Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural irrigation equipment, in particular to a remote control automatic irrigation device. BACKGROUND

[0002] Smart agriculture is an important force in the process of modern agriculture and the direction of future global agricultural development. China is vigorously promoting the application of modern information technology such as Internet of Things, cloud computing, big data and mobile Internet in modern agriculture, promoting the upgrading of the entire agricultural industry chain, improving the level of agricultural technology and informatization, and promoting the transformation from a large agricultural country to a powerful agricultural country. With the increasing scarcity of global water resources, countries around the world are actively exploring effective water-saving approaches and measures. The level of automatic control water-saving irrigation technology represents the development status of agricultural modernization. The low level of automation of irrigation systems is the main reason for the development of efficient agriculture.

[0003] At present, agricultural plants are planted according to planting areas. Due to the reasons of light time and angle, the water content of the soil in different planting areas is different. Based on the above description, the present inventor found that the existing irrigation device mainly has the following deficiencies, such as: according to the water content of the soil in different planting areas, it is difficult to adapt to directional irrigation, thereby causing excessive irrigation and excessive waste of water resources. SUMMARY

[0004] The present application provides a remote control automatic irrigation device, which can conveniently adapt to directional irrigation according to the water content of the soil in different planting areas.

[0005] The remote control automatic irrigation device provided by the present application adopts the following technical scheme:

[0006] A remote control automatic irrigation device, comprising a remote terminal and a water pump, the remote terminal is used for remotely controlling the switch of the water pump, the input end of the water pump is connected with an external water source, the input end of the water pump is connected with a main pipe, a plurality of branch pipes are arranged on the main pipe and are in communication with the main pipe, a plurality of irrigation assemblies are arranged on the branch pipes;

[0007] The irrigation assembly comprises a vertical pipe connected to the branch pipe, an installation ball is arranged on the vertical pipe and close to the bottom of the vertical pipe, the inside of the installation ball is hollow, and a soft rubber tube in communication with the installation ball is arranged on the outer surface of the installation ball, a plurality of soft rubber tubes are arranged, the plurality of soft rubber tubes form a root-like structure on the outer surface of the installation ball, and the root-like structure and the branch pipe are buried in the soil;

[0008] The surface of the flexible rubber tube is equipped with several soil moisture sensors for real-time monitoring of soil moisture content. The signal output terminal of the soil moisture sensor is connected to a controller. When the soil moisture content is lower than a set threshold, the controller controls the opening and closing of the solenoid valve installed on the branch pipe, so that the branch pipe is connected to the main pipe.

[0009] By adopting the above technical solution, when the soil moisture sensor detects that the soil moisture is lower than the set threshold, the controller controls the opening and closing state of the solenoid valve through the remote terminal, thereby connecting the branch pipe at that location to the main pipe and starting the water pump for irrigation. By monitoring the soil moisture in real time and performing precise irrigation control according to needs, and by controlling the solenoid valve through the controller, the corresponding branch pipes can be used to irrigate the soil in different planting areas in a targeted manner, which can effectively save water resources and avoid excessive waste.

[0010] Preferably, the riser is equipped with a water injection pipe inside, and the water injection pipe is made of a flexible material.

[0011] By adopting the above technical solution, and by using a flexible material for the water injection pipe, a more flexible and convenient water injection effect is achieved. Therefore, it can adapt to risers of different shapes and sizes, improving the convenience of operation and water injection.

[0012] Preferably, the top of the riser is provided with an extension pipe, and the bottom of the extension pipe and the top of the riser are connected by a flexible corrugated pipe. The water injection pipe passes through the interior of the riser, the corrugated pipe and the extension pipe from bottom to top. Several air inflator pipes are provided between the outer wall of the water injection pipe and the inner wall of the corrugated pipe. The top of the air inflator pipe is closed, and the bottom of the air inflator pipe is connected to an air pump. The power supply of the air pump is electrically connected to the output terminal of the controller.

