Description

[0002] Traditional garden irrigation methods mostly use surface flooding or sprinkler spraying. Such methods have low water resource utilization rate, large evaporation loss and uneven irrigation, which not only causes a large amount of water resource waste, but also may cause plant root rot due to long-term water accumulation on the ground, affecting plant growth.

[0003] In view of the above problems, traditional common garden irrigation methods include sprinkling irrigation and drip irrigation. The sprinkling irrigation system sprays water mist on the surface of plants through a water spraying pipe. The drip irrigation system can directly deliver water to the plant roots, but usually needs to lay a complex pipe system, and the drip head is easy to be blocked. These existing irrigation methods are difficult to accurately deliver water to the periphery of the plant roots, which may cause water evaporation waste or insufficient water absorption by plants, affecting the irrigation effect.

[0025] In addition, in the description of the present application, the terms "first", "second", and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0026] As Figure 1 shown, it shows a garden water-saving irrigation device in an embodiment of the present application, which comprises a water delivery pipe 1, an annular water injection pipe 2 and an insertion pipe 3. Among them, the water delivery pipe 1 is a metal straight pipe, the annular water injection pipe 2 is arranged at the end of the water delivery pipe 1 and communicates with the water delivery pipe 1, and the opening 201 is formed on the outer side wall of the annular water injection pipe 2. The opening 201 faces away from the water delivery pipe 1, and it should be noted that the annular water injection pipe 2 is C-shaped, and through this opening 201, the annular water injection pipe 2 can smoothly enter the peripheral area of the garden plant, and it can be understood that the width of the opening 201 is greater than the diameter of the plant, and the annular water injection pipe 2 of the present application can irrigate trees, flowers and plants, and shrubs, etc. In order to be suitable for plants of different specifications, annular water injection pipes 2 of different diameter specifications can be selected.

[0027] Secondly, in order to directly irrigate the plant roots and reduce water evaporation, the insertion pipe 3 is arranged, and during irrigation, the insertion pipe 3 is directly inserted into the soil, so that water can be delivered to the plant roots. Specifically, the number of insertion pipes 3 is several, and these insertion pipes 3 are arranged on the bottom surface of the annular water injection pipe 2 at certain intervals, and each insertion pipe 3 communicates with the annular water injection pipe 2. In addition, a plurality of water injection holes 301 are distributed on the inner circumferential wall of the annular water injection pipe 2 and the outer circumferential wall of the insertion pipe 3, which are specially used for irrigation operation to the peripheral part of the garden plant roots. It should be emphasized that the annular water injection pipe 2 does not enter the ground, and when the insertion pipe 3 is completely inserted into the soil, the annular water injection pipe 2 is tightly attached to the ground.

[0028] In some examples, taking the operation personnel hand-holding the water supply pipe 1 as an example, the water supply pipe 1 is communicated with an external water source, and when irrigation is performed, first, the annular water injection pipe 2 is placed around the periphery of the garden plant through the opening 201 on the outer wall of the annular water injection pipe 2, to ensure that the annular water injection pipe 2 can surround the plant. Then, a plurality of insertion pipes 3 arranged at intervals on the bottom surface of the annular water injection pipe 2 are synchronously inserted into the soil around the garden plant, so that the insertion pipes 3 extend into the soil near the plant roots. Subsequently, the water source is connected to the water supply pipe 1, and the water flow enters the annular water injection pipe 2 communicated with the water supply pipe 1. The water flow entering the annular water injection pipe 2, part of it will be directly sprayed to the soil surface around the plant roots through the water spraying holes 301 on the inner wall of the annular water injection pipe 2, and the other part of the water flow will flow into the insertion pipes 3 communicated with the annular water injection pipe 2, and then penetrate into the soil through the water spraying holes 301 on the outer wall of the insertion pipes 3, directly and quickly acting on the area around the plant roots, thereby completing the irrigation process of the garden plant.

