Abstract
A kind of air-driven impact formula geological drilling rig suitable for rockfill area drilling, it is characterized by it and includes geological drilling rig, connector, stent-type hidden hole drilling impactor, connector is hollow pipe, one end is threaded the shaft in hole and stent-type hidden hole drilling impactor top, the other end is threaded the shaft in hole and geological drilling rig drilling rod lower part, and geological drilling rig connects with high-pressure air hose.The utility model becomes air-driven impact formula geological drilling rig by the way that geology drilling improvment, geological drilling rig and stent-type hidden hole drilling impactor are attached by designed joint, weight ratio stent-type down-the-hole drill weight, and when drilling is more firm；Power is more sufficient after transformation, improves drilling working efficiency, and bit freezing is met during promotion when failures, and processing drilling accident is easy.
Description
Technical field
The utility model is related to the connectors that stent-type hidden hole drilling impactor and geology bore drilling rod.
Background technology
When at present, for easy collapse hole earth-boring, eccentric drilling machine is purchased, of high cost, rate of penetration is slow, and purposes is single, partially
Heart drilling machine is suitable only for the easily collapse hole Special Geological Condition such as sand gravel, enrockment.It is bored using XY-2PC geology, also commonly referred to as fetched water
It bores, is rotation by drill bit slowly, wherein water is mainly used for the heat that drill bit is generated with rock frictional test that cools down, for rockfill area
Drilling, if drilled using the drilling machine, water easily washes away and takes away the finger stone or soil of surrounding, during trip-out drilling hold
It easily caves in, cement mortar is also diluted during retaining wall, more difficult retaining wall.And stent is bored, it can be with when rockfill area drills
, but retaining wall is just dying, and main cause drilling rod cannot be up and down, and slurries cannot good retaining wall.
Invention content
The purpose of this utility model is to provide a kind of power abundances, and can improve drilling working efficiency is suitable for rockfill area
The air-driven impact formula geological drilling rig of drilling.
Technical solution is a kind of air-driven impact formula geological drilling rig suitable for rockfill area drilling used by the utility model,
It is characterized by it and includes geological drilling rig, connector, stent-type hidden hole drilling impactor, and connector is hollow pipe, and one end is machined with spiral shell
Pit and the shaft on stent-type hidden hole drilling impactor top, the other end are threaded hole and geological drilling rig drilling rod lower part
Shaft, geological drilling rig connects with high-pressure air hose.
Geological drilling rig is improved and becomes air-driven impact formula by the utility model, and improved air-driven impact formula geological drilling rig is excellent
Point has：Weight ratio stent-type down-the-hole drill weight, when drilling, are more firm；Power is more sufficient after transformation, improves drilling working efficiency, is promoted
When meet bit freezing when failures, processing drilling accident is easy.
Two opposite card slots are machined in the middle part of the outer surface of connector.The tools such as wrench easy to use carry out screwing connection.
Be machined with two opposite the Ith card slots in the middle part of the outer surface of connector, be machined on different height with the Ith card slot into
90 degree of the IIth card slot.It is firm into 90 degree of card slot progress by two pairs, while strength of joint is ensured
The utility model by geology drilling improvment, designed joint by geological drilling rig and stent-type hidden hole drilling impactor into
Row connection, becomes air-driven impact formula geological drilling rig, weight ratio stent-type down-the-hole drill weight, and when drilling is more firm；Power after transformation
It is more sufficient, drilling working efficiency is improved, bit freezing is met during promotion when failures, processing drilling accident is easy.
Description of the drawings
Fig. 1 is the usage state diagram of the utility model
Fig. 2 is the structure diagram of connector
Wherein：The Ith card slot 82 of 1 enrockment, 5 bedrock surface, 6 cement mortar or 7 geological drilling rig of mud, 71 high-pressure air hose, 8 connector 81
II card slot, 9 stent-type hidden hole drilling impactor, 10 air compressor machine.
Specific embodiment
The utility model is described in detail with reference to view, cited embodiment can make the skill of this profession
Art personnel more understand the utility model, but do not limit the utility model in any form.
As shown in Figure 1, 2, a kind of air-driven impact formula geological drilling rig suitable for rockfill area drilling, it includes geological drilling rig 7
（Such as XY-2PC geological drilling rigs）, connector 8, stent-type hidden hole drilling impactor 9, connector be hollow pipe, one end is threaded hole
With the shaft on stent-type hidden hole drilling impactor top, the other end is threaded the spiral shell in hole and geological drilling rig drilling rod lower part
Rasp bar coordinates, and the water inlet pipe that geology is bored is changed to high-pressure air hose, and geological drilling rig connects with high-pressure air hose 71, high-pressure air hose during use
Connect with air compressor machine 10.General ventilation bore 25-33mm, wind flow general control is in 1.5m3/min-3m3/min, 12m3/
The air compressor machine of 0.8MPA can simultaneously 3 improved drilling machines of band, when drilling be mainly used for the power air quantity too great Yi of impactor
Hole wall is caused to destroy, air quantity is too small, and diffusion effect is poor.
Two opposite card slots are machined in the middle part of the outer surface of connector.It is machined in the middle part of the outer surface of general connector opposite
Two the Ith card slots 81 are machined with the Ith card slot on different height into 90 degree of the IIth card slot 82.
The utility model is suitable for drilling on the enrockment 1 of bedrock surface 5, cement mortar or mud 6 while drilling
Carry out Gu Bi.
