Description

Technical Field

[0001] This application relates to the field of agricultural equipment technology, and in particular to a main-path integrated water and fertilizer intelligent irrigation regulating valve group. Background Technology

[0002] In the field of agricultural irrigation, traditional irrigation methods have many drawbacks. Farmers previously relied heavily on flood irrigation, resulting in significant water waste. Statistics show that approximately 70%-80% of irrigation water is wasted without being fully absorbed by crops. Furthermore, manual fertilization is not only labor-intensive but also difficult to control precisely, easily leading to soil compaction and low fertilizer utilization. Meanwhile, with the increasing scale of agriculture, the demand for automation and intelligence in irrigation systems is growing.

[0003] A search revealed Chinese Patent Publication No. CN119014194A, which discloses an integrated water and fertilizer intelligent irrigation system. The system includes an environmental monitoring module, a water and fertilizer regulation module, and an integrated water and fertilizer machine. The environmental monitoring module includes a meteorological environmental monitoring station and a soil moisture monitoring station. The system acquires meteorological parameters in real time through the meteorological environmental monitoring station and soil parameters in real time through the soil moisture monitoring station. The integrated water and fertilizer intelligent irrigation system provided by this invention acquires meteorological and soil parameters in real time through the environmental monitoring module, sets up drip irrigation units, ground-insulated micro-sprinkler units, and hanging micro-sprinkler units, and automatically calculates irrigation volume, timing, and water-fertilizer ratio based on meteorological and soil parameters, combined with information from each irrigation unit and crop data. This effectively improves water and fertilizer utilization efficiency, reduces water and fertilizer waste, optimizes the crop growth environment, enhances agricultural production efficiency, and promotes sustainable resource utilization.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following deficiencies: the devices do not describe the fine-tuning of the irrigation components, nor do they clearly explain how the irrigation components precisely adjust the water volume and water-fertilizer ratio according to different crop growth stages, soil moisture, and weather conditions. In modern agricultural production, different crops have significantly different water and nutrient requirements at different growth stages. The lack of fine-tuning capabilities makes it difficult to meet the precise irrigation needs of crops, fails to fully utilize the advantages of integrated water and fertilizer systems, reduces resource utilization efficiency, and affects crop yield and quality. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a main-path integrated water and fertilizer intelligent irrigation regulating valve group.

[0006] The present application provides a main-path integrated water and fertilizer intelligent irrigation regulating valve group, which adopts the following technical solution: a main-path integrated water and fertilizer intelligent irrigation regulating valve group, including: a water pumping pipe, one end of which is connected to a water source and the other end of which is connected to a water pump;

[0007] A circulating filtration assembly, located on the outlet side of the water pump, includes a first filter tank and a second filter tank connected in series. The first filter tank contains a rigid coarse filter screen, dividing its inner cavity into upper and lower parts. A slag discharge port is located at the top, and the bottom is connected to the lower half of the second filter tank via a connecting pipe. The second filter tank contains a fine filter screen, dividing its inner cavity into upper and lower parts. A servo motor is fixedly installed at the top of the first filter tank, with its drive shaft extending into the tank. A scraper is fixedly connected to the drive shaft of the servo motor and movably fits against the top surface of the rigid coarse filter screen, with a distance of 0.5-2 mm between the scraper and the rigid coarse filter screen. A water-fertilizer integrated tank is connected to the lower half of the first filter tank via an electrically controlled shut-off valve, and its outlet is connected to an irrigation assembly.

[0008] The above scheme forms a complete intelligent irrigation process integrating water and fertilizer, ensuring smooth water treatment and transportation.

[0009] Furthermore, the rigid coarse filter screen has a pore size of 1-3 mm, and the fine filter screen has a pore size of 0.1-0.5 mm, forming a two-stage gradient filtration structure.

[0010] The above method enables graded filtration of impurities of different particle sizes, thereby improving the purity of irrigation water.

[0011] Furthermore, the scraper is an arc-shaped metal sheet whose curvature is adapted to the inner wall curvature of the first filter tank, and the scraper edge is provided with flexible scraping strips for removing adhering impurities from the surface of the hard coarse filter screen.

