drifter of rock driller for reducing noise
An object of the present invention is to provide a low-noise rock drill which can prevent noise generated from a drifter and a shank unit from being amplified by being transmitted to a main body unit forming a sound insulation space. The low-noise rock drill according to the present invention comprises: the main body unit which has a sound insulation space inside, and a support coupling unit coupled to a boom of an excavator at one end; at least one drifter which is supported by forward and backward transfer units in the sound insulation space of the main body unit, moves forwards and backwards inside the sound insulation space and is installed such that the shank unit is inserted and withdrawn into the sound insulation space of the main body unit; and a vacuum generating unit installed in the main body unit to make the inside of the sound insulation space vacuum, and to cool the drifter by blowing in outside air.
본 발명에 따른 저소음 착암기는 내부에 차음공간을 가지며 일측 단부에 굴삭기의 붐과 결합되는 지지결합부를 가지는 본체부와, 상기 본체부의 차음공간에 전,후 이송유닛에 지지되어 상기 차음공간의 내부에서 전, 후진되며 샹크부가 상기 본체부의 차음공간로 인입 및 인출되도록 설치되는 적어도 하나의 드리프트와, 상기 본체부에 설치되어 상기 차음공간의 내부를 진공시킴과 아울러 외기를 취입하여 드리프터을 냉각시키기 위한 진공발생유닛을 구비한다.
