Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, and in particular to an adjustable agricultural irrigation nozzle. Background Technology

[0002] In agricultural planting, irrigation methods have a significant impact on crop root absorption, water use efficiency, and overall growth. Currently, the most common irrigation methods include sprinkler irrigation and drip irrigation. Sprinkler irrigation uses nozzles to spray water in a mist onto the leaves and roots of crops, making it suitable for large areas of farmland. It can quickly replenish water and also has cooling and humidifying effects. Drip irrigation, on the other hand, uses drippers to slowly and evenly deliver water to the crop roots, offering advantages such as water conservation, fertilizer saving, and prevention of soil compaction. It is particularly suitable for high-precision irrigation scenarios such as greenhouses, fruit trees, and cash crops.

[0003] Most existing agricultural sprinklers are single-function structures, such as drip irrigation sprinklers or spray sprinklers, which make it difficult to flexibly switch irrigation modes according to the actual crop type, growth stage or soil moisture, resulting in low water resource utilization and even problems such as over-irrigation or under-irrigation. Utility Model Content

[0004] The main objective of this invention is to provide an adjustable agricultural irrigation nozzle, which aims to solve the problems mentioned in the background art.

[0005] To solve the above problems, this utility model proposes an adjustable agricultural irrigation sprinkler head, including a water inlet pipe, a plurality of water spray pipes fixedly spaced at the upper part of the water inlet pipe, a plurality of water drip pipes fixedly spaced at the lower part of the water inlet pipe, a connecting base fixedly spaced at the bottom end of the water inlet pipe, and a top cover fixedly spaced at the top end of the water inlet pipe.

[0006] An adjusting device is movably installed inside the water inlet pipe. A linkage rod is fixedly installed at the center of the bottom of the adjusting device, and a sliding valve is threadedly connected to the lower end of the linkage rod.

[0007] In one embodiment, the adjusting device includes a threaded rod with a rotating handle fixedly disposed at the top end of the threaded rod, and the lower end of the threaded rod passing through and threadedly connected to the top cover; an adjusting plug is fixedly disposed at the lower end of the threaded rod, and a sealing ring is fixedly disposed on both the top and bottom surfaces of the adjusting plug.

[0008] In one embodiment, the upper end of the linkage rod is installed at the center of the bottom of the adjusting plug, the lower end of the linkage rod is provided with a threaded section, an upper retaining ring is fixedly provided above the threaded section, and a lower retaining ring is fixedly provided at the lower end of the linkage rod.

[0009] In one embodiment, a sealing ring is fixedly arranged around the outer periphery of the sliding valve, and its internal structure is a hollow cavity with triangular compartments. A threaded connection groove is provided in the center, and the valve is threadedly connected to the linkage rod through the connection groove.

[0010] In one embodiment, a limiting groove is provided on the inner wall of the water inlet pipe near the bottom, and the sliding valve is installed in the limiting groove.

[0011] In one embodiment, there are no fewer than four drip tubes, which are evenly arranged around the lower outer periphery of the water inlet pipe at 90° intervals, and each drip tube has multiple drip heads installed at intervals at its lower end.

[0012] In one embodiment, there are no fewer than three water spray pipes, which are evenly arranged around the upper outer periphery of the water inlet pipe at 120° intervals. The bottom of each water spray pipe is installed at a 30° angle to the water inlet pipe, and each of them has a spray nozzle fixedly installed at its top.

[0013] Beneficial effects:

[0014] 1. This utility model constructs an integrated switching mechanism by setting an adjustment device, a linkage rod, and a sliding valve inside the water inlet pipe cavity. It enables free switching between sprinkler and drip irrigation modes by rotating the top handle without replacing parts or using external tools. When the rotating handle is rotated and pressed down, the adjustment plug moves down along the inner wall groove of the top cover, gradually blocking the water inlet channel of the upper sprinkler pipe. At the same time, it drives the lower linkage rod to descend synchronously along the limiting groove, releasing the seal on the lower drip pipe. This achieves a smooth transition from large-area spraying to root water-saving irrigation. This structure effectively improves the adaptability and ease of operation of the sprinkler head, meets the differentiated needs of different crops and different growth cycles for irrigation methods, and significantly improves irrigation efficiency and resource utilization.

[0015] 2. Users can quickly switch irrigation modes simply by rotating the handle, avoiding the tedious operation of changing nozzles or manual disassembly and assembly. It is especially suitable for fields where multiple crops are planted alternately or require phased irrigation. The adjustment device, through threaded drive, adjustment plug, and sealing ring, can precisely control the opening and closing of the water flow channel during sliding. The upper and lower sealing rings improve the airtightness of the structure, preventing water pressure leakage or crossflow, and ensuring the stable operation of the irrigation system. This device has low structural resistance and fast switching response, making it suitable for gravity water tower irrigation commonly used in rural areas, as well as low-pressure pump water supply systems in modern agriculture, with strong adaptability to the usage environment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To achieve the above-mentioned utility model objectives, such as Figure 1-4 As shown, this utility model provides an adjustable agricultural irrigation nozzle, including an inlet pipe 1, a plurality of spray pipes 3 fixedly spaced at the upper part of the inlet pipe 1, a plurality of drip pipes 2 fixedly spaced at the lower part of the inlet pipe 1, a connecting base 8 fixedly spaced at the bottom end of the inlet pipe 1, and a top cover 4 fixedly spaced at the top end of the inlet pipe 1.

