Description

Technical Field

[0001] This utility model relates to the field of drip irrigation pipe technology, and in particular to a dual-mode water-saving device for farmland drip irrigation. Background Technology

[0002] Drip irrigation pipes are the core irrigation equipment of drip irrigation systems. They deliver water and nutrients precisely to the soil around the roots of crops through low-pressure pipes and sprinklers on the capillary tubes. They are mainly used in field crops, orchards, greenhouses, and greening projects.

[0003] When cultivating vegetation crops, drip irrigation is used to better irrigate the roots. When the sun is strong, sprinkler irrigation is needed to wet the surface of the vegetation crops to avoid damaging the branches.

[0004] However, switching between drip irrigation and sprinkler irrigation requires changing the pipeline, which necessitates manual connection for disassembly and installation, making irrigation pipe replacement difficult. Therefore, this invention proposes a dual-mode water-saving device for farmland drip irrigation. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that switching between drip irrigation and sprinkler irrigation requires manual connection for disassembly and installation, making irrigation pipe replacement difficult. This invention proposes a dual-mode water-saving device for farmland drip irrigation.

[0006] The technical solution of this utility model is as follows: A dual-mode water-saving device for farmland drip irrigation includes an irrigation pipe, on the outside of which drip irrigation holes are provided. Multiple sets of drip irrigation holes are arranged in a circumferential array. A branch pipe is fixedly connected inside the irrigation pipe. An inlet is provided on the side of the branch pipe near the inside of the irrigation pipe. The inside of the branch pipe, away from the inlet, is connected to the drip irrigation holes. A positioning plate is fixedly connected inside the irrigation pipe. Sprinkler holes are provided on the outside of the irrigation pipe, away from the drip irrigation holes.

[0007] The positioning plate has a water inlet hole inside, and a sealing plate is abutting against the positioning plate near the diversion pipe. A flow hole is opened inside the sealing plate. A sliding rod is fixedly connected to the sealing plate near the positioning plate. The sliding rod is slidably connected inside the positioning plate. The water inlet hole and the flow hole are arranged in a cross pattern.

[0008] Optionally, a pressing plate is fixedly connected to the end of the sliding rod away from the sealing plate, a spring is fixedly connected to the side of the pressing plate near the sliding rod, the end of the spring away from the pressing plate is fixedly connected to the side of the positioning plate away from the sealing plate, the spring is disposed outside the sliding rod, and a closing assembly is disposed at the top of the diversion pipe.

[0009] Optionally, the closing assembly includes a rotating rod, which is positioned near the inlet of the diversion pipe, and a closing plate is fixedly connected to the outside of the rotating rod.

[0010] Optionally, the rotating rod is fixedly connected to a rotating shaft at both ends, and a support block is provided outside the rotating shaft. The support block is fixedly connected to one side of the diversion pipe.

[0011] Optionally, a worm spring is fixedly connected to the outside of the rotating shaft, and the end of the worm spring away from the rotating shaft is fixedly connected to the inside of the support block.

[0012] Optionally, a flow plate is fixedly connected inside the irrigation pipe, and a water inlet is opened inside the flow plate, which is located inside the flow plate near the squeezing plate.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] This invention employs a sealing plate that detaches from the positioning plate, allowing the sealing plate to drive the closing plate to seal the inlet. This allows water to spray out from the sprinkler hole for sprinkler irrigation. When drip irrigation is needed, the water pressure is reduced, and the water flows along the inlet into the distribution pipe, allowing it to drain along the drip hole for drip irrigation. This improves the switching efficiency between drip irrigation and sprinkler irrigation. Attached Figure Description

[0027] Example

[0028] like Figures 1 to 3As shown, this utility model proposes a dual-mode drip irrigation water-saving device for farmland, including an irrigation pipe 1. Drip irrigation holes 3 are provided on the outer side of the irrigation pipe 1, with multiple sets of holes arranged in a circular array. The drip irrigation holes 3 can be placed on the soil for drip irrigation. A branch pipe 2 is fixedly connected inside the irrigation pipe 1. An inlet 4 is provided on the side of the branch pipe 2 closest to the inside of the irrigation pipe 1. The part of the branch pipe 2 furthest from the inlet 4 is connected to the drip irrigation holes 3. Water flows into the branch pipe 2 through the inlet 4, allowing the water to be transmitted to the drip irrigation holes 3 for drip irrigation. A positioning plate 5 is fixedly connected inside the irrigation pipe 1. A sprinkler hole 19 is provided on the outside of the irrigation pipe 1, away from the drip irrigation hole 3. When the water flow impact force is too large, it will spray out from the sprinkler hole 19 for sprinkler irrigation. A water inlet hole 8 is provided inside the positioning plate 5, which can transmit water flow. A sealing plate 7 is abutted against the positioning plate 5 near the distribution pipe 2. A flow hole 9 is provided inside the sealing plate 7, which can also transmit water flow. A sliding rod 6 is fixedly connected to the sealing plate 7 near the positioning plate 5. The sliding rod 6 is slidably connected inside the positioning plate 5. The water inlet hole 8 and the flow hole 9 are arranged in an intersecting manner. The intersection of the water inlet hole 8 and the flow hole 9 allows the sealing plate 7 to seal the water inlet hole 8.

