Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-cutting combine, in which grain culms cut over a plurality of rows are combined into a single row and then conveyed to a feed chain in a threshing device mounted on the combine. The present invention relates to an apparatus for transporting the stock portion of a company.

[0002]

2. Description of the Related Art In general, this type of stock transfer apparatus is, for example, as disclosed in Japanese Utility Model Publication No. Sho 57-34911, in which a grain stalk cut from one of a plurality of strips is used.
On the way to the feed chain or the cereal culm vertical conveying device to the feed chain in the main endless chain mechanism, the grain culm cut from the other of the plurality of rows is added to the main chain by the sub endless chain mechanism. It is configured to join while transporting.

[0003] However, in this stock transfer apparatus, grain stalks are likely to be clogged at the confluence of the sub endless chain mechanism with the main endless chain mechanism.
The entire sub-endless chain mechanism is rotatable around its front end so that its end is separated from the main endless chain mechanism, and the rotation operation removes grain stalks clogged at the merging portion. It is configured to be able to.

[0004]

However, in this conventional apparatus, since the sub endless chain mechanism must be configured to rotate as a whole, the structure of the apparatus is considerably complicated and large. At the same time, the weight increases, and at the end of the sub endless chain mechanism, a portion extending substantially parallel to the main endless chain mechanism over an appropriate length is provided. At the initial stage of rotating the entire chain mechanism, the end of the chain mechanism comes to approach the main endless chain mechanism at once, so a large force is required for the rotation operation of the sub endless chain mechanism, The rotation operation, that is, the operation to clear the clogging may not be performed quickly, or the rotation of the sub endless chain mechanism may cause the end between the end and the main endless chain mechanism. It means that you release all of the holding to have culms, many grain culm in the field there has been a problem that will be scattered.

[0005] It is a technical object of the present invention to provide a stock transfer apparatus which solves this problem.

[0006]

In order to achieve this technical object, the present invention provides a method for conveying a cereal stalk cut from one of a plurality of stalks to a feed chain or a cereal stalk vertical transfer device to the feed chain. A main endless chain mechanism; and a sub endless chain mechanism for transporting the grain stalks cut from the other of the plurality of rows. The end of the sub endless chain mechanism is appropriately spaced in the transport direction of the main endless chain mechanism. The endless chain is wound around the two guide rollers provided at the end of the sub-endless chain mechanism. Of the two guide rollers, only one of the guide rollers located on the near side with respect to the transport direction in the main endless chain mechanism is connected to the main endless chain mechanism. Backward and rotatably constructed in al away direction. "Is intended.

[0007]

In this configuration, when the grain stem is clogged at the portion where the sub endless chain mechanism joins with the main endless chain mechanism, the guide of the two guide rollers at the end of the sub endless chain mechanism is used. By retreating the roller, the clogged grain culm can be released, so that the clogged grain culm can be removed.

Therefore, according to the present invention, the entire sub endless chain mechanism need not be rotatable as in the prior art, so that the structure can be greatly simplified, and the size and weight can be reduced. In addition, since the one guide roller in which the clogging of the cereal stem is clogged retreats, the operation for clearing the clogging can be performed easily and quickly, and the cereal scattered in the field can be obtained. It has the effect of significantly reducing the number of culms.
