[0001] This utility model relates to the field of farmland irrigation technology, specifically to an irrigation device with a filtration mechanism. Background Technology

[0002] In the field of agricultural production, farmland irrigation is a key link in ensuring crop growth and increasing yield. Especially in areas that rely on natural water sources for irrigation, how to use water resources efficiently and ensure irrigation water quality directly affects agricultural production efficiency and crop quality.

[0003] However, existing farmland filtration irrigation devices still have problems affecting irrigation continuity and ease of maintenance in actual use. When the device needs to replace or maintain the core filter components, it is often necessary to stop water extraction and irrigation operations. Otherwise, water leakage and blockage of water channels may occur, leading to irrigation interruption. This not only affects the normal water supply to crops but also reduces the overall irrigation efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an irrigation device with a filtration mechanism. This device features the advantage that the replacement of the filter box can be achieved without stopping the river water pumping, ensuring continuous irrigation, through the cooperation of the sealing component and the connecting component. Furthermore, the device can effectively intercept and clean impurities in the river water through the retrieval component to prevent the sealing component from becoming clogged. This solves the problem that irrigation needs to be interrupted when replacing the filter components in existing devices.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an irrigation device with a filtration mechanism, comprising a box body, a partition fixedly installed in the middle of the box body, two filter boxes symmetrically and movably installed inside the box body, L-shaped tubes symmetrically and fixedly installed at both ends of the box body, one end of the L-shaped tube penetrating the box body, a threaded groove opened on the outer side of the end of the L-shaped tube penetrating the box body, a rectangular water inlet pipe fixedly installed at the other end of the L-shaped tube, a sealing component provided inside the end of the L-shaped tube penetrating the box body, connecting hoses fixedly installed at both ends of the filter boxes, a connecting component provided at the end of the connecting hose away from the filter box, the sealing component and the connecting component working together, a T-shaped pipe fixedly installed between the two L-shaped tubes at the other end of the box body, a rectangular hole opened at the top of the rectangular water inlet pipe, a retrieval component provided at the top of the rectangular water inlet pipe, the connecting component consisting of a tapered tube and a tapered sealing plate, and the connecting component consisting of an installation tube and a top rod.

[0006] As a preferred technical solution of this utility model, the sealing assembly includes a tapered tube, which is fixedly installed inside one end of the L-shaped tube that penetrates the box body. Three brackets are fixedly installed at equal intervals along the circumference inside the end of the tapered tube near the filter box, and an installation ring is fixedly installed between the three brackets.

[0007] As a preferred embodiment of the present invention, the sealing assembly further includes a conical sealing plate, which is disposed at the other end of the conical tube. A spring is fixedly installed on the side of the conical sealing plate near the conical tube, and the other end of the spring is fixedly installed on one side of the mounting ring. Sealing rings are fixedly installed at both ends of the conical tube.

[0008] As a preferred technical solution of this utility model, the connecting component includes an installation tube, which is fixedly installed at one end of the connecting hose. A threaded sleeve is rotatably installed on the outside of the installation tube. The threaded sleeve is threadedly connected to one end of the L-shaped tube that penetrates the box. An insertion tube is fixedly installed at one end of the installation tube near the L-shaped tube. The insertion tube is movably sleeved inside one end of the L-shaped tube that penetrates the box.

[0009] As a preferred technical solution of this utility model, the connecting assembly further includes three brackets II, which are fixedly installed at equal intervals along the circumference inside the insertion tube. A top rod is fixedly installed between the three brackets II, and the top rod passes through the mounting ring. The top rod is used in conjunction with the conical sealing plate.

[0010] As a preferred embodiment of this utility model, the salvage assembly includes a filter plate, which is fixedly installed inside a rectangular inlet pipe and near a rectangular hole. A motor is fixedly installed on the top of the rectangular inlet pipe, and two brackets are fixedly installed on the top of the rectangular inlet pipe. The rectangular hole is located between the two brackets. A rotating rod is fixedly installed at the output end of the motor, and the rotating rod passes through the two brackets.

