Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing / sorting device for threshing cut grain culms in a combine or the like and for sorting the grain.

[0002]

2. Description of the Related Art Generally, this type of threshing and sorting apparatus has a swinging and sorting mechanism that swings in the direction of the axis of the handling barrel at the bottom of a handling chamber containing the handling barrel. The end part is arranged so as to look into the sorting chamber formed at the rear of the handling chamber, while the first receiving gutter and the second receiving gutter are disposed below the swing sorting mechanism and the swing sorting is performed. As is well known, a structure in which a Karafu Juan is provided so that the wind is blown from below the mechanism is known (for example, Japanese Utility Model Publication No. 57-32681).

[0003]

By the way, in the sorting chamber of this type of threshing and sorting apparatus, straw dust and the like will be stagnated due to the blowing of the wind from the Kara Min Juan. It is necessary to regularly inspect and clean the rear end of the swing selection mechanism that looks into the room.

However, in the conventional threshing sorting apparatus, since the sorting chamber has a closed structure, it is extremely difficult to inspect and clean the sorting chamber and the rear end of the swing sorting mechanism looking into the sorting chamber. There was a problem to say. The present invention relates to a recent threshing selection device, for example, the actual Kaihei 1
As disclosed in Japanese Patent No. 167840, a side plate forming one side surface of the handling chamber is provided with a feed chain, and the side plate is configured to be openable and closable so that the handling chamber can be opened. Focusing on the point, the technical problem is to solve the above problem by utilizing this.

[0005]

In order to achieve this technical object, the present invention provides a swing sorting mechanism below a handling chamber provided with a feed chain along one side surface and a rear end portion of the swing sorting mechanism. In the threshing and sorting device, which is arranged so as to look into the sorting chamber formed at the rear of the handling chamber, the first receiving gutter, the second receiving gutter, and the Karafu Juan are disposed below the swing sorting mechanism. The side plate on one side of the handling chamber and the side plate on one side of the sorting chamber are integrated into a side member, and the feed chain is attached to the side member, while the side member is attached with a pin. It is configured so that it can be opened outward and rotated about the center.

[0006]

In this structure, the front surface of the handling chamber can be opened and the front surface of the sorting chamber can be opened at the same time by opening and rotating the side member provided with the feed chain outwardly about the pin. It can be opened. Therefore, according to the present invention, it is possible to extremely easily inspect and clean the handling chamber, and it is also possible to extremely easily inspect and clean the sorting chamber and the swing sorting mechanism.
