Water-saving intelligent irrigation integrated device

Abstract

This invention provides a water-saving intelligent irrigation integrated device, including a water source filtration and pressure stabilization module, which supplies water to a water-fertilizer mixing module to form a fertigation solution. The fertigation solution is then transported via a distribution pipeline module to an irrigation execution module for irrigation. A soil detection module feeds back monitoring data to a control and communication module, which in turn controls the water-fertilizer mixing module and the irrigation execution module to achieve closed-loop intelligent fertigation. The soil detection module includes a detector and an installation structure. The installation structure drives the detector to move downwards, allowing its probe to insert into the target detection depth. A soil loosening component is located below the detector, pre-loosening the detection area during the downward movement. The soil loosening component promotes rapid and uniform dispersion of water and fertilizer within the detection area, shortening data response time and improving detection accuracy. This device is suitable for fertigation drip irrigation scenarios under alternating irrigation conditions, thereby improving system control efficiency and water-saving and fertilizer-controlling effects.

Description

Technical Field

[0001] This invention relates to the field of irrigation technology, specifically to an integrated water-saving and intelligent irrigation device. Background Technology

[0002] In the field of modern water-saving agriculture and precision irrigation, existing integrated water-saving intelligent irrigation systems typically include core components such as a water source filtration and pressure stabilization module, a water and fertilizer mixing module, a distribution pipeline module, an irrigation execution module, a control and communication module, and a soil monitoring module. These modules work together to achieve water source filtration and pressure stabilization, water and fertilizer ratio mixing, irrigation parameter distribution, and operational status monitoring and control, representing a relatively mature technology in this field. Existing systems are mostly applied to drip irrigation and alternating irrigation systems, using soil moisture sensors or fertility detectors to collect soil moisture content, electrical conductivity, and related nutrient parameters to guide water and fertilizer regulation strategies.

[0003] However, in existing water-saving intelligent irrigation systems, detectors are mostly deployed using direct insertion or fixed methods. There is often a certain degree of spatial difference between the soil microenvironment contacted by the probe and the surrounding irrigated area. During irrigation and fertilization, the diffusion and infiltration rates of water and fertilizer solutions within the detection area are affected by factors such as local soil structure, pore state, and microenvironmental differences. This causes the parameter changes in the detector's micro-area to be asynchronous with the overall changes in the irrigated area, resulting in response lag or insufficient representativeness of the detection data within a certain time period.

[0004] Especially under alternating irrigation or zoned rotation irrigation conditions, when the irrigation intensity, water-fertilizer ratio, or fertilization rhythm is adjusted, the changes in soil moisture content and solution ion concentration near the detection point often cannot quickly reflect the system operation results. The data acquired by the control module has a certain delay, which affects the timing of irrigation strategy correction and the accuracy of dynamic control of fertilizer application, making it difficult to give full play to the advantages of coordinated water and fertilizer scheduling and water-saving management.

[0005] Therefore, a water-saving intelligent irrigation integrated device is provided to address the above problems. Summary of the Invention

[0006] In order to solve the problems of poor safety, uneven heating, moisture retention and lack of active rehabilitation function in existing hot compress devices, and to effectively meet the comprehensive relief and functional improvement needs of patients with chronic knee pain, this invention provides a water-saving intelligent irrigation integrated device.

[0007] The present invention solves the above-mentioned technical problems through the following technical solutions: This invention provides a water-saving intelligent irrigation integrated device, including a water source filtration and pressure stabilization module. The water source filtration and pressure stabilization module supplies water to the water and fertilizer mixing module to form a water and fertilizer solution. The water and fertilizer solution enters the irrigation execution module through the distribution pipeline module to implement irrigation. The soil detection module feeds back the monitoring data to the control and communication module. The control and communication module coordinates and regulates the water and fertilizer mixing module and the irrigation execution module to form a closed-loop irrigation control relationship, thereby realizing intelligent water and fertilizer integrated irrigation. The soil testing module includes a detector and a mounting structure for mounting the detector; the mounting structure is used to drive the detector to move in a direction toward the ground until the probe at the bottom of the detector is inserted to the target soil testing depth. The mounting structure also includes a soil loosening component, which is located below the detector and is used to pre-loosen the soil in the detection area during the detector's downward movement.