[0011] As a preferred technical solution of this utility model, the salvage assembly further includes a plurality of salvage rods, which are fixedly installed at equal intervals along the circumference on the outside of the rotating rod. Two rectangular rods are fixedly installed on the top of the rectangular water inlet pipe, and the positions of the rectangular rods correspond to the positions of the bracket three. A guide plate is fixedly installed between the two rectangular rods, and a plurality of rectangular grooves are opened on the top of the guide plate, the positions of the rectangular grooves corresponding to the positions of the salvage rods.

[0012] As a preferred embodiment of this utility model, a first arc-shaped hook is fixedly installed at the end of the retrieval rod, and a plurality of second arc-shaped hooks are fixedly installed at the end of the guide plate near the retrieval rod. The first arc-shaped hooks and the second arc-shaped hooks are arranged in opposite directions, and the guide plate is inclined.

[0013] The beneficial effects of this utility model are as follows: This invention, through the cooperation of the sealing component and the connecting component, ensures a tight and stable connection between the filter box and the L-shaped tube. When the installation pipe is connected to the L-shaped tube through the threaded sleeve, the insertion tube is inserted into the L-shaped tube, and the push rod pushes the conical sealing plate to overcome the spring traction force, causing the conical sealing plate to separate from the conical tube. At this time, river water can smoothly pass through the L-shaped tube and the connecting hose into the filter box. When not connected, the conical sealing plate is tightly fitted to the conical tube under the action of the spring, effectively preventing river water leakage and ensuring the overall sealing performance and water flow stability of the device.

[0014] The motor drives the rotating rod to rotate, which in turn causes the retrieval rod to rotate. The first arc-shaped hook at the end of the retrieval rod can scoop up the water plants intercepted by the filter plate during rotation. The inclined setting of the guide plate and the presence of the second arc-shaped hook on it not only help the retrieval rod to further intercept impurities, but also allow the scooped water plants to slide down along the guide plate to a designated position for easy collection and cleaning.

However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0018] Figures 1-11 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 11 The present invention will be further described below.

[0019] An irrigation device with a filtration mechanism includes a housing 1. A partition is fixedly installed in the middle of the interior of the housing 1. Two filter boxes 3 are symmetrically and movably installed inside the housing 1. L-shaped pipes 2 are symmetrically fixedly installed at both ends of the housing 1. One end of the L-shaped pipe 2 penetrates the housing 1, and a threaded groove is opened on the outer side of the end of the L-shaped pipe 2 penetrating the housing 1. A rectangular water inlet pipe 4 is fixedly installed at the other end of the L-shaped pipe 2 penetrating the housing 1. A sealing component is provided inside the end of the L-shaped pipe 2 penetrating the housing 1. Connecting hoses 5 are fixedly installed at both ends of the filter boxes 3. A connecting component is provided at the end of the connecting hose 5 away from the filter box 3. A tee pipe is fixedly installed between the two L-shaped pipes 2 at the other end of the housing 1. A rectangular hole 16 is opened at the top of the rectangular water inlet pipe 4. A retrieval component is provided at the top of the rectangular water inlet pipe 4. The connecting component consists of a tapered pipe 11 and a tapered sealing plate 15. The connecting component consists of an installation pipe 6 and a top rod 9.

