Problems solved by technology

However, such an increase in the number and size of the air intake port deteriorates the appearance of the excavator, and also promotes the leakage of noise such as engine noise to the outside and the intrusion of rainwater.
Also, the reduction in the effective area of ​​the shield makes it difficult to attach design stickers, reminder labels, etc.
As additional waterproofing measures for the intake port, there are methods of installing shutters on the intake port and strengthening waterproofing of electronic components, but these measures lead to a significant increase in cost

Abstract

Provided is a construction machine including a guard panel with an air suction port and capable of ensuring a required intake opening area with suppressed disadvantages of the air suction port. The construction machine includes an engine, a cooling fan, and a heat exchanger which are accommodated in a device accommodation space in an upper slewing body, and a guard panel covering the device accommodation space. The guard panel includes a first panel with an opening edge defining an opening and a second panel that opens and closes the opening and has a peripheral portion to be supported by the opening edge with the opening closed. Respective parts of the peripheral portion and the opening edge are shifted from each other in an inward-outward direction to form an air suction port bringing the device accommodation space into communication with outside, between the second panel and the first panel.

Description

technical field [0001] The present invention relates to a construction machine, and more particularly to a construction machine having a heat exchanger and an air intake structure for introducing cooling air from the outside to the heat exchanger. Background technique [0002] by Figure 4 to Figure 6 An excavator is shown as an example to illustrate the background of the invention. [0003] The excavator has Figure 4 , 5 The shown crawler-type undercarriage body 1, an upper revolving body 2 mounted on the undercarriage freely rotatable around an axis O perpendicular to the ground, and an excavation work mounted on the front part of the upper revolving body 2. front attachment 3. In this specification, "front and rear" and "left and right" represent directions viewed from the inside of the cab 4 provided in the upper revolving structure 2 . [0004] The excavator is also Image 6 As shown in , a rear guard 5 , a counterweight 11 , and a side guard 12 are further provid...
