Description

Technical Field

[0001] This invention belongs to the field of forest seedling planting technology, specifically relating to an irrigation device for planting economic forest seedlings. Background Technology

[0002] As a fruit tree variety with high market demand and economic value, irrigation is a crucial aspect of pomegranate cultivation. The pomegranate tree's growth cycle includes several key irrigation periods, such as the pre-frost irrigation, the budding irrigation, and the post-flowering fruit-promoting irrigation. The water supply during these periods directly affects the healthy growth, flowering, fruiting, yield, and quality of the pomegranate tree. However, some problems with traditional irrigation methods seriously affect the growth efficiency of pomegranate trees and the quality of the fruit.

[0003] Specifically, firstly, pomegranate seedlings have shallow root systems (mainly concentrated 10-20cm below the soil surface). Traditional flood irrigation or fixed sprinkler irrigation easily causes surface soil compaction, hindering water infiltration and leading to localized waterlogging. This results in the roots being in a state of chronic oxygen deficiency, inducing root rot. Currently, soil loosening operations mostly rely on manual labor or independent machinery, which are separate from the irrigation process. This increases labor costs and fails to improve soil aeration simultaneously during watering.

[0004] Secondly, economic forest seedlings are often irregularly distributed due to differences in species or terrain limitations. Traditional irrigation equipment (such as fixed sprinkler belts or drip irrigation networks) is difficult to dynamically adapt to the location of the seedlings, resulting in an expansion of ineffective irrigation areas. Although existing mobile irrigation equipment can adjust the coverage area, it lacks precise positioning capabilities and cannot optimize the irrigation path in real time according to the actual distribution density of the seedlings, thus restricting the efficiency of large-scale planting.

[0005] Furthermore, during the seedling growth period, fertilizers (such as NPK compound fertilizer) or pesticides (such as fungicides) need to be applied regularly. Traditional operation mode usually separates irrigation from fertilization / spraying, resulting in the two processes being duplicated and requiring manpower. Summary of the Invention

[0006] The purpose of this invention is to provide an irrigation device for planting economic forest seedlings, which can add medicines or fertilizers to the main pipe when needed to meet the different needs of the seedlings. After the ground anchor component is driven into the soil, it can make the deep soil and the air on the soil surface come into contact, so as to avoid root rot caused by insufficient aeration. After long-term irrigation, it can also break up the compacted soil in the irrigation area to prevent the soil from becoming compacted due to long-term irrigation, which would lead to insufficient aeration and affect the growth of the seedlings.

[0007] The specific technical solution adopted by this invention is as follows:

[0008] An irrigation device for planting economic forest seedlings includes a main pipe, with a pesticide application pipe connected to the middle of the main pipe, and further includes:

[0009] A ground bolster assembly is mounted on a main pipe. The ground bolster assembly includes a branch pipe, a diversion pipe, an outer wall pipe, an isolation net, a fixing stake, and a venting net. The branch pipe is connected to the middle of the main pipe, and the other end of the branch pipe is connected to the diversion pipe. The outer wall pipe is fixedly connected to the outer ring of both the upper and lower ends of the diversion pipe. An isolation net is fixedly connected to the outer side of the outer wall pipe. A fixing stake is fixedly connected to the side of the isolation net closest to the inner cavity of the outer wall pipe. The fixing stake is fixedly connected to the outer side of the diversion pipe. A venting net is fixedly connected to the outer side of the upper end of the outer wall pipe.

[0010] An opening and closing assembly is mounted on the fixed pile and the diversion pipe;

[0011] A puncture assembly is assembled on a fixed post, an opening and closing assembly, and an outer wall tube. The puncture assembly includes a puncture needle, which is slidably connected inside the fixed post, and the pointed end of the puncture needle penetrates the isolation net.

