Description
Technical Field
[0001] This invention relates to an agricultural irrigation device that is easy to clean and is situated within the field of agricultural irrigation equipment. Background Technology
[0002] With the continuous advancement of high-standard farmland construction in China, water-saving sprinkler irrigation has gradually replaced traditional flood irrigation and is widely used in the planting of field grains, fruits and vegetables, and horticultural cash crops. Due to the limited distribution of water resources, most farmland irrigation water comes from rivers, canals, ponds, and shallow groundwater, which contain a large amount of fine silt, aquatic plant debris, and suspended algae.
[0003] Existing irrigation pipelines are mostly laid using a single, bonded pipe installation. These pipes are laid close to the ground and are constantly immersed in mud and water in the fields. Sun and rain exposure accelerate the aging and leakage of the pipes. The supporting poles are at a fixed height, making them unsuitable for undulating ridges and slopes. In soft soil, the supports are not firmly rooted and are prone to tipping or bending under water pressure or strong winds. Moreover, the pipelines are made of a single piece and cannot be disassembled into sections. If a single section is damaged, the entire pipe must be replaced, resulting in significant waste of pipe materials. The laying length cannot be flexibly adjusted according to the crop planting row spacing. At the same time, the spraying angle cannot be freely adjusted, and it is only possible to spray upwards on the leaves or downwards to irrigate the soil, making it difficult to simultaneously irrigate the crop canopy and roots. Summary of the Invention
[0004] In view of the shortcomings of the prior art, the present invention discloses an agricultural irrigation device that is easy to clean, which is composed of multiple pipes and multiple connectors spliced together in sections. The entire pipeline is fixed at the middle of the plant height through connectors. One end of the outermost pipe is connected to the water inlet, and the other end of the pipeline away from the water source is uniformly connected to a pulse drain valve. The system includes a circular pipe with a two-part fixed frame at the opening. The cylinder is inserted into the circular hole to achieve a sealed water connection. The inner cavity is divided into independent water distribution chambers by two partitions, and the water is evenly distributed to the two obliquely arranged cavities on both sides. Filter holes are opened on the outside of the cavities to pre-filter the water and remove sediment during water intake, reducing impurities from entering the nozzles and causing blockages. The connecting frame slides circumferentially along the groove inside the fixed frame via a middle plate, allowing free rotation to change the spray angle of the nozzles. This enables flexible switching between two irrigation modes: spraying upwards on plant leaves and spraying downwards on crop roots. The semi-open connecting frame structure allows for quick disassembly and maintenance of the filter screen by removing and installing fasteners. Circular holes are opened on the outside of the circular pipe. The section of the round tube near the round hole is designated as a reduced diameter section. A fixed frame is installed on the outer side of the round tube near the round hole. The fixed frame is a semi-circular ring structure, and there are two fixed frames. The two fixed frames form a ring by fasteners. A connecting frame is rotatably connected to the outer side of the fixed frame. The connecting frame adopts an open ring structure. The two ends of its open side are fastened together by fasteners. The fasteners can be loosened to achieve quick assembly and disassembly of the connecting frame. An extension tube is fixedly connected to the outer side of the connecting frame. A nozzle is threadedly connected to the outer side of the extension tube. There are two connecting frames, and the two connecting frames are symmetrically arranged at both ends of the fixed frame. Two nozzles are arranged on the two connecting frames, tilted upwards and tilted downwards respectively.
[0005] Furthermore, the fixed frame has an inner cavity in the middle, and the outer circumferential surface of the fixed frame is machined with annular grooves of alternating concave and convex shapes. The connecting frame is nested in the corresponding grooves to achieve circumferential positioning and fixation. A cylinder is fixedly connected to the middle of the inner wall of the fixed frame. A circular hole penetrates the fixed frame and extends into the inner cavity. The cylinder is located inside the circular hole on the cylindrical tube. Two partitions are fixedly connected to the inner cavity. The two partitions form a fan-shaped space in the inner cavity. Two cavities are opened inside the fixed frame. The two cavities are arranged obliquely opposite each other and are located on the two fixed frames respectively. Filter holes are opened on the outer side of the fixed frame near the cavity. Two intermediate plates are fixedly connected to the outer side of the fixed frame. The two intermediate plates are set on both sides of the filter holes. A sliding groove is opened on the inner wall of the connecting frame. The intermediate plates are slidably connected to the sliding groove.
