Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a structure for supporting a fuel tank of a tractor.

(b) Prior Art The technology of supporting a fuel tank at the bottom of a tractor's dash board has been known for some time.

For example, Utility Model Publication No. 55-111811, Utility Model Publication No. 56-
This is similar to the technology described in Publication No. 23132.

(c) Problems to be solved by the invention In the above-mentioned conventional technology, the mounting base for the fuel tank located inside the dart board was fixed to the clutch housing or the steering gear box fixed to the clutch housing. be.

However, recently, in order to prevent the vibrations of the tractor-mounted engine from being transmitted to the entire aircraft, the engine is mounted on the frame with anti-vibration rubber, and only the engine and clutch housing are supported floating, with other parts placed between the engine and the engine. This led to the use of anti-vibration rubber to reduce vibration and noise.

In such a case, if the lower part of the fuel tank is fixed to the clutch housing fixed to the engine side and the other part to the dash board supported by the frame side, the vibration amplitude of the two will be different, which may cause cracks to form in the mounting part. There is a problem.

In order to solve this problem, the present invention is designed to support the fuel tank only on the fuselage frame side.

(d) Means for solving the problem The purpose of the present invention is as described above. Next, the configuration for achieving the purpose will be explained. In a configuration in which the engine is supported on the left and right fuselage frames 18L and 18R via anti-vibration rubber, the fuselage frame 1
Dash board 2 fixedly supported on 8L and 18R
A fuel tank 1 is disposed inside, and a fuel tank mounting base 5 supporting the fuel tank 1 is supported on a steering gear box mounting base 7, and the steering gear box mounting base 7 is connected to the left and right fuselage frames 18.
It is installed on L and 18R, and also spans over a clutch housing fixed to the rear of the engine.

(E) Embodiment The purpose and structure of the present invention are as described above. Next, the structure of the embodiment shown in the attached drawings will be explained.

Figure 1 is a side view of the fuel tank support, Figure 2 is a full view, Figures 3, 4, and 5 are plan, rear, and side views of the steering gear box mounting base, and Figure 6 is a side view of the fuel tank support. 7 is a side view of the steering gear box, and FIGS. 7, 8, and 9 are a side view, a top view, and a rear view of the fuel tank mounting base 5. FIG.

A dash board 2 is provided at the rear of the bonnet of the tractor, and a fuel tank 1 is fixedly installed inside the dash board 2 below, with only a cap 1a of the fuel tank 1 protruding from the dash board 2.

Further, a steering wheel and its support tube 3 also protrude from the dart board 2.

As shown in FIG. 2, a frame 18L for supporting the engine from the front end to the rear end of the fuselage,
18R is arranged, and the engine is supported in a floating state on these frames 18L and 18R via anti-vibration rubber.

A steering gear box mounting stand 7 is also mounted on the frames 18L and 18R.

Since the steering gear box is installed in a square shape and is open at the bottom, the clutch housing integrated with the engine can be passed through this open part.

Since the clutch housing vibrates with the same vibration as the engine, the steering gear box mounting base 7
It is impossible to solidify.

The shape of this steering gear box mounting base 7 is shown in FIGS. 3, 4, and 5.

A square hole 7a into which the lower part of the steering gear box 4 fits is provided in the center.
The steering gear box 4 is fixed through the mounting holes 7b, 7b, 7b, 7b.

Diagonal stays 8, 8 protrude obliquely forward and upward from the steering gear box mounting base 7. A mounting portion 8a for a fuel filter 9 is fixed to the right side oblique stay 8.

Further, the steering gear box 4 placed on the steering gear box mounting base 7 is also provided with a fixed seat 4a for the fuel tank mounting base 5 on the front part, and the mounting base 5a of the fuel tank mounting base 5 is mounted on this. Placed and fixed.

Mounting stands 5b, 5b of the fuel tank mounting stand 5 are mounted and fixed on the above-mentioned oblique stays 8, 8.

The structure of the fuel tank mounting stand 5 is shown in Figures 7 and 8.
It is shown in FIG. 9 and is configured in an upward "U" shape. Also, these mounting bases 5a, 5b, 5b
is installed protrudingly.

Also, place the fuel tank 1 on this mounting table 5,
The front end of the band 12 is fixed to the front end of the fuel tank mounting base 5 with a bolt 20, and the rear end of the band 12 is fixed with a vertical bolt 14, and the reinforcing plate 5d is fixed with a vertical bolt 14. It is tightened and fixed to the inserted band fixing part 5e.

As shown in FIG. 2, the outlet of the fuel tank 1 is located at the lower end on the left side in the direction of travel, and is led from there to the fuel filter 9 by a valve 13.

10 is a side cover, and a fuel filter 9
The fuel opening/closing knob protrudes to the outside of this side cover 10.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, especially in the case of a tractor with a vibration-proof structure in which a frame is provided and the engine is suspended by a vibrating rod, it is possible to eliminate the situation where the fuel tank is supported from both sides of the engine and the machine body, and it is supported by different vibrating parts. This eliminates the problem of cracks occurring in the mounting part.

Secondly, the steering handle is also supported by both the dash board and the clutch housing, and in order to avoid this situation, the steering gear box mounting stand 7 installed on the fuselage frames 18L and 18R is required. , the steering gear box mounting base 7 is connected to the fuel tank 1.
It was able to be used for the support of
This reduced the number of parts and reduced costs.