[0012] When the outer wall tube is placed inside the soil, multiple sets of isolation nets isolate the deep soil outside the outer wall tube. At this time, the deep soil is connected to the air on the soil surface through the isolation net, the inner cavity of the outer wall tube, and the air-permeable net. The puncture needle can extend out of the outer wall tube to puncture the hardened soil in the irrigation area.

[0013] In a preferred embodiment, the upper end of the dosing tube is fixedly connected to a liquid storage box and a sealed chamber, and the lower ends of the liquid storage box and the sealed chamber are interconnected with the dosing tube. A dosing wheel is rotatably connected to the lower end of the liquid storage box that is connected to the dosing tube. The shaft of the dosing wheel passes through the liquid storage box and the dosing tube and extends into the sealed chamber, and is rotatably connected to its inner wall. A fan wheel is fixedly connected to the outer edge of the shaft of the dosing wheel located in the sealed chamber, and the lower end of the fan wheel extends into the dosing tube.

[0014] In a preferred embodiment, the outer edge of the delivery wheel is provided with two sets of grooves, and the grooves are located at both ends of the cross-sectional diameter of the delivery wheel.

[0015] In a preferred embodiment, the ground nut assembly further includes multiple sets of water nozzles, which are evenly connected to the outer edge of the diversion pipe, and the outlet ends of the multiple sets of water nozzles all penetrate the outer wall pipe and are located on the outer edge of the outer wall pipe.

[0016] In a preferred embodiment, the upper end of the diversion pipe is provided with an annular groove, and the lower end of the diversion pipe is provided with multiple sets of vertically penetrating slots, which are not connected to the channel in the inner cavity of the diversion pipe used for transporting water.

[0017] In a preferred embodiment, the opening and closing assembly includes a sealing block, a first spring, a pull rope, a guide rod, and a lifting ring. The sealing block is slidably connected to the outer edge of the fixed pile. The sealing block has four sets of grooves on the side near the diversion pipe, and a first spring is fixedly connected to each groove. The other ends of the four sets of first springs are fixedly connected to the outer edge of the diversion pipe. Pull ropes are fixedly connected to the upper and lower ends of the sealing block near the diversion pipe. The other ends of the pull ropes extend into the through groove of the diversion pipe, and a guide rod is fixedly connected to the other end of the pull rope. The guide rod is movably sleeved in the through groove of the diversion pipe. The upper end of the guide rod penetrates the through groove of the diversion pipe and extends into the annular groove at the upper end of the diversion pipe. A lifting ring is fixedly connected to the upper end of the guide rod, and the lifting ring is movably sleeved in the annular groove.

[0018] In a preferred embodiment, the opening and closing assembly further includes a positioning groove, a limiting tube, a positioning plate, and a second spring. The positioning groove is formed on the outer edge of the upper end of the lifting ring. Multiple sets of limiting tubes are fixedly connected to the upper end of the outer wall tube. Positioning plates are slidably connected to the inner cavities of the multiple sets of limiting tubes. The positioning plates are inserted into the positioning groove. A second spring is fixedly connected to one end of the positioning plate that extends into the inner cavity of the limiting tube. The other end of the second spring is fixedly connected to the middle of the inner cavity of the limiting tube. The positioning plate and the positioning groove are mutually adapted.

[0019] In a preferred embodiment, the puncture assembly further includes a drive block, a lifting frame, and a connecting block. The drive block is fixedly connected to one end of the puncture needle near the shunt tube. A downward through groove is provided in the middle of the sealing block, and the lifting frame is slidably connected in the through groove. A connecting block is fixedly connected in the middle of the lifting frame. The connecting block passes through the sealing block and the fixing post and is movably inserted into the drive block. A through groove that is compatible with the connecting block is provided on the drive block.

[0020] In a preferred embodiment, the puncture assembly further includes a lifting plate, a double-layer guide groove, and a limiting block. The lifting plate is fixedly connected to the top of the lifting frame. The upper end of the outer wall tube is provided with a double-layer guide groove. The upper end of the lifting plate extends into the double-layer guide groove, and both sides of the upper end of the lifting plate are slidably connected to the limiting block. The portions of the limiting block extending out of the lifting plate are slidably connected to the double-layer guide groove.

