Description

Technical Field

[0001] The invention belongs to the technical field of water-saving irrigation, and in particular relates to an agricultural irrigation water-saving device. Background Art

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

[0003] Existing agricultural irrigation methods can generally be divided into sprinkler irrigation, drip irrigation, and infiltration irrigation. These irrigation technologies generally have good water-saving performance and higher water utilization efficiency than traditional irrigation methods. Of course, they also have some drawbacks.

[0004] In existing agricultural irrigation, although technologies such as sprinkler irrigation and drip irrigation have improved water resource utilization, they still have significant drawbacks: Continuous irrigation leads to water waste: Existing equipment often sprays water continuously, which the soil cannot fully absorb, and some water evaporates or flows away (this problem still exists in the CN112293020A patent); Insufficient adjustment capability: Fixed-height sprinklers are difficult to adapt to height changes during the crop growth cycle (such as plant height differences from seedlings to maturity); coverage adjustment relies on manual shifting, which is inefficient; Low level of intelligence: There is a lack of regionalized irrigation strategies tailored to different degrees of drought, which easily leads to uneven irrigation.

[0005] The present invention aims to solve the above technical bottlenecks through zoned alternating irrigation, multi-dimensional adjustment mechanism and intelligent control system. Summary of the Invention

[0034] Example 2:

[0035] See also Figures 1-9 As shown, this embodiment shows the working principle of an agricultural irrigation water-saving device: 1. Alternate zone irrigation Core components: The interior of the alternating pouring box 302 is divided into three 120° sector-shaped areas by a rotating shaft 3028 and three partition plates 3029.

[0036] Working process: Water flows into the alternating chamber 3026 from the three-way water inlet 3030, and the partition plate 3029 located between the two positioning blocks 3031 and the partition plate 3029 located above the extrusion sphere 3037 form a water storage space. When the water in the space reaches a certain weight, the extrusion sphere 3037 retracts, and the partition plate 3029 pushes the rotating shaft 3028 to rotate, causing the partition plate 3029 located above the extrusion sphere 3037 to move below it, and the partition plate 3029 on the other side moves to above the extrusion sphere 3037 on the other side, forming a new water storage space with the partition plate 3029 located between the two positioning blocks 3031.

[0037] During the rotation process, the water in the water storage space falls into the diversion cavity on the same side separated by the partition baffle 3038, and the water flows into the irrigation water pipe 3022 through the S-shaped water inlet pipe 3025 connected to the diversion cavity on the same side, and then is sprayed out through the irrigation nozzle 3023.

[0038] The partition baffle 3038 of the diversion chamber 3027 evenly distributes water to the irrigation pipes 3022 on both sides, realizing intermittent zoned irrigation and allowing the soil to have a buffer time to absorb water.

[0039] 2. Height and angle adjustment Nozzle height: Rotate the adjustment screw 3019 on the irrigation bracket 3012 to drive the movable support rod 3020 to rise and fall to adapt to different crop heights.

[0040] Overall bracket height: The servo motor 1020 drives the worm 1019, and the worm 1019 engages with the turbine 1018 to drive the screw 1017 to rotate, driving the movable support plate 1012 to rise and fall, and adjusting the height of the cross bar 102 from the ground.

[0041] Irrigation coverage: The electric telescopic rod 208 pushes the slider 3011 to slide on the crossbar 102, linking the telescopic fork 204 to expand / contract, thereby changing the lateral coverage width of the irrigation assembly 3.

[0042] 3. Waterway system When alternate irrigation is required, valve B3015 is closed, valve A404 is opened, and water pump 403 is used to pump water from water storage tank 401. The water passes through main water pipe 402, telescopic hose 3039, and alternate irrigation box 302 in sequence.

[0043] When continuous irrigation is required, close valve A404, open valve B3015 and pump 403 to pump water from the water tank 401. The water enters the irrigation water pipe 3022 through the continuous water pipe 405, U-shaped water pipe 406, corrugated expansion pipe, and S-shaped water inlet pipe 3025 in sequence, and is then sprayed out through the irrigation nozzle 3023.

