[Problems to be Solved by the Invention] In the invention, as shown at the beginning, the right and left stock carrier chains are arranged in the shape of a square open at the start end side in plan view, and the stock base side of the harvested grain culm is arranged. Postpone,
This is a multi-row cutting that passes from the junction on the terminal side to the feed chain in the threshing section via the vertical transport chain, and transfers the harvested culm from the junction on the terminal side to the start end of the vertical transport chain. It was devised for the purpose of preventing dropping of the grain stalk and disturbance of the transport posture by not being affected by the increase or decrease of the grain stalk amount, so that unhandled etc. in the threshing part does not occur. Things.

[0004]

Therefore, in order to achieve the above-mentioned object, the present invention arranges the left and right stock transfer chains in a C-shape which is open at the start end side in a plan view, so that the cut stock side of the cut culm is rearward. Send
In the multi-row cutting combine which passes the feed chain of the threshing unit via the vertical conveying chain from the junction on the terminal side, the interval between the junctions on the terminal end side of the left and right stock transfer chains is used for high and low speed operation of traveling speed. It is configured to be able to adjust the width in conjunction with it.

[0005]

With the above construction, the culms harvested by the cutting blade while weeding are gathered while being sent back by the right and left stock carrier chains, merged at the junction on the terminal side, and then joined vertically. Threshing is carried out in the threshing section by passing the feed chain to the starting end side and nipping and feeding the feed chain. In the harvesting and threshing work, when the running speed of the machine is shifted to a high speed side, the threshing operation is interlocked with this operation. Thus, the above-mentioned interval is widened, and when the shift operation is performed to the low speed side, the interval is adjusted to be narrow. In other words, the interval increases when the amount of harvested culm increases by shifting to a high-speed side, and the interval decreases when the speed decreases and the amount of cereal culm decreases, and the interval becomes appropriate in response to the increase or decrease in the amount of cereal culm. It is adjusted so that it is smoothly transferred from the end to the start of the vertical transport chain.
