Description

[Detailed Description of the Invention] The present invention relates to a protective cover structure for a tractor, and aims to provide a wide step space while ensuring safety, and also ensure the rigidity of the protective cover.

In a tractor, a bonnet that covers the engine is provided at the front of the tractor body, and a pitman arm that can swing back and forth is provided on one side of the tractor body at the rear of the bonnet, and the tractor body is attached to the rear of the pitman arm. Some have a step on one side and a protective cover on the front side of the step.

If you install a protective cover on the front side of the step like this,
It can prevent mud, etc. from flying from the front, and at the same time prevent the operator's feet from coming into contact with the pitman arm.
It has the advantage of ensuring safety.

However, in the past, as disclosed in US Pat. No. 3,884,322, for example, only a flat plate-shaped protective cover that sloped upward in the front was provided, so the effective space of the step was limited by the protective cover. There were some drawbacks.

Furthermore, if the protective cover is a simple flat plate, it is difficult to ensure its own rigidity and it will cause shaking, so it is necessary to have a mounting structure that can prevent this.

The present invention solves these conventional problems, and its features are that a bonnet is provided at the front of the tractor body to cover the engine, and the rear side of the bonnet covers the tractor body. In a tractor that is equipped with a pitman arm that can freely swing back and forth on one side, a step is placed on one side of the tractor body behind the pitman arm, and a protective cover is provided on the front side of the step, the protective cover is located at the rear end. A substantially bridge-shaped main body part that is attached so that it is continuous with the step and is formed in a front upward shape until the front end reaches forward of the pitman arm, and the pitman arm is attached from the side to the inner edge side of this main body part. The tractor is provided with a cover portion formed upright to cover the vehicle, the cover portion side being attached to one side of the tractor vehicle body, and the upper end side of the cover portion being wrapped around the rear lower end portion of the bonnet from the outside.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.
In the figure, 1 is a tractor body, 2 is a front wheel 3, and 4 is a fender.

5 is a bonnet that covers the engine, etc., and 6 is a handle, which is supported by a gear box 7 on the tractor body 1 via a support column 8, as shown in FIGS. 2 and 3, and is attached to one side of the tractor body 1. On the other hand, it is interlocked with the front wheel 2 via a pitman arm 10 and a drive link 11 that are swingable back and forth about the sector axis 9, and the front wheel 2 can be steered by the handle 6.

Reference numeral 12 denotes steps attached to both sides of the tractor body 1, and a protective cover 13 is provided in front of each step 12.

Each protective cover 13 has a step 1 at the rear end with a pole 15.
The pitman arm 10 has a substantially bridge-like main body portion 24 that is attached so as to be continuous with the pitman arm 10 and is formed in an ascending front shape so that the front end is located forward of the pitman arm 10.

In particular, the protective cover 13 on the pitman arm 10 side
is provided with a cover part 24 integrally formed in a rising shape so as to cover the pitman arm 10 from the side on the inner edge side of the main body part 24, and the rear inner edge of this cover part 24 is connected to the bolt. 14 to the sidewall of the tractor body 1.

Further, the upper end of the cover portion 16 is wrapped around the rear lower end of the bonnet 5 from the outside.

Note that, of course, the protective cover 13 on the opposite side of the pitman arm 10 also has a rising portion, which is lapped with the bonnet 5 as described above.

Therefore, in this case, since the main body part 24 is continuous with the step 12, a wide step space can be secured, and since the cover part 16 covers the pitman arm 10 from the outside, the main body part 24 is connected to the pitman arm 10. Even though it extends further to the front, safety can be ensured.

Furthermore, since the main body portion 24 and the cover portion 16 have different directions, the rigidity of the protective cover 13 itself is improved.

Furthermore, since the cover portion 16 is wrapped around the bonnet 5 from the outside, the appearance is also improved.

Note that the protective cover 1. -3 is locally formed to be substantially orthogonal to the clutch pedal 17, etc., so that the pedal insertion hole 18 is the minimum necessary hole.

Reference numeral 19 denotes an inverted stay supported between the upper side surface of the bonnet 5 and the front outer end of the protective cover 13, to which a transparent windshield plate 21 is attached via a holder 20.

Reference numeral 22 denotes a main shift lever, and 23 is a PTO shift lever.

As described in detail in the embodiments above, in the present invention, step 12
Since a substantially bridge-shaped main body part 24 that extends continuously to the front of the pitman arm 10 is provided, it is possible to secure a wide step air victory, and since the pitman arm 10 is covered from the outside with the covering part 16, the main body part 24 is pitman arm 1
Even though it extends to the front side of 0, safety can be ensured.

Moreover, since the main body part 24 and the cover part 16 have different directions, the rigidity of the protective cover 13 itself is improved.

Moreover, since the cover part 16 is wrapped with the bonnet 5 from the outside, the appearance becomes better.
