Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, and in particular to an irrigation device for agricultural planting. Background Technology

[0002] In the modern precision irrigation technology system, drip irrigation systems have become the mainstream irrigation equipment for the cultivation of cash crops such as vegetables, fruit trees, and flowers due to their significant water-saving and energy-saving characteristics and precise water and fertilizer delivery advantages. The existing drip irrigation system architecture covers four core modules: water source, headworks, water distribution network, and drippers. By constructing a fixed pipeline network and dripper array, it achieves precise water and fertilizer supply to the crop root zone.

[0003] However, the locations of the drip irrigation pipes and drip holes in current drip irrigation systems are fixed during installation. When replanting or additional planting occurs during the growth of surrounding crops, or when crops in a local area are removed due to disease, the original drip irrigation layout is difficult to adapt to the new planting needs. This can lead to over-irrigation in some areas while the replanted areas cannot receive effective irrigation. Utility Model Content

[0004] In response to the shortcomings of existing drip irrigation systems that are difficult to adapt to new planting needs when replanting or additional planting occurs during the growth of surrounding crops, or when crops in a localized area are removed due to disease, resulting in over-irrigation in some areas while the replanted areas cannot receive effective irrigation, this utility model provides an irrigation device for agricultural planting. It has the advantages of flexible adjustment of the irrigation atmosphere and enhanced applicability, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an irrigation device for agricultural planting, including a water storage tank, a water pump installed at the bottom of the water storage tank via a pipe, a purification box installed on the other side of the water pump via a pipe, three water inlet pipes fixedly installed at the other end of the purification box, a vertical pipe fixedly installed at the other end of the three water inlet pipes, a rotating pipe installed at the top of the vertical pipe, a horizontal pipe fixedly installed at the upper end of the rotating pipe, two extension pipes slidably installed at both ends of the horizontal pipe, multiple irrigation holes are opened at the bottom of the two extension pipes and the horizontal pipe, a concave plate is fixedly installed at one bottom end of the extension pipe, a movable arm is hinged to the inner side of the concave plate, a slide rail is opened on the surface of the rotating pipe, a movable sleeve is installed at the bottom of the outer surface of the rotating pipe, the bottoms of the two movable arms are respectively hinged to the two ends of the movable sleeve, a fixing plate is fixedly installed at the upper end of the rotating pipe, and a first groove is opened on the surface of the fixing plate.

[0006] Preferably, when the two extension tubes are completely inside the horizontal tube, the grouting holes on their surfaces correspond to the grouting holes at the bottom of the horizontal tube. Multiple slots are evenly provided on the side of the first slide groove, and a second slide groove is provided on the surface of the movable sleeve. A limit plate is slidably installed inside the second slide groove, and the inner walls of the movable sleeve are slidably installed inside the slide rails.

[0007] The locking mechanism between the limiting plate and the slot can fix the position of the movable sleeve, ensuring a stable irrigation range during irrigation and preventing the extension pipe from sliding arbitrarily due to external forces.

[0008] Preferably, a compression spring is fixedly installed on one side of the limiting plate in the second slide groove, and the other side of the compression spring is fixedly installed on the inner wall of the second slide groove. The middle part of the limiting plate is slidably installed inside the first slide groove, and the compression spring is engaged in the slot after elastic release.

[0009] By using a compression spring, the elastic release force pushes the limiting plate to automatically engage with the slot, thus automatically locking the position of the movable sleeve and ensuring the stability of the irrigation range after adjustment.

[0010] Preferably, a stop valve is installed at the upper end of the pipe connecting the water pump and the purification box, a filter plate and an activated carbon plate are inserted and installed inside the purification box, and a support plate is fixedly installed at the bottom of the riser.

[0011] By installing filter plates, large particles such as mud, sand, and dead branches in the water source can be intercepted, improving the quality of irrigation water and preventing impurities from clogging subsequent pipes and irrigation holes.

