[0035] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0036] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0037] Example 1:

[0038] like Figures 1 to 10 As shown, this embodiment provides a water-saving sprinkler irrigation device for Platycodon grandiflorus cultivation, which aims to achieve efficient irrigation of the deep root system of Platycodon grandiflorus through a progressive deep irrigation component. The device includes an irrigation network composed of multiple irrigation main pipes, and multiple sprinkler components are fixedly connected to the irrigation main pipes. Each sprinkler component includes a progressive deep irrigation component.

[0039] The structural design of the progressive deep irrigation component is as follows: A connecting pipe 1 is provided at the top. This connecting pipe 1 is made of a flexible hose, possessing good flexibility and facilitating flexible connection with the main irrigation pipe. A top cover 2 is fixedly connected to the bottom end of the connecting pipe 1 by welding or snap-fit. The top cover 2 is a circular cover plate structure, and its outer end is tightly connected to the adjusting cylinder 3 via threads. The adjusting cylinder 3 is a cylindrical hollow structure with a smooth inner wall. A piston 4 is slidably connected inside. The piston 4 is disc-shaped and fits tightly against the inner wall of the adjusting cylinder 3 but can slide freely axially. A telescopic pipe 5 is fixedly connected to the upper surface of the piston 4. The telescopic pipe 5 is a multi-segment sleeve structure that can extend and retract axially. Its outer end is threadedly connected to the inner wall of the adjusting cylinder 3 via a spiral strip, ensuring that the telescopic pipe 5 rotates simultaneously during movement. The bottom end of the telescopic pipe 5 penetrates the lower end of the adjusting cylinder 3, and a self-adjusting component is fixedly connected to the penetrating part.

[0040] The core component of the self-adjusting assembly is the adjusting pipe 6, which is a hollow cylinder with the adjusting capsule 7 fixedly connected inside by bonding or embedding. The adjusting capsule 7 is made of elastic material and has good deformation ability. The inside of the adjusting capsule 7 is filled with a moisture-sensitive material 8, which is selected from hydrogel materials. The moisture-sensitive material 8 can expand in volume when absorbing water and shrink in volume when drying. A plurality of through holes are formed in the side walls of the adjusting pipe 6 and the adjusting capsule 7, which are uniformly distributed, so that the moisture-sensitive material 8 is in direct contact with the external soil environment through the through holes. A gap with a certain width is reserved between the end of the adjusting capsule 7 away from the through holes and the inner wall of the adjusting pipe 6, which serves as a channel for water flow. The bottom end of the adjusting pipe 6 is fixedly connected with the slow-release pipe 9, which is a hollow structure with a tapered structure at the bottom end. The tapered structure has a pointed end facing downward, which is convenient for insertion into the soil. A plurality of slow-release holes are formed in the outer wall of the slow-release pipe 9, and each slow-release hole is filled with a slow-release strip 13 made of plant fiber, which has good water permeability and biodegradability. In addition, a boss is arranged at the outer end of the slow-release pipe 9 close to the tapered structure. The boss is an annular structure with an outer diameter larger than the main body outer diameter of the slow-release pipe 9, forming a protection area.

[0041] During installation, the connecting pipe 1 of the progressive deep irrigation assembly is connected with the irrigation main pipe, and the remaining part is buried in the soil. The tapered end of the slow-release pipe 9 is inserted into the soil first, and the boss follows, ensuring smooth insertion.

[0042] Working process

[0043] In use, high-pressure water flow enters the connecting pipe 1 through the irrigation main pipe. Since the connecting pipe 1 is a flexible hose, the water flow can be smoothly transmitted to the space between the top cover 2 and the piston 4, forming a temporary water storage area. The water flow is divided into two parts from here: one is through the telescopic pipe 5 into the adjusting pipe 6, and the other is to apply pressure to the piston 4.

[0044] The water flow entering the adjusting pipe 6 flows downward through the gap between the adjusting capsule 7 and the inner wall of the adjusting pipe 6, and finally reaches the slow-release pipe 9. The water flow in the slow-release pipe 9 slowly penetrates into the soil through the slow-release holes. The slow-release strip 13 plays a buffering role in this process, allowing the water flow to be released uniformly and avoiding excessive irrigation at one time.

