Description

[Detailed description of the invention] This invention relates to a guide mechanism for the upper conveying body of a combine harvester that reaps and threshes husks while traveling.In particular, the upper part of the husks that have been cut in the reaping section is transferred to the threshing section via an upper conveying chino. This invention relates to a guide mechanism for the upper conveying body of a combine harvester for multi-row cutting, which is conveyed to the shell culm supply port of the harvester.

one! In the Yoko multi-row harvesting combine harvester, the upper part of the culm cut in the reaping section is transported by left and right upper transport chenos located above the machine body, and is also transported separately by these left and right upper transport chenos. After the upper part of the husk is collected at an appropriate position, the receiver is passed to the feed chain and transported to the husk supply port of the threshing section.

However, in this case, at the collection point of the culms that have been flowing in two directions by the left and right upper conveyance chenos, the tips of the husks are disturbed or delayed due to irregularities in the length of the culms, which impedes the threshing operation in the threshing section. There was a problem.

On the other hand, such combine harvesters are equipped with guides to ensure the transportation and gathering of the upper part of the culm, but when the combine enters a field with culm vegetation, it must not be placed in any corner of the field. In the field, the shell culm is harvested by hand in an area slightly larger than the area of the combine harvester, and the combine harvester is placed on a separate road, and the shell culm harvested in the corner of the field is usually threshed by hand. Therefore, there is a problem in that the guide obstructs the operation of supplying the husk to the threshing section during cutting.

In order to deal with such problems, it has been proposed that the guide is formed of a plate-like body that is detachable from the machine body, and the position of the guide is selectively changed during manual threshing and reaping threshing. However, (Actual Publication No. 48-3720),
In this type of product, the operation of changing the position of the guide is troublesome, and since the guide is tilted in the normal position at the time of harvesting and removal, the length of the tip of the culm may not be constant. There is no problem if the culm is a mixture of long and short husks, but the tips of the husks will vary up and down, so in such cases it is difficult to feed the husks to the threshing unit with the tips aligned. There is a problem in that the handling depth is different during reaping threshing and manual threshing because the angle at which the guide is attached to the handling drum is different.

The present invention was made to solve the above problems, and provides an upper conveyance guide mechanism in a combine harvester that not only makes the threshing operation smooth but also makes the feeding of husk to the threshing section efficient when threshing is done by hand. The purpose is to provide.

Next, to explain the drawings of one embodiment of the combine harvester according to the present invention, in FIG. 1 showing a side view and FIG. 2 showing a plan view, a grass dividing plate 2.

Therefore, during reaping and threshing, the grass dividing plates 2゜2', 2''
The upper part of the culm, a/..., which has been sorted by the reaping unit 3 and whose stock base has been harvested by the reaping section 3, flows in two directions by the left and right upper conveyor chenographs 12 and 13, and then is transferred to the left upper conveyor chenograph 12. After being concentrated in the vicinity of the opposing position between the terminal end of the upper right conveyance cheno 13 and the upper right conveyance chino 13, the two guide parts 14a and 14b of the upper conveyance guide 14 are conveyed to the foot chain 6. The bent part 14' of the culm is located facing the left and right gathering positions of the upper part of the culm, and the other guide part 14b is arranged at a position along the right upper conveyance chain 13 that then conveys the gathered culm. As a result, the culm to be transported is adjusted without causing unevenness at the tip of the tip, regardless of the length of the culm, and therefore, the disturbance of the culm conveyance due to the long and short culms and the damage to the tip of the culm are avoided. The husk is fed to the culm supply lower without any delay and is smoothly threshed in the threshing section 8.
