延設してあり、その最後部の１個所で駆動モータＣにて
駆動するようにした構造となっていた。In other words, the screw conveyor device used in the conventional screw conveyor system is as shown in Fig. 1, in which a screw b is connected and extended over the entire length of the transport pipe α, and at one point at the rearmost part of the screw It had a structure in which it was driven by a drive motor C.
このため排土口ｄに近い最後部の軸及び羽根さらに駆動
モータｃｆ保持する保持部にかかるトルクが大きくなり
、強度上１寸法上あまり輸送用Ｍを大きくできなかった
。For this reason, the torque applied to the rearmost shaft and vane near the soil discharge port d, as well as the holding part that holds the drive motor cf, becomes large, and the transport M cannot be made very large due to one dimension of strength.