[0012] Preferably, a rotary joint is installed at the upper end of the riser, the bottom of the rotating pipe is rotatably mounted at the upper end of the rotary joint, and a linkage gear is fixedly installed on the bottom surface of the rotating pipe.

[0013] The rotary joint allows the rotating pipe to rotate flexibly relative to the riser, and the linkage gear enables the horizontal pipe to rotate, expanding the irrigation coverage area and ensuring smooth rotation.

[0014] Preferably, a waterproof box is fixedly installed on the upper surface of the riser, a small motor is installed inside the waterproof box, a drive gear is meshed on the side of the linkage gear, and the output end of the small motor is connected to the bottom of the drive gear through a coupling.

[0015] By using a small motor, the active gear is driven to rotate and drive the linkage gear to mesh and transmit power, so that the rotating pipe and horizontal pipe rotate, thereby achieving dynamic expansion and uniform coverage of the irrigation area.

[0016] This utility model has the following advantages:

[0017] 1. By setting extension tubes that slide at both ends inside the horizontal tube, when the movable sleeve slides up and down along the slide rail, the movable arm can drive the extension tube to slide horizontally inside the horizontal tube, thereby adjusting the overall length of the combination of the horizontal tube and the extension tube and changing the coverage range of the irrigation holes. At the same time, the limiting plate is locked in the slot of the fixed plate under the action of the compression spring, restricting the axial position of the movable sleeve. When it is necessary to adjust the irrigation range, the external force pushes the limiting plate to move horizontally against the resistance of the compression spring, so that the limiting plate is disengaged from the slot, the movable sleeve slides upward along the slide rail, and the movable arm pushes the extension tube to extend to both ends of the horizontal tube due to the hinge structure, so that the distribution range of the irrigation holes is expanded. Conversely, when the movable sleeve moves downward, the extension tube retracts into the horizontal tube, reducing the irrigation range, thus realizing the function of flexibly adjusting the irrigation coverage area according to planting needs.

[0018] 2. By installing filter plates and activated carbon plates inside the purification tank, as well as a stop valve between the water pump and the purification tank, water is drawn from the storage tank by the water pump. The stop valve controls the flow before the water enters the purification tank. Inside the purification tank, the filter plates intercept large particles of impurities such as mud and dead branches. The activated carbon plates then adsorb pesticide residues, heavy metals, and other harmful substances, completing the water purification process. The purified water flows through the inlet pipe, riser pipe, transfer pipe, and horizontal pipe, and is evenly dripped from the irrigation holes to the crop roots. This effectively avoids the problems of impurities clogging the irrigation holes and polluting the soil, improves irrigation water quality, ensures healthy crop growth, and extends the service life of the irrigation equipment.

[0027] 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.

[0028] Please see Figures 1-7 An irrigation device for agricultural planting includes a water storage tank 1. A water pump 2 is installed at the bottom of the water storage tank 1 through a pipe. A purification box 3 is installed on the other side of the water pump 2 through a pipe. Three water inlet pipes 4 are fixedly installed at the other end of the purification box 3. A riser pipe 5 is fixedly installed at the other end of the three water inlet pipes 4. A rotating pipe 7 is installed at the top of the riser pipe 5. A horizontal pipe 8 is fixedly installed at the upper end of the rotating pipe 7. Two extension pipes 12 are slidably installed at both ends inside the horizontal pipe 8.

[0029] Multiple pouring holes 13 are provided at the bottom of both extension tubes 12 and the horizontal tube 8. A concave plate 14 is fixedly installed at one end of the bottom of the extension tube 12. A movable arm 17 is hinged to the inner side of the concave plate 14. A slide rail 15 is provided on the surface of the rotating tube 7. By setting the extension tubes 12 that are slidably installed at both ends inside the horizontal tube 8, when the movable sleeve 16 slides up and down along the slide rail 15, the movable arm 17 can drive the extension tube 12 to slide horizontally inside the horizontal tube 8, thereby adjusting the overall length of the horizontal tube 8 and the extension tube 12 after combination, and changing the coverage of the pouring holes 13.