[0008] The soil loosening component can loosen the soil in the area to be tested, which is beneficial for the dispersion of irrigation water and fertilizer in the soil. On the one hand, it can detect more accurate data; on the other hand, the accelerated dispersion of water and fertilizer allows for faster data acquisition, thereby determining whether the water and fertilizer meet the requirements during irrigation. It is particularly suitable for drip irrigation with integrated water and fertilizer under alternating irrigation conditions, thereby improving the response speed of the entire intelligent irrigation equipment and enhancing water-saving effects.

[0009] In this technical solution, the installation structure includes a ring-shaped mounting platform, which is set on the ground. A bearing shell is fixed to the top of the mounting platform by fasteners, and the bearing shell is located above the mounting platform. The inner cavity of the support shell is equipped with a lifting component that drives the detector to move up and down. At the bottom of the lifting component is a soil loosening component. The lifting component drives the soil loosening component to operate through a transmission component.

[0010] Several connectors are fixedly installed at the bottom of the mounting platform. These connectors are used to position and fix the mounting platform to the ground.

[0011] Preferably, the connector is an anchor rod, which can be driven into the soil to form an anchor, thereby achieving reliable fixation of the mounting platform.

[0012] In this technical solution, the lifting assembly includes a driving component, which is fixed on the mounting shell at the top of the inner cavity of the bearing shell. The moving end at the bottom of the driving component is fixedly connected to the mounting part, which is used to install the detector. The moving end or mounting part of the drive component is connected to the transmission assembly.

[0013] In this technical solution, the mounting part includes a U-shaped fixed shell, the detector is placed on two placement plates on the inner wall of the fixed shell, and the top of the placement plate is provided with a pressing member that can press down on the top side wall of the detector; The mounting housing is fixed to the drive end of the drive unit via a connecting bracket on its top.

[0014] In this technical solution, the transmission component includes a vertical rack, which is fixed to the mounting part or the moving end of the lifting component by a rod; A drive gear is provided on one side of the vertical rack, which can mesh with it. The drive gear is mounted on the inner wall of the bearing housing via a mounting bracket. The drive gear can rotate on the mounting bracket. Both sides of the drive gear are provided with driven gears fixed coaxially with it. The diameter of the drive gear is smaller than that of the driven gear, and the diameter of the driven gear is at least twice that of the drive gear. A transverse rack is provided on one side of each driven gear, which meshes with it. The transverse rack is slidably connected to the guide housing, which is fixed to the inner wall of the bearing housing. The ends of the two transverse racks penetrate the side wall of the bearing housing and are connected to the soil loosening component.

[0015] Specifically, the vertical rack is fixed to the end of the moving rod on the fixed housing or drive component.

[0016] The horizontal rack is located at the bottom of the driven gear, and the vertical rack is located between the drive gear and the fixed housing.

[0017] A circular shaft is fixed at the center of each of the two circular surfaces of the drive gear, and the circular shaft is sleeved inside the bearing on the mounting bracket. An extension rod is fixed at the center of the outer wall of each of the two cylinders, and the ends of the two extension rods are respectively fixed to the center of the circular surfaces of the two driven gears.

[0018] In this technical solution, the soil loosening component includes a guide part and a soil loosening part. The guide part is fixed on the bearing shell, the bottom of the soil loosening part is buried in the soil, and the soil loosening part is slidably connected to the guide part. The soil loosening part is connected to the transmission assembly. When the lifting assembly moves the detector down, the soil loosening part slides from one side of the guide to the other side through the transmission assembly. When the lifting assembly moves the detector up to reset, the soil loosening part returns to its initial position through the transmission assembly.

[0019] When the transverse rack on the transmission assembly moves, it causes the loosening part to slide on the guide part, thereby achieving soil loosening.

[0020] In this technical solution, the guide part includes two symmetrically arranged bearing horizontal plates. The bearing horizontal plates are located at the bottom of the bearing shell and are fixed to the side wall of the bearing shell by a fourth connecting rod. Two equally symmetrically arranged slide rails are connected between the two bearing horizontal plates. The two slide rails and the two bearing horizontal plates form a rectangular loose soil area. The soil loosening section includes a mounting plate, with both sides of the mounting plate slidably connected to two slide rails, and multiple soil loosening components are fixed at equal intervals at the bottom of the mounting plate. One end of the rectangular frame is fixed to the top of the mounting plate, and the other end of the rectangular frame is connected to the transmission assembly.

[0021] The loosening components are in the form of thin plates or thin rods.

