Description

Technical Field

[0001] The present invention belongs to the technical field of forest seedling planting, and particularly relates to an irrigation device for planting economic forest seedlings. Background Art

[0002] As a fruit tree variety with a large market demand and high economic value, irrigation is a crucial link in the planting process of pomegranates. During the growth cycle of pomegranate trees, there are multiple critical watering periods, including frozen water, budding water, and fruit-promoting water after flowering. The water supply during these periods is directly related to the healthy growth, flowering, fruiting, yield, and quality of pomegranate trees. However, some problems exist in traditional irrigation methods, seriously affecting the growth efficiency of pomegranate trees and the quality of fruits.

[0003] Specifically, first, the root systems of pomegranate seedlings are shallowly distributed (mainly concentrated 10 - 20 cm below the ground surface). Traditional flood irrigation or fixed sprinkler irrigation easily causes surface soil compaction, hinders water infiltration, forms local waterlogging, and leads to the root systems being in an anoxic state for a long time, inducing root rot. Existing soil loosening operations mostly rely on manual labor or independent machinery, which is separated from the irrigation process, increasing both labor costs and being unable to improve soil air permeability synchronously during watering.

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

[0005] Furthermore, during the growth period of seedlings, fertilizers (such as nitrogen, phosphorus, and potassium compound fertilizers) or pesticides (such as fungicides) need to be applied regularly. The traditional operation mode usually separates irrigation from fertilization / pesticide spraying, resulting in the two processes repeatedly occupying labor. Summary of the Invention

After long-term irrigation, if the soil in the irrigation area is compacted, press down the moving part of the puncture assembly to connect it with the puncture needle. Subsequently, release the moving part of the opening and closing assembly, so that the sealing part of the opening and closing assembly and the puncture needle move together, driving the puncture needle to extend and penetrate into the soil. Then rotate the outer wall pipe, so that the extended puncture needle can disperse the surrounding compacted soil through rotational movement, making the soil loose. Description of the Drawings

[0048] In the following description, numerous specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0049] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0050] Furthermore, the present invention is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views showing the device structure are enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0051] Please refer to the attached 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. A medicine adding pipe 11 is connected to the middle of the main pipe 10. It further includes:

[0052] A ground bolt assembly 20, which is assembled on the main pipe 10. The ground bolt assembly 20 includes a branch pipe 21, a shunt pipe 22, an outer wall pipe 24, an isolation net 25, a fixing pile 26, and a ventilation net 27. The branch pipe 21 is connected to the middle of the main pipe 10. The other end of the branch pipe 21 is connected to a shunt pipe 22. Outer wall pipes 24 are fixedly connected to the outer circles of the upper and lower ends of the shunt pipe 22. Multiple groups of ventilation slots are opened on the outer side of the outer wall pipe 24, and an isolation net 25 is fixedly connected in the ventilation slots. Multiple groups of isolation nets 25 are fixedly connected to a fixing pile 26 on the side close to the inner cavity of the outer wall pipe 24. The fixing pile 26 is fixedly connected to the outer side of the shunt pipe 22. Multiple groups of ventilation slots are also opened on the outer side of the upper end of the outer wall pipe 24, and a ventilation net 27 is fixedly connected in the ventilation slots.

[0053] An opening and closing assembly 30, which is assembled on the fixing pile 26 and the shunt pipe 22;

[0054] The puncture assembly 40 is assembled and fixed to the fixing pile 26, the opening and closing assembly 30 and the outer wall pipe 24. The puncture assembly 40 includes a puncture needle 41 which is slidably connected within the fixing pile 26, and the pointed end of the puncture needle 41 penetrates through the isolation net 25. A through groove is formed in the middle of the isolation net 25, and the through groove communicates with the inner cavity of the fixing pile 26. The puncture needle 41 extends outwards through the through groove.

[0055] Among them, when the outer wall pipe 24 is placed in the soil, multiple groups of isolation nets 25 isolate the deep soil outside the outer wall pipe 24. At this time, the deep soil is communicated with the air on the soil surface through the isolation nets 25, the inner cavity of the outer wall pipe 24 and the air permeable net 27. Through the communicated air, the water vapor in the deep soil can be dissipated in time to avoid the root rot of forest seedlings. The puncture needle 41 can extend out of the outer wall pipe 24 to pierce the caked soil in the irrigation area, so that the caked soil generated by long-term irrigation can be dispersed by rotating the outer wall pipe 24 and the puncture needle 41, and the air permeability of the deep soil can be restored.

