And a supporting portion for supporting the drive sprocket side and a supporting portion for supporting the driven sprocket side are integrally connected via the upper chain rail, the lower chain rail, and a mounting frame for reinforcement, and the same feed is provided. The chain and upper and lower chain rails can be opened and closed laterally around the vertical axis, and the upper and lower chain rails are arranged diagonally with one side being lower than the other. It is intended to provide a threshing device for combined harvesters.

(E) Action / Effects The trimmed threshers for threshing are guided to the feed chain, and while the side of the threshing part is conveyed by the feed chain, the tip part is threshed. One side of the feed chain is a drive sprocket. While the other side is supported by the driven sprocket, the upper side of the feed chain, that is, the working side is supported by the upper chain rail, and the lower side,
That is, the non-working side is guided by the lower chain rail.

Then, the upper chain rail and the lower chain rail are integrally configured by a mounting frame for reinforcement, whereby the upper chain rail, the lower chain rail, the drive sprocket, and the driven sprocket are firmly configured. It is something.

Therefore, the noise of the feed chain is reduced and
This allows smooth cutting and threshing work.

Then, the upper chain rail and the lower chain rail are integrally connected by a reinforcing mounting frame, and the upper and lower chain rails and the feed chain supported by both chain rails are integrally united around the vertical shaft center. Since it can be opened to the side, maintenance of the handling barrel and the like in the handling room can be performed more easily than to the side of the threshing device.

At this time, since the upper and lower chain rails and the feed chain which are opened to the side are supported around the vertical axis, the opened state can be maintained without providing a separate supporting means. The inside of the handling cylinder can be maintained.

In addition, since the upper / lower chain rails and the feed chain are opened laterally around the vertical axis, the operator performing the opening operation can reduce the total weight of the upper / lower chain rails and the feed chain. The opening operation can be done easily without burdening.