[0013] By employing the above technical solution, the state of the extension tube is adjusted by controlling the expansion and degassing of the air inflator, thus simulating the wilting of plant stems under water shortage. The design principle is to control the operation of the air pump by monitoring the soil moisture content, thereby controlling the state of the air inflator and affecting the shape of the extension tube. When the soil moisture content is higher than a set threshold, the controller sends a signal to the air pump via electrical connection, causing it to inject gas into the air inflator, which expands and provides some support. In this way, the riser, corrugated pipe, and extension tube are all on the same vertical plane and are upright. When the soil moisture content is lower than the set threshold, the controller sends a signal to the air pump via electrical connection, causing it to expel the gas from the air inflator. The air inflator is in a gas-free state, the support disappears, and the extension tube bends at the position of the corrugated pipe under the action of gravity, drooping, simulating the wilting effect of plant stems under water shortage.

[0014] Preferably, a sponge block is filled between the water injection pipe and the corrugated pipe, and the air inflator penetrates the interior of the sponge block.

[0015] By adopting the above technical solution, the expanded air tube compresses the porous sponge inside the sponge block, which to a certain extent restricts the deformation of the air tube, making the deformation of the air tube more stable and less prone to over-expansion.

[0016] Preferably, the outer surface of the corrugated pipe is provided with a plurality of rubber rings along the longitudinal direction, and the inside of the rubber rings is provided with an annular cavity, and a heating element is provided in the annular cavity of the rubber rings.

[0017] By adopting the above technical solution, a heating element is installed inside the rubber ring. When the outside temperature is below 0 degrees Celsius, the heating element can heat the bellows to prevent water from freezing inside the water injection pipe. The controller controls the heating of the heating element to keep the temperature of the water injection pipe within a range that is not prone to freezing, ensuring smooth water flow.

[0018] Preferably, the top of the extended pipe is provided with a mounting base, the inside of the mounting base is provided with a nozzle assembly, the nozzle assembly is connected to the water injection pipe, and the inside of the mounting base is provided with a bearing, the nozzle assembly is rotatably mounted in the bearing.

[0019] By adopting the above technical solution, and by setting a rotatable nozzle assembly inside the bearing, a larger range of rotation can be achieved, covering a wider watering area; this is especially important for large botanical gardens, farmland, or lawns.

[0020] Preferably, the extended tube has an internal drug delivery tube, and there are several drug delivery tubes.

[0021] By adopting the above technical solution, the medicine in the dosing tube and the water in the water injection tube are mixed and then enter the interior of the nozzle assembly, and are sprayed out through the nozzle assembly to achieve the function of irrigation.

[0022] Preferably, the nozzle assembly includes a nozzle inner core and a water inlet sleeve disposed at the bottom of the nozzle inner core, the water inlet sleeve rotating inside the bearing, and an impeller disposed at the bottom of the water inlet sleeve.

[0023] By adopting the above technical solution, the impeller can increase the speed and pressure of water through rotation. When water passes through the impeller, the rotation of the impeller pushes the water into the nozzle core, increasing the water pressure and making the water flow stronger. This helps to achieve spraying and irrigation over a longer distance, ensuring that the water flow can cover the plants or areas that need irrigation.

[0024] Preferably, the drug delivery tube has a spiral structure, and the liquid outlet end of the drug delivery tube is inclined toward the surface of the impeller.

[0025] By adopting the above technical solution, the force can be easily transferred to the impeller by the impact of the liquid ejected from the dosing tube, thereby generating a rotational torque and causing the impeller to start rotating. This design of the rotating impeller can convert the power of the liquid into mechanical energy, improving the working efficiency of the equipment; on the other hand, it accelerates the mixing between the liquid medicine and water.

[0026] Preferably, the nozzle core has a first spray channel and a second spray channel inside, the upper surface of the nozzle core has a plurality of first spray holes that communicate with the first spray channel, the first spray holes of the nozzle core have a jet head inside, the radial surface of the nozzle core has a plurality of spray guide grooves, and the bottom of the spray guide grooves has a second spray hole that communicates with the second spray channel.

[0027] By adopting the above technical solution, the water sprayed through the first spray channel can effectively expand the longitudinal diffusion range of the spray particles, and the water sprayed through the guide channel and the second spray channel can effectively expand the horizontal diffusion range of the spray particles, thereby improving the irrigation effect.

[0028] In summary, this application has the following beneficial effects:

[0029] 1. When the soil moisture sensor detects that the soil moisture is lower than the set threshold, the controller controls the on / off state of the solenoid valve through the remote terminal, thereby connecting the branch pipe at that location to the main pipe and starting the water pump for irrigation. By monitoring the soil moisture in real time and performing precise irrigation control according to needs, and by controlling the solenoid valve through the controller, the corresponding branch pipes can be used to irrigate the soil in different planting areas in a targeted manner, which can effectively save water resources and avoid excessive waste.