[0022] This technical solution also includes a soil-aggregating component. During the probe insertion process, the soil-aggregating component is used to guide and gather the loosened soil around the probe to improve the contact density between the probe and the surrounding soil and the detection stability.

[0023] By using soil-aggregating components, soil can be slightly focused onto the detector probe, improving the accuracy of structure detection.

[0024] In this technical solution, the soil-gathering component includes at least two symmetrically arranged soil-gathering ends, which are respectively located on both sides of the bottom of the detector; The two soil-collecting ends move down synchronously with the lifting assembly, and the bottom of the soil-collecting ends is inserted into the soil synchronously or sequentially with the probe. After the moving soil-collecting ends pass the limiting part, they move to one side of the detector, thereby pushing the soil to the probe.

[0025] In this technical solution, the soil-gathering end includes a soil-gathering vertical plate, and a guide plate that tilts away from the detector is fixed to the top of the soil-gathering vertical plate. The connecting vertical plate is fixed to the lifting assembly by a telescopic connecting rod. The limiting part includes two limiting units, which correspond to two soil-aggregating vertical plates. Each limiting unit includes a limiting vertical plate, the outer wall of which can overlap with the soil-aggregating vertical plate, meaning the soil-aggregating vertical plate can slide on the limiting vertical plate. The limiting vertical plate is fixed to the bearing shell by a third connecting rod.

[0026] In this technical solution, the detector is used to detect the water and fertilizer content of the soil.

[0027] The detector's signal output is connected to the control and communication components to upload parameters such as soil moisture content, soil salinity, electrical conductivity, and soil temperature to the control and communication components.

[0028] The environmental monitoring component is connected to the control and communication component to provide environmental parameters such as air temperature and humidity, and light intensity.

[0029] Specifically, the control and communication components are electrically connected to the actuators of the water and fertilizer mixing component, the zone control valve, and the irrigation execution component, respectively. They are used to automatically adjust the water and fertilizer ratio, irrigation timing, and irrigation duration based on the parameter data collected by the soil detection component and the environmental monitoring component, thereby forming a water-saving intelligent irrigation closed-loop control system based on soil detection feedback.

[0030] In another implementation, the collection shell is interconnected with individual massage airbags via multi-port tubes, and the massage airbags are interconnected with each other.

[0031] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0032] The positive and progressive effects of this invention are as follows: By incorporating a soil loosening component, the soil in the target detection area can be directionally loosened before testing. This transforms the relatively dense soil layer into a loose structure with higher porosity and permeability, facilitating the uniform dispersion and infiltration of water and fertilizer during irrigation within the detection area. On one hand, soil loosening reduces the impact of locally hardened soil on the probe contact interface, making the moisture, nutrient conductivity, and related parameters collected by the detector closer to the actual soil condition, thus improving the accuracy and reliability of the detection data. On the other hand, accelerating the dispersion process of water and fertilizer within the loosened area significantly shortens the response cycle to data changes, enabling the system to obtain effective feedback results in a shorter time. This allows the system to determine whether the current irrigation and fertilization conditions meet the preset water-fertilizer ratio and crop requirements, making it particularly suitable for integrated water and fertilizer drip irrigation scenarios under alternating irrigation conditions. This improves the response speed and control precision of the entire intelligent irrigation system, further achieving synergistic optimization of water conservation and fertilizer control.

[0035] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0036] like Figure 1 and Figure 2 As shown, the water-saving intelligent irrigation integrated device includes a water source filtration and pressure stabilization module, which supplies water to the water-fertilizer mixing module to form a water-fertilizer solution. The water-fertilizer solution enters the irrigation execution module through the distribution pipeline module to implement irrigation. The soil detection module feeds back the monitoring data to the control and communication module, which then coordinates and regulates the water-fertilizer mixing module and the irrigation execution module to form a closed-loop irrigation control relationship, thereby realizing intelligent water and fertilizer integrated irrigation. The soil testing module includes a detector a and a mounting structure for mounting the detector a; the mounting structure is used to drive the detector a to move in a direction toward the ground until the probe a1 at the bottom of the detector a is inserted to the target soil testing depth; The mounting structure also includes a soil loosening component 6, which is located below the detector a and is used to pre-loosen the soil in the detection area during the downward movement of the detector a.

