伝動支持装置を提供できる効果を有するものである。As described above, the present invention relates to a grain stalk supply / transportation device 2 provided in a combine pre-cutting device 1.
, A transfer transmission shaft 5 having a rotating wheel 4 around which the transfer endless belt 3 is wound is attached to the shaft end, and an intermediate transmission shaft 6 provided on the same transmission case 7 as bearings. A transmission gear 8 mounted on the transmission shaft 6 is always engaged with a transfer gear 9 provided on the transfer transmission shaft 5, and the transmission case 7 is provided with a grain culm transfer passage a of the pre-cutting device 1. A transmission coupling device which is provided so as to be freely engaged with and disengaged from a transmission gear box 10 on the side of the drive shaft 11 and which is mounted on the transmission gear box 10 and the intermediate transmission shaft 6 of the transmission case 7. Since the sliding in the axial direction is configured to be freely disengageable and disengageable via the 12, the transmission gear 9 and the conveying gear 9 can be moved even when the conveying load is applied to the grain culm feeding and conveying apparatus. A durable transmission support device with no change in the engagement depth and no wear And it has a possible effect.