[0029] In summary, the irrigation device of the present application effectively solves the problems of low water resource utilization rate, large evaporation loss and uneven irrigation of the traditional garden irrigation method. Through the water spraying holes 301 on the annular water injection pipe 2 and the insertion pipes 3, water can be accurately and quickly delivered to the periphery of the plant roots, reducing the evaporation loss of water during the infiltration process and improving the utilization rate of water resources. At the same time, the insertion pipes 3 spray water into the soil, avoiding the long-term surface waterlogging phenomenon caused by surface flooding, preventing the plant roots from rotting due to waterlogging, and ensuring the normal growth of the plants. Moreover, the annular water injection pipe 2 is arranged around the plant, and the insertion pipes 3 are arranged at intervals, so that water can be uniformly distributed around the plant roots, achieving uniform irrigation, improving the irrigation effect, and avoiding the situation that the insufficient water absorption in some areas affects the growth of plants due to uneven irrigation.

[0030] As shown in Figure 1 The end of the insertion pipe 3 away from the annular water injection pipe 2 is provided with a pointed end cap 4 through a rotating connection, the outer wall of the pointed end cap 4 is fixedly provided with a threaded blade 41, the threaded blade 41 can rotate together with the pointed end cap 4, and the insertion pipe 3 can be inserted into the soil around the garden plant through the rotation of the threaded blade 41.

[0031] Specifically, the motor can be directly installed in the insertion pipe 3 by driving the pointed cone end cap 4 to rotate. In actual use, when the insertion pipe 3 needs to be inserted into the soil around the garden plants, the staff starts the motor while applying a certain downward pressure to drive the motor to drive the pointed cone end cap 4 to rotate, and the pointed cone end cap 4 drives the threaded blades 41 on the outer peripheral wall to rotate. Due to the rotating action of the pointed end of the pointed cone end cap 4 and the threaded blades 41, the resistance of the insertion pipe 3 during insertion into the soil is greatly reduced, and the staff only needs to apply a small downward pressure to make the insertion pipe 3 smoothly and gradually penetrate into the soil until the appropriate insertion depth is reached, meeting the demand for water delivery to the periphery of the plant roots during irrigation. During irrigation, the water flows through the water delivery pipe 1 into the annular water injection pipe 2, is then distributed to the insertion pipe 3, and finally is sprayed out of the water spray hole 301, achieving irrigation of the periphery of the plant roots. During this process, the pointed cone end cap 4 and the threaded blades 41 remain stationary and do not affect the irrigation operation.

[0032] Therefore, compared with the difficulty of inserting the pipe into the soil in the traditional drip irrigation system, the combination of the pointed cone end cap 4 and the threaded blades 41 greatly reduces the difficulty of inserting the insertion pipe 3 into the soil, saves the staff's physical strength and time, and improves the installation efficiency of the irrigation device. At the same time, the presence of the threaded blades 41 can make the insertion pipe 3 more stably fixed in the soil, avoiding displacement of the insertion pipe 3 due to water flow impact or other external factors during irrigation, ensuring the stability and accuracy of irrigation, further improving the irrigation effect, reducing the problem of water not being accurately delivered to the periphery of the roots due to displacement of the insertion pipe 3, and thus better saving water resources and protecting plant growth.

[0033] Further, as shown in Figure 2 and Figure 3 , a turbine 5 is rotatably arranged inside the insertion pipe 3, the turbine 5 is driven to rotate by water flow and is in transmission connection with the pointed cone end cap 4. The turbine 5 is composed of a rotating shaft 51 and a turbine 52, the rotating shaft 51 is rotatably arranged inside the insertion pipe 3, the arrangement direction of the rotating shaft 51 is consistent with the axial direction of the insertion pipe 3, and one end of the rotating shaft 51 is fixedly connected with the pointed cone end cap 4. The turbine 52 is installed on the rotating shaft 51, a circular ring 53 is arranged on the outer periphery of the turbine 52, and the turbine 52 is in sliding abutment with the inner wall of the insertion pipe 3 through the circular ring 53. The turbine 52 has a plurality of turbine blades 521 arranged at intervals according to the circumference, and water flow channels 520 are formed between adjacent turbine blades 521. It should be noted that compared with directly installing a driving motor in the insertion pipe 3, using water flow to drive the turbine can better increase the use effect and universality of the device.

