Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a culm conveying device for switching and feeding the culm conveying position to a cutter and a knotter or a converging device by expanding and contracting a sandwiching rail provided opposite to the culm conveying body of a thresher. Regarding

2. Description of the Related Art Conventionally, a cutter and a knotter or a bundling device are provided on the lower side of the culm carrier of a threshing machine in the conveying direction, and a nipping rail opposite to the culm carrier is expanded and contracted to remove the culm. The culm conveying device that is switched so as to selectively supply to the cutter and knotter or the focusing device has a movable rail slidable inside a pipe-shaped holding rail that is fixed opposite to the lower surface of the culm conveying body. In addition to supporting the interior, a tension spring is provided to urge it in the extension (conveyance) direction to supply the culms to the knotter, and by pulling the wire provided at the tip of this movable rail against the tension spring. There is a known culm transporting device of a type in which culms are supplied to a cutter by operating in a contracting (counter-transporting) direction.

On the other hand, there has been implemented a wire-operated type culm transporting device in which the movable rail not using a tension spring is expanded and contracted via a wire wound around a roller. The wire is fixed to the front and rear ends of a movable rail supported by the same structure as above, and is wound around a roller pivotally supported at the lower end of the fixed nipping rail, and this roller is operated separately from the driver's seat. The movable rail is forcibly expanded and contracted by winding the wire.

[0004]

However, in the former device of the related art, since the expansion and contraction stroke of the movable rail is long from the cutter to the knotter supply range, in this type of culm transfer device, the spring constant is low, and Since it requires a spring that is strong and has a significantly long compression margin, it is not suitable in practice and is difficult to implement.

Further, in the latter device, the roller pivotally supported by the sandwiching rail is exposed while the culms are being conveyed, and the wire portion connected from this roller to the movable rail end is movable. Since the rail is exposed in a wide range when it is extended, there is a problem that straw during transportation and falling straw waste are easily wound around the above-mentioned both or stagnant. Further, when the operation wire is pulled to try to operate the movable rail forcibly, there is a drawback that the clamp rail is apt to be deformed or damaged.