[0030] 2. The extension tube's state is adjusted by controlling the expansion and degassing of the air inflator to simulate the wilting of plant stems under water shortage. The design principle is to control the air pump's operation by monitoring the soil moisture content, thereby controlling the state of the air inflator and influencing the extension tube's shape. When the soil moisture content is higher than a set threshold, the controller sends a signal to the air pump via electrical connection, causing it to inject gas into the air inflator, expanding it and providing some support. In this way, the riser, corrugated pipe, and extension tube are all on the same vertical plane, in an upright state. When the soil moisture content is lower than the set threshold, the controller sends a signal to the air pump via electrical connection, causing it to expel the gas from the air inflator. The air inflator is in a gas-free state, the support disappears, and the extension tube bends at the corrugated pipe position under gravity, drooping, simulating the wilting effect of a plant stem under water shortage.

[0031] 3. By installing a heating element inside the rubber ring, when the outside temperature is below 0 degrees Celsius, the heating element can heat the bellows to prevent water from freezing inside the water injection pipe; the controller controls the heating of the heating element to keep the temperature of the water injection pipe within a range that is not prone to freezing, ensuring smooth water flow.

[0032] 4. The water sprayed through the first spray channel can effectively expand the longitudinal diffusion range of the spray particles, and the water sprayed through the guide channel and the second spray channel can effectively expand the horizontal diffusion range of the spray particles, thereby improving the irrigation effect.

[0045] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0046] This invention discloses a remote-controlled automatic irrigation device, such as... Figure 1 As shown, the system includes a remote terminal and a water pump. The remote terminal is used to remotely control the water pump's on / off state. The water pump's input end is connected to an external water source and a main pipe 1. The main pipe 1 has several branch pipes 2 connected to it, and each branch pipe 2 has several irrigation components 3. These irrigation components 3 are evenly distributed within the planting area. Specifically, by controlling the water pump's on / off state through the remote terminal, the water pump can be turned on or off, thereby controlling the water flow into the main pipe 1 and its branch pipes 2. Finally, the irrigation components 3 irrigate the planting area. By controlling the water pump's on / off state through the remote terminal, the grower can adjust the irrigation system's operating status at any time according to actual needs without having to personally go to the planting area to operate it.

[0047] like Figure 1As shown, the irrigation component 3 includes a riser 301, which is made of rigid high-density polyethylene. The bottom of the riser 301 is vertically connected to the branch pipe 2. The riser 301 and the branch pipe 2 are connected and fixed by a flange 302. By using the flange 302, a strong connection is formed between the riser 301 and the branch pipe 2, improving the overall strength and stability of the system. This ensures that the riser 301 and the branch pipe 2 will not loosen or fall off when the water pressure is high. Using the flange 302 connection makes it relatively easy to disassemble and replace the connection between the riser 301 and the branch pipe 2. When maintenance or replacement of the branch pipe 2 is required, simply open the flange 302 connection, remove the original branch pipe 2, and install the new branch pipe 2. No large-scale modification to the riser 301 is required. Furthermore, the flange 302 has a rubber gasket inside to provide good sealing, which can effectively prevent water leakage or seepage, thereby reducing water waste.

[0048] like Figure 1 and Figure 2 As shown, a mounting ball 4 is provided on the riser 301 near its bottom. The mounting ball 4 is hollow inside, and a flexible rubber tube 5 is connected to its outer surface. The flexible rubber tube 5 is made of flexible polyvinyl chloride. Several flexible rubber tubes 5 are provided, forming a root-like structure on the outer surface of the mounting ball 4. This root-like structure and the branch tube 2 are buried inside the soil. The root-like structure allows the flexible rubber tube 5 to make better contact with the soil, increasing the contact area with the soil. This can improve the sensor's ability to sense soil moisture and more accurately detect the soil moisture content. In addition, the root-like structure simulates the distribution of plant roots in the soil, which can better simulate the process of plant water absorption. The flexible rubber tube 5 can absorb soil moisture more effectively through the root-like structure, providing more reliable soil moisture data. Since the root-like structure is distributed deep in the soil, it can cover a larger range of moisture gradients. This allows the soil moisture sensor 6 to provide more comprehensive and representative soil moisture information, helping farmers or horticulturalists to better understand the distribution of soil moisture.