[0012] The above method effectively cleans impurities from the coarse filter screen while protecting it from damage.

[0013] Furthermore, the servo motor is a stepper motor, configured to drive the scraper to rotate according to the pressure sensor signal or timing command inside the first filter tank, with a rotation speed of 5-20 r / min.

[0014] The above solution enables intelligent control of the scraper for slag removal, balancing efficiency and energy saving.

[0015] Furthermore, the inlet of the transfer pipe is located on the side wall of the lower half of the first filter tank, and the outlet is inclined and inserted into the lower half of the second filter tank to form a self-flowing anti-clogging channel.

[0016] The above solution utilizes water flow characteristics to reduce the risk of clogging in the circulating filter components.

[0017] Furthermore, a sealing ring is provided between the rigid coarse filter screen and the inner wall of the first filter tank to prevent unfiltered water from flowing into the lower half of the cavity through the gap.

[0018] The above solution ensures that the first filtration tank is airtight, guaranteeing the quality of water used in subsequent processes.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. This utility model employs a two-stage gradient filtration system. A rigid coarse filter intercepts larger particles (1-3mm) to prevent clogging of subsequent systems, while a fine filter removes minute impurities (0.1-0.5mm), ensuring high cleanliness of irrigation water, reducing wear on sprinklers and drippers, and extending equipment lifespan. Simultaneously, a scraper driven by a servo motor efficiently cleans impurities from the coarse filter with a reasonable spacing, ensuring effective scraping without damaging the filter. It can also operate according to pressure or timer commands, resulting in energy efficiency. The connecting pipe forms a self-flowing anti-clogging channel, reducing the risk of blockage and ensuring stable component operation. Furthermore, the sealing ring between the rigid coarse filter and the tank ensures that only filtered water enters subsequent stages, guaranteeing reliable filtration. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0027] This application discloses a main-path integrated water and fertilizer intelligent irrigation regulating valve group.

[0028] Please see Figure 1 A main-path integrated water and fertilizer intelligent irrigation regulating valve group includes: a water pumping pipe 1, one end of which is connected to a water source and the other end is connected to a water pump 2.

[0029] Please see Figures 2 to 4 The circulating filter assembly 3 is located on the outlet side of the water pump 2 and includes a first filter tank 301 and a second filter tank 307 connected in series. The first filter tank 301 is equipped with a rigid coarse filter screen 302, which divides its inner cavity into upper and lower parts. The top is equipped with a slag discharge port 305, and the bottom is connected to the lower half of the second filter tank 307 through a transfer pipe 306. The second filter tank 307 is equipped with a fine filter screen 308, which divides its inner cavity into upper and lower parts. A servo motor 303 is fixedly installed on the top of the first filter tank 301, and its drive shaft extends into the tank. A scraper 304 is fixedly connected to the drive shaft of the servo motor 303 and movably fits against the top surface of the rigid coarse filter screen 302. The distance between the scraper 304 and the rigid coarse filter screen 302 is 0.5-2mm. A water-fertilizer integrated tank 313 is connected to the lower half of the first filter tank 301 through an electrically controlled shut-off valve 312, and its outlet is connected to an irrigation assembly.

[0030] The rigid coarse filter 302 has a mesh size of 1-3mm, and the fine filter 308 has a mesh size of 0.1-0.5mm, forming a two-stage gradient filtration structure.

[0031] The scraper 304 is an arc-shaped metal sheet whose curvature is adapted to the inner wall curvature of the first filter tank 301. The scraper 304 has flexible scraping strips on its edge to remove the attached impurities on the surface of the hard coarse filter screen 302.

[0032] The servo motor 303 is a stepper motor, configured to drive the scraper 304 to rotate according to the pressure sensor signal or timing command in the first filter tank 301, with a rotation speed of 5-20 r / min.

[0033] The inlet of the transfer pipe 306 is located on the side wall of the lower half of the first filter tank 301, and the outlet is inserted at an angle into the lower half of the second filter tank 307, forming a gravity-flow anti-clogging channel.

[0034] A sealing ring is provided between the rigid coarse filter screen 302 and the inner wall of the first filter tank 301 to prevent unfiltered water from flowing into the lower half of the cavity through the gap.

