Next, the essential part of the grain culm transportation of the present invention will be described in detail with reference to FIGS.

The grain culm conveying device of the present invention is for a 5-row combine.

That is, the weeding boards 2 and the raising devices A are arranged so that the narrow outer side of the transport path on the non-crop side has one line, the central part has two lines, and the other end has two lines. .

Then, the lower right side transport device 11 and the lower left side transport device 12 are formed in a “C” shape, and are joined at a substantially rear central portion. B and its confluence.

Further, the central lower carrying device 13 is formed in a slightly smaller "C" shape with respect to the left lower carrying device 12, and the lower central carrying device 13 joins at the rear substantially central part. C is the junction.

Therefore, the outer one grain culm is conveyed toward the center of the machine body, and merges with the two center grain culms of the machine body, that is, the merging section B to form three lines, and is further conveyed to the other two lineages. It is possible to join the rice culm at the central portion, that is, at the joining portion C.

In this manner, the two grain culms in the central portion are conveyed straight rearward, and the two right ridges are moved to the central portion along a stable transportation route.

Further, the other one article is a slightly narrower conveyance path, but since it is one article, it is brought close to the central portion in a stable state.

In this way, the two routes in the central part are straight rearward, and the other two routes and one route are moved toward the center so that the grains can be transported smoothly, and the number of lines at the time of merging can be reduced. Since the difference was small and the distance was short, culm disturbance and shattering of ears were reduced.

In addition, since the transportation is smooth, it can be widely applied especially during high-speed work and also in soft culm and fall culm.

After that, the stock yuan section transfers from the merging section B to the stock yuan vertical conveying device.
It is handed over to 22.

Further, since the upper transfer devices 40, 41, 42 are arranged so as to be polymerized immediately above the respective lower transfer devices 11, 12, 13 so that the tips of the grain stems follow the same transfer path as the root part, It is taken over by the vertical tip conveying device 21.

(F) Effect of the Invention Since the present invention is configured as described above, it has the following effects.

First, in the technique shown in FIG. 9 of JP-A-60-237915, a right side single-row lower transporting device is arranged at the right end, and a left end is a left-side two-row lower transporting device. Is configured as a central two-row lower conveying device, and the left and right sides are completely reversed.

In this way, even if the left and right sections are configured in reverse, the operator's seat is located on the right side of the machine and the feed chain of the threshing machine is installed for the machine because of the ergonomically right-handed operator. It is arranged on the left side of, and most of the work is carried out by cutting left-handedly, so the following problems were encountered in the prior art.

That is, it is necessary to surely catch the outermost one line on the uncut side between the grass plates 2 and 2 in the right-side two-row lower conveying device 11.
Be careful with the alignment.

Further, although the first and second lines are to be joined first, this joining part is joined at a position distant from the feed chain, and the unstable transport portion after joining is lengthened. As a result, culm drop and culm overflow are likely to occur.

The present invention has solved the above problems.

Secondly, by transporting the two central grain culms straight rearward and collecting the left and right grain culms almost in the center, the grain culms can be transported smoothly and the number of grain lines at the time of merging can be reduced. Because the difference is small and the distance is short,
Disturbance of culms and shattering of ears were reduced.

Thirdly, since the conveyance is smooth, the combine can be widely applied, especially during high-speed work, and also in soft culm and fall culm.