[0056] It should be noted that in this embodiment, multiple groups of irrigation assemblies and ground bolt assemblies 20 can be provided. Multiple groups of ground bolt assemblies 20 are connected to the same main pipe 10. According to the irrigation requirements, multiple groups of ground bolt assemblies 20 are inserted into the positions suitable for irrigating forest seedlings (to avoid root rot caused by the irrigation area being too close to the forest seedlings). By installing multiple groups of irrigation devices in the forest seedling planting area, the forest seedling planting area can be divided by the irrigation assembly, so that each area can be fertilized or medicated according to the needs, avoiding the situation that a large area of forest seedling planting area is irrigated by a single irrigation assembly at the same time, resulting in the inability to adjust fertilization or medicament application according to the growth conditions of different forest seedlings.

[0057] A handle is provided on the outer side of the upper end of the outer wall pipe 24, which is convenient for operations such as inserting the outer wall pipe 24 into the soil, pulling it out, and rotating it. And a pointed cone is provided at the lower end of the outer wall pipe 24, which is convenient for the operation of inserting into the soil.

[0058] In this embodiment, when installing the device, the outer wall pipe 24 is inserted into a suitable irrigation distance from the forest seedlings. Then, the opening and closing assembly 30 is controlled to connect the inner cavity of the outer wall pipe 24 with the isolation net 25, so that the water vapor in the deep soil can be discharged from the air permeable net 27 through the isolation net 25 and the outer wall pipe 24 to the ground surface, avoiding root rot caused by excessive water vapor. When irrigating, drugs or fertilizers can be added to the water source through the medicine adding pipe 11 to achieve automatic fertilization or medicament application during the irrigation of forest seedlings. Under long-term irrigation, when the soil cakes, the opening and closing assembly 30 drives the puncture needle 41 to extend out of the outer wall pipe 24 and plunge into the soil, and then the outer wall pipe 24 is rotated to disperse the surrounding caked soil, avoiding affecting the air permeability of the soil.

[0059] Secondly, please refer to again Figures 1 to 3, the upper ends of the medicine adding pipes 11 are respectively fixedly connected with a liquid storage box 12 and a sealing chamber 13, and the lower ends of the liquid storage box 12 and the sealing chamber 13 are both communicated with the medicine adding pipes 11. The part where the lower end of the liquid storage box 12 is communicated with the medicine adding pipe 11 is rotatably connected with a medicine delivery wheel 14 through a ball bearing. The rotating shaft of the medicine delivery wheel 14 penetrates through the liquid storage box 12 and the medicine adding pipe 11 and extends into the sealing chamber 13, and is rotatably connected to the inner wall thereof through a ball bearing. And the outer edge of the rotating shaft of the medicine delivery wheel 14 located in the sealing chamber 13 is fixedly connected with a wind wheel 15, and the lower end of the wind wheel 15 extends into the medicine adding pipe 11;

[0060] Two groups of grooves are formed in the outer edge of the medicine delivery wheel 14, and the grooves are located at both ends of the cross-sectional diameter of the medicine delivery wheel 14, ensuring that two groups of solutions are sent out through the grooves every time the medicine delivery wheel 14 rotates one week, thereby improving stability.

[0061] It should be noted that an observation groove is formed in the outer side of the liquid storage box 12, and an observation plate is fixedly connected in the observation groove. And the material of the observation plate is 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] An adding port is formed in the upper end of the liquid storage box 12, and the adding port is communicated with the inner cavity of the liquid storage box 12. And in this embodiment, the fertilizer added in the liquid storage box 12 is preferably liquid fertilizer.

[0063] In this embodiment, when watering, fertilizers or liquid medicines are added into the liquid storage box 12. When water flows in the main pipe 10, it will push the wind wheel 15 to rotate, and the rotating wind wheel 15 will drive the medicine delivery wheel 14 to rotate together. The liquid medicine or fertilizer in the liquid storage box 12 will be transported into the main pipe 10 through the grooves on the medicine delivery wheel 14, so as to be mixed with the water source in the main pipe 10, realizing automatic fertilization or drug application during watering.

