Description

Technical Field

[0001] This utility model relates to the field of soil irrigation technology, specifically an adaptive irrigation device for soil. Background Technology

[0002] In agricultural production, landscaping, and ecological restoration, soil irrigation is a crucial link in maintaining normal plant growth and ensuring the stability of the ecosystem. The purpose of soil irrigation is to combat drought and conserve moisture, ensuring that the soil has a certain amount of water to meet the needs of crops for growth. The goal of soil irrigation is to meet the water needs of crops at different growth stages to achieve high yields. In order to increase the moisture in the soil, it is beneficial to the growth and development of crops, and to saturate the soil to meet the water requirements of crops.

[0003] Chinese Patent Publication No. CN215012249U discloses a soil adaptive irrigation device, including a water storage chamber. Multiple diversion pipes are uniformly fixedly connected to the bottom of the outer surface of the water storage chamber. A liquid storage tank is fixedly connected to the end of each diversion pipe away from the water storage chamber. A metering valve is provided on the side of each diversion pipe near the liquid storage tank. A guide pipe is fixedly connected to the bottom side of the end of each liquid storage tank away from the water storage chamber, extending to the top side. A drain tank is fixedly connected to the end of each guide pipe away from the liquid storage tank. In this invention, during normal operation of the water supply equipment, a portion of water can be accumulated with each irrigation. When the water supply equipment requires maintenance or malfunctions, the stored water is discharged to the soil requiring irrigation through aeration, temporarily alleviating the problem of water shortage for plants.

[0004] In existing technologies, the design intent of a soil adaptive irrigation device is to alleviate water shortage by aerating stored water when the water supply equipment fails or is under maintenance. However, it does not consider the dynamic needs of crops during normal growth (such as the need for frequent, small-volume irrigation during the seedling stage and frequent, large-volume irrigation during the maturity stage). The "accumulated water" during normal water supply is only for emergency reserves and cannot actively adjust the irrigation amount or frequency according to soil moisture and crop water requirements, thus lacking true "soil self-adaptation" capability. Therefore, we have made improvements and proposed a soil adaptive irrigation device. Utility Model Content

[0005] The purpose of this utility model is to address the problem that current soil adaptive irrigation devices lack the core function of "adaptive" and can only provide temporary emergency response, failing to adapt to the dynamic needs of crops.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: An adaptive irrigation device for soil, through the design of "connecting ring sliding connection + annular plate guiding transition", allows the nozzle to freely adjust its position and angle to adapt to the irrigation needs of different crops. By adjusting the structure, it achieves "adaptive" response to crop growth status and planting scenarios, thereby improving the above-mentioned problems.

[0007] The application is as follows: An adaptive irrigation device for soil includes a base, on both sides of which irrigation structures are symmetrically arranged.

