Description

Technical Field

[0001] This utility model relates to the field of drip irrigation, and in particular to a pulse drip irrigation device with adjustable flow rate. Background Technology

[0002] Currently, traditional drip irrigation systems generally use a continuous water output method, which has problems such as low water resource utilization and easy clogging. Especially on slopes or over long distances, insufficient end-point pressure leads to a significant decrease in drip irrigation effect. Existing pulse drip irrigation technology mostly relies on external power or complex solenoid valve control, which not only increases energy consumption and maintenance costs, but also makes it difficult to adapt to field operation environments.

[0003] To address the aforementioned issues, this patent proposes a drip irrigation device that requires no external energy, has a compact structure, and can autonomously generate high-pressure pulses. While achieving water-saving irrigation, it also possesses anti-clogging characteristics to meet the demands of modern agriculture for efficient and precise irrigation. Utility Model Content

[0004] The main purpose of this invention is to propose an adjustable flow pulse drip irrigation device, which aims to solve the problems of low water resource utilization and easy clogging of traditional drip irrigation devices.

[0005] To address the aforementioned problems, this utility model proposes an adjustable flow pulse drip irrigation device, comprising a transmission pipe, impeller assemblies disposed on both the front and rear sides of the transmission pipe, connecting pipe heads connected to both the front and rear ends of the transmission pipe, a drip irrigation pipe connected to the center of the lower end of the transmission pipe, a pulse jet assembly disposed inside the drip irrigation pipe, and the pulse jet assembly connected to the lower side between the two impeller assemblies, and adjusting rings rotatably connected to the front and rear sides of the transmission pipe through positioning ring grooves, locking bolts threaded into the upper ends of the two adjusting rings, and positioning rods connected to the lower ends of the two adjusting rings.

[0006] Preferably, the impeller assembly includes a limiting frame, an impeller shaft, and a spiral blade. The impeller shaft is rotatably connected to the interior of both the front and rear sides of the transmission tube, and the limiting frame is rotatably connected to the exterior of both the front and rear ends of the two impeller shafts.

[0007] Preferably, all four limiting frames are connected to the inner wall of the transmission tube, and both impeller shafts are connected to the outside of the two impeller shafts with helical blades in opposite directions. Both impeller shafts are connected to a driving helical gear at opposite ends.

[0008] Preferably, the pulse jet assembly includes a sealing tube, a pressurizing tube, and a sealing slider. A sealing plate is connected to the upper side of the inner wall of the drip irrigation tube, and multiple through holes are opened on the outer side of the center of the sealing plate. A sealing tube is connected to the outer side of the lower end of the sealing plate and communicates with the inside of the sealing tube through the through holes. A gap is left between the sealing tube and the inner wall of the drip irrigation tube.

[0009] Preferably, the outer wall of the sealing tube cylinder is provided with multiple spray windows, the lower end of the sealing tube is rotatably connected to a pressure boosting tube with an upward opening, and the upper end of the pressure boosting tube is connected to a linkage shaft through a connecting frame at the center, and the upper end of the linkage shaft passes through the center of the sealing plate and extends into the transmission tube.

[0012] 1. This utility model achieves series installation of the device through the connecting pipe ends of the transmission pipe. With the help of the rotatable adjustment ring and positioning rod, the direction of the drip irrigation pipe can be adjusted and it can be accurately positioned at the plant roots. After the locking bolt is fixed, it ensures the stability of the drip irrigation position and adapts to the needs of different planting layouts.

[0013] 2. The impeller assembly of this utility model adopts a reverse spiral blade and a driving helical gear. The water flow drives the double impellers to rotate in opposite directions.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To achieve the above-mentioned utility model objectives, such as Figures 1-6As shown, this utility model provides an adjustable flow pulse drip irrigation device, including a transmission pipe 1. Impeller assemblies are installed inside both the front and rear sides of the transmission pipe 1. Connecting pipe heads 2 are connected to both the front and rear ends of the transmission pipe 1. A drip irrigation pipe 3 is connected to the center of the lower end of the transmission pipe 1. A pulse jet assembly is installed inside the drip irrigation pipe 3, and the pulse jet assembly is connected to the lower side between the two impeller assemblies. Adjusting rings 4 are rotatably connected to the front and rear sides of the transmission pipe 1 through positioning ring grooves. Locking bolts 5 are threadedly connected to the upper ends of the two adjusting rings 4. Positioning rods 6 are connected to the lower ends of the two adjusting rings 4. During the operation of the pulse drip irrigation device, multiple transmission pipes 1 are provided and connected in series in the middle of the water pipe through the connecting pipe heads 2 at both ends. The transmission pipe 1 can be inserted into the roots of the plants that need drip irrigation through the two positioning rods 6 on both sides of the lower end. The orientation of the drip irrigation pipe 3 is adjusted by rotating inside the two adjusting rings 4 through the positioning ring grooves, so that the drip irrigation pipe 3 is aligned with the drip irrigation position, and the position is fixed by the locking bolts 5.

[0021] At this time, the water in the water pipe enters the pulse jet assembly inside the drip irrigation pipe 3 through the transmission pipe 1, and drives the impeller assembly to rotate. The impeller assembly then drives the pulse jet assembly to rotate, so that the water entering the pulse jet assembly can be intermittently sprayed into the drip irrigation pipe 3, and the water pressure inside the drip irrigation pipe 3 is increased. The water intermittently sprayed into the drip irrigation pipe 3 drips out from the lower end of the drip irrigation pipe 3, thereby realizing pulse drip irrigation for plants. The flow rate of drip irrigation can be regulated by controlling the water pressure inside the water pipe.