[0035] Further explanation is needed regarding filtration: The circulating filter assembly 3 constructs a rigorous two-stage filtration system. The rigid coarse filter 302 in the first filter tank 301, with its 1-3mm mesh size, can efficiently intercept larger particulate impurities in the water flow, such as silt, small stones, and weed fragments. These impurities are blocked in the upper part, while the purified water flows into the lower part, initially ensuring water quality. Subsequently, the water flows into the second filter tank 307 through the transfer pipe 306, where the fine filter 308, with its 0.1-0.5mm mesh size, further removes tiny impurities, such as algae and fine sand particles, greatly improving the cleanliness of the irrigation water. This effectively prevents these impurities from causing wear on precision components such as sprinklers and drippers in the irrigation assembly, extending the service life of the equipment.

[0036] To maintain system stability, the circulating filter assembly 3, driven by a servo motor 303, rotates the scraper 304 periodically or according to pressure sensor signals, scraping the impurities accumulated on the hard coarse filter screen 302 towards the slag discharge port 305 to maintain the filtration performance of the coarse filter screen. The self-flowing anti-clogging channel formed by the transfer pipe 306 utilizes the water's own gravity and pressure difference to allow water to flow naturally into the second filter tank 307, reducing the risk of blockage caused by poor water flow or impurity accumulation, and ensuring the stable operation of the entire circulating filter assembly. In addition, the sealing ring between the hard coarse filter screen 302 and the inner wall of the first filter tank 301 prevents unfiltered water from flowing into the lower half of the cavity through the gap, ensuring that only qualified filtered water enters the subsequent stages, further guaranteeing the reliability of system operation.

[0037] The implementation principle of a main-path integrated water and fertilizer intelligent irrigation regulating valve group in this application embodiment is as follows:

[0038] First, the water pump 2 is connected to the water source through the water pumping pipe 1. After starting, it draws water from the water source and pressurizes it, so that the water flows into the circulating filter component 3 at high speed, providing a water source foundation for the subsequent purification and distribution process.

[0039] Secondly, the water flows into the first filter tank 301 in the circulating filter assembly 3. The rigid coarse filter screen 302 inside the tank plays a preliminary filtration role. Its 1-3mm mesh size can effectively intercept larger particulate impurities in the water, such as mud, small stones, weeds, and debris. These impurities are blocked in the upper part. At the same time, the servo motor 303 drives the scraper 304 to rotate at a speed of 5-20r / min according to the pressure difference signal detected by the pressure sensor at both ends of the filter screen, or according to the preset timing command. This scrapes the impurities accumulated on the surface of the rigid coarse filter screen 302 to the slag discharge port 305 for discharge, ensuring that the coarse filter screen works continuously and efficiently. The purified water then flows into the lower part of the first filter tank 301.

[0040] Next, the water in the lower half of the first filter tank 301 flows into the second filter tank 307 through the transfer pipe 306, relying on its own gravity and the water pressure inside the tank. In the second filter tank 307, the fine filter screen 308 performs secondary filtration on the water flow with a mesh size of 0.1-0.5mm, further removing tiny impurities such as algae and fine sand particles, ensuring that the water entering the subsequent stages meets the high cleanliness requirements for irrigation.

[0041] Next, the clean water, after two stages of filtration, flows into the integrated water and fertilizer tank 313 under the precise control of the electrically controlled shut-off valve 312. The electrically controlled shut-off valve 312 can flexibly adjust the water flow rate according to irrigation needs and preset programs, so that the water and fertilizer are fully mixed in the integrated water and fertilizer tank 313 in a suitable ratio, and a water and fertilizer solution that meets the needs of different growth stages of crops is prepared.

[0042] Finally, the well-mixed water and fertilizer solution flows out from the outlet of the water and fertilizer tank 313 and connects to the irrigation component. The irrigation component, based on the actual layout of different scenarios such as farmland, orchards or greenhouses and the needs of crop planting, accurately delivers the water and fertilizer solution to the roots of crops through equipment such as sprinklers and drip irrigation pipes, to achieve efficient water and fertilizer integrated irrigation and provide sufficient water and nutrients for crop growth.
