Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel tank refueling device for a mobile agricultural machine.

[0002]

2. Description of the Related Art Conventionally, a refueling device for a mobile agricultural machine has been used as an actual flatbed 2
As indicated by -6520, an expansion part is provided near the inlet of the fuel tank to prevent the fuel from spilling by slowing the speed of the fuel approaching the supply port during fuel supply.

[0003]

However, in the refueling device having such an inflating portion, it is necessary to insert the slender refueling cylinder or the tip of the refueling gun straight to the inner part when refueling, and to insert it obliquely. If it comes in contact with the bottom of the expansion section, the fuel gun will lose its hold and fall, or the fuel flow from the expansion section to the small-diameter section inlet will cause bubbling due to turbulent flow, which will slow the fuel flow to the fuel tank. There was a problem such as spilling fuel from the supply port.

[0004]

The present invention has taken the following technical means in order to solve the above problems. That is, in a fuel supply device in which a tank port is opened on the upper surface of a fuel tank, a fuel supply port is provided above the fender, and the tank port and the fuel supply port are connected by a fuel cylinder, the tank port and the fuel supply port are connected. The fuel tank refueling device for a mobile agricultural machine is characterized in that the mouths are connected in a substantially straight line, and the fuel supply ports are provided with opening / closing caps.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show the mobile agricultural machine 7,
The mobile agricultural machine 7 has an engine 11 mounted in a hood 10 at the front of the machine body. This engine 11 is a fuel tank 1
The fuel fed in is burned to generate rotational power, and the rotational power is appropriately decelerated by the transmission mechanism of the transmission case 12 to be transmitted to the front wheels 20 and the rear wheels 18, and the rotational angle is adjusted according to the turning angle of the handle 21. The front wheel 20 is rotated left and right to travel.

The fuel tanks 1 are disposed on the left and right sides of the mission case 12 below the machine body. As shown in FIGS. 2 and 3, the bottom portions of the left and right fuel tanks 1A and 1B provided in the lower portion of the floor 13 are extended toward the center of the airframe, and are fan-shaped left and right extending portions 8A and 8B in plan view. Is provided. The extending portions 8A and 8B are tapered and are formed so as to cover the lower portion of the mission case 12. Further, connect the ends of the left and right extending portions 8A and 8B to the hose 1.
By providing the extending portions 8A and 8B on the left and right fuel tanks 1A and 1B which are connected by 4 and fixed by the band 15,
Compared with the conventional type, the capacity of the tank is increased and a large amount of fuel can be filled. Moreover, since the extended portions 8A and 8B are provided in the extra space so as to cover the lower portion of the mission case 12, the grounded space of the fuel tank 1 does not increase. In addition, the distance between the left and right fuel tanks 1A and 1B is shortened by the extended portions 8A and 8B, and the shape of the connecting hose 14 can be reduced, and the structure of the connecting portion can be simplified.

The fuel tank 1 is made of synthetic resin, and the lower part of the fuel tank 1 prevents collision of flying stones splashed from the ground.
A protective cover 16 is attached to the bottom of the fuel tank 1. The protective cover 16 is provided so as to cover the fuel tank 1 and the extended portion 8 thereof, and is arranged at a constant interval according to the inclination of the bottom surface of the fuel tank 1. The left and right protective covers 16 are open at the center of the fuselage, and when mud adheres to the gap between the bottom of the fuel tank 1 and the protective cover 16,
It can fall out easily by dropping naturally or by releasing water. Further, when the machine body rolls during work in the field, the bottom surface of the fuel tank 1 and the protective cover 16 are inclined, so that contact with the ground can be avoided.

A breather port 9 and a tank port 2 are formed on at least one of the upper surfaces of the fuel tanks 1A and 1B, and a tubular shape is formed around the tank port 2 toward a fuel supply port 4 described later. A protrusion 27 is provided. FIG.
The one shown by means the fuel cylinder 5 in which the protrusion 27 of the fuel tank 1 extends to the recessed portion 22 of the fender 3.
An opening / closing cap 6 is attached to the fuel supply port 4 at the upper end of the fuel cylinder 5.

In the structure shown in FIG. 3, the fuel cylinder 5 is a separate elastic hose 28, and the lower end of the elastic hose 28 and the upper end of the protrusion 27 are connected by a band 26. here,
As shown in FIG. 4, the filter 17 is attached to the connecting portion so that most of the mesh at the lower end thereof projects into the fuel tank 1 and the large-diameter outer peripheral portion of the upper end is held and attached to the upper edge of the projecting portion 27 of the tank 2. . When replacing the filter 17, remove the band 26 and take out the filter 17
Is inserted into the protrusion 27, and the fuel hose 28 and the band 26 are fastened together. The fuel supply port 4 has a straight tube shape, and an upper end portion of the fuel supply port 4 is provided so as to project in a recessed portion 22 provided in the front wall of the fender 3. The central portion of the fuel supply port 4 is bolted by the stay 24 along the back side of the side surface of the fender 3,
The upper end of the fuel hose 28 is fitted into the lower end of the fuel supply port 4 and is locked by the band 25. From the above,
The tank port 2, the elastic hose 28, and the fuel supply port 4 are arranged in a substantially straight line.

Here, the fuel cylinder 5 is connected to the fuel tank 1A.
-Although it has been described that it is attached to one side of 1B, it may be provided on the left and right as follows. Although the fenders 3 are provided on the left and right sides, the recessed portions 22 and 22 are provided on the front walls of the left and right fenders 3 and 3, and the fuel tank fuel filler port 4 and the fuel cap 6 are provided on each of them. Then, the tank port 2 is provided on the upper surfaces of both the fuel tanks 1A and 1B, and the tank port 2 and the fuel supply port 4 are connected as described above. In this way, if it is configured to be able to refuel from both the left and right sides, excessive swirling is not required in the field, and if both fuel caps 6 are opened and fuel is supplied from one, the other produces a breather effect and fuel injection Can be done faster.

[0011]

As described above, in the fuel tank refueling device of the present invention, the tank opening is formed on the upper surface of the fuel tank, and the fuel supply opening is provided on the fender above the fuel tank. A fuel supply device for a mobile agricultural machine, characterized in that the tank port and the fuel supply port are connected in a substantially straight line, and the fuel supply port is provided with an opening / closing cap. Since the tank refueling device is configured, stable and quick refueling can be performed without bubbling near the fuel supply port when fuel is supplied, and the refueling cylinder and the refueling gun can be easily fixed.