[0049] like Figure 1 and Figure 2As shown, the surface of the flexible rubber hose 5 is equipped with several soil moisture sensors 6 for real-time monitoring of soil moisture content. The signal output terminals of the soil moisture sensors 6 are connected to a controller, which is located inside the mounting ball 4. When the soil moisture content is lower than a set threshold, the controller controls the opening and closing of the solenoid valve 7 on the branch pipe 2, so that the corresponding branch pipe 2 is connected to the main pipe 1. By monitoring soil moisture in real time and irrigating as needed, over-irrigation and waste can be avoided. Irrigation will only be carried out when the soil moisture content is lower than the set threshold, effectively utilizing water resources. By installing the soil moisture sensors 6 and the controller, automated irrigation control can be achieved. No manual intervention is required; the system automatically determines whether irrigation is needed based on soil moisture, improving the efficiency and accuracy of irrigation. The controller controls the solenoid valve 7, allowing the corresponding branch pipe 2 to irrigate the soil in different planting areas in a targeted manner, effectively saving water resources and avoiding excessive waste. Timely irrigation can maintain suitable soil moisture, which is conducive to the normal growth and development of plants. By irrigating as needed, the adverse effects of soil drought or over-watering on plant growth can be avoided, improving the survival rate and growth quality of plants.

[0050] like Figure 3 As shown, the riser 301 is equipped with a water injection pipe 303 inside. The central axis of the water injection pipe 303 coincides with the central axis of the riser 301. The water injection pipe 303 is made of flexible PVC. The flexible PVC water injection pipe 303 has good flexibility and plasticity and can adapt to risers 301 of different shapes and sizes. It can be bent freely according to the bending and deformation of the riser 301, so as to better adapt to different irrigation systems, soil structures and root layouts.

[0051] like Figure 3 As shown, the top of the riser 301 is provided with an extension pipe 304. The bottom of the extension pipe 304 and the top of the riser 301 are connected by a flexible corrugated pipe 305. The water injection pipe 303 passes through the interior of the riser 301, the corrugated pipe 305 and the extension pipe 304 from bottom to top. Several air inflator pipes 8 are provided between the outer wall of the water injection pipe 303 and the inner wall of the corrugated pipe 305. The top of the air inflator pipe 8 is closed. The bottom of the air inflator pipe 8 is connected to an air pump 9. The power supply of the air pump 9 is electrically connected to the output terminal of the controller.

[0052] like Figure 3 As shown, when the controller detects that the soil moisture content is higher than the set threshold, the air pump 9 is used to inject gas into the air inflator 8, so that the air inflator 8 is in an expanded state and has a certain supporting force, so that the riser 301, the corrugated pipe 305 and the extension pipe 304 are on the same vertical plane.

[0053] like Figure 3As shown, when the controller detects that the soil moisture content is lower than the set threshold, the air pump 9 causes the gas inside the air tube 8 to be discharged, the supporting force to disappear, and the extension tube 304 bends at the position of the corrugated tube 305 under the action of gravity. At this time, the extension tube 304 is in a drooping state, simulating the wilting effect of plant stems in a water-deficient state, which is used to remind that the soil moisture content is in a water-deficient state. The above structure adjusts the state of the extension tube 304 by controlling the expansion and degassing of the air tube 8 to simulate the wilting effect of plant stems in a water-deficient state. The design principle is to control the operation of the air pump 9 by monitoring the soil moisture content, thereby controlling the state of the air tube 8, which in turn affects the shape of the extension tube 304.

[0054] like Figure 3 As shown, the advantage of this design is that by changing the state of the extended tube 304, it simulates the wilting effect of a plant stem in a water-deficient state, intuitively indicating the state of soil moisture content and helping farmers or gardening enthusiasts judge the soil moisture condition; once the extended tube 304 is in a drooping state, it means that the soil is short of water and timely irrigation is required.