A nozzle is provided on the side of the threaded pipe away from the connecting ring. A water delivery pipe is fixedly installed on the top of the base. As a preferred technical solution of this application, gears are rotatably connected inside the two first fixed seats and the second fixed seats. Gear rings are meshed on the outer sides of the gears and are slidably connected to the two first fixed seats and the second fixed seats. The gear rings are respectively fixedly connected to one of the annular plates on one side of the connecting rings. A first servo motor is fixedly installed inside one of the second fixed seats. A fixed rod is fixedly installed at the output end of the first servo motor. The fixed rod passes through the gears and is fixedly connected to them. The fixed rod passes through the two first fixed seats and is rotatably connected to them. The fixed rod passes through one side of the two second fixed seats and is rotatably connected to them. As a preferred technical solution of this application, a sealing ring is fixedly installed on the outer side of each of the plurality of annular plates, and a sealing ring is fixedly installed on both sides of each of the plurality of sealing rings. The plurality of sealing rings and sealing rings are slidably connected to the base, the two first fixed seats and the second fixed seat respectively. As a preferred technical solution of this application, a limiting plate is provided on the outer side of one of the annular plates of the plurality of connecting rings, and the plurality of limiting plates are slidably connected to two first fixed seats and a second fixed seat respectively. As a preferred technical solution of this application, an arc-shaped connecting block is slidably connected to the top of several connecting rings, and the two ends of several arc-shaped connecting blocks are respectively fixedly connected to the base, two first fixed seats and a second fixed seat. A bracket is provided at the bottom of the two second fixed seats. The bracket is composed of an arc-shaped plate and a triangular base, and the arc-shaped plate is inserted into the interior of the second fixed seat and slidably connected to it. As a preferred technical solution of this application, a second control valve is fixedly installed inside the connecting rings and on the through groove, and an outer tube is threadedly connected to the outside of the threaded tubes, and the outer tube is fixedly connected to the nozzle. The side of the nozzles near the outer tube is provided with a groove. As a preferred technical solution of this application, an output slot is provided on the top of the base and below the water supply pipe, a booster valve is fixedly installed inside the base and on the output slot, and a first control valve is provided on the top of the base and at the bottom of the outside of the water supply pipe. As a preferred technical solution of this application, a control module is fixedly installed inside the base. The control module is electrically connected to the booster valve, the first control valve, the second control valve and the first servo motor. Side plates are fixedly installed on the sides of the two second fixed seats that are far apart from each other. Flanges are fixedly installed on the outer sides of the two side plates and the outer side of the water pipe.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: (1) The design of connecting rings slidingly connected to the base, the first fixed seat and the first fixed seat and the second fixed seat respectively, and the guide transition structure of the ring plate, provides the core degree of freedom for adjusting the position and angle of the nozzle, so that the irrigation range can be flexibly adjusted according to the shape of the plot and the planting density of crops to meet the irrigation needs of different crops. Through the combination design of the threaded pipe and the nozzle, the modular disassembly structure is adopted, which makes it easy to directly disassemble and replace the nozzle, greatly reducing the maintenance difficulty and cost. (2) By adding an arc-shaped connecting block at the top of the connecting ring to the fixed seat and the base, the rotation of the connecting ring is guided, reducing the shaking and offset during the sliding process, ensuring that the nozzle angle adjustment is more stable, avoiding the offset of the irrigation range due to the shaking of the connecting ring, and the strong stability of the triangular base can firmly support the device on the ground, preventing the device from tipping over due to water flow impact or external force, allowing the device to adjust the overall angle according to the ground slope, adapting to uneven terrain such as mountains and hills, and expanding the application scenarios of the device.

[0017] Example 1: Please refer to the appendix of the instruction manual. Figure 1-4 An adaptive irrigation device for soil includes a base 1. Irrigation structures are symmetrically arranged on both sides of the base 1. Each irrigation structure includes a first fixed seat 2 and a second fixed seat 3. A connecting ring 4 is provided on the side of the first fixed seat 2 and the second fixed seat 3 closest to the base 1. One connecting ring 4 is slidably connected to the base 1 and the first fixed seat 2, and the other connecting ring 4 is slidably connected to the first fixed seat 2 and the second fixed seat 3. Annular plates 7 are fixedly installed on corresponding sides of the two connecting rings 4. The inner and outer diameters of the annular plates 7 are smaller than the inner and outer diameters of the connecting rings 4. The annular plates 7 on both sides of one connecting ring 4 are inserted into the base 1 and the first fixed seat 2 and slidably connected thereto. The annular plates 7 on both sides of the other connecting ring 4 are inserted into the first fixed seat 2 and the second fixed seat 3 and slidably connected thereto. A threaded pipe 5 is fixedly installed on one side of each of the connecting rings 4, and a through groove is provided on the connecting ring 4 to mate with the threaded pipe 5. A nozzle 20 is provided on the side of the threaded pipe 5 away from the connecting ring 4. A water supply pipe 15 is fixedly installed on the top of the base 1.

[0018] In this embodiment of the utility model, the water supply pipe 15 serves as the main water supply channel, delivering external water to the interior of the base 1. The water inside the base 1 flows into the connecting ring 4 through the communication structure with the connecting ring 4, and then flows into the threaded pipe 5 through the through groove on the connecting ring 4 that cooperates with the threaded pipe 5. Finally, it is sprayed out by the nozzle 20 to irrigate the soil. Since the connecting ring 4 is slidably connected to the base 1, the first fixed seat 2, and the first fixed seat 2 and the second fixed seat 3 respectively, and the annular plate 7 plays a guiding and connecting transition role, the connecting ring 4 can rotate or move within a certain range, thereby driving the threaded pipe 5 and the nozzle 20 to adjust their position and angle, and change the irrigation coverage area.

[0019] In this embodiment of the utility model, the symmetrically arranged irrigation structure can simultaneously irrigate the soil on both sides of the base 1, improving irrigation efficiency and avoiding the situation where local soil irrigation is inadequate; the sliding connection between the connecting ring 4 and each fixed seat, combined with the design of the annular plate 7, provides a flexible structural basis for adjusting the position and angle of the nozzle 20, allowing for flexible changes in the irrigation range according to changes in soil irrigation needs, adapting to irrigation scenarios of different plot sizes and shapes; the combination structure of the threaded pipe 5 and the nozzle 20 facilitates the installation, disassembly, and replacement of the nozzle 20, and allows for quick repair or replacement when the nozzle 20 becomes clogged or damaged, reducing device maintenance costs and ensuring the continuity of irrigation work.