[0020] In this implementation scheme, the housing 1 provides the installation foundation for the entire farmland filtration and irrigation device. Internal partitions divide the interior of housing 1, and four positioning blocks are symmetrically fixed inside housing 1 to limit the installation position of the filter box 3. The filter box 3 is filled with activated carbon filter media, which effectively removes impurities such as silt, algae, and humus from the river water, providing clean irrigation water for the farmland. One end of the L-shaped pipe 2 penetrates housing 1, connecting the external water source and the internal filtration structure. The other end has a rectangular inlet pipe 4 that allows river water to enter. The outer threaded groove is threadedly connected to the threaded sleeve 10, connecting to the connecting hose 5, thus conveying river water. The rectangular inlet pipe 4 serves as the inlet channel for river water into the device. The rectangular hole 16 allows river water to enter while facilitating the retrieval rod 20 in the retrieval component to remove larger impurities such as aquatic plants. The sealing component is located inside the end of the L-shaped pipe 2 that penetrates housing 1, enabling filtration... The sealing or connection control between the filter box 3 and the L-shaped pipe 2 allows the sealing component to be activated during filter box 3 replacement without stopping the river water extraction, ensuring irrigation continuity and improving irrigation efficiency. The connecting hose 5 connects the filter box 3 and the L-shaped pipe 2 and has a certain degree of flexibility, allowing it to adapt to the movement of the filter box 3 during replacement, making the connection between the connecting component and the L-shaped pipe 2 more flexible and facilitating the disassembly and assembly of the filter box 3. The connecting component can connect or disconnect the filter box 3 and the L-shaped pipe 2. The three-way pipe is fixedly installed between the two L-shaped pipes 2 at the other end of the box body 1, which can transport the water filtered by the filter box 3 to the farmland for irrigation. The rectangular hole 16 is opened at the top of the rectangular inlet pipe 4 to provide operating space for the retrieval rod 20 and other components of the retrieval component, allowing the retrieval rod 20 to retrieve river water impurities in the rectangular inlet pipe 4 through the rectangular hole 16. The retrieval component can retrieve and process water plants and other impurities intercepted by the filter plate 17.

[0021] Specifically, the sealing assembly includes a tapered tube 11, which is fixedly installed inside one end of the L-shaped tube 2 that penetrates the housing 1. Three supports 12 are fixedly installed at equal intervals along the circumference inside the end of the tapered tube 11 near the filter box 3, and an installation ring 13 is fixedly installed between the three supports 12.

[0022] In this embodiment, the tapered tube 11 is fixedly installed inside one end of the L-shaped tube 2 that penetrates the housing 1, providing a basic mounting frame for the sealing assembly. The brackets 12 are fixedly installed equidistantly along the circumference inside one end of the tapered tube 11 near the filter box 3. The three brackets 12 form a stable support structure, providing a fixed mounting point for the mounting ring 13. The mounting ring 13 is fixedly installed between the three brackets 12. On the one hand, it provides a fixed support point for one end of the spring 14 in the sealing assembly, ensuring that the spring 14 can be stably connected between the mounting ring 13 and the tapered sealing plate 15, realizing the elastic reset function of the spring 14. On the other hand, the central hole of the mounting ring 13 allows the push rod 9 in the connecting assembly to pass through, providing a guide channel for the push rod 9 to push the tapered sealing plate 15, ensuring that the push rod 9 can accurately act on the tapered sealing plate 15, realizing the opening and closing control of the tapered sealing plate 15 in the sealing assembly.

[0023] Specifically, the sealing assembly also includes a conical sealing plate 15, which is disposed at the other end of the conical tube 11. A spring 14 is fixedly installed on the side of the conical sealing plate 15 near the conical tube 11. The other end of the spring 14 is fixedly installed on one side of the mounting ring 13. Sealing rings are fixedly installed at both ends of the conical tube 11.

[0024] In this embodiment, by placing the conical sealing plate 15 at the other end of the conical tube 11, its shape is adapted to the port of the conical tube 11, and it can form a tight seal with the conical tube 11. Under the action of the traction force of the spring 14, it can tightly fit the port of the conical tube 11 to block the water flow. Under the push of the push rod 9 of the connecting component, it can overcome the traction force of the spring 14 and separate from the conical tube 11 to open the channel. One end of the spring 14 is fixedly installed on the side of the conical sealing plate 15 near the conical tube 11, and the other end is fixedly installed on the side of the mounting ring 13. It achieves the reset function through its own elastic deformation. The sealing ring is fixedly installed at both ends of the conical tube 11, so that the conical tube 11 and the conical sealing plate 15 are sealed when they fit together, and at the same time, the insertion tube 7 is sealed when it fits the other end of the conical tube 11.

