Description
Technical Field
[0001] This invention relates to the field of irrigation technology, specifically to an intelligent water-saving irrigation and precision fertilization device for facility agriculture. Background Technology
[0002] With the rapid development of modern facility agriculture, integrated water and fertilizer technology has become an important means to improve crop yield and quality. In facility agriculture environments such as greenhouses, the precise delivery of water and nutrients to the roots or leaves of crops through irrigation systems is a key link in achieving intensive and efficient agricultural production.
[0003] While current irrigation and fertilization equipment can meet basic agricultural production needs, it still faces some technical bottlenecks in practical applications. Traditional sprinkler irrigation systems mostly use fixed nozzles with simple structures, and their spray angles and water flow patterns are usually preset and unchangeable. However, different types of crops vary significantly in morphology, height, and water requirements. Even for the same crop, the required water flow intensity and coverage differ during the seedling, growth, and maturity stages. For example, seedlings typically require fine misting irrigation to prevent water flow damage, while vigorous growth requires a larger direct flow to penetrate the soil. Existing single-mode irrigation equipment struggles to adapt flexibly to these changes without replacing components, resulting in low irrigation efficiency or inefficient water resource utilization.
[0004] Furthermore, the dissolution and mixing of solid fertilizers directly affect the quality of fertilization when implementing integrated water and fertilizer management. Conventional fertilization equipment lacks pre-treatment mechanisms for fertilizers, making solid fertilizers highly susceptible to moisture absorption and clumping during storage. When these clumped fertilizers are directly added to the dissolving tank, they often fail to dissolve completely in a short time. This not only leads to fluctuations in fertilizer concentration in irrigation water, potentially causing uneven nutrient absorption by crops or even "seedling burn," but also results in undissolved particles easily accumulating in pipelines or clogging precision nozzles, increasing the difficulty of equipment maintenance. Simultaneously, existing water and fertilizer mixing equipment typically requires high-powered electric mixers to ensure uniform mixing, which increases manufacturing costs and operating energy consumption, hindering energy conservation and emission reduction in agricultural production.

The inside of the feeding box 3011 is fixedly connected to the limiting frame 3012. Specifically, by pouring the water-fertilizer into the feeding box 3011, after the water enters the dissolving tank 304, the motor 302 drives the rotating rod 303 to rotate, which in turn moves the stirring rod 3015 to agitate the interior, dissolving the water-fertilizer.

[0026] A conveying pipe 4 is fixedly connected to the outer wall of the dissolving tank 304. A water storage tank 2 is fixedly connected to one end of the conveying pipe 4.

A water pump 13 is fixedly connected to the upper surface of the support plate 14. A connecting pipe 12 is fixedly connected to the input end of the water pump 13. One end of the connecting pipe 12 is fixedly connected to the outer wall of the water storage tank 2. A conveying pipe 11 is fixedly connected to the output end of the water pump 13.

Water inside water storage tank 2 enters the interior of dissolving tank 304 through conveying pipe 4. Water pump 2 is started to pump water out of water storage tank 2 through connecting pipe 2 12 and convey it to the interior of mixing tank 502 through conveying pipe 3 11. Dissolved fertilizer in dissolving tank 304 is conveyed to mixing tank 502 through connecting pipe 10 for mixing.
[0027] Working principle: First, water and fertilizer are poured into the feeding box 3011. After the water enters the dissolving tank 304, the motor 302 drives the rotating rod 303 to rotate, which in turn moves the stirring rod 3015 to agitate the interior, dissolving the water and fertilizer. The rotation of the rotating rod 303 causes the bevel gear 3016 to rotate, which in turn drives the rotating rod 3016 to rotate the bevel gear 3013. The bevel gear 3013 then drives the rotating rod 306 to rotate on the fixed block 3. The rotating rod 306 rotates within the 05, causing the rotating rod 306 to drive the rotating disk 307 to rotate. This causes the rotating disk 307 to drive the connecting rod 308 to move, allowing the connecting rod 308 to rotate on the rotating disk 307 and drive the sliding rod 3010 to slide on the limiting sleeve 309. This causes the sliding rod 3010 to drive the feeding box 3011 to move, and the feeding box 3011 to drive the limiting plate 3014 to slide on the limiting frame 3012, thereby screening the water and fertilizer. The dissolved fertilizer is transported to the mixing tank 502 through the connecting pipe 10. The water in the storage tank 2 is pumped out through the connecting pipe 2 12 by the water pump 2 13 and transported into the mixing tank 502 through the delivery pipe 3 11. The water enters the mixing tank 502 and drives the water wheel 503 to rotate. At the same time, the rotating rod 3 504 rotates inside the mixing tank 502, thereby driving the stirring rod 2 505 to move and mix the dissolved fertilizer and water in the mixing tank 502. Then, the water in the mixing tank 502 is pumped out by the water pump 1 506 and transported into the delivery pipe 2 507 and then into the water supply pipe 2 15. After mixing, the water and fertilizer enter the water supply pipe 9 through the second water supply pipe 15, and then the water enters the spray pipe 706. The output end of the electric actuator 702 pushes the connecting rod 703 to slide within the limiting block 606. The movement of the rotating rod 603 drives the limiting rod 704 to move, which in turn pushes the adjusting rod 705 to move and rotate within the spray pipe 706. The water flow is controlled by the screw thread moving within the spray pipe 706. The starting motor 801 drives the rotating rod 802 to rotate, which in turn rotates within the limiting block 606. The rotating rod 802 drives the worm gear 804 to rotate, which in turn drives the worm wheel 803 to rotate, causing the nozzle 805 to rotate within the spray pipe 706. The nozzle 805 is separated by the partition plate 806, allowing it to switch between direct spraying and atomized irrigation modes while rotating. The output of motor 602 drives rotating rod 603 to rotate, which in turn drives transmission gear 604 to rotate. Transmission gear 604 drives chain 608 to move, which in turn drives transmission gear 607 to rotate. Transmission gear 607 drives connecting block 605 to rotate, which in turn drives water pipe 9 to rotate on water pipe 15, thereby adjusting the spray angle.
