[0035] Example 1
[0036] like Figures 1 to 4 As shown, a water and fertilizer frequency conversion integrated device includes an inlet pipe 11 for connecting to a water source. The other end of the inlet pipe 11 is connected to a centrifugal filter 21, which performs primary filtration of the water source, separating heavy impurities such as sand and pebbles from the water through gravity and centrifugal force.

The other end of the sand storage tank 23 is connected to a drain pipe 12, which discharges heavier impurities such as silt and sand. The dual filtration of the centrifugal filter 21 and the mesh filter 22 effectively removes impurities, silt, and suspended solids from the irrigation water, preventing these impurities from entering the water and fertilizer frequency conversion integrated device, thereby protecting the device and extending its service life.
[0037] The water purification pipe 1 is connected to the water supply pipe 16, which is connected to the box 3 and is used to provide filtered water to the water and fertilizer mixing component 32; the water purification pipe 1 is also connected to the water outlet pipe 13 for irrigating farmland.
[0038] The water purification pipe 1 is also connected to the fertilizer solution tank 4, which is used to inject clean water into the fertilizer solution tank 4;
[0039] The other end of the fertilizer tank 4 is connected to the fertilizer delivery pipe 14, which is used to transport fertilizer liquid.
[0040] The housing 3 is equipped with a water pump 31, a water-fertilizer mixing component 32, a controller 7, and a frequency converter 6. The water inlet pipe 16 is connected to the inlet of the water pump 31, which controls the water flow rate and water pressure of the water inlet pipe 16. The outlet of the water pump 31 is connected to the inlet of the water-fertilizer mixing component 32. The fertilizer inlet of the water-fertilizer mixing component 32 is connected to the fertilizer delivery pipe 14, which is used to deliver fertilizer solution. The water-fertilizer mixing component 32 accurately mixes the fertilizer solution in the fertilizer tank 4 with the filtered water according to the set fertilizer application amount, realizing simultaneous water and fertilizer application. The water-fertilizer mixing component 32 can be a venturi fertilizer applicator or a syringe pump, etc. The outlet of the water-fertilizer mixing component 32 is connected to a water-fertilizer pipe 15, which is connected to the outlet pipe 13.

[0044] The frequency converter 6 is installed on the side wall of the enclosure 3. The frequency converter 6 will automatically adjust the speed of the water pump 31 according to the actual water demand and pipeline pressure to adjust the water flow of the water inlet pipe 16.
[0045] When the soil moisture sensor detects that the soil moisture is below the preset standard value, or the soil nutrient sensor detects that the soil nutrients are below the standard value, the controller 7 will control the water pump 31 according to the set program. The frequency converter 6 will automatically adjust the speed of the water pump 31 according to the actual water demand and pipeline pressure. When a large amount of irrigation is needed, the speed of the water pump 31 will be increased to increase the water flow. When the irrigation demand is small, the speed of the water pump 31 will be reduced to maintain the stability of the pipeline water pressure, realize constant pressure irrigation, ensure the uniformity and stability of irrigation, and help save water and electricity energy.
[0046] Compared to existing technologies, the water and fertilizer frequency conversion integrated device disclosed in this utility model embodiment integrates the frequency converter 6 with the water and fertilizer mixing component 32. Relying on various external sensors, it adopts advanced control algorithms and intelligent management systems to achieve precise control and optimized adjustment of the water and fertilizer frequency conversion integrated device.

