Description

[Detailed description of the invention] The present invention relates to the structure of the driving section of a tractor, and the elbow rest and the mounting panel for the switches of the ground work equipment, which are arranged on the side of the driver's seat, are easy to manufacture and assemble. In addition to remodeling it, we aim to provide switches with excellent operability.

The tractor driving section structure of the present invention is such that the elbow rest placed on the side of the driver's seat is attached to the rear wheel fender, and switches are installed to control the elevation of the ground work equipment. The panel is integrally configured with the elbow rest, and the switch mounting panel is positioned on the lateral side of the driver's seat with respect to the elbow rest, and the operation surface of the switch mounting panel is integrally constructed. It is oriented toward the driver's seat side, and this configuration provides the following effects.

In other words, since the elbow rest and the switch mounting panel are integrated, installation on the aircraft is easy, and
Since the switch mounting panel is located on the side of the driver's seat with respect to the elbow rest and is integrally configured, for example, when the switch mounting panel is provided on the front side of the elbow rest and is integrally configured. Compared to this, the switch mounting panel is located in the front part of the fender, so it does not get in the way when getting on and off, and when looking back to control the elevation of the ground work equipment, Compared to the case where it is installed on the front side of the elbow rest, it is closer to the driver's side, making it easier to operate.In addition, the operation surface of the switch mounting panel faces the driver's seat, making it even easier to operate. It has the advantage of being carried out.

Embodiments of the present invention will be described below based on illustrative drawings.

The tractor consists of a pair of left and right front steering wheels 1,
1 and left and right rows of driving rear wheels 2, 2, and a driving section 3, a transmission 5 interlocked with the engine 4, and a hydraulically driven link mechanism 6 at the rear of the vehicle body. A rotary plate device I as an example of a ground work device I is removably connected to the towing vehicle via the link mechanism 6, and the mission 5 and the human power section of the tilling device 7 are connected by a rotating shaft 8, Thus, the tilling device 7 is raised and lowered by the link mechanism 6, and the output of the engine 4 is transmitted to the tilling device 7 via the rotating shaft 8.

a change in plowing depth due to a change in the rotational speed of the engine 4 due to a change in the driving resistance of the rear wheels 2, 2 and a change in the amount of vehicle body subsidence;
In addition, the link mechanism 6 is adjusted based on the initially set control correction value according to the initially set plowing depth value and the softness and hardness of the soil, that is, the ratio between the amount of change in the rotational speed of the engine 4 and the amount of lifting/lowering operation of the tilling device 7. The tilling device I is configured to be automatically controlled to raise and lower by operating the tiller I, and there are switches for performing the control, namely, a dial type switch 9 for setting the tilling depth, and a dial type switch for setting the correction value. switch 1
0, a dial switch 11 for switching the control device between an operating state and a non-operating state, and a snap switch 12 for operating the control device in the direction of raising and lowering the tilling device.
is installed in the driving section 3.

To configure the driving section 3, a driver's seat 14 is disposed between a fender 13a for the left rear wheel 2 and a fender 13b for the right rear wheel 2, and elbows are provided on each of the left and right sides of the seat 14. The right elbow rest 15 is provided with rests 15a and 15b.
The switches 9 and 10°lL12 are disposed on a switch mounting panel 16 which is integrally constructed with the switch mounting panel 16.

The switch mounting panel 16 is attached to the clothing elbow rest 15.
It is located on the lateral side of the driver's seat 14 side with respect to b, and is integrally constructed, and its operation surface faces toward the driver's seat 14 side.

Each elbow rest 15a, 15b is attached to each fender 13.
It is fixed to parts a and 13b.

FIG. 4 shows another embodiment of the elbow rest 15b that is integrated with the switch mounting panel 16, and includes a base portion 17 for fixing the elbow rest 15b to the fender 13b and a storage space provided on the base portion 17. It consists of a swingable opening/closing lid and door rest part 19 for the space 18.