[0030] A movable sleeve 16 is installed on the bottom of the outer surface of the rotating pipe 7. The bottoms of two movable arms 17 are respectively hinged to the two ends of the movable sleeve 16. A fixing plate 18 is fixedly installed on the upper end of the rotating pipe 7. A first groove 19 is opened on the surface of the fixing plate 18. When the movable sleeve 16 slides along the axis of the rotating pipe 7, the movable arms 17 push the extension pipe 12 to extend and retract horizontally in the horizontal pipe 8 through the hinge point. At the same time, the limiting plate 22 on the movable sleeve 16 is locked into the first groove 19 and the slot 20 of the fixing plate 18 under the action of the compression spring 23, locking the position of the movable sleeve 16, thereby fixing the extension and retraction state of the extension pipe 12 and realizing the adjustment and locking of the irrigation range.

[0031] Please see Figures 2-5 When the two extension tubes 12 are completely inside the horizontal tube 8, the grouting holes 13 on their surfaces correspond to the grouting holes 13 at the bottom of the horizontal tube 8. Multiple slots 20 are evenly distributed on the side of the first slide groove 19. A second slide groove 21 is distributed on the surface of the movable sleeve 16. A limiting plate 22 is slidably installed inside the second slide groove 21. The inner walls of the movable sleeve 16 are slidably installed inside the slide rails 15. The limiting plate 22 is engaged in the slots 20 of the fixing plate 18 under the action of the compression spring 23, restricting the movement of the movable sleeve 16. When the axial position of 6 needs to be adjusted, the external force pushes the limiting plate 22 to overcome the resistance of the compression spring 23 and move it laterally, so that the limiting plate 22 is disengaged from the slot 20. The movable sleeve 16 slides upward along the slide rail 15. The movable arm 17 pushes the extension tube 12 to extend to both ends of the horizontal tube 8 due to the hinge structure, so that the distribution range of the irrigation holes 13 is expanded. Conversely, when the movable sleeve 16 moves downward, the extension tube 12 retracts into the horizontal tube 8, reducing the irrigation range. This realizes the function of flexibly adjusting the irrigation coverage area according to planting needs.

[0032] A compression spring 23 is fixedly installed on one side of the limiting plate 22 located in the second slide groove 21. The other side of the compression spring 23 is fixedly installed on the inner wall of the second slide groove 21. The middle part of the limiting plate 22 is slidably installed inside the first slide groove 19. After the compression spring 23 is released elastically, it is locked inside the slot 20. When the compression spring 23 is released elastically, it pushes the limiting plate 22 to slide along the second slide groove 21 and lock into the slot 20 in the first slide groove 19, restricting the movable sleeve 16 to move axially along the rotating tube 7, thereby fixing the position of the extension tube 12 in the horizontal tube 8. When the external force pushes the limiting plate 22 to overcome the spring resistance and disengage from the slot 20, the movable sleeve 16 can slide freely along the slide rail 15, driving the extension tube 12 to adjust the pouring range. After the adjustment is completed, the spring pushes the limiting plate 22 again to lock into the slot 20 and lock the position.

