[Operation] The working vehicle (10) of the present invention includes an operating lever (4) disposed near the side panel (35).
0, 42), the working machine (26)
A control computer (44) for controlling the vertical movement of the rear panel, and a predetermined panel formed between a rear panel (46) extending behind the side panel (35) and a protective cover (62) below the rear panel (46). By arranging the control computer (44) in the space, the space behind the side panel (35) is effectively used, and the distance between the control computer (44) and the side panel (35) is short. This simplifies the wiring route and facilitates the wiring work.

During maintenance and inspection, the rear panel (4
Since the control computer (44) can be easily taken out simply by attaching and detaching the protective cover (62) provided below 6), maintenance becomes easy.

The reference numerals in parentheses described above are for the purpose of comparing the drawings, and do not limit the present invention in any way.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. The same or corresponding members as in the conventional example are denoted by the same reference numerals.

FIGS. 1 and 2 are a partial plan view and a side view of a tractor 10 to which the present invention is applied. An upper part of a fender 21 covering the right rear wheel 18 of the tractor 10 has a work implement 26 mounted thereon. Setting volume 36 for adjusting the angle of
And a side panel 35 on which operating members such as an automatic tilt switch 38 that activates the automatic tilt device when switched on
Are formed. Further, a hydraulic position lever 40 and a working depth adjustment lever 42 for raising and lowering the work machine 26 by hydraulic pressure are disposed on the inner side closer to the seat 23 than the side panel 35.

In the present embodiment, a rear panel is extended integrally with the side panel 35 behind the side panel 35, and a protective cover is provided below the rear panel.
The control computer was placed in a predetermined space formed between the rear panel and the protective cover.

That is, in FIGS. 1 and 2, a rear panel 46 is extended behind the side panel 35, and the side panel 35 and the rear panel 46 are formed by molding means such as a mold. It is integrally molded of reinforced plastic material. A plurality of mounting seats 48a to 48c project downward from the rear surface of the side panel 35, and an iron plate cover 50 is mounted on the lower surface of each of the mounting seats 48a to 48c. Panel 3
A predetermined space is formed between 5 and the iron plate cover 50.

Short pedestals 48d and 48e are formed on the rear side of the rear panel 46 at the front and rear sides. Bolts 65a and nuts 6a are provided on the lower side of the front pedestal 48d.
5b, the front end side of a mud prevention cover (protective cover) 62 made of an iron plate and having a cross section bent in a crank shape is fixed. Further, a bolt 61 is provided on the lower surface side of the rear base 48e.
a and the nut 61b attach the bracket 60,
The rear end of the mud prevention cover 62 is fixed to the lower surface of the bracket 60 by bolts 63a and nuts 63b. The control computer 44 is disposed in a predetermined space formed between the mud prevention cover 62 and the rear panel 46.

On the side panel 35, predetermined mounting holes (not shown) are formed at positions corresponding to mounting of the tilt setting volume 36 and the tilt automatic switch 38, etc., and the tilt setting volume 36 is formed through these mounting holes. And automatic switch 3
8 is directly attached to the side panel 35 using the predetermined space. A wiring member 52 is connected to the terminals of the tilt setting volume 36 and the automatic tilt switch 38 by soldering or the like, and the wiring member 52 is drawn out to the control computer 44 or the like. At this time, the wiring member 52 can be laid along the upper surface of the iron plate cover 50, so that the iron plate cover 50 serves as a wiring guide for the wiring member 52.

As shown in FIG. 3, the wiring member 52 is
The control computer 44 connects the tilt setting volume 36 and the tilt automatic switch 38 to the control computer 44, and is pulled out from the control computer 44 to a switch 53 for recognizing the up / down operation of the lift arm 28. For convenience, the inner surface of the rear wheel 18 and the switch 5
A mudguard plate 64 is interposed between the third and the like. And
The mudguard plate 64 prevents the mud scattered from the rear wheel 18 from adhering to the switch 53 and the like, and the mudguard plate 64 is used as a wiring guide when the wiring member 52 is laid. Since the wiring route is determined to some extent by the anti-sludge plate 64, the wiring route is standardized. Note that a connector 45 for buzzer check, a connector 47 for storing a microcomputer, and the like are attached to various wiring members drawn out from the control computer 44 (see FIG. 2).

As shown in FIG. 2, the side panel 35 has an inclined surface 35a whose front portion is inclined upward, and a substantially horizontal surface 35b whose rear portion is substantially horizontal. Automatic tilt switch 3 with built-in ramp
8 are disposed, and the inclination setting volume 3 is provided on the horizontal surface 35b.
6 are arranged. A flasher lamp 54 is mounted on the fender 21 at an intermediate position in the front-rear direction connecting the side panel 35 and the rear panel 46 with a bolt 57a and a nut 57b to notify left and right turning of the machine body.

As shown in FIGS. 4 and 5, a rubber cap 56 is attached to the lower rear surface of the flasher lamp 54 to cover a connecting portion 54a of the flasher lamp 54 with the wiring member 55. This cap 56
A rib 58 is attached to the outer peripheral portion of the cap so as to prevent the cap 56 from being turned up by falling muddy soil, vibration, or the like and falling off.

In this embodiment, the case where the side panel 35 is formed on the upper part of the fender 21 which covers the periphery of the right rear wheel 18 has been described. However, the present invention is not limited to this. A side panel 35 may be formed on the upper part of the covering fender 21.

Next, the operation will be described.

According to the present embodiment, the rear panel 46 is formed by extending the side panel 35 formed above the right rear wheel 18 rearward, and the mud prevention cover 62 is provided below the rear panel 46. Since the control computer 44 is disposed in a predetermined space formed between the rear panel 46 and the mud prevention cover 62, the space behind the side panel 35 can be effectively used. The distance between the control computer 44 and the side panel 35 is reduced and the wiring route is simplified as compared with the case where the control computer 44 is arranged below the seat 23.
Thereby, for example, the wiring route between the control computer 44 and the side panel 35 is connected by a substantially straight line, so that the wiring work is facilitated and the appearance of the wiring portion is improved. A protective cover 62 is provided below the rear panel 46.
Provided, the protection cover 62 can be easily attached and detached, and the maintenance of the control computer 44 can be improved.

[0023]

As described above, according to the first aspect of the present invention, the rear panel extends behind the side panel,
By providing a protective cover below the rear panel and arranging the control computer in a predetermined space formed between the rear panel and the protective cover, the space behind the side panel can be effectively used. At the same time, since the distance between the control computer and the side panel is shortened, the wiring route is simplified, the wiring work is easy, and the appearance of the wiring structure is improved.

Further, since the protective cover is provided below the rear panel, the control computer can be taken out simply by attaching and detaching the protective cover, so that the maintenance can be improved.
