Description

[Detailed description of the invention] This invention is a combine harvester equipped with a pair of left and right crawler running devices, and the fuel tank mounted on the running section frame can be moved to the bottom of the combine harvester in its normal running position without lifting the machine. This relates to a fuel tank mounting device that allows for easy attachment and detachment of the fuel tank. In general, in combine harvesters etc. equipped with running frame, it is desirable to install the fuel tank by making effective use of the blank space between the frames in order to increase the capacity of the fuel tank and lower the center of gravity of the machine as much as possible. However, conventionally, in a combine harvester that is equipped with a pair of left and right crawler traveling devices, and in which the front and rear track frames of the pair of left and right crawler traveling devices are connected by a cross beam frame to form a running section frame, generally the crawler traveling devices are Because the ground height of the orbital frame is low, it is difficult to remove the fuel tank mounted on the running part frame from below while the aircraft is in its normal attitude, and the same applies when installing the removed fuel tank. It is. For this reason, when inspecting and cleaning the fuel tank, when installing and removing the fuel tank, it is necessary to lift the aircraft with a crane or perform the work in a pit, which is not an easy task. , which caused various inconveniences.

In view of the above-mentioned circumstances, the present invention has been developed by configuring the fuel tank mounting part of the running frame to be higher than other parts, making it easy to access the fuel tank from below while the aircraft is in its normal running position. It is an object of the present invention to provide a mounting device for a fuel tank in a combine harvester, which can be attached and detached from the fuel tank, and which allows inspection and maintenance of the fuel tank to be carried out easily and quickly.

The structure of the present invention will be described with reference to an embodiment shown in the drawings. Reference numeral 1, 1 is a pair of left and right crawler running devices in a combine harvester, and 2, 2 is a track frame thereof, in front of the track frame 2, 2. The running section frame 4 is formed by connecting the section and the rear section with cross beam frames 3, 3, respectively. The track frames 2, 2 of the pair of left and right crawler traveling devices 1, 1 are each provided with a driving wheel 5 and an idler wheel 6, and a crawler 7 is suspended between them, and 8 is a plurality of rolling wheels. It is.

The pair of front and rear cross beam frames 3, 3 constituting the running section frame 4 are bent upward at their intermediate parts 3a, 3a, so that the ground clearance h _A of that part is higher than the ground clearance 1 of both ends. A fuel tank 9 is removably attached between intermediate portions 3a, 3a of the pair of front and rear cross beam frames 3, 3.

That is, 10 is a tank mounting body that fits and fixes the fuel tank 9, and the tank mounting body 10 is
One end thereof is locked to the locking guides 11, 11 attached to the intermediate part 3a of one of the cross beam frames 3,
In addition, by fixing the other end to the mounting plates 12, 12 attached to the intermediate portion 3a of the other cross beam frame 3 with respective mounting bolts 13, it can be freely attached and detached between the front and rear pair of cross beam frames 3, 3. ing. The fuel tank 9 is fitted into the tank mounting body 10, and the flange portion 9a is fixed to the mounting body 10 by a plurality of mounting bolts 13'. 14 is a fuel supply pipe, 1
5 is a joint pipe, and the oil supply pipe 14 and the oil intake port 9b of the fuel tank 9 are connected via a joint pipe 15, and 16 is a fixing clamp thereof. 17 is an oil amount gauge. Note that the height including the fuel tank 9 and the joint pipe 15 is h _B , but
Ground height of intermediate parts 3a, 3a of cross beam frames 3, 3
h _A is higher than the height h _B of the fuel tank 9 .

Reference numeral 18 denotes a machine frame, and the machine frame 18 is connected to the running part frame 4 by a plurality of supports 19.
The combine harvester is supported and fixed on the machine frame 18, and devices required for the combine such as a threshing device and a driving device are mounted on the machine frame 18.

In the present invention configured as described above, the fuel tank 9 is fitted and fixed to the tank mounting body 10, and one end of the tank mounting body 10 is locked to the locking guides 11, 11 from the bottom of the fuselage. By fixing the ends to the mounting plates 12, 12 with mounting bolts 13, it is mounted between the pair of front and rear cross beam frames 3, 3 of the running section frame 4. and,
To remove the fuel tank 9 mounted in this way, attach the tank mounting body 10 to the mounting plate 12,
If the mounting bolt 13 fixed to the tank mounting body 12 is removed, one end of the tank mounting body 10 will be attached to the locking guides 11, 11.
Since the aircraft is tilted downward while being locked to the tank mount, if the tank mount 10 is pulled in the direction of the inclination, the tank mount 10 will be released from the locking guides 11, 11, and the fuel tank 9 will be attached to the tank mount. It can be removed from the fuselage together with 10, and therefore inspection, cleaning, etc. can be easily performed.

By the way, the intermediate portions 3a, 3a of the pair of front and rear cross beam frames 3, 3 to which the fuel tank 9 is attached
Since the ground clearance h _A of the is higher than the height h _B of the fuel tank 9, when attaching and detaching the fuel tank 9 as described above, keep the aircraft in its normal running position and make sure there are no obstacles from below. No need to worry, and it can be done easily.

Note that even if the height above the ground of the intermediate portions 3a, 3a of the pair of front and rear cross beam frames 3, 3 is increased, the traveling section frame 4 can still maintain the position of the pair of left and right crawler traveling devices 1,
By reducing the height La between the upper and lower surfaces of the track frames 2, 2 and the crawler 7 of 1, and widening the distance Lb between the upper surface of the crawler 7 and the machine frame 18, it is possible to prevent mud from clogging therebetween. Furthermore, the center of gravity of the aircraft can be further lowered to improve the stability of its running attitude.

In short, the present invention includes a pair of left and right crawler traveling devices, and connects the front and rear track frames of the left and right pair of crawler traveling devices with a cross beam frame to form a traveling section frame, and the front and rear track frames of the pair of left and right crawler traveling devices are The horizontal beam frame is formed so that the ground clearance at the middle part thereof is higher than the ground clearance at the left and right ends, and the fuel tank is removably installed between the middle parts of the pair of front and rear cross beam frames. The height of the mounting part above the ground is higher than other parts, and the fuel tank can be easily installed and removed from the bottom while the aircraft is in its normal running position, making inspection and maintenance work easy and quick. It has a useful practical effect.
