The utility model discloses connect the brill tooth of drill bit part as an organic whole, two liang of through -holes that bore between the tooth have a perfect understanding the row of formation thick liquid hole each other, and brill tooth integrative on the one hand can stop partial row of sediment, upwards discharges from the drilling rod, and it is great that the row of having a perfect understanding on the one hand starches the hole, avoids cinder shutoff drilling rod, improves the slip casting ability, promotes work efficiency.
Description
Technical field
This utility model relates to a kind of preventing and extinguishing fire of coal mine drill bit and drilling rod, specifically a kind of preventing and extinguishing fire of coal mine grouting drilling tool.
Background technology
Goaf coal spontaneous combustion is one of disaster affecting mine safety production, underground coal mine working face extraction and withdraw period, easily causes coal spontaneous combustion disaster.Common fire extinguishing mode has grouting, note three-phase froth, inert gas injection, gel-filled material etc., detailed description of the invention is to utilize to goaf pipe laying, with adopting with note fireproofing extinguishing materials, owing to many fireproofing extinguishing materials are with water for source material, and pipe laying overlay area, goaf is limited, therefore during the above-mentioned fireproofing extinguishing materials of practical application, large area cannot cover goaf, centering high position burning things which may cause a fire disaster point (region) cannot form effectively preventing, therefore, from practice, utilizing directed replacement pipe laying of drilling between frame is the technological means gone out now to the goaf water base fireproofing extinguishing materials of perfusion.
In prior art, grouting drill bit is generally 3 wings or 4 wing drill bits, namely bit part I 3 or 4 bore teeth, then bore again and tooth offered the hole for pulp, owing to slurry outlet is arranged on brill tooth, hole is less, and during drilling work, cinder is upwards arranged, it is easy to closure drilling rod so that serosity is difficult to discharge.
Summary of the invention
For above-mentioned prior art Problems existing, this utility model provides a kind of preventing and extinguishing fire of coal mine grouting drilling tool, it is to avoid cinder closure drilling rod, improves the stability of deslagging, promotes work efficiency.
To achieve these goals, this utility model one preventing and extinguishing fire of coal mine grouting drilling tool, including drill bit；Described drill bit includes connecting rod end, and is fixed on the multiple wing drill bit connected on rod end；The brill tooth front end of described multiple wing drill bit connects as one, and bores between two and forms through hole between tooth, and each through hole is mutually communicated and forms the plasma discharge hole being connected with drilling rod.
This utility model is further, is provided with female thread inside described connection rod end.
This utility model is further, and described multiple wing drill bit is 3 wing drill bits.
This utility model is further, also includes drilling rod, and described drilling rod one end is provided with and is connected the female adapter that rod end coordinates, and the other end is provided with the female thread for connecting rig.
This utility model is further, and described drilling rod periphery is provided with the external screw thread for deslagging.Along with the increase of drilling depth, cinder carries out outer row by the external screw thread on drilling rod, improves the stability of deslagging, avoids cinder closure drilling rod further.
Compared with prior art, the brill tooth of bit part is connected as one by this utility model, the through hole bored between tooth is mutually communicated formation plasma discharge hole between two, on the one hand the brill tooth of one can stop portions deslagging, upwards discharging from drilling rod, plasma discharge hole through on the one hand is bigger, it is to avoid cinder closure drilling rod, improve slip casting ability, promote work efficiency.

Detailed description of the invention
In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, this utility model preventing and extinguishing fire of coal mine grouting drilling tool, including drill bit；Described drill bit includes connecting rod end 3, and is fixed on the multiple wing drill bit 1 connected on rod end；The brill tooth front end of described multiple wing drill bit 1 connects as one, and bores between two and forms through hole between tooth, and each through hole is mutually communicated and forms the plasma discharge hole 2 being connected with drilling rod.Wherein multiple wing drill bit 1 can be 3 wings, 4 wings etc., and it is 3 wing drill bits that this utility model provides a kind of scheme.
On said structure basis, this utility model connects rod end 3 inside and is additionally provided with female thread 4, in order to connect with drilling rod.As it is shown on figure 3, this utility model also includes drilling rod, described drilling rod one end is provided with and is connected the female adapter 5 that rod end 3 coordinates, and the other end is provided with the female thread 4 for connecting rig.
Additionally, as it is shown on figure 3, drilling rod periphery is provided with the external screw thread 6 for deslagging.Along with the increase of drilling depth, cinder carries out outer row by the external screw thread 6 on drilling rod, improves the stability of deslagging, avoids cinder closure drilling rod further.
Drill between period frame withdrawing, as shown in Figure 4, supporting rig 8 is fixed on hydraulic support 7, connects edema due to wind pathogen pipeline, drilling rod and drill bit are installed, adjust blowing angle and height according to design, start motor and carry out wet type and drill.
Certainly, above-described embodiment is only preferred version of the present utility model, is specifically not limited thereto, and can make pointed adjustment on this basis according to actual needs, thus obtaining different embodiments.Owing to mode in the cards is more, just no longer illustrate one by one here.
