Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a water-fertilizer integrated sprinkler irrigation device. Background Art

[0002] Integrated irrigation and fertilization refers to a new agricultural technology that integrates irrigation and fertilization. Using a pressure system (or natural terrain drop), this technology combines soluble solid or liquid fertilizers, formulated according to soil nutrient content and the specific fertilizer requirements of the crop species, with irrigation water. This solution is then delivered through a controlled piping system. Once the fertilizer and water are combined, the solution is then applied through pipes and drippers to create a uniform, timed, and quantitative infiltration of the crop's root development areas, ensuring the soil around the root system remains loose and at an optimal moisture content. Integrated irrigation and fertilization technology delivers rapid fertilization and improves nutrient utilization. It avoids volatilization losses and slow dissolution of fertilizers, which can occur when applied to dry topsoil, ultimately leading to slower fertilizer utilization. It particularly avoids volatilization losses of ammonium and urea nitrogen fertilizers applied to the surface, conserving nitrogen fertilizer while benefiting the environment.

[0003] Integrated irrigation and fertilization technology has been widely used in crop seedling cultivation due to its advantages of saving water and fertilizer, improving fertilizer utilization, and saving labor. However, existing integrated irrigation and fertilization sprinkler systems typically adopt a horizontal layout, resulting in a large overall structure, occupying a lot of space after installation, high operating costs, and inconvenient transportation, which has hindered its popularization and application in agricultural production. Therefore, there is an urgent need for integrated irrigation and fertilization equipment with a smaller structure, less installation space, and easy installation and transportation to solve these problems.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example:

[0028] like Figures 1 to 7 As shown, a water-fertilizer integrated sprinkler irrigation device includes a water-fertilizer mixing tank 5 and a base 7. The base 7 is fixedly provided at the bottom of the water-fertilizer mixing tank 5. A stirring motor 12 is assembled on the top of the water-fertilizer mixing tank 5. A stirring shaft 22 is vertically provided inside the water-fertilizer mixing tank 5, and the upper end of the stirring shaft 22 is fixedly connected to the output end of the stirring motor 12. An auger blade 23 is fixedly provided on the annular surface of the stirring shaft 22. A fixed bracket 4 is provided on the upper side of the water-fertilizer mixing tank 5. A feeding box 15 is fixedly provided on the upper side of the fixed bracket 4. A fertilizer box 3 is provided on the upper side of the feeding box 15. A conical guide hopper 19 is fixedly provided on the lower side of the feeding box 15. A feeding pipe 21 is fixedly connected to the lower end outlet of the guide hopper 19, and the lower end of the feeding pipe 21 extends into the water-fertilizer mixing tank 5. A material pump 2 is installed on the top of the fertilizer box 3. The output end of the material pump 2 is connected to the fertilizer box 3 through the feed pipe 13, and its input end is connected to the external fertilizer storage equipment through the fertilizer suction pipe 1. The bottom of the water-fertilizer mixing tank 5 is connected to the liquid outlet pipe 25, and the liquid outlet pipe 25 is equipped with a valve 17. The right end of the liquid outlet pipe 25 is connected to the filter cartridge 8, and the right side of the filter cartridge 8 is connected to the booster water pump 9 through the liquid inlet pipe 27. The output end of the booster water pump 9 is connected to the sprinkler pipe 10, and the right end of the sprinkler pipe 10 is connected to the diversion sprinkler pipe 11. This design solves the problem that the existing water-fertilizer integrated sprinkler irrigation device usually adopts a horizontal layout structure, which leads to a larger overall structure volume, occupies more space after installation, and has a high cost of use and is inconvenient to carry, affecting its popularization and application in agricultural production.

[0029] In this embodiment, a one-way valve 16 is installed on the feeding pipe 21. The one-way valve 16 is used to control the one-way flow of fertilizer in the feeding pipe 21, and at the same time can prevent water vapor from rising into the feeding box 15, preventing water vapor from making the fertilizer particles damp, causing them to deteriorate and affecting the fertility of the fertilizer.

[0030] In this embodiment, a quantitative feeding blade 18 is provided inside the feeding box 15, and a servo motor 14 is installed on the right side of the feeding box 15, and the output end of the servo motor 14 is fixedly connected to the right end of the shaft on the quantitative feeding blade 18. The quantitative feeding blade 18 is set to achieve quantitative feeding of fertilizers. When the feeding blade rotates, it will scoop up a certain amount of fertilizer and transport it to the entrance of the feeding pipe 21. At the same time, by controlling the rotation of the servo motor 14, the rotation speed of the quantitative feeding blade 18 can be accurately controlled, thereby realizing accurate quantitative feeding of fertilizers, and the feeding speed and amount of fertilizers can be adjusted according to actual needs, further improving the automation level and feeding accuracy of the equipment.

