Description
Technical Field
[0001] This utility model relates to the field of irrigation technology, and in particular to an integrated water and fertilizer irrigation system for soft-seed pomegranates. Background Technology
[0002] As a distinctive fruit tree variety with both economic and nutritional value, the soft-seeded pomegranate has stringent requirements for the timing and precision of water and nutrient supply during its growth and development. During the budding stage, the root system needs to be kept moist to promote new shoot growth; during the flowering and fruit setting stage, irrigation must be controlled to prevent flower and fruit drop; during the fruit enlargement stage, balanced water and fertilizer are needed to improve fruit sweetness and seed plumpness; and before maturity, irrigation must be strictly stopped to prevent fruit cracking. With the development of intensive and water-saving agriculture, integrated water and fertilizer technology has become the core support for the efficient cultivation of soft-seeded pomegranates. This technology dissolves soluble fertilizers in water through an irrigation system, using water as a carrier to synergistically transport water and fertilizer to the crop root zone, significantly improving water and fertilizer utilization efficiency and reducing resource waste.
[0003] Most existing irrigation execution components are single-function, fixed designs. Some systems are only equipped with drip irrigation heads, which can achieve targeted water and fertilizer supply to the roots, but cannot handle large-area spraying during hot and dry seasons, requiring additional sprinkler irrigation equipment. Furthermore, long-term single drip irrigation can easily lead to uneven water and fertilizer penetration due to soil compaction. Other systems rely solely on sprinkler heads, which can cover the leaves and ground surface, but have a high water evaporation loss rate and cannot accurately deliver water and fertilizer to the core root zone of soft-seeded pomegranates, resulting in water and fertilizer waste. If the needs of different growth stages need to be met, irrigation components need to be replaced manually or two systems need to be built in parallel, which is cumbersome and has high equipment investment costs. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an integrated water and fertilizer irrigation system for soft-seeded pomegranates, thereby solving the problems mentioned in the background section. To achieve the above objective, the present utility model adopts the following technical solution: The integrated water and fertilizer irrigation system for soft-seed pomegranates includes a water supply system, a fertilizer supply system, a main pipeline, and multiple branch pipelines. The water supply system and the fertilizer supply system are respectively connected to the main pipeline, and the multiple branch pipelines are respectively connected to the main pipeline. Each branch pipeline is equipped with a drip irrigation nozzle at its end. The drip irrigation nozzle includes a spray valve body, a drip irrigation valve body, a valve core, a flow guide, and an adjusting component. The spray valve body and the drip irrigation valve body are detachably connected. The valve core is rotatably disposed within the spray valve body and the drip irrigation valve body, and its side wall has a valve core flow channel. Its top end extends outside the spray valve body.

[0005] Optionally, the spray valve body has a first valve core channel opened along its axial direction and a water inlet chamber opened along its radial direction. The first flow channel is opened on the side wall of the first valve core channel and connects to the spray part. The water inlet channel connects to the water inlet chamber.
[0006] Optionally, a second valve core channel is provided inside the drip irrigation valve body along its axial direction. The second valve core channel is connected to the first valve core channel. The second flow channel is opened on the side wall of the second valve core channel. The second flow channel is connected to the drip irrigation part, and the second flow channel is arranged opposite to the first flow channel.
[0007] Optionally, the valve core includes a valve body and a connecting rod. The valve core flow channel is opened along the axial direction of the valve body on one side of the valve body. The connecting rod is disposed at one end of the valve body and extends to the outside of the water spray valve body, and is connected to the adjusting member. When the valve core is rotated to one side, the valve core flow channel communicates with the first flow channel. When the valve core is rotated to the other side, the valve core flow channel communicates with the second flow channel.
[0008] Optionally, the drip irrigation part is conical to facilitate insertion into the soil. It has a spiral flow channel on its outer wall and a drip irrigation channel inside. The drip irrigation channel is connected to the second flow channel. The bottom of the spiral flow channel has multiple drip irrigation holes, which are connected to the drip irrigation channel.
[0009] Optionally, the spray section has an annular cavity inside, the annular cavity is connected to the first flow channel, and the spray section has a plurality of spray holes equidistantly opened on its periphery at one end away from the drip irrigation valve body.
