Description

[Detailed Description of the Invention] The present invention relates to a fuel tank for a self-propelled riding agricultural machine, and more specifically, to the arrangement position of the fuel tank.

Currently, many of the self-propelled riding agricultural machines in general use have engines mounted in the front of the running vehicle, and the fuel The tank is placed above the engine or above the rear of the engine, and a steering wheel and driver's seat are provided behind it.

As a result, the height of the front of the vehicle increases, reducing the forward visibility of the driver from the steering wheel position.Furthermore, the fuel tank is more likely to heat up, and there is a risk of ignition if fuel leaks. there were.

However, as shown in Japanese Utility Model Application Publication No. 50-74006, there are some engines in which the fuel tank is located above the rear part of the engine, and the rear part is attached to the steering column. If the steering column is located in the lower half of the vertical length of the steering column and is attached to it, and its vertical length is short and small, but the front and rear width is extremely large and the fuel is accommodated, Due to the large weight at the front, the strength of the attachment to the steering column is low, and as mentioned above, the bonnet is covered with a bonnet that has almost the same height as the engine, which is located low in the front. Therefore, the bonnet is long in the front-rear direction, and has a considerable vertical gap from the top of the engine, and is high in height.
Therefore, the operator's forward visibility is obstructed by the bonnet and becomes poor.For example, in the case of a rice transplanter, this may cause the operator to run the rice transplanter body along the planting row, or to place markers, center lines, etc. When driving along a road, these are difficult to see, making it difficult to run smoothly, and the front part of the car body is high and bulky, resulting in an extremely poor appearance and design. There are drawbacks.

Therefore, in the present invention, the fuel tank is moved away from the engine having a bonnet, and is installed along the steering wheel of the steering wheel, extending to the upper edge of the post, and is made vertically elongated, so that the fuel tank is placed at the front of the vehicle body. The height of the fuel tank is configured to be low so that the operator can have a good forward view from the steering handle position so that various agricultural tasks can be performed easily and reliably, and the fuel tank is configured to have a large storage capacity for fuel. , and protrudes vertically from the top of the bonnet, making it appear as if it were a part of the bonnet, giving it a good appearance and design, and preventing the fuel tank from heating up or leaking from the fuel tank. An object of the present invention is to provide a fuel tank for a self-propelled riding agricultural machine which is designed to prevent the danger of fire.

Embodiments of the present invention will be specifically described below with reference to the drawings.

In the figure, reference numeral 1 is the rice transplanter main body of a riding-type rice transplanter, and this rice transplanter main body 1 has a pair of front wheels 2 and a rear wheel 3 on both left and right sides.
Further, an engine 4 is mounted on the front part, a steering handle 5 is installed upright behind the engine 4, and a driver's seat 6 is further provided behind the steering wheel 5.

Further, a planting work machine 8 is attached to the rear part of the rice transplanter main body 1 via a lift mechanism 7.

The engine 4 is installed at the lowest position with respect to the rice transplanter main body 1, and its upper part is covered with a bonnet 9.

Further, a steering post 11 is provided on the steering handle 5 so as to surround a steering rod 10 that extends up and down, and along the front side of this steering post 11,
A vertically long fuel tank 12 extends from the upper edge of the fuel tank 12 and forms the front part of the steering post 11, and is inclined so that its lower end is located on the engine 4 side and its upper end is located on the steering handle 5 side. , is provided at a higher position than the engine 4 and so as to protrude vertically above the bonnet 9.

A fuel supply pipe 13 is disposed between the lower end of the fuel tank 12 and the engine 4, so that fuel is supplied from the fuel tank 12 to the engine 4.

Note that the reference numeral 14 is a cap of the fuel tank 12, and the reference numeral 15 is a panel provided on the upper part of the steering post 11.

When carrying out rice transplanting work using a riding type rice transplanter having such a configuration, the rice transplanter main body 1 is introduced into a paddy field with the planting work machine 8 raised via the lift mechanism 7, and then the lift mechanism 7 When the planting machine 8 is lowered onto the rice field and run, and the planting machine 8 is activated, the planting machine 8 separates the seedlings into one seedling.
Planted on the surface.

At this time, the operator should sit on the driver's seat 6 and use the steering wheel 5.
The rice transplanter main body 1 runs by operating the rice transplanter main body 1, but the rice transplanter main body 1
In the front part of the engine 4, the fuel tank located at the rear upper part of the engine 4 covered by the bonnet 9 extends along the upper edge of the steering post 11 and projects vertically above the bonnet 9. Since the structure is low, the operator has good visibility in front of the rice transplanter, and can, for example, run the rice transplanter main body 1 along the planting row of seedlings, or see markers or center lines. These are convenient because they are easy to see when driving along the road.

Further, the vertically elongated fuel tank can contain a large amount of oil, and protrudes from the rear upper part of the bonnet 9, giving it a good appearance as if it were part of the bonnet. In addition to being superior in terms of design and design, it is installed apart from the engine 4 and at a higher position than the engine 4, so the fuel tank 12 is not heated.
Even if fuel leaks from the fuel tank 12, the risk of ignition is avoided, fuel is supplied smoothly, and the risk of paper lock is reduced compared to conventional fuel tanks.

In addition, in this example, the case where the present invention is applied to a riding-type rice transplanter was explained, but the present invention is not limited to a riding-type rice transplanter, but can be applied to riding-type tractors and other self-propelled riding agricultural machines. is also applicable in the same way.

As explained above, in the present invention, a tank that supplies fuel to an engine having a bonnet is inclined so that its lower end is located on the engine side and its upper end is located on the steering wheel side, and the tank is tilted so that its lower end is located on the steering wheel side. Since the rice transplanter is configured to extend along its upper edge and protrude vertically above the bonnet, the front part of the rice transplanter body is configured low and the operator's forward view is unobstructed. As a result, rice transplanting work can be carried out extremely easily and reliably, and the above-mentioned vertical fuel tank can store a large amount of fuel, is firmly attached to the post, and is suitable for the engine. It protrudes upward at the rear of the bonnet, giving the appearance of forming part of the bonnet, giving it a good design.In addition, since it is located away from the engine, the fuel tank This has the effect of preventing the danger of fuel heating up or igniting fuel leaking from the fuel tank.
