Description

Technical Field

[0001] The utility model belongs to the technical field of water-fertilizer integration, and particularly relates to a mixing device for a water-fertilizer integration irrigation system. Background Art

[0002] Integrated fertigation (IFR) is a new agricultural technology that integrates irrigation and fertilization. Using a pressure system (or natural terrain drop), IFR 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 controllable piping system. Once the fertilizer and water are combined, drip irrigation flows through pipes and drippers, evenly, regularly, and quantitatively irrigating the root development and growth areas of the crops, ensuring the soil around the root system remains loose and at an appropriate moisture content. IFR also designs the fertilizer solutions for different vegetable growth stages based on their specific fertilizer requirements, soil environment, nutrient content, and water and fertilizer needs during their respective growth periods. This ensures that water and nutrients are delivered directly to the crops in a timely, quantitative, and proportional manner.

[0003] For example, Chinese utility model patent CN201721397696.1 discloses an integrated water and fertilizer irrigation system, comprising a main water supply pipeline, branch pipelines, a fertilizer suction device, and an integrated water and fertilizer control system. The fertilizer suction device includes a venturi tube, a mixed fertilizer tank, a branch pipeline check valve, etc.; the integrated water and fertilizer control system includes an electric flow control valve, an electromagnetic flowmeter, a pH sensor, an EC sensor, and a programmable logic controller. This intelligent integrated water and fertilizer control system automatically adjusts the opening of the electric flow control valve based on the detected pH / EC value and the fertilizer concentration requirements of different crops, as well as the flow rate in the main water supply pipeline measured by the electromagnetic flowmeter. This changes the amount of fertilizer sucked into the venturi tube, thereby controlling the fertilizer concentration near the required level and achieving precise, intelligent, and automated water and fertilizer management.

[0004] The above-mentioned irrigation system uses a venturi tube to suck in fertilizer to mix water and fertilizer, forming a water-fertilizer mixed solution of a certain concentration. It can be seen that this irrigation system is only suitable for liquid fertilizers or easily soluble powdered fertilizers with fine particles. It cannot quickly dissolve and mix large-particle solid fertilizers, and there is a risk of clogging the irrigation system. Utility Model Content

[0005] The purpose of the utility model is to provide a fertilizer-water mixing device for a water-fertilizer integrated irrigation system to solve the disadvantage that the existing water-fertilizer integrated irrigation system is not suitable for large-particle insoluble solid fertilizers and to improve the practicality of the irrigation system.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A fertilizer-water mixing device for a water-fertilizer integrated irrigation system comprises a mixing box, a solid material delivery port and a water inlet pipe being provided on the top of the mixing box, a water outlet pipe being provided at the bottom, a stirring shaft being transversely provided inside the mixing box, a plurality of stirring blades being evenly provided on the stirring shaft, one end of the stirring shaft extending out of the mixing box and being transmission-connected to a motor fixed on the side wall of the mixing box; a liquid adding box is also fixed to the bottom of one side of the mixing box, a liquid pump is fixed to the top of the liquid adding box, the liquid inlet and liquid outlet ends of the liquid pump are both connected to a pipette, and the two ends of the pipette are respectively fixed to the liquid adding box and the bottom inside the mixing box.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] First, water is added to the mixing box through the top water inlet pipe. The glass window with scale on the mixing box can intuitively show the volume of water in the mixing box. Then, a certain mass of solid fertilizer particles is added according to the water-fertilizer ratio, and the motor is started to drive the stirring shaft to stir and mix. After stirring and mixing evenly, it can be discharged through the water outlet pipe, which solves the disadvantages of existing irrigation systems that are not suitable for solid fertilizers and the concentration of water-fertilizer solution is uncontrollable. In addition, since some liquid fertilizers or pesticides need to be diluted in advance before being mixed with water-fertilizer solution for application, a liquid adding tank is fixedly set next to the mixing box, and a liquid pump is used to mix the diluted fertilizer liquid or liquid medicine with the water-fertilizer solution in the mixing box, which solves the disadvantages of manual multiple dilution and liquid addition. At the same time, the setting of the liquid adding tank can dissolve fertilizers (or liquid medicines) separately according to type, batch, and sequence, so that the solid fertilizer in the mixing box is dissolved and mixed evenly with other fertilizer (or pesticide) solutions. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural diagram of the present utility model.

