[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving seat support structure for an agricultural work vehicle in which a driving seat is mounted on a ceiling plate of a hood covering a driving part so as to be freely slidable along the longitudinal direction of the machine body.

[0002]

2. Description of the Related Art Conventionally, in a driving seat support structure for an agricultural work vehicle, as disclosed in, for example, Japanese Utility Model Application Laid-Open No. 56-124540, the driving seat is mounted on a ceiling plate of a horizontal hood via a slide support mechanism. The front and rear position change adjustment
Configured to support a standing, there is one provided the vertical position adjustable footrest device.

[0003]

In the above-mentioned conventional structure, the position of the driver's seat can be adjusted in accordance with the difference in the size of the driver. If the distance between the seat and the footrest is constant, the posture is not stable even when the position is adjusted to the front side, so that the footrest can be adjusted up and down. However, the conventional structure described above has a drawback in that a footrest device having a complicated link mechanism is required to support the driver's seat in a position-adjustable manner without deteriorating the steering operability. there were. The purpose of the present invention is to eliminate the above-mentioned disadvantages.

[0004]

According to a feature of the present invention, in the driving seat support structure for an agricultural work vehicle described at the beginning, the ceiling plate is provided in an upwardly inclined position, and the sliding support surface of the driving seat is moved rearward. If you set it to a rising and tilting posture
In addition, a muffler is attached to the rear position inside the hood.
Vertical position from near the ceiling to the bottom of the net
The point is that it is housed .

[0005]

According to the present invention, the support surface for supporting the driver's seat is provided in an oblique posture, so that the driver's seat slides,
Since the vertical position of the driver's seat changes upward as it moves backward, even if the footrest is set at a constant vertical position, it can be set to an appropriate position according to the difference in driver's physique Become. Moreover, the mechanism for adjusting and fixing the position of the driver's seat can simply be slid, and does not require a complicated link mechanism or the like. Further, since the ceiling plate of the hood is provided in a rearwardly inclined position, the rear space in the hood expands upward, and the rear space is increased .
Using the space effectively, there is a muffler 7 as shown in FIG.
From the ceiling to the bottom of the hood 10
The muffler 7 has a long path and large capacity
In addition, the outside air intake 20 of the air cleaner 9 can be set at a higher position than before, and the capacity of the reserve tank 8 can be increased.

[0006]

[Effect of the invention] Therefore, by improving the rational seat support structure, only a simple support mechanism can be repositioned to a position corresponding to the difference in the physique of the driver the driver's seat
I was like . In addition, the muffler has a large capacity
The air intake of the air cleaner can be
To a higher position than before, or
The capacity can be increased , and the size of tanks, engine cooling members, and the like in the prime mover can be increased.

[0007]

Embodiments will be described below with reference to the drawings. FIG.
1 shows a front part of a combine, which is an example of an agricultural work vehicle. In this combine, a cutting pre-processing device 1 is provided at the front of the fuselage, an operating unit 2 is disposed on the right side of the cutting pre-processing device 1, and a driving unit 3 is provided below the operating unit 2. It is composed.

The driving unit 3 has an engine 5 mounted on a body frame 4 and a radiator 6 for cooling the engine disposed laterally outward of the engine 5. A muffler 7 for silencing combustion exhaust gas is provided inside the hood 10. At the rear of engine 5
On the side, the bonnet 10 is disposed in a vertical posture extending from near the ceiling to near the bottom . A reserve tank 8 is provided at an upper rear portion of the engine 5, and an air cleaner 9 is mounted inside the lower body frame 4. The prime mover 3 is covered with a bonnet 10, and a driver's seat 11 is placed and supported on a ceiling plate 10 c of the bonnet 10. That is, as shown in FIG. 1, the rear portion 10a and the outer side portion 1 are provided so that the driver's seat 11 can be stably mounted and supported.
0b protrudes above the seat mounting support surface 15 to form a seat mounting space. And this bonnet 10
Is pivotally connected to the body frame 4 around the front-rear axis X1 at the lower end on the lateral outside side so as to be able to swing open for maintenance work of the engine 5 and the like in the driving unit 3.

On the front side of the driver's seat 11, a swing control lever 14 is provided above a control section post 13 erected from the driver step section 12. On the side, other operating levers are arranged to constitute the driving unit 2.

The ceiling plate 10c of the bonnet 10 is provided in an upwardly inclined position, and a seat mounting support surface 15 (an example of a slide support surface) of the bonnet 10 is formed in an upwardly inclined position. The driver's seat 11 is mounted and supported on the surface 15 by a slide support mechanism R so as to be slidable in the front-rear direction and freely fixed in position.
That is, as shown in FIGS. 3 and 4, a pair of left and right support rails 16 are mounted on the mounting support surface 15, and a guide member 17 which is slidably engaged with the support rail 16 is engaged with the driver's seat side. The driver's seat 11 to the mounting support surface 15
The locking member 18 is provided slidably along the mounting surface, and a plurality of locking recesses 18a of the locking member 18 provided on the mounting surface side are selectively engaged and disengaged with an engagement member 19 which is freely operable toward the seat in a biased state. The slide support mechanism R is configured by being attached.

By providing the seat mounting support surface 15 in the rearwardly inclined position as described above, the seat 1 according to the driver's physique can be obtained.
1 can be adjusted, and the upper surface of the bonnet 10 is formed in an oblique posture as described above.
The rear space inside the driving unit 3 expands upward, and the muffler 7 can be a large-capacity muffler having a long path. Further, as shown in FIG. 2, the outside air intake 20 of the air cleaner 9 can be set at a higher position than in the related art, and the capacity of the reserve tank 8 can be increased.

In the claims of the utility model registration, reference numerals are written to facilitate comparison with the drawings, but the present invention is not limited to the configuration of the attached drawings by the entry.