[0055] like Figure 2 , Figure 3 and Figure 4 As shown, further, when the controller detects that the soil moisture content is lower than the set threshold, the air pump 9 causes the gas inside the air pipe 8 to be discharged, the supporting force to disappear, and the extension pipe 304 to bend 180° at the position of the corrugated pipe 305 under the action of gravity. At this time, the top outlet of the extension pipe 304 faces downward. After the corrugated pipe 305 bends, the water injection pipe 303 bends and is squeezed to discharge the water accumulated in the water injection pipe 303 and located at the position of the extension pipe 304, so as to prevent the water from being stored in the extension pipe 304 for a long time and deteriorating.

[0056] like Figure 3 and Figure 5 As shown, specifically, the air inflator 8 is evenly distributed at equal angles around the central axis of the water injection pipe 303. The even distribution of the air inflator 8 can ensure that uniform pressure is generated around the water injection pipe 303. This can avoid local excessively high or low pressure and ensure that the squeezing pressure of the water injection pipe 303 is evenly distributed. The bottom of the air inflator 8 is connected to the annular support pipe 10. The annular support pipe 10 is connected to the output end of the air pump 9. The connection between the annular support pipe 10 and the air pump 9 can provide stable support force, so that the air inflator 8 can maintain an appropriate inflation state.

[0057] like Figure 3 and Figure 5As shown, a sponge block 11 is filled between the outer wall of the water injection pipe 303 and the inner wall of the corrugated pipe 305. The air inflator 8 passes through the interior of the sponge block 11. The sponge block 11 is made of porous sponge. After the air inflator 8 expands, the porous sponge inside the sponge block 11 is in a compressed state, which to a certain extent restricts the deformation of the air inflator 8, making the deformation of the air inflator 8 more stable and less prone to excessive expansion. Moreover, the sponge block 11 has a good buffering effect, which can effectively prevent wear between the air inflator 8 and the inner wall of the corrugated pipe 305, and plays a role in protecting the air inflator 8.

[0058] like Figure 3 and Figure 5 As shown, further, rubber rings 12 are evenly spaced along the longitudinal direction on the outer surface of the corrugated pipe 305. An annular cavity is provided inside the rubber ring 12, and a heating element is installed within the annular cavity of the rubber ring 12. The heating element is used to heat the corrugated pipe 305 body. Specifically, the heating element is an annular heating wire. When the external temperature is below 0 degrees Celsius, a temperature sensor installed on the riser 301 detects the external temperature information and transmits the detected temperature information to the controller. The controller controls the heating element to heat the water and transfers the heat to the inside of the water injection pipe 303. When the external temperature is below 0 degrees Celsius, the heating element can heat the corrugated pipe 305 to prevent water from freezing inside the water injection pipe 303. By controlling the heating element through the controller, the temperature of the water injection pipe 303 is kept within a range that prevents freezing, ensuring smooth water flow.

[0059] like Figure 6 , Figure 7 and Figure 8 As shown, the top of the extended pipe 304 is provided with a mounting base 306, and the nozzle assembly 13 is provided inside the mounting base 306. The nozzle assembly 13 is connected to the water injection pipe 303. The mounting base 306 is provided with a bearing 14, and the nozzle assembly 13 is rotatably mounted in the bearing 14. The nozzle assembly 13 can rotate within the bearing 14, which can achieve a larger range of rotation and cover a wider watering area. This is especially important for large areas such as botanical gardens, farmland, or lawns. In addition, the bearing 14 not only supports the rotation of the nozzle assembly 13, but also reduces frictional wear during rotation and extends the service life of the nozzle.

[0060] like Figure 8As shown, the extended pipe 304 has several drug delivery pipes 15 inside. These drug delivery pipes 15 are located in the space between the inner wall of the extended pipe 304 and the outer wall of the water injection pipe 303. The drug solution in the drug delivery pipe 15 mixes with the water in the water injection pipe 303 and enters the interior of the nozzle assembly 13, where it is sprayed out to irrigate. The placement of the drug delivery pipes 15 in the space between the inner wall of the extended pipe 304 and the outer wall of the water injection pipe 303 ensures that the drug solution and water are mixed evenly, guaranteeing that the drug solution is evenly distributed in the water flow. In this way, while the nozzle assembly 13 is spraying water, the drug solution is also evenly sprayed onto the plants. Even application of the drug can effectively prevent and treat plant diseases and pests, improve the plant's disease resistance, and promote healthy plant growth.