[0011] In the figure, 1-mixing box, 2-liquid adding box, 3-pipette, 4-liquid pump, 5-motor, 6-stirring shaft, 7-stirring blade, 8-solid material feeding port, 9-water inlet pipe, 10-water outlet pipe, 11-universal wheel, 12-hydraulic support rod, 13-support pad, 14-observation window, 15-transparent viewing block. DETAILED DESCRIPTION

[0012] The present invention will be further explained below with reference to the accompanying drawings.

[0013] like Figure 1As shown, a fertilizer-water mixing device for a water-fertilizer integrated irrigation system includes a mixing box 1, a solid material feeding port 8 and a water inlet pipe 9 are provided on the top of the mixing box 1, a water outlet pipe 10 is provided at the bottom, and valves are installed on the water inlet pipe 9 and the water outlet pipe 10; a stirring shaft 6 is provided inside the mixing box 1 for horizontal rotation, and a plurality of stirring blades 7 are evenly provided on the stirring shaft 6, and one end of the stirring shaft 6 extends out of the mixing box 1 and is transmission-connected to a motor 5 fixed on the side wall of the mixing box 1; a liquid adding box 2 is also fixed to the bottom of one side of the mixing box 1, a liquid pump 4 is fixed to the top of the liquid adding box 2, and the liquid inlet and liquid outlet ends of the liquid pump 4 are connected to a pipette 3, and the two ends of the pipette 3 are respectively fixed to the liquid adding box 2 and the bottom inside the mixing box 1; a long strip-shaped observation window 14 is provided on the front of the mixing box 1, and a transparent viewing block 15 with scale lines is installed on the observation window 14.

[0014] During use, the valve on the water inlet pipe 9 is opened to add a certain volume of water to the mixing box 1. Then, according to the calculated water-fertilizer ratio, a certain amount of solid fertilizer is added from the solid material inlet 8. The motor 5 is started to rotate the stirring shaft 6 and the stirring blade 7, thereby achieving water-fertilizer mixing. During mixing, the current solution volume and the degree of fertilizer dissolution can be visually viewed using a transparent sight block 15 with scale lines installed on the observation window 14, thereby determining when to shut down the motor 5. Because some liquid fertilizers or pesticides need to be diluted before mixing with the water-fertilizer solution for application, a liquid adding tank 2 is fixedly installed next to the mixing box 1. A liquid pump is used to mix the diluted fertilizer or liquid medicine in the liquid adding tank 2 with the water-fertilizer solution in the mixing box 1. This solves the drawbacks of manual multiple dilution and liquid addition, and achieves separate dissolution and mixing of different types, batches, and in a sequential order.

[0015] It can be seen from the above working process that the fertilizer-water mixing device of the utility model not only solves the disadvantage that the existing water-fertilizer integrated irrigation system is not suitable for large-particle solid fertilizer particles, but also adds a drug mixing function to ensure that water, fertilizer and drugs are mixed evenly, and has made due contributions to the promotion of water-fertilizer integrated technology.

[0016] Compared with the existing water-fertilizer integrated irrigation system that mixes water and fertilizer in the pipe, the fertilizer-water mixing device of the utility model, which mixes water and fertilizer in advance, also has the following advantages:

[0017] 1. Uniform fertilization: Mixing water and fertilizer evenly in advance can ensure uniform fertilization and avoid excessive or insufficient fertilizer in some areas, thereby improving fertilizer utilization and crop growth.

[0018] ‌2. Reduce clogging‌: If fertilizers are not mixed evenly, it may cause clogging of the drip irrigation system, affecting the irrigation effect; by auxiliary stirring, ensuring that the fertilizers dissolve quickly in water, the clogging problem can be reduced;

[0019] ‌3. Improve fertilizer absorption efficiency‌: By mixing water and fertilizer in advance, you can ensure that the fertilizer is evenly distributed during the irrigation process, and the crop roots can absorb nutrients more effectively, thereby improving fertilizer absorption efficiency.

[0020] Furthermore, to enhance the environmental adaptability of the fertilizer-water mixing device, universal wheels 11 and hydraulic support rods 12 are mounted at the four corners of the bottom of the mixing box 1. Each hydraulic support rod 12 has a support pad 13 fixed to its end. During operation, the fertilizer-water mixing device can be rolled into a field and connected to the rest of the irrigation system. The hydraulic support rods 12 support the entire mixing box, ensuring stability during operation. After use, the hydraulic support rods can be lowered and the mixing box 1 can be moved indoors to protect it from wind and rain, extending the device's overall service life.
