Description

[Detailed description of the invention] The present invention relates to a combine harvester, and improves the structure of the engine cooling intake part and fuel tank, and allows the intake part to be attached to the dust-proof porous plate without causing any problems in terms of placement. It is an object of the present invention to effectively suppress dust adhesion with the present configuration, and to supply fuel with a simple configuration.

The characteristic structure of the combine harvester according to the present invention is that a fuel tank and an engine cooling intake part, which have almost the same height and width, are placed above the prime mover and behind the backrest of the driver's seat, and the intake part is connected to the fuel tank and the backrest. The fuel tank and the intake part are arranged side by side in a state in which the overall shape is approximately a rectangular parallelepiped, and the front surface and both side surfaces of the intake part are covered with a dust-proof porous plate-like body. It lies in the fact that it was formed.

The effects of the above characteristic configuration are as follows.

In other words, the intake part is placed in a place between the driver's seat and the fuel tank where there is less dust, and three wide sides, the front and both sides of the intake part, are configured as intake surfaces, so that the intake flow velocity is slow. Furthermore, the front side of the widest intake section faces the backrest of the driver's seat,
By effectively using the backrest part for dust prevention,
Overall, it has become possible to effectively suppress dust inhalation into the intake section without adding any special structure for this purpose.

In addition, by arranging the fuel tank and the intake part in a substantially rectangular parallelepiped shape above the driving part, fuel can be supplied using a gravity flow method with a simple structure without causing any problems in terms of placement. Overall, with reasonable and simple modifications, it has become possible to provide a combine harvester with excellent engine cooling performance and an excellent fuel supply configuration.

Next, an embodiment of the present invention will be described based on FIGS. 1 and 2.

On the right front part of the aircraft equipped with the crawler traveling device 1,
A driving unit 4 equipped with an engine 2 and a radiator 3 etc. integrally connected thereto is mounted, a driver's seat 5 is provided above the driving unit 4, and fuel is provided above the driving unit 5 behind the backrest 5a of the driver's seat 5. A tank 6 and an intake section 7 are arranged, a threshing device 8 is mounted behind them, and a pre-processing section 9 is attached to the front of the machine body for raising and reaping planted stem culms and conveying and supplying them to the threshing device 8. , a combine is configured.

The fuel tank 6 and the intake part 7 are formed by a rectangular parallelepiped diagonally divided into two halves from the front upper edge to the rear lower edge so that the overall shape of the fuel tank 6 and the intake part 7 are approximately rectangular. Moreover, an air intake part 7 is arranged between the backrest part 5a and the fuel tank 6. The front surface 18 and both side surfaces 12, 12 of the air intake section 7 are formed of dust-proof punching metal, and the fuel tank 6 is connected to the air intake section 7 so as to serve as a lid.

A duct 13 that guides engine cooling air from the intake section 7 to the radiator 3 is connected to the radiator 13 via a vibration-proof rubber 14a, so that the vibrations of the engine 2 attached to the fuselage frame 19 via the vibration-proof rubber 14b are transmitted through the duct 13. I'm trying not to get it across.

A refueling opening/closing lid 11 is provided on the upper part of the fuel tank 6, and a fuel supply pipe 15 for supplying fuel to the engine 2 by gravity is connected to the lower part of the fuel tank 6.

Next, another example will be shown.

In order to make the fuel tank 6 and the intake part 7 have an almost rectangular shape as a whole, as shown in FIG. The air intake holes 17 may be provided on the front and both side surfaces of the box-like case 16 constituting the section 7, and each may be shaped like a rectangular parallelepiped divided into equal parts depending on the tank capacity and intake amount. It is also possible to change the shape as appropriate.

Instead of punching metal, various materials that are breathable and prevent dust from passing through, such as wire mesh, can be used, and these are collectively referred to as dustproof porous plates.

The present invention is applicable to combine harvesters with various specifications.
