などよりなる刈取後処理部とによって構成されている。[Prior Art] Conventionally, this type of reaping unit has been used to reap crops using a raising device that raises the erect grain culm to a standing position, a first reaping device that cuts the stock base of the raised grain culm, and a first reaping device. A pre-harvesting processing unit includes a holding and conveying device that holds and transports the harvested grain culm in a standing position; a second reaping device that cuts the side of the ear of the harvested grain culm; The grain culm is composed of an auger that collects and transports the grain, and a post-harvesting processing section that includes a feed conveyor that receives the collected grain culm from the auger, lifts it up, transports it, and feeds it to a threshing section.

後方へ抜けぬくくなり、溜りの原因となっていた。[0003]The cutting length can be arbitrarily adjusted by vertically moving a second reaping device that cuts the rear upper part of the grain culm tip side relative to the first reaping device that cuts the stock side of the grain culm. This technique is also known. However, in such conventional technology, for example, when the second reaping device is raised, the cutting length with respect to the first reaping device becomes longer, but the distance between the bottom plate of the auger (receiving trough) and the ground remains constant and does not change. This made it difficult for the cut straw to pass through backwards, causing a pool.

In the input type combine harvester, which is configured to be able to be raised and lowered, the reaping section A includes a raising device 7 that raises the erect grain culm to a standing position.
, a first reaping device 8 for cutting off the stock base of the raised grain culm, a holding and conveying device 9 for holding and conveying the grain culm harvested by the first reaping device 8 in a standing position, and the like.
and a second reaping device 10 that cuts the side part of the ear tip of the reaped grain culm.
An auger 11 that receives the harvested grain culm and collects it toward the center side in the lateral direction, a feed conveyor 13 that receives the collected grain culm from the auger 11, lifts and conveys it, and supplies it to the threshing section B. The post-reaping processing section 5 is configured to be movable vertically and fixedly fixed to the pre-reaping section 4 concentrically with the fulcrum axis of the reaping section A. It is characterized by this.

、切断ワラが長くなっても後方への排出が良好となる。[Operation] The stock side of the standing grain culm that has been raised to a standing position by the pulling device is cut by the first reaping device installed at the lower front position, and the cut grain culm in each row is transferred to the clamping and conveying device. Transport it by holding it backwards in a standing position. Then, at the terminal end of the clamping and conveying device where the grain culms of each row join together, the side portions of their ears are cut off by a second reaping device. The cut side part of the ear is received on an auger, fed horizontally, lifted up and conveyed by a feed conveyor, and fed into a threshing section. The cut straw on the stock side passes backward through the gap between the auger bottom plate and the ground. If the grain culm is a long culm, the cutting height is adjusted by raising the second reaping device and changing the distance from the first reaping device, but at this time, the height of the auger bottom plate from the ground increases. Therefore, even if the cut straw becomes long, it can be easily discharged to the rear.

果的かつ能率的になし得られるものである。Therefore, according to the present invention, even if the cut straw becomes longer due to raising the second reaping device, the distance between the auger bottom plate and the ground becomes larger, so that the cut straw becomes longer. It is easy to pass through to the rear, and the muddy soil and stumps can be discharged well, especially when harvesting fallen crops in wet fields. As a result, the two-step mowing work of grain culms can be carried out effectively and efficiently.