[0045] The self-adjusting assembly automatically adjusts the water flow rate according to the soil humidity. When the soil is dry, the moisture in the moisture-sensing material 8 penetrates into the soil through the through holes on the adjusting tube 6 and the adjusting capsule 7, is absorbed by the soil, and causes the moisture-sensing material 8 to shrink in volume. At this time, the adjusting capsule 7 shrinks under its own elasticity, the gap between the adjusting capsule 7 and the inner wall of the adjusting tube 6 widens, and the water flow rate increases, thereby providing more water for the dry soil. As the soil humidity gradually increases, the water in the soil penetrates into the moisture-sensing material 8 through the through holes in the opposite direction, and the moisture-sensing material 8 expands in volume after absorbing water, thereby expanding the adjusting capsule 7 and narrowing the gap between the adjusting capsule 7 and the adjusting tube 6, and the water flow rate decreases. When the soil humidity reaches the saturation state, the adjusting capsule 7 is fully expanded and blocks the gap, and the water flow is cut off until the soil humidity decreases and the moisture-sensing material 8 shrinks again to enter the next cycle.

[0046] As the jithomia grows, its root system gradually penetrates into the soil. The external water supply system inputs high-pressure water between the top cover 2 and the piston 4, the water pressure drives the piston 4 to move downward, and the telescopic tube 5 moves downward along the inner wall of the adjusting cylinder 3. Since the telescopic tube 5 is connected with the adjusting cylinder 3 through threads, the telescopic tube 5 rotates simultaneously during the downward movement, thereby driving the adjusting tube 6 and the slow-release tube 9 to be inserted into deeper soil in a spiral manner. The self-adjusting assembly and the slow-release tube 9 are thereby deepened, thereby providing water for deep root systems and achieving dynamic irrigation.

[0047] Through the thread cooperation between the telescopic tube 5 and the adjusting cylinder 3 and the pushing action of the piston 4, the slow-release tube 9 can grow into the soil along with the jithomia root system, thereby ensuring that the deep root system obtains sufficient water and improving the pertinence of irrigation.

[0048] The self-adjusting assembly composed of the moisture-sensing material 8 and the adjusting capsule 7 can automatically adjust the water flow rate according to the soil humidity, increase the water supply when the soil is dry, and reduce or stop the water supply when the humidity is high, thereby effectively reducing the waste of water resources.

[0049] The slow-release strip 13 on the slow-release tube 9 slowly releases the water flow, avoids rapid loss of the water flow, improves the water utilization rate, and simultaneously, the slow-release strip 13 of the plant fiber material can be gradually degraded without polluting the soil.

[0050] The boss design of the slow-release tube 9 protects the slow-release strip 13 from being extruded by the soil or scratched by stones when being inserted into the soil, thereby ensuring the long-term functionality of the slow-release hole.

[0051] The connecting tube 1 adopts a flexible hose, which is convenient to connect with the irrigation main pipe, is suitable for different terrains, and enhances the practicability of the device.

[0052] The embodiment realizes dynamic and efficient irrigation for the deep root system of the jithomia through the precise design of the progressive deep irrigation assembly, simultaneously meets the water-saving and environmental protection requirements, and is suitable for the scene mainly using deep irrigation in jithomia cultivation.

[0053] Embodiment 2:

[0054] As Figures 1 to 10 shown, this embodiment is further expanded on the basis of embodiment 1 into a comprehensive water-saving type of combined layered irrigation and surface sprinkling device for cultivation of kudzu vine, which comprises an irrigation network composed of multiple irrigation main pipes, the irrigation network being connected in communication with an external high-pressure water supply system, the irrigation main pipes being fixedly connected with multiple sprinkling assemblies, each sprinkling assembly not only comprising the progressive deep irrigation assembly described in embodiment 1, but also newly added at least one layered irrigation assembly to meet the needs of multi-level root system and surface irrigation of kudzu vine.

[0055] The structure of the progressive deep irrigation assembly is consistent with that of embodiment 1, comprising a connecting pipe 1, a top cover 2, an adjusting cylinder 3, a piston 4, an extension pipe 5, a self-adjusting assembly (including an adjusting pipe 6, an adjusting capsule 7, and a moisture-sensing material 8), and a slow-release pipe 9, the function of which is focused on dynamic irrigation of deep root system, while the layered irrigation assembly is newly added as a structure, the core component of which is a layered irrigation pipe 10, which is a hollow cylindrical pipe fixedly connected to the outer end of the adjusting cylinder 3 by welding or bolt, the top cover 2 and the piston 4 forming a closed pressurizing chamber therebetween, the layered irrigation pipe 10 being connected in communication with the pressurizing chamber through a small pipe to ensure that water flow can be diverted from the pressurizing chamber to the layered irrigation pipe 10.