[0061] like Figure 8 and Figure 9 As shown, the nozzle assembly 13 includes a nozzle inner core 1301 and a water inlet sleeve 1302 disposed at the bottom of the nozzle inner core 1301. The water inlet sleeve 1302 rotates inside the bearing 14. An impeller 1303 is provided at the bottom of the water inlet sleeve 1302. The impeller 1303 at the bottom of the water inlet sleeve 1302 can increase the speed and pressure of the water through rotation. When water passes through the impeller 1303, the rotation of the impeller 1303 pushes the water into the nozzle inner core 1301, increasing the water pressure and making the water flow stronger. This helps to achieve spraying and irrigation over a longer distance, ensuring that the water flow can cover the plants or areas that need irrigation.

[0062] like Figure 8 and Figure 9 As shown, the drug delivery tube 15 has a spiral structure, and the liquid outlet end of the drug delivery tube 15 is inclined towards the surface of the impeller 1303. By utilizing the impact of the liquid ejected from the drug delivery tube 15 on the impeller 1303, the force can be easily transmitted to the impeller 1303, thereby generating a rotational torque and causing the impeller 1303 to start rotating. This design of rotating impeller 1303 can convert the power of the liquid into mechanical energy, improving the working efficiency of the equipment; on the other hand, it accelerates the mixing between the drug solution and water.

[0063] like Figure 9 and Figure 10As shown, the nozzle core 1301 has a conical lotus-shaped structure that expands at the top and narrows at the bottom. The nozzle core 1301 has a first spray channel inside, and its upper surface has several first spray holes 1304 that communicate with the first spray channel. Each first spray hole 1304 contains a jetting head 1305. A portion of the mixed medication enters the first spray channel through the water inlet sleeve 1302 and passes through the jetting head 1305 within the first spray hole 1304. Due to the conical lotus-shaped structure of the nozzle core 1301, and the first spray holes 1304 and jetting head 1305, the sprayed medication can form a fine mist that sprays upwards, effectively expanding the longitudinal diffusion range of the spray particles. These fine spray particles are better absorbed and spread by the air, thereby improving the absorption efficiency and efficacy of the medication.

[0064] like Figure 9 and Figure 10 As shown, the inner core 1301 of the nozzle has a second spray channel inside, and a plurality of spray guide grooves 1306 are provided on the radial surface of the inner core 1301. The bottom of the spray guide grooves 1306 is provided with a second spray hole 1307. The second spray channel is connected to the second spray hole 1307. The other part of the mixed medicine enters the second spray channel through the water inlet sleeve 1302 and passes through the interior of the second spray hole 1307. With the centrifugal rotation of the inner core 1301 of the nozzle, the medicine is pushed by centrifugal force and sprayed out from the bottom of the spray guide groove 1306. In this way, the medicine will cover a larger area in the horizontal direction by centrifugal spraying, which can effectively expand the diffusion range of the spray particles in the horizontal direction, thereby improving the treatment effect.

[0065] like Figure 10 As shown, specifically, the spray guide channel 1306 has an arc-shaped structure, and the cross-sectional dimensions of the spray guide channel 1306 decrease uniformly from bottom to top. The second spray hole 1307 is located at the maximum cross-sectional position of the spray guide channel 1306. The uniform decrease in cross-sectional dimensions of the spray guide channel 1306 from bottom to top causes the liquid medicine to gradually accelerate during the flow process. When the liquid medicine reaches the maximum cross-sectional position of the spray guide channel 1306, the spray speed will reach its maximum. The second spray hole 1307 is located at the maximum cross-sectional position of the spray guide channel 1306. This design ensures that the liquid medicine is sprayed out under the optimal spray conditions, thereby improving spray accuracy and hit rate. It can also effectively increase the horizontal spray distance, allowing the liquid medicine to reach a farther target area, improving the coverage and effect of treatment.

[0066] like Figure 11As shown, the mounting base 306 has a regular hexagonal structure. Six sets of mounting bases 306 are provided on the upper surface of the mounting base 306. Each of the six sets of mounting bases 306 has a rotating shaft, and a protective plate 16 is mounted on the rotating shaft. All six protective plates 16 have a petal-shaped structure. When the six protective plates 16 rotate relative to each other to a closed state, they form a flower bud-like structure, which wraps around the outside of the nozzle inner core 1301. The protective plates 16 can wrap around the outside of the nozzle inner core 1301, providing a physical barrier protection and effectively preventing the nozzle inner core 1301 from being subjected to external impacts, collisions, or other mechanical damage. This helps to extend the service life of the nozzle inner core 1301, reduce the frequency of maintenance or replacement, and lower maintenance costs. Furthermore, the external environment may contain dust, liquids, or other impurities that may contaminate or damage the nozzle inner core 1301. The closed state of the flower bud-like structure can effectively prevent these impurities from entering the nozzle inner core 1301, maintaining its internal cleanliness and integrity, and ensuring the normal operation of the nozzle.

