Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a fuel tank cover for a combine harvester.

(Prior Art) Conventionally, in a combine harvester in which an automatic feeding type threshing device is mounted on an underframe equipped with a traveling device and a reaping device is attached to a position in front of the traveling device, a fuel tank is installed in the driver's seat. The provided one is known as Japanese Utility Model Application Publication No. 54-18831.

In addition, an automatic feeding type threshing device is mounted on an underframe provided with a traveling device, and a reaping device is attached to a position in front of the traveling device,
A device in which a dust exhaust port is formed at the exhaust port of the dust exhaust portion and becomes lower toward the rear is also known as Utility Model Publication No. 52-1465499.

(Problem to be solved by the invention) However, the former not only obstructs driving, but also does not contribute in the slightest to threshing performance.

The latter does not mention a fuel tank at all.

(Means for solving the problem) Therefore, in the present invention, an automatic feeding type threshing device 2 is mounted on an underframe 6 on which a traveling device 1 is provided, and a threshing device is installed in a position in front of the traveling device 1. In the attached combine harvester, the fuel tank 26 of the engine is placed on the rear part of the underframe 6, and the upper surface of the fuel tank 26 is covered with a fuel tank cover 28, and the front part of the fuel tank cover 28 is covered with a fuel tank cover 28. High and rear sloping low;
The front part of the fuel tank cover 28 is connected to the bottom wall 27 of the wind selection chamber 20.
The fuel tank cover 28 is connected to the rear end of the combine harvester, and the rear end of the fuel tank cover 28 protrudes rearward from the rear end of the fuel tank 26 and is lower than the upper part of the fuel tank 26. It is something.

Embodiment An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a traveling device consisting of a crawler or the like, and an automatic feeding type threshing device 2 is mounted on the upper part of the underframe 6 of the traveling device 1.

Reference numeral 3 designates a husk supplying chino of the threshing device, 4 a husk culm supplying chino, and 5 a straw transporting chino of the straw transporting device.

An upper mounting frame 7 and a lower mounting frame 8 are pivotally attached to the underframe 6 side of the combine by a pivot 9.

A hydraulic cylinder 10 is installed between the lower mounting frame 8 and the underframe 6, and when the cylinder 10 extends, the upper mounting frame 7 and the lower mounting frame 8 rotate upward together, and the cylinder 10 contracts. Then, it rotates downward at the same time.

The upper back surface of the lifting device 11 is fixed to the protruding tip of the upper mounting frame 7 .

Further, a support frame 12 is provided in the vicinity of the pivot shaft 9 of the upper mounting frame 7, and a tip-side guiding and conveying device 13 and a stock-side guiding and conveying device 14 are respectively fixed to the support frame 12.

The lower attachment frame 8 passes under the lower end of the lifting device 11 and protrudes further forward, and the weeding body 15 is attached to the tip thereof.

Further, the lower end of the scraper 16 is fixed to the rear side of the lifting device 11.

17 is a clipper type cutting blade device.

The internal structure of the threshing device 2 includes a handling barrel chamber provided at an upper position on the front side with respect to the traveling direction T of the machine body, and a handling barrel 18 mounted therein;
The lower surface side of the handling barrel 18 is surrounded by a handling net 19, and a winnowing chamber 20 is formed under the handling net 19.

At the front end of the wind sorting chamber 20, there is provided a wind blower 21 that blows wind toward the rear, followed by a swinging sorting device 22 and an Ichiban conveyor 2.
3. Install a second conveyor 24, etc.

25 is a suction winch. However, the underframe of the combine 6
A fuel tank 26 for the engine is mounted on the rear of the threshing device, and the rear of the threshing device is provided close to the fuel tank 26, and a fuel tank cover 28 is provided at the rear of the bottom wall 27 of the wind selection chamber 20. to cover the upper part of the fuel tank 26.

The front part of the fuel tank cover 28 is connected to the rear part of the bottom wall 27 and is formed as low as it reaches the rear part, and the rear end part extends rearward than the rear end part of the fuel tank 26. It is lower than the upper part of the fuel tank 26, completely surrounds the fuel tank 26, and is formed to smoothly discharge dust and prevent blowback.

(Function) Since the present invention has the above-described configuration, when the traveling device 1 consisting of a crawler moves forward in the T direction, the frontmost weeding body 1
5, the grass is divided by the pulling device 11, the root part is cut by the cutting blade device 17, and the culm supply port of the automatic feeding type threshing device 2 is separated by the tip side guiding conveyance device 13 and the stock side guiding conveyance device 14. 3
to feed and thresh the grain.

The threshed grains are threshed by the handling barrel 18 and then fall through the handling net 19 into the wind sorting chamber 20 at the bottom, and while being swung by the swinging sorting device 22, they are sorted by the wind from the blower winnower 21. The first grain is taken out by the first conveyor 23, the second grain is taken out by the second conveyor 24, and the light straw waste is taken out by the suction winch 2.
It is suctioned away by 5.

Therefore, the dust in the wind selection chamber 20 is guided to the fuel tank cover 28 from the rear of the bottom wall 27 and is discharged outside the machine, but although the fuel tank cover 28 is a cover for the fuel tank 26, it part is joined to the rear part of the bottom wall 27,
The rear end extends rearward from the rear end of the fuel tank 26 and is formed to be lower than the upper part of the fuel tank 26 and completely surrounds the fuel tank 26, so the fuel tank 26 safely, and also allows dust to be smoothly discharged without blowing back.

(Effects) Conventionally, in a combine harvester in which an automatic feeding threshing device is mounted on a platform scale equipped with a traveling device, and a reaping device is attached to the front position of the traveling device, a fuel tank is placed in the operator's seat. The one provided was known as Utility Model Publication No. 54-1883N.

In addition, an automatic feed type thresher is mounted on the underframe equipped with a traveling device, a tact reaping device is attached to the front of the traveling device, and a dust exhaust port is formed at the exhaust port of the dust exhaust section, which becomes lower toward the rear. This was also known as Japanese Utility Model Application No. 52-146549.

However, the former not only obstructs operation, but also does not contribute to threshing performance in the slightest.

The latter does not mention a fuel tank at all.

However, in the present invention, an automatic feeding type threshing device 2 is mounted on an underframe 6 on which a traveling device 1 is provided, and a reaping device is attached to a position in front of the traveling device 1. The fuel tank 26 of the engine is placed on the rear of the engine, and the upper surface of the fuel tank 26 is covered with a fuel tank cover 28. The fuel tank cover 28 is sloped high at the front and low at the rear. The front part of the fuel tank cover 28 is connected to the rear end of the bottom wall 27 of the wind selection chamber 20, and the rear end of the fuel tank cover 28 protrudes rearward from the rear end of the fuel tank 26, and the fuel Since it is used as a fuel tank cover for a combine harvester that is lower than the top of the tank 26, (a) the fuel tank 26 can be easily installed.

The fuel tank cover 28 has two functions: a fuel tank cover and a dust guide.

C. The fuel tank 26 is almost completely protected by the rear end portion of the fuel tank cover 28.

2. There is no blowback of dust.

This effect can be expected.
