Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a fuel refueling device for a moving vehicle such as a tractor.

[Prior Art] Conventionally known ones, for example, a fuel tank arranged so as to be sandwiched between left and right fenders as described in Japanese Utility Model Laid-Open No. 58-118019, and Japanese Utility Model Laid-open No. 58- 106601
Some of them, such as those disclosed in Japanese Patent Publication, cause a breather pipe of a fuel tank to be released to the atmosphere via a support column.

[Problems to be Solved by the Invention] By the way, the former device does not have a refueling port provided in the safety frame, but the refueling port is provided in the middle part of the left and right rear columns, which makes refueling operation difficult. In particular, there is a drawback that the refueling work is hindered when the working machine is attached.

Also, in the latter type, since the fuel tank is located relatively low and the breather pipe of the fuel tank is installed inside the strut in front of the seat, the fuel tank should not be touched against lumps of stones or stones. Therefore, there is a problem that the driver may be uncomfortable during the work because the driver is damaged by the odor of the fuel discharged from the breather pipe.

[Technical Means for Solving Problems] This invention is proposed in view of the above problems, and
The following technical measures were taken. That is, in a moving vehicle with a safety frame that is provided with a front strut and a rear strut that are erected so as to surround the seat, and the upper portions of these strut are connected by a ceiling frame, a fuel tank is arranged between the rear strut. A fuel filler port is provided at the bottom of the rear strut on one side, and the fuel filler port and the fuel tank are connected by a pipe, while a breather pipe and a breather pipe are provided in the rear strut on the other side. The fuel refueling device for a moving vehicle is characterized in that an opening is formed in the lower part of the rear pillar on the side where the fuel refueling device is located.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First, the structure will be described. Reference numeral 10 is an agricultural tractor, which is provided with front wheels 11 and rear wheels 1 at front and rear parts of the machine body, and a front frame is provided between them.
12, the clutch housing case 13, the transmission case 14 and the like are connected by a machine frame.

An engine 15 is mounted on the front frame 12, and its upper side and lateral sides are covered with a bonnet 16. Rear axle cases 17, 17 are projectingly provided on both left and right sides of the transmission case 14.

The upper and inner sides of the rear wheel 1 are covered with fenders 2 and 2, respectively, and a seat 18 is provided between the fenders.

Reference numeral 19 denotes a handle, which is provided so as to project rearward and upward from an instrument panel 20 provided at the rear of the bonnet 16.

Reference numeral 21 is a floor, and 22 is a cover that covers the upper side of the clutch housing case 13. 5 is a safety frame, 2 front columns
3 and 23, rear columns 3 and 4, and a ceiling frame 24 connecting the upper portions of these columns.

Reference numeral 25 is a mounting bracket provided on the side wall of the clutch housing case 13, and supports the lower portions of the front columns 23. The rear columns 3 and 4 are formed of rectangular hollow pipes, and seat plates 26, 26 are fixed to the lower ends thereof. Reference numeral 27 is a reinforcing frame having a U-shaped cross-section whose lower part is open, and connects the left and right rear columns 3 and 4.

As shown in FIG. 1, a connection pipe 28 protruding inward and outward is fixed to the lower portion of the left rear support column 3, and a fuel filler port 7 is provided on the outer side thereof, and a cap 29 is attached to the fuel filler port 7. It is installed. A fuel tank 6 is provided between the left and right rear columns 3 and 4, and a pipe 30 made of an elastic material such as a rubber material is attached to the upper portion of the fuel tank 6, and the outer ends of the pipe 30 are connected. It is connected to pipe 28.

On the other hand, on the right side of the fuel tank 6, as shown in FIG. 2, a ventilation pipe 31 is attached, a breather pipe 8 is connected to this ventilation pipe 31, and the breather pipe 8 is inserted into the right rear support column 4. It extends upwards.

Further, a seat plate having a cutout 9 at the lower end of the right rear support column 4
26 is fixed and configured so that the air inside and outside the support column 4 flows.

[Advantageous Effects of the Invention] Since the present invention is configured as described above, it has the following technical effects.

That is, since the fuel tank is arranged between the rear columns of the rigid safety frame, it is possible to prevent damage to the fuel tank even when the tractor falls, which enhances safety, and is There is no fear of damaging this by touching it.

Moreover, a fuel filler port is provided on the strength member called the rear strut,
While connecting this and the fuel tank with a pipe, a breather pipe that communicates with the fuel tank is provided in the rear strut on the other side, so the arrangement configuration of the fuel tank and its peripheral members becomes rational, In particular, the breather pipe is provided at a position located rearward with respect to the seat, and since an opening is formed in the lower portion of the rear pillar, a part of the fuel gas emitted from the breather pipe does not impinge on the driver, A comfortable operating space can be secured.