[0021] In a preferred embodiment, the distance between the upper and lower sides of the double-layer guide groove is greater than the height of the drive block, so that when the lifting plate and its matching limiting block are located in the upper guide groove of the double-layer guide groove, the connecting block will detach from the drive block, and when it is located in the lower guide groove, the connecting block will insert into the drive block.

[0022] The technical effects achieved by this invention are as follows:

[0023] The drug-adding tube of the present invention can add drugs or fertilizers into the main tube when needed, thereby meeting the different needs of forest seedlings and improving practicality. In daily use, drugs or fertilizers are placed in the storage part at the upper end of the drug-adding tube. Then, when the water in the main tube is flowing, the flowing water will drive the driving part of the inner cavity of the drug-adding tube to rotate, and drive the conveying part of the inner cavity of the drug-adding tube to rotate, sending the drugs or fertilizers in the storage part into the main tube to mix with the water in the main tube, and then delivering them into the soil through the ground plug assembly, realizing automatic fertilization or drug addition during forest seedling irrigation.

[0024] The ground anchor component and the opening and closing component of the present invention can allow the deep soil to communicate and contact with the air on the soil surface after the ground anchor component is inserted into the soil, thus avoiding root rot caused by insufficient aeration. Before irrigation, the ground anchor component is inserted at a suitable distance from the seedling according to the needs of the irrigation site. After the outer wall tube is inserted into the soil, the moving part of the opening and closing component is pulled up, which moves the sealing part of the opening and closing component to connect the isolation net with the inner cavity of the outer wall tube. This allows water vapor in the deep soil to be discharged to the surface through the isolation net, the outer wall tube and the aeration net, thus avoiding root rot caused by excessive water vapor in the soil, which would affect the growth of the seedlings.

[0025] The opening / closing component and puncture component of this invention can disperse the compacted soil in the irrigated area after long-term irrigation, avoiding insufficient aeration caused by soil compaction due to long-term irrigation, which would affect the growth of seedlings. After long-term irrigation, if the soil in the irrigated area becomes compacted, the moving part of the puncture component is pressed down to connect with the puncture needle. Then, the moving part of the opening / closing component is released, causing the sealing part of the opening / closing component and the puncture needle to move together, driving the puncture needle to extend outward and penetrate into the soil. Then, the outer wall tube is rotated, allowing the extended puncture needle to disperse the surrounding compacted soil through rotational movement, making the soil loose. Attached Figure Description

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0049] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0050] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0051] Please see the appendix Figure 1 , Figures 5 to 6 and Figure 13 As shown, this embodiment provides an irrigation device for planting economic forest seedlings, including a main pipe 10, with a pesticide application pipe 11 connected to the middle of the main pipe 10, and also including:

[0052] The ground nut assembly 20 is assembled on the main pipe 10. The ground nut assembly 20 includes a branch pipe 21, a diversion pipe 22, an outer wall pipe 24, an isolation net 25, a fixing post 26, and a venting net 27. The branch pipe 21 is connected to the middle of the main pipe 10, and the other end of the branch pipe 21 is connected to the diversion pipe 22. The outer wall pipe 24 is fixedly connected to the outer ring of the upper and lower ends of the diversion pipe 22. Multiple sets of ventilation grooves are opened on the outer side of the outer wall pipe 24, and the isolation net 25 is fixedly connected in the ventilation grooves. The fixing post 26 is fixedly connected to the side of the multiple sets of isolation nets 25 near the inner cavity of the outer wall pipe 24. The fixing post 26 is fixedly connected to the outer side of the diversion pipe 22. Multiple sets of ventilation grooves are also opened on the outer side of the upper end of the outer wall pipe 24, and the venting net 27 is fixedly connected in the ventilation grooves.

