DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rocking and sorting apparatus for a threshing machine such as a combine.

[0002]

2. Description of the Related Art Conventionally, a chaff sheave fin of an oscillating sorter is mounted so that an angle can be adjusted. This is because a pivoting fulcrum hole and an arc-shaped long hole for regulating the amount of rotation are formed in the left and right side walls of the swinging sorter. Both ends of a fin made of an iron plate are fitted and fixed to a fin receiver made of a synthetic resin having a movement regulating shaft.

[0003]

In the conventional fin mounting structure, a gap between the pivot fulcrum hole and the shaft and a gap between the pivot amount regulating hole and the shaft communicate with the inside of the swinging sorter. There is a problem that the fins and the object to be selected bite into the gap between the fin receiver and the left and right side walls of the oscillating sorter, and the fins and the object to be separated are prevented from rotating smoothly.

An object of the present invention is to provide a swing sorter in which fins are attached to a swing sorter so that rotation is not hindered by dust or a sortable object.

[0005]

According to the present invention, there is provided a rocking and sorting apparatus according to the present invention. A flange having a shaft is provided, and the two flanges have inner surfaces located outside the inner surfaces of the left and right side walls of the swing sorter and outer surfaces located inside the outer surfaces of the left and right side walls of the swing sorter.

[0006]

The fin is rotatably supported outside the inner surfaces of the left and right side walls of the oscillating screen, that is, outside the effective screening width of the oscillating screen. In addition, the flange of the fin acts as a cover for preventing the entry of dust and the sorting object into the rotation support portion, and the flange and the rotation support portion are not in contact with each other, so that no sliding resistance is generated between the flange and the fin. Smooth rotation can be maintained, and rotation can be performed with a lighter force. Further, the number of components can be reduced by integrating the fin and the rotation fulcrum, thereby improving the assembling workability and reducing the manufacturing cost.