[0047] Example 2
[0048] Improvements based on Example 1:
[0049] like Figures 1 to 4 As shown, flow meters are installed on the inlet pipe 11, the clean water pipe 1, the outlet pipe 13, the fertilizer delivery pipe 14, the water and fertilizer pipe 15, and the water supply pipe 16. The flow meters will monitor the flow rate of water and fertilizer solution in the pipes in real time to ensure the accuracy of irrigation and fertilization.
[0050] Furthermore, each pipeline is equipped with a solenoid valve 8, and the controller 7 controls the flow rate of the pipeline by controlling the opening and closing of the solenoid valve 8.
[0051] Furthermore, a check valve 9 is installed on the water outlet pipe 13. The check valve 9 can effectively prevent water and fertilizer from flowing back into the water and fertilizer frequency converter when there is no water in the pipe.
[0052] Furthermore, a stirring motor 41 is installed on the fertilizer solution tank 4, the stirring motor 41 passes through the fertilizer solution tank 4, and a stirring rod is installed inside the fertilizer solution tank 4. The stirring motor 41 can stir the fertilizer solution evenly, effectively preventing the fertilizer solution from solidifying and settling inside the tank.
[0053] Furthermore, a touch screen 33 is installed on the housing 3, allowing operators to observe the operation status of the water and fertilizer frequency conversion integrated device and set various operating parameters to achieve automatic operation.
[0054] Furthermore, the controller 7 is connected to a communication module and a mobile terminal. The communication module is used for data transmission of the controller 7. Operators can remotely view various data of soil and irrigation water and the operating status of the water and fertilizer frequency conversion integrated device in real time through the mobile terminal device, as well as remotely operate and control irrigation and fertilization.
[0055] Furthermore, the controller 7 is also electrically connected to a storage unit, which can store and analyze the collected data, provide farmers with historical data queries, help farmers better understand the growth environment and water and fertilizer requirements of crops, further optimize irrigation and fertilization programs, and improve the efficiency and quality of agricultural production.
[0056] The working principle of this utility model:
[0057] like Figures 1 to 4 As shown, before irrigation, connect the water inlet pipe 11 to the water source, add fertilizer solution to the fertilizer solution tank 4, and set different sensing thresholds, irrigation time, irrigation volume and irrigation frequency according to different irrigation areas, crop types and growth stages, and then turn on the water and fertilizer frequency conversion device.
[0058] During irrigation, water enters centrifugal filter 21 through inlet pipe 11. Centrifugal filter 21 uses gravity and centrifugal force to move heavier impurities such as sand and pebbles along the pipe wall and collect them in sand storage tank 23. The impurities are finally discharged through drain pipe 12. The water that has undergone preliminary filtration enters mesh filter 22. Mesh filter 22 filters impurities through the mesh of the filter element. The purified water that has undergone secondary filtration enters water purification pipe 1. Part of the purified water in water purification pipe 1 enters water-fertilizer mixing component 32 through water pump 31, part enters fertilizer tank 4 to supply water to fertilizer tank 4, and part enters outlet pipe 13 through check valve 9 for irrigation. At the same time, the fertilizer in fertilizer tank 4 is transported into water-fertilizer mixing component 32 by fertilizer delivery pipe 14 and mixed with water. The mixed water-fertilizer is transported to outlet pipe 13 through water-fertilizer pipe 15 and finally irrigates the farmland.
[0059] During irrigation, pressure sensor 51 transmits water pressure data in inlet pipe 11, flow sensor 52 transmits flow data in clean water pipe 1, pH sensor and EC sensor transmit acidity and conductivity data of water-fertilizer mixture, and temperature sensor and nutrient sensor transmit soil temperature, moisture and nutrient content data to controller 7. Controller 7 compares and analyzes the received information with preset standard values and then transmits it to frequency converter 6.
[0060] When the soil moisture sensor detects that the soil moisture is below the preset standard value, or when the soil nutrient sensor detects that the soil nutrients are below the standard value, the controller 7 will control the water pump 31 according to the set program. The frequency converter 6 will automatically adjust the speed of the water pump 31 according to the actual water demand and pipeline pressure. When a large amount of irrigation is needed, the speed of the water pump 31 will be increased to increase the water flow. When the irrigation demand is small, the speed of the water pump 31 will be reduced to maintain the stability of the pipeline water pressure, achieve constant pressure irrigation, and ensure the uniformity and stability of irrigation.
[0061] However, as is well known to those skilled in the art, the working principles and wiring methods of the pressure sensor 51, flow sensor 52, controller 7, frequency converter 6, and water pump 31 are commonplace and belong to conventional methods or common knowledge. Therefore, they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0063] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