[0020] Example 2: Please refer to the appendix of the instruction manual. Figure 1-6 In a preferred embodiment of this utility model, gears 9 are rotatably connected inside the two first fixed seats 2 and the second fixed seat 3. Gear rings 8 are meshed on the outer sides of several gears 9, and the gear rings 8 are slidably connected to the two first fixed seats 2 and the second fixed seat 3. Several gear rings 8 are respectively fixedly connected to one of the annular plates 7 on one side of several connecting rings 4. A first servo motor 12 is fixedly installed inside one of the second fixed seats 3. A fixing rod 13 is fixedly installed at the output end of the first servo motor 12. The fixing rod 13 passes through several gears 9 and is fixedly connected to them. The fixing rod 13 passes through the two first fixed seats 2 and is rotatably connected to them. The fixing rod 13 passes through one side of the two second fixed seats 3 and is rotatably connected to them.

[0021] A sealing ring 10 is fixedly installed on the outer side of several annular plates 7, and a sealing ring is fixedly installed on both sides of several sealing rings 10. The sealing rings 10 and the sealing rings are slidably connected to the base 1, the two first fixed seats 2 and the second fixed seat 3 respectively.

[0022] A limiting plate 11 is provided on the outer side of one of the annular plates 7 of the several connecting rings 4. The limiting plates 11 are slidably connected to two first fixed seats 2 and a second fixed seat 3 respectively. The limiting plate 11 slides 270 degrees inside the first fixed seat 2 or the second fixed seat 3.

[0023] Several connecting rings 4 are slidably connected to the top of an arc-shaped connecting block 16. The two ends of the arc-shaped connecting block 16 are respectively fixedly connected to the base 1, two first fixed seats 2 and second fixed seats 3. The bottom of the two second fixed seats 3 is provided with a bracket 18. The bracket 18 is composed of an arc-shaped plate and a triangular base, and the arc-shaped plate is inserted into the interior of the second fixed seat 3 and slidably connected to it.

[0024] A second control valve is fixedly installed inside several connecting rings 4 and located on the through groove. An outer tube 6 is threadedly connected to the outside of several threaded tubes 5, and the outer tube 6 is fixedly connected to the nozzle 20. A groove 19 is provided on the side of several nozzles 20 near the outer tube 6.

[0025] An output slot is provided on the top of the base 1 and below the water supply pipe 15. A booster valve is fixedly installed inside the base 1 and on the output slot. A first control valve is provided on the top of the base 1 and at the bottom outside the water supply pipe 15.

[0026] A control module 14 is fixedly installed inside the base 1. The control module 14 is electrically connected to the booster valve, the first control valve, the second control valve and the first servo motor 12. Side plates 17 are fixedly installed on the sides of the two second fixed seats 3 that are far apart from each other. Flanges are fixedly installed on the outer sides of the two side plates 17 and the outer side of the water pipe 15.

[0027] In this embodiment of the invention, when it is necessary to adjust the irrigation angle of the nozzle 20, the first servo motor 12 is started. The output end of the first servo motor 12 drives the fixed rod 13 to rotate. Since the fixed rod 13 is fixedly connected to several gears 9, the rotation of the fixed rod 13 will synchronously drive all gears 9 to rotate inside the first fixed seat 2 and the second fixed seat 3. When the gears 9 rotate, the gear ring 8 that meshes with them will slide inside the first fixed seat 2 and the second fixed seat 3. Since the gear ring 8 is fixedly connected to the annular plate 7 of the connecting ring 4, the sliding of the gear ring 8 will drive the connecting ring 4 to rotate around its own axis or a specified trajectory. The connecting ring 4 will then drive the threaded tube 5 and the nozzle 20 to rotate, thereby achieving precise adjustment of the irrigation angle.

[0028] When the device is irrigating, the water flows in the channel between the base 1, the connecting ring 4, the first fixed seat 2, and the second fixed seat 3. Since the annular plate 7 is inserted into the base 1, the first fixed seat 2, and the second fixed seat 3 and slidably connected, the sealing ring 10 on the outside of the annular plate 7 and the sealing rings on both sides of the sealing ring 10 will be tightly attached to the inner wall of the base 1, the first fixed seat 2, and the second fixed seat 3. During the process of the connecting ring 4 driving the annular plate 7 to slide, the sealing ring 10 and the sealing rings always maintain close contact with the inner wall, blocking the channel for water to leak from the gap between the annular plate 7 and the inner wall of each component.