[0064] Secondly, please refer to Figures 4 to 6 and Figure 11 again. The ground bolt assembly 20 further includes a plurality of spray heads 23. The plurality of spray heads 23 are uniformly communicated with the outer edge of the shunt pipe 22. The water outlet ends of the plurality of spray heads 23 all penetrate through the outer wall pipe 24 and are located on the outer edge of the outer wall pipe 24;

[0065] An annular groove is formed in the upper end of the shunt pipe 22, and a plurality of through slots that penetrate up and down are formed in the position of the shunt pipe 22 below the annular groove. And the through slots that penetrate up and down are not communicated with the channel for transporting the water source in the inner cavity of the shunt pipe 22, preventing the water source transported in the shunt pipe 22 from leaking out through the through slots and affecting the ventilation effect of watering.

[0066] In this embodiment, during watering, the water in the main pipe 10 will flow into the sprinkler head 23 through the branch pipe 21 and the shunt pipe 22, and flow into the soil through the sprinkler head 23 to achieve watering of the forest seedlings, and also avoid water soaking above the roots of the forest seedlings, which may cause the roots of the forest seedlings to rot.

[0067] Secondly, please refer to Figures 7 to 12 , the opening and closing assembly 30 includes a sealing block 31, a first spring 32, a pulling 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 groups of grooves are formed on one side of the sealing block 31 close to the shunt pipe 22, and a first spring 32 is fixedly connected in each groove. The other ends of the four first springs 32 are fixedly connected to the outer edge of the shunt pipe 22. Pulling ropes 33 are fixedly connected to the upper and lower ends of the sealing block 31 on the side close to the shunt pipe 22. The other ends of the pulling ropes 33 extend into the through groove of the shunt pipe 22, and a guide rod 34 is fixedly connected to the other ends of the pulling ropes 33. The guide rod 34 is movably sleeved in the through groove of the shunt pipe 22. The upper end of the guide rod 34 penetrates through the through groove of the shunt pipe 22 and extends into the annular groove at the upper end of the shunt pipe 22, and a lifting ring 35 is fixedly connected to the upper end of the guide rod 34. The lifting ring 35 is movably sleeved in the annular groove. A handle is provided at the upper end of the lifting ring 35, and a limiting convex block (not shown in the figure) is provided on the outer side of the lifting ring 35, which is designed to enable the lifting ring 35 to only slide up and down in the annular groove and cannot rotate;

[0068] The opening and closing assembly 30 further includes a positioning groove 36, a limiting tube 37, a positioning plate 38 and a second spring 39. The positioning groove 36 is formed on the outer edge of the upper end of the lifting ring 35. Multiple groups of limiting tubes 37 are fixedly connected to the upper end of the outer wall tube 24. A positioning plate 38 is slidably connected in the inner cavity of each of the multiple groups of limiting tubes 37. The positioning plate 38 is inserted into the positioning groove 36. A second spring 39 is fixedly connected to the end of the positioning plate 38 extending into the inner cavity of the limiting tube 37. 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. A slope is formed at the upper end of the lifting ring 35, and the slope is in contact with the lower end of the positioning plate 38, so that when the lifting ring 35 rises, the slope at its upper end can be used to push the positioning plate 38 back into the limiting tube 37.

[0069] It should be noted that the first spring 32 is a strong spring, and the pulling rope 33 is preferably a steel wire rope, aiming to improve the strength and avoid the breakage of the pulling rope 33, which may affect the use of the device;

[0070] A handle is provided above the positioning plate 38, and the handle is slidably connected to the upper end of the limiting tube 37, aiming to facilitate the driving of the positioning plate 38 to move by using the handle.

[0071] In this embodiment, before the outer wall pipe 24 is inserted into the soil, the sealing block 31 fits against the inner side of the isolation net 25 to prevent external soil from entering the inner cavity of the outer wall pipe 24 through the isolation net 25 when it is inserted into the soil. After the outer wall pipe 24 is completely inserted into the soil, the lifting ring 35 is pulled upward to drive the guide rod 34 to rise. Subsequently, the guide rod 34 drives the pull rope 33 to move, pulling the sealing block 31 to move closer to the shunt pipe 22, causing the sealing block 31 to disengage 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 above the ground surface through the breathable net 27, avoiding excessive water vapor in the soil from causing the root rot of forest seedlings and affecting growth. During the upward movement of the lifting ring 35, the slope at its upper end will push the positioning plate 38 into the limit pipe 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 form of the isolation net 25.

