) had water sink on carcass side surface, and passed through water flow.In the rock of extremely hard grindability
Layer, also has using two and multiple reamers, in addition to one mounted in the top of drill bit, remaining ask every ground be mounted in basket it
Between.
The reamer structure of the prior art is more single, for Soft Soil Layer reaming, can not effectively guarantee to expand
Aperture effect and quality.
Utility model content
The purpose of this utility model is to provide a kind of vane type reamers, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of vane type reamer, including axle body,
The left end of the axle body is equipped with axle body fixation hole, three groups of reaming blades is from left to right equipped on the axle body, described in every group
Reaming blade includes that staggered form is fixed at the semiellipse arc shaped blade of axle body upper and lower ends and is fixed at semiellipse arc
The alloy head that right half section of vane tip is symmetrically arranged on the semiellipse arc shaped blade of two groups of reaming blades on the left of the axle body
Two foot bifurcation shape through-holes.
Preferably, the axle body is hollow cylindrical housings.
Preferably, reaming the vane size described in three groups is sequentially reduced.
Preferably, the alloy head include the cylindrical portion being fixedly connected with semiellipse arc shaped blade and be set to cylindrical portion top
The tapered portion in portion.
The technical effect and advantage of the utility model: the vane type reamer optimizes reamer structure, using half
Ellipse arc leaf structure installs alloy head additional on semiellipse arc shaped blade, so that the reamer can be adapted for Soft Soil Layer
Use, can effectively ensure that and expand aperture effect and quality, greatly improve production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 axle body, 2 axle body fixation holes, 3 reaming blades, 4 semiellipse arc shaped blades, 5 alloy heads, 6 foot bifurcation shape through-holes.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of vane type reamer as shown in Figure 1, including axle body 1, the left end of the axle body 1
Equipped with axle body fixation hole 2, three groups of reaming blades 3, the packet of reaming blade 3 described in every group are from left to right equipped on the axle body 1
Staggered form is included to be fixed at the semiellipse arc shaped blade 4 of 1 upper and lower ends of axle body and be fixed at 4 top of semiellipse arc shaped blade
Right half section of alloy head 5 is symmetrically arranged with two on the semiellipse arc shaped blade 4 of two groups of reaming blades 3 in 1 left side of axle body
Foot bifurcation shape through-hole 6.
Specifically, the axle body 1 is hollow cylindrical housings.
Specifically, the size of reaming blade 3 described in three groups is sequentially reduced.
Specifically, the alloy head 5 include the cylindrical portion being fixedly connected with semiellipse arc shaped blade 4 and be set to cylindrical portion
The tapered portion at top.
The vane type reamer, optimizes reamer structure, using semiellipse arc leaf structure, in semiellipse
Alloy head is installed additional on arc shaped blade 4, so that the reamer can be adapted for the use of Soft Soil Layer, be can effectively ensure that and is expanded aperture
Effect and quality, greatly improve production efficiency.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
