摘要
An automatic drainage device for controlling an amount of outflow from a paddy is provided to make smooth adjustment of the amount of outflow and a level. An automatic drainage device for controlling an amount of outflow from a paddy comprises a drainage device body(10) buried in a bank(B) of the paddy. A drainage pipe(20) passes through the drainage device body so as to communicate the inside with the outside of the paddy. An elbow inflow pipe(30) is rotatably coupled to the drainage pipe(20), and includes an inlet(32) through which water flows and a connector(34) coupled to the drainage pipe such that the inlet and the connector are disposed at a predetermined angle. A drive unit(40) rotates the elbow inflow pipe. A control unit(50) controls the drive unit. A height of the inlet is adjusted so as to be lower or higher than the level of the paddy according to a rotating angle of the elbow inflow pipe.