[0034] Specifically, when irrigation is performed, water flows into the annular water injection pipe 2 from the water supply pipe 1, and then flows into the insertion pipe 3. The water in the insertion pipe 3 flows in a direction from top to bottom. It should be noted that the water in the insertion pipe 3 is high-pressure water. When the water passes the position of the turbine 52, it enters the water flow channel 520 formed between adjacent turbine blades 521. The water flowing in the water flow channel 520 impacts the turbine blades 521, causing the turbine blades 521 to move, thereby driving the turbine 52 to rotate as a whole. Since the turbine 52 is fixed to the rotating shaft 51, the turbine 52 drives the rotating shaft 51 to rotate when the turbine 52 rotates. The one end of the rotating shaft 51 is fixedly connected to the pointed end cap 4, so that the rotating shaft 51 drives the pointed end cap 4 to rotate when the rotating shaft 51 rotates. The pointed end cap 4 drives the threaded blades 41 on the outer circumferential wall of the pointed end cap 4 to rotate. Under the action of the threaded blades 41, the insertion pipe 3 is automatically inserted into the soil around the garden plants. When the insertion pipe 3 reaches the appropriate depth, the operator stops applying downward pressure or reduces the downward pressure, so that the water continues to be sprayed out through the water injection hole 301 to irrigate the periphery of the plant roots. At this time, the turbine 5 slowly rotates under the action of the water flow, but the insertion pipe 3 will not continue to penetrate into the soil. By controlling the flow rate of the water in the insertion pipe 3, the rotation speed of the pointed end cap 4 can be controlled.

[0035] Secondly, it can be understood that, by using the water flow to drive the turbine 52 to rotate, when the insertion pipe 3 is not inserted into the soil, the water in the insertion pipe 3 will also be sprayed out from the water injection hole 301. However, it should be noted that the water at this time has two effects, one is the effect of irrigation, and the other is the effect of wetting the ground. In this way, the insertion pipe 3 can be more quickly inserted into the soil. At this time, water resources will not be wasted, and in actual use, the insertion action of the insertion pipe 3 is very fast, so too much water will not be sprayed out during the insertion process.

[0036] Therefore, by using the water flow to drive the turbine 5 to rotate, and then drive the pointed end cap 4 and the threaded blades 41 to rotate, the automatic insertion of the insertion pipe 3 is realized, without the need for the staff to manually rotate the pointed end cap 4, further saving the labor cost and improving the efficiency of the insertion pipe 3 inserted into the soil. It is especially suitable for large-area garden irrigation operations, which greatly improves the overall irrigation efficiency. At the same time, the annular ring 53 on the outer periphery of the turbine 52 is in sliding abutment with the inner wall of the insertion pipe 3, which can ensure the stability of the turbine 52 during rotation, avoid the turbine 52 from being deviated due to water impact, and ensure the reliability of the transmission, so that the insertion pipe 3 can be stably and smoothly inserted into the soil. In addition, by using water flow to drive, there is no need to additionally set a power device, which is more energy-saving and environmentally friendly, in line with the concept of water-saving irrigation, reduces energy consumption, and also avoids possible failure problems of the additional power device, improves the overall reliability and service life of the irrigation device.

