DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel tank mounted on a lower abdomen of a traveling work machine such as a tractor or a rice transplanter.

[0002]

2. Description of the Related Art Conventionally, a fuel tank mounted on a traveling work machine is generally installed on the upper part of an airframe. However, in a small tractor or the like where it is difficult to provide a base for installing the fuel tank on the upper part of the airframe, a rectangular shape is used. Is mounted along the lower surface of an intermediate transmission case disposed between the front and rear wheels at the lower abdomen of the fuselage.

[0003] However, when the fuel tank is mounted as described above, the filler port of the fuel tank is inevitably located in front of the body in the step provided in the operation section, so that the fuel tank is refueled when the fuel is supplied. In addition to being able to carry out refueling work by placing it on a step, the refueling port protrudes upward from the side of the fuel tank. However, it is vulnerable to collision with standing corn kernels and the like, leaving room for improvement in that the fuel tank is likely to be damaged, the lid of the fuel filler opening cannot be easily removed, and the like.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and has as its object to refuel a fuel tank with the refueling tank mounted on a step. The refueling operation can be easily performed while reducing the burden on the operator, and the refueling port is located in a space formed between the step and the fender, so that the traveling work machine can travel in the field while traveling. An object of the present invention is to provide a fuel tank for a traveling work machine that can eliminate bumps and bumps and obstacles to a fuel filler port, and prevent damage to a fuel tank itself connected to the fuel filler cap, and prevent the fuel filler cap from being attached or removed. Things.

[0005]

According to a first aspect of the present invention, an engine is mounted on a body frame having front and rear wheels and provided between the front and rear wheels. In a traveling work machine in which a step to a driving operation unit is disposed on a side of an airframe, a fuel tank for supplying fuel to the engine is disposed below the step, and a filler port of the fuel tank is provided. Is arranged at a low position on the side of the step, and as a second technical means,
The fuel supply port of the fuel tank is disposed so as to face a space formed between a front end of a fender that covers an upper surface area of the rear wheel and an auxiliary step provided alongside the step. It is a feature.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. 1 and 2, reference numeral 1 denotes a tractor provided with a fuel tank according to the present invention. The tractor 1 is mounted on a traveling body 2 having a front wheel 1a and a rear wheel 1b with an engine 3 covered with a bonnet 4. At the same time, a driving operation unit 5 including a steering wheel 5a and a driver's seat 5b is installed at the rear thereof, and a mounting unit 6 is provided at the rear of the fuselage so that a work machine (not shown) such as a tillage device can be vertically moved. It is configured to perform tillage work and the like.

The traveling body 2 integrally connects a body frame 7 on which the engine 3 is mounted, a transmission case for transmitting and supporting the left and right rear wheels 1b, 1b from a clutch case (not shown) via an intermediate transmission case. As shown in FIG. 3, the left fuel supply port 9 is provided below the flat plate-shaped left and right steps 8a and 8b which are stretched on both sides below the driver's seat 5b. Tank 1
0 and a right fuel tank 12 connected thereto via a connecting pipe 11 are provided together with a fuel pipe A, a tank cover B, and another peripheral device group C.

The fuel supply port 9 of the fuel tank 10 is shown in FIGS.
As shown in FIG. 6, the front end of the left fender 13a, which is located at a lower position outside the left step 8a and covers the upper surface area of the left rear wheel 1b, is provided alongside the left step 8a. The fuel tank 10 is disposed so as to face a space portion 15 formed between the auxiliary step 14 and the fuel tank 10 (not shown). . 9a is a cap detachably attached to the filler port 9, 13b is a right fender covering the upper surface of the right rear wheel 1b, and 14a is a single step surface formed in the auxiliary step 14.

Since the present invention is constructed as described above,
When refueling the fuel tanks 10 and 12,
First, the cap 9a attached to the fuel supply port 9 of the left fuel tank 10 is removed, and the fuel tank (not shown) is moved to the left step 8
a. Then, if the oil supply hose of the oil supply tank is inserted into the oil supply port 9, the oil supply operation can be easily performed.

Since the fuel supply port 9 is disposed facing the space 15, the auxiliary step 14 including the step surface 14a and the front end of the left fender 13a function as a guard for the fuel supply port 9, so that the tractor 1 travels. An obstacle does not come into contact with the fuel supply port 9 in the inside, so that damage to the left fuel tank 10 itself and inability to attach / detach the cap 9a attached to the fuel supply port 9 can be prevented.

[0011]

In summary, according to the present invention, an engine is mounted on a body frame having front and rear wheels, and a step to a driving operation unit provided between the front and rear wheels is arranged on a side of the body frame. Since the fuel tank for supplying fuel to the engine is arranged below the step and the fuel supply port of the fuel tank is arranged at a low position on the side of the step, the fuel tank is The fuel tank can be refueled while it is placed on the top, and the refueling operation can be easily performed while reducing the burden on the operator. Also, the filler port of the fuel tank is
Since it is located facing the space formed between the front end of the fender that covers the upper surface area of the rear wheel and the auxiliary step that is attached to the side of the step, between the auxiliary step and the fender Since the refueling port is located in the formed space, during traveling of the traveling work machine,
This makes it possible to eliminate irregularities in the field and collisions of obstacles with the fuel supply port, thereby preventing damage to the fuel tank connected to the fuel supply port, inability to attach or remove the cap attached to the fuel supply port, and the like. Etc., which are very useful and novel effects.
