Abstract

Disclosed is a construction machine in which a muffler for reducing the noise of exhaust gas emitted from the engine is mounted inside a counterweight. According to the present invention, the construction machine on which a counterweight having a muffler is mounted comprises: an upper frame pivotably mounted on a lower moving body; a driver compartment and an engine compartment mounted on the upper frame; a suction pipe communicating with the exhaust pipe of an engine mounted in the engine compartment, and into which exhaust gas flows; a muffler main body for reducing the noise of inflowing exhaust gas by means of a noise reducing device therein; a muffler comprising an exhaust pipe which emits the muffled exhaust gas to the outside; a working tool pivotably mounted on the front end of the upper frame and consisting of a boom, an arm, and a bucket which are respectively driven by a hydraulic cylinder; and a counterweight mounted on the rear end of the upper frame and having a compartment formed so as to mount the muffler therein.

Description

Technical field [0001] The invention relates to a construction machine equipped with a counterweight device with a muffler. More specifically, the present invention relates to a construction machine installed with a counterweight device having a muffler, in which a muffler for reducing noise of high-temperature and high-pressure exhaust gas discharged from an engine is installed inside the counterweight device. Background technique [0002] Such as figure 1 As shown, the excavator using the existing technology includes: [0003] Lower driving structure 1; [0004] The upper frame 2, which is pivotally mounted on the lower traveling structure 1; [0005] Cab 3 and engine room 4, which are installed on the upper frame 2; [0006] An additional device 11, which is rotatably installed at the front end of the upper frame 2, and includes a boom 6, an arm 8 and a bucket 10 driven by hydraulic cylinders 5, 7 and 9 respectively; and [0007] The counterweight 12a is installed at the rear end of...
