滑に移動させ難いものであった。Conventionally, there was a technique (for example, Japanese Utility Model Application Publication No. 50-97932) that used a culm support plate to close the space between the sugar transport device and the handling port, but the sugar transport device was removed and the tip was guided instead. When a guide plate for the shell culm is provided, there is a risk that the tips of the ears may get caught between the guide plate and the conveyance chain that transports the shell culm to the threshing section. The distance from the guide plate changes, making it difficult to move the tip smoothly along the guide surface of the guide plate.

ンの殻稈搬送装置を提供しようとするものである。The present invention solves the above-mentioned conventional drawbacks, and includes supporting the feed end of the conveyor chain facing the feed chain on the left side of the threshing section on the rotational fulcrum shaft of the entire reaping group, and also attaching a long and short culm on the back of the right pulling case. In the comparator 1, the feed start end of the conveyor chain is supported so as to be freely raised and lowered via an adjustment lever, and a culm guide plate connected to the back of the right-hand pulling case is extended to the upper surface of the handling port on the front side of the threshing section. A back culm guide plate is set up on the top of the chain guide of the chain,
A flexible culm support plate, one end of which is inserted between the shell culm guide plate and the handling port so as to be freely advanced and retractable, is connected to the back culm guide plate, and the sugar part conveying device is not used. The culm guide plate can properly guide the movement of the culm tip,
The structure of the reaping section can be easily simplified and downsized, and the displacement of the conveying chain when adjusting the handling depth with respect to the culm guide plate and the vertical movement of the reaping section about the rotation fulcrum shaft can be handled. By closing the space between the conveyor chain, the culm guide plate, and the handling port with the back culm guide plate and the culm support plate, the shape of the culm guide plate can be formed simply, and at the same time, the culm guide A combine harvester in which the plate and the long/short culm adjustment lever can be easily supported by a right-hand-pulling case, drastically reducing desugarization, cutting of ears, etc. compared to the conventional case, and significantly improving the transfer function using only the conveying chain. The present invention aims to provide a shell culm conveying device.

ある。As shown in the above embodiments, the present invention has the feeding end portion of the conveying chain 31 facing the feed chain 5 on the left side of the threshing section 4 supported by the rotation fulcrum shaft 8 of the entire reaping section T, and the rear side of the right pulling case 25. A shell culm guide plate 30 supports the feed start end of the conveyance chain 31 so as to be able to rise and fall via a long/short culm adjustment lever 33, and is connected to the back of the right-hand lifting case 25.
In the combine in which the chain guide 36 of the conveying chain 31 is extended to the upper surface of the handling port 35 on the front side of the threshing section 4,
A back culm guide plate 37 is erected on the upper surface, and a flexible culm support plate 38 is connected to the back culm guide plate 37, one end of which is inserted into the opening between the shell culm guide plate 30 and the handling port 35 so as to be able to move forward and backward. With this structure, the tip of the culm can be properly guided by the culm guide plate 30 without using a conventional panicle conveying device, and the structure and size of the reaping section 7 can be easily simplified and downsized. At the same time, the conveyance chain 31 and the culm guide plate are adjusted in response to the displacement of the conveyance chain 31 with respect to the culm guide plate 30 when adjusting the handling depth and the vertical movement of the reaping section 7 about the rotation fulcrum shaft 8. 30 and the handling opening 35 by the back culm guide plate 3T and the culm support plate 38, the shape of the shell culm guide plate 30 can be formed simply, and at the same time, the shell culm guide plate 30 and the long and short sides can be easily formed. The culm adjustment lever 33 can be easily pulled to the right and supported by the case 25, and compared to the conventional method, desugarization, culm cutting, etc. can be drastically reduced, and the transfer function using only the conveyance chain 31 can be significantly improved. This has practical effects.