[0025] Specifically, the connecting assembly includes an installation tube 6, which is fixedly installed at one end of the connecting hose 5. A threaded sleeve 10 is rotatably installed on the outside of the installation tube 6. The threaded sleeve 10 is threadedly connected to one end of the L-shaped tube 2 that penetrates the housing 1. An insertion tube 7 is fixedly installed at one end of the installation tube 6 near the L-shaped tube 2. The insertion tube 7 is movably sleeved inside the end of the L-shaped tube 2 that penetrates the housing 1.

[0026] In this embodiment, by fixing one end of the installation tube 6 to one end of the connecting hose 5, the connecting hose 5 can be associated with the L-shaped tube 2 through the installation tube 6. The other end is fixedly installed with the insertion tube 7, providing a stable installation base for the insertion tube 7 and ensuring that the insertion tube 7 can be accurately inserted into the L-shaped tube 2. At the same time, its outer side provides a rotation installation point for the threaded sleeve 10. The threaded sleeve 10 is threadedly connected to the threaded groove at one end of the L-shaped tube 2 that penetrates the housing 1. By rotating the threaded sleeve 10, the installation tube 6 can be moved axially, realizing the insertion or withdrawal of the insertion tube 7 into the L-shaped tube 2, thereby controlling the connection or disconnection of the connecting component with the L-shaped tube 2. The threaded connection structure has self-locking properties, which can ensure the stability of the connection between the installation tube 6 and the L-shaped tube 2 and prevent the connection from loosening due to water flow impact during use. The insertion tube 7 is fixedly installed at the end of the installation tube 6 near the L-shaped tube 2. As the installation tube 6 moves, it can be movably sleeved inside the end of the L-shaped tube 2 that penetrates the housing 1, and forms a seal with the sealing ring at one end of the tapered tube 11.

[0027] Specifically, the connecting assembly also includes three brackets 28, which are fixedly installed at equal intervals along the circumference inside the insertion tube 7. A push rod 9 is fixedly installed between the three brackets 28, and the push rod 9 passes through the mounting ring 13. The push rod 9 is used in conjunction with the conical sealing plate 15.

[0028] In this embodiment, by fixing three supports 28 at equal intervals along the circumference inside the insertion tube 7, a stable triangular support structure is formed, ensuring that the top rod 9 and the insertion tube 7 remain coaxial, and preventing the top rod 9 from shifting due to water flow impact or movement of the insertion tube 7. The top rod 9 is fixedly installed between the three supports 28, and can pass through the mounting ring 13 when the insertion tube 7 is inserted into the L-shaped tube 2. By pushing the conical sealing plate 15 at the end to overcome the traction force of the spring 14, the conical sealing plate 15 is separated from the conical tube 11, opening the water passage, allowing river water to enter the filter box 3 from the L-shaped tube 2 through the insertion tube 7, the mounting tube 6, and the connecting hose 5 in sequence. When disassembling, the top rod 9 is removed with the insertion tube 7, and the conical sealing plate 15 is reset and sealed under the action of the spring 14.

[0029] Specifically, the salvage assembly includes a filter plate 17, which is fixedly installed inside the rectangular inlet pipe 4 and close to the rectangular hole 16. A motor 18 is fixedly installed on the top of the rectangular inlet pipe 4, and two brackets 19 are fixedly installed on the top of the rectangular inlet pipe 4. The rectangular hole 16 is located between the two brackets 19. A rotating rod is fixedly installed at the output end of the motor 18, and the rotating rod passes through the two brackets 19.

