Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical conveying device for supplying grain culms to a threshing feed chain, which is provided around a fulcrum on the rear end side so as to be swingable in the longitudinal direction of the conveyed grain culms for adjusting the handling depth. The present invention relates to a grain culm transporting unit of a self-removing combine, in which a stock source payout rod for handing over the stock source side is provided between a vertical transport device and a threshing feed chain, and more particularly, to a mounting structure for the stock source payout rod.

[0002]

2. Description of the Related Art Conventionally, the front end side of a stock payout rod is fixed to a vertical conveying device in a cantilevered manner so that the stock payout rod can be vertically moved integrally with the vertical conveying device.

[0003]

However, when the vertical conveying device is swung downward in order to accommodate the short culm, the stock payout rod lowers from the starting end side of the threshing feed chain to move the stock basin side of the short culm. There is a possibility that the short culm may not be supported and may not be properly transferred from the vertical conveying device to the threshing feed chain and may fall, and there is room for improvement in terms of grain culm conveying performance. An object of the present invention is to smoothly and surely supply grain culms from a vertical conveying device to a threshing feed chain regardless of the length of grain culms.

[0004]

A feature of the present invention is that a vertical conveying device for supplying a grain culm to a threshing feed chain is shaken in the longitudinal direction of the conveyed grain culm around a fulcrum on the rear end side for adjusting the handling depth. In a self-releasing combine harvester that is movably installed and has a stock source withdrawing rod for handing over the stock side between the vertical conveying device and the threshing feed chain, the front end side of the stock withdrawing rod is connected to the vertical conveying device with a universal joint. That is, the rear end side of the stock-source payout rod is connected to the threshing device by a universal joint near the transport start end side of the threshing feed chain.

[0005]

In other words, since the front end side of the stock paying-out rod is connected to the vertical transport device and the rear end side is connected to the threshing device near the transport start end side of the threshing feed chain by universal joints, respectively Even if the conveyor culm is swung in the longitudinal direction around the fulcrum on the rear end side for adjusting the height, the front end side of the stock payout rod can be maintained at a position where the culm can be satisfactorily received from the vertical conveyor. The rear end side of the payout rod can be maintained at a position where the grain can be satisfactorily passed to the threshing feed chain, and regardless of the length of the grain stem, the grain feeder is supplied from the vertical conveyor to the threshing feed chain. Can be achieved smoothly and reliably.

[0006]

As a result, regardless of the length of the grain culm, the grain culm can be supplied from the vertical carrier to the threshing feed chain smoothly and reliably by the action of the stock paying rod. We can now provide self-removing combine harvesters.
