본 고안은 스크류로 돌려서 구멍을 뚫는 지하 천공기에 있어서, 스크류하단에 다운햄머(Down hammer)를 장착하고 다운햄머의 외주면에 스크류날개를 형성하여 종래 스크류식 천공기와 햄머식 천공기의 단점을 해결한 천공기에 관한 것이다.The present invention is a drill that solves the shortcomings of the conventional screw-type drill and hammer-type drill by installing a down hammer at the bottom of the screw and forming a screw blade on the outer circumferential surface of the down hammer in the underground drill that drills holes by turning with a screw. It is about.

종래의 건축 시공을 위하여 땅에 구멍을 뚫는 천공기는 그 방식에 있어 그 크기를 제외하고는 2종으로 구분할 수 있는데 그중 하나는 나사식으로 돌려서 구멍을 뚫는 스크류식 천공기가 있고 압축공기에 의하여 햄머를 작동시켜서 구멍을 뚫는 햄머식 천공기가 있다.Conventional drills for drilling holes in the ground can be divided into two types except for their size. One of them is a screw-type drill drilled by screwing a hole. There is a hammer-type perforator that operates to drill holes.

전자의 나사식 천공기는 돌이 없는 지층에서는 효과적으로 구멍을 뚫을 수 있는 장점이 있는 반면, 돌이 있는 지층에서는 불가능한 단점이 있는 것이고, 후자의 햄머식 천공기는 돌이 있는 지층 같은 곳에서는 좋지만 쉽게 함몰되는 전석층, 자갈층에서는 공기압도 저하되고 슬라임(slime)의 토출이 어려운 결점이 있는 것이다.The former screw perforator has the advantage of being able to drill holes effectively in the rockless strata, while the disadvantage is impossible in the strata with stones, while the latter hammer drill is good but easy to sink in places like the strata with stones, In the gravel layer, the air pressure is also lowered and slime is difficult to discharge.

이외에도 배토용 공압의 증대등에 따른 공비가 과다하게 요구되는 등의 여러가지 단점이 있다.In addition, there are various disadvantages, such as excessively required public affairs due to the increase of the pneumatic pressure for laying.

본 고안은 위와같은 종래의 제반 단점을 해결할 수 있게 하기 위하여 스크류식 천공기에 햄머를 장착하고 햄머의 외주면에도 스크류날개을 형성하여서 슬라이임의 배토를 스크류에 의하여 수행토록 하므로서 지층형편에 구애없이 천공작업을 용이하게 할 뿐만 아니라 천공비용도 대폭 절감할 수 있게 한 것이다.In order to solve the above-mentioned drawbacks of the present invention, the hammer is mounted on a screw-type perforator and a screw wing is formed on the outer circumferential surface of the hammer so that the topsoil of the slime is carried out by the screw, thereby making it easy to drill the boring work regardless of the geological formations. In addition to this, the drilling cost can be greatly reduced.

이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

차체(1)의 전방에 종설된 안내대(2)상에 스크류축(3)과 이를 회전하는 회전기(4)를 설치한 공지의 구성에 있어서 스크류축(3)의 하단에 나사공(3a)을 형성하여 다운햄머(5)의 상단에 돌출된 나사봉(5a)을 끼우고 햄머(5)의 외주면에 스크류날개(6)를 형성한 것이다.In a well-known configuration in which a screw shaft 3 and a rotator 4 rotating the same are provided on a guide 2 arranged in front of the vehicle body 1, a screw hole 3a is provided at the lower end of the screw shaft 3. To form a screw rod (5a) protruding on the top of the downhammer (5) to form a screw blade (6) on the outer circumferential surface of the hammer (5).

미 설명부호7은 에어콤푸레셔이고 8은 발전기를 표시한 것이다.Reference numeral 7 denotes an air compressor and 8 denotes a generator.

이와같이 구성된 본 고안은 다운햄머(5)를 작동하면서 구멍을 뚫고 이때 생겨난 슬라임은 스크류날개(6)및 스크류축(3)에 의하여 배토하게 되므로서 구멍을 깊이 파고들어가도 배토에 염려가 일체 없으며 지질에 구애없이 모두 천공할 수 있는데 장점이 있는 것이고 압축공기는 햄머 작동용으로만 사용되는 것이므로 종래와 같이 공기로 배토시키는 것에 비하여 콤푸레셔의 소형화에 따라 비용이 대폭 절감되는데도 장점이 있으며 또 지질변동에 따라 장비 교체사용의 불편이 없는데도 효과가 있는 것이다.The present invention configured as described above drills a hole while operating the downhammer (5), and the slime generated at this time is dissipated by the screw blade (6) and the screw shaft (3), so even if the hole is deeply drilled, there is no concern about the soil. All of them can be drilled without any special purpose. Compressed air is used only for hammer operation. Therefore, compared with the conventional method of discharging with air, the cost is greatly reduced due to the compactness of the compressor. It is effective even though there is no inconvenience in replacing equipment.

이상과 같이 본 고안은 스크류식 천공기에 햄머를 장착한 것과 햄머의 외주면에 스크류날개를 형성한 구성에 특징이 있다.As described above, the present invention is characterized in that the hammer is mounted on the screw-type perforator and that the screw blade is formed on the outer circumferential surface of the hammer.
