Abstract
The utility model is related to drill bit, and in particular to combined type reaming bit, belongs to drilling tool equipment technical field.It includes setting female drill bit（1）, reaming bit（3）, one end be provided with external screw thread（2）The other end is provided with internal thread（5）Guided connector（4）, reaming bit（3）With guided connector（4）Connected by taper, drill bit（1）With guided connector（4）It is provided with external screw thread（2）One end connection, guided connector（4）Female one end is set and externally threaded drilling rod is provided with（6）Connection.Compared with prior art, the utility model has the advantages that：Original starter instead of using conventional bit plus guided connector combination, convenient and flexible installation, drill bit can just be unloaded from the external screw thread of guided connector one end without the use of specific purpose tool and be changed or reconditioning, production cost is significantly reduced while improve production efficiency.
Description
Technical field
The utility model is related to drill bit, and in particular to combined type reaming bit, belongs to drilling tool equipment technical field.
Background technology
With highway, the energy, infrastructure construction dynamics increasing, in energy extraction, underground foundation Facilities Construction, expand
Drill is due to the design feature of its own, and application prospect is more and more extensive；At present in the supporting in tunnel, infrastructure projects
In the application such as pipeline laying, because of geological structure and the particularity of construction, need to be drilled using borehole-enlarging drilling tool；In the borehole, lead
To drill bit elder generation one pilot hole of Drilling, play positioning and be easy to use reaming bit reaming, be conducive to being smoothed out for drilling.Mesh
Before, the reaming bit that in the market is used is assembled by a starter and a reaming bit combination.Creeping into
Cheng Zhong, because simultaneously starter plays a part of to draw brill and is oriented to, can wear and tear because geological structure is complicated different with use environment
Aggravation is directly damaged, and need to be taken pricker instrument and could be unloaded reaming bit using special when changing starter, and it has brill
The problems such as head changes inconvenient, drilling efficiency is low.
Utility model content
In order to overcome defect present in prior art, the purpose of this utility model is to provide a kind of simple structure, no
Need to take pricker instrument and can just be convenient for changing drill bit, drilling efficiency combined type reaming bit high using special.
To achieve these goals, the utility model uses following technical scheme：Combined type reaming bit, including be provided with
The drill bit of internal thread, reaming bit, one end are provided with the external screw thread other end and set female guided connector, reaming bit
It is connected by taper with guided connector, drill bit is provided with externally threaded one end and is connected with guided connector, and guided connector sets
Put female one end and be connected with externally threaded drilling rod is provided with.
The utility model has the advantages that due to using above technical scheme：Using conventional bit plus the company of guiding
Connect device combination and instead of original starter, convenient and flexible installation, in drilling process, when conventional bit is damaged or is needed
When carrying out reconditioning, conventional bit can be just unloaded from the external screw thread of guided connector one end without the use of specific purpose tool is carried out more
Change or reconditioning, need not also change guided connector, not only increase production efficiency, while also making production cost obtain significantly
Reduction；Additionally, conventional bit can also be directly connected to drilling rod carries out Drilling so that operation is more convenient, flexible, drilling work is given
Bring facility.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
In figure：Drill bit 1, external screw thread 2, reaming bit 3, guided connector 4, internal thread 5, drilling rod 6.
Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings：
As shown in figure 1, combined type reaming bit, including the female drill bit 1 of setting, reaming bit 3, one end are provided with
The other end of external screw thread 2 is provided with the guided connector 4 of internal thread 5, and reaming bit 3 is connected with guided connector 4 by taper, bores
First 1 one end that guided connector 4 is provided with external screw thread 2 is connected, and guided connector 4 sets female one end and is provided with
Externally threaded drilling rod 6 is connected.
Before drilling, reaming bit 3 is connected with guided connector 4 by taper, then by drill bit 1 and guided connector 4
One end connection of external screw thread 2, guided connector 4 is provided with to be provided with one end of internal thread 5 and be connected with drilling rod.Due to using drill bit
1 is connected with the external screw thread 2 of guided connector 4 and instead of original starter so that combined drilling tool assembling is more flexible；Together
When in drilling, because drill bit 1 abrasion need to repair a die or change when, can quickly change so as to lift drilling efficiency, guided connector 4
Can repeatedly use；Simultaneously in the drilling that need not carry out reaming, drill bit 1 can directly be connected with drilling rod and use, and make
Work must be crept into flexibly to facilitate.
