うになっており、これらの殻稈搬送装置の全体構造が比
較的複雑で、その製造コストが高くなる嫌いがあった。In general, in combine harvesters for full-surface multi-row mowing, after the culm cut by the cutting blade behind the dividing rod is raked by multiple raking devices, the lower and upper parts of the culm are transferred to a lower conveyor. The machine is transported to the rear of the machine while being supported by an upper transport device, but in conventional combines of this type, for example, multiple shell culm passages were formed in parallel along the front and rear direction of the machine, so they were guided to the rear of the machine. The ground culm is once joined to the left side of the front side of the threshing machine using a cross-feeding device, and then the merged husk culm is conveyed to the starting end of the foot chain by a vertical conveyance device, and this culm is transferred to the foot chain. At the same time, it is inserted into the handling chamber from the handling port of the threshing machine and threshed using the handling barrel equipped on the threshing machine. The overall structure is relatively complex and the manufacturing cost is high.

特に、横送り装置を付設して各殻稈通路からの殻稈を合
流させることは上述した構造の複雑化と製造コストの高
騰とを余儀無くするものであった。In particular, adding a cross-feeding device to join the culms from each culm passageway inevitably complicates the structure and increases manufacturing costs as described above.

また長短稈調節可能な搬送体を殻稈通路の終端に臨ませ
るとき、搬送体が長短稈調節によって変位するので、殻

ド等の取付は構造が煩雑となっていた。In addition, when the conveyor body whose length can be adjusted is placed facing the end of the culm passage, the conveyor body is displaced by adjusting the length and shortness of the culm, so the conveyor body approaches and separates from the end of the culm passage, and the culm transfer operation is carried out. Therefore, it is necessary to prevent the culm from falling off and becoming clogged, and the structure of installing a culm guide, etc. to prevent this has become complicated.

In the combine harvester in which the V-shaped shell culm passages are merged at the rear side, and the starting end of the conveying body whose length and length can be adjusted is faced behind the merging part, the lower part forming the - ten thousand shell culm passages. The terminal end portion of the conveying chamber is bent, and the terminal end portion of the lower conveying chamber is arranged substantially parallel to the conveying body, so that the culm is inherited from the terminal bent portion of the lower conveying chamber to the conveying body. This configuration allows the shell culm passage to have a simple structure and be manufactured at low cost, and even if the conveyor moves by adjusting the length or shortness of the culm, the shell culm from the lower conveyor chain can be properly inherited, and it is possible to avoid complicated The purpose of the present invention is to provide a culm conveying device for a combine harvester that can prevent culm transfer errors and transport disturbances without providing a culm guide, and can functionally feed culms with a small number of parts. be.