[0025] An adjusting device 5 is movably installed inside the water inlet pipe 1. A linkage rod 6 is fixedly installed at the center of the bottom of the adjusting device 5, and a sliding valve 7 is threadedly connected to the lower end of the linkage rod 6. During operation, the connecting base 8 is first connected to the flange of the external water supply pipe to form a closed water passage in the water inlet pipe 1, completing the initial installation. Subsequently, the user operates the adjusting device 5 to switch between the required sprinkler or drip irrigation mode according to the crop irrigation needs.

[0026] The adjusting device 5 includes a threaded rod 51, with a rotating handle 52 fixedly mounted at the top end of the threaded rod 51. The lower end of the threaded rod 51 passes through the top cover 4 and is threadedly connected to it. An adjusting plug 53 is fixedly mounted at the lower end of the threaded rod 51, and sealing rings 54 are fixedly mounted on both the top and bottom surfaces of the adjusting plug 53. During operation, the user rotates the rotating handle 52, causing the threaded rod 51 to rotate downward along the threaded hole in the center of the top cover 4, thereby driving the adjusting plug 53 at the lower end to slide downward. During the downward movement of the adjusting plug 53, its outer circumferential sealing ring 54 is tightly attached to the inner wall of the water inlet pipe 1, effectively preventing water leakage and gradually sealing the water inlet channel connected to the upper spray pipe 3, thereby shutting off the sprinkler irrigation function.

[0027] The upper end of the linkage rod 6 is installed at the center of the bottom of the adjusting plug 53. The lower end of the linkage rod 6 has a threaded section, and an upper retaining ring 61 is fixedly installed above the threaded section. A lower retaining ring 62 is fixedly installed at the lower end of the linkage rod 6. A sealing ring 71 is fixedly arranged around the outer periphery of the sliding valve 7. Its internal structure is a hollow cavity with triangular compartments. A threaded connection groove is provided in the center, and it is threadedly connected to the linkage rod 6 through the connection groove. During operation, when the adjusting plug 53 moves down, it drives the linkage rod 6 to move down synchronously, so that the sliding valve 7 threadedly connected to the linkage rod 6 slides down along the limiting groove 11. As the sliding valve 7 disengages from the sealing position on the outlet of the drip pipe 2, water can enter the drip pipe 2 from the inlet pipe 1. Through multiple drip irrigation heads 21 at the bottom, it provides slow-flow, precise irrigation to the plant root area, realizing a smooth switch from sprinkler irrigation to drip irrigation mode.

[0028] The inner wall of the water inlet pipe 1 is provided with a limiting groove 11 near the bottom, and the sliding valve 7 is installed in the limiting groove 11. During operation, the sliding valve 7 can move axially in the limiting groove 11 under the drive of the linkage rod 6, and block or open the water outlet channel of the drip pipe 2 at a designated position. It has good guiding and positioning accuracy, ensuring a smooth and reliable switching process.

[0029] The number of drip pipes 2 is no less than 4, which are evenly arranged around the lower outer periphery of the water inlet pipe 1 at 90° intervals. Each drip pipe 2 has multiple drip heads 21 installed at intervals at its lower end. When in operation, after the water flows into the drip pipe 2, it slowly seeps out through the drip head 21 and directly acts on the soil area around the crop roots, forming a precise irrigation effect of fixed point, low pressure, and water saving, which greatly reduces water waste and is suitable for crops with high requirements for water volume control.

[0030] The number of water spray pipes 3 is no less than three, which are evenly arranged around the upper outer periphery of the water inlet pipe 1 at 120° intervals. The bottom of each water spray pipe 3 is installed at a 30° angle to the water inlet pipe 1, and each of them is fixedly equipped with a sprinkler head 31. When in operation, the water flow rises from the water inlet pipe 1 to each water spray pipe 3, and is sprayed out as a high-pressure mist water column through the sprinkler head 31, forming a wide-range, multi-angle coverage irrigation. It is suitable for early seedling cultivation, rapid cooling and improving the moisture environment of crops, and significantly improves irrigation efficiency.

[0031] The working principle of this utility model is as follows: When in use, the user first connects the connecting base 8 located at the bottom of the water inlet pipe 1 to the external water supply pipe flange to ensure a stable water supply. The internal water passage path can be adjusted by rotating the handle 52 to select the desired irrigation method. When the adjusting device 5 is in the rising state, the adjusting plug 53 does not block the water inlet of the spray pipe 3, and the sliding valve 7 is located at the upper part of the limiting groove 11 to close the water outlet of the drip pipe 2. At this time, water will flow from the upper end of the inlet pipe 1 into multiple spray pipes 3, and spray outward at a 30° angle through the top sprinkler head 31, forming a wide-area, high-coverage atomized water column to achieve multi-angle sprinkler irrigation. It is suitable for the early stage of crop growth or large-area water replenishment needs. When the user rotates the handle 52 clockwise, the threaded rod 51 moves downward under the guidance of the thread on the inner wall of the top cover 4, driving the adjusting plug 53 to descend and close the water inlet of the spray pipe 3. At the same time, the linkage rod 6 moves downward under control, and the threaded section drives the sliding valve 7 to slide downward in the limiting groove 11, gradually opening the water outlet channel of the drip pipe 2, so that water can slowly seep out from multiple drip heads 21 to perform targeted fine irrigation of the crop roots and reduce water waste. During the entire switching process, the adjusting plug 53 is sealed with the inner wall of the inlet pipe 1, and the sealing rings 54 at its upper and lower ends achieve double sealing. The sliding valve 7 is provided with a sealing ring 71, which always fits against the inner wall of the limiting groove 11 during the up and down movement, ensuring no leakage when the water path is switched, and ensuring the irrigation efficiency and sealing reliability of the system.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
