[0006] The inner side end of the distribution branch pipe is provided with a fitting groove, and an inner magnetic ring is embedded and fittedly connected inside the fitting groove.

[0007] One side end of the outer magnetic ring is symmetrically provided with push rods, and the end of the push rod is rotatably connected with a rotating frame. The rotating frame is rotatably connected inside a rotating support. The end of the rotating frame is fixedly connected with a connecting frame, and a semi-circular shielding cover is connected at the end of the connecting frame in the liquid outlet direction of the irrigation nozzle.

[0017] 2. Through the fitting frame and filter screen embedded and connected in the feed hopper, filtration can be carried out during the process of adding water and fertilizer liquid and fertilizer into the water and fertilizer mixing tank, thus avoiding large particle solid impurities in the water and fertilizer additive, which may affect subsequent irrigation. At the same time, the driving shaft is used to synchronously drive the conical grinding head to rotate in the conical hopper. The conical hopper is arranged at the top of the water and fertilizer mixing tank. When the water and fertilizer additive is added to the water and fertilizer mixing tank, it needs to pass through the gap between the conical grinding head and the conical hopper. Through the rotation of the conical grinding head and the cooperation with the grinding strip, the water and fertilizer additive is ground, further avoiding solid particles in the water and fertilizer additive and preventing the irrigation nozzle from being blocked during subsequent water and fertilizer irrigation.

Specific embodiments

[0025] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0026] Embodiment: As Figures 1-4 shown, the present utility model provides a technical solution, a water and fertilizer integration irrigation device based on a crop growth model, including a water and fertilizer mixing tank 1. Feed hoppers 2 are symmetrically installed on both sides of the top of the water and fertilizer mixing tank 1. A control valve 3 is installed at the bottom of the feed hopper 2. A drive motor 4 is fixedly installed in the middle of the top end of the water and fertilizer mixing tank 1. The drive motor 4 is powered by an external power supply. The bottom of the output shaft of the drive motor 4 is connected to a drive shaft 5. Mixing blades 6 are symmetrically installed at equal intervals on the side of the drive shaft 5 at the inner side of the bottom of the water and fertilizer mixing tank 1. One side of the bottom of the water and fertilizer mixing tank 1 is connected to a main irrigation pipe 7. Distribution branch pipes 8 are connected to both sides of the main irrigation pipe 7 at equal intervals. A liquid guide pump is installed at the end of the main irrigation pipe 7 at the inner side of the water and fertilizer mixing tank 1. The main irrigation pipe 7 is fixed in the soil through a ground plug, which is convenient for transporting the mixed water and fertilizer, and ensures the stability of the main irrigation pipe 7 and the distribution branch pipes 8 during the irrigation process. The liquid outlet end of the end of the distribution branch pipe 8 is connected to an irrigation sprinkler 9;

[0027] A fitting groove 10 is opened at the inner side edge of the distribution branch pipe 8. An inner magnetic ring 11 is embedded and fitted in the inner side of the fitting groove 10. Return springs 12 are installed at equal angles on the side of the inner magnetic ring 11. An outer magnetic ring 13 is slidably connected to the corresponding position on the outside of the distribution branch pipe 8 opposite to the inner magnetic ring 11. Sliding guide bars are arranged along the circumferential direction on the outside of the distribution branch pipe 8. A sliding groove is opened on the inner side of the outer magnetic ring 13, and the sliding groove slides along the sliding guide bars, which is convenient for the outer magnetic ring 13 to move synchronously and stably along the inner magnetic ring 11. A limit ring 14 is fixedly installed at the position on the outside of the distribution branch pipe 8 corresponding to the length direction of the fitting groove 10;

[0028] On one side end of the outer magnetic ring 13, push rods 15 are symmetrically installed. Both the inner magnetic ring 11 and the outer magnetic ring 13 are strong magnetic blocks, and the inner magnetic ring 11 and the outer magnetic ring 13 are connected by magnetic adsorption. A through hole is provided inside the inner magnetic ring 11, and the diameter of the through hole is smaller than the inner diameter of the distribution branch pipe 8. Due to the strong magnetic adsorption between the outer magnetic ring 13 and the inner magnetic ring 11, the outer magnetic ring 13 pushes the push rod 15 to move during the movement process. One end of the push rod 15 is rotatably connected to a rotating frame 17, the rotating frame 17 is rotatably connected to the inside of a rotating support 16, one end of the rotating frame 17 is fixedly connected to a connecting frame 18, and at the end of the connecting frame 18 located in the liquid outlet direction of the irrigation nozzle 9, a semi-circular shielding cover 19 is connected. The rotating support 16 is fixedly connected to the side of the distribution branch pipe 8. The semi-circular shielding covers 19 at the ends of the two connecting frames 18 are combined to form a circular structure, and a rubber sleeve is bonded to the edge of the semi-circular shielding cover 19 to protect the irrigation nozzle 9, thereby preventing dirt in the environment from affecting the normal irrigation use of the irrigation nozzle 9.

