Problems solved by technology
[0004] When lifting the dust filter upward as described above, the operator climbs on the upper surface of the engine hood, opens the opening and closing cover on the upper surface side, and lifts the dust filter upward. It is difficult to shorten the work time from taking out to inserting after cleaning
In addition, the fixing part for fixing the dust filter is located on the upper side, and the operator cannot disassemble the dust filter without removing the part required to take out or put the dust filter in the engine hood when he / she climbs on the platform or the upper surface of the engine hood. It takes time to attach and detach the dust filter

Embodiment approach 1
[0066] figure 1 It is a perspective view seen from the back side of a construction machine to which an embodiment of the dustproof net attachment structure of the present invention is applied. Such as figure 1 As shown, in this embodiment, as a construction machine, a small rotary type small hydraulic shovel 10 will be described as an example. This small-swing type hydraulic shovel 10 is set such that the amount of protrusion of the engine room 14 on the rear side of the cab 12 is small.
[0067] The small hydraulic excavator 10 is generally composed of a self-propelled crawler-type undercarriage 20 and a revolving upper body 30 rotatably mounted on the undercarriage 20 . In addition, a cab 12 and a work attachment 40 are provided on the front side of the upper revolving structure 30 .
[0068] The work attachment 40 has a boom 42, an arm, a bucket, and the like. In addition, the illustration of the arm and the bucket is omitted. The boom 42 is attached to a rotating fram...

The invention discloses a dustproof net installation structure of construction machinery capable of carrying out the taking out / inserting in operation of the dustproof net simply in a short time. The dustproof net installation structure (120) is provided with a pair of guide rails (130,132) fixedly disposed on a frame (74) of a heat radiator (72), and a fixing mechanism (140) used for fixing a right side edge part (106) of the fixing dustproof net (100). The dustproof net (100) can be guided by the guide rails (130,132) to be taken out from the rear part (X1direction) of the rear part of the suction side opening (16), and then can be cleaned. A first carrying rack (150) can be extended from the upper part of the frame (74) of the heat radiator (72) by bridging over the dustproof net installation structure (120). A second carrying rack (152) can be bridging over the dustproof net installation structure (120)under the frame (74) of the heat radiator (72) to be extended upwards. And when the dustproof net moves along the guide rails, the dustproof net cannot be contacted with the first and the second carrying racks.
Description
technical field [0001] The invention relates to a dustproof net installation structure of a construction machine. Background technique [0002] In a conventional construction machine, an upper revolving body is mounted above a crawler-type undercarriage so as to be rotatable in the horizontal direction. A cab, an arm supporting the bucket, and a boom supporting the arm are arranged on the front side of the upper revolving body, and an engine room is provided on the rear side of the upper revolving body (for example, refer to Patent Document 1). In addition, in small construction machines including ultra-small rotary hydraulic shovels and rear ultra-small rotary hydraulic shovels, it is desirable that the maximum rotational radius of the upper rotary body protrude as little as possible to the outside of the lower traveling body. Therefore, the engine room has a compact structure and is equipped with various equipment such as the engine, radiator, condenser, oil cooler, and i...