[0067] like Figure 11 As shown, the mounting base 306 further includes an electric telescopic rod inside. The output end of the electric telescopic rod is connected to a positioning ring 17, which is located outside the nozzle inner core 1301. The positioning ring 17 is connected to the inner wall of the protective plate 16 via a rotating rod 18. Both ends of the rotating rod 18 are hinged to the positioning ring 17 and the protective plate 16, respectively. The power supply of the electric telescopic rod is electrically connected to the power supply of the controller. When the soil moisture content is lower than a set threshold, the controller controls the electric telescopic rod to move the positioning ring 17 upwards. At this time, under the linkage of the rotating rod 18, the protective plate 16 expands outwards. After irrigation is completed, the control... The controller controls the electric telescopic rod, causing the positioning ring 17 to move downwards to reset. At this time, under the linkage of the rotating rod 18, the protective plate 16 retracts and closes. Through automatic control when the soil moisture content is lower than the set threshold, intelligent irrigation can be achieved. The sprinkler head will only automatically start and spray water when needed, thus avoiding unnecessary waste. This water-saving method is very important for environmental protection and water resource management. Through the control of the controller, the electric telescopic rod realizes the automatic opening and closing of the protective plate 16. This automated operation reduces the burden of manual operation and can carry out timely and effective irrigation management according to the soil moisture, improving work efficiency.

[0068] Working principle: When a planting area is in a water-deficient state, the soil moisture sensor 6 detects the moisture content in the planting area. When the soil moisture content is lower than the set threshold, the controller sends a signal to the air pump 9 via electrical connection, causing it to expel the gas from the air inlet pipe 8. With the air inlet pipe 8 in a gas-free state, the supporting force disappears, and the extension pipe 304 bends at the position of the corrugated pipe 305 under the action of gravity, drooping, simulating the wilting effect of plant stems in a water-deficient state. Users can observe the bending state of the corrugated pipe 305 through the external monitoring of the device, thereby directionally activating the automatic irrigation device in the planting area.

[0069] The water pump can be turned on or off remotely via a terminal, controlling the water flow into the main pipe 1 and its branch pipes 2. The controller controls the solenoid valve 7 installed on the branch pipe 2, ensuring that the branch pipe 2 in that area is connected to the main pipe 1. By monitoring soil moisture in real time and irrigating as needed, over-irrigation and waste can be avoided. Irrigation only occurs when the soil moisture is below a set threshold, effectively utilizing water resources. By installing a soil moisture sensor 6 and a controller, automated irrigation control can be achieved. No manual intervention is required; the system automatically determines whether irrigation is needed based on soil moisture, improving irrigation efficiency and accuracy. The controller controls the solenoid valve 7, allowing the corresponding branch pipe 2 to irrigate the soil in different planting areas in a targeted manner, effectively saving water resources and avoiding excessive waste. Timely irrigation can maintain suitable soil moisture, which is conducive to the normal growth and development of plants.

[0070] Water enters the interior of water injection pipe 303 through branch pipe 2, filling the interior of water injection pipe 303 and making the internal pipe of water injection pipe 303 full. With the air-assisted support of air-inflating pipe 8, the withered extension pipe 304 is rotated 180° and reset at corrugated pipe 305. At this time, extension pipe 304, corrugated pipe 305 and riser pipe 301 are on the same straight line.

[0071] The liquid medicine sprayed by the dosing tube 15 drives the impeller 1303. On the one hand, the rotation of the impeller 1303 accelerates the mixing of the liquid medicine with water. On the other hand, it causes the nozzle assembly 13 to rotate, thereby expanding the irrigation range of the equipment.

[0072] Irrigation of the planting area is achieved through irrigation component 3. The water pump can be switched on and off remotely via a remote terminal. Growers can adjust the working status of the irrigation system at any time according to actual needs without having to go to the planting area to operate it themselves.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
