Problems solved by technology

In addition, in order to replace the filter arranged on the path of the pipe, various parts must be removed, and the replacement of the filter is troublesome
That is, workability when assembling the air conditioner is deteriorated
In addition, there is also a problem that workability during maintenance such as filter replacement is also reduced.

Embodiment Construction

[0054] Embodiments of the present invention will be described below with reference to the drawings.

[0055] Figure 8 It is a side view of a hydraulic shovel that is a construction machine according to an embodiment of the present invention. exist Figure 8 In the hydraulic excavator 10 , the upper revolving body 13 is placed on the lower traveling body 11 via the revolving mechanism 12 so as to be able to rotate freely. A cab (operation cab) 14 and an equipment room 18 are provided above a frame cover 13 a of the upper revolving body 13 . A boom 15 is attached to a front central portion of the upper slewing body 13 so as to be rotatable up and down by a boom cylinder 15 a. At the front end of the boom 15, an arm 16 is attached so as to be rotatable up and down by an arm cylinder 16a. At the front end of the arm 16, a bucket 17 is mounted rotatably by a bucket cylinder 17a.

[0056] In the equipment room 18 of the upper revolving structure 13, a battery, a hydraulic pump...

Abstract

A construction machinery cab (14) is provided with an intake port (34) that opens underneath the floor of the construction machinery cab (14) and sucks in outside air. A filter (39) that filters outside air is housed in a filter housing unit. A lid member (33) for closing the opening of the filter housing unit is rotatably mounted to the side of the cab. An outside air introduction section (38), one end of which is connected to the intake port (34) and the other end of which is connected to the filter (39), is formed between a panel on the inside of the cab (37) and a panel on the outside of the cab (36). An intake route passes from the intake port (34) through the outside air introduction section (38), and through the filter (39) to an air-conditioning unit (41) of an air-conditioner. The lid member (33) can be opened when doing maintenance work on the filter (39), and prevents the filter (39) from being soaked with water when the opening of the filter housing unit is closed.

Description

technical field [0001] The present invention relates to construction machines such as hydraulic shovels and hydraulic cranes, and more particularly to a construction machine operator's cab (cab) provided with an air conditioner inside. Background technique [0002] Generally, a hydraulic shovel as a construction machine includes an undercarriage, an upper revolving body rotatably mounted on the undercarriage, and working equipment such as an excavator movably installed on the upper revolving body. A cab constituting an operator's cab is provided on the frame of the upper revolving body. [0003] A cab used in a conventional construction machine includes a cab box having an upper surface, a front surface, a rear surface, and left and right side surfaces. A door for opening and closing a landing through which an operator boards and disembarks is provided on one of the left and right side parts of the cab box. An air conditioner is provided in the cab box. The air conditione...
