Technical Field
[0001] This utility model relates to the field of drip irrigation technology, specifically a precision drip irrigation device for kudzu planting. Background Technology
[0002] Kudzu is a perennial herbaceous vine whose rhizomes are rich in starch, protein, isoflavones and other nutrients, and have high medicinal and edible value. Its growth requires high soil moisture. In order to ensure water supply during the growth of kudzu, drip irrigation devices are needed to deliver water directly to the vicinity of the kudzu root system at regular intervals and in measured quantities to avoid excessive evaporation and loss of water, while reducing the probability of pests and diseases and improving the yield and quality of kudzu.
[0003] In kudzu cultivation, the commonly used drip irrigation method involves laying drip irrigation pipes on the soil surface for irrigation. However, the drip holes of the drip irrigation pipes tend to be close to the ground, causing soil and impurities to come into contact with the drip holes. This is especially true for moist soil, which is sticky and easily adheres to the drip holes, leading to blockage. Due to the small diameter of the drip holes, cleaning is extremely inconvenient. Current solutions typically involve using numerous poles to lift the drip irrigation pipes and separate them from the soil, but this requires manual setup, increasing labor costs. Furthermore, existing drip irrigation pipes have a simple structure, with fertilizer and water discharged through evenly spaced drip holes. Once laid, it is difficult for users to flexibly and precisely adjust the optimal drip application area according to the actual planting area of the kudzu, which is quite inconvenient. Therefore, to address the above problems, a precision drip irrigation device for kudzu cultivation is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a precision drip irrigation device for kudzu planting, so as to solve the problems that existing drip irrigation pipes are easily blocked when laid on the soil surface, and it is difficult to flexibly and accurately adjust the drip irrigation area after laying.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A precision drip irrigation device for kudzu cultivation includes a drip irrigation pipe, which includes a pipe body. A liquid channel is formed on the inner side of the pipe body. Several equally spaced drip holes are formed on the front side of the liquid channel. Annular grooves are formed on both the left and right sides of each drip hole. Through holes are formed between the annular grooves and the liquid channel. Several receiving channels are formed on the front side of the pipe body, located on the right side of the annular grooves. An elastic membrane ring is formed on the inner side of each annular groove. Both ends of the elastic membrane ring are fixedly connected to the left and right inner walls of the annular grooves. An elastic protective sleeve is fitted onto the outer side of each elastic membrane ring. Several patch drippers connected to the drip holes are fixedly connected to the inner side of the liquid channel. A flow guide is installed at each drip hole. The flow guide includes a flow guide funnel fixed to the inner side of the drip hole. A flow passage sleeve is fixedly connected to the inner side of the flow guide funnel. A nickel-titanium alloy flow guide wire is fixedly connected to the inner side of the flow passage sleeve. The end of the nickel-titanium alloy flow guide wire away from the flow passage sleeve is inserted into the receiving channel.
[0007] Preferably, a middle connector is fixedly connected to the right end of the nickel-titanium alloy guide wire, a positioning pin is fixedly connected to the right side of the middle connector, a protective sleeve is sleeved on the outside of the positioning pin and located in the storage groove, and a pinch strip is fixedly connected to the front side of the middle connector and is located on the left side of the positioning pin.
[0008] Preferably, the flow sleeve consists of a sleeve body and several notches arranged at equal angles, the nickel-titanium alloy flow guide wire is attached to the notches of the flow sleeve, and the flow guide bucket is a tapered sleeve structure that is narrow at the front and wide at the back.
[0009] Preferably, the diameter of the nickel-titanium alloy guide wire is the same as the width of the receiving channel, the diameter of the nickel-titanium alloy guide wire is the same as the depth of the receiving channel, and the nickel-titanium alloy guide wire is in contact with the outer surface of the elastic protective ring on the right side of the drip hole.
[0010] Preferably, the annular grooves are all connected to a pair of through holes arranged symmetrically in the upper and lower positions. The elastic membrane ring and the elastic protective ring are both arranged on the left and right sides of the drip hole. The elastic protective ring is arranged inside the annular groove. The outer curved surface of the elastic protective ring is smoothly transitioned to the outer curved surface of the tube body.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, the drip irrigation pipe, elastic membrane ring, elastic protective ring, and flow guide are designed to support these components. When fertilizer and water are introduced into the drip irrigation pipe, the elastic membrane ring and elastic protective ring expand and protrude, lifting the drip hole area to prevent contact between the drip hole and the ground. The flow guide can precisely direct the fertilizer and water to the desired target location according to the worker's needs. This allows the precision drip irrigation equipment for kudzu planting to be rolled up like a regular drip irrigation pipe under normal conditions, making it easy to lay. During drip irrigation, it automatically rises, reducing the chance of drip hole clogging. Furthermore, the fertilizer and water application area can be flexibly and precisely adjusted as needed, effectively solving the problems of existing drip irrigation pipes being prone to clogging on the soil surface and the difficulty in flexibly and precisely adjusting the drip irrigation area after laying.

