Description

Technical Field

[0001] This utility model relates to the technical field of drip irrigation devices, specifically to a drip irrigation device for high-yield wheat cultivation. Background Technology

[0002] To ensure normal crop growth and achieve high and stable yields, crops must be supplied with sufficient water. Under natural conditions, insufficient or uneven rainfall often fails to meet the crop's water requirements. Therefore, artificial irrigation is necessary to supplement the lack of natural rainfall. Drip irrigation uses plastic pipes to deliver water to the crop roots through orifices or drippers on capillary tubes with a diameter of about 10mm. It is currently the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can be combined with fertilization to increase fertilizer efficiency by more than double.

[0003] Common drip irrigation systems require the laying of a large number of drip irrigation pipes. However, existing drip irrigation systems for high-yield wheat cultivation generally use drip irrigation pipes of fixed length, which cannot be adjusted to suit wheat of different lengths in the field. In addition, the drip irrigation pipes in existing drip irrigation systems cannot filter the drip irrigation solution, which can easily lead to blockage from the inside, resulting in insufficient irrigation for some wheat and affecting wheat yield.

[0035] See Figure 1-4 As shown, a drip irrigation device for high-yield wheat cultivation includes an external pipe 1 and a main pipe 2. One end of the main pipe 2 is provided with a filter section 3, which is also located inside the external pipe 1. The outer side of the main pipe 2 is fixedly connected with pipe assemblies 4 and an external filter pipe 5 distributed at equal intervals. The external filter pipe 5 and the main pipe 2 are connected by a delivery branch pipe 16. The surface of the filter section 3 is covered with a filter screen 6. An expansion section 8 and a guide section 9 are provided at the joint end of the external pipe 1 and the main pipe 2. The surface of the filter section 3 is provided with a through hole 7. The pipe assembly 4 includes a sleeve 10 fixedly connected to the main pipe 2, and an inner pipe 11 and an external drip irrigation pipe 12 that are movably fitted. The outer end of the inner pipe 11 is fixedly connected with a guide frame 13. A sealing ring 14 is fixedly connected at the joint end of the external drip irrigation pipe 12 and the inner pipe 11.

An expansion cavity 17 is provided at equal intervals at the bottom end of the main pipe 2 corresponding to the position of the pipe assembly 4.

[0036] In this embodiment, the external pipe 1 and the main pipe 2 are threaded together at one end. The external pipe 1 is tapered between its inner and outer ends. The guide section 9 is located at both the inner and outer ends of the external pipe 1. The extension section 8 is annularly convex and located on one side of the guide section 9 and facing the main pipe 2. The external pipe 1 is threaded on its inner side. The main pipe 2 located inside the external pipe 1 is closed. The filter screen 6 is a tapered filter screen fitted onto the filter section 3. The through hole 7 is a strip-shaped opening along the surface of the filter section 3 and is located below the extension section 8. The external pipe 1 facilitates the threaded connection between the overall device and the external liquid supply equipment. The guide section 9 concentrates the input external liquid. The extension section 8 ensures the flow of the liquid through the through hole 7. The filter screen 6 filters the input external liquid. The through hole 7 facilitates the entry of the filtered external liquid into the main pipe 2.

[0037] When the external liquid medicine is input between the external pipe 1 and the main pipe 2, it first passes through the filter screen 6 to intercept impurity particles. Then, the liquid medicine is guided and concentrated by the guide section 9 into the expansion section 8, and enters the main pipe 2 through the through hole 7 for subsequent spraying.

[0038] The outer filter pipe 5 and the main pipe 2 are connected laterally, and the outer filter pipe 5 has an arc-shaped filter screen inside. The outer end of the outer filter pipe 5 is provided with a detachable threaded cap. The conveying branch pipe 16 is set in an arc shape. A sealing layer 15 is fixedly sleeved between the outer filter pipe 5 and the inner pipe 11. The outer filter pipe 5 achieves the effect of secondary filtration of the external medicine liquid conveyed from the main pipe 2. The sealing layer 15 achieves the effect of sealing between the inner pipe 11 and the outer filter pipe 5. The conveying branch pipe 16 achieves the effect of conveying the medicine liquid in the main pipe 2 to the outer filter pipe 5.