[0010] Optionally, the guide member is conical with its conical surface facing the water spray section, and a through hole is provided in its middle section. The through hole is slidably connected to the connecting rod to adapt to different water pressures, thereby automatically adjusting the height.
[0011] Optionally, a limiting post is provided on one side of the valve body, and an arc-shaped limiting groove is provided on the top of the drip irrigation valve body along its radial direction. The limiting post matches and slides with the arc-shaped limiting groove to limit the radial and axial movement of the valve core.
[0012] Optionally, the water supply system includes a water tower, a first valve, a first water pump, a first pressure gauge, a backwash filter, a second pressure gauge, and a first check valve, which are connected in sequence through a water supply pipeline.
[0013] Optionally, the fertilizer supply system includes a water and fertilizer tank, a second water pump, a third pressure gauge, and a second check valve, which are connected in sequence through a fertilizer supply pipeline.
[0014] Compared to existing technologies, the advantages of this invention are that, by adopting the above-mentioned solution, the water supply system and fertilizer supply system are integrated into the same main pipeline, and precise coverage of individual plants is achieved through branch pipelines. There is no need to build two systems in parallel, and the amount of pipeline laying is reduced. The drip irrigation nozzle integrates the water spray valve body and the drip irrigation valve body, eliminating the need for manual replacement of the irrigation components. By adjusting the valve core, the flow channel of the valve core can be connected to the first or second flow channel to achieve the effect of underground drip irrigation and top spraying. The flow guide component enables adaptive control of the spraying area, improving the degree of automation and operating efficiency. Furthermore, the detachable connection design of the water spray valve body and the drip irrigation valve body facilitates the maintenance of the drip irrigation nozzle in the later stage, greatly reducing the cost of irrigation equipment.

[0020] like Figures 1-3 As shown, one embodiment of this utility model is a water and fertilizer integrated irrigation system for soft-seed pomegranates, which includes a water supply system 1, a fertilizer supply system 2, a main pipeline 3 and multiple branch pipelines 4. The water supply system 1 and the fertilizer supply system 2 are respectively connected to the main pipeline 3, and the multiple branch pipelines 4 are respectively connected to the main pipeline 3. Each branch pipeline 4 is equipped with a drip irrigation nozzle 5 at its end. The drip irrigation nozzle 5 includes a spray valve body 6, a drip irrigation valve body 7, a valve core 8, a flow guide 9, and an adjusting component 10. The bottom end of the spray valve body 6 is detachably connected to the top end of the drip irrigation valve body 7 via threads. The valve core 8 is rotatably disposed within the spray valve body 6 and the drip irrigation valve body 7. A valve core flow channel 81 is opened on its side wall, and its top end extends outside the spray valve body 6. A first flow channel 61 is opened inside the spray valve body 6, and a water inlet channel 62 is opened on its side wall. A spray section 63 is provided at its top end. The adjusting component 10 is connected to the valve core 8. A second flow channel 71 is opened inside the drip irrigation valve body 7, and a drip irrigation section 72 is provided at its bottom end. The flow guide 9 is sleeved on the end of the valve core 8 that extends outside the spray valve body 6 and corresponds to the spray section 63. The adjusting component 10 is an adjusting knob.
[0021] In use, the input end of each branch pipeline 4 is connected to the main pipeline 3. The number of branch pipelines 4 can be set according to the irrigation area or number of plants. The water inlet channel 62 of the drip irrigation nozzle 5 is connected to the end of the branch pipeline 4. The bottom end of the drip irrigation valve body 7 of the drip irrigation nozzle 5 is inserted into the ground. The adjusting component 10 is rotated to make the valve core flow channel 81 connect with the first flow channel 61 or the second flow channel 71 respectively, so that the spraying part 63 or the drip irrigation part 72 can switch to work to achieve the effect of underground drip irrigation or above-ground spraying.
