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

Embodiment Construction

[0019] refer to Figure 1 to Figure 3 Embodiments of the present invention will be described. In this embodiment, the present invention is applied to an excavator. The excavator according to the present embodiment is compatible with the following points (A) to (C) Figure 4 to Figure 6 Same excavator as shown. Therefore, for the structure involved in the same point, for example, the lower walking body, the front attachment, etc., a part of the equipment, the machine, the description of the background art and the Figure 4 to Figure 6 , the detailed description is omitted.

[0020] (A) The excavator according to this embodiment includes a crawler-type undercarriage, an upper revolving body 2 mounted on the undercarriage freely around an axis O perpendicular to the ground, and an upper revolving body 2 mounted on the upper revolving body. A front attachment for excavation work at the front of the body 2.

[0021] (B) A rear guard is provided at the rear of the upper slewing b...

Abstract

The invention provides construction machinery. This construction machine includes an engine housed in an equipment storage space of an upper revolving body, a cooling fan, a heat exchanger, and a shroud covering the equipment storage space. The shroud has a first cover that surrounds an opening edge of the opening, and a second cover that opens and closes the opening and has a peripheral edge supported by the opening edge of the first cover when the opening is closed. A part of the peripheral portion of the second cover and a part of the corresponding opening edge of the first cover are displaced from each other in the inner-outer direction, and a suction hole that communicates with the equipment storage space and the outside is formed between the second cover and the first cover. breath. Accordingly, it is possible to suppress the problems caused by the conventional air intake port and ensure a necessary air intake opening area.

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...
