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.

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.

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.
