Technical Field
[0001] This utility model relates to the field of irrigation equipment technology, and in particular to an integrated irrigation equipment for farmland water and fertilizer. Background Technology
[0002] As a key technology combining water-saving irrigation and precision fertilization in modern agriculture, the core of fertigation technology lies in integrating soluble fertilizers into irrigation water in a specific ratio through irrigation structures, thereby achieving simultaneous water and fertilizer supply to crops. This technology not only significantly improves water and fertilizer utilization efficiency and reduces resource waste, but also helps improve the soil environment and promote crop growth. It has been widely applied in field crops, facility agriculture, orchards, and cash crop cultivation, becoming one of the important technical means to promote agricultural modernization and sustainable development. Existing integrated water and fertilizer equipment typically includes fertilizer tanks, mixing devices, conveying pipelines, and spraying components. Its working principle is to use a water pump to extract and mix water and fertilizer solution in proportion, and then transport it to the field for irrigation through pipelines. Some equipment is also equipped with simple filtration devices to prevent impurities from clogging the nozzles. However, in actual use, fertilizer solutions often contain incompletely dissolved particles or impurities, which easily accumulate during transportation, causing blockages in pipes or nozzles, affecting irrigation uniformity and equipment lifespan. Furthermore, existing equipment has limited mixing effects, imprecise water-fertilizer ratio control, and insufficient pressure regulation, making it difficult to adapt to the irrigation needs of different crops and soil conditions. Therefore, a well-structured and functionally complete integrated water and fertilizer irrigation system is needed to solve these problems. This paper proposes an integrated water and fertilizer irrigation system for farmland to address these issues. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides an integrated irrigation equipment for farmland, which aims to improve the problem of inconvenience in changing irrigation methods in the existing technology.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: An integrated irrigation device for farmland water and fertilizer includes a fertilizer tank, a conveying pipe fixedly connected to the left side of the fertilizer tank, a filter mechanism fixedly connected to the left side of the conveying pipe, a pressure reducing mechanism fixedly connected to the left side of the filter mechanism, a spreading pipe fixedly connected to the left side of the pressure reducing mechanism, a pressure reducing mechanism including a pressure reducing chamber, a shell fixedly connected to the top of the pressure reducing chamber, a button slidably connected inside the shell, a spring fixedly connected to the bottom of the button, a column fixedly connected to the bottom of the spring, a sliding column fixedly connected inside the button, a connecting column fixedly connected to the bottom of the column, a pressure reducing plate fixedly connected to the bottom of the connecting column, a pipe fixedly connected to one side of the pressure reducing chamber, a sealing ring fixedly connected to one side of the pipe, and a mixing component fixedly connected to the left side of the conveying pipe.

As a further description of the above technical solution: The filtration mechanism includes a tank body, a feed pipe fixedly connected to the right side of the tank body, a bottom plate fixedly connected inside the feed pipe, a rotating pipe fixedly connected to one side of the bottom plate, multiple hollow columns fixedly connected to both sides of the rotating pipe, a removal pipe fixedly connected to the top of the hollow columns, a removal head fixedly connected to the top of the removal pipe, a filter screen fixedly connected to one side of the feed pipe, a discharge pipe fixedly connected to the left side of the tank body, a first recovery pipe fixedly connected to one side of the discharge pipe, a long pipe fixedly connected to one side of the first recovery pipe, and a second recovery pipe fixedly connected to one side of the long pipe. As a further description of the above technical solution: The left side of the conveying pipe is fixedly connected to the right side of the barrel, and the outer wall of the stirring plate is in contact with the inner wall of the barrel. As a further description of the above technical solution: The left side of the barrel is fixedly connected to the right side of the feed pipe, and one side of the recovery pipe is fixedly connected to one side of the rotating pipe.

As a further description of the above technical solution: The left side of the discharge pipe is fixedly connected to the right side of the pipe, and the inner wall of the pipe is fixedly connected to the outer wall of the pipe. As a further description of the above technical solution: The outer side of the column is provided with a groove, and the outer wall of the sliding column is slidably connected to the inner wall of the groove.
[0005] This utility model has the following beneficial effects: 1. In this utility model, by operating the button of the pressure reducing mechanism, the internal sliding column is pushed to slide along the groove of the column and compress the spring. Then, the pressure reducing plate is moved through the connecting column, changing the gap between it and the inside of the pressure reducing chamber, thereby adjusting the cross-sectional area of the fluid channel and realizing continuous and precise control of the fluid pressure in the pipeline. Users can flexibly choose different irrigation modes such as spraying and drip irrigation according to crop type, growth stage and soil conditions, which significantly improves the adaptability of the equipment to different agronomic requirements and effectively overcomes the problems of single mode and complicated adjustment of traditional irrigation devices.
