Description

  The present invention relates to a combine that harvests uncut cereal grains in a field using a pre-harvest processing device and threshs the harvested cereal grains using a threshing device. After sorting, the first sort (grain) is taken out by the first conveyor through the swing sorter, and the second sort (mixture of grain and sawdust) is taken by the second conveyor through the swing sorter. It is related with the combine comprised so that it might be taken out by.

  Conventionally, a combine harvests a traveling machine body equipped with an engine, a traveling crawler as a left and right traveling unit that supports the traveling machine body, a driving unit having a steering handle and a driving seat, and an uncut grain culm in a field. A pre-cutting processing device and a threshing device for threshing the harvested cereals are configured to continuously shave and thresh uncut cereals in the field and collect grains (for example, Patent Document 1).

In this case, the conventional combine is configured such that the second sorted matter taken out by the second conveyor from the swing sorter is returned to the swing sorter via the second reduction cylinder.

  As shown in Patent Document 1 or Patent Document 2, the prior art has a first cereal cylinder that takes out the first selection from the first conveyor below the swinging sorter on the side of the threshing device. Has been. In addition, the second reduction cylinder connected to the feed end side of the second conveyor arranged behind the first conveyor on the lower side of the rear part of the swing sorter is the threshing on the side where the first cereal cylinder is arranged It is arrange | positioned so that it may extend to the front upper direction from the back of the first cereal cylinder in the side of an apparatus. By the second reducing cylinder, the second sorted product was returned to the upper surface side of the front part of the swing sorter. As a result, since the first cereal cylinder and the second reduction cylinder are arranged so as to cross at the side of the swing sorter, the size of the combine (threshing device) in the left-right width direction is limited. However, there is a problem that the width dimension in the left-right direction of the swing sorter is limited and becomes smaller, and the sorting processing ability of the swing sorter cannot be improved.

  Moreover, the threshing of the harvested cereal meal supplied to the threshing device is almost completed in the first half of the handling cylinder. As a result, a large amount of degranulated material such as shed grains falls from the front half of the handling cylinder to the lower rotation side of the handling cylinder in the upper surface on the front side of the swing sorter. Therefore, when the second reduction cylinder is placed on the lower rotation side of the barrel of the threshing device opposite to the side where the feed chain is installed, it is not limited to the feed chain, Although the second reduction cylinder can be placed close to each other, returning the second sorted product to the upper surface on the front side of the rocking sorter not only reduces the separation processing capacity of the shattered material in the rocking sorter, but also swings. There is a problem that the sorting ability of the second sort in the sorter is reduced. In addition, when the second sorter is returned to the upper surface on the rear side of the swing sorter, the second sorter is circulated without being sorted, so that a large amount of the second sorter is generated. It goes without saying that there is.

  In addition, since the second emitter cannot be replaced with a second emitter with different specifications, the type of cereal or the threshing status of the second sort (the amount of stings or scraps in the second sort) is considered. As a result, there is a problem that the processing contents of the second selected matter in the second emitter cannot be easily changed.
