Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain culm feeding device for passing a harvested grain culm plant from a reaping section provided in front of a threshing section to a feed chain in the threshing section.

[0002]

2. Description of the Related Art Conventionally, in a combine equipped with a threshing section composed of an under-type feed chien, the vertical transfer chain of the cutting section transfers the root of the cut grain culm to the starting end of the feed chain. Various measures have been taken to ensure smooth feeding to the threshing section. As an example of this means, a feed guide rod that extends the starting end portion of the feed chain to the front side and can switch between the facing position on the extending part and the non-opposing position retracting upward from the extending part. It was developed to provide a smooth operation of grain culm inheritance from the vertically-conveyed chain and to facilitate the supply of hand-handled culm. If the handling depth is adjusted by moving the terminal end up and down with the waving point as the fulcrum, the distance between the end of the vertical conveying chain and the feeding guide rod will fluctuate, and the grain stalks will stagnant or culm will occur. And the inheritance becomes defective.

[0003]

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, the present invention has the above-mentioned drawbacks.
Even if the long and short culms of the vertical transport chain are adjusted by adjusting the handling depth, the end of the vertical transport chain does not change and the interval of the feed guide rod does not change, and the transfer of the harvested culm to the feed chain is always smooth. It was created for the purpose of becoming

[0004]

SUMMARY OF THE INVENTION As a means for achieving the above object, the present invention extends a leading end portion of an under-type feed chain forward and connects a supply guide rod on the extension portion. The vertical transfer chain is installed so that it can be adjusted up and down with the end as a fulcrum, and the harvested grain culm source is passed between the extension and the supply guide rod. A structure in which an adjusting member is provided so as to project toward the supply guide rod, the leading end of the adjusting member is engaged with the wain, and the starting end of the supply guide rod is vertically interlocked by the vertical adjustment operation of the vertical conveying chain. It is characterized by having done.

[0005]

With this construction, the stock of the harvested culm that is conveyed is placed on the extension of the feed chain from the end of the vertical conveying chain, and is pushed by the supply guide rod to be in a sideways posture. The starting end of the pinch rail is inherited, and at this time, the vertical conveying chain is moved up and down with its end as the fulcrum according to the long and short culms of the harvested culm, and the handling depth is increased. When the adjustment is performed, the adjusting member operates integrally with the vertical movement of the vertical conveying chain, and the starting end of the supply guide rod is interlocked vertically.

That is, when the harvested grain culm is a long culm, the vertical transport chain is moved upward, and this upward movement reduces the interval between the end of the vertical transport chain and the feed guide rod, and the grain stalk. However, the adjustment member operates integrally with the vertical transport chain, the end of the vertical transport chain does not change the gap between the feed guide rods, and the transfer is smoothly performed.
When the harvested culm is short culm, the vertical transport chain is moved downward, and this causes the above interval to be increased on the contrary to cause culm spillage, but the adjusting member is integrated with the vertical transport chain. And the feed guide rod is moved downward, the above interval does not change, and the transfer of grain culms becomes smooth.

[0007] When performing manual work,
When the supply guide rod opposite to the extension of the dochien is retracted upwards, the top of the extension is opened, and hand-crop culms are sequentially supplied to the opened place for manual handling.