[0006] 2. In this utility model, when the filtration mechanism is running, impurities in the liquid are initially captured by the impurity removal head and further intercepted by the filter screen. Impurities attached to the filter screen and impurity removal tube enter the hollow column under the action of the fluid and enter the recovery path formed by the series connection of recovery pipe one, long pipe and recovery pipe two with the return flow. Finally, they are transported back to the tank of the mixing component. This process realizes the automatic removal and directional transfer of impurities, avoids the accumulation in the filter component, and forms a complete self-cleaning and resource recycling cycle, ensuring the continuity and stability of irrigation operations, while reducing the frequency of daily maintenance and resource waste.

[0009] 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.
[0010] Example: A farmland water and fertilizer integrated irrigation equipment, referring to Figures 1 to 3 The system includes a fertilizer tank 1, which stores and initially dissolves solid or liquid fertilizer. A delivery pipe 2 is fixedly connected to the left side of the fertilizer tank 1, which transports the fertilizer solution to the subsequent processing unit. A filter mechanism 4 is fixedly connected to the left side of the delivery pipe 2, which intercepts and removes solid impurities and suspended particles in the fertilizer solution to prevent drippers or nozzles from clogging. A pressure reducing mechanism 5 is fixedly connected to the left side of the filter mechanism 4, which adjusts the high-pressure fluid in the delivery pipe 2 to the stable low pressure required for drip irrigation or sprinkler irrigation to ensure uniform water output at the terminal. A spreading pipe 6 is fixedly connected to the left side of the pressure reducing mechanism 5, which distributes the treated water-fertilizer mixture evenly to the farmland.
[0011] Specifically, after the fertilizer dissolves in the tank 31, it enters the filter mechanism 4 through the delivery pipe 2, where impurities are intercepted. The clean fertilizer solution flows into the pressure reducing mechanism 5 for pressure stabilization, and finally, the low-pressure water and fertilizer is evenly sprayed or dripped to the crop roots through the spreading pipe 6, achieving efficient irrigation and fertilization.
[0012] The pressure-reducing mechanism 5 includes a pressure-reducing chamber 51, which provides a sealed cavity. A housing 52 is fixedly connected to the top of the pressure-reducing chamber 51, providing sealed protection for the internal adjusting components. A button 53 is slidably connected inside the housing 52, which changes the preload of the internal spring 54 by pressing it, thereby setting the output pressure value. A spring 54 is fixedly connected to the bottom of the button 53, providing adjustable rebound force. A column 55 is fixedly connected to the bottom of the spring 54, transmitting the pressure of the spring 54 to the connecting column 57 below. A sliding column 56 is fixedly connected inside the button 53, sliding within the inner hole of the housing 52 to provide precise guidance for the button 53. The bottom of the column 55... A connecting column 57 is fixedly connected, which reliably transmits the pressure from the upper mechanism. A pressure reducing plate 58 is fixedly connected to the bottom of the connecting column 57, which receives the pressure from the connecting column 57 and adjusts the flow area by changing the opening between it and the valve port to achieve pressure reduction and stabilization. A pipe 59 is fixedly connected to one side of the pressure reducing chamber 51, which connects the inlet and outlet to form a fluid channel. A sealing ring 510 is fixedly connected to one side of the pipe 59, which ensures the sealing of the connection of the pipe 59 and prevents high-pressure fluid leakage. A mixing component 3 is fixedly connected to the left side of the conveying pipe 2, which fully mixes the irrigation water and fertilizer during the conveying process to ensure uniform water and fertilizer.
[0013] Specifically, the operator adjusts the compression of the spring 54 by pressing button 53. The spring force is transmitted through the column 55 and the connecting column 57, driving the pressure reducing plate 58 to change its opening. When the inlet pressure increases, the force of the fluid acting on the lower surface of the pressure reducing plate 58 increases, pushing it upward to compress the spring 54, thus reducing the opening and increasing the resistance, thereby reducing the outlet pressure. Conversely, when the inlet pressure decreases, the spring 54 pushes the pressure reducing plate 58 downward, increasing the opening and decreasing the resistance, thus causing the outlet pressure to rise again, thereby achieving automatic pressure stabilization.