[0006] Furthermore, the nozzle includes a cylinder, which is threaded to the outer side of an extension cylinder. The cylinder communicates with the interior of the cavity through the extension cylinder and filter holes. The cylinder is designed with a widened diameter in the middle, forming a cavity structure that is thicker in the middle and thinner at both ends. The widened diameter in the middle of the cylinder forms a water storage and pressure stabilizing cavity. When there are instantaneous water pressure fluctuations, the cavity buffers and stabilizes the pressure. The water flow rate from each side hole is consistent, and the spray radius is uniform and stable, preventing scouring by large amounts of water nearby and drought in distant areas, thus improving the uniformity of irrigation in the field. A positioning cylinder and a conical cylinder are fixedly connected to the inner wall of the cylinder. The positioning cylinder and the conical cylinder are located at the connection between the middle section and both ends of the cylinder. The positioning cylinder is located on the side closer to the extension cylinder. A square plate is slidably connected to the inner wall of the cylinder near the extension cylinder. A positioning rod is fixedly connected to the middle of the square plate. A ball is fixedly connected to the end of the positioning rod away from the square plate. The nozzle is driven by a spring, the square plate, and the positioning rod. The moving sphere forms a one-way sealing structure. Water pressure opens the sphere to spray water. After water supply stops, the spring returns to its original position, pushing the sphere to press firmly against the positioning cylinder, sealing the water path to prevent dripping and leakage, and avoiding localized waterlogging and root rot in the field. The conical cylinder is densely covered with side holes, resulting in a dispersed and gentle water output that is uniform and does not easily wash away soil compaction. The nozzle is threadedly connected to the extension cylinder, which can be easily disassembled by unscrewing for convenient cleaning after blockage. The sphere is located in the gap between the conical cylinder and the positioning cylinder. Multiple limiting plates are fixedly connected to the outside of the sphere, and these plates are evenly distributed around the sphere. The limiting plates are slidably connected to the inner wall of the cylinder. The conical cylinder has multiple side holes evenly distributed on its outer side. A spring is installed inside the cylinder, with both ends of the spring fixedly connected to the square plate and the positioning cylinder, respectively.
[0007] Furthermore, the connector includes an intermediate pipe, with threaded connections at the ends of the intermediate pipe and the round pipe. The connector uses the threaded connection of the intermediate pipe to the round pipe to achieve segmented assembly of the pipeline. The convex ring in the middle of the intermediate pipe cooperates with the split frame for clamping and limiting. The bottom of the pipeline is supported by a connecting rod, a sliding cylinder, and a ground support. It is fixed by a pair of opposite magnetic positioning posts that cooperate with the slots to attract and clamp, making it less prone to lodging and displacement in soft farmland soil. Multiple sets of slots on the outer wall of the sliding cylinder can be used to finely adjust the support height of the support as needed, adapting to undulating fields. The segmented pipeline is easy to disassemble and assemble; if there is partial damage, only the single section of the pipe needs to be replaced, without disassembling the entire pipe. The intermediate pipe is designed with a reduced-width section. A convex ring is fixedly connected to the middle of the outer side of the intermediate pipe. A frame is set on the outer side of the intermediate pipe near the convex ring. There are two frames, and the two frames are connected by fasteners to form a single unit. A circular frame has two shells fixedly connected to its outer side near the fasteners. The shells cover the ends of the frame. A connecting rod is fixedly connected to the bottom of the shell. A sliding cylinder is slidably connected to the outer side of the connecting rod. The outer side of the sliding cylinder has multiple slots evenly arranged. A positioning post is slidably connected to the outer side of the connecting rod away from the shell. The positioning post is magnetic. There are two positioning posts, and their magnetic properties are opposite. A support column is fixedly connected to the bottom of the sliding cylinder. An intermediate ring is fixedly connected to the middle of the inner wall of the frame. A convex ring cooperates with the intermediate ring to limit the movement of the pipeline. The frame hugs the convex ring tightly, restricting the axial movement of the pipeline. The joint is not easy to loosen and leak water when subjected to field water pressure impact or soil settlement. There are two convex rings, located on both sides of the intermediate ring.