[0030] In this embodiment, by fixing the filter plate 17 inside the rectangular inlet pipe 4 and near the rectangular hole 16, a porous structure is adopted to directly intercept larger impurities such as water plants and branches carried by the river water flowing in the rectangular inlet pipe 4, preventing these impurities from continuing to flow into the L-shaped pipe 2 with the river water, and avoiding impurities getting stuck in the sealing components in the L-shaped pipe 2. The motor 18 is fixedly installed on the top of the rectangular inlet pipe 4, and its output end is fixedly connected to the rotating rod. After being powered on, it can drive the rotating rod to rotate stably around the axis, providing power for the impurity retrieval action of the retrieval component. Two brackets 19 are symmetrically fixedly installed on the top of the rectangular inlet pipe 4 and distributed on both sides of the rectangular hole 16. The rotating rod passes through the two brackets 19, and the brackets 19 can provide stable support for the rotating rod, preventing the rotating rod from shaking or deviating due to centrifugal force or water flow impact under the drive of the motor 18, and ensuring that the rotating rod always rotates along the fixed axis.

[0031] Specifically, the salvage assembly also includes several salvage rods 20, which are fixedly installed at equal intervals along the circumference on the outside of the rotating rod. Two rectangular rods 21 are fixedly installed on the top of the rectangular water inlet pipe 4. The position of the rectangular rods 21 corresponds to the position of the bracket 19. A guide plate 22 is fixedly installed between the two rectangular rods 21. Several rectangular grooves 23 are opened on the top of the guide plate 22. The position of the rectangular grooves 23 corresponds to the position of the salvage rods 20.

[0032] In this embodiment, several retrieval rods 20 are fixedly installed equidistantly around the outside of a rotating rod, rotating synchronously with the rotating rod under the drive of a motor 18. During rotation, they can extend into the rectangular inlet pipe 4 to directly retrieve water plants and large impurities intercepted by the filter plate 17. Simultaneously, because they correspond to the rectangular groove 23 of the guide plate 22, they can smoothly pass through the rectangular groove 23 to transfer impurities onto the guide plate 22. Two rectangular rods 21 are fixedly installed on the top of the rectangular inlet pipe 4 and correspond to the position of the bracket 19, providing stable support for the guide plate 22 and ensuring that the guide plate 22 maintains a preset tilt angle. The guide plate 22 is fixedly installed between the two rectangular rods 21. The surface can receive impurities transferred from the retrieval rod 20. With its own inclined structure, the impurities are guided to slide out of the rectangular inlet pipe 4, thus achieving the final discharge of impurities. On the other hand, the rectangular groove 23 opened at the top provides a through channel for the retrieval rod 20, preventing the guide plate 22 from blocking the rotation of the retrieval rod 20 and ensuring that the retrieval rod 20 can smoothly complete the impurity transfer action. The groove opening size of the rectangular groove 23 is adapted to the diameter of the retrieval rod 20, allowing the retrieval rod 20 to pass smoothly through the guide plate 22 when rotating. This does not affect the retrieval action of the retrieval rod 20, and when the retrieval rod 20 passes through, the impurities attached to the retrieval rod 20 are scraped off by the edge of the groove opening, so that the impurities remain on the guide plate 22 and slide down along the inclined surface.

[0033] Specifically, a first arc-shaped hook is fixedly installed at the end of the retrieval rod 20, and several second arc-shaped hooks are fixedly installed at one end of the guide plate 22 near the retrieval rod 20. The first arc-shaped hooks and the second arc-shaped hooks are arranged in opposite directions, and the guide plate 22 is inclined.

[0034] In this embodiment, the first arc-shaped hook has a larger contact area with the impurities due to its arc structure, resulting in stronger gripping stability. Especially for easily slippery long and thin impurities such as aquatic plants, the arc-shaped hook can hold the impurities and prevent them from slipping off the retrieval rod 20. At the same time, because it is opposite in direction to the second arc-shaped hook on the guide plate 22, it can form a "reverse scraping" cooperation with the second arc-shaped hook when passing through the rectangular groove 23 of the guide plate 22, ensuring that the impurities are smoothly transferred to the guide plate 22 and reducing impurity residue. The arc structure of the second arc-shaped hook, which is set in the opposite direction, complements the first arc-shaped hook. It can not only avoid blocking the rotation path of the retrieval rod 20, but also accurately act on the impurities on the first arc-shaped hook, enhancing the impurity removal effect and ensuring that the retrieval rod 20 can effectively release impurities after each rotation, improving the efficiency of subsequent retrieval actions. The guide plate 22 is set at an angle, which can guide the impurities transferred to the plate surface to slide quickly out of the rectangular water inlet pipe 4 with the help of gravity, avoiding the accumulation of impurities on the guide plate 22 and ensuring that the impurity discharge channel is unobstructed.