[0037] Example 1 In this embodiment, the installation structure includes a ring-shaped mounting platform 1, which is set on the ground. The top of the mounting platform 1 is fixed with a bearing shell 2 by a fastener 3, and the bearing shell 2 is located above the mounting platform 1. The inner cavity of the bearing shell 2 is equipped with a lifting assembly 4 that drives the detector a to move up and down. The bottom of the lifting assembly 4 is equipped with a soil loosening assembly 6. The lifting assembly 4 drives the soil loosening assembly 6 to run through the transmission assembly 5.

[0038] The bottom of the mounting platform 1 is fixed with several connectors, which are used to position and fix the mounting platform 1 to the ground.

[0039] Preferably, the connector is an anchor rod 11, which can be driven into the soil to form an anchor, thereby achieving reliable fixation of the mounting platform 1.

[0040] The connector can also be any other structure that can fix the mounting base 1 in place.

[0041] Specifically, the fixing component 3 includes a first vertical rod 31 and a first horizontal rod 32. The first vertical rod 31 and the first horizontal rod 32 are connected to form an "L" structure. The first vertical rod 31 is fixed on the mounting platform 1, and the first horizontal rod 32 is fixed on the bearing shell 2.

[0042] The first vertical rod 31 is telescopic, and a locking device is provided in the telescopic area.

[0043] Example 2 like Figures 6-9 As shown, the lifting assembly 4 includes a drive component 41, which is fixed on the mounting shell 22 at the top of the inner cavity of the bearing shell 2. The movable end at the bottom of the drive component 41 is fixedly connected to the mounting part, which is used to install the detector a. The moving end or mounting part of the drive component 41 is connected to the transmission assembly 5.

[0044] like Figure 10 As shown, the mounting part includes a U-shaped fixed shell 43, and the detector a is placed on two placement plates 431 on the inner wall of the fixed shell 43. The top of the placement plate 431 is provided with a pressing member that can press down on the top side wall of the detector a. The fixed housing 43 is fixed to the drive end of the drive component 41 by the connecting bracket 42 on its top.

[0045] Preferably, the pressing component includes a connecting plate 44, which is fixed on the inner wall of the fixed shell 43. A threaded sleeve is fixed at the center of the connecting plate 44. The threaded sleeve is fitted onto the threaded rod 441, and the threaded rod 441 and the threaded sleeve are connected by threaded engagement. The bottom end of the threaded rod 441 passes through the connecting plate 44 and is connected to the pressing plate 45.

[0046] like Figure 11As shown, preferably, both sides of the lower pressure plate 45 are fixed with moving blocks 451, and the moving blocks 451 are slidably connected in the guide rail 452 arranged vertically, and the guide rail 452 is fixed on the inner wall of the fixed shell 43. The threaded rod 441 can rotate on the lower pressure plate 45.

[0047] The detector a is placed on the placement plate 431 of the fixed shell 43 through the operation window 21 on the carrier shell 2, so that the probe a1 at the bottom of the detector a extends into the through groove at the bottom of the fixed shell 43. Then, the threaded rod 441 is rotated. Under the push of the meshing thread, the threaded rod 441 drives the lower pressure plate 45 to move down until the lower pressure plate 45 presses against the top surface of the detector a, thereby completing the installation of the detector a.

[0048] The drive element 41 is preferably one of an electric actuator, a pneumatic actuator, or a hydraulic actuator.

[0049] The drive component 41 extends or shortens, and through the connecting frame 42, it drives the fixed shell 43 to move vertically, thereby driving the detector a to move vertically.

[0050] Example 3 like Figures 7-10 As shown, the transmission assembly 5 includes a vertical rack 51, which is fixed to the mounting part or the moving end of the lifting assembly 4 by a rod. A drive gear 53 is provided on one side of the vertical rack 51, which can mesh with it. The drive gear 53 is mounted on the inner wall of the bearing shell 2 through the mounting bracket 54. The drive gear 53 can rotate on the mounting bracket 54. Both sides of the drive gear 53 are provided with driven gears 55 that are fixed coaxially with it. The diameter of the drive gear 53 is smaller than that of the driven gear 55, and the diameter of the driven gear 55 is at least twice the diameter of the drive gear 53. A transverse rack 56 is provided on one side of each driven gear 55, which meshes with it. The transverse rack 56 is slidably connected to the guide shell 57, which is fixed on the inner wall of the bearing shell 2. The ends of the two transverse racks 56 penetrate the side wall of the bearing shell 2 and are connected to the soil loosening component 6.

[0051] The guide shell 57 is fixed to the side wall of the bearing shell 2 by the first connecting rod 571.