[0027] Please see Figure 1-7This utility model provides a technical solution:
[0028] A precision drip irrigation device for kudzu cultivation includes a drip irrigation pipe 1, which includes a pipe body 11. A liquid channel 12 is formed on the inner side of the pipe body 11. Several equally spaced drip holes 13 are formed on the front side of the liquid channel 12. Annular grooves 15 are formed on both the left and right sides of each drip hole 13. Through holes 14 are formed between the annular grooves 15 and the liquid channel 12. Several receiving channels 16 located on the right side of the annular grooves 15 are formed on the front side of the pipe body 11. Elastic membrane rings 3 are formed on the inner side of each annular groove 15. Both ends of the elastic membrane rings 3 are connected to the annular grooves 16. The left and right inner walls of 5 are fixedly connected. The outer side of the elastic membrane ring 3 is fitted with an elastic protective ring 4. The inner side of the liquid channel 12 is fixedly connected with several patch droppers 2 that communicate with the dropper hole 13. The dropper hole 13 is equipped with a flow guide 5. The flow guide 5 includes a flow guide funnel 51 fixed inside the dropper hole 13. The inner side of the flow guide funnel 51 is fixedly connected with a flow passage sleeve 52. The inner side of the flow passage sleeve 52 is fixedly connected with a nickel-titanium alloy flow guide wire 53. The end of the nickel-titanium alloy flow guide wire 53 away from the flow passage sleeve 52 is inserted into the receiving channel 16.
[0029] A central connecting block 54 is fixedly connected to the right end of the nickel-titanium alloy guide wire 53. A positioning pin 56 is fixedly connected to the right side of the central connecting block 54. A protective sleeve 57, located inside the receiving channel 16, is fitted around the outside of the positioning pin 56. This design prevents the positioning pin 56 from damaging the drip irrigation tube 1. A pinch strip 55 is fixedly connected to the front side of the central connecting block 54. The pinch strip 55 is located to the left of the positioning pin 56. This design allows the right end of the nickel-titanium alloy guide wire 53 to be positioned at the desired drip irrigation location. The flow sleeve 52 consists of a sleeve body and several notches arranged at equal angles. The nickel-titanium alloy guide wire 53 is positioned close to the notches of the flow sleeve 52. The flow guide hopper 51 has a tapered sleeve structure that is narrower at the front and wider at the back. This design allows the fertilizer water in the drip hole 13 to be guided onto the nickel-titanium alloy guide wire 53. The diameter of the nickel-titanium alloy guide wire 53 is the same as the width of the receiving channel 16. The diameter of the alloy guide wire 53 is the same as the depth of the receiving channel 16. This design allows the nickel-titanium alloy guide wire 53 to be precisely fitted into the receiving channel 16. The nickel-titanium alloy guide wire 53 is in contact with the outer surface of the elastic protective ring 4 on the right side of the drip hole 13. This design allows the expansion of the elastic protective ring 4 to push the nickel-titanium alloy guide wire 53 out of the receiving channel 16. The annular grooves 15 are all connected to a pair of symmetrically arranged through holes 14. The elastic membrane ring 3 and the elastic protective ring 4 are both located on the left and right sides of the drip hole 13. This design allows the elastic membrane ring 3 and the elastic protective ring 4 to expand and protrude, lifting the drip hole 13. The elastic protective ring 4 is located inside the annular grooves 15. The outer curved surface of the elastic protective ring 4 is smoothly transitioned to the outer curved surface of the tube body 11. This design reduces the protrusion of the normal drip irrigation tube 1 and facilitates the winding of the drip irrigation tube 1.
[0030] Workflow: The operation of the precision drip irrigation equipment for kudzu planting is as follows: Note 1: Drip irrigation pipe 1 needs to be laid in advance and connected to the main water supply pipe of the external irrigation system; Note 2: Nickel-titanium alloy guide wire 53 is a high-performance guide material based on nickel-titanium alloy. It possesses excellent flexibility and corrosion resistance, and its liquid guiding ability is further enhanced by coating its surface with hydrophilic coatings such as polyvinylpyrrolidone and polyethylene oxide. This makes the nickel-titanium alloy guide wire 53 not only excellent in hydrophilicity... Its properties enable it to efficiently guide liquid flow and ensure its corrosion resistance and mechanical stability in complex environments, allowing for the diversion of fertilizer and water. In kudzu cultivation, when the main water supply pipe of the external irrigation system supplies fertilizer and water to the liquid channel 12 of the drip irrigation pipe 1, because the supply speed is much greater than the small-flow drip speed of the drip hole 13 and the patch dripper 2, the fertilizer and water in the liquid channel 12 will quickly fill and pass through the through hole 14 into the annular groove 15. As the amount of fertilizer and water in the annular groove 15 increases, the elastic membrane ring 3 and the elastic protective ring 4 will be... The outward expansion causes the elastic protective ring 4 to protrude from the pipe body 11. Since the elastic protective ring 4 is located on both sides of the drip hole 13, its protruding part can lift the drip hole 13 area of the pipe body 11, preventing the drip hole 13 from contacting the ground, thus significantly reducing the chance of soil and impurities clogging the drip hole 13. Simultaneously, the expansion of the elastic membrane ring 3 and the elastic protective ring 4 will also push out the nickel-titanium alloy guide wire 53 stuck in the receiving channel 16. At this point, the worker only needs to remove the protective sleeve 57 and locate the area requiring precise drip irrigation. Position the device by pinching the strip 55 and inserting the positioning pin 56 into the position. After the fertilizer water drips from the patch dripper 2, it passes through the drip hole 13 and the flow sleeve 52 and attaches to the nickel-titanium alloy guide wire 53. Guided by the guide wire, the fertilizer water is directed to the target drip irrigation position to complete the precise drip irrigation operation. Under normal conditions, the precision drip irrigation equipment for kudzu planting can be rolled up like a normal drip irrigation pipe 1. It is easy to lay out when in use and can be automatically raised during drip irrigation to reduce the chance of the drip hole 13 being blocked. At the same time, the fertilizer water dripping area can be flexibly and precisely adjusted as needed.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