[0053] Opening and closing assembly 30 is assembled on the fixed pile 26 and the diversion pipe 22;

[0054] The puncture assembly 40 is assembled on the fixed post 26, the opening and closing assembly 30 and the outer wall tube 24. The puncture assembly 40 includes a puncture needle 41, which is slidably connected in the fixed post 26. The tip of the puncture needle 41 penetrates the isolation net 25. The isolation net 25 has a through groove in the middle, which communicates with the inner cavity of the fixed post 26. The puncture needle 41 extends outward through the through groove.

[0055] When the outer wall tube 24 is placed inside the soil, multiple sets of isolation nets 25 isolate the deep soil outside the outer wall tube 24. At this time, the deep soil is connected to the air on the soil surface through the isolation nets 25, the inner cavity of the outer wall tube 24 and the air-permeable net 27. The connected air ensures that the water vapor in the deep soil can be released in time, preventing the roots of the seedlings from rotting. The piercing needle 41 can extend out of the outer wall tube 24 to pierce the compacted soil in the irrigation area, so that the compacted soil caused by long-term irrigation can be dispersed by rotating the outer wall tube 24 and the piercing needle 41, restoring the permeability of the deep soil.

[0056] It should be noted that in this embodiment, multiple sets of irrigation components and ground anchor components 20 can be set. Multiple sets of ground anchor components 20 are connected to the same main pipe 10. According to the irrigation needs, multiple sets of ground anchor components 20 are inserted into the appropriate irrigation positions for the seedlings (to avoid the irrigation area being too close to the seedlings, which could lead to root rot). By installing multiple sets of irrigation devices in the seedling planting area, the seedling planting area can be divided into zones by irrigation components, so that each zone can be fertilized or sprayed according to the needs. This avoids the situation where a large area of ​​seedling planting area is irrigated by one irrigation component at the same time, which would prevent the fertilization or spraying from being adjusted according to the growth of different seedlings.

[0057] The outer wall tube 24 is provided with a handle on the upper outer side to facilitate the insertion, removal and rotation of the outer wall tube 24 into the soil, and a pointed cone is provided at the lower end of the outer wall tube 24 to facilitate the insertion into the soil.

[0058] In this embodiment, during installation, the outer wall tube 24 is inserted at a suitable irrigation distance from the seedlings. Then, the opening and closing component 30 is controlled to connect the inner cavity of the outer wall tube 24 with the isolation net 25. This allows moisture from the deep soil to be discharged to the surface through the isolation net 25 and the outer wall tube 24 via the aeration net 27, preventing excessive moisture from causing root rot. During irrigation, pesticides or fertilizers can be added to the water source via the pesticide addition tube 11, achieving automatic fertilization or pesticide application during seedling irrigation. If the soil becomes compacted due to long-term irrigation, the opening and closing component 30 drives the piercing needle 41 to extend from the outer wall tube 24 and penetrate the soil. The outer wall tube 24 is then rotated to break up the surrounding compacted soil, preventing impaired soil aeration.

[0059] Secondly, please refer to again Figures 1 to 3The upper end of the drug-adding tube 11 is fixedly connected to the liquid storage box 12 and the sealed chamber 13 respectively, and the lower ends of the liquid storage box 12 and the sealed chamber 13 are connected to the drug-adding tube 11. The lower end of the liquid storage box 12 connected to the drug-adding tube 11 is rotatably connected to the drug delivery wheel 14 through the ball bearing. The shaft of the drug delivery wheel 14 passes through the liquid storage box 12 and the drug-adding tube 11 and extends into the sealed chamber 13, and is rotatably connected to its inner wall through the ball bearing. The outer edge of the shaft of the drug delivery wheel 14 located in the sealed chamber 13 is fixedly connected to the fan wheel 15, and the lower end of the fan wheel 15 extends into the drug-adding tube 11.

