It is supported and installed on the reaping side, that is, on the side of the reaping conveyance section that moves up and down relative to the combine traveling body, so if the height of the reaping conveyance section above the ground is changed, the height relative to the foot chain on the traveling machine side will change. There is a problem that the position changes and the transfer of the culm from the receiving and conveying chain 7 to the foot chain is not carried out in a stable state.

In addition, when the conveyed culm is a short culm, the lower conveying cheno is tilted so that its terminal end approaches the receiving conveying chê 7, and the depth of the culm supply to the threshing section is adjusted to be deep. However, in the conventional technology, the transfer and conveyance chain 7 is provided parallel to the axial direction of the link pin of the foot chain.
Moreover, since the configuration is such that a transmission case for driving the inheritance conveyance check 7 is interposed between the overlapping portion of the inheritance conveyance check 7 and the terminal end of the lower conveyance check, the terminal end of the lower conveyance check is close to the inheritance conveyance check 7. Therefore, when adjusting the short culm, it is not possible to make the handling depth sufficiently deep, resulting in unhandled parts, and furthermore, it is difficult to transfer the shell culm from the lower conveyance cheno to the transfer conveyance ch 7. There is also the problem that the grip change does not go well and the posture tends to be distorted.

Therefore, the present invention is capable of conveying and supplying the husks from the reaping side from the lower conveyance cheno to the transfer conveyance chê 7 in a good clamping posture, reliably, and smoothly. This was implemented with the aim of providing a shell culm transport device that can transport shell culms to a suitable handling depth.

That is, in the present invention, the receiving and conveying check 7 installed in communication with the starting end of the foot chain is tilted with respect to the axial direction of the link pin of the foot chain when viewed from the front, is supported on the starting end side of the foot chain, and is driven from the foot chain side. The above-mentioned object is achieved by configuring the terminal end of the lower conveyance chino so as to be able to approach the lower side of the support plate in the chain of the transfer conveyance chino. be.
