Embodiment Construction

[0072] Next, embodiments of the present invention will be described with reference to the drawings.

[0073] figure 1 A construction machine showing one embodiment of the present invention. In this embodiment, a hydraulic shovel 1 will be described as an example of a construction machine.

[0074] The hydraulic excavator 1 includes a crawler-type undercarriage 2 capable of self-propelling, a revolving upper body 3 mounted on the undercarriage 2 so as to be able to turn, and the like. In addition, an operation attachment 4 is provided on the front side of the upper revolving body 3 .

[0075] The operation attachment 4 has a boom 6, an arm 9, a bucket 10, and the like. The boom 6 is mounted on the revolving frame 5 so as to be capable of pitching and moving. The arm 9 is rotatably attached to the front end side of the boom 6 . In addition, the bucket 10 is rotatably attached to the front end side of the arm 9 .

[0076] The boom cylinder 12 is arranged between the revolvi...

Abstract

The invention provides a construction machinery capable of realizing high efficiency of the installation operation of the dustproof net. The construction machinery is provided with a heat exchange device (24) comprising heat exchangers (24A-24E) disposed on a frame (25). The cooling wind (39) is used to cool the refrigerant flowing in the heat exchangers (24A-24E). A dustproof device (40) is provided with a pair of carrying racks (41A,41B), which are separated by the heat exchange device (24), and are disposed on the frame (25); and dustproof nets (51,52), which are detachably disposed on the carrying racks (41A,41B). The dustproof device (40) is provided with guiding members (46A,46B,47A,47B), and are used for the guiding of the dustproof nets (51,52)along the installation direction and along the direction orthogonal to the installation direction.

Description

technical field [0001] The invention relates to a construction machine with a dustproof net. Background technique [0002] Generally, a construction machine such as a hydraulic excavator has a heat exchange device for cooling an engine. The heat exchange device is cooled by cooling air generated by a cooling fan driven by the engine. In addition, a dust-proof device with a dust-proof net is provided on the suction side of the cooling air of the heat exchange device to prevent the cooling fins provided in the heat exchange device from being blocked by dust and the like. [0003] This dust filter requires maintenance because dust will adhere to it. Therefore, the dustproof net is configured to be detachable from the dustproof device. Conventionally, in order to install the dustproof net to the dustproof device, a claw is provided at the lower part of the dustproof device where the dustproof net is installed, and the lower end of the dustproof net is inserted into the claw t...