[0060] Two sets of grooves are provided on the outer edge of the delivery wheel 14, and the grooves are located at both ends of the cross-sectional diameter of the delivery wheel 14, so as to ensure that two sets of solutions are delivered through the grooves every time the delivery wheel 14 rotates once, thereby improving stability.

[0061] It should be noted that an observation slot is provided on the outside of the liquid storage box 12, and an observation plate is fixedly connected in the observation slot. The observation plate is made of one of the following materials: PVC, tempered glass or other transparent materials. In this embodiment, the material of the observation plate is preferably tempered glass.

[0062] The upper end of the liquid storage box 12 is provided with an addition port, and the addition port is connected to the inner cavity of the liquid storage box 12. In this embodiment, the fertilizer added to the liquid storage box 12 is preferably liquid fertilizer.

[0063] In this embodiment, when watering, fertilizer or pesticide is added to the storage box 12. When water flows in the main pipe 10, it drives the fan wheel 15 to rotate. The rotating fan wheel 15 drives the delivery wheel 14 to rotate as well. The pesticide or fertilizer in the storage box 12 is delivered into the main pipe 10 through the groove on the delivery wheel 14, so that it mixes with the water in the main pipe 10, thereby realizing automatic fertilization or pesticide application during watering.

[0064] Secondly, please refer to again Figures 4 to 6 and Figure 11 The ground nut assembly 20 also includes multiple sets of water spray heads 23, which are evenly connected to the outer edge of the diversion pipe 22. The water outlets of the multiple sets of water spray heads 23 all penetrate the outer wall pipe 24 and are located on the outer edge of the outer wall pipe 24.

[0065] The upper end of the diversion pipe 22 is provided with an annular groove, and the lower end of the diversion pipe 22 is provided with multiple sets of vertically penetrating grooves. The vertically penetrating grooves are not connected to the channel in the inner cavity of the diversion pipe 22 used for transporting water, so as to prevent the water transported in the diversion pipe 22 from leaking out through the grooves and affecting the aeration effect of irrigation.

[0066] In this embodiment, during irrigation, the water in the main pipe 10 flows into the spray head 23 through the branch pipe 21 and the branch pipe 22, and then flows into the soil through the spray head 23 to irrigate the seedlings. This also avoids water soaking above the roots of the seedlings, which could cause the roots to rot.

[0067] Secondly, please refer to again Figures 7 to 12 The opening and closing assembly 30 includes a sealing block 31, a first spring 32, a pull rope 33, a guide rod 34, and a lifting ring 35. The sealing block 31 is slidably connected to the outer edge of the fixed pile 26. Four sets of grooves are formed on the side of the sealing block 31 near the diversion pipe 22, and each groove is fixedly connected to a first spring 32. The other ends of the four sets of first springs 32 are fixedly connected to the outer edge of the diversion pipe 22. Pull ropes 33 are fixedly connected to the upper and lower ends of the sealing block 31 near the diversion pipe 22, and the other ends of the pull ropes 33 extend into the diversion pipe 22. Inside the through groove, and the other end of the pull rope 33 is fixedly connected to a guide rod 34. The guide rod 34 is movably sleeved in the through groove of the diverter pipe 22. The upper end of the guide rod 34 passes through the through groove of the diverter pipe 22 and extends into the annular groove at the upper end of the diverter pipe 22. The upper end of the guide rod 34 is fixedly connected to a lifting ring 35. The lifting ring 35 is movably sleeved in the annular groove. The upper end of the lifting ring 35 is provided with a handle. The outer side of the lifting ring 35 is provided with a limiting protrusion (not shown in the figure) to make the lifting ring 35 slide up and down only in the annular groove and not rotate.