[0052] Specifically, the vertical rack 51 is fixed to the end of the moving rod on the fixed housing 43 or the driving member 41.

[0053] The transverse rack 56 is located at the bottom of the driven gear 55, and the vertical rack 51 is located between the drive gear 53 and the fixed housing 43.

[0054] A round shaft is fixed at the center of each of the two circular surfaces of the drive gear 53, and the round shaft is sleeved inside the bearing on the mounting bracket 54. An extension rod 52 is fixed at the center of the outer wall of each of the two cylinders, and the ends of the two extension rods 52 are respectively fixed to the center of the circular surfaces of the two driven gears 55.

[0055] When the driving component 41 moves the fixed housing 43 downward, the vertical rack 51 moves downward synchronously with the fixed housing 43 and the detector a. The moving vertical rack 51 begins to engage with the driving gear 53, thereby driving the driving gear 53 to rotate. The driving gear 53 drives the driven gear 55 to rotate through the extension rod 52. The driven gear 55 drives the transverse rack 56 that meshes with it to move, thereby driving the soil loosening component 6 to run.

[0056] After the vertical rack 51 disengages from the drive gear 53, the fixed housing 43 continues to move downward until the probe a1 on the detector a is inserted into the soil.

[0057] Example 4 like Figures 7-9 As shown, the soil loosening component 6 includes a guide part and a soil loosening part. The guide part is fixed on the bearing shell 2, the bottom of the soil loosening part is buried in the soil, and the soil loosening part is slidably connected to the guide part. The soil loosening part is connected to the transmission component 5. When the lifting component 4 moves the detector a down, the soil loosening part slides from one side of the guide to the other side through the transmission component 5. When the lifting component 4 moves the detector a up to reset, the soil loosening part returns to the initial position through the transmission component 5.

[0058] When the transverse rack 56 on the transmission assembly 5 moves, it drives the loosening part to slide on the guide part, thereby achieving soil loosening.

[0059] The guide section includes two symmetrically arranged bearing plates 61. The bearing plates 61 are located at the bottom of the bearing shell 2 and are fixed to the side wall of the bearing shell 2 by a fourth connecting rod 611. Two equally symmetrically arranged slide rails 62 are connected between the two bearing plates 61. The two slide rails 62 and the two bearing plates 61 form a rectangular loose soil area. The soil loosening section includes a mounting plate 63, with both sides of the mounting plate 63 slidably connected to two slide rails 62, and a plurality of soil loosening components 64 arranged at equal intervals fixed at the bottom of the mounting plate 63. One end of the rectangular frame is fixed to the top of the mounting plate 63, and the other end of the rectangular frame is connected to the transmission assembly 5.

[0060] The loosening component 64 is in the form of a thin plate or a thin rod.

[0061] The rectangular frame includes two parallel transmission rods 66. The two ends of the two transmission rods 66 are fixed to the first connecting plate 65 and the second connecting plate 67, respectively. The first connecting plate 65 is fixedly connected to the mounting plate 63 through the second connecting rod 651. A fixing rod 68 is fixed on the second connecting plate 67. The fixing rod 68 is fixed to the connecting frame 69. The connecting frame 69 is connected to the ends of the two driven racks.

[0062] The connecting frame 69 is preferably triangular, and its three pointed areas are respectively fixedly connected to the fixed rod 68 and the two driven racks.

[0063] The moving transverse rack 56 drives the rectangular frame to move through the connecting frame 69, thereby fixing the mounting plate 63 on the slide rail 62. The soil loosening component 64 in the soil also moves accordingly, thus completing the loosening of the soil in the area to be tested.

[0064] When the drive rack moves upward with the mounting housing 22, the drive rack drives the drive gear 53 to rotate in the opposite direction, thereby driving the transverse rack 56 to rotate in the opposite direction, and driving the mounting plate 63 and the loosening component 64 to reset.

[0065] Example 5 It also includes a soil-aggregating component 8, which is used to guide and gather the loosened soil around the probe a1 during the insertion of the probe a1 into the soil, so as to improve the contact density between the probe a1 and the surrounding soil and the detection stability.

[0066] By setting up the soil-aggregating component 8, during the insertion of the detector a and probe a1 into the soil, the loose soil is moderately aggregated and compressed to the periphery of probe a1, so that probe a1 and the surrounding soil form a stable contact interface, thereby avoiding measurement drift problems caused by local voids or soil dispersion. By enhancing the coupling stability between probe a1 and representative soil samples in the detection area, the data consistency and measurement accuracy of the detection structure under long-term and multiple measurement conditions can be effectively improved.

