Kind Code:

Abstract:
To provide a drain discharge mechanism of a work machine which can easily discharge a drain, and does not become an obstacle at non-use.SOLUTION: A drain discharge part 40 arranged at a frame sidewall of a soundproof box is formed into a telescopic structure which is composed of a cylindrical inner cylinder 41 and a cylindrical outer cylinder 42 which is externally fit to the inner cylinder 41, and the outer cylinder 42 is constituted so as to be advanceable and retractable between a withdrawal position in which a tip 423 of the drain discharge part is extended, and an accommodation position in which the tip 423 of the drain discharge part is pushed into a machine with respect to the withdrawal position. Also, a stopper mechanism for sealing a clearance between an external periphery of the inner cylinder 41 and an internal periphery of the outer cylinder 42 by using an O-ring, and regulating the withdrawal of the outer cylinder 42 exceeding the withdrawal position is arranged. By this constitution, at a drain discharge, the outer cylinder 42 is withdrawn, and the drain discharge part 40 is extended up to an upper part of a collection vessel, and after a finish of the drain discharge, the outer cylinder 42 is pushed in and accommodated, thus preventing contact with a worker or the like.SELECTED DRAWING: Figure 3
