Description

[Detailed description of the invention] This invention is an agricultural combine, in which an engine body is installed at the front of one side of the main body, and a disk-shaped air cleaner is installed on the lateral outer surface of the engine body via a carburetor. For the type that protrudes in the direction, straw waste etc. may adhere to the vaporizer.
This invention relates to a device that prevents intrusion.

The purpose is to prevent damage to the culms of the uncut land that are about to collide with the carburetor while ensuring dust prevention.

In order to prevent straw debris from falling onto the vaporizer from above or collision with uncut crustal culms, it is necessary to cover the top and front surfaces of the storage space for the vaporizer.

Simply covering the upper and front surfaces of the vaporizer storage space with a hard dustproof plate has the disadvantage that uncut culms collide with the front part of the dustproof plate, resulting in breakage of ears and dropping of the rice grains.

In order to overcome this drawback, it is possible to make the front part of the dust-proof board slanted so that its inner edge extends largely forward, but even in this case, the uncut crustal culm is oblique to the front part of the dust-proof board. In addition, the dust-proof plate becomes large and the production cost becomes high.

In order to eliminate the above-mentioned drawbacks, the present invention covers the top surface of the carburetor housing space with a hard dustproof plate, so that the top surface can be covered securely, and the front surface of the carburetor housing space is covered with a flexible hanging film. By covering, the uncut crust culm is softly received by the hanging membrane and is guided out of the vaporizer storage space without causing ear breakage or paddy drop.

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

The drawing shows an agricultural walking combine harvester, which has the following basic structure.

That is, a planted culm weeding tool 2, a raising device 3, a reaping device 4, a rear conveyance device 5, and a threshing machine 6 are arranged in order from the front to the rear of the vehicle body 1. A forced air-cooled engine 7 is disposed at the front lower part of the left half, and a control device 8 is disposed at the rear upper part.

The forced air-cooled engine 7 is equipped with a cooling fan 10, a recoil starter 11, and a dust-proof air intake cover 12 with an open bottom on the front side of a vertical air-cooled side valve engine body 9. An air cleaner 14 is provided to protrude outward to the left, a muffler 15 is installed at the rear left side of the air cleaner 14, and the back surface thereof is configured as a cooling exhaust air blowing surface 16.

The cooling exhaust air blowing surface 16 of the engine 7 faces the lower right quarter of the front wall 18 where the culm supply port 17 of the threshing machine 6 opens.

The upper surfaces of the engine 7 and the muffler 15 are covered with a dustproof cover 19 made of a single iron plate.

This dustproof cover 19 has an upward slope at the rear of the engine body 9.
It is fixed to the mounting bolt 21 of the cylinder head 20 of.

A carburetor housing space 22 is formed between the engine body 9 and the air cleaner 14.

The upper surface and the upper half of the front surface of this carburetor housing space 22 are covered with a dustproof plate 23 made of iron plate, and this dustproof plate 23 is detachably fixed to the left side surface of the dustproof cover 19.

With the dustproof plate 23 removed, the carburetor 13 can be inspected.

The lower front half of the carburetor housing space 22 is covered with a flexible hanging membrane 24 made of nylon, rubber, or cloth and having some weight, and this hanging membrane 24 is fixed to the inner surface of the front edge of the dustproof plate 23.

Grass divider frames 25 extend diagonally rearward and upward from the grass divider 2 at each end of the left and right sides, and the left side weed divider frame 25 is connected to the hanging membrane 24.
The threshing machine 6 passes through the outside of each lower structure of the air cleaner 14.
Reach the front left edge of.

Since the present invention is configured as described above, it has the following effects.

That is, since the upper surface of the carburetor housing space is covered with a hard dustproof plate,
This dustproof plate can be firmly fixed and its top surface can be covered securely.

Moreover, since the front of the vaporizer storage space is covered with a flexible hanging film, the uncut crust culm moving toward the vaporizer is softly received by the hanging film, preventing the ear from breaking or the hulls falling off. will be guided outside the vaporizer housing space.

This makes it possible to reliably prevent dust such as straw waste from adhering to or entering the vaporizer, while also preventing damage to the uncut crustal culm.

In addition, since the hanging membrane can fully demonstrate its function even when facing straight forward, there is no need to turn it diagonally forward and sideways, and it can be made compact with a relatively short width, reducing manufacturing costs. .
