Next, a specific embodiment of the filter mounting structure of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a side view of a filter mounting structure for an engine according to the present invention. This filter mounting structure is used, for example, in a construction machine A as shown in FIG. In addition,
The construction machine A shows a hydraulic shovel in FIG.

That is, the construction machine A in this case, which is a hydraulic shovel, includes a lower traveling body 1 and an upper revolving body 2 pivotally connected to the lower traveling body 1. Further, the upper revolving unit 2 includes a revolving frame 3, and a cab 4, an engine room 5, a counterweight 6 (attached to the attachment portion 6 a), and the like are provided on the revolving frame 3.
Working machines such as a boom 7, an arm 8, a bucket 9, and the like are connected to each other from the front of the work.

As shown in FIG. 1, an engine 10 is housed in the engine room 5, and an openable and closable lid member 12 is attached to an exterior cover 11 thereof. That is, the exterior cover 11 has a protruding portion 13 protruding upward, and a substantially rectangular opening 16 is provided in a part of the peripheral wall 14 to the upper wall 15 of the protruding portion 13. The lid member 12 has, for example, an L-shaped cross section, and the edge of the short piece 17 is pivotally attached to the upper wall 15 of the protruding portion 13. As shown in FIG. 1, when the long piece 18 of the lid member 12 is swung upward, the opening 16
Is opened, and from this state, the long piece 18
Is pivoted downward to dispose the long piece 18 on the same plane as the peripheral wall 14 of the protruding portion 13, whereby the opening 16 is closed. In addition, a handle member 19 is attached to the long piece 18 of the lid member 12.

The filter 20 of the engine 10 is located above the engine 10, that is, the outer cover 11.
Is attached to the upper wall 15. By the way, the engine 10
The filters 22 required for the above are an oil filter, a fuel filter, a water filter (corrosion register), and the like. In this embodiment, the oil filter is attached to the outer cover 11. That is, the filter 20 includes a casing 21 and an element (not shown) housed inside the casing 21, and the upper wall 1 of the outer cover 11.
The upper part of the casing 21 is fixed via the fixing means 22 provided in the 5. The fixing means 22 includes, for example, a connecting body connected to the upper wall 15 by bolts and nuts, and the fixing portion of the casing 21 is connected to this connecting body.

As described above, in this embodiment, the filter 20 is arranged near the opening 16.
That is, as shown in FIG. 3, the filter 20 is arranged at a higher position than the conventional one shown in FIG. Therefore, the filter 20 and the engine 10
Outgoing pipe 23 having a longer length than conventional ones
And a return pipe 24. In addition, going pipe 2
Flexible piping is used for 3 and the return piping 24. In this case, the engine 10 is provided with an installation base (not shown) and is fixed to the installation base.

On the side of the engine 10, a maintenance floor 26 which is higher than the bottom plate 25 of the engine room 5 is provided. That is, the maintenance floor 26 is formed so as to extend in the horizontal direction from near the lower edge of the opening 16, and the worker S on the maintenance floor 26 can open and close the lid member 12. .

According to the filter mounting structure, since the filter 20 is provided near the opening 16, when maintenance work of the filter 20 becomes necessary, as shown in FIG.
When the lid member 12 is opened, the operator S on the maintenance floor 26 can easily reach the filter 20 through the opening 16. Thereby, the worker S is lying on his stomach, and there is no need to perform the maintenance work of the filter 20 in a state where his head is stuck in the engine room 5. That is, from the standing position of the worker S on the maintenance floor 26, the filter 20 can be reached in a standing state, a bent state, or a kneeling state. Filter maintenance work becomes possible. Therefore, the maintainability is improved as compared with the conventional filter mounting structure, and the working time can be reduced. In addition, there is also an advantage that it is safe for the worker S because the head does not need to be inserted into the engine room 5.

Although a specific embodiment of the filter mounting structure of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications are made within the scope of the present invention. It is possible. For example, the maintenance floor 26 in a state in which the worker S does not enter the engine room.
The filter 20 disposed at a position where the filter maintenance work can be performed may be a fuel filter, a water filter (corrosion register), or the like. In this case, all the filters may be arranged at such positions, only one of them may be arranged, or two of them may be arranged.
Particularly preferred is an oil filter as in the embodiment. This is because the oil filter is heavier than the other filters, and it is difficult to work at the lower position. Also, there is a risk that a danger may arise when the fuel filter is disposed at an upper position, and maintenance work is not performed very frequently with a water filter. The location (fixed) of the filter 20 and the position of the opening 16 of the exterior cover 11 are not limited to the exterior cover 11. Any position may be used as long as the filter maintenance work from the maintenance floor 26 can be performed. Furthermore, this filter mounting structure can be used for various construction machines such as bulldozers other than the hydraulic excavator.
