The tip auxiliary conveyance device 13 is set higher than the horizontal conveyance mechanism 17.

In addition, on the front side of the horizontal conveyance mechanism 17, a rotary packer 18 that acts on the culm of the central path and a stock auxiliary conveyance device 19 consisting of a rubber belt with protrusions share a common drive shaft and are arranged in two stages, upper and lower. A rotary packer 20 and a stock auxiliary conveyance device 21 are installed horizontally and have the same structure to act on the culm of the most cut side path C, and above these, a tip consisting of a chain with a protrusion is installed. An auxiliary horizontal conveyance device 22 is installed horizontally.

A joint 24 is erected on the divider support rod 23 located between the main, uncut side and center pulling devices 9a and 8b, and a joint 24 is provided on the left and right sides of this wing 24, facing the tip conveying device 12. A shell culm guide wing 25 and a shell culm guide wing 26 facing the rotary packer 18 and stock auxiliary conveyance device 19 are provided in a protruding manner.

Furthermore, a culm guide rod 27 that faces the tip auxiliary conveyance device 13 extends in a cantilevered manner from the back side of the central lifting device 8b.

In addition, below the backward feeding action section 16b of the ear tip locking and conveying device 16, there is provided a stock gripping and conveying device 28 which has a handling depth adjustment function and can swing up and down about the front horizontal axis fulcrum Q. At the same time, a relay stock head conveyance device 29 is provided in a fixed position at the lower part of the terminal end side of the ear tip locking conveyance device 16.

In the present invention, in particular, the three-stage conveying device 11 described above is
, 12, 13 are configured as follows.

In other words, the upper and middle conveying devices 13 and 12 are provided so as to extend far forward than the reaping device 9, the lower conveying device 11 is provided close to the top of the reaping device 9, and the upper conveying device 13 is located in the middle and lower tier. It is arranged closer to the right side than the conveying device 12.11.

The shell culm conveying device of the present invention is constructed as described above, and its conveying function will be explained next.

The culms of the uncut side and the central pulling reaping paths a and b are joined together by conveying devices 11, 12, 13, rotary packer 18, and conveying device 19, and are pulled rearward and harvested.

In addition, the culms in the already-cut side path C are pulled rearward and cut by the rotary packer 20 and the tip auxiliary conveyance device 21, and then are moved by the lateral feeding action of the stock root tip conveyance devices 14, 15 and the tip locking conveyance device 16. A lateral conveyance mechanism 17 consisting of a section 16a,
It is then supported by the tip auxiliary lateral conveyance device 22, and is laterally fed to the left, and laterally merges into the merging portion of the two culms.

Then, the merged three culms are transferred to the rear feed action section of the left and right stock head conveying devices 11.14 and the left and right ear tip conveying devices 1.
After being sent rearward by the backward feeding section 2.15, the backward feeding section 16b of the tip locking and conveying device 16, and the tip auxiliary conveying device 13, the tip of the tip locking and conveying device 16 continues to be sent.
At the end of the conveyance, the tip of the culm is turned sideways into the interior of the machine, and the stock head is transferred to the relay conveyor 29. Then, the stock head is fed to the feed chain 19 in this sideways posture.

In this case, of the three upper and lower conveying devices 13, 12, and 11, the upper conveying device 13 is closer to the right side than the middle conveying device 12. It acts not only on the sugar part of the shell culm in the adjacent route, but also on the tip side parts of the shell culm in both routes a and b, which have not yet been harvested. Even when the spacing between the plant base positions of the planted culms in paths a and b is relatively wide from side to side, the harvesting device 9 can easily merge the tip side portions and keep the plant base portion from falling down. It can lead to.

In addition, since the upper middle conveying devices 13 and 12 protrude further forward than the reaping device 9, the introduction of the following culms is reduced when the volume of the planted culm is small or near a separate road. Even if the culm falls forward immediately after reaping, the front spillage is prevented by the retraction action of both the upper and middle transport devices 13 and 12 or the retraction action of the middle transport device 12 (when the culm is short).

Since the combine harvester culm conveying device according to the present invention is constructed and operates as described above, the husk culms of the two adjacent pulling reaping paths a and b can be smoothly and smoothly merged from the tip side portions and forward. It is now possible to pull it backwards and transport it without spilling.