[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: This is an easy-to-clean agricultural irrigation device. The opening of the round pipe is equipped with a two-part combined fixing frame. The round cylinder is inserted into the round hole to achieve a sealed connection of the water path. The inner cavity is divided by two partitions to form an independent water distribution chamber. The water is evenly distributed to the two obliquely arranged cavities on both sides. Filter holes are opened on the outside of the cavities to pre-filter the water and sediment when water enters, reducing the amount of impurities entering the nozzle and causing blockage. The connecting frame slides around the circumference of the fixed frame through the middle plate, which can freely rotate to change the spray angle of the nozzle, realizing flexible switching between two irrigation modes: spraying upward on the plant leaves and spraying downward on the crop roots.
[0009] (II) This type of agricultural irrigation equipment is easy to clean. The nozzle is equipped with a one-way sealing structure formed by a spring, a square plate, and a positioning rod. When the water supply pressure opens the ball, water is sprayed. After the water supply stops, the spring returns to its original position and pushes the ball to press against the positioning cylinder, sealing the water path to prevent water leakage and local water accumulation and root rot in the field. The conical cylinder is covered with side holes, so the water is dispersed and gentle, and the water is even and does not easily wash away the soil and cause compaction. The nozzle is connected to the extension cylinder by a thread, and can be disassembled separately by turning it, which is convenient for cleaning after blockage.
[0010] (III) This agricultural irrigation equipment is easy to clean. The connecting parts use a central threaded connection to a round pipe to achieve segmented assembly of the pipeline. The central convex ring of the central pipe cooperates with the split frame to clamp and limit the position. The bottom is supported by the connecting rod, the sliding cylinder and the ground support. It is fixed by a pair of opposite magnetic positioning columns and the grooves to attract and clamp. It is not easy to fall over or move in the soft soil environment of farmland. The multiple sets of grooves on the outer wall of the sliding cylinder can be finely adjusted as needed to adjust the support height of the support column to adapt to the uneven fields. The segmented pipeline is easy to disassemble and assemble. If there is local damage, only the single section of the pipeline needs to be replaced, without the need to remove the entire pipeline.
[0011] (iv) This agricultural irrigation equipment is easy to clean. The cylinder is thickened and expanded in the middle to form a water storage and pressure stabilizing cavity. When the instantaneous water pressure fluctuates, the cavity buffers and stabilizes the pressure. The water flow rate of each side hole is consistent, and the spray radius is uniform and stable, preventing the nearby area from being washed away by large water and the distant area from being short of water and drought, thus improving the uniformity of irrigation in the field.

[0014] Example 1, as Figures 1 to 9 As shown, this embodiment discloses an agricultural irrigation device that is easy to clean. It consists of multiple pipes 1 and multiple connectors 2 spliced together in sections to form a pipeline. The entire row of pipes 1 is fixed at the middle of the plant height through the connectors 2. One end of the outermost pipe 1 is connected to the water inlet, and the other end of the pipeline away from the water source is uniformly connected to the pulse drain valve. The pipe 1 includes a circular pipe 11, with a two-part fixed frame 12 at the opening position of the circular pipe 11. A cylindrical cylinder 16 is inserted into the circular hole 14 to achieve a sealed water connection. The inner cavity 110 is divided by two partitions 17 to form an independent water distribution cavity. The water is evenly distributed to the two obliquely arranged cavities 113 on both sides. Filter holes 19 are opened on the outside of the cavity 113 to pre-filter the water and sediment during water intake, reducing impurities from entering the nozzle 15 and causing blockage. The connecting frame 13 slides circumferentially along the sliding groove 111 in the fixed frame 12 via the middle plate 18, and can freely rotate to change the spray angle of the nozzle, realizing flexible switching between two irrigation modes: spraying upwards on plant leaves and spraying downwards on crop roots. The semi-open connecting frame 13 structure allows for quick disassembly and maintenance of the filter screen by removing and installing fasteners. The circular pipe 11 has a circular hole 14 on its outside. The section of pipe 11 near the circular hole 14 is designated as a reduced diameter section. A fixing frame 12 is provided on the outer side of the circular pipe 11 near the circular hole 14. The fixing frame 12 is a semi-circular ring structure. There are two fixing frames 12. The two fixing frames 12 form a ring through fasteners. A connecting frame 13 is rotatably connected to the outer side of the fixing frame 12. The connecting frame 13 adopts an open ring structure. The two ends of its open side are fastened together by fasteners. The fasteners can be loosened to achieve quick disassembly and assembly of the connecting frame 13. An extension tube 112 is fixedly connected to the outer side of the connecting frame 13. A nozzle 15 is threadedly connected to the outer side of the extension tube 112. There are two connecting frames 13. The two connecting frames 13 are symmetrically arranged at both ends of the fixing frame 12. The two nozzles 15 located on the two connecting frames 13 are respectively inclined upward and inclined downward.
