Description

[0001]
BACKGROUND 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 riding rice transplanter.
[0002]
[Prior art]
Conventionally, a fuel tank mounted on a traveling work machine is generally installed at the top of the fuselage, but for small tractors and the like where it is difficult to provide a fuel tank installation sbase at the top of the fuselage, a rectangular tank is used. The fuel tank is attached along the lower surface of the intermediate transmission case disposed between the front wheel and the rear wheel at the lower abdomen of the fuselage.
[0003]
However, when a fuel tank is attached as described above, the fuel tank's refueling port is necessarily located in front of the airframe advancement of the step provided in the operation unit, so that the fuel tank is mounted on the step when refueling. In addition to not being able to perform refueling work, the oil supply port protrudes upward from the side of the fuel tank, so there are obstacles when running over uneven fields and over ridges, standing trees, fluffed grains It was unprotected against collisions with firewood, etc., and left room for improvement in that it was easy to induce damage to the fuel tank and the inability to attach or remove the fuel filler lid.
[0004]
[Problems to be solved by the invention]
The present invention has been devised in view of the actual situation as described above, and an object of the present invention is to refuel the fuel tank while the fuel tank is placed on the step, while reducing the burden on the operator. Work can be easily performed, and by positioning the filler port in the space formed between the step and the fender, the traveling unevenness of the field and obstacles to the filler port can be obtained while the traveling work machine is traveling. It is an object of the present invention to provide a fuel tank for a traveling machine capable of eliminating the contact and preventing damage to the fuel tank itself linked to the contact and inability to attach / detach the fuel filler cap.
[0005]
[Means for Solving the Problems]
In order to solve the problem, the technical means adopted by the present invention is to mount the engine on a traveling machine body having front wheels and rear wheels in a state of being covered with a bonnet, and to perform a driving operation including a steering wheel and a driver's seat behind the engine. A left fuel tank with a refueling port facing upward and a right fuel tank connected to this via a connecting pipe at a position below the step stretched under the driver's seat In the tractor, the fuel filler port of the left fuel tank is formed in a space formed on the outer side of the step, between the front end of the fender that covers the left rear wheel, and the auxiliary step provided sideways of the step. facing at its upper end of the fuel supply port is disposed as a lower than step, especially that in a state of mounting the oil tank on the step, and configured to allow oil through the oil supply port to the fuel tank It is an.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
1 and 2, reference numeral 1 denotes a tractor having a fuel tank according to the present invention. The tractor 1 is mounted on a traveling machine body 2 having a front wheel 1a and a rear wheel 1b with an engine 3 covered with a bonnet 4. In addition, a driving operation unit 5 including a handle 5a and a driver's seat 5b is installed behind the mounting unit 6 and a mounting unit 6 for mounting a working machine (not shown) such as a tillage device on the rear side of the machine body is provided. It is configured to perform tillage work.
[0007]
The traveling machine body 2 is configured by integrally connecting a machine body frame 7 on which the engine 3 is mounted and a transmission case that transmits and supports the left and right rear wheels 1b and 1b from a clutch case (not shown) through an intermediate transmission case. In addition, at the lower position of the flat plate-like left and right steps 8a and 8b stretched on both lower sides of the driver's seat 5b, as shown in FIG. A right fuel tank 12 connected to this via a connecting pipe 11 is provided together with fuel pipes A, tank covers B and other peripheral equipment group C.
[0008]
As shown in FIGS. 4 to 6, the fuel filler port 9 of the fuel tank 10 is located on the outer side of the left step 8 a and is disposed at a low position, and covers the upper surface area of the left rear wheel 1 b. Is placed facing the space portion 15 formed between the front end of the left step 8 and the auxiliary step 14 provided on the side of the left step 8a, and a fuel tank (not shown) is placed on the left step 8a. The fuel tank 10 can be easily refueled.
Reference numeral 9a denotes a cap that is detachably attached to the fuel filler opening 9, 13b is a right fender that covers the upper surface of the right rear wheel 1b, and 14a is a step surface formed on the auxiliary step 14.
[0009]
Since the present invention is configured as described above, when fuel is supplied to the fuel tanks 10 and 12, the cap 9a attached to the fuel filler port 9 of the left fuel tank 10 is first removed, and not shown. The fuel tank is placed on the left step 8a. And if the oil supply hose of the said oil supply tank is inserted in the oil supply port 9, the oil supply operation | work can be performed easily.
[0010]
Further, since the fuel filler port 9 is disposed facing the space portion 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 filler port 9, and the obstacle during the traveling of the tractor 1 An object does not hit the fuel supply port 9, and it is possible to prevent the left fuel tank 10 itself from being damaged and the cap 9a attached to the fuel supply port 9 from being detachable.
[0011]
【The invention's effect】
In short, the present invention mounts the engine on a traveling body having front wheels and rear wheels in a state of being covered with a bonnet, and installs a driving operation unit including a handle and a driver's seat behind the engine, In a tractor comprising a left fuel tank provided with a fuel filler port facing upward and a right fuel tank connected to this via a connecting pipe at a position below a step stretched at the bottom, the left fuel tank The refueling port faces the space formed between the front end of the fender that covers the left rear wheel and the auxiliary step that is attached to the side of the step on the outer side of the step, and the upper end of the refueling port is step is arranged as a lower than, placed in a state of arranging an oil supply tank on the step, because configured to allow oil through the oil supply port to the fuel tank, an oil supply tank on a step State can be refueling the fuel tank, it is possible to easily perform the refueling work while reducing the burden on the operator.
In addition, since the oil filler port is located in the space formed between the auxiliary step and the fender, the bumps on the field and obstacles to the oil filler port are wiped out while the traveling work machine is traveling. It is possible to prevent the damage of the connected fuel tank, the detachment of the cap attached to the fuel filler port, and the like.