[0067] like Figure 7 and 8 As shown, the soil-gathering component 8 includes at least two symmetrically arranged soil-gathering ends, which are respectively located on both sides of the bottom of the detector a; The two soil-collecting ends move down synchronously with the lifting component 4, and the bottom of the soil-collecting ends is inserted into the soil synchronously or sequentially with the probe a1. After the moving soil-collecting ends pass the limiting part 7, they move to one side of the detector a, thereby pushing the soil to the probe a1.

[0068] Furthermore, the soil-gathering end has two or four.

[0069] The soil-gathering end includes a soil-gathering vertical plate 81, and a guide plate 82 that is inclined toward the side away from the detector a is fixed on the top of the soil-gathering vertical plate 81. The connecting vertical plate is fixed to the lifting assembly 4 by a telescopic connecting rod 83. The limiting part 7 includes two limiting units, which correspond to two soil-aggregating vertical plates 81. Each limiting unit includes a limiting vertical plate 71. The outer wall of the limiting vertical plate 71 can overlap with the soil-aggregating vertical plate 81, that is, the soil-aggregating vertical plate 81 can slide on the limiting vertical plate 71. The limiting vertical plate 71 is fixed to the bearing shell 2 by the third connecting rod 72.

[0070] Specifically, the connecting rod 83 consists of a horizontal bar and a vertical bar. The second horizontal bar and the second vertical bar are connected to form an "L"-shaped structure. The second vertical bar is fixed on the outer wall of the fixed shell 43, and the second horizontal bar is fixed on the limiting vertical plate 71. The second horizontal bar is telescopic, and a spring is sleeved on the surface of the second horizontal bar. The two ends of the spring are respectively fixed to the two ends of the second horizontal bar. The spring is used for reset.

[0071] The top of the overlap between the limiting vertical plate 71 and the guide inclined plate 82 is rounded or equipped with guide wheels. At the same time, the angle between the guide inclined plate 82 and the vertical plate does not exceed 10° to avoid self-locking of the inclined surface.

[0072] The soil-aggregating vertical plate 81 moves downward along with the fixed shell 43 on the lifting assembly 4. During the downward movement, the soil-aggregating vertical plate 81 first slides and overlaps with the limiting vertical plate 71. As it continues to move downward, both the soil-aggregating vertical plate 81 and the probe a1 are inserted into the soil until the guide inclined plate 82 at the top of the soil-aggregating vertical plate 81 overlaps with the top of the limiting vertical plate 71. Under the push of the inclined surface of the guide inclined plate 82, the soil-aggregating vertical plate 81 moves towards the side of the fixed shell 43 and the detector a. The second crossbar shortens, the spring is compressed, thereby pushing the soil towards the side of the probe a1 under the detector a, achieving the soil-aggregating effect.

[0073] Example 6 The water source filtration and pressure stabilization module's outlet is connected to the water inlet of the water-fertilizer mixing module, the water-fertilizer mixing module's liquid outlet is connected to the distribution pipeline module, and the distribution pipeline module is connected to the irrigation execution module via a zone control valve, used to transport the mixed water-fertilizer solution to the crop root zone soil.

[0074] Detector a is used to detect the water and fertilizer content of the soil. Specifically, it is a soil moisture sensor and a fertilizer detection sensor. The fertilizer detection sensor is preferably one of a conductivity-type fertility detector a, an ion-selective electrode-type detector a, and a spectral / colorimetric sensor a.

[0075] Preferably, two detectors a for detecting water and fertilizer are placed simultaneously on the fixed shell 43.

[0076] The signal output terminal of the soil moisture sensor is connected to the control and communication component to upload parameters such as soil moisture content, soil salinity, electrical conductivity, and soil temperature to the control and communication component.

[0077] The environmental monitoring component is connected to the control and communication component to provide environmental parameters such as air temperature and humidity, and light intensity.

[0078] The control and communication module is electrically connected to the actuators of the water and fertilizer mixing module, the zone control valve, and the irrigation execution module, respectively. It is used to automatically adjust the water and fertilizer ratio, irrigation timing, and irrigation duration based on the parameter data collected by the soil detection module and the environmental monitoring module, thereby forming a water-saving intelligent irrigation closed-loop control system based on soil detection feedback.