[0068] The opening and closing assembly 30 also includes a positioning groove 36, a limiting tube 37, a positioning plate 38, and a second spring 39. The positioning groove 36 is opened on the outer edge of the upper end of the lifting ring 35. Multiple sets of limiting tubes 37 are fixedly connected to the upper end of the outer wall tube 24. The inner cavity of each set of limiting tubes 37 is slidably connected to a positioning plate 38. The positioning plate 38 is inserted into the positioning groove 36. One end of the positioning plate 38 that extends into the inner cavity of the limiting tube 37 is fixedly connected to a second spring 39. The other end of the second spring 39 is fixedly connected to the middle of the inner cavity of the limiting tube 37. The positioning plate 38 and the positioning groove 36 are mutually adapted. The upper end of the lifting ring 35 is provided with a ramp, and the ramp is in contact with the lower end of the positioning plate 38, so that during the rising process, the lifting ring 35 can use the ramp at its upper end to push the positioning plate 38 back into the limiting tube 37.

[0069] It should be noted that the first spring 32 is a high-strength spring, and the pull rope 33 is preferably a steel wire rope, in order to improve strength and prevent the pull rope 33 from breaking and affecting the use of the device;

[0070] A handle is provided on the top of the positioning plate 38, and the handle is slidably connected to the upper end of the limiting tube 37, so that the positioning plate 38 can be easily driven to move using the handle.

[0071] In this embodiment, before the outer wall tube 24 is inserted into the soil, the sealing block 31 is attached to the inside of the isolation net 25 to prevent soil from the outside from entering the inner cavity of the outer wall tube 24 through the isolation net 25 when it is inserted into the soil. After the outer wall tube 24 is fully inserted into the soil, the lifting ring 35 is pulled up to drive the guide rod 34 to rise. Then the guide rod 34 drives the pull rope 33 to move, pulling the sealing block 31 closer to the diversion pipe 22, so that the sealing block 31 is separated from the isolation net 25. At this time, the water vapor in the deep soil can be introduced into the inner cavity of the outer wall tube 24 through the isolation net 25 and discharged to the surface through the ventilation net 27, so as to avoid excessive water vapor in the soil from causing the roots of the seedlings to rot and affecting their growth. During the upward movement of the lifting ring 35, the ramp at its upper end will push the positioning plate 38 into the limiting tube 37. When the lifting ring 35 rises to the specified height, the positioning groove 36 will align with the positioning plate 38. At this time, the second spring 39 will quickly rebound, pushing the positioning plate 38 into the positioning groove 36 to fix the lifting ring 35, thereby maintaining the open state of the isolation net 25.

[0072] Please refer to it again. Figures 13 to 18 The puncture assembly 40 also includes a drive block 42, a lifting frame 43, and a connecting block 44. The drive block 42 is fixedly connected to one end of the puncture needle 41 near the diversion tube 22. A through groove is provided in the middle of the sealing block 31, and the lifting frame 43 is slidably connected in the through groove. The connecting block 44 is fixedly connected in the middle of the lifting frame 43. The connecting block 44 passes through the sealing block 31 and the fixing post 26 and is movably inserted into the drive block 42. A through groove that is compatible with the connecting block 44 is provided on the drive block 42. A magnetic plate is fixedly connected to the side of the drive block 42 near the diversion tube 22, and a magnetic plate that is compatible with it is provided in the inner cavity of the fixing post 26. In normal state, the drive block 42 will be attracted to the inner cavity of the fixing post 26 by the magnetic plate, so that the drive block 42 cannot slide arbitrarily.

[0073] The puncture assembly 40 also includes a lifting plate 45, a double-layer guide groove 46, and a limiting block 47. The lifting plate 45 is fixedly connected to the top of the lifting frame 43. The upper end of the outer wall tube 24 is provided with a double-layer guide groove 46. The upper end of the lifting plate 45 extends into the double-layer guide groove 46, and the two sides of the upper end of the lifting plate 45 are slidably connected to the limiting block 47. The part of the limiting block 47 extending out of the lifting plate 45 is slidably connected to the double-layer guide groove 46. The double-layer guide groove 46 is composed of two sets of straight guide grooves, upper and lower.

