이와 같은 본 고안 굴삭기용 면삭기 비트장착구조의 구체적인 구성과 작용을 첨부된 일 실시예로서의 도면을 참조하여 더욱 상세히 설명하면 다음과 같다.When described in more detail with reference to the accompanying drawings as a specific configuration and action of the present invention excavator surface mounting bit mounting structure for an excavator as follows.
도 2는 본 고안에 따른 굴삭기용 면삭기 비트장착구조의 구성을 보이는 사시도이고, 도 3은 본 고안에 따른 도 2의 분리사시도이고, 도 4는 본 고안에 따른 설치상태를 보이는 사시도로서 도 2내지 도 4에 의하면 본 고안의 굴삭기용 면삭기 비트장착구조는 비트(1)가 홀더(2)에 결합되는 형태로 되어 있다.Figure 2 is a perspective view showing the configuration of the excavator surface mounting device for an excavator according to the present invention, Figure 3 is an exploded perspective view of Figure 2 according to the present invention, Figure 4 is a perspective view showing an installation state according to the present invention Figure 2 According to Figure 4 to the excavator surface mounting structure for the excavator of the present invention is a form that the bit 1 is coupled to the holder (2).
즉, 중기의 붐(3) 선단에 구비된 회점드럼(4)에 다수의 상기 홀더(2)가 부착되어 있는데 이 홀더(2)는 일측 외주면이 상기 회전드럼(4)의 외주면과 같은 곡면을 이루어 회전드럼(4)의 외주면에 다수가 부착되어 있으며, 측방으로 관통되는 결합구멍(5)이 형성되어 있다.That is, a plurality of the holders 2 are attached to the point drum 4 provided at the tip of the boom 3 of the heavy machinery. The holder 2 has one outer circumferential surface of the same as the outer circumferential surface of the rotary drum 4. Many are attached to the outer peripheral surface of the rotating drum 4, and the coupling hole 5 penetrates laterally is formed.
상기 홀더(2)에는 상기 비트(1)가 결합되는데 이 비트(1)는, 자루부(6)가 형성되어 자루부(6)의 외주면에 외측방으로 탄성력을 가지는 링 형태의 키(7)가 결합되어 상기 홀더(2)의 결합구멍(5)에 자루부(6)가 결합되어서 홀더(2)에 비트(6)가 고정결합되어 있다.The bit 1 is coupled to the holder 2, which has a bag 6 formed therein and has a ring-shaped key 7 having an elastic force on an outer circumferential surface of the bag 6. Is coupled to the coupling portion 5 of the holder (2) is coupled to the bag portion (6) is a bit 6 is fixedly coupled to the holder (2).
이러한 구성에 의하면, 상기 회전드럼(4)이 회전을 하면서 회전드럼(4)의 외주면에 홀더(2)에 의해 장착되어 있는 비트(1)가 바닥면을 평활하게 다듬어 주게 된다.According to this configuration, the rotating drum 4 rotates to smooth the bottom surface of the bit 1 mounted on the outer circumferential surface of the rotating drum 4 by the holder 2.
이때, 회전드럼(4)의 회전시 비트(1)가 바닥면과 접하면서 비트(1)에 충격이 가해 지게 되고, 비트(1)에 충격이 가해지면서 비트(1)가 결합되어 있는 홀더(2)에도 충격이 가해지게 되는데 이는 상기 홀더(2)의 내부에서 비트(1)가 외측으로 탄성력을 가지는 키(7)에 의해 고정이 되어 있어서 비트(1)에 충격이 가해져도 비트(1)가 이탈이 되는 것이 방지가 되게 된다.At this time, when the rotating drum 4 is rotated, the bit 1 is in contact with the bottom surface and the shock is applied to the bit 1, and the shock is applied to the bit 1 while the holder is coupled to the bit 1 ( 2) an impact is also applied, which is fixed to the inside of the holder 2 by a key 7 having an elastic force outward so that the bit 1 may be impacted even if the bit 1 is impacted. It is prevented that the deviation occurs.
또한, 비트(1)에 충격이 가해져도 비트(1)가 홀더(2)로부터 이탈이 되는 것이 방지가 되게 되어 작업의 효율 및 비트(1)의 수명이 길어지게 된다.In addition, even when an impact is applied to the bit 1, the bit 1 is prevented from being separated from the holder 2, thereby increasing the efficiency of the work and the life of the bit 1.
상기 비트(1)의 교체에 따라 홀더(2)로부터 비트(1)의 분리시 홀더(2)에 형성되어 있는 결합구멍(5)에서 비트(1)를 분리시켜 주게 되는데 이때, 비트(1)가 결합되어 있는 홀더(1)의 반대편에서 별도의 도구를 사용하여 비트(1)의 자루부(6) 측면을 타격하게 되면 결합구멍(5)으로부터 비트(1)가 외부로 인출이 되게 된다.When the bit 1 is replaced according to the replacement of the bit 1, the bit 1 is separated from the coupling hole 5 formed in the holder 2. When hitting the side of the bag portion 6 of the bit (1) using a separate tool on the opposite side of the holder (1) to which the bit is coupled, the bit (1) is drawn out from the coupling hole (5).
도면상에 은선으로 도시한 부분은 상기 홀더(2)의 결합구멍(5)에 비트(1)의 결합시 비트(1)의 자루부(6)가 외부 즉, 결합된 반대편으로 돌출되는 것을 방지하기 위해 걸림턱(8)이 형성되어 있어서 작업시 비트(1)가 바닥면과 접하면서 발생되는 충격에 의해 비트(1)가 홀더(2)로부터 이탈되는 것이 방지가 되도록 된 것이다.The part shown by the hidden line in the figure prevents the bag portion 6 of the bit 1 from protruding to the outside, that is, the opposite side when the bit 1 is coupled to the engaging hole 5 of the holder 2. In order to prevent the bit 1 from being separated from the holder 2 due to the impact generated when the bit 1 is in contact with the bottom surface during operation, the locking step 8 is formed.
이상에서와 같은 본 고안 굴삭기용 면삭기 비트장착구조에 의하면, 회전드럼(4)에 비트(1)의 장착시나 교체시 홀더(2)로부터 비트(1)의 장착이나 분리가 원활하게 이루어지게 되고, 비트(1)의 사용되는 수명이 연장되게 되는 효과가 있는 고안인 것이다.According to the invented excavator surface mounting device for the excavator as described above, when the bit 1 is mounted or replaced on the rotating drum 4, the bit 1 from the holder 2 is smoothly mounted or removed. In other words, the invention is effective in that the service life of the bit 1 is extended.
