である。In particular, in the case of this invention, the drive sprocket mounted on the shaft at the rear end of the chain, that is, near the exhaust 7X transfer device, is constantly tensioned by a spring, and when maintenance is performed, the drive sprocket is rotated greatly together with the transmission case. 6 [Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention takes the following technical means. That is, a transmission case 5 whose input shaft is the drive shaft 4 of the haidan fan 3 installed in the dust removal section 2 of the threshing machine 1 is provided on the side of the chain 6, and a power take-off shaft 7 is extended from the transmission case 5 to the outside. A drive sprocket 8 is pivotally attached to the drive sprocket 8, and the drive sprocket 8 is provided with a pin 6 facing the starting end of the straw removal conveying device 9 so as to be transmittably engaged with the transmission case 5. This is a transmission device in a threshing machine equipped with a switching device i10 that switches a pinch chain 6 between a tensioned state and a non-tensioned state around a drive shaft 4 of a fan 3.

そして、殻稈は、脱穀処理を受けたのち挾やくチエン6
の終端部から排藁搬送装置9に受は継がれて後部のカッ
ター15に供給される。After the culm is threshed, it is processed into a chain 6.
The receiving straw is connected from the terminal end to the straw conveying device 9 and is supplied to the cutter 15 at the rear.
このような殻稈搬送過程において、挾やくチエン6は、
搬送する穀稈の層の厚さに応じて下方に押圧されてその
力が駆動スプロケット8を介して伝動ケース5を押し下
げることとなる。In such a process of transporting the culm, the chain 6 is
It is pressed downward depending on the thickness of the grain culm layer to be transported, and the force pushes down the transmission case 5 via the drive sprocket 8.
したがって、伝動ケース5は、駆動軸4を支点として張
圧ばね16に抗して下方に回転して挾やくチエン6と案
内杆14との間隔を殻稈量に適応した間隔に自動W8整
することができ、#2程量が変化しても円滑に搬送でき
る効果がある。Therefore, the transmission case 5 rotates downward against the tension spring 16 using the drive shaft 4 as a fulcrum, and automatically adjusts the distance between the chain 6 and the guide rod 14 to the distance W8 that is suitable for the amount of the culm. This has the effect of allowing smooth conveyance even if the amount changes as much as #2.
つぎに、伝動ケース5は、挾やくチエン6の終端部分、
あるいは、排藁搬送装置9の始端部と挾やくチエン6と
の間に藁屑が詰った場合には、第1図に示すように、操
作レバー17を操作して張圧ばね1Gの受座18を開放
して上方に下げて挾やくチエン6を開放する。Next, the transmission case 5 includes the terminal portion of the chain 6,
Alternatively, if straw waste is clogged between the starting end of the straw conveying device 9 and the clamping chain 6, as shown in FIG. 18 and lower it upward to open the chain 6.
したがって、詰り状態の藁屑は、取り除くことができる
。Therefore, the clogged straw waste can be removed.