[0014] The mixing component 3 includes a barrel 31, which provides a closed mixing chamber for thorough mixing and blending of water and fertilizer. A cover plate 32 is fixedly connected to the top of the barrel 31, which seals the top of the barrel 31 and provides a mounting base for the drive motor 33. The motor 33 is fixedly connected to the top of the cover plate 32, which provides the core rotational power for mixing. A rotating column 34 is fixedly connected to the drive end of the motor 33, which transmits the torque of the motor 33 downwards. Rotating blades 35 are fixedly connected to the outside of the rotating column 34, which generate vortices at high speed to cut and disperse fertilizer particles, promoting their rapid dissolution in water. Both sides of the rotating column 34 are fixedly connected to... Multiple long columns 36 are connected to increase the mixing radius and avoid mixing dead zones in the tank. A stirring plate 37 is fixedly connected to one side of the long column 36. Its function is to scrape and stir the fluid near the inner wall of the tank 31 to improve the overall mixing uniformity. An arc-shaped plate 38 is fixedly connected to the bottom of the rotating column 34. Its function is to disturb the fertilizer sediment at the bottom of the tank, prevent it from caking and allow it to re-participate in the mixing cycle. A water pump 39 is fixedly connected to one side of the tank 31. Its function is to pump out the mixed uniform fertilizer solution and provide pressure to make it enter the delivery pipe 2. A water inlet pipe 310 is fixedly connected to the drive end of the water pump 39. Its function is to connect to the water source and introduce irrigation water into the mixing tank 31.
[0015] Specifically, motor 33 drives rotating column 34 to rotate, which in turn drives rotating blade 35, long column 36, stirring plate 37 and arc plate 38 to rotate synchronously. Rotating blade 35 generates vortex to achieve main body mixing, stirring plate 37 scrapes the fluid near the barrel wall, and arc plate 38 disturbs the sediment at the bottom of the barrel, thereby achieving all-round efficient mixing. The uniform fertilizer solution is pumped out by water pump 39 and transported to the subsequent pipeline.
[0016] Reference Figure 2 and Figure 4The filtration mechanism 4 includes a tank 41, which provides a sealed filtration space. A feed pipe 42 is fixedly connected to the right side of the tank 41, which introduces the fertilizer solution to be filtered into the tank 41, guiding the fluid to contact the filter elements in a specific flow direction. A base plate 43 is fixedly connected inside the feed pipe 42, providing a stable mounting base for the rotating pipe 44. The rotating pipe 44 is fixedly connected to one side of the base plate 43, rotating under external power to drive the impurity removal components on it, preventing impurities from accumulating on the filter screen surface. Multiple hollow columns 45 are fixedly connected to both sides of the rotating pipe 44, connecting their internal cavities to the rotating pipe 44 to form a backwash channel. A impurity removal pipe 46 is fixedly connected to the top of the hollow column 45, which... During the process, impurities are physically removed. The top of the impurity removal pipe 46 is fixedly connected to the impurity removal head 47, which directly contacts the filter screen. Its special shape can effectively remove blockages while reducing damage to the filter screen. The feed pipe 42 is fixedly connected to one side of the filter screen 48, which intercepts solid particles and suspended impurities in the fertilizer solution through its precision aperture to ensure clean effluent. The left side of the tank body 41 is fixedly connected to the discharge pipe 49, which discharges the filtered clean fertilizer solution. The discharge pipe 49 is fixedly connected to one side of the discharge pipe 49, which recovers impurities. The recovery pipe 410 is fixedly connected to one side of the recovery pipe 410, which connects and fixes the recovery pipeline. The recovery pipe 411 is fixedly connected to one side of the long pipe 411, which guides impurities into the tank body 31.
[0017] Specifically, the fertilizer solution flows into the tank 41 through the feed pipe 42, and after being filtered by the filter screen 48, the clean liquid is output through the discharge pipe 49. During operation, the rotating pipe 44 drives the impurity removal pipe 46 and the impurity removal head 47 to rotate, continuously scraping the inner surface of the filter screen to prevent clogging. Impurities are injected into the tank 31 through the second recovery pipe 412, the long pipe 411 and the first recovery pipe 410, so as to realize the recycling of resources.
