Description

[Detailed Description of the Invention] The present invention relates to a fuel tank mounting device for an engine in a riding type mobile agricultural machine such as a combine harvester.

Conventionally, fuel tanks installed on combine harvesters, etc. were often mounted exposed above the engine, as shown by the imaginary line in Figure 1, but with this method, the tank was located at a high position, so the fuel It is very inconvenient to replenish the pump, and it is easily damaged because it is constantly exposed to vibrations from the engine directly below it.Also, since it protrudes to the outside, it has defects such as deformation when it comes into contact with objects.

The purpose of this invention is to improve the above-mentioned conventional defects.When installing a fuel tank in a step frame below the driver's seat of a riding type mobile agricultural machine such as a combine harvester, anti-vibration rubber is installed on the step frame. Place the step plate through the
By mounting the fuel tank on the lower surface of the step plate in a suspended manner, the fuel tank can be built into the vibration-proof structure by effectively utilizing the space within the step frame, and the fuel replenishment operation is facilitated. It is something.

Hereinafter, an embodiment of the present invention will be explained with reference to FIGS. 1 to 4. In the figure, 1 is a combine machine base, which is located between a drive wheel 2 at the front of the machine and an idler wheel 3 at the rear of the machine. It is supported by a crawler 5 which is stretched across a plurality of roller wheels 4. Reference numeral 6 denotes an operation panel erected at the front end of the machine base 1. 7 is a step frame formed at the front part of the machine base 1;
The frame 7 is formed into a box shape with an opening 7a at the top and a storage section 7b inside, and is integrally fixed to the machine base 1 at the bottom. 8 is the opening 7
This is a step plate that also serves as a cover to cover the step plate 8, and is attached to the step frame 7 via vibration-proof rubber 9 provided at the four corners.A fuel tank 10 is attached to the back side of the step plate 8, and a mounting arm 11 is attached to the step plate 8. It is attached in a hanging manner. 10a is a fuel filler plug provided at the fuel filler port 10b at the top of the fuel tank;
is a cap for an opening 8b provided in the step plate 8, and a fuel filler port 10b is located directly below the opening 8b. 12 is an oil drain port, and 13 is an oil supply pipe connected to the engine. 14 is step frame 7
A seat frame is installed upright at the rear of the seat frame, and a seat 15 is provided on the seat frame so as to be able to rise and fall freely. Reference numeral 16 denotes a reaping conveyance section installed in front of the machine stand 1, 17 a threshing machine mounted behind it, and 18 a paddy hopper 19 installed laterally from the threshing machine 17, a paddy hopper 19 installed below the paddy hopper 18. The floor, 20, is the engine installed behind it.

The present invention is constructed as described above, and when operating the aircraft, one sits on the seat 15 on the step board 8 and operates the handle on the operation panel 6. However, when refueling Place the fuel container on the wide step plate 8 and pour the fuel into the fuel filler port 1.
The oil can be poured from the 0b, the oil can be supplied from a low and flat position, and the oil can be operated accurately and easily without leaking into the surrounding area.

In addition, the fuel tank 21 shown in FIGS. 8 to 9
1 is an enlarged view of the conventional one shown by the imaginary line in FIG. Such a configuration has the effect of increasing the strength of the tank itself and cooling the fuel inside.

In addition, in FIGS. 5 to 7, a storage section 14a for the sickle 23 is formed by utilizing the empty space below the seat 15 which is provided in the upper part of the seat frame 14 so that the sickle 23 can be raised and lowered, and the sickle 23 is exposed. It can be stored in this without any problems, and can be easily taken out and put in by opening and closing the seat 15.

Next, in detail about the running part, the crawler 5
is suspended by the structure shown in FIGS. 10 to 11, and a sprocket 4 that engages with an engagement hole of a crawler 5 is attached to a support shaft of an inner/outer rotating wheel 4 adjacent to the drive wheel 2.
b is pivotally supported, and a rotating body 25 made of an elastic body with a wing-like protrusion 25a protruding from the outer periphery is detachably attached to the inner wheel body 4a with a bolt 26 and extends inward. The rotation of the crawler 5 causes the sprocket 4b, wheel body 4a, and rotary body 25 to rotate in conjunction with each other, and has the effect of removing mud that tends to accumulate below the drive wheels 2 in wet fields and increasing the running driving force. The one shown in FIG. 12 has a spiral 27 instead of the rotating body 25, which removes the mud toward the inside of the machine, and similarly to the above example, the running performance in wet fields is improved. It is effective in improving the performance.

According to the present invention, when a fuel tank is installed in a step frame below the driver's seat of a ride-on mobile agricultural machine such as a combine harvester, a step plate is placed on the step frame via anti-vibration rubber, and the step plate is This is a fuel tank mounting device for a mobile agricultural machine, characterized in that the fuel tank is mounted in a hanging shape on the lower surface of the machine, and the tank is mounted in a hanging shape on a step plate supported by vibration isolation. It does not require a separate anti-vibration mounting device for the tank, has a simple structure and can be constructed at low cost, and greatly improves the durability of the tank in a stable state with little vibration.

Furthermore, since the tank is provided on the step plate below the seat, refueling operations can be carried out by placing the oil container on the flat and wide step plate at the bottom, so that refueling operations can be carried out reliably in a comfortable position.

In addition, since the fuel tank is stored in the step frame by making effective use of the empty space, there is no risk of the fuel being heated compared to conventional systems that are placed near the engine, and the tank itself is exposed. It has many practical effects, such as there is no risk of injury due to collision with external obstacles.
