[0002]

2. Description of the Related Art Generally, a conveyor device of this type is actually developed.
As disclosed in 0-161931, etc., the screw main body is mounted over the entire length of the inside of the tubular body, and an inlet for grain such as paddy is provided at one end of the tubular body, and an outlet is provided at the other end. It is known that a transport unit is provided to form a plurality of transport units, and the plurality of transport units are connected so that one discharge port communicates with the other introduction port. In order to drive the screw main body of the conveyor unit, this conveyor device is provided with a drive motor for each individual conveyor unit so that each screw main body is rotationally driven. This
In the conveyor device , since one drive motor is required for each transport unit, the drive mechanism of the conveyor device becomes complicated, and the electric wiring structure connected to the drive motor becomes complicated, resulting in an increase in product cost. There was a problem. In addition, the drive motor attached to each individual transport unit increases the overall weight of the conveyor device and also makes each transport unit heavy, which makes handling inconvenient. Especially, this type of conveyor device is hung at a high place. Since it is used by being lowered, there is a problem that the efficiency of the installation work is lowered and the connecting work of the respective transport units becomes complicated.

Therefore, in Japanese Utility Model Laid-Open No. 60-17644.