[0074] The distance between the upper and lower sides of the double-layer guide groove 46 is greater than the height of the drive block 42. When the lifting plate 45 and its matching limiting block 47 are located in the upper guide groove of the double-layer guide groove 46, the connecting block 44 will disengage from the drive block 42. When it is located in the lower guide groove, the connecting block 44 will insert into the drive block 42.

[0075] It should be noted that a handle is provided above the limiting block 47, and the handle is slidably connected to the lifting plate 45 so that the limiting block 47 can be moved by pulling the handle, making it easy to retract into the lifting plate 45.

[0076] In this embodiment, under normal conditions, the limiting block 47 slides within the upper guide groove of the double-layer guide groove 46, and the connecting block 44 is not connected to the driving block 42. However, after long-term irrigation, if the soil hardens, the limiting block 47 is retracted into the lifting plate 45. Subsequently, the lifting plate 45 descends, causing the connecting block 44 to insert into the driving block 42. Immediately afterwards, the limiting block 47 is pushed outward into the lower guide groove of the double-layer guide groove 46, and then the restriction on the lifting ring 35 is released. At this time, the first spring 32 quickly rebounds, pushing the dense... The sealing block 31 moves, which in turn drives the lifting frame 43 and connecting block 44 to move, and drives the driving block 42 and puncture needle 41 to move, so that the puncture needle 41 extends out of the outer wall tube 24 and inserts into the soil. Then, the outer wall tube 24 rotates, which drives the puncture needle 41 to rotate together, stirring up the surrounding compacted soil to avoid affecting the soil's permeability. During the stirring process, the sealing block 31 always moves towards the isolation net 25 to prevent a large amount of stirred soil from entering the outer wall tube 24 and affecting the permeability.

[0077] The working principle of this invention is as follows: the outer wall pipe 24 is inserted at a suitable irrigation distance from the seedlings, and then the lifting ring 35 is pulled up, which moves the guide rod 34 and the pull rope 33, pulling the sealing block 31 closer to the diversion pipe 22, so that the sealing block 31 is detached from the isolation net 25. At this time, the water vapor in the deep soil can be introduced into the inner cavity of the outer wall pipe 24 through the isolation net 25 and discharged to the surface through the ventilation net 27. After the lifting ring 35 rises, the positioning plate 38 will be inserted into the positioning groove 36 to fix the lifting ring 35, thereby maintaining the open state of the isolation net 25. During irrigation, fertilizer or pesticide solution is added to the storage box 12. As water flows through the main pipe 10, it drives the fan wheel 15 to rotate. The rotating fan wheel 15 drives the delivery wheel 14 to rotate as well. The pesticide solution or fertilizer in the storage box 12 is delivered into the main pipe 10 through the groove on the delivery wheel 14, so that it mixes with the water in the main pipe 10. The water in the main pipe 10 flows into the sprinkler head 23 through the branch pipe 21 and the branch pipe 22, and then flows into the soil through the sprinkler head 23 to irrigate the seedlings. After prolonged irrigation, if the soil becomes compacted, the limiting block 47 is retracted into the lifting plate 45. The lifting plate 45 then descends, allowing the connecting block 44 to insert into the driving block 42. Next, the limiting block 47 is pushed outward into the lower guide groove of the double-layer guide groove 46. Then, the restriction on the lifting ring 35 is released. At this time, the first spring 32 quickly rebounds, pushing the sealing block 31 and the connecting block 44 to move, and driving the driving block 42 and the puncture needle 41 to move, so that the puncture needle 41 extends out of the outer wall tube 24 and inserts into the soil. Then, the outer wall tube 24 is rotated, causing the puncture needle 41 to rotate together, stirring up the compacted soil around it to avoid affecting the soil's permeability. During the stirring process, the sealing block 31 always moves towards the isolation net 25 to prevent a large amount of stirred soil from entering the outer wall tube 24 and affecting the permeability.
