Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement structure of an air cleaner in a work vehicle such as a tractor.

[0002]

2. Description of the Related Art Conventionally, an air cleaner of a work vehicle such as a tractor is provided in an engine room. For example, air is taken in from a front side of the engine room through a front grill, and the engine side has an air cleaner. Air is supplied to On the other hand, it is desirable to send relatively low-temperature air to the engine, which requires a heat shield structure in the air cleaner.However, if the air cleaner is in the engine room, the heat shield structure becomes complicated and Disadvantageously consumes more space than necessary.

[0003]

In order to solve the above-mentioned problems, an arrangement of an air cleaner in a work vehicle according to the present invention is provided with an engine 11 in a bonnet 6 in front of a driver's seat 7, and in an intake system of the engine 11. In a working vehicle provided with an air cleaner 17 and an operation meter panel 12 in front of the driver's seat 7, the air cleaner 17 is disposed inside a panel support 16 that supports the meter panel 12, and the engine room 9 and the panel support are provided. A heat shield member 23 for preventing heat generated on the engine 11 side from invading into the panel support 16 is provided between the panel support 16 and the front side of the section 16.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of a tractor which is a working vehicle to which the present invention is applied. A traveling body 1 is supported by front and rear wheels 2 and 3, and an engine room surrounded by a side cover 4 and a hood 6 is provided in front of the traveling body 1, and a seat 7 is provided behind the engine room. Driver seats 8 are provided, respectively. An engine 11 is disposed in an engine room 9 as shown in FIG. 2. An operator sits in a driver's seat 8 in a driver's seat 8 and operates the engine 11 to operate the tractor, as is conventionally known. (Driving of a working machine and the like).

On the other hand, FIG. 2 is a side perspective view of the front side of the driver's seat 8, and a meter panel 12 for operating a tractor is disposed in front of the driver's seat 8 located behind the hood 6 so as to be covered by a panel cover 13. The steering handle 14 protrudes from below the meter panel 12. As in the related art, the operator can visually check or operate instruments and switches on the meter panel 12 and operate the steering handle 14.

The meter panel 12 (panel cover 13) is supported by a panel frame 16 which is a panel support for supporting the meter panel 12. At this time, the panel frame 16 is integrally attached to the body frame 1a, is framed, and stands up, and a predetermined space S is formed inside the panel frame 16 (within the panel frame 16 frame). ing. An air cleaner 17 is attached to the space S, and the air cleaner 17 and the engine 11 are connected via a suction hose 18.

An air filter 19 made of punched metal or the like is mounted on the left side surface of the panel frame 16. An end of an intake hose 21 of the air cleaner 17 is mounted on the air filter 19. That is, the air cleaner 17 is configured to suck air through the air filter 19 on the side of the meter panel 16 (the left side surface of the panel frame 16) and supply the air to the engine 11 through the suction hose 18. .

A lid 10 for maintenance of the air cleaner 17 is attached to the panel frame 16 above the air filter 19 so as to be openable and closable so as to face the air cleaner 17. Can be easily maintained.

On the other hand, a hood rear frame 22 is provided behind the engine room 9, and a panel frame 16 is arranged behind the hood rear frame 22. A plate-like heat shielding member (heat shielding plate) 23 is attached to the front side of the hood rear frame 22.
The heat generated in the engine room 9 (the engine 11 side) is prevented from entering the panel frame 16.

As a result, the air cleaner 17 is disposed inside the panel frame 16 which is shielded from the engine room 9, so that the air cleaner 17 is less affected by the hot air on the engine 11 side (temperature rise, etc.) and the engine 1
The temperature of the intake air does not become unnecessarily high and the adverse effect on the operation of the engine 11 is small.

In particular, an air filter 19 is arranged on the side of the driver's seat 7 (the left side of the panel frame 16), and the intake to the air cleaner 17 is performed from the side of the driver's seat 7. There is no adverse effect of a cooling fan or the like provided in front.

As a result, the suction of dust or the like due to negative pressure or the like is reduced, and the dust or the like is prevented from adhering to the air filter 17, the radiator, the front grille, and the like.
Air can be supplied stably to the engine 11
Can be prevented from being overheated. In addition, since the rotation of the cooling fan can be reduced, noise can also be reduced.

The air cleaner 17 is provided in the engine room 9.
The space inside the engine room 9 and the panel frame 16 can be used effectively, and the space can be saved. In addition, the heat shielding structure for the air cleaner 17 is not provided between the engine room 9 and the panel frame 16. Is realized by disposing a heat shield plate 23 between
The heat shield structure is relatively simple.

When the maintenance of the air cleaner 17 is performed, it is not necessary to open the hood 6, and the maintenance of the air cleaner 17 can be easily performed by opening the lid 10.

On the other hand, as shown in FIG. 3, the cabin 25 is mounted on the tractor in this embodiment, and the rear wheel 3
A pole 27 indicating the center of the rear wheel may be attached to the upper rear part of the fender (rear fender) 26. Thus, for example, as shown in FIG. 4, when the tractor is loaded on a truck bed 28 or the like using the road slope 29,
In the vehicle (in the driver's seat 7), the position of the road slope 29 and the rear wheel 3 can be easily adjusted without the operator taking an unnatural posture.

At this time, as shown in FIG. 5, the pole 27 may be rotatably mounted so that the pole 27 can be stored in a falling position. In this case, the pole 27 can be tilted and stored when unnecessary. Further, as shown in FIG. 6, the pole 27 may be configured to be extendable and contractible. In this case, the pole 27 can be stored by contracting the pole 27.
By extending the pole 27, the pole 27 can be made relatively high.

As a result, as shown in FIG. 7, it is easy to check the pole 27 even when the working machine 31 is mounted on the traveling body 1 of the tractor. Bed 28
For example, when the tractor is loaded using the road slope 29, the positioning of the road slope 29 and the rear wheel 3 can be easily performed, and the loading on the truck becomes easy.

Further, as shown in FIG. 8, a substantially L-shaped stay 32 is attached to the rear end surface 26b of the rear fender 26 so as to be able to turn (swing) left and right, and a pole 27 is attached to the rear end of the stay 32. It may be a mounted structure. In this case, the left and right positions of the pole 27 can be adjusted by swinging the stay 32 as shown in FIG. 9. For example, when the tread of the rear wheel 3 is changed, the swing of the stay 32 causes the pole 27 to swing. The left and right positions can be easily adjusted to the center of the rear wheel, and the position of the pole 27 can be easily adjusted.

[0019]

According to the structure of the present invention configured as described above, the air cleaner is not disposed in the engine room, so that the space in the engine room and the panel support portion can be effectively used, and the engine side can be used. A heat-shielding structure for the heat generated by the air cleaner can be realized by disposing a heat-shielding member between the engine room and the panel supporting portion, which has an advantage that the heat-shielding structure can be simplified. .
