[0002] As a major agricultural country in the world, my country has a very rich annual crop output. At the same time, my country is also vigorously supporting the development of agriculture. In order to ensure that crops can grow healthily and quickly during planting, irrigation devices are generally installed at designated locations in the farmland. This can greatly increase the irrigation efficiency of the farmland and greatly reduce the labor of the planting personnel. However, the existing farmland irrigation devices still have some shortcomings. For example, when irrigating with water sources, the water is not sprayed evenly, resulting in some locations being submerged in crops, but other locations lacking water. At the same time, the current irrigation devices cannot perform low-cost automatic irrigation and require some precise flow equipment to achieve the function of automatic irrigation. This method not only greatly increases the cost of the irrigation device, but also makes the operation complicated. For this reason, we propose an automatic quantitative water-saving irrigation device for farmland. Utility Model Content
