As described above, since the harvesting straw is concentrated in the supply depth conveying device, it is important to transfer the harvesting straw with the conveying force or the left bottom conveying device and the right bottom conveying device.

In particular, a large amount of rice (for example, hybrid rice or bio-ethanol rice) having a large yield has a long rice straw and a thick base. For this reason, when harvesting a large amount of rice with the conventional combine, the length of the straw is long and the thick rice straw is concentrated in the succession portion of the harvested rice straw to the supply depth conveying device, resulting in the same amount of rice straw as the conventional rice straw. Even the conveying volume becomes large. Therefore, in the succession part of the harvested rice straw with respect to a supply depth conveying apparatus, the conveying force with respect to the base of the harvested rice straw is liable to be insufficient. Then, as a result of not being able to sufficiently push the harvested rice straw into the rice straw inlet of the feed depth conveying device, the harvested rice straw is not pinched in the rice straw inlet of the feed depth conveying device, and comes out from the rice straw inlet of the feed depth conveying device. easy.

Due to the factors, there was a disadvantage incurring high cost.

When the description is added, for example, in the circular-shaped moving path located on the lateral side of the guide wheel body on the lower side, the outer shape of the casing is formed in an arc shape, along the outer shape of the arc shape, the straw stem in the standing position In order to form a guide portion for restricting the position of the lifting hook, a special processing technique such as drawing processing is required, thereby causing a high cost. In addition, also for the portion formed in the shape of an arc located on the lateral side of the guide wheel body on the upper side, similarly, a special processing technique is required, which has the disadvantage of causing high cost.

In addition, since the guide rail portion had to be integrally formed in the casing having a complex shape with a cover portion and a guide portion, the processing was cumbersome and the production was very laborious. In this way, there is a disadvantage in that it costs a lot of work, which causes high cost.
