    • The present invention relates to a low noise hydraulic breaker including: a cylinder (110) having a piston (111) movable in upward and downward directions at the inside thereof if gas is supplied from a valve (113) to a gas chamber (112) located at the upper portion thereof, while pressure pulsation is being removed at an accumulator (114); a breaking part (120) having a chisel (121) located at the lower portion of the cylinder (110) for breaking a given broken-to-be object; a striking part (130) having a striking chamber in which the piston (111) of the cylinder (110) strikes the chisel (121) of the breaking part (120) and fixedly supported by means of upper and lower bushes (132) and (134) with respect to the chisel (121) and by means of a key (133) coupling the upper and lower bushes (132) and (134); a noise-absorbing part (140) for absorbing the striking noise generated at the inside of the striking chamber (131) of the striking part (130); and an exhausted air absorbing part (150) for secondarily absorbing the exhausted air at a state where the noise is primarily removed at the noise-absorbing part (140).
    • 本发明涉及一种低噪音液压断路器,包括:一气缸,其具有一活塞,其活塞可在其内部向上下方向移动,如果气体从阀门113提供给气室, 位于其上部,同时在蓄压器(114)处移除压力脉动; 具有位于所述气缸(110)的下部的凿子(121)的断裂部分(120),用于破坏给定的被破坏物体; 具有撞击室的撞击部分(130),其中气缸(110)的活塞(111)撞击破裂部分(120)的凿子(121)并且通过上下衬套(132)和 (134)相对于凿子(121)并通过联接上下衬套(132)和(134)的键(133)而形成。 用于吸收在撞击部分(130)的击打室(131)内部产生的撞击噪声的吸声部分(140); 以及用于在噪声吸收部分(140)处主要去除噪声的状态下二次吸收排出的空气的排气吸收部分(150)。

    • A rock crusher is provided to perform rock crushing work easily by coupling simply to a boom of an excavator and inserting to a perforated hole of a bedrock layer and widening/splitting the bedrock layer with uniform hydraulic pressure. A rock crusher(100) attached to a boom of an excavator is disclosed and inserted to a perforated hole of a bedrock layer to supply strong hydraulic force evenly over the whole surface of the bedrock layer in the perforated hole and to widen the bedrock layer to be cracked and crushed by attaching an upper corporate body(10) to a boom(202) of an excavator(200), inserting a cracking structure fitted with an opening structure to a perforated hole of a bedrock layer, operating a hydraulic cylinder(16) attached on the base of the upper corporate body and projecting a piston of the hydraulic cylinder in the downward direction and pressurizing the top of a primary opening end(34) united to the top of a reciprocating bar(32) of the opening structure, moving the primary opening end along an incline formed on the top of primary and secondary outer bushings(20,22) in the downward direction using the pressure of the piston to widen the upper part of the primary and secondary outer bushings in the outer direction and moving a secondary opening end(36) of the reciprocating bar along the surface of each hanging projection(26) in the downward direction to widen the middle and lower part of the primary and secondary outer bushings in the outer direction, so that the whole surface of the primary and secondary outer bushings gives pressure to the whole surface of the bedrock layer in the perforated hole evenly.
