The invention discloses a self-adaptive water-saving irrigation and drainage device for farmland. The device comprises a supporting plate fixed in the farmland and further comprises a conical friction wheel, wherein a partition plate used for separating the farmland from a river channel is fixedly connected to the upper surface of the supporting plate, a drainage port and an irrigation port are formed in the surface of the partition plate, a first through hole is formed in the surface of a sliding block, a rotating shaft is rotationally connected to the inner wall of the first through hole in a fixed-axis mode, an outer spline is arranged on the surface of the rotating shaft, an inner spline sleeve is meshed with the surface of the outer spline, a friction wheel is fixedly connected to the right side of the inner spline sleeve, and a second through hole allowing the rotating shaft to penetrate through is formed in the surface of the friction wheel. The device has the effects that water in the farmland and water in an irrigation canal are subjected to water circulation to provide nutrients for rice and drainage can be accelerated on rainy days, and the problems that in the rice planting process in the farmland, sufficient nutrients cannot be provided for the rice through water circulation, and the rice cannot be prevented from being drowned due to the fact that the water level line in the farmland is increased on rainy days are solved.
本发明公开了一种自适应农田用节水灌溉排涝装置，包括固定在农田内的支撑板，还包括有锥形摩擦轮，支撑板的上表面固定连接有用于隔开农田和河道的隔板，隔板的表面开设有排涝口和灌溉口，滑块的表面开设有通孔一，通孔一的内壁定轴转动连接有转轴，转轴的表面开设有外花键，外花键的表面啮合有内花键套，内花键套的右侧固定连接有摩擦轮，摩擦轮的表面开设有用于转轴穿过的通孔二，本发明具备了将农田中的水与灌溉渠中的水进行水循环为水稻提供养分以及在雨天可以加速排涝的效果，解决了农田中水稻种植过程中，不能做到水循环为水稻提供充足的养分，以及不能预防在雨天水稻因农田中水位线的提高而被淹死的问题。
