发明名称 Drainage tile flow regulator
摘要 The tile flow regulator disclosed is used for regulating the level of water in the fields of an agricultural operation according to seasonal needs by a mechanism for adjusting the outflow of water from the tile line. The regulator includes a housing through which water from the tile line is directed and in which a partition with at least one aperture is positioned. At least one vertically movable gate is associated each aperture and with a motor and gear assembly such that, upon actuation of the motor by a 12-month calendar, said gate(s) move to either open or close the aperture. If two apertures are included, the regulator can be fully open (both apertures open), fully closed (both apertures closed), or partially open (bottom aperture open, top one closed) to achieve the desired moisture level.