[0022] This application integrates the water supply system 1 and fertilizer supply system 2 into the same main pipeline 3, and achieves precise coverage of the irrigation area through branch pipelines 4. It eliminates the need to build two systems in parallel, reducing the amount of pipeline laying. The drip irrigation nozzle 5 integrates the water spray valve body 6 and the drip irrigation valve body 7, eliminating the need for manual replacement of the irrigation components. By adjusting the valve core 8 through the adjusting component 10, the effects of underground drip irrigation and top spraying can be achieved. The flow guide component 9 enables adaptive control of the spraying area, improving the degree of automation and operational efficiency. Furthermore, the detachable connection design of the water spray valve body 6 and the drip irrigation valve body 7 facilitates the maintenance of the drip irrigation nozzle 5 in the future, greatly reducing the cost of irrigation equipment.
[0023] In one embodiment, such as Figure 4As shown, a first valve core channel 64 is vertically opened inside the water spray valve body 6, and a water inlet chamber 65 is opened radially and around the first valve core channel 64. A first flow channel 61 is vertically opened on the side wall of the first valve core channel 64. The first flow channel 61 is connected to the water spray part 63, and the water inlet channel 62 is connected to the water inlet chamber 65. Water flows into the water inlet chamber 65 through the water inlet channel 62. When the valve core 8 is rotated to the first side, the valve core flow channel 81 is connected to the first flow channel 61, and the water flows out from the water spray part 63, impacting the guide member 9 to form a range spray.
[0024] In one embodiment, such as Figure 4 As shown, a second valve core channel 73 is vertically opened inside the drip irrigation valve body 7. The second valve core channel 73 is connected to the first valve core channel 64 and is used to install the valve core 8. A second flow channel 71 is vertically opened on the side wall of the second valve core channel 73. The second flow channel 71 is connected to the drip irrigation part 72 and is arranged opposite to the first flow channel 61. When the valve core 8 is rotated to the other side, the valve core flow channel 81 and the first flow channel 61 are closed, and the valve core flow channel 81 and the second flow channel 71 are connected. Water flows through the water inlet chamber 65, the valve core flow channel 81, and the second flow channel 71 and drips out through the drip irrigation part 72.
[0025] In one embodiment, such as Figure 5 As shown, the valve core 8 includes a valve body 83 and a connecting rod 82. The valve body 83 is cylindrical. The valve core flow channel 81 is opened along the axial direction of the valve body 83 on one side of the valve body 83. The connecting rod 82 is located at the top of the valve body 83 and extends to the outside of the spray valve body 6, connecting with the adjusting component 10. When the valve core 8 rotates to one side, the valve core flow channel 81 communicates with the first flow channel 61, and the water flows into the sprinkler irrigation path. When the valve core 8 rotates to the other side, the valve core flow channel 81 communicates with the second flow channel 71, and the water flows into the drip irrigation path. By aligning or misaligning the valve core flow channel 81 with different flow channels, the two irrigation modes can be quickly switched without disassembling or replacing irrigation components, avoiding the cumbersome problem of manually replacing components.
[0026] In one embodiment, such as Figure 2 , Figure 3 As shown, the drip irrigation section 72 is conical in shape, which facilitates insertion into the soil. A spiral flow channel 721 is provided on its outer wall, and a drip irrigation channel 722 is provided inside. The drip irrigation channel 722 is connected to the second flow channel 71. Multiple drip irrigation holes 723 are provided at the bottom of the spiral flow channel 721. The multiple drip irrigation holes 723 are respectively oriented diagonally upward and are respectively connected to the drip irrigation channel 722. The spiral flow channel 721 can avoid clogging by soil particles. At the same time, the drip irrigation holes 723 are oriented diagonally upward, which can avoid clogging when inserted into the soil.
[0027] In one embodiment, such as Figure 4 , Figure 5As shown, the water spraying unit 63 is integrally formed with the top of the water spraying valve body 6, and an annular cavity 631 is provided inside. The annular cavity 631 is connected to the first flow channel 61 to ensure that water and fertilizer are evenly distributed within the annular cavity 631. Multiple water spraying holes 632 are equidistantly opened along the periphery of the top of the water spraying unit 63. In this embodiment, six water spraying holes 632 are used. Each water spraying hole 632 is directly connected to the annular cavity 631, which solves the problem of foliar watering and surface moisture retention of soft-seed pomegranates during hot and dry seasons. In one embodiment, such as Figure 5 As shown, the guide 9 is conical, with its conical surface facing the water spray section 63. A through hole 91 is provided in the middle, and the through hole 91 is slidably connected to the connecting rod 82. The guide 9 can slide along the axial direction of the connecting rod 82 to adapt to different water pressures, thereby automatically adjusting its height.
