Description

Technical Field

[0001] This utility model belongs to the field of farmland irrigation technology, and in particular relates to a farmland water-saving irrigation device with automatic water supply and drainage control. Background Technology

[0002] Farmland is land used for growing crops. To increase crop yields, farmland irrigation systems are necessary to ensure proper irrigation and drainage, preventing floods caused by excess water and droughts caused by insufficient water. This allows crops to grow normally, ultimately increasing yields. Irrigation systems are used during farmland irrigation, significantly improving efficiency and reducing labor compared to traditional manual irrigation. Water resources...

[0003] A search revealed a farmland irrigation device disclosed in patent publication number CN220936055U. The device includes a main pipe and an adjusting mechanism. A valve is installed on one side of the main pipe, and a splicing mechanism is installed on the outer side of the main pipe. A first connecting pipe is fixedly installed on the outer side of the main pipe, and a first threaded pipe is sleeved on the outer side of the first connecting pipe. A secondary pipe is threadedly connected to one end of the first threaded pipe, and a support leg is fixedly connected to the outer side of the secondary pipe. An adjusting mechanism is installed at one end of the secondary pipe. Through the arrangement of a second threaded pipe, a second connecting pipe, a spraying device, a nozzle, an adjusting hole, an adjusting cover, and a second bolt, in use, the second connecting pipe and the secondary pipe are fixedly connected via the second threaded pipe. The spraying device is then connected to the secondary pipe to begin spraying water. Depending on the required water pressure, different sizes of adjusting holes on the nozzles can be selected by rotating the adjusting cover to achieve the desired spraying effect.

[0004] However, farmland irrigation devices still have the following shortcomings in actual use:

[0005] 1. A connecting pipe is connected to the outer wall of the main pipeline. An irrigation pipe is installed at the upper end of the connecting pipe, and a sprinkler is installed at the upper end of the irrigation pipe. Some irrigation pipes are not sealed at the upper end, which allows leaves to enter the irrigation pipe, causing water pollution and blockage of the irrigation pipe, reducing the quality of the water source and hindering the spraying irrigation, thus reducing the irrigation efficiency of farmland.

[0006] 2. Connect the main pipeline to the water pump, start the water pump, and pump water into the main pipeline. The water in the main pipeline enters the irrigation pipe through the connecting pipe. The water in the irrigation pipe is sprayed onto the farmland through the sprinklers to irrigate the farmland. However, it is inconvenient to adjust the amount of water sprayed by the sprinklers according to the actual irrigation situation of the farmland, and it is also inconvenient to adjust the water pressure. This causes the water to be always used to irrigate the same farmland area, resulting in excessive water spraying and hindering water conservation.

[0007] To address these issues, we provide a farmland water-saving irrigation device with automatic water supply and drainage control. Utility Model Content

[0008] The purpose of this utility model is to provide a water-saving irrigation device for farmland with automatic water supply and drainage control. By setting up a blocking component, it avoids pollution of water sources and blockage of irrigation pipes by leaves and other debris, allowing high-quality water to be used smoothly for irrigation. Furthermore, by setting up an automatic water supply and drainage control component, it adjusts the number of water nozzles to achieve the conversion of spray distance. By reducing the number of water nozzles and increasing water pressure to expand the spraying range, it avoids local over-irrigation, thereby achieving water conservation and solving the technical problems mentioned in the background art.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model relates to a water-saving irrigation device for farmland with automatic water supply and drainage control. It includes an irrigation pipe with a sealing assembly at its upper end.

[0016] The present invention is further configured such that a sealing ring fitted on the peripheral sidewall of the movable disc abuts against the inner wall of the irrigation pipe.

[0017] The present invention is further configured such that a protective shell is installed on the upper surface of the connecting plate, and a cover plate is installed on the side wall of the protective shell.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by setting a sealing component, presses down the connecting plate, and the sealing plug is filled inside the irrigation pipe. The connecting plate abuts against the upper end of the irrigation pipe, sealing the upper inlet of the irrigation pipe.