[0037] For example, as shown in FIG. 6, the annular ring 53 on the outer periphery of the turbine 52 is in sliding abutment with the inner wall of the insertion pipe 3, which can ensure the stability of the turbine 52 during rotation, avoid the turbine 52 from being deviated due to water impact, and ensure the reliability of the transmission, so that the insertion pipe 3 can be stably and smoothly inserted into the soil. Figure 3 and Figure 4As shown, the shaft 51 is provided with a flow splitting cone block 54, which is located directly above the turbine 52 and the turbine blades 521 are located at the outer periphery of the flow splitting cone block 54. The flow splitting cone block 54 has a conical structure, with the small-diameter end of the flow splitting cone block 54 facing upwards above the insertion pipe 3. The flow splitting cone block 54 can guide the water flow from top to bottom in the insertion pipe 3 to split, so that the water flow can accurately flow to the turbine blades 521.

[0038] In some examples, when irrigating, the water flow flows from above the insertion pipe 3. When the water flow reaches the position of the flow splitting cone block 54, due to the conical structure of the flow splitting cone block 54 with the small-diameter end facing upwards, the water flow will be guided to split along the conical surface of the flow splitting cone block 54 and spread to the outer periphery of the flow splitting cone block 54. Since the turbine blades 521 are located at the outer periphery of the flow splitting cone block 54, the water flow after splitting can accurately flow to each turbine blade 521 and enter the water flow channel 520 between adjacent turbine blades 521. The water flow impacts the turbine blades 521, driving the turbine 52, the shaft 51, the pointed end cap 4 and the threaded blade 41 to rotate, so that the insertion pipe 3 is automatically inserted into the soil. After being inserted in place, the water flow continues to be sprayed out through the water spraying holes 301 for irrigation. The flow splitting cone block 54 continues to guide the water flow, ensuring that part of the water flow continues to act on the turbine blades 521, maintaining the slow rotation of the turbine 52, while not affecting the normal water supply of the water spraying holes 301.

[0039] It can be understood that the arrangement of the flow splitting cone block 54 solves the problem that the water flow in the insertion pipe 3 may be concentrated and cannot uniformly and fully act on the turbine blades 521. Through the guidance and splitting of the flow splitting cone block 54, the water flow can be more uniformly and comprehensively directed to the turbine blades 521, ensuring that each turbine blade 521 can be effectively impacted by the water flow, so that the turbine 52 can stably and efficiently rotate, ensuring that the rotation power of the pointed end cap 4 and the threaded blade 41 is sufficient, further improving the stability and efficiency of the automatic insertion of the insertion pipe 3 into the soil. At the same time, uniform water flow impact can also reduce the wear of the turbine blades 521 due to uneven force, prolong the service life of the turbine 5, reduce the maintenance cost of the irrigation device, ensure long-term stable operation of the irrigation device, better achieve water-saving irrigation, and promote plant growth.

[0040] For example, as shown in Figure 6 The garden water-saving irrigation device is further provided with a mobile frame 6 and a water tank 7. The water tank 7 is installed on the mobile frame 6, the water supply pipe 1 is in communication with the water tank 7, and the annular water injection pipe 2 is arranged on the outer side of the mobile frame 6, facilitating irrigation of the garden plants around the mobile frame 6.

[0041] In some examples, before irrigating the garden, the worker first fills the water tank 7 with water, then pushes the mobile frame 6 to move the device to the area of ​​garden plants that need irrigation. Since the annular water inlet pipe 2 is located outside the mobile frame 6, it is positioned near the outer periphery of the plant after the frame reaches the target location. Next, the annular water inlet pipe 2 is adjusted to a suitable position through the opening 201 on its outer wall, so that it surrounds the plant, and then the insertion pipe 3 is inserted into the soil around the plant. Afterwards, the control switch is turned on, and water from the water tank 7 flows into the annular water inlet pipe 2 through the water delivery pipe 1 under the action of the water pump 11. The water then irrigates the outer periphery of the plant roots through the spray holes 301 on the inner wall of the annular water inlet pipe 2 and the outer wall of the insertion pipe 3, respectively. Once one area is irrigated, the worker pushes the mobile frame 6 to move the device to the next area that needs irrigation, repeating the above operation to irrigate garden plants in different areas.

