The utility model discloses guarantee plastic hose's implantation when creeping into, when extracting the drilling rod at last, plastic hose plays the effect of reinforcing drilling in staying drilling like this, prevents that the phenomenon of shutoff or deformation from appearing in drilling.
Description
Technical field
The utility model relates to drilling technique field, is specifically related to a kind of big orifice auger stem.
Background technology
All need to use in engineering geological drilling and mineral reserve drilling process, auger stem extensive use in coal production process, in order to prevent coal and non-coal burst accident and water leak accident, before driving, need again in coal seam, to beat release aperture the gas in coal seam is discharged with this to eliminate stress of coal seam, or verified no water layer by boring.At present, there is the little shortcoming of bore in old-fashioned drilling rod, and old-fashioned drilling rod often causes borehole sealing or distortion at the end of boring, makes follow-up work be difficult to carry out, causes very large impact and loss.Therefore, a kind of new technical scheme must be provided to solve.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of big orifice auger stem, this big orifice drilling rod ensures the implantation of plastic flexible pipe while creeping into, when so in the end extracting drilling rod, plastic flexible pipe stays in boring the effect played and reinforce boring, and preventing from holing occurs the phenomenon of shutoff or distortion.
Technical problem to be solved in the utility model realizes by the following technical solutions:
Big orifice auger stem, it comprises drilling rod body, it is characterized in that: implanting on described drilling rod body has plastic flexible pipe, described drilling rod cup two ends are installed with tool joint, the described drilling rod cup outer wall be positioned in the middle of two tool joints is provided with helical blade, described helical blade is for equidistantly and the hand of spiral is consistent is arranged on drilling rod body outer wall, and the setting of described helical blade is the other end being extended to drilling rod cup from drilling rod body one end, is also processed with friction welding seam at the two ends of described drilling rod body.
As optimal technical scheme, described helical blade is the one in single thread blade, twin-feed spiral blade, three helical blades, and group number the best of described helical blade is three groups, and the lead angle of described helical blade is 60 degree of settings.
As optimal technical scheme, be also provided with threaded portion at the two ends of described drilling rod body, and the axiality of described threaded portion and drilling rod body periphery is to be not more than 0.6mm for standard.
As optimal technical scheme, the external surface of described drilling rod cup is shiny surface vibrational power flow, and to visually observe smooth impulse-free robustness without obvious open defect welding defect for standard.
As optimal technical scheme, external diameter and the even deviation of wall unevenness of described drilling rod body ensure within the scope of positive and negative 0.5mm, and with the defect such as flawless and obvious corrosion for standard.
Further, the lead angle of described helical blade can need according to operating mode the welding carrying out not angle.
The beneficial effects of the utility model are:
1) easy to use, simple to operate, automaticity is high, and safety factor is high;
2) the utility model can ensure the implantation of plastic flexible pipe while creeping into, when so in the end extracting drilling rod, plastic flexible pipe stays in boring the effect played and reinforce boring, and preventing from holing occurs the phenomenon of shutoff or distortion, causes Effects on Engineering and economic loss; Lead angle can need to carry out angle welding according to operating mode, and reach best effect, screw thread blade is set to three groups more can effectively discharge mud and rock.
