본 고안은 지표면을 굴삭하는 굴삭기의 회전축에 연결되어 사용되는 굴삭공구에 관한 것으로서, 특히 굴삭공구가 구성요소별로 분리 제조되어 일체로 체결된 굴삭공구에 관한 것이다.The present invention relates to an excavation tool used in connection with an axis of rotation of an excavator for excavating the ground surface, and more particularly relates to an excavating tool is integrally fastened separately manufactured by the component.

일반적으로 지표면을 굴삭하는 굴삭공구는 양단에 나선홈이 형성된 철재봉의 하반부에 스크류의 굴삭날이 끼워져 용접되고 그 하단의 나선홈에 제2의 굴삭날이 형성된 굴삭구가 나합 체결되어 굴삭공구의 상단이 굴삭기의 회전축에 연결되도록 구성되어 있다.In general, an excavation tool for digging the ground surface is welded by inserting an excavation blade of a screw into a lower half of an iron rod having spiral grooves at both ends thereof, and an excavation hole having a second excavation blade formed into a spiral groove at the bottom thereof to be screwed together to form an upper end of the excavation tool. It is comprised so that it may be connected to the rotating shaft of this excavator.

그러나 상기한 종래의 굴삭공구는 굴삭날이 형성된 센터고정용 안내날이 굴삭공구의 하단에 굴삭공구와 일체로 형성되어 있어 상기의 센터고정용 안내날이 훼손되는 경우 굴삭공구 일체를 교체하여야 하는 문제점이 있었을 뿐만 아니라 굴삭공구의 철재봉에 용접된 스크류 형상의 굴삭날도 단단한 지표면 때문에 쉽게 마모되어 굴삭공구의 수명이 단축되는 문제점이 있었다.However, the above-described conventional excavating tool has a center fixed guide blade having an excavating blade formed integrally with the excavating tool at the lower end of the excavating tool, and thus, when the center fixing guide blade is damaged, the digging tool must be replaced. In addition, there was a problem that the screw-shaped excavation blade welded to the steel rods of the excavating tool was also easily worn because of the hard surface, which shortened the life of the excavating tool.

따라서, 본 고안은 상기의 문제점을 해결하기 위하여 안출된 것으로, 스크류 굴삭날을 보강하여 마모를 줄임으로써 수명을 연장함과 아울러 센터고정용 안내날이 형성된 부위만을 교체가능토록 하여 교체비용을 줄일 수 있는 굴삭공구를 제공하는데 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and by reducing the wear by reinforcing the screw excavator blades to extend the life and to replace only the portion where the center fixed guide blades are formed to reduce the replacement cost The purpose is to provide an excavation tool.

상기의 목적을 실현하기 위한 본 고안은 센터고정용 안내날과 굴삭날이 형성된 제1굴삭구와 봉의 외주면에 스크류 굴삭날이 끼워져 용착되고 스크류 굴삭날의 하단부에 초경합금의 굴삭편이 형성된 제2굴삭구로 구성된 굴삭공구에 있어서 상기 제1굴삭구의 일단에 나선부가 돌출되어 형성되고 상기 봉의 끝단에 나선홈이 형성되어 상기 제1굴삭구의 나선부가 상기 봉의 나선홈에 끼워져 나사결합되고, 상기 스크류 굴삭날의 표면에 지표층을 분쇄하여 스크류 굴삭날의 마모를 방지하는 복수개의 파쇄편이 일정간격을 두고 용착된 것을 특징으로 한다.The present invention for realizing the above object is composed of a first guide hole for the center fixed guide and the excavation blade and a second excavation hole is formed by welding the screw excavation blade to the outer circumferential surface of the rod and the excavation piece of cemented carbide at the lower end of the screw excavation blade In an excavation tool, a spiral portion is formed to protrude at one end of the first excavation tool, and a spiral groove is formed at an end of the rod so that the spiral portion of the first excavation tool is screwed into the spiral groove of the rod and screwed to the surface of the screw excavator blade. The crushed surface layer is characterized in that a plurality of crushed pieces are welded at a predetermined interval to prevent wear of the screw excavator blade.

이하, 첨부된 도면을 참조하여 본 고안의 실시예를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

본 고안은 제1굴삭구(1)와, 제2굴삭구(2)와 연결봉(3)과 제1체결구(4)와, 제1체결구(5)로 구성된다.The present invention consists of a first excavation hole (1), a second excavation hole (2), a connecting rod (3), a first fastener (4), and a first fastener (5).

