이하, 본 발명의 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

도 1 내지 도 3을 참조하면, 본 발명에 따른 암반 굴착용 툴은 로드(10)의 선단에 나선부(14)가 형성되고, 로드(10)와 나선부(14)의 경계면에 경사부(12)가 테이퍼 지게 형성되고, 헤더비트(20)에 나선체결홈(24)이 형성되고, 나선체결홈(24)의 테두리에 안착부(22)가 테이퍼 지게 형성되어, 헤더비트(20)가 로드(10)의 나선부(14)에 나사결합되면, 헤더비트(20)의 안착부(22)와 로드(10)의 경사부(12)가 맞닿아진다. 1 to 3, in the rock drilling tool according to the present invention, the spiral portion 14 is formed at the tip of the rod 10, and the inclined portion is formed on the interface between the rod 10 and the spiral portion 14. 12 is formed to be tapered, the spiral fastening groove 24 is formed in the header bit 20, the seating portion 22 is formed to be tapered on the edge of the spiral fastening groove 24, the header bit 20 is When screwed into the spiral portion 14 of the rod 10, the seating portion 22 of the header bit 20 and the inclined portion 12 of the rod 10 abuts.

상기 로드(10)의 일단에 충격부(16)가 형성되고, 로드(10)의 외측면 일단에 고정홈(17)이 형성된다. An impact portion 16 is formed at one end of the rod 10, and a fixing groove 17 is formed at one end of the outer surface of the rod 10.

상기 헤더비트(20)는 원뿔 형상으로 외측면에 돌기(25)와 나선형의 플루트(27)가 형성된다. The header bit 20 has a conical shape is formed with a projection 25 and a spiral flute 27 on the outer surface.

이것에 의해, 브레이커에 본 발명에 따른 암반 굴착용 툴이 장착되어, 지반을 천공하는 과정에서, 강도가 높은 암반이 나타난다. Thereby, the rock drilling tool according to the present invention is attached to the breaker, and the rock with high strength appears in the process of drilling the ground.

이때, 로드(10)와 헤더비트(20)가 나사결합되어 있기 때문에, 브레이커에서 로드(10)를 교체하지 않고, 로드(10)의 나선부(14)의 규격에 맞는 다른 강도의 헤더비트(20)만을 빠르고 간편하게 교체할 수 있다. At this time, since the rod 10 and the header bit 20 are screwed together, a header bit of different strength that meets the standard of the spiral portion 14 of the rod 10 without replacing the rod 10 in the breaker ( 20) Only quick and easy replacement is possible.

또한, 로드(10)와 헤더비트(20)가 독립적으로 존재하여, 로드(10)와 비트(20)의 강도를 다르게 구성할 수 있다.In addition, since the rod 10 and the header bit 20 are independently present, the strengths of the rod 10 and the bit 20 can be configured differently.
