Description

[Detailed description of the invention] The present invention is concerned with modifying the structure of the driving section of a tractor, in particular, the location where switches are installed.The invention aims to improve the structure of a tractor's drive unit, in particular, by modifying the location where switches are installed. The purpose is to prevent unexpected operations caused by the switch, and to simplify the structure around the operating section by selecting the locations where switches are installed.

The tractor driver structure according to the present invention is a tractor in which a driver's seat is arranged between the rear wheel fenders.
A switch box with switches mounted on the top surface is attached to the side of the fender next to the driver's seat, and the switch box is provided with a lid that can be opened and closed to cover the top surface of the switches, and the top surface of the lid is flat. It is characterized by being formed into an elbow rest.

In other words, by simply adding a lid to cover the switches, the action of the lid can prevent rainwater from splashing on the switches and preventing the worker's body from touching them. I achieved my goal.

Furthermore, since the switch box is provided on the side of the fender on the side of the driver's seat, the switch box can be used as an elbow rest. This has the advantage that the area around the seat can be configured more compactly than when it is provided nearby.

Hereinafter, embodiments of the present invention will be described based on illustrative drawings.

The tractor consists of a pair of left and right front steering axles 1,
1, and a pair of left and right 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 tilling device 7, which is an example of a working device, is detachably 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 through a rotating shaft 8, so that the 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, based on the control correction value initially set according to the initially set plowing depth value and the softness and hardness of the soil, that is, the ratio of the rotational speed change amount of the engine 4 and the lifting operation amount of the tilling device 1,
The link mechanism 6″f: is configured to automatically control the raising and lowering of the tilling device 7 when operated, and includes switches for performing the control, that is, a dial switch 9 for setting the tilling depth, and a correction value. A dial-type switch 10 that is embarrassing to set, a dial-type 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 arranged between a fender 13a for the left rear wheel 2 and a fender 13b for the right rear wheel 2, and an elbow rest 15 is attached to the left fender 13a. The mounting member 16 for the switches is attached to the right fender 13b on the side of the driver's seat 14.
It is attached to the side part.

The switch mounting member 16 includes a switch mounting surface on the upper surface and a mounting surface on the fender 13.
A lid 18 that can swing up and down to cover the switches is attached to the switch box 17 fixed to the switch box 17.

The lid 18 is normally kept closed to prevent rainwater from splashing on the switches or accidental contact with the worker's body, and the top surface of the lid 18 is flattened to be used as an elbow rest. It is.

Also, in the closed state, the lid body 18 is closed to the switch box 1.
Switch box 17 so that it is fitted externally to switch box 17.
The fire prevention effect can be further enhanced by forming a step at the joint between the switch box 1T and the cover 18, or by making the inner diameter of the cover 18 larger than the outer diameter of the switch box 1T.