[0028] When the system water pressure increases, the water jet from the spray section 63 impacts the conical surface of the guide member 9, generating an upward thrust that pushes the guide member 9 to slide upward along the connecting rod 82, increasing the gap between the guide member 9 and the spray section 63 and increasing the spraying distance. When the water pressure decreases, the guide member 9 slides downward under the action of gravity, reducing the gap and decreasing the spraying distance. Different irrigation coverage ranges can be achieved by adjusting the pressure.
[0029] In one embodiment, such as Figure 5 , Figure 6 As shown, a limiting post 811 is provided on one side of the valve body 83, and an arc-shaped limiting groove 74 is provided on the top of the drip irrigation valve body 7 along its radial direction. The limiting post 811 matches and slides with the arc-shaped limiting groove 74 to limit the radial and axial movement of the valve core 8. When the top adjusting component 10 is rotated, the rotation position of the valve core 8 can be sensed by the contact between the two ends of the limiting post 811 and the arc-shaped limiting groove 74. It is also possible to engrave words on the top of the adjusting component 10 or the spray valve body 6 for easy observation and convenient switching between spray irrigation and drip irrigation. At the same time, when the spray valve body 6 and the drip irrigation valve body 7 are connected, the limiting post 811 is located between the limiting groove and the spray valve body 6, which can limit the axial movement of the valve core 8.
[0030] In one embodiment, such as Figure 1 As shown, the water supply system 1 includes a water tower 11, a first valve 12, a first water pump 13, a first pressure gauge 14, a backwash filter 15, a second pressure gauge 16, and a first check valve 17, which are connected in sequence through a water supply pipeline.
[0031] The water supply system 1 provides a purified and stable water source for the system. The backwash filter 15 removes mud, sand and impurities from the water source to prevent clogging of pipelines and drip irrigation nozzles 5. The first pressure gauge 14 detects the water pressure at the front end of the backwash filter 15 and detects the clogging of the backwash filter 15 filter element. Backwashing operations or filter element replacement are performed in a timely manner. The second pressure gauge 16 detects the water pressure of the main pipeline 3 and the first check valve 17 prevents water and fertilizer backflow from contaminating the water source.
[0032] In one embodiment, such as Figure 1 As shown, the fertilizer supply system 2 includes a water-fertilizer tank 21, a second valve 22, a second water pump 23, a third pressure gauge 24, and a second check valve 25, all connected sequentially via fertilizer supply pipelines. Soluble fertilizer is added to the water-fertilizer tank 21 according to a specified ratio and can be stirred until completely dissolved. The water-fertilizer mixture is then pumped into the main pipeline 3 via the second water pump 23, subsequently entering various branch pipelines 4 and being delivered to each drip irrigation nozzle 5. The pressure in the water-fertilizer pipeline is monitored by the third pressure gauge 24, and the backflow of water-fertilizer is prevented by the second check valve 25.
[0033] The integrated water and fertilizer irrigation system for soft-seeded pomegranates also includes a PLC controller. The PLC controller is electrically connected to the first valve 12, the first water pump 13, the first pressure gauge 14, the second valve 22, the second pressure gauge 16, the second water pump 23, and the third pressure gauge 24. In this embodiment, a PLC controller, such as a Siemens S7-200SMART, is used. The controller's output terminals are electrically connected to the first valve 12, the first water pump 13, the second valve 22, and the second water pump 23 to control the start / stop of the components and their operating parameters. The input terminals are connected to the first pressure gauge 14, the second pressure gauge 16, and the third pressure gauge 24 to collect system pressure in real time. The PLC controller can be manually set or call preset programs, such as water and fertilizer parameters for the germination, flowering, and fruit enlargement stages, and automatically adjust the water and fertilizer supply, pressure, and concentration without manual intervention.
[0034] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
