Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body structure of a working machine such as an excavating work machine.

[0002]

2. Description of the Related Art A conventional body structure of a working machine includes a turning machine having an engine and auxiliary equipment such as a battery attached to the engine. The turning machine has a seat portion for the driver and a driver's seat. Some are equipped with a heating system. The heating device is used particularly in winter, and there are a heating device provided below the seat portion and a heating device by sending hot air from the engine to the driver's seat portion side.

[0003]

By the way, the working machine described above is required to be miniaturized so as to be able to cope with various working states. For the miniaturization, the location of the heating device becomes a problem. . When the heating device is arranged below the seat as described above, the heating device emits heat. Therefore, an auxiliary device such as a battery which is likely to be adversely affected by heat should be arranged around the heating device. Therefore, a separate space for arranging them is required, which hinders miniaturization.When heating is performed by sending hot air from the engine to the driver side, a space for arranging a special heating device is provided. Is suitable for downsizing, but the hot air from the engine may contain dust and dirt, and blowing this hot air on the driver will cause dust and the like on the seat and the driver. It gave an unpleasant feeling such as adhesion and stain.

Therefore, according to the present invention, in order to solve the above-mentioned problems, both the heating device and the auxiliary equipment can be arranged below the seat portion, whereby the space can be effectively utilized and the working machine An object of the present invention is to provide a body structure of a working machine that can be downsized.

[0005]

According to the present invention, there is provided on a traveling device 5 a swivel body 4 having a drive device 18 and an auxiliary device 20 associated with driving, and a seat portion for a driver is provided on the swivel body 4. In order to achieve the above-mentioned object, the following technical measures are taken in the structure of the working machine including the heating device 21 for the driver.

That is, below the seat portion 9, the auxiliary device 2
0 and the heating device 20 are arranged, and a shielding plate 14 for partitioning the heating device 21 and the auxiliary equipment 20 is provided. The heating device 21 is detachably fixed to the shield plate 14.

The shield plate 14 is detachably provided below the seat portion 9.

[0008]

The heating device 21 for the driver and the auxiliary device 20 such as a battery are arranged below the seat portion 9 provided on the swivel body 4, and the shielding plate 14 is provided between the two devices 20 and 21. The heat from the heating device 21 is blocked by the shield plate 14 and hot air is prevented from flowing to the auxiliary device 20, so that adverse effects due to the heat are prevented. Therefore, the seat portion 9
Since both the heating device 21 and the auxiliary device 20 can be arranged below the device, there is no need to separately secure a place to arrange the auxiliary device 20 or the heating device 21, and the working machine can be downsized.