[0044] The filter 4010 of the plug board 409 intercepts impurities and can be cleaned regularly to maintain water quality.

[0045] Example 3:

[0046] See also Figures 1-9 As shown, this embodiment is a method for using an agricultural irrigation water-saving device: 1. Installation and Initial Setup Support and fixation: Fix the mounting plates 1013 of the two adjustable support legs 101 to both sides of the farmland through anchor bolts to ensure that the crossbar 102 remains horizontal.

[0047] Water connection: An external water source is connected to the water inlet 4011 of the water storage tank 401, and the water inlet valve 4012 is opened to fill water to a preset water level.

[0048] The main water pipe 402 is connected to the three-way water inlets 3030 of all the alternate watering boxes 302 through the telescopic hoses 3039 connected in series, forming a closed-loop pipeline.

[0049] Circuit configuration: The control box 4014 is connected to the power supply, and the circuit is connected to the solenoid valve 3040, the electric telescopic rod 208 and the servo motor 1020 to complete the system initialization self-test.

[0050] 2. Dynamic adjustment operation Nozzle height: For different crops (e.g., seedling stage / mature stage), the adjusting screw 3019 on the irrigation bracket 3012 is rotated, and the movable support rod 3020 is accurately raised or lowered to the target height (e.g., 20 cm in the seedling stage, 50 cm in the mature stage) through the scale indication of the guide rod 3021.

[0051] Overall bracket height: The servo motor 1020 is started through the control box 4014, driving the worm 1019 to drive the turbine 1018, causing the screw 1017 to rotate, pushing the movable support plate 1012 to slide in the adjustment square tube 1015, thereby achieving stepless adjustment of the height of the cross bar 102 from the ground (adjustment range: 0.5-1.5m).

[0052] Cover width adjustment: The operating control box 4014 starts the electric telescopic rod 208, pushing the first slider 3011 to move along the slide groove 104 of the cross bar 102 (the pulley 3016 and the ball 3017 cooperate to guide), and the telescopic fork 204 is linked to expand or contract, and the coverage width can be expanded from 2m to 6m.

[0053] Irrigation mode started Alternating zone irrigation mode: Close valve B3015, open valve A404 and water pump 403, and water flows through the main water pipe 402 into the alternating chamber 3026.

[0054] The water flow impacts the partition plate 3029 to store water. When the weight exceeds the pre-tightening force of the extrusion spring 3035, the extrusion sphere 3037 retracts and the rotating shaft 3028 rotates to allow the adjacent sector areas to receive water. At the same time, rotating the threaded pull rod 3034 can adjust the pre-tightening force of the extrusion spring 3035, thereby flexibly adjusting the water storage capacity of the water storage space.

[0055] The water flows through the S-shaped water inlet pipe 3025 on the same side of the diversion chamber 3027 and is transported to the irrigation nozzle 3023 to achieve field zone rotation irrigation.

[0056] Continuous irrigation mode: Close valve A404, open valve B3015 and water pump 403, and water flows through continuous water pipe 405 and U-shaped water pipe 406 directly into irrigation water pipe 3022, realizing continuous sprinkler irrigation in the entire area.

[0057] 4. Intelligent control and maintenance Parameter customization: The opening and closing timing of the solenoid valve 3040 is set through the control box 4014 to force the adjustment of the zoning irrigation rhythm (such as extending the irrigation time of a single zone in a drought area).

[0058] Filter maintenance: regularly pull the handle 4013 of the plugboard 409, pull out the plugboard along the slide rail 408, flush the sediment and impurities trapped in the filter screen 4010, and then reset it.

[0059] Antifreeze protection: In winter, drain the water tank 401 and the water in the pipes, disassemble the irrigation nozzle 3023 to clean the scale, and apply anti-rust grease to the moving parts.