[0029] A fitting frame 20 is embedded and fitted inside the feed hopper 2. A filter screen 21 is fixedly connected to the inner bottom end of the fitting frame 20. A conical hopper 22 is provided at the neck position of the water and fertilizer mixing tank 1. Grinding strips 23 are evenly arranged on the inner side edge of the conical hopper 22. A conical grinding head 24 is installed on the outer side of the drive shaft 5 at the inner position of the conical hopper 22. The conical grinding head 24 is in contact with the inner wall of the conical hopper 22, and the cross-sectional shapes of the conical grinding head 24 and the conical hopper 22 are the same. The top of the conical grinding head 24 is a circular convex structure with a high middle and a low edge. By the rotation of the conical grinding head 24 and in cooperation with the grinding strips 23, the water and fertilizer additive is ground, thereby further avoiding the existence of solid particles in the water and fertilizer additive.

[0030] The working principle and usage process of the present utility model: During the actual application process of this water and fertilizer integrated irrigation device based on the crop growth model, first, the water and fertilizer liquid and fertilizer are added into the water and fertilizer mixing tank 1 through the feed hopper 2. At this time, through the fitting frame 20 and the filter screen 21 embedded and connected in the feed hopper 2, filtration can be carried out during the process of adding the water and fertilizer liquid and fertilizer into the water and fertilizer mixing tank 1, thereby avoiding large particle solid impurities in the water and fertilizer additive, which may affect subsequent irrigation.

[0031] When the water and fertilizer additive is added to the water and fertilizer mixing tank 1, it needs to pass through the gap between the conical grinding heads 24 in the conical hopper 22. The driving motor 4 and the driving shaft 5 are used to drive the conical grinding heads 24 to rotate in the conical hopper 22. Since the conical grinding heads 24 and the conical hopper 22 are arranged at the top of the water and fertilizer mixing tank 1, during the process of adding the water and fertilizer additive to the water and fertilizer mixing tank 1, the water and fertilizer additive will flow to the edge of the conical grinding heads 24 and enter the gap between the conical grinding heads 24 in the conical hopper 22. Through the rotation of the conical grinding heads 24 and in cooperation with the grinding bars 23, the water and fertilizer additive is ground, further avoiding the existence of solid particles in the water and fertilizer additive and preventing the irrigation nozzles 9 from being blocked during subsequent water and fertilizer irrigation;

[0032] After the water and fertilizer additive is ground, it enters the water and fertilizer mixing tank 1. At this time, the driving motor 4 and the driving shaft 5 drive the mixing blades 6 to rotate synchronously, so that the water and fertilizer additive is mixed with water. Then, the mixed water and fertilizer is transported by the liquid delivery pump and the irrigation main pipe 7, and each distribution branch pipe 8 transports the water and fertilizer to the crops to be irrigated. The irrigation main pipe 7 and the distribution branch pipes 8 are fixed by ground plugs, ensuring the stability during the irrigation process;

[0033] When the water and fertilizer liquid flows through the distribution branch pipe 8, the fluid pressure of the water and fertilizer liquid drives the inner magnetic ring 11 to move, compressing the return spring 12. When the inner magnetic ring 11 moves, the outer magnetic ring 13 magnetically connected to the outside of the distribution branch pipe 8 will move accordingly. Due to the strong magnetic adsorption between the outer magnetic ring 13 and the inner magnetic ring 11, the outer magnetic ring 13 pushes the push rod 15 to move during the movement. At the same time, through the connection and rotation of the rotating support 16 and the rotating frame 17, when the push rod 15 is pushed, it drives the connecting frame 18 to turn over, so that the two semi-circular shielding covers 19 on the outer side of the end of the irrigation nozzle 9 are separated, enabling the irrigation nozzle 9 to perform normal spraying irrigation without affecting the normal irrigation use of the water and fertilizer;

[0034] After the water and fertilizer irrigation is completed, the fluid pressure of the water and fertilizer disappears. Using the reset function of the return spring 12, the inner magnetic ring 11 and the outer magnetic ring 13 are driven to move and reset, so that the connecting frame 18 and the semi-circular shielding cover 19 turn over towards each other, enabling the semi-circular shielding cover 19 to shield the outside of the irrigation nozzle 9, thus protecting the irrigation nozzle 9 and preventing dirt in the environment from affecting the normal irrigation use of the irrigation nozzle 9;

[0035] Moreover, LORA wireless technology is used for communication. With the decentralized control node as the execution device, the crop growth model establishes the relationship between the basic laws of crop growth and development and environmental factors, clarifies the response mechanism of crop regulation, quantifies the dynamic characteristics of crop growth, development, and yield and quality formation under different conditions, and finally implements automatic monitoring and automatic control during the crop growth process in the intelligent control device. The decentralized control method realizes the advantages of flexible networking, a system that can be large or small, low cost, and suitability for various terrains and plots, improving the utilization rate of natural resources, achieving the goals of low cost and high efficiency, increasing the yield and quality of crops, saving water resources, improving nutrient utilization rate, protecting the environment, and realizing sustainable development.

[0036] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features.