[0042] The mobile frame 6 enables the irrigation system to be mobile. Compared to the limitations of traditional fixed irrigation systems that can only irrigate specific areas, this system can be flexibly moved between different areas of the garden, facilitating irrigation of plants in different locations and improving the applicability and flexibility of the irrigation system. The water tank 7 solves the problem of traditional irrigation methods relying on a fixed water source. Workers can fill the water tank 7 and carry the system to areas of the garden far from a fixed water source, expanding the coverage of irrigation operations. At the same time, the combination of the mobile frame 6 and the water tank 7 makes irrigation operations more convenient and efficient, reducing the trouble and time costs associated with laying temporary water pipes, further improving the efficiency of garden irrigation, better meeting the actual needs of garden irrigation, ensuring even water absorption by plants, and reducing water waste.

[0043] For example, such as Figure 5 and Figure 6 As shown, the water supply pipe 1 is a telescopic pipe, specifically composed of a fixed pipe section 101 and a telescopic pipe section 102. The fixed pipe section 101 is installed on the mobile frame 6 and is connected to the water tank 7. There are two telescopic pipe sections 102, which are slidably installed at both ends of the fixed pipe section 101, and the two telescopic pipe sections 102 are located on the outside of both sides of the mobile frame 6. Each telescopic pipe section 102 has an annular water injection pipe 2 installed at the end away from the mobile frame 6, so as to irrigate the plants on both sides of the mobile frame 6 simultaneously.

[0044] Specifically, before the irrigation operation starts, the telescopic length of the telescopic pipe section 102 is adjusted according to the distance between the garden plants that need to be irrigated. The staff manually pulls or pushes the telescopic pipe section 102 to make the telescopic pipe section 102 slide along the fixed pipe section 101, so as to change the distance between the two annular water injection pipes 2 at the ends of the telescopic pipe section 102, and ensure that the two annular water injection pipes 2 can correspond to the outer periphery of the plants on both sides of the moving frame 6 respectively. After adjustment, the two annular water injection pipes 2 are wrapped around the plants through the openings 201 thereof, and the insertion pipes 3 are inserted into the soil. Then, the water in the water tank 7 flows into the two telescopic pipe sections 102 through the fixed pipe section 101, and then enters the annular water injection pipes 2, and finally irrigates the outer periphery of the roots of the plants on both sides through the water injection holes 301. When it is necessary to move the device to the next area, the telescopic pipe section 102 can be retracted to reduce the overall volume of the device, so as to facilitate the movement of the moving frame 6, and after reaching the new area, the length of the telescopic pipe section 102 is adjusted according to the distance between the plants for subsequent irrigation.

[0045] The telescopic water delivery pipe 1 can be flexibly adjusted according to the distance between the garden plants, solving the problem that the traditional fixed-length water delivery pipe 1 cannot adapt to the irrigation of plants with different distances. The two telescopic pipe sections 102 correspond to the plants on both sides of the moving frame 6 respectively, achieving simultaneous irrigation of the plants on both sides, greatly improving the irrigation efficiency and reducing the irrigation operation time. When moving the device, retracting the telescopic pipe section 102 can reduce the occupied space of the device, so that the moving frame 6 can also move smoothly in the narrow passages of the garden, improving the traffic capacity and flexibility of the device in complex garden environments. In addition, the telescopic pipe has a simple structure and is easy to operate, without the need for complex adjustment mechanisms, reducing the manufacturing cost and maintenance difficulty of the device, further improving the practicality and economy of the device, and better meeting the diversified irrigation needs of the garden and saving water resources.

