A muffler draining apparatus for a working machine is provided which allows a drain line having excellent heat resistance to be reliably installed, even when a device or equipment is present at the position below a muffler. In a muffler draining apparatus that is provided to a muffler (12) equipped to a hydraulic excavator, and includes a drain line that discharges water accumulated in the muffler to the outside of a vehicle body, the above-described drain line includes a single metal tubing (23) whose one end (23a) is connected to the muffler, and whose intermediate portion (23c) provided continuous to the one end (23a) is extended into the space formed between the muffler and a hydraulic pump (11) located below the muffler. The intermediate portion (23c) of the metal tubing (23) includes a single linear portion (23c1) and plural bent portions (23c2). Also, the muffler draining apparatus includes, for example, a single support bracket (20) that is fixed to the muffler, and supports the intermediate portion of the metal tubing.
Description
technical field [0001] The present invention relates to a muffler drainage device for a machine tool having a drain pipe for discharging water accumulated in a muffler of the machine tool to the outside of the vehicle body. Background technique [0002] As such prior art, there is a technique disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 4-24623). This prior art is a technique in which one discharge hose constituting a drain pipe for discharging water accumulated in the muffler to the outside of the vehicle body is connected to the muffler. The discharge hose is generally composed of a rubber hose. In other words, the prior art disclosed in Patent Document 1 is configured such that the upper end of one rubber hose is connected to the lower portion of the muffler, and the entire rubber hose is hung down, so that The water at the bottom is introduced into the rubber hose and flows down from the lower end of the rubber hose to the outside of the ve...
