Abstract
Spiral sectional rod, comprises drilling rod body, the external Zhou Buyou spiral channel of drilling rod, it is characterized in that: described spiral channel is divided into spiral channel a and spiral channel b, spiral channel a and spiral channel b is equidistant placement; The two ends of described drilling rod body are evenly equipped with outer silk; The inside of described drilling rod body is provided with water hole; The periphery of described spiral channel a and spiral channel b is evenly distributed with and thickeies projection; Described water hole divide centered by the interstitial hole of water hole and the centrally center line circumference array in water hole.The usefulness of this utility model is, this utility model is the chip removal of double helix road, chip removal is effective, extend the application life of drilling rod, the head and the tail two ends of drilling rod are equipped with outer silk simultaneously, and joint can be utilized as required to carry out dismounting, improve operating efficiency, convenience is rapid, good airproof performance, verticality are good, and rate of penetration is fast, and drilling via formations is good.
Description
Technical field
The utility model relates to engineering drilling, mine locating drilling tool accessory field, coal seam, is specifically related to a kind of spiral sectional rod.
Background technology
In mine locating drilling tool, drilling rod is absolutely necessary one of apparatus, and when carrying out mine coal seam, can the work that can drilling rod normal, safe be one of the key that normally carry out of drilling project.Drilling rod condition of work is depending on coal seam quality, conventional drill needs to change at any time according to coal seam quality in use, affects operating efficiency, and drilling rod operationally needs to discharge flying chip in time simultaneously, chip removal freely can not cause drill rod breaking, affects its application life and operating efficiency.
Summary of the invention
The utility model, for above problem, provides a kind of spiral sectional rod.
The utility model is achieved through the following technical solutions: spiral sectional rod, comprise drilling rod body, the external Zhou Buyou spiral channel of drilling rod, described spiral channel is divided into spiral channel a and spiral channel b, spiral channel a and spiral channel b is equidistant placement, it is characterized in that: the two ends of described drilling rod body are evenly equipped with outer silk; The inside of described drilling rod body is provided with water hole; The periphery of described spiral channel a and spiral channel b is evenly distributed with and thickeies projection; Described water hole divide centered by the interstitial hole of water hole and the centrally center line circumference array in water hole.
The usefulness of this utility model is, this utility model is the chip removal of double helix road, chip removal is effective, extend the application life of drilling rod, the head and the tail two ends of drilling rod are equipped with outer silk simultaneously, and joint can be utilized as required to carry out dismounting, improve operating efficiency, convenience is rapid, good airproof performance, verticality are good, and rate of penetration is fast, and drilling via formations is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1 drilling rod body, 2 spiral channel a, 3 spiral channel b, 4 outer silks, 5 water holes, center, 6 interstitial holes.
Detailed description of the invention
Spiral sectional rod, comprises drilling rod body 1, and drilling rod body 1 periphery is furnished with spiral channel, and described spiral channel is divided into spiral channel a2 and spiral channel b3, and spiral channel a2 and spiral channel b3 is equidistant placement, it is characterized in that: the two ends of described drilling rod body 1 are evenly equipped with outer silk 4; The inside of described drilling rod body 1 is provided with water hole; The periphery of described spiral channel a2 and spiral channel b3 is evenly distributed with and thickeies projection; Described water hole divide centered by the interstitial hole 6 of water hole 5 and the centrally center line circumference array in water hole 5.
The utility model is equipped with outer silk 4 at the head and the tail two ends of drilling rod body 1, can need to utilize joint indefinite extension according to boring, meet the needs of different operating environment, improve operating efficiency, the utility model adopts double helix road chip removal mode simultaneously, and when High Rotation Speed, chip removal is more clean, is provided with thickeies projection in the outside of spiral channel a2 and spiral channel b3, on the basis not affecting its chip removal and duty, enhance abrasion resistance and the application life of spiral channel.