[0072] Please refer to again Figures 13 to 18 , the puncture assembly 40 further includes a driving block 42, a lifting frame 43 and a connecting block 44. The driving block 42 is fixedly connected to one end of the puncture needle 41 close to the shunt pipe 22. A through groove penetrating downward is formed in the middle of the sealing block 31, and a lifting frame 43 is slidably connected in the through groove. A connecting block 44 is fixedly connected to the middle of the lifting frame 43. The connecting block 44 penetrates through the sealing block 31 and the fixed pile 26 and is movably inserted into the driving block 42. A through groove adapted to the connecting block 44 is formed in the driving block 42. A magnetic plate is fixedly connected to one side of the driving block 42 close to the shunt pipe 22, and a magnetic plate adapted to it is arranged in the inner cavity of the fixed pile 26, so that the driving block 42 will be adsorbed in the inner cavity of the fixed pile 26 through the magnetic plate under normal conditions, making the driving block 42 unable to slide arbitrarily;

[0073] The puncture assembly 40 further 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 end of the lifting frame 43. A double-layer guide groove 46 is formed at the upper end of the outer wall pipe 24. The upper end of the lifting plate 45 extends into the double-layer guide groove 46, and limiting blocks 47 are slidably connected to both sides of the upper end of the lifting plate 45. The parts of the limiting blocks 47 extending out of the lifting plate 45 are slidably connected in the double-layer guide groove 46. The double-layer guide groove 46 is composed of upper and lower groups of linear guide grooves;

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

[0075] It should be noted that a handle is provided above the limit block 47, and the handle is slidably connected to the lifting plate 45, aiming to drive the movement of the limit block 47 by pulling the handle, so as to facilitate its retraction into the lifting plate 45.

[0076] In this embodiment, in the daily state, the limit block 47 slides in the upper guide groove of the double-layer guide groove 46, and the connecting block 44 is not connected to the driving block 42. After long-term irrigation, when the soil hardens, the limit block 47 is retracted into the lifting plate 45. Subsequently, the lifting plate 45 descends, so that the connecting block 44 is inserted into the driving block 42. Then, the limit block 47 is pushed outwards into the lower guide groove of the double-layer guide groove 46. Subsequently, the restriction on the lifting ring 35 is released. At this time, the first spring 32 quickly rebounds, pushing the sealing block 31 to move, and the sealing block 31 drives the lifting frame 43 and the connecting block 44 to move, and drives 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 to drive the puncture needle 41 to rotate together, so as to disperse the hardened soil around, avoiding affecting the air permeability of the soil. During the dispersion process, the sealing block 31 always moves towards the isolation net 25, avoiding a large amount of dispersed soil entering the outer wall tube 24 and affecting the air permeability.

[0077] The working principle of the present invention is as follows: Insert the outer wall pipe 24 into a suitable irrigation distance from the forest seedlings. Then, pull up the lifting ring 35 to drive the guide rod 34 and the pulling rope 33 to move, pulling the sealing block 31 to move closer to the shunt 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 pipe 24 through the isolation net 25 and discharged above the ground surface through the breathable 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 form of the isolation net 25. When irrigating, add fertilizers or liquid medicines into the liquid storage box 12. When water flows in the main pipe 10, it will push the wind wheel 15 to rotate, and the rotating wind wheel 15 will drive the medicine delivery wheel 14 to rotate together. The liquid medicine or fertilizer in the liquid storage box 12 will be transported into the main pipe 10 through the grooves on the medicine delivery wheel 14, so that it is mixed with the water source in the main pipe 10. The water in the main pipe 10 will flow into the sprinkler head 23 through the branch pipe 21 and the shunt pipe 22, and flow into the soil through the sprinkler head 23 to achieve the irrigation of the forest seedlings. After long-term irrigation, if the soil hardens, retract the limit block 47 into the lifting plate 45. Then, the lifting plate 45 descends, so that the connecting block 44 is inserted into the driving block 42. Immediately afterwards, push the limit block 47 outwards into the lower guide groove of the double-layer guide groove 46. Then, release the restriction on the lifting ring 35. 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 pipe 24 and inserts into the soil. Immediately afterwards, rotate the outer wall pipe 24 to drive the puncture needle 41 to rotate together, stirring the hardened soil around to avoid affecting the air permeability of the soil. During the stirring process, the sealing block 31 always moves towards the direction of the isolation net 25 to prevent a large amount of the stirred soil from entering the outer wall pipe 24 and affecting the air permeability.

[0078] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