[0015] The fixing frame 12 has an inner cavity 110 in the middle. The outer circumferential surface of the fixing frame 12 is machined with annular grooves with alternating concave and convex shapes. The connecting frame 13 is nested in the corresponding groove to achieve circumferential positioning and fixation. A cylinder 16 is fixedly connected to the middle of the inner wall of the fixing frame 12. A circular hole 14 penetrates the fixing frame 12 and extends into the inner cavity 110. The cylinder 16 is located inside the circular hole 14 on the circular tube 11. Two partitions 17 are fixedly connected inside the inner cavity 110. The two partitions 17 form a fan shape in the inner cavity 110. The fixed frame 12 has two cavities 113 inside, which are arranged diagonally opposite each other and located on the two fixed frames 12 respectively. Filter holes 19 are provided on the outer side of the fixed frame 12 near the cavity 113. Two intermediate plates 18 are fixedly connected to the outer side of the fixed frame 12. The two intermediate plates 18 are located on both sides of the filter holes 19. The inner wall of the connecting frame 13 has a sliding groove 111, and the intermediate plates 18 are slidably connected to the sliding groove 111.
[0016] Example 2, based on Example 1, combined with... Figure 6Therefore, the nozzle 15 includes a cylinder 151, which is threaded to the outer side of the extension cylinder 112. The cylinder 151 communicates with the interior of the cavity 113 through the extension cylinder 112 and the filter hole 19. The cylinder 151 is designed with a middle section expansion, forming a cavity structure that is thicker in the middle and thinner at both ends. The thickening and expansion of the middle of the cylinder 151 forms a water storage and pressure stabilizing cavity. When there are instantaneous water pressure fluctuations, the pressure is buffered and stabilized by the cavity. The water flow rate from each side hole is consistent, and the spray radius is uniform and stable, preventing scouring by large amounts of water nearby and drought in distant areas, thus improving the uniformity of irrigation in the field. A positioning cylinder 153 and a conical cylinder 152 are fixedly connected to the inner wall of the nozzle 151. The positioning cylinder 153 and the conical cylinder 152 are located at the connection between the middle section and both ends of the nozzle 151. The positioning cylinder 153 is located on the side closer to the extension cylinder 112. A square plate 156 is slidably connected to the inner wall of the nozzle 151 near the extension cylinder 112. A positioning rod 155 is fixedly connected to the middle of the square plate 156. A ball 154 is fixedly connected to the end of the positioning rod 155 away from the square plate 156. The nozzle 15 is driven by a spring 157, the square plate 156, and the positioning rod 155. The sphere 154 forms a one-way sealing structure. Water pressure opens the sphere 154 to allow water to spray. After water supply stops, spring 157 returns to its original position, pushing the sphere 154 to press firmly against the positioning cylinder 153, sealing the water path to prevent dripping and leakage, and avoiding localized waterlogging and root rot in the field. The conical cylinder 152 is densely covered with side holes 159, resulting in a dispersed and gentle water flow that is even and does not easily erode or compact the soil. The nozzle 15 is threadedly connected to the extension cylinder 112, allowing for easy disassembly and cleaning after blockage. The sphere 154 is located between the conical cylinder 152 and the positioning cylinder 153. At the interval, a limiting plate 158 is fixedly connected to the outer side of the sphere 154. There are multiple limiting plates 158, which are evenly distributed around the sphere 154. The limiting plates 158 are slidably connected to the inner wall of the cylinder 151. A side hole 159 is opened on the outer side of the conical cylinder 152. There are multiple side holes 159, which are evenly distributed on the outer side of the conical cylinder 152. A spring 157 is installed inside the cylinder 151. The two ends of the spring 157 are fixedly connected to the square plate 156 and the positioning cylinder 153, respectively.