[0029] For further details, please refer to Figure 2 and Figure 3 A squeezing plate 12 is fixedly connected to the end of the sliding rod 6 away from the sealing plate 7. A spring 10 is fixedly connected to the side of the squeezing plate 12 near the sliding rod 6. The squeezing plate 12 can restrict the sliding of the sliding rod 6. The end of the spring 10 away from the squeezing plate 12 is fixedly connected to the side of the positioning plate 5 away from the sealing plate 7. When the water pressure is too high, the spring 10 will be compressed by the squeezing plate 12. The spring 10 is set outside the sliding rod 6. A closing assembly is set at the top of the diversion pipe 2. The closing assembly includes a rotating rod 15. The rotating rod 15 is set at the position of the diversion pipe 2 near the water inlet 4. The rotating rod 15 can allow the closing plate 16 to rotate outside the diversion pipe 2. The closing plate 16 is fixedly connected to the outside of the rotating rod 15. The closing plate 16 can close the position of the water inlet 4.

[0030] For further details, please refer to Figures 3 to 5 The rotating rod 15 is fixedly connected to the two ends of the rotating shaft 18. The rotating rod 15 rotates by the rotating shaft 18. The rotating shaft 18 is provided with a support block 17 outside the rotating shaft 18. The support block 17 can support the rotating shaft 18. The support block 17 is fixedly connected to one side of the diversion pipe 2. The rotating shaft 18 is fixedly connected with a worm spring 21 outside the rotating shaft 18. The worm spring 21 can control the rotating shaft 18 to return to its original position. The end of the worm spring 21 away from the rotating shaft 18 is fixedly connected to the inside of the support block 17. The irrigation pipe 1 is fixedly connected with a flow plate 13 inside the flow plate 13. The flow plate 13 has a water inlet 14 inside. The water inlet 14 can control the water flow position. The water inlet 14 is located inside the flow plate 13 near the squeezing plate 12.

[0031] In this embodiment, during drip irrigation, low-pressure water is input along the flow plate 13. At this time, the water flows into the irrigation pipe 1 along the water inlet 14. Then, the low-pressure water flows into the gap between the positioning plate 5 and the diversion pipe 2. The water flows into the diversion pipe 2 along the water inlet 4. In this way, the water can be output from the irrigation pipe 1 along the drip irrigation hole 3, thus enabling drip irrigation.

[0032] When the water pressure impact force increases, the water flow impacts the squeezing plate 12 along the water inlet 14. At this time, the water flow will drive the squeezing plate 12 to squeeze the spring 10. In this way, the squeezing plate 12 drives the sliding rod 6 to slide along the inside of the positioning plate 5. The water flow can then flow into the irrigation pipe 1 from the water inlet 8 and the flow hole 9. At this time, the water flow can be sprayed out from the sprinkler hole 19, and sprinkler irrigation can be carried out.

[0033] After the sealing plate 7 moves, the sealing plate 7 will gradually press against the closing plate 16. At this time, the closing plate 16 can cover the water inlet 4, which can prevent water from flowing out from the drip irrigation hole 3, thereby increasing the internal pressure of the irrigation pipe 1 and ensuring that water can be sprayed from the sprinkler hole 19.

[0034] After the water pressure decreases, the spring 10 will push the squeezing plate 12, causing the squeezing plate 12 to slide the sliding rod 6, thereby resetting the sealing plate 7 and sealing the water inlet 8. After the sealing plate 7 disengages from the closing plate 16, the worm spring 21 will drive the rotating shaft 18 to rotate inside the support block 17. This will cause the rotating shaft 18 to rotate the rotating rod 15 to reset, thereby allowing the closing plate 16 to disengage from the water inlet 4 and open.

[0035] It should be noted that this device uses a sealing plate 7 to detach from the positioning plate 5, thereby allowing the sealing plate 7 to drive the closing plate 16 to seal the water inlet 4. This allows water to be sprayed out from the sprinkler hole 19 for sprinkler irrigation. When drip irrigation is needed, the water pressure is reduced, and the water can enter the diversion pipe 2 along the water inlet 4, allowing the water to be discharged along the drip irrigation hole 3. This improves the switching efficiency between drip irrigation and sprinkler irrigation.

[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
