Description

Technical Field

[0001] This utility model relates to the field of vegetable drip irrigation equipment, and in particular to a vegetable water and fertilizer integrated drip irrigation device. Background Technology

[0002] The integrated water and fertilizer drip irrigation system for vegetables is a highly efficient and precise agricultural irrigation and fertilization device. It delivers water and nutrients directly to the roots of plants through drippers, achieving precise irrigation and avoiding water waste. With its high efficiency, economy, and environmental friendliness, the integrated water and fertilizer drip irrigation system for vegetables has become an important method of modern agricultural irrigation.

[0003] Existing drip irrigation systems for vegetables typically have a fixed mixing ratio of water and fertilizer, or they are simply mixed manually in approximate proportions. This results in low precision and makes it difficult to adjust the mixture flexibly and accurately according to the actual needs of the soil. This can easily lead to situations where there is too much or too little nutrient or water, which not only causes unstable growth of vegetables but also easily results in the waste of water and fertilizer.

[0004] Therefore, existing integrated water and fertilizer drip irrigation devices for vegetables typically use a fixed water and fertilizer mixing ratio, or are simply mixed manually in approximate proportions. This low precision makes it difficult to adjust flexibly and precisely according to the actual needs of the soil, easily leading to excessive or insufficient nutrient and water intake. This not only causes unstable vegetable growth but also easily results in water and fertilizer waste. By installing a first metering device and a second metering device on the outside of the fertilizer tank and the connection between the water inlet pipe and the storage tank in existing integrated water and fertilizer drip irrigation devices, the amount of water and fertilizer can be precisely controlled. By installing a soil rapid testing instrument to detect soil composition, the detection information can be transmitted to the central control module for comprehensive analysis, thereby triggering the central control module to automatically control the water and fertilizer ratio at the first and second metering devices. This achieves precise water and fertilizer ratio, allowing the drip irrigation pipe to deliver the most suitable nutrients to the vegetables, ensuring vegetable quality and growth stability. Drip irrigation using precise ratios is less likely to cause over-fertilization and is more resource-efficient. Utility Model Content

[0005] To overcome the limitations of existing drip irrigation devices that typically use a fixed mixing ratio of water and fertilizer, or rely on manual mixing at approximate proportions, which results in low precision and makes it difficult to adjust the ratio flexibly and accurately according to the actual needs of the soil, it is easy to cause situations where there is too much or too little nutrient and water during drip irrigation. This not only leads to unstable vegetable growth but also easily causes waste of water and fertilizer.

[0015] 1. By installing a first metering device and a second metering device on the outside of the connection between the fertilizer tank and the water inlet pipe and the storage tank of the existing vegetable water and fertilizer integrated drip irrigation device, the amount of water and fertilizer can be precisely controlled.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of a vegetable water and fertilizer integrated drip irrigation device, including a storage tank 1, a fertilizer tank 2, a guide pipe 3, a first metering device 4, a water inlet pipe 5, a second metering device 6, a drip irrigation pipe 7, a hydraulic controller 8, a main control module 9, and a soil rapid tester 10. The upper end of the storage tank 1 is provided with a fertilizer tank 2 for storing fertilizer. The fertilizer tank 2 and the storage tank 1 are fixedly connected by the guide pipe 3. The outside of the guide pipe 3 is provided with a control valve for controlling the inflow and outflow of fertilizer. The first metering device 4 for accurately controlling the amount of fertilizer output is fixedly installed at the control valve outside the guide pipe 3. The upper right part of the storage tank 1 is fixedly installed with a water inlet pipe 5 for introducing water. The outside of the connection between the water inlet pipe 5 and the storage tank 1 is provided with a control valve for controlling the inflow and outflow of water. The second metering device 6 for accurately controlling the amount of water inflow is fixedly installed at the control valve outside the water inlet pipe 5. The left end of the storage tank 1 near the bottom is fixedly installed with a drip irrigation pipe 7 for drip irrigation of vegetables.

[0025] Please see Figure 1 and Figure 3In this embodiment, a control valve for controlling the inflow and outflow is provided on the outer side of the connection between the drip irrigation pipe 7 and the storage tank 1. A hydraulic controller 8 for controlling the hydraulic pressure is fixedly installed at the control valve on the outer side of the drip irrigation pipe 7. A main control module 9 for controlling the first meter 4, the second meter 6, and the hydraulic controller 8 is fixedly installed at the front middle of the storage tank 1. The first meter 4, the second meter 6, the hydraulic controller 8, and the main control module 9 are all electrically connected to each other via connecting wires. A soil rapid tester for detecting soil temperature, humidity, and nitrogen, phosphorus, and potassium components is fixedly installed on the upper left end of the main control module 9. The soil rapid tester 10 is model TPY-7PC. The left end of the soil rapid tester 10 is equipped with a soil detection head 11 for inserting into the ground to test the soil. The soil detection head 11 is electrically connected to the soil rapid tester 10 via a connecting cable. The main control module 9 is equipped with a data processing module for processing information, a communication module for controlling the overall operation, and a controller. The soil information detected by the soil detection head 11 is transmitted to the main control module 9 in the form of an electrical signal to trigger the main control module 9 to automatically control the first metering device 4, the second metering device 6, and the hydraulic controller 8.

