Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, and in particular to a water-saving device for controlling farmland irrigation. Background Technology

[0002] In farmland irrigation systems, valves, as core components controlling water flow and regulating flow, are crucial for achieving precision irrigation and improving water-saving efficiency. A farmland irrigation control water-saving device needs to ensure stable water flow regulation during irrigation through reliable valve components, reduce water waste, meet the water requirements of different crop growth stages, and contribute to the efficient and sustainable development of agricultural production.

[0003] Existing water-saving irrigation control devices for farmland primarily consist of simple valves, piping systems, and basic controllers. Their technical principle is mainly based on the simple collection of information such as soil moisture and weather conditions. By setting pre-defined irrigation thresholds, when soil moisture falls below the set value or weather conditions meet irrigation requirements, the controller issues a command to open the valve for irrigation. The valve closes after the set duration or humidity condition is met. Some devices employ basic electromagnetic valve structures, using an energized electromagnetic coil to generate magnetic force, driving the valve core to control the flow of water. Overall, these devices attempt to achieve a certain degree of water conservation and irrigation management through basic control of irrigation timing and water flow.

[0004] Existing farmland irrigation control water-saving devices have significant shortcomings in irrigation. They are difficult to finely regulate according to the actual water demand differences in different farmland areas and cannot be accurately adapted. When facing different crop types and different growth stages, the internal filtration and seepage structures of some support covers may not be effective, resulting in a lack of optimal allocation of water resources. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water-saving device for farmland irrigation control, which aims to improve the difficulty in adjusting according to the actual water demand differences in different farmland areas. This is because the valve control is mostly a relatively crude on / off operation, and the pipeline layout and water flow distribution lack a precise dynamic adjustment mechanism, resulting in a lack of precise adaptation.

[0016] 2. In this utility model, the bolt two is rotated by turning the handle. The bolt two rotates inside the fixed housing one and the fixed housing two. The size of the water pipe can be changed by turning the handle. The fixed housing one moves and drives the rotating shaft three to rotate. The rotating shaft three rotates in a fixed position inside the fixed housing. The fixed housing two moves and drives the filter plate to move. The filter plate filters and intercepts impurities and harmful substances that appear during the water delivery process. The movement of the filter plate drives the sealing strip to move. The sealing strip prevents impurities from leaking during the water delivery process. Attached Figure Description