[0033] A stop valve 9 is installed at the upper end of the pipe connecting water pump 2 and purification tank 3. The opening and closing of the stop valve 9 controls the flow of water, facilitating equipment maintenance, repair, or temporary irrigation suspension, thus avoiding water waste. It also provides a safe and isolated environment for replacing or cleaning the filter plates 10 and activated carbon plates 11 inside the purification tank 3, improving the flexibility of operation and ease of maintenance. The purification tank 3 is internally fitted with filter plates 10 and activated carbon plates 11. By setting up the filter plates 10 and activated carbon plates 11 inside the purification tank 3, and the stop valve 9 between water pump 2 and purification tank 3, water is drawn from the storage tank 1 by water pump 2, first controlled by the stop valve 9, and then enters the purification tank 3. Inside the purification tank 3, the filter plates 10 intercept large particles of impurities such as mud, sand, and dead branches in the water before it is further filtered. The activated carbon plate 11 adsorbs pesticide residues, heavy metals and other harmful substances in the water, completing the water purification process. The purified water flows through the inlet pipe 4, riser 5, rotating pipe 7 and horizontal pipe 8, and drips evenly from the irrigation hole 13 to the crop roots. This effectively avoids the problem of impurities clogging the irrigation hole 13 and polluting the soil, improves the quality of irrigation water, ensures the healthy growth of crops, and extends the service life of the irrigation equipment. The bottom of the riser 5 is fixedly installed with a support plate 6. According to the existing technology, the installation position of the irrigation device is usually cast with a concrete pillar to provide an installation foundation for the irrigation pipe. The bottom of the support plate 6 is cast on the concrete pillar with bolts to ensure the stability of the riser 5. The upper end of the riser 5 is installed with a rotary joint 24, and the bottom of the rotating pipe 7 is rotatably installed on the upper end of the rotary joint 24.

[0034] A linkage gear 25 is fixedly installed on the bottom surface of the rotating pipe 7, and a waterproof box 26 is fixedly installed on the upper surface of the riser pipe 5. A small motor 27 is installed inside the waterproof box 26. A drive gear 28 is meshed on the side of the linkage gear 25. The output end of the small motor 27 is connected to the bottom of the drive gear 28 through a coupling. When the small motor 27 is powered on, it drives the drive gear 28 to rotate. The drive gear 28 drives the linkage gear 25 to rotate through meshing transmission. The linkage gear 25 is fixedly connected to the rotating pipe 7, thereby driving the rotating pipe 7 and the horizontal pipe 8 to rotate around the rotary joint 24 at the top of the riser pipe 5. This causes the irrigation hole 13 at the bottom of the horizontal pipe 8 to rotate with the rotating pipe 7, expanding the irrigation coverage area. The waterproof box 26 provides protection for the small motor 27, preventing water from entering and affecting the motor operation.

[0035] Working principle: When in use, first start the water pump 2. The water source in the water storage tank 1 enters the purification tank 3 through the pipe and the water stop valve 9. The water flow first passes through the filter plate 10 to intercept large particles of impurities such as mud and dead branches, and then passes through the activated carbon plate 11 to adsorb harmful substances such as pesticide residues and heavy metals, thus completing the water purification.

[0036] The purified water is delivered to the riser 5 through the inlet pipe 4. At this time, the small motor 27 starts and its output drives the drive gear 28 to rotate. The drive gear 28 meshes with the linkage gear 25, so that the rotating pipe 7 rotates at the top of the riser 5 through the rotary joint 24. The horizontal pipe 8 rotates synchronously with the rotating pipe 7, and the bottom irrigation hole 13 begins to drip evenly.

[0037] When the irrigation range needs to be adjusted, the external force pushes the limiting plate 22 inside the second slide trough 21 to move laterally and squeeze the compression spring 23, disengaging it from the slot 20 of the fixed plate 18 and releasing the limitation on the movable sleeve 16. The movable sleeve 16 slides upward along the slide rail 15 on the surface of the rotating pipe 7. The movable arms 17 hinged on both sides change their angle due to the force, pushing the extension pipe 12 to slide horizontally to both ends inside the horizontal pipe 8. At this time, the extension pipe 12 and the irrigation hole 13 at the bottom of the horizontal pipe 8 form a longer distribution array, expanding the irrigation coverage area.

[0038] Conversely, when the external force causes the movable sleeve 16 to move downward, the extension tube 12 retracts into the horizontal tube 8, and the distribution range of the irrigation holes 13 shrinks. After the adjustment is completed, the compression spring 23 is released elastically, and the limiting plate 22 is re-engaged into the slot 20 to fix the position of the movable sleeve 16 and ensure the stability of the irrigation range during the irrigation process.