[0035] In summary: When this utility model is in use, a water pump is connected to the rectangular inlet pipe 4. After the water pump is started, it draws river water into the rectangular inlet pipe 4. The river water first flows through the filter plate 17 inside the rectangular inlet pipe 4, near the rectangular hole 16. The filter plate 17, with its porous structure, intercepts larger impurities such as water plants and branches in the river water, preventing these impurities from entering the L-shaped pipe 2 with the river water and causing blockage of the sealing components. At the same time, the motor 18 is connected to an external power source and started. The motor 18 at the top of the rectangular inlet pipe 4 drives the rotating rod at the output end to rotate around the axis. Several scooping rods 20, which are fixed at equal intervals along the circumference on the outside of the rotating rod, rotate synchronously with the rotating rod. The first arc-shaped hook at the end of the scooping rod 20 will hook the impurities intercepted by the filter plate 17. When the retrieval rod 20 rotates to the guide plate 22, because the rectangular groove 23 at the top of the guide plate 22 corresponds to the position of the retrieval rod 20, the retrieval rod 20 can smoothly pass through the rectangular groove 23. At this time, the second arc-shaped hook at the end of the guide plate 22 near the retrieval rod 20 will scrape off the impurities on the first arc-shaped hook. The impurities fall onto the inclined guide plate 22 and slide out of the rectangular inlet pipe 4 along the inclined surface of the guide plate 22. The river water treated by the filter plate 17 and the retrieval assembly enters the L-shaped pipe 2, and then enters the filter box 3 in sequence through the insertion pipe 7, the installation pipe 6, and the connecting hose 5. The activated carbon filter medium filled inside the filter box 3 can remove impurities such as silt, algae, and humus in the river water. The filtered clean water flows out from the filter box 3. The water flows out through the connecting hose 5, installation pipe 6, and L-shaped pipe 2 at the other end, and finally converges through the tee pipe between the two L-shaped pipes 2 at the other end of the box 1, and is uniformly transported to the farmland for irrigation. When the filter box 3 needs to be replaced, there is no need to stop the water pump from drawing river water. One of the filter boxes 3 can be replaced first. Manually rotate the threaded sleeve 10 of the connecting component on the side of the filter box 3 to be replaced, so that the threaded sleeve 10 is separated from the threaded groove on the outside of the L-shaped pipe 2. Then manually pull the installation pipe 6 to drive the insertion pipe 7 out of the L-shaped pipe 2. The top rod 9 fixed by the three brackets 2 8 inside the insertion pipe 7 will be removed with the insertion pipe 7 and separated from the conical sealing plate 15. The conical sealing plate 15 is reset under the traction force of the spring 14 and is tightly attached to the conical pipe 11. The components are combined to form a seal, thereby blocking the water passage of the L-shaped pipe 2 on that side. During this process, because the sealing component seals the corresponding L-shaped pipe 2, the river water is filtered only through another filter box 3. Then, the old filter box 3 is manually removed from the box body 1 and replaced with a new filter box 3 filled with activated carbon filter media. Then, the installation tube 6 on the hose 5 connecting both ends of the new filter box 3 is manually aligned with the corresponding L-shaped pipe 2. The threaded sleeve 10 is rotated so that the installation tube 6 drives the insertion tube 7 to be inserted into the L-shaped pipe 2. The push rod 9 inside the insertion tube 7 passes through the installation ring 13 and pushes the conical sealing plate 15 to overcome the traction force of the spring 14, so that the conical sealing plate 15 is separated from the conical pipe 11, opening the water passage and completing the replacement of the filter box 3. The device continues to operate stably.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