[0046] For example, as Figure 5 and Figure 6As shown, the mobile frame 6 is provided with a driving assembly 8 for driving the telescopic pipe sections 102 to slide. The driving assembly 8 comprises a mounting seat 81, gears 82, first swing rods 83 and second swing rods 84. The mounting seat 81 is fixed on the mobile frame 6, and two gears 82 are rotatably arranged in the mounting seat 81 and mesh with each other. One of the gears 82 is a driving gear 82 which can be driven to rotate by an external power source (such as a motor). Both gears 82 are provided with shafts, and the shafts of the gears 82 extend out of the mounting seat 81 through the side walls of the mounting seat 81. The first swing rods 83 are provided with two ends, and one end of each of the first swing rods 83 is fixedly connected with the shaft of the gear 82. When the shaft rotates, the first swing rods 83 can be driven to swing. The second swing rods 84 are also provided with two ends, and one end of each of the second swing rods 84 is hingedly connected with the end of the first swing rod 83 away from the shaft. The other end of each of the second swing rods 84 is hingedly connected with the outer wall of the telescopic pipe section 102. The second swing rods 84 can swing following the swing of the first swing rods 83, and in turn drive the telescopic pipe sections 102 to slide along the fixed pipe section 101.

[0047] In some examples, when the length of the telescopic pipe sections 102 needs to be adjusted to adapt to the plant spacing, the external power source of the driving assembly 8 is started to drive the driving gear 82 to rotate. Since the two gears 82 mesh with each other, the rotation of the driving gear 82 can drive the other gear 82 to rotate together, and the rotation directions of the two gears 82 are opposite. When the gears 82 rotate, the shafts of the gears 82 drive the first swing rods 83 fixedly connected therewith to swing, and the two first swing rods 83 swing in opposite directions. During the swing of the first swing rods 83, the second swing rods 84 are driven to swing through the hinged connection points, and the two second swing rods 84 also move in opposite directions. Since the other end of the second swing rod 84 is hingedly connected with the outer wall of the telescopic pipe section 102, the swing of the second swing rod 84 can be converted into the sliding of the telescopic pipe section 102 along the fixed pipe section 101. One telescopic pipe section 102 extends outward, and the other telescopic pipe section 102 also extends outward, so as to change the distance between the two annular water injection pipes 2 until the length matches the plant spacing. After the adjustment is completed, the driving assembly 8 is stopped to work, and irrigation is performed. After the irrigation is completed, the driving assembly 8 can be used to drive the gears 82 to rotate in the reverse direction, so that the telescopic pipe sections 102 are retracted, and the device is moved conveniently.

[0048] The arrangement of the driving assembly 8 realizes the automatic telescopic adjustment of the telescopic pipe section 102, especially in the case of large-area gardens with large plant spacing, which can save a lot of manpower and improve the adjustment efficiency and accuracy of the telescopic pipe section 102. The two intermeshing gears 82 drive the first swing rod 83 and the second swing rod 84 to move, synchronizing and symmetrizing the telescopic actions of the two telescopic pipe sections 102, ensuring that the two annular water injection pipes 2 can accurately correspond to the plants on both sides, avoiding the problem of position deviation of the annular water injection pipe 2 caused by the inconsistent telescopic lengths of the two sides during manual adjustment, and improving the accuracy of irrigation. In addition, the driving assembly 8 has stable structure and reliable transmission, which can stably drive the telescopic pipe section 102 to move for a long time, reducing the failure rate of the device, reducing the maintenance cost, further improving the automation level and practicality of the entire irrigation device, better meeting the needs of large-scale garden irrigation, improving the irrigation effect, and saving water resources.

[0049] For example, as shown in Figure 1 and Figure 6 The telescopic pipe section 102 is provided with a water outlet 103, and the annular water injection pipe 2 is provided with a water inlet 202, and the water inlet 202 and the water outlet 103 are communicated through a hose, ensuring that the water flow can smoothly flow from the telescopic pipe section 102 into the annular water injection pipe 2.

