Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving agricultural machine such as a combine for continuously cutting and threshing grain culms.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Laid-Open No. 2-42819 or Japanese Utility Model Laid-Open No. 2-237, when a fuel tray is attached to an oil supply pipe and oil is supplied to a fuel tank, the oil is not supplied from the oil supply port of the oil supply pipe. The fuel flowing out to the tray was received by the tray to prevent the fuel from adhering to other portions.

[0003]

In the prior art, the fuel on the receiving surface leaks from between the sealing surface and the fuel supply pipe by forming the sealing surface of the receiving tray away from the fuel receiving surface of the fuel receiving tray. However, the fuel flowing down from the fuel filler easily leaks from between the sealing surface of the pan and the fuel filler pipe, especially when the fuel filler pipe is formed by synthetic resin molding or the fuel filler pipe is installed obliquely to the receiver. In such a case, there was a problem that the fuel traveled through the fuel supply pipe and flowed down into the machine below the pan to be accumulated.

[0004]

SUMMARY OF THE INVENTION However, the present invention is directed to a mobile agricultural machine in which a fuel tray is attached to a fuel inlet of a fuel pipe provided in a fuel tank and a sealing surface of the tray is formed apart from the fuel receiving surface of the tray. Since the oil filler pipe is provided with a groove into which the sealing surface of the fuel tray is fitted, and the sealing surface of the fuel tray is fitted into the groove of the oil filler pipe, even if the oil filler pipe is made of synthetic resin, Even if the structure is provided, the sealing surface of the pan and the oil supply pipe can be easily sealed, and even if the oil supply pipe has a non-uniform cross-sectional shape, fuel leakage from the sealing surface does not occur. It can be easily prevented.

4) is formed, the fuel receiving surface (41) is inclined so that the upper opening of the discharge port (44) is the lowest, and the lower opening end face of the discharge port (44) has a lower front end and a rear end. It is formed by cutting it diagonally so that the edge becomes higher,
The fuel on the receiving surface (41) is discharged from the outlet (4
4) in the same direction as the discharge port (4
Fuel is dropped along the lower front end side of the lower surface opening of 4),
The fuel dropping locations of the discharge ports (44) are always the same so that the fuel can be surely discharged to the outside of the machine.

A step portion (4) is provided inside the discharge port (44).
5) is formed, the lower surface opening is formed larger than the upper surface opening of the discharge port (44), and the discharge pipe (46) is connected to the discharge port (44).
The fuel in the tray (40) can be discharged to the outside of the machine through the discharge pipe (46) so that the upper end surface of the discharge pipe (46) abuts the stepped portion (45). This eliminates problems such as the discharge pipe (46) becoming higher than the receiving surface (41) due to excessive insertion, or falling out due to insufficient insertion,
The discharge pipe (46) always has an appropriate length for the discharge port (44)
Can be plugged into.

Further, as shown in FIGS. 6 and 9, projections (47) are integrally formed on the lower surfaces of the corners of the step mat (28) made of synthetic resin and having a substantially quadrangular shape in plan view. The protrusions (47) are removably inserted into the holes (48) of the step mat, and the bolts (49) that are provided at the approximate center of the step mat (28) to be freely inserted and removed are screwed and fixed to the steps. Protrusion (47) ... and one bolt (49)
Step (27) using the step mat (2
