An irrigation gate for a salt farm is provided to inject or discharge brine to or from a salt farm smoothly and shortly by operating a rubber tube using a handle, and not to do harm to the human body, to have good sanitation and to take practical and economical effects by using a rubber tube made of natural rubber. An irrigation gate for a salt farm is installed on a bank of a salt farm to let brine flow in or out from a salt farm, and formed by putting a cover(9) on an open top of an irrigation gate body, forming elliptical perforations(2) on the front and rear of the irrigation gate body, attaching a tube insert(3) to the inside of the body and fixing a metallic tube support to the bottom of the center of the body with bolts(6), forming a projection on the end of the tube support and supporting a rubber tube(7) and forming a handle(8) at the top of the tube support to be projected to the upper part of the cover, forming a cutting part(9a) on one side of the cover and forming a handle fixing groove(9b) on the end of the cutting part, and forming drain outlets(10) on two sides of the body. The irrigation gate enables to make brine flow in or out from a salt farm by pulling the handle of the body forward and descending the tube support fitted with the rubber tube to make the rubber tube level in a straight line, thereby to simplify the inflow and outflow of brine to and from the rubber tube, and to stop the flow of brine by pulling back the handle and ascending the tube support to make the rubber tube pressed to the tube support. |