[0050] In some examples, when adjusting the telescopic length of the telescopic pipe section 102 through the driving assembly 8, the telescopic pipe section 102 will slide along the fixed pipe section 101. Since the annular water injection pipe 2 is connected to the water outlet 103 of the telescopic pipe section 102 through the hose, the hose has good flexibility and telescopic property, and can freely telescope or bend with the movement of the telescopic pipe section 102, without affecting the normal sliding of the telescopic pipe section 102. During the adjustment process, the water flow channel 520 is always unblocked, and when the telescopic pipe section 102 is adjusted to the appropriate length, the water in the water tank 7 flows into the telescopic pipe section 102 through the fixed pipe section 101, and then flows out from the water outlet 103 of the telescopic pipe section 102, flows into the water inlet 202 of the annular water injection pipe 2 through the hose, and finally enters the annular water injection pipe 2, and irrigates the periphery of the plant roots through the water injection holes 301. Even if the length of the telescopic pipe section 102 needs to be fine-tuned during irrigation, the hose can adapt to its movement to ensure continuous and stable water flow.

[0051] The flexible hose connection solves the problem of maintaining a stable water flow channel 520 between the telescopic pipe section 102 and the annular water injection pipe 2 during the telescopic process. Compared to rigid connections, which cannot adapt to the movement of the telescopic pipe section 102, the flexibility and extensibility of the hose ensure that the inlet 202 and outlet 103 remain reliably connected during the adjustment of the telescopic pipe section 102, avoiding water leakage and reducing water waste. Simultaneously, the hose eliminates the rigid tensile force exerted on the annular water injection pipe 2 during the movement of the telescopic pipe section 102, protecting the connection between the annular water injection pipe 2 and the telescopic pipe section 102, extending the service life of components, and reducing the maintenance cost of the device. Furthermore, the hose connection is simple and convenient, easy to install and replace, further enhancing the practicality and flexibility of the device, ensuring continuous and stable irrigation operations, improving irrigation efficiency, and protecting plant growth.

[0052] For example, such as Figure 1 and Figure 6 As shown, the irrigation device also includes a fixed base 9 and a lifting rod 10. The fixed base 9 is installed at the end of the telescopic pipe section 102 away from the fixed pipe section 101. The lifting rod 10 is set on the fixed base 9. The movable end of the lifting rod 10 is fixedly connected to the outer wall of the annular water injection pipe 2. The lifting rod 10 can drive the annular water injection pipe 2 to move up and down, thereby allowing the insertion pipe 3 to be inserted into or pulled out of the soil.

[0053] In some examples, after the device is moved to the target irrigation area and the length of the telescopic pipe section 102 is adjusted, the lifting rod 10 is activated. The movable end of the lifting rod 10 extends downward, driving the annular water injection pipe 2, which is fixedly connected to it, downward as it moves. Since the insertion pipe 3 is fixed to the bottom surface of the annular water injection pipe 2, the downward movement of the annular water injection pipe 2 pushes the insertion pipe 3 into the soil. During insertion, the extension speed and stroke of the lifting rod 10 can be controlled as needed to ensure that the insertion pipe 3 is inserted to a suitable depth to meet the needs of water delivery to the outer periphery of the plant roots. After insertion, the lifting rod 10 is stopped, and irrigation begins. When the area is irrigated, the lifting rod 10 is activated, causing the movable end of the lifting rod 10 to retract upward, driving the annular water injection pipe 2 and the insertion pipe 3 upward together to pull the insertion pipe 3 out of the soil, so as to push the mobile frame 6 to the next irrigation area. Throughout the lifting process, the telescopic pipe section 102 and the annular water injection pipe 2 maintain a stable connection through a flexible hose, ensuring that the integrity of the water flow channel 520 is not affected by the up-and-down movement of the annular water injection pipe 2.