[0031] In this embodiment, a glass level gauge 6 is mounted on the front side of the annular surface of the water-fertilizer mixing tank 5 , and the operator can visually observe the liquid level height in the water-fertilizer mixing tank 5 through the glass level gauge 6 .

[0032] In this embodiment, a liquid level sensor 20 is installed on the left side of the top of the water-fertilizer mixing tank 5 . The liquid level sensor 20 is used to monitor the maximum liquid level in the water-fertilizer mixing tank 5 .

[0033] In this embodiment, the auger blade 23 rotates counterclockwise. The counterclockwise rotation of the auger blade 23 can drive the water to flow upward, so that the fertilizer flows upward under the drive of the water flow, which can increase the floating time of the fertilizer in the water, ensure that the fertilizer and water can be fully mixed, help reduce the precipitation of fertilizer at the bottom of the water-fertilizer mixing tank 5, and ensure the uniformity and stability of the mixed liquid. A plurality of groups of spoilers 24 are fixed on the inner wall of the water-fertilizer mixing tank 5, and the inner diameter of the spoiler 24 is larger than the diameter of the auger blade 23. When the auger blade 23 rotates, the spoiler 24 can generate additional disturbances, further break up the agglomerates in the mixed liquid, and improve the mixing uniformity. At the same time, the spoiler 24 can increase the complexity and length of the flow path of the mixed liquid, improve the efficiency of water-fertilizer mixing, and shorten the mixing time.

[0034] In this embodiment, multiple groups of flow guide holes 26 are evenly opened inside the spoiler 24. The design of the flow guide holes 26 can change the flow path of the fluid around the spoiler 24, making the fluid more evenly distributed in the mixing tank, helping to reduce dead corners and short-circuit flow and improve mixing efficiency.

[0035] In this embodiment, the filter cartridge 8 comprises a sealing cap 81, a barrel 82, and a filter screen 83. The sealing cap 81 is threadedly assembled onto the upper side of the barrel 82. A removable filter screen 83 is provided within the barrel 82. The connection between the outlet pipe 25 and the barrel 82 is located above the filter screen 83, while the connection between the inlet pipe 27 and the barrel 82 is located below the filter screen 83. This design allows for filtering the water-fertilizer mixture, retaining solid particles in the liquid, and preventing incompletely dissolved fertilizer from entering the diversion sprinkler pipe 11 and causing blockage. During use, the mixed water-fertilizer liquid enters the barrel 82 through the inlet pipe 27 and flows through the filter screen 83, where it is filtered, with solid particles being retained by the filter screen 83. The water-fertilizer liquid then passes through the filter screen 83 into the lower side of the barrel 82 and is ultimately discharged through the outlet pipe 25.

[0036] The working principle of this integrated water and fertilizer sprinkler irrigation system is as follows: During actual use, external fertilizer is delivered to the fertilizer tank 3 via the material pump 2, where the fertilizer is temporarily stored. An appropriate amount of water is added to the water-fertilizer mixing tank 5 as needed. Simultaneously, the quantitative feeding blade 18 in the feeding tank 15 begins to rotate, driven by the servo motor 14. As the feeding blade rotates, it scoops up a certain amount of fertilizer and delivers it to the inlet of the feeding pipe 21. The fertilizer then enters the water-fertilizer mixing tank 5 through the feeding pipe 21 and mixes with the water in the tank. A one-way valve 16 mounted on the feeding pipe 21 ensures that fertilizer can only flow in one direction, preventing water vapor from rising into the feeding tank 15 and keeping the fertilizer dry. Next, the stirring motor 12 is started, which drives the stirring shaft 22 to rotate through its output terminal, causing the auger blade 23 on the stirring shaft 22 to rotate counterclockwise. This rotation method drives water and fertilizer upward, increasing the time the fertilizer floats in the water and ensuring that the fertilizer and water are fully mixed. In the water-fertilizer mixing tank 5, the counterclockwise rotation of the auger blade 23 not only drives the mixing of water and fertilizer, but also works together with the spoiler 24 fixed on the inner wall of the tank to generate additional disturbances, break up the agglomerates in the mixed liquid, and improve the mixing uniformity. After the mixing is completed, the water-fertilizer liquid is discharged through the liquid outlet pipe 25 at the bottom of the water-fertilizer mixing tank 5 and filtered through the filter cartridge 8. The filter screen plate 83 in the filter cartridge 8 intercepts solid particles in the liquid, preventing incompletely dissolved fertilizer from entering the diversion sprinkler pipe 11 and causing blockage. The filtered water-fertilizer liquid enters the booster pump 9 through the liquid inlet pipe 27. After the booster pump 9 increases the liquid pressure, it is transported to the sprinkler main 10. Finally, the right end of the sprinkler main 10 is connected to the diversion sprinkler pipe 11, and the water-fertilizer liquid is evenly sprayed onto the farmland, realizing the integrated water and fertilizer sprinkler operation.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