[0017] Example 3, based on Examples 1 and 2, combined with... Figures 10 to 11It can be seen that the connector 2 includes an intermediate tube 21, which is threaded to the end of the round tube 11. The connector 2 uses the threaded connection of the intermediate tube 21 to the round tube 11 to realize the segmented assembly of the pipeline. The convex ring 29 in the middle of the intermediate tube 21 cooperates with the split frame 22 to clamp and limit the position. The bottom of the pipeline is supported by the connecting rod 24, the sliding cylinder 25 and the ground support 28. It is fixed by the adsorption and clamping of a pair of opposite magnetic positioning posts 26 and the groove 27, which makes it less likely to fall over and shift in the soft soil environment of farmland. The outer wall of the sliding cylinder 25 has multiple sets of grooves 27, which can be used to finely adjust the support height of the pillars to adapt to uneven fields. The segmented pipeline is easy to disassemble and assemble; if a part is damaged, only a single section of pipe 1 needs to be replaced, without disassembling the entire pipe. The intermediate pipe 21 is designed with a mid-section reduction. A convex ring 29 is fixedly connected to the middle of the outer side of the intermediate pipe 21. A frame 22 is set on the outer side of the intermediate pipe 21 near the convex ring 29. There are two frames 22, which are fastened together to form a circular frame. The frame 22 is close to the outer side of the convex ring 29. A housing 23 is fixedly connected to the outer side of the fastener. There are two housings 23. The housings 23 cover the end of the frame 22. A connecting rod 24 is fixedly connected to the bottom of the housing 23. A slide cylinder 25 is slidably connected to the outer side of the connecting rod 24. A slot 27 is opened on the outer side of the slide cylinder 25. There are multiple slots 27, which are evenly arranged on the outer side of the slide cylinder 25. A positioning post 26 is slidably connected to the outer side of the end of the connecting rod 24 away from the housing 23. The positioning post 26 is magnetic. There are two positioning posts 26, and the magnetic properties of the two positioning posts 26 are opposite. A support column 28 is fixedly connected to the bottom of the slide cylinder 25. An intermediate ring 210 is fixedly connected to the middle of the inner wall of the frame 22. A convex ring 29 cooperates with the intermediate ring 210 to limit the movement. The frame 22 hugs the convex ring 29 to restrict the axial movement of the pipeline. The joint is not easy to loosen and leak water when the field water pressure impacts or the soil settles. There are two convex rings 29, which are located on both sides of the intermediate ring 210.
[0018] In use, the irrigation pipeline is assembled by splicing multiple sections of round pipe 11 with intermediate pipe 21. The support column 28 of the connector 2 is inserted into the ground. According to the height of the plants, the magnetic polarity positioning column 26 is attracted to each other and cooperates with the groove on the outside of the sliding cylinder 25 to adjust the height of the pipeline and complete the fixed-point installation of the field pipeline. Then, after the water source enters from one end of the pipeline, the water flows into the inner cavity 110 of the fixed frame 12 through the reduced diameter section of the round pipe 11, the round hole 14 and the round cylinder 16. Then, it is diverted by the partition 17 into the two oblique cavities 113 on both sides, and sent into the interior of the nozzle 15 through the filter hole 19 and the extension cylinder 112.
[0019] When the water pressure increases, the water pressure pushes the ball 154 to move to one side of the conical cylinder 152 against the elastic force of the spring 157. The water sprays out through the side hole 159 on the conical cylinder 152 to achieve irrigation. After the water pressure decreases, the spring 157 rebounds and pushes the ball 154 to block the channel and prevent leakage. The two sets of nozzles 15, one above and one below, can simultaneously replenish water to the upper canopy and root soil of the crop. At the same time, the fasteners are loosened, so that the connecting frame 13 slides around the circumference of the slide groove 111 in the fixed frame 12 based on the middle plate 18. It can be rotated and adjusted as needed. The spray angle of the long tube 112 and the nozzle 15, combined with the double nozzle arrangement of one above and one below, allows for flexible changes in the range of canopy spraying and root irrigation. The end of the pipeline is equipped with a pulse drain valve, and the pulse high-pressure water flow can backwash the silt and impurities accumulated in the pipe 1, filter hole 19 and nozzle 15. The fixed frame 12 and connecting frame 13 can be quickly disassembled and installed, making it easy to disassemble and clean the blocked parts. With the help of the segmented pipeline structure, the one-way self-sealing nozzle 15 and the end pulse drain combination, normal irrigation and periodic overall drainage and cleaning can be completed simultaneously.
