Description

[Detailed Description of the Invention] The present invention provides an engine bonnet that can swing open and close, and a guide member that guides engine cooling air introduced from the intake port of the engine bonnet to an engine cooling radiator. The present invention relates to a structure of a driving part in a combine harvester, which is integrally and swingably attached to the engine bonnet with a partition between a part of the engine bonnet where the radiator and engine are located and a part where the intake port is located.

The structure of the driving part of the combine harvester is such that dust such as straw that is sucked into the engine bonnet together with the engine cooling air is prevented from entering near the engine by the partitioning action of the guide member. The guide member is constructed so that it can be separated from the engine bonnet and the radiator to open the vicinity of the engine and radiator, making it easy to inspect and repair the engine, etc. Conventionally, the guide member was made of iron plate. and
The weight of this guide member requires a great deal of effort to open and close the engine bonnet.

An object of the present invention is to reduce the weight of the guide member.

In order to achieve the object, the present invention is characterized in that the guide member is made of a sheet in the structure of the driving part of the combine harvester described above.

That is, since the guide member is made of a cloth sheet, it is lighter than the conventional sheet made of steel, and the engine bonnet can be opened and closed more easily.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a crawler type traveling device 1,
At the front part of the traveling machine, which has a driving part equipped with an engine bonnet 3 to which a driver's seat 2 is attached, and a threshing part 4, etc., there is a threshing part 4 for raising and reaping planted grain culms, and for removing the reaped grain culms. A combine harvester is constructed by connecting a reaping section 5 for supplying to the harvester.

The driving section is constructed as shown in FIGS. 2 and 3.

That is, the engine 6 is connected to the engine bonnet 3.
The engine fuel tank 8 is disposed on the inner bottom portion and mounted on the traveling body frame 7, and is attached to the top plate portion 3a of the engine bonnet 3 with the fuel filler port side protruding outside the engine bonnet 3.

Then, an engine cooling radiator 9 is disposed in the upper part inside the engine bonnet 3 and is mounted and fixed on the engine 6, and a rotating fan 10 is provided inside the body of the radiator 9. An intake port 12 or 13 with a dust removal screen is provided on each of the front wall portion 3c and the rear wall portion 3d, and cooling air is transferred to the three intake ports 11 by the intake action of the fan 10 and the guiding action of the cloth guide member 14. , 12, 13 into the radiator 9 to cool the engine.

The guide portion 14 is formed and arranged so as to partition a portion of the engine bonnet 3 where the engine 6, radiator 9, etc. are located from a portion where the three intake ports 11, 12, and 13 are located, This partitioning action of the guide member is intended to prevent dust such as straw waste, which is sucked in together with the engine cooling air, from entering the vicinity of the engine 6.

A wind guide 15 that adjusts the suction force by the rotating fan 10 to act almost uniformly on the entire surface of the side wall intake port 11 is disposed on the intake surface side of the radiator 9, and is connected to the fuel tank 8 via a stay 16. It is attached to the bottom of the side wall inlet 11 to prevent local clogging of the dust removal screen with dust.

The engine bonnet 3 is pivotally connected to the fuselage frame 7 so as to be able to swing open laterally outward of the fuselage around the axis of the connecting shaft 17, and the guide member 1
4 is attached to the engine bonnet 3 so as to swing integrally with the engine bonnet 3, and by simply opening and closing the engine bonnet 3, the guide member 14 is moved away from the engine 6 and the radiator 9 to the outside of the fuselage for inspection. , the use state is switched to a state in which the combine harvester 6 and the radiator 9 are close to each other.

To fix the guide member 14, the front and rear side edges of the fuselage body are fastened and connected to the front wall 3c or the rear wall 3d of the engine bonnet 3 together with a presser band plate, and the upper and lower edges are fastened together. Both ends of the connecting wire 18, which are inserted through folded loops formed at the respective locations as shown in FIG. 4, are connected to the bonnet front wall 3c and the bonnet rear wall 3d.
The peripheral edge of the notch hole corresponding to the intake side of the radiator 9 is connected to the stay 19 extending from the top plate part 3a of the engine bonnet 3 by tightening and connecting each part separately to the engine bonnet 3. It is tightened and fixed.

Then, the lower end side edge of the guide member 14 is
Sponge 20 attached to the bonnet side wall 3b
The lower end side of the guide member 14 is sealed by being pressed together with the connecting wire 18 to make a tight contact.

21 shown in FIGS. 2 and 3 is a sponge that seals between the intake side of the radiator 9 and the guide member 14, and 22 shown in FIG. 4 is a sponge that seals between the guide member 14 and the bonnet top plate 3a. It is a partition plate that fills the gap.

The material of the guide member 14 can be changed to various sheets such as a resin sheet other than cloth.