[0039] After the liquid medicine enters the main pipe 2, it is transported to the external filter pipe 5 through the arc-shaped delivery branch pipe 16 for secondary filtration and interception.

[0040] The sleeve 10 is horizontally embedded in the main pipe 2. The inner pipe 11 is horizontally positioned as a whole, with one end of it embedded in the outer drip irrigation pipe 12 being open. The guide frame 13 is a ring frame that is slidably embedded in the outer drip irrigation pipe 12. Waterproof rare earth magnets are provided on the edge of the guide frame 13. The sealing ring 14 is located inside the outer drip irrigation pipe 12. The outer drip irrigation pipe 12 is horizontally positioned as a whole, and multiple sets of drip irrigation holes are opened on its surface. Waterproof rare earth magnets are provided between each set of drip irrigation holes corresponding to the guide frame 13. The outer end of the outer drip irrigation pipe 12 is closed. The sleeve 10 achieves the effect of connecting and fixing the inner pipe 11. The inner pipe 11 achieves the effect of delivering external medicine liquid. The outer drip irrigation pipe 12 achieves the effect of discharging medicine liquid for drip irrigation. The guide frame 13 ensures the stability of the inner pipe 11 sliding in the outer drip irrigation pipe 12. At the same time, the telescopic connection between the inner pipe 11 and the outer drip irrigation pipe 12 facilitates the length adjustment according to drip irrigation needs. The sealing ring 14 ensures the sealing effect between the outer drip irrigation pipe 12 and the inner pipe 11.

[0041] The filtered medicine is transported from the outer filter tube 5 to the inner tube 11. The user adjusts the length of the outer drip irrigation tube 12 and the inner tube 11 according to the drip irrigation area. Then the medicine flows from the outer end of the inner tube 11 into the outer drip irrigation tube 12 and completes the drip irrigation through the drip irrigation holes on the surface of the outer drip irrigation tube 12. When adjusting the length of the outer drip irrigation tube 12 and the inner tube 11, the guide frame 13 and each group of drip irrigation holes on the surface of the outer drip irrigation tube 12 are equipped with magnetic attraction layers, which can ensure the limiting and fixing of the outer drip irrigation tube 12 and the inner tube 11 under different lengths. At the same time, during the drip irrigation process, the guide frame 13 is set as a ring frame, which only provides guidance and will not block or obstruct the drip irrigation holes on both sides.

[0042] The expansion cavity 17 is a hemispherical convex shape, which increases the capacity of the main pipe 2 to external liquid.

[0043] In this embodiment, an integrated flow sensor can be installed in the main pipe 2 or the delivery branch pipe 16 to monitor the amount of medicine delivered in real time and transmit the data to the terminal via a wireless module.

[0044] Pressure regulating valve: Based on the length difference of the drip irrigation area, a pressure regulating valve is added at the inlet of the main pipe 2 to ensure the uniformity of drip irrigation at the far end and near end.

[0045] In this embodiment, the main pipe 2 and the inner pipe 11 are made of corrosion-resistant materials such as UPVC or inner wall coating to prevent liquids such as fertilizers and pesticides from corroding the pipes.

[0046] The surface of the external drip irrigation pipe 12 is coated with UV-resistant material to prevent aging caused by long-term exposure to sunlight.

[0047] The drip holes on the surface of the external drip irrigation pipe 12 are made of elastic silicone material, which automatically closes when there is no pressure to prevent soil backflow or evaporation.

[0048] In this embodiment, a transparent observation window can be provided at the external filter tube 5 or the filter section 3 to facilitate intuitive judgment of the blockage situation;

[0049] A drain outlet is provided at the lowest point of the bottom of the expansion cavity 17 to facilitate the discharge of sediment.

[0050] In this embodiment, a one-way valve can be installed at the inlet of the delivery branch pipe 16 to prevent the liquid medicine from flowing back and contaminating the main pipeline;

[0051] The extension and retraction of the outer drip irrigation pipe 12 and the inner pipe 11 can be set to be electrically driven, such as a micro stepper motor, and the length can be adjusted by remote control to adapt to the needs of different planting densities.

[0052] The above supplements can be selectively integrated according to actual application scenarios to improve the reliability, intelligence, and environmental adaptability of the device.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
