Description

Technical Field

[0001] This utility model relates to the field of farmland irrigation technology, specifically to a water-powered integrated water and fertilizer machine. Background Technology

[0002] Integrated water and fertilizer technology refers to a new agricultural technology that integrates irrigation and fertilization. It utilizes a pressure system (or natural terrain gradient) to mix soluble solid or liquid fertilizers, tailored to soil nutrient content and crop requirements, with irrigation water via a pipeline system. After the water and fertilizer are combined, drip irrigation is achieved through pipes and emitters, evenly, regularly, and quantitatively irrigating the crop's root zone, ensuring the soil around the main root system remains loose and at an appropriate moisture content.

[0003] Hydrodynamic fertilizer applicators are an essential device in integrated water and fertilizer application. By reducing the opening angle of the valve on the main pipe, the water flow into the branch pipe can be increased. This utilizes the flow velocity of the irrigation water to generate the power to absorb fertilizer, drawing the fertilizer through a suction pipe into the main pipe to mix with the irrigation water, thus achieving water and fertilizer supply. However, existing hydrodynamic fertilizer applicators often experience vortices due to the different flow velocities and directions between the water in the branch pipe and the main pipe. Additionally, in some applications, excessive pressure in the pipes at the fertilizer inlet can prevent fertilizer from entering, thus affecting the fertilization effect. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a hydrodynamic fertilizer applicator that reduces the impact on fertilization effectiveness caused by excessive vortex and pressure preventing water and fertilizer from penetrating.

[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: a water-powered fertigation machine, comprising a main pipeline and a power fertilization component. The main pipeline is installed on the irrigation pipeline of farmland and is equipped with a diversion valve. The power fertilization component includes a branch pipe, a self-priming pump, and a water-powered worm gear. One end of the branch pipe is connected to the self-priming pump through a flange. The water-powered worm gear is installed inside the branch pipe. The other end and the inner side of the branch pipe are connected to the inner side of the main pipeline through a first connecting pipe and a second connecting pipe, respectively. A water-fertilizer inlet valve is provided on the first connecting pipe. The outlet end of the water-fertilizer inlet valve is connected to a bend pipe along the direction of water flow. The outlet end of the bend pipe is connected to a water-fertilizer pressure reducing pipe. The outlet end of the water-fertilizer pressure reducing pipe is located at one end of the water outlet in the main pipeline.

[0006] Furthermore, the second connecting pipe is equipped with a clean water outlet valve, and a clean water booster pipe is connected to the side of the outlet end of the clean water outlet valve facing the main pipeline.

[0007] Furthermore, the inlet end of the water and fertilizer inlet valve is connected to the outlet end of the self-priming pump via a water and fertilizer pipe.

[0008] Furthermore, the water outlet valve injects water into the bucket containing fertilizer through a water pipe at its outlet end, and the self-priming pump draws the fertilizer water out of the bucket through a suction pipe at its inlet end.

[0009] Furthermore, a filter element is connected to the inlet end of the water suction pipe.

[0010] Furthermore, the branch pipe is equipped with a flow display.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By adding a bend and a pressure reducing pipe inside the first connecting pipe, this utility model can avoid the problem of difficulty in mixing water and fertilizer with clean water due to differences in the flow direction and velocity of water in the pipe and excessive pressure inside the first connecting pipe, thus ensuring the mixing of water and fertilizer with clean water and improving the fertilization effect; by controlling the flow rate of diluted clean water injected into the water tank through the clean water outlet valve, the flow rate of diluted clean water can be increased in conjunction with the clean water pressure boosting pipe, thereby improving the dilution effect.

