Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water-saving irrigation, and particularly relates to an agricultural irrigation water-saving device. BACKGROUND

[0002] Agricultural irrigation is an important agricultural management technique, which has a profound impact on crop growth. With climate change and population growth, scientific and rational irrigation management is crucial for improving crop yields and ensuring food security.

[0003] The existing agricultural irrigation methods can be divided into sprinkling irrigation, drip irrigation and infiltration irrigation. These irrigation techniques generally have good water-saving performance and higher water utilization rate than traditional irrigation modes. However, they also have some drawbacks.

[0004] In existing agricultural irrigation, although techniques such as sprinkling irrigation and drip irrigation improve water resource utilization, there are still significant defects:

[0005] Continuous irrigation leads to water waste: existing equipment continuously sprays water, and the soil cannot fully absorb it, resulting in evaporation or runoff (such as the CN112293020A patent still has this problem);

[0006] Insufficient adjustment capability: fixed height nozzles cannot adapt to the height changes during the growth cycle of crops (such as the difference in plant height from seedling to maturity); the coverage adjustment relies on manual displacement, which is inefficient;

[0007] Low degree of intelligence: lack of regional irrigation strategies for different drought levels, which can lead to uneven irrigation.

[0060] Embodiment two:

[0061] Please refer to Figures 1-9 The working principle of the agricultural irrigation water-saving device is shown in the figure:

[0062] 1. Alternate zoning irrigation

[0063] Core components: The upper alternate cavity 3026 is divided into three 120° sectors by the rotating shaft 3028 and the three partition plates 3029 inside the alternate irrigation box 302.

[0064] Working process:

[0065] Water flows into the alternating cavity 3026 from the three-way water inlet 3030. The partition plate 3029 between the two positioning blocks 3031 and the partition plate 3029 above the extrusion spherical surface 3037 form a water storage space. When the water in the space reaches a certain weight, the extrusion spherical surface 3037 retracts, the partition plate 3029 pushes the rotating shaft 3028 to rotate, and the partition plate 3029 above the extrusion spherical surface 3037 moves to below it. The partition plate 3029 on the other side moves to above the extrusion spherical surface 3037 on the other side, so that it forms a new water storage space with the partition plate 3029 between the two positioning blocks 3031.

[0066] During rotation, the water in the water storage space falls into the same-side shunt cavity separated by the shunt plate 3038. The water flows into the irrigation water pipe 3022 through the S-shaped water inlet pipe 3025 connected in the same-side shunt cavity, and then is sprayed out through the irrigation nozzle 3023.

[0067] The shunt plate 3038 of the shunt cavity 3027 uniformly distributes water to the two irrigation water pipes 3022, realizes intermittent and partitioned irrigation, and allows the soil to have a water absorption buffer time.

[0068] 2. Height and angle adjustment

[0069] Nozzle height: Adjust the adjusting screw 3019 on the rotating irrigation support 3012 to drive the movable support rod 3020 to rise and fall, so as to adapt to different crop heights.

[0070] Overall support height: The servo motor 1020 drives the worm 1019, the worm 1019 meshes with the turbine 1018 to drive the lead screw 1017 to rotate, and the movable support plate 1012 rises and falls to adjust the height of the horizontal rod 102 from the ground.

[0071] Irrigation coverage: The electric telescopic rod 208 pushes the sliding block 3011 to slide on the horizontal rod 102, and the linkage telescopic fork 204 expands / contracts, so as to change the horizontal coverage width of the irrigation assembly 3.

[0072] 3. Waterway system

[0073] When alternating irrigation is needed, valve B 3015 is closed, valve A 404 and water pump 403 are opened to draw water from the water storage tank 401, and the water flows through the main water pipe 402, the telescopic hose 3039, and the alternating irrigation box 302 in sequence.

[0074] When continuous irrigation is needed, valve A 404 is closed, valve B 3015 and water pump 403 are opened to draw water from the water storage tank 401, and the water flows through the continuous water pipe 405, the U-shaped water pipe 406, the corrugated telescopic pipe, the S-shaped water inlet pipe 3025, the irrigation water pipe 3022, and the irrigation nozzle 3023 in sequence.

[0075] The filter screen 4010 of the plugboard 409 intercepts impurities, and regular cleaning can maintain water quality.

[0076] Example three:

[0077] Please refer to Figures 1-9 The embodiment is a method for using an agricultural irrigation water-saving device:

[0078] 1. Installation and initial setup

[0079] Support and fixation: Fix the mounting plates 1013 of the two adjustable support legs 101 to the two sides of the farmland through anchor bolts, and ensure that the horizontal bar 102 is kept horizontal.

[0080] Waterway connection:

[0081] Connect the water inlet 4011 of the external water source to the water storage tank 401, open the water inlet valve 4012, and fill water to the preset water level.

[0082] The main water pipe 402 is connected to the three-way water inlet 3030 of all alternating irrigation boxes 302 through a series of flexible hoses 3039, forming a closed loop pipeline.