[0056] The top end of the layered irrigation pipe 10 is threadedly connected with a sprinkler 11, which is of a conical structure with its larger-diameter end close to the layered irrigation pipe 10, the top thereof being flat and provided with multiple spray holes distributed in a radial pattern to ensure that water flow is uniformly sprayed in mist form to the ground surface, the sprinkler 11 being detachable and replaceable with a plug if surface sprinkling is not needed, the end of the layered irrigation pipe 10 away from the adjusting cylinder 3 being fixedly connected with multiple self-adjusting assemblies, which are identical in structure to the self-adjusting assembly in embodiment 1 (including the adjusting pipe 6, the adjusting capsule 7, and the moisture-sensing material 8) and connected in communication with the interior of the layered irrigation pipe 10 through pipes, the multiple self-adjusting assemblies being arrayed in sequence along the axial direction of the layered irrigation pipe 10, each self-adjusting assembly corresponding to a different depth of soil layer.

[0057] For ease of installation and protection, the outer end of the adjusting cylinder 3 is further fixedly connected with a mounting handle 12, which is of a strip structure with its top end bent away from the adjusting cylinder 3 to form an arc-shaped handle for easy gripping, and its bottom end extending downward to the underside of the lowermost self-adjusting assembly of the layered irrigation pipe 10 to form a protective barrier, during installation, the progressive deep irrigation assembly (except the connecting pipe 1) and part of the layered irrigation assembly being inserted into the soil through the mounting handle 12, and the sprinkler 11 being located above the soil.

[0058] Working process

[0059] In use, the user holds the installation handle 12, inserts the top cover 2, the adjusting cylinder 3, the telescopic pipe 5, the adjusting pipe 6 and the slow-release pipe 9 of the progressive deep irrigation assembly, and the layered irrigation pipe 10 and the self-adjusting assembly thereon of the layered irrigation assembly into the soil, covers the bottom end of the installation handle 12 outside the lowermost self-adjusting assembly of the layered irrigation pipe 10 to prevent the soil or stones from pressing or scratching it, after installation, connects the connecting pipe 1 with the irrigation main pipe, and the device can be put into use, and when disassembling, pulls the installation handle 12 to lift the device upward, and then disconnects the connecting pipe 1 from the irrigation main pipe.

[0060] When irrigation starts, the external high-pressure water supply system delivers high-pressure water flow to the connecting pipe 1 through the irrigation main pipe, the water flow enters the booster chamber between the top cover 2 and the piston 4, and the water flow in the booster chamber is divided into two paths: one path enters the adjusting pipe 6 through the telescopic pipe 5, and finally slowly penetrates into the deep soil through the slow-release pipe 9 (the process is the same as that of example 1); the other path enters the layered irrigation pipe 10 through the pipeline, and the water flow is divided in the layered irrigation pipe 10, part of the water flow penetrates into soil layers at different depths through multiple self-adjusting assemblies, and the other part flows upward to the spray head 11 and is sprayed in mist form to the ground surface through the spray holes.

[0061] The self-adjusting assembly on the layered irrigation pipe 10 automatically adjusts the water flow according to the surrounding soil humidity, when the soil is dry, the moisture-sensing material 8 loses water and shrinks, the adjusting capsule 7 contracts, the gap with the inner wall of the adjusting pipe 6 increases, the water flow increases, and more water is provided for the roots at the corresponding depth, as the soil humidity rises, the moisture-sensing material 8 absorbs water and swells, the adjusting capsule 7 is expanded, the gap becomes smaller, the water flow decreases, and when the soil is saturated, the gap is blocked, the water flow stops, and the next cycle after the humidity decreases starts, multiple self-adjusting assemblies are distributed axially along the layered irrigation pipe 10 and correspond to different depths of the luffa root system respectively, to ensure multi-level irrigation.

[0062] As the luffa grows, the deep root system gradually expands, the high-pressure water flow acts on the booster chamber, pushes the piston 4 and the telescopic pipe 5 to move downward, the telescopic pipe 5 rotates through the thread cooperation with the adjusting cylinder 3, and the slow-release pipe 9 and the self-adjusting assembly are deeply inserted into the soil to supply water to the newly grown deep root system, at the same time, the spray head 11 continuously sprays irrigation to the ground surface to meet the needs of the ground root system and the plant, if there is no need for surface irrigation, the spray head 11 can be removed and a plug is installed, and only the internal soil penetration irrigation is left.

[0063] Multiple self-adjusting assemblies on the layered irrigation pipe 10 are distributed in an axial array and correspond to roots of the luffa at different depths respectively, to ensure that the shallow, middle and deep root systems all obtain appropriate water, and the overall irrigation is improved.

[0064] The spray head 11 realizes uniform surface spraying through the conical structure and multiple spray holes, and cooperates with the deep penetration of the progressive deep irrigation assembly to form a comprehensive irrigation system from the surface to the deep layer, to meet the needs of the luffa in the whole growth cycle.