[0022] Preferably, the impeller assembly includes a limiting frame 7, an impeller shaft 8, and a spiral blade 9. The impeller shaft 8 is rotatably connected to the interior of both the front and rear sides of the transmission pipe 1. The limiting frames 7 are rotatably connected to the exterior of both ends of the two impeller shafts 8. The four limiting frames 7 are all connected to the inner wall of the transmission pipe 1. The spiral blades 9 are connected to the exterior of both impeller shafts 8, and the spiral directions of the two spiral blades 9 are opposite. The opposite ends of the two impeller shafts 8 are connected to a driving helical gear 10. When water flows through the interior of the transmission pipe 1, the water flow can drive the two spiral blades 9 to rotate around the two impeller shafts 8, and drive the two driving helical gears 10 to rotate. The rotation position of the two impeller shafts 8 is limited by the four limiting frames 7. Since the two spiral blades 9 are arranged in opposite spirals, the two spiral blades 9 rotate in opposite directions inside the transmission pipe 1, and drive the two driving helical gears 10 to rotate in opposite directions.

[0023] Preferably, the pulse jet assembly includes a sealing tube 12, a booster tube 14, and a sealing slider 19. A sealing plate 11 is connected to the upper side of the inner wall of the drip irrigation tube 3, and multiple through holes are opened on the outer side of the center of the sealing plate 11. The sealing tube 12 is connected to the outer side of the lower end of the sealing plate 11 and communicates with the inside of the sealing tube 12 through the through holes. A gap is left between the sealing tube 12 and the inner wall of the drip irrigation tube 3. Multiple jet windows 13 are opened on the outer cylindrical wall of the sealing tube 12. A booster tube 14 with an upward opening is rotatably connected to the lower end of the sealing tube 12. 4. A linkage shaft 15 is connected to the center of the upper end of the booster pipe 14 via a connecting bracket. The upper end of the linkage shaft 15 passes through the center of the sealing plate 11 and extends into the transmission pipe 1. The linkage shaft 15 is rotatably connected to the inside of the sealing plate 11 and is connected to the sealing plate 11 via a limiting ring. A driven helical gear 16 is connected to the upper end of the linkage shaft 15. The driven helical gear 16 is located at the lower end between the two driving helical gears 10 and meshes with the two driving helical gears 10. An injection port 17 is opened on the outer cylindrical wall of the booster pipe 14. The upper and lower inner walls of the injection nozzle 17 are flush with the upper and lower inner walls of the multiple injection windows 13. During the operation of the impeller assembly driving the pulse assembly, because the two driving helical gears 10 mesh with the upper left and right sides of the driven helical gear 16 and rotate in opposite directions, the impeller assembly simultaneously drives the driven helical gear 16 to rotate via the two driving helical gears 10, providing a strong driving force. The driven helical gear 16 drives the booster pipe 14 to rotate inside the sealing pipe 12 via the linkage shaft 15. At this time, the water inside the transmission pipe 1 passes through the sealing plate 1... A through hole is opened on the outer side of the center to enter the interior of the booster pipe 14. When the booster pipe 14 rotates, it drives the spray nozzle 17 to rotate between multiple spray windows 13 and connects with multiple spray windows 13 in sequence. This allows the booster pipe 14 to intermittently spray water into the drip irrigation pipe 3 through the sequential connection between the spray nozzle 17 and multiple spray windows 13. The water intermittently sprayed into the drip irrigation pipe 3 accumulates on the inner wall of the drip irrigation pipe 3 and drips intermittently from the lower end of the drip irrigation pipe 3, thereby realizing pulse drip irrigation for plants.

[0024] Preferably, a limiting ring 18 is connected to the lower inner wall of the booster pipe 14. A hollow sealing slider 19 is provided at the lower end of the limiting ring 18, and the sealing slider 19 is slidably connected inside the lower end of the booster pipe 14. A pressure spring 20 is provided at the lower end of the sealing slider 19, and the pressure spring 20 is located inside the booster pipe 14. An exhaust hole 21 is opened at the center of the lower end of the booster pipe 14. When the spray nozzle 17 rotates between the two spray windows 13, the spray windows 13 and the spray nozzle 17 are not connected, so the booster pipe 14 is not connected to the drip irrigation pipe 3. The water inside the booster pipe 14 cannot be sprayed out, resulting in an increase in internal water pressure, which squeezes the sealing slider 19, causing the sealing slider 19 to slide downward inside the lower end of the booster pipe 14 and compressing the pressure spring 20. Furthermore, the air in the pressurizing pipe 14 located at the lower end of the blocking slider 19 can be discharged through the exhaust hole 21, ensuring that the blocking slider 19 can slide down smoothly and store the increased water pressure inside the pressurizing spring 20. When the spray nozzle 17 rotates to the spray window 13 position, the spray window 13 is connected to the spray nozzle 17, and the pressurizing pipe 14 is connected to the drip irrigation pipe 3 through the spray window 13 and the spray nozzle 17, so that the high-pressure water inside the pressurizing pipe 14 can be sprayed into the drip irrigation pipe 3 through the spray window 13 and the spray nozzle 17. At the same time, the pressurizing spring 20 can release the stored water pressure by pushing the blocking slider 19 upward, so that the pressurizing pipe 14 can continuously spray high-pressure water, which can not only achieve rapid drip irrigation, but also prevent impurities in the water from clogging the spray nozzle 17, ensuring the normal operation of drip irrigation.

[0025] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