[0017] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-4As shown, this utility model provides a water-powered fertigation machine, including a main pipeline 1 and a power fertilization component. The main pipeline 1 is installed on the pipeline for irrigating farmland and is equipped with a diversion valve 2. The power fertilization component includes a branch pipe 3, a self-priming pump 4, and a water-powered worm gear 5. One end of the branch pipe 3 is connected to the self-priming pump 4 through a flange 6. The flange 6 allows for easy disassembly, facilitating later maintenance and repair. The water-powered worm gear 5 is installed inside the branch pipe 3. The other end and the inner side of the branch pipe 3 are connected to the inner side of the main pipeline 1 through a first connecting pipe 7 and a second connecting pipe 8, respectively. The first connecting pipe 7 is equipped with a water-fertilizer inlet valve 9. The outlet end of the water-fertilizer inlet valve 9 is fixedly connected to a bend pipe 17 along the direction of water flow. The outlet end of the bend pipe 17 is fixedly connected to a water-fertilizer pressure reducing pipe 10, and the outlet end of the water-fertilizer pressure reducing pipe 10 is located at one end of the water outlet in the main pipeline 1.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the diversion valve 2 is located between the first connecting pipe 7 and the second connecting pipe 8. The opening angle of the diversion valve 2 increases the water flow rate into the branch pipe 3, thereby utilizing the flow velocity of the irrigation water to generate the power to absorb fertilizer, drawing the water and fertilizer into the main pipe 1 to mix with the irrigation water, thus achieving water and fertilizer supply. The larger the opening of the diversion valve 2, the smaller the impact on the hydrodynamic worm gear 5, and vice versa, thus adjusting the working efficiency of the fertilizer applicator. The hydrodynamic worm gear 5 is connected to the input end of the self-priming pump 4 via a rotating shaft. The rotation of the hydrodynamic worm gear 5 drives the rotating shaft to rotate, and the rotating shaft drives the self-priming pump 4 to work. Figure 1 As shown, the water flow velocity and direction in the first connecting pipe 7 and the main pipe 1 are different, which will generate vortices. The presence of vortices will make it difficult to inject water and fertilizer into the first connecting pipe 7. Moreover, when the pressure in the first connecting pipe 7 exceeds 3 kg, it will also cause difficulties in injecting water and fertilizer. Therefore, in this embodiment, these problems can be avoided by adding a bend pipe 17 and a water and fertilizer pressure reducing pipe 10. Specifically, water and fertilizer enter the bend pipe 17 and the water and fertilizer pressure reducing pipe 10 in sequence through the water and fertilizer inlet valve 9, and enter the outlet end of the main pipe 1 along the water and fertilizer pressure reducing pipe 10 and mix with the clean water in the main pipe 1. By changing the flow direction of water and fertilizer and the mixing position of water and fertilizer with clean water, the problem of difficulty in injecting water and fertilizer due to vortices in the first connecting pipe 7 or excessive pressure is avoided.

[0020] The second connecting pipe 8 is equipped with a clean water outlet valve 11, and a clean water booster pipe 12 is connected to the side of the outlet end of the clean water outlet valve 11 facing the main pipeline 1.

[0021] like Figure 4As shown, the function of the clean water outlet valve 11 is to control the flow rate of diluted clean water injected into the water tank. When the flow divider valve 2 is adjusted to reduce the impact on the hydraulic worm gear 5, the flow rate in the second connecting pipe 8 decreases, which reduces the water pressure in the second connecting pipe 8. As a result, clean water cannot flow out during the dilution of fertilizer. Therefore, in this embodiment, a clean water booster pipe 12 is added so that the inlet of the clean water booster pipe 12 faces the direction of the water flow in the second connecting pipe 8, thereby increasing the pressure at the inlet of the clean water booster pipe 12 and increasing the flow rate of diluted clean water.

[0022] The inlet end of the water and fertilizer inlet valve 9 is connected to the outlet end of the self-priming pump 4 via the water and fertilizer pipe 13.

[0023] like Figure 1 As shown, the self-priming pump 4 draws in diluted water and fertilizer, which then enters the water and fertilizer pressure reducing pipe 10 through the water and fertilizer pipe 13.

[0024] The water outlet valve 11 injects water into the water tank containing fertilizer through the water pipe 14, and the inlet of the self-priming pump 4 sucks out the fertilizer water from the water tank through the suction pipe 15.

[0025] like Figure 1 As shown, the clean water in the second connecting pipe 8 is injected into the water bucket through the clean water pipe 14, and mixed with the fertilizer in the water bucket to dilute it.

[0026] A filter element 16 is connected to the inlet end of the water suction pipe 15.

[0027] like Figure 1 As shown, the filter element 16 includes a filter screen and a filter box. The inlet end of the suction pipe 15 passes through the filter screen and is inserted into the filter box to filter impurities or undissolved fertilizer, ensuring that the water and fertilizer sucked into the self-priming pump 4 are free of large particles, thus improving the service life of the self-priming pump 4.

[0028] The branch pipe 3 is equipped with a flow display 18.

[0029] like Figure 1 As shown, the flow display 18 displays the rotation speed, fertilizer application rate, pressure, and water pump flow rate through the rotation of the hydro-powered turbine 4, making it convenient for staff to view and control the opening and closing degree of the diversion valve 2 based on the displayed data.

[0030] Operating principle: Before using the device, check for any issues that might affect its use. When the operator needs to use the device, first open the diversion valve 2, the water-fertilizer inlet valve 9, and the clean water outlet valve 11 to allow water to flow in the main pipeline 1. Under water pressure, the water in pipeline 1 flows along the second connecting pipe 8 into the branch pipe 3. As the water flows into the branch pipe 3, the water in the second connecting pipe 8 flows through the clean water booster pipe 12 into the clean water pipe 14, diluting the fertilizer in the bucket. When the second connecting pipe 8 enters the branch pipe 3, the water flow impacts the hydraulic worm gear 5, causing it to rotate. Under the action of the rotating shaft, the self-priming pump 4 is activated. When the self-priming pump 4 is working, it draws the diluted water-fertilizer from the bucket through the suction pipe 15 and flows along the water-fertilizer pipe 13 into the water-fertilizer pressure reducing pipe 10. The water then flows along the water-fertilizer pressure reducing pipe 10 towards the outlet of the main pipeline 1 and mixes with the clean water in the main pipeline 1, achieving integrated irrigation and fertilization.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