[0026] Please see Figures 4-5 In this embodiment, drip holes 13 for dripping water and nutrients into vegetables are evenly distributed from left to right at the lower end of the drip irrigation pipe 7. Four sets of clamps 14 for supporting the drip irrigation pipe 7 are evenly distributed from left to right at the lower end of the drip irrigation pipe 7. A post 15 for inserting into the ground is fixedly connected to the middle of the lower end of the clamp 14. A protective pad 16 for protecting the drip irrigation pipe 7 is attached to the inner side of the clamp 14. By setting the protective pad 16, its toughness can be used to protect the drip irrigation pipe 7 and avoid damaging the drip irrigation pipe 7.

[0027] Please see Figure 1 and Figure 6 In this embodiment, a drive motor 17 for driving the rotating shaft 18 to rotate is fixedly installed at the lower middle part of the storage tank 1. The rotating shaft 18 extends through the lower end of the storage tank 1 into its interior. Stirring rods 19 for mixing water and fertilizer are evenly and fixedly installed around the surface of the rotating shaft 18. Five sets of guide holes 20 for reducing rotational resistance are evenly distributed on the surface of the stirring rods 19. The drive motor 17 drives the stirring rods 19 to rotate synchronously by driving the rotating shaft 18 to rotate. The upper end of the fertilizer tank 2 is provided with a sealing cover 12 for opening and closing. Four sets of support columns 21 for supporting the storage tank 1 are fixedly installed around the lower side of the storage tank 1. Support seats 22 for increasing support stability are fixedly installed at the lower end of the support columns 21. Protrusions 23 for inserting into the ground are evenly and fixedly installed around the lower end of the support seats 22.

[0028] When working, first take the device to the vegetable planting area, fix the device in the corresponding position, insert the protrusion 23 at the lower end of the support base 22 into the ground, and use the clamp 14 to support the drip irrigation pipe 7, so that the insertion post 15 at its lower end is inserted into the ground, ensuring that the liquid storage tank 1 and the drip irrigation pipe 7 remain stable.

[0029] Then open the sealing cap 12 at the top of the fertilizer tank 2 and introduce the fertilizer into the fertilizer tank 2, and connect the water inlet pipe 5 to the external water supply source;

[0030] Then, the soil detection head 11 of the soil rapid tester 10 is inserted into the soil of the vegetable planting area to detect the moisture and nutrient content in the soil. The detected data is transmitted to the main control module 9 in the form of an electrical signal. After analysis by the main control module 9, the first metering device 4 and the second metering device 6 are automatically triggered to work, and the water and material output are precisely controlled according to the actual soil conditions.

[0031] Next, the water and fertilizer entering the storage tank 1 are stirred. The drive motor 17 drives the rotating shaft 18 to rotate the stirring rod 19, so that the stirring rod 19 mixes the water and fertilizer evenly by rotating.

[0032] Then, the hydraulic controller 8 is controlled by the main control module 9 to adjust the hydraulic pressure at the drip irrigation pipe 7 to a suitable level, so that the mixed water and fertilizer enter the drip irrigation pipe 7 from the storage tank 1 and drip onto the vegetables through the drip hole 13;

[0033] Finally, when the soil sensor 11 detects that the water and nutrient content in the soil has reached the level required for vegetable growth, the main control module 9 will automatically control the hydraulic controller 8 to stop working, that is, stop drip irrigation of nutrients to the vegetables.

[0034] Through the above steps, by installing a first metering device 4 and a second metering device 6 on the outside of the connection between the fertilizer tank 2 and the water inlet pipe 5 and the storage tank 1 of the existing vegetable fertigation drip irrigation device, the amount of water and fertilizer can be precisely controlled. By setting up a soil rapid tester 10 to detect the soil composition content, the detection information can be transmitted to the central control module 9 for comprehensive analysis, thereby triggering the central control module 9 to automatically control the water-fertilizer ratio at the first metering device 4 and the second metering device 6, achieving precise water-fertilizer ratio. This allows the drip irrigation pipe 7 to drip the most suitable nutrients to the vegetables, ensuring the quality and growth stability of the vegetables. Drip irrigation through precise ratio is less likely to cause over-fertilization, saving more resources. This solves the problem that the existing vegetable fertigation drip irrigation devices usually have a fixed water-fertilizer mixing ratio, or are only mixed manually according to an approximate ratio, which has low precision and is not convenient to flexibly and accurately adjust according to the actual needs of the soil. It is easy to have too much or too little drip irrigation nutrients and water, which not only leads to unstable vegetable growth, but also easily causes waste of water and fertilizer.