[0065] In use, the progressive deep irrigation assembly is inserted into the soil by installing the handle 12 to the whole and part of the layered irrigation assembly except the connecting pipe 1, in the process of insertion, the handle 12 protects the self-adjusting assembly on the layered irrigation pipe 10 from being damaged by the soil or stones in the soil; when it is necessary to remove the device, the device can be removed by disconnecting the connecting pipe 1 from the irrigation main pipe after pulling the handle 12 upward;

[0066] In use, the high-pressure water flow enters between the top cover 2 and the piston 4 through the connecting pipe 1, part of the water flow enters the regulating pipe 6 through the telescopic pipe 5, then enters the slow-release pipe 9 through the regulating pipe 6, and finally slowly penetrates into the soil from the slow-release pipe 9, and the other part enters the layered irrigation pipe 10 and slowly penetrates into the soil through the multiple self-adjusting assemblies;

[0067] The self-adjusting assembly automatically adjusts the penetration speed of the water flow according to the moisture content of the surrounding soil in real time;

[0068] When the soil is dry, the moisture of the moisture-sensing material 8 on the self-adjusting assembly penetrates into the soil and is absorbed by the soil, which causes the volume of the moisture-sensing material 8 to decrease, at this time, the regulating capsule 7 shrinks under the action of elasticity, which causes the distance between the regulating capsule 7 and the inner wall of the regulating pipe 6 to increase, and thus the flow of water flowing through this self-adjusting assembly increases, so that the soil at this position has more water supply;

[0069] As the water supply gradually increases, the soil moisture gradually increases, at this time, the moisture in the soil penetrates into the moisture-sensing material 8 through the through hole on the regulating capsule 7 of the regulating pipe 6 and is absorbed by the moisture-sensing material 8, which causes the volume of the moisture-sensing material 8 to increase, and the moisture-sensing material 8 in turn causes the regulating capsule 7 to expand, thereby reducing the gap between the regulating capsule 7 and the regulating pipe 6, and reducing the flow of water flowing between the regulating pipe 6 and the regulating capsule 7, when the soil moisture reaches a certain humidity, the gap between the regulating pipe 6 and the regulating capsule 7 is blocked by the regulating capsule 7, thereby cutting off the water flow, until the soil humidity decreases to a certain extent, causing the moisture-sensing material 8 to lose water and decrease in volume, and then entering the next cycle;

[0070] The multiple self-adjusting assemblies on the layered irrigation pipe 10 correspond to the root systems at different depths of the orange jujube respectively;

[0071] With the growth of the jiegeng, its root depth increases, at this time, only by embedding the self-adjusting assembly for jiegeng irrigation, can not meet the new growth of deep roots, at this time, through the external water supply system, the high pressure water is supplied between the top cover 2 and the piston 4, under the action of water pressure, the piston 4, the telescopic pipe 5, the adjusting pipe 6, the slow-release pipe 9 are pushed to move downward, at the same time, the telescopic pipe 5 is rotated by cooperating with the thread of the adjusting cylinder 3, so that the self-adjusting assembly connected with the telescopic pipe 5 can better penetrate into the soil, and then the deep roots of jiegeng are irrigated through the self-adjusting assembly;

[0072] During the whole use process, the spray head 11 sprays the ground, thereby realizing irrigation of the ground and multi-layer deep roots of jiegeng, and realizing irrigation of deeper roots by following the growth of jiegeng through the telescopic pipe 5, and realizing dynamic adjustment.

[0073] The spray head 11 can be selected and installed as needed, and can be replaced by a plug when not needed, and the water is infiltrated and irrigated by automatically sensing the humidity in the soil, reducing the evaporation of surface water and reducing the use of water resources.

[0074] The self-adjusting assembly on the layered irrigation pipe 10 and the progressive deep irrigation assembly are automatically adjusted by the wet material 8, and the water flow is increased when the soil is dry, and is reduced or stopped when the soil is wet, thereby significantly reducing water waste.

[0075] The installation handle 12 is designed reasonably, which is convenient for holding and inserting into the soil, and protects the self-adjusting assembly on the layered irrigation pipe 10 from being damaged, and improves the durability of the device.

[0076] The spray head 11 can be replaced by a plug as needed to avoid unnecessary water evaporation, and the combination of the external high-pressure water supply system and the booster chamber ensures efficient distribution of water flow to each layer of soil.

[0077] The cooperation of the telescopic pipe 5 and the piston 4 makes the slow-release pipe 9 penetrate into the soil with the growth of the roots, dynamically adjusts the irrigation depth, and enhances the adaptability to the growth changes of jiegeng.

[0078] The embodiment realizes the comprehensive function of surface sprinkling and multi-layer root irrigation on the basis of the deep irrigation of embodiment 1 through the introduction of the layered irrigation pipe 10 and the spray head 11, and takes into account water saving, intelligent adjustment and installation convenience, and is suitable for scenes with high multi-layer irrigation demand in jiegeng cultivation.