[0029] When the first servo motor 12 drives the connecting ring 4 to slide and adjust its angle inside the first fixed seat 2 or the second fixed seat 3 via the annular plate 7, the limiting plate 11 on the outer side of the annular plate 7 will slide together with the annular plate 7 inside the first fixed seat 2 or the second fixed seat 3. When the limiting plate 11 slides to the preset limiting position inside the first fixed seat 2 or the second fixed seat 3, the limiting plate 11 will contact the limiting structure and be blocked, thereby limiting the annular plate 7 from continuing to slide, and thus limiting the rotation angle of the connecting ring 4, so that the rotation angle of the connecting ring 4 driving the nozzle 20 is controlled within the range of 270 degrees.

[0030] In this embodiment of the invention, when the connecting ring 4 rotates around its own axis or a designated trajectory to adjust its angle, the top of the connecting ring 4 slides relative to the arc-shaped connecting block 16. Since the arc-shaped connecting block 16 is fixed at both ends to the base 1, the first fixed seat 2, and the second fixed seat 3, its arc-shaped structure matches the rotation trajectory of the connecting ring 4, guiding the rotation of the connecting ring 4 and ensuring that the connecting ring 4 rotates stably along the preset trajectory. For the bracket 18, the triangular base has good stability, providing stable support for the entire device on the ground. When it is necessary to adjust the installation angle of the device or adapt to the ground slope, the second fixed seat 3 can be pushed, causing it to slide relative to the arc-shaped plate of the bracket 18 until a suitable angle is achieved. Then, the relative position of the bracket 18 and the second fixed seat 3 is maintained, thus adjusting the overall angle of the device.

[0031] During irrigation, the second control valve can open and close the channel and adjust the degree of opening according to the control command. When it is necessary to irrigate a certain area, the second control valve on the corresponding connecting ring 4 is opened, and the water flow can enter the threaded pipe 5 through the channel. By adjusting the degree of opening of the second control valve, the flow rate of the water entering the threaded pipe 5 can be controlled, thereby controlling the water output of the nozzle 20. The threaded connection between the threaded pipe 5 and the outer pipe 6 allows the relative position of the nozzle 20 and the threaded pipe 5 to be adjusted by rotating the outer pipe 6, thereby fine-tuning the height and irrigation angle of the nozzle 20. The groove 19 on the side of the nozzle 20 near the outer pipe 6 can play a buffering and guiding role when the water flows into the nozzle 20, so that the water flow is sprayed out from the nozzle 20 more evenly.

[0032] After the external water source enters the base 1 through the water supply pipe 15, it first passes through the first control valve. The first control valve can connect or block the water supply pipe 15 with the internal channel of the base 1 according to the control command. When irrigation is needed, the first control valve is opened and the water flows into the base 1. When irrigation ends or irrigation needs to be suspended, the first control valve is closed to cut off the water flow. The water flowing into the base 1 flows through the output channel to each connecting ring 4. When the water flows through the output channel, the pressure boosting valve inside the base 1 can pressurize the water flow according to the actual irrigation needs, increase the water pressure, and enable the water flow to pass more smoothly through the connecting ring 4, the threaded pipe 5 and spray out from the nozzle 20, ensuring the irrigation distance and coverage.

[0033] The control module 14, as the core of the device's control, can receive external control commands or signals from internal sensors to coordinate the control of the booster valve, the first control valve, the second control valve, and the first servo motor 12. For example, when the control module 14 receives a command to increase the irrigation water volume, it controls the booster valve to increase the pressure, and can adjust the opening degree of the first and second control valves as needed. When the irrigation angle needs to be adjusted, the control module 14 sends a control signal to the first servo motor 12 to control its start, stop, rotation angle, and speed. The flanges on the outer side of the side plate 17 and the outer side of the water supply pipe 15 are mainly used for connecting the device to external equipment or pipelines. For example, the flange of the water supply pipe 15 can securely connect the device to an external water supply pipeline, and the flange of the side plate 17 can connect the device to other auxiliary fixed equipment, enhancing the stability of the device installation. At the same time, the device is provided with heat dissipation holes to cooperate with the servo motor.