[0054] The lifting rod 10 automates the insertion and removal of the insertion tube 3 from the soil, eliminating the need for manual pressing or pulling of the annular water injection pipe 2. This significantly reduces labor costs, especially in garden areas with firm soil, allowing for easy insertion and improving the applicability of the irrigation device. By controlling the extension speed and stroke of the lifting rod 10, the insertion depth of the insertion tube 3 can be precisely controlled, avoiding problems such as shallow insertion leading to easy water evaporation and poor irrigation, or excessive insertion damaging plant roots. This further enhances the accuracy and safety of irrigation. Simultaneously, the lifting rod 10 drives the annular water injection pipe 2 to move smoothly, ensuring that the insertion tube 3 does not tilt or shift during insertion and removal. This protects the insertion tube 3 and components such as the conical end cap 4, extending the device's lifespan, reducing maintenance costs, ensuring efficient and stable irrigation operations, better conserving water resources, and promoting healthy plant growth.

[0055] For example, such as Figure 6 As shown, a water pump 11 is installed on the mobile frame 6. The water pump 11 is connected to the water tank 7, and the outlet of the water pump 11 is connected to the water supply pipe 1. The water pump 11 can provide power for the water in the water tank 7, so that the water can be delivered more smoothly through the water supply pipe 1 to the annular water injection pipe 2 and the insertion pipe 3, meeting the water pressure requirements under different irrigation scenarios.

[0056] In some examples, before irrigation, sufficient water is injected into the water tank 7 to ensure that the water pump 11 can draw water normally. Once the device is moved to the target irrigation area and the annular water injection pipe 2 surrounds the plant and the insertion pipe 3 is inserted into the soil, the water pump 11 is started. When the water pump 11 is working, it draws water from the water tank 7 and pressurizes the water using its own power, ensuring sufficient pressure for the water flow from the outlet of the water pump 11 into the water delivery pipe 1. Under pressure, the water quickly flows through the water delivery pipe 1 into the annular water injection pipe 2. A portion of the water is sprayed at appropriate pressure onto the soil surface around the plant roots through the spray holes 301 on the inner wall of the annular water injection pipe 2, while the remaining water enters the insertion pipe 3 and penetrates into the soil through the spray holes 301 on the outer wall of the insertion pipe 3, precisely targeting the outer periphery of the roots. During irrigation, the water pressure and flow rate can be controlled by adjusting the working power of the water pump 11 according to the water requirements of the plants and the soil moisture. When the soil moisture reaches a suitable level, the power of the water pump 11 is reduced to decrease the water supply; if the soil is relatively dry, the power is increased to increase the water supply. After irrigation is completed, the water pump 11 is turned off before moving and storing the device.

[0057] The water pump 11 solves the problem of insufficient water flow pressure, slow flow rate, low irrigation efficiency and uneven water outlet of the water spray hole 301 when relying solely on gravity water supply. Through the pressurization of the water pump 11, the water flow can be delivered to the water spray hole 301 at a stable and appropriate pressure, ensuring uniform water outlet of the water spray hole 301 and achieving uniform irrigation, avoiding the situation that some water spray holes 301 cannot normally outlet water due to insufficient water pressure, affecting the irrigation effect. At the same time, the water flow pressure and flow rate can be controlled by adjusting the power of the water pump 11, so that the irrigation device can adapt to the water demand of different types of plants (such as reducing the water supply for drought-tolerant plants and increasing the water supply for water-loving plants) and different soil humidity conditions, improving the versatility and flexibility of the device. In addition, the addition of the water pump 11 makes the water flow in the water delivery pipe 1 and the insertion pipe 3 more smooth, reducing the risk of pipe blockage caused by slow water flow speed, especially for irrigation water containing a small amount of impurities. Higher water flow speed can disperse impurities and avoid their accumulation and blockage at the water spray hole 301, ensuring long-term stable operation of the irrigation device, reducing maintenance work, further improving irrigation efficiency, saving water resources, ensuring that plants obtain sufficient and appropriate water supply, and promoting plant growth.