제1굴삭구(1)는 끝단부에 센터고정용 안내날(11)과 중앙부에 굴삭날(12)이 형성되고 그 일단에 나선부(13)가 돌출되게 구성된다. 제2굴삭구(2)는 일단에 나선홈(24)과 타측단에 나선(25)이 형성된 봉(21)과 상기 봉에 스크류 굴삭날(22)이 끼워져 용착되고 상기의 스크류 굴삭날 중 하단부에 위치한 굴삭날의 표면에는 초경합금의 굴삭편(23)이 하측을 향하여 돌출되도록 용착되어 있다.The first excavation hole 1 is configured such that the center fixed guide blade 11 and the excavation blade 12 are formed at the end thereof, and the spiral portion 13 protrudes at one end thereof. The second excavation hole 2 is a rod 21 having a spiral groove 24 at one end and a spiral 25 formed at the other end thereof, and a screw excavator blade 22 is fitted and welded to the rod, and a lower end portion of the screw excavator blade is welded. Excavation piece 23 of cemented carbide is welded to the surface of the excavating blade located in the projecting downward.

한편, 스크류 굴삭날(22)의 표면에는 굴삭되는 지료층을 파쇄시켜 스크류 굴삭날(22)의 훼손 및 마모가 방지될 수 있도록 파쇄편(26)이 일정한 간격을 두고 용착되어 있다.On the other hand, the shredding piece 26 is welded on the surface of the screw excavation blade 22 at regular intervals so as to break the material layer to be excavated to prevent damage and wear of the screw excavation blade 22.

상기의 제2굴삭구(2)와 굴삭기의 회전축(미도시) 사이에 위치되는 연결봉(3)의 양단에는 나선부(31, 32)가 형성된다. 제1체결구(4) 및 제2체결구(5)는 내부에 나선홈이 형성되어 있다.Spiral portions 31 and 32 are formed at both ends of the connecting rod 3 positioned between the second excavator 2 and the rotary shaft (not shown) of the excavator. The first fastener 4 and the second fastener 5 have spiral grooves formed therein.

제1굴삭구의 나선부(13)는 나선홈(24)에 결착되고 봉(21) 및 연결봉(3)의 일단에 각각 형성된 나선부(25, 31)는 제1체결구(4)에 나삽되어 연결되며 연결봉(3)의 타단에 형성된 나선부(32)는 제2체결구(5)에 나삽된다. 상기의 굴삭공구는 굴삭기의 회전축(미도시)에 제2체결구(5)를 통하여 결합된다.The spiral portion 13 of the first excavation hole is fastened to the spiral groove 24, and the spiral portions 25 and 31 formed at one end of the rod 21 and the connecting rod 3 are respectively screwed into the first fastener 4 The spiral portion 32 connected to and formed at the other end of the connecting rod 3 is screwed into the second fastener 5. The excavator tool is coupled to the rotating shaft (not shown) of the excavator through the second fastener (5).

상기의 제1체결구(4)의 중앙부위에는 작은홈(41)이 형성되어 상기의 홈(41)에 긴 강성부재(미도시)를 삽입하여 상기 제1체결구를 용이하게 회전시킬 수 있게 한다.A small groove 41 is formed in the central portion of the first fastener 4 so that a long rigid member (not shown) can be inserted into the groove 41 to easily rotate the first fastener. .

상기와 같이 구성된 본 고안은 굴삭공구가 회전되어 지표면을 굴삭할때 스크류 굴삭날(22)에 용착되어 돌출된 파쇄편(26)이 회전되면서 흙이나 돌을 분쇄하게 되어 스크류 굴삭날(22)의 마모가 적게되므로 굴삭공구의 수명을 연장시킬 수 있다.The present invention configured as described above is the excavation tool is rotated to excavate the ground surface is welded to the screw excavation blade 22 to protrude the crushed piece 26 is rotated to crush the soil or stone of the screw excavation blade 22 Less wear can extend the life of excavator tools.

또한, 센터고정용 안내날(11)과 굴삭날(12)이 형성된 제1굴삭구(1)가 마모되거나 훼손된 경우에는 굴삭공구 전체를 교체할 필요없이 제1굴삭구(1)를 제2굴삭구(2)로부터 해체시켜 제1굴삭구(1)만을 교체하면 되므로 교체 비용이 절감되는 효과가 있다.In addition, when the first fixing tool 1 having the center fixing guide blade 11 and the cutting tool 12 is worn or damaged, the first excavator 1 is second excavated without having to replace the entire excavation tool. Dismantling from the sphere (2) only need to replace only the first excavator (1) has the effect of reducing the replacement cost.