[0034] Example 3: Please refer to the appendix of the instruction manual. Figure 1-2 In a preferred embodiment of this utility model, an auxiliary seat is fixedly installed at the bottom of the base 1, a second servo motor is embedded at the bottom of the auxiliary seat, a fixed cylinder is rotatably connected to the bottom of the auxiliary seat, the output end of the second servo motor is fixedly connected to the fixed cylinder, a threaded rod is provided at the bottom of the fixed cylinder, and the threaded rod is inserted into the inside of the fixed cylinder and threadedly connected to it, a square plate is fixedly installed at the top of the threaded rod, and the square plate is slidably connected to the fixed cylinder, an adjusting block is fixedly installed at the bottom of the threaded rod, and several sensors are provided inside the adjusting block, including a soil moisture sensor, a soil temperature sensor, a soil conductivity sensor, and a plant stem diameter sensor, a probe is fixedly installed at the bottom of the adjusting block, and a through hole is opened on the adjusting block (to facilitate the insertion of an external rod into the ground, so that the second servo motor drives the adjusting block to slide along the external rod), the control module 14 is electrically connected to the second servo motor and several sensors, and the control module 14 is electrically connected to the peripheral controller.

[0035] In this embodiment of the invention, when the device is running, the probe at the bottom of the adjusting block is inserted into the soil, and various sensors inside the adjusting block collect soil and crop-related data in real time through the probe. Among them, the soil moisture sensor detects soil moisture content, the soil temperature sensor obtains soil temperature, the soil conductivity sensor monitors soil fertility, and the plant stem diameter sensor senses the crop growth status by contacting the crop stem. This collected data is transmitted in real time to the control module 14, which is electrically connected to it. When it is necessary to adjust the sensor detection position according to different soil depths, or when positioning the adjustment block during the initial installation of the device, a command can be sent to the control module 14 via the external controller. After receiving the command, the control module 14 starts the second servo motor at the bottom of the auxiliary base. The output of the second servo motor drives the fixed cylinder, which is fixedly connected to it, to rotate. Since the threaded rod is threadedly connected to the fixed cylinder, and the square plate at the top of the threaded rod is slidably connected to the fixed cylinder (restricting the threaded rod from rotating synchronously with the fixed cylinder), the rotation of the fixed cylinder drives the threaded rod to move up and down along the axis of the fixed cylinder, thereby driving the adjustment block at the bottom of the threaded rod to move up and down synchronously. At the same time, the through hole on the adjustment block is fitted onto the external rod body, and the external rod body is inserted into the ground to act as a guide, ensuring that the adjustment block slides along a fixed trajectory during the up and down movement, avoiding deviation, and accurately adjusting to the target detection depth or position. After receiving the data transmitted by the sensor, the control module 14 analyzes and processes the data. If the analysis finds that the soil moisture is lower than the suitable growth threshold for crops, or if the analysis combined with data on soil temperature, electrical conductivity, and plant stem diameter indicates that the crop's water requirement has increased, the control module 14 will automatically send control signals to the first control valve, the second control valve, the pressure boosting valve, and the first servo motor 12 to adjust parameters such as irrigation water volume and irrigation angle to achieve adaptive irrigation. At the same time, the control module 14 can also transmit the collected data and analysis results to an external controller for real-time monitoring by staff. Staff can manually intervene in the irrigation operation through the external controller.

[0036] In this embodiment of the invention, a combination of multiple types of sensors comprehensively covers key indicators such as soil moisture, temperature, fertility, and crop growth status, avoiding the limitations of single data collection. Real-time and accurate data transmission is sent to the control module 14, enabling the device to adjust irrigation strategies based on actual soil and crop conditions. Simultaneously, through the cooperation of the second servo motor, fixed cylinder, threaded rod, and external rod, the vertical position of the adjusting block can be flexibly adjusted to detect soil conditions at different depths. This is suitable for different crops (such as shallow-rooted and deep-rooted crops) with varying soil detection depth requirements, and can also handle areas with distinct soil stratification, improving the comprehensiveness and specificity of the detection. Several sensors and a second servo motor are electrically connected to the control module 14, and the control module 14 is linked with the peripheral controller, realizing an automated closed loop of data acquisition, position adjustment, and irrigation control. Workers do not need frequent on-site operation; they can remotely monitor and control the system through the peripheral controller, reducing labor intensity. Simultaneously, dynamic irrigation adjustments based on real-time data reduce water waste and improve irrigation efficiency and crop yield. The sliding fit between the square plate and the fixed cylinder, as well as the guiding design of the external rod and the through-hole of the adjusting block, effectively prevent the adjusting block from rotating or shifting during movement, ensuring the accuracy of the sensor's detection position. The fixed connection between the probe and the adjusting block ensures the stability of sensor data acquisition and reduces the impact of external interference on data accuracy.

Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