[0018] The left side of the conveying pipe 2 is fixedly connected to the right side of the barrel 31. Its function is to reliably convey the fertilizer solution initially dissolved in the fertilizer barrel 1 to the mixing component 3 for further stirring and blending. The outer wall of the stirring plate 37 is always in contact with the inner wall of the barrel 31. Its function is to scrape the inner wall of the barrel 31 during rotation to prevent fertilizer from adhering to and settling on the wall surface and to eliminate mixing dead corners. The left side of the barrel 31 is fixedly connected to the right side of the feed pipe 42. Its function is to directly convey the evenly mixed water-fertilizer solution to the filtration mechanism 4. One side of the recovery pipe 410 is fixedly connected to one side of the rotating pipe 44. Its function is to discharge impurities. One side of the recovery pipe 412 is connected to one side of the barrel 31. Its function is to introduce impurities into the mixing component 3 to realize the internal circulation and reuse of the liquid medium. The right side of the discharge pipe 49 is fixedly connected to the left side of the tank 41. Its function is to reliably discharge the filtered clean fertilizer solution from the bottom of the filtration mechanism 4.
[0019] Specifically, the mixed fertilizer solution enters the feed pipe 42 of the filtration mechanism 4 from the left side of the barrel 31, and is discharged through the discharge pipe 49 after filtration. When recovering impurities, the liquid is led from the long pipe 411 to the second recovery pipe 412 through the first recovery pipe 410 and injected into the barrel 31 for resource recovery. The stirring plate 37 constantly scrapes the barrel wall to ensure uniform mixing and no sedimentation.
[0020] The left side of the discharge pipe 49 is fixedly connected to the right side of the pipe 59. Its function is to reliably transport the filtered clean fertilizer solution from the filter mechanism 4 to the inlet of the pressure reducing mechanism 5. The inner wall of the pipe 59 is fixedly connected to the outer wall of the sealing ring 510. Its function is to use the elastic deformation of the sealing ring 510 to achieve static sealing at the connection of the pipe 59. The outer side of the column 55 is provided with a groove. Its function is to provide a precise sliding track and movement space for the end of the sliding column 56. The outer wall of the sliding column 56 is slidably connected to the inner wall of the groove. Its function is to perform precise axial linear movement under the constraint of the groove, and to transmit the operating force of the button 53 to the spring 54 without deviation.
[0021] Specifically, the filtered fertilizer solution enters the pressure reducing mechanism 5 pipe 59 through the discharge pipe 49. When the operator presses the button 53, the drive column 56 slides axially in the groove of the column body 55, compresses the spring 54 and pushes the column body 55 down. The opening of the pressure reducing plate 58 is changed through the connecting column 57, thereby precisely adjusting the output pressure. The sealing ring 510 ensures that the connection of the pipe 59 is completely sealed without leakage.
[0022] The implementation principle of this embodiment is as follows: After the equipment is started, the water pump 39 delivers irrigation water to the tank 31 of the mixing component 3 through the inlet pipe 310. At the same time, the fertilizer solution in the fertilizer tank 1 is injected synchronously through the delivery pipe 2. The motor 33 starts and drives the rotating column 34 to rotate. The rotating blades 35 fixed on the rotating column 34 work together with multiple stirring plates 37 to achieve full stirring and mixing of the water-fertilizer solution. The arc-shaped plate 38 assists in guiding the fluid movement and avoids sedimentation at the bottom. The fully mixed liquid then enters the filtration mechanism 4. In the filtration mechanism 4, the liquid enters through the feed pipe 42. The liquid flows through the bottom plate 43 and impacts the rotating pipe 44, causing the hollow column 45 and the top impurity removal pipe 46 and impurity removal head 47 to rotate. Solid impurities in the liquid are captured by the impurity removal head 47 and further intercepted by the filter screen 48. The clean liquid flows out through the discharge pipe 49, while the intercepted impurities enter the first recovery pipe 410 under the cooperation of fluid power and structure. Through the recovery passage formed by the long pipe 411 and the second recovery pipe 412, it flows back to the tank 31 of the mixing component 3, realizing the automatic cleaning of impurities and the recycling of resources, effectively avoiding blockage and reducing maintenance needs.
[0023] The mixed liquid enters the pipe 59 of the pressure reducing mechanism 5 through the discharge pipe 49. The user can press the button 53 to push the sliding column 56 inside to slide along the groove of the column 55, compressing the spring 54. This, in turn, drives the pressure reducing plate 58 to move through the connecting column 57, changing its opening in the pressure reducing chamber 51. This allows for precise adjustment of the fluid pressure flowing out of the pipe 59. Operators can flexibly adjust the output pressure according to the actual farmland irrigation needs (such as crop type, soil moisture, etc.) to adapt to the pressure requirements of different irrigation modes such as drip irrigation and sprinkler irrigation. Ultimately, the fertilizer solution is applied to the farmland evenly and accurately through the spreading pipe 6.
[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
