Irrigation gate for rice fields, characterized in that the bracket (4) is equipped with a motor (5), a connecting rod mechanism (6), and a travel switch (7). The connecting rod mechanism (6) consists of a first connecting rod (61) and a second connecting rod (62). The first connecting rod (61) has one end mounted on the output shaft of the motor (5), while the second connecting rod (62) is pivotally connected at its ends to the first connecting rod (61) and the force arm (8). The motor (5) and the travel switch (7) are fixed to the bracket 4. The lower surface of the travel switch (7) features a horizontal position stop switch (71), and the inner surface of the travel switch (7) is equipped with a vertical position stop switch (72).

Shut Gate: Activate the motor, which rotates the three-bar linkage mechanism. The linkage drives the power arm to lift the free end of the gate above the water level. When the free end of the gate is horizontal, the power arm contacts the horizontal position of the stroke switch, stopping the switch, and the motor ceases operation. The free end of the gate remains above the water level stationary. At this point, the gate is closed, preventing water from flowing from the corrugated hose to the rigid conduit, and thus from reaching the next field.

3. Open the gate: Start the motor, which drives the linkage mechanism to continue rotating in the same direction. The free end of the linkage mechanism, connected to the arm of the gate, lowers the gate. The free end of the gate is perpendicular to the ground. At this point, the arm contacts the vertical position of the travel switch, stopping the motor; the free end of the gate remains submerged under the water surface without moving. At this stage, the gate is open, allowing the water channel to flow into the rigid conduit and then into the next paddy field.
