[0002] Irrigation is an indispensable and crucial aspect of agricultural planting, directly affecting crop growth, yield, and quality. Proper irrigation provides crops with the necessary water to meet their growth and development needs, promotes nutrient absorption by roots, and enhances photosynthetic efficiency, thereby increasing yield and improving quality. Especially in water-scarce regions, scientific and efficient irrigation techniques are key to achieving sustainable agricultural development.

[0003] Many current automated irrigation systems employ a uniform irrigation strategy, providing uniform irrigation to the entire irrigated area. However, in actual production, there are often significant differences in soil moisture, crop type, and growth stage among different plots in the fields. When only a particular plot is short of water or a certain crop requires a specific amount of irrigation, existing automated irrigation systems struggle to achieve precise, plot-specific irrigation.

[0004] In agricultural planting, crops need to be supplemented with fertilizers and pesticides for both the roots and leaves. However, in existing technologies, the fertilizer and pesticide supplementation devices for crop roots and leaves are often independent of each other. This not only increases the cost and complexity of the equipment, but may also affect the quality of crops. Utility Model Content

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] like Figure 1 As shown, a water-saving irrigation system that can be switched manually and automatically includes a water and fertilizer device, a drip irrigation device, and a sprinkler irrigation device. The water and fertilizer device is connected to the drip irrigation device and the sprinkler irrigation device through pipes respectively. The drip irrigation device and the sprinkler irrigation device are set at intervals. The drip irrigation device is equipped with a detector 19. The drip irrigation device and the sprinkler irrigation device work together and can be flexibly switched according to the needs of crop planting, which significantly improves the utilization rate of the water-saving irrigation system.

[0027] As a preferred embodiment of this utility model, the water and fertilizer device includes a water storage tank 2, a fertilizer storage tank 1, and a mixing tank 3. Both the water storage tank 2 and the fertilizer storage tank 1 are provided with an inlet I4 and an outlet I6. The outlet I6 is connected to the mixing tank 3 through a pipe. A filter 5 and a pump 8 are provided at the inlet I4, and a valve 7 is installed at the outlet I6. The mixing tank 3 is provided with an inlet II24 and an outlet II25. A pump 8 is provided at both the inlet II24 and the outlet II25, and a filter 5 is provided at the outlet II25.

[0028] In a preferred embodiment of the present invention, a detector 19 is provided inside the mixing tank 3; both the fertilizer storage tank 1 and the mixing tank 3 are provided with a drain outlet 20.

[0029] Fertilizer storage tank 1 is equipped with a water inlet I4 to flush the inside of the tank and prevent fertilizer residue, so that it can be used for irrigation with a different fertilizer. By adjusting valve 7 and turning on pump 8, fertilizer storage tank 1 and water storage tank 2 respectively deliver fertilizer and water to mixing tank 3, where fertilizer is mixed. Detector 19 in mixing tank 3 can detect the fertilizer ratio. When fertilizer or pesticide needs to be replaced, wastewater in mixing tank 3 and fertilizer storage tank 1 can be discharged from drain outlet 20 respectively.

[0030] like Figure 2 The mixing tank 3 shown has an opening 26 on top, and the mixing tank 3 has a mixing tank cover 9 that matches the opening 26. The mixing tank cover 9 has a through hole (not shown in the figure, the rest are the same); a stirrer 16 is provided through the through hole.

[0031] In a preferred embodiment of the present invention, the transmission rod 17 of the stirrer 16 passes through the through hole, and two fixing blocks 18 are provided on the transmission rod 17 at the corresponding position below the mixing tank cover 9; a lifting cylinder 15 is fixed on the outer wall of the mixing tank 3, and the lifting cylinder 15 lifts the stirrer 16.

[0032] When more than one type of fertilizer is needed for irrigation, different fertilizers can be added through the opening 26 on top of the mixing tank 3. When crops need a certain pesticide, the valve 7 at the outlet I6 of the fertilizer storage tank can be closed, and the required pesticide can be added through the opening 26 on top of the mixing tank 3. The water storage tank 2 delivers water to the mixing tank 3 for pesticide dilution. The stirrer 16 can accelerate the mixing process and make the liquid in the tank more uniform. The fixing block 18 on the transmission rod 17 can fix the mixing tank cover 9. When the lifting cylinder 15 lifts the stirrer 16, the mixing tank cover 9 can be opened to add fertilizer or pesticide and observe the situation inside the tank.

[0033] In a preferred embodiment of the present invention, the sprinkler irrigation device is mounted above the drip irrigation device via a support pad 14; the sprinkler irrigation device and the drip irrigation device are respectively connected to the mixing tank 3 via pipes, and valves 7 are provided at the connection points.

[0034] The sprinkler irrigation device avoids physical interference with the drip irrigation device by setting up a support pad 14, thus saving space; the operation of the sprinkler irrigation device and the drip irrigation device can be controlled by adjusting the valve 7.

[0035] like Figure 1 and Figure 3 As shown, the drip irrigation device includes several drip irrigation pipes 10, all of which are connected to the pipeline; several drip irrigation heads 11 are evenly connected upwards to the drip irrigation pipes 10, and anti-clogging covers 21 are fitted on the drip irrigation heads 11; valves 7 are provided at the connection points between the drip irrigation pipes 10 and the pipeline.

[0036] The drip head 11 is positioned upwards to prevent it from directly contacting the ground and to avoid backflow of soil and other impurities that could cause pipe blockage when the drip irrigation device is not in operation. The anti-clogging cover 21 on the drip head 11 can prevent blades and other debris from falling onto the drip head 11 and causing pipe blockage. The valve 7 at the connection between the drip irrigation pipe 10 and the pipeline can control each drip irrigation pipe 10 for segmented irrigation.

[0037] In a preferred embodiment of this utility model, a detector 19 is provided on the drip irrigation pipe 10; one end of the detector 19 is fixed on the drip irrigation pipe 10, and the other end is inserted into the soil to detect the soil, thereby realizing block detection.

[0038] like Figure 1 and Figure 4 As shown, the sprinkler irrigation device includes several sprinkler pipes 12, all of which are connected to pipelines; the sprinkler pipes 12 are connected to several spray pipes 22 perpendicular to the sprinkler pipes 12, the spray pipes 22 are connected to the nozzles 13, and the spray pipes 22 are supported by support rods 23; the support rods 23 can fix the spray pipes 22 to prevent the spray pipes 22 from swaying when the water pressure is too high.

[0039] The working principle of this utility model is as follows:

[0040] Fertilizer tank 1 is used to store fertilizer, and water tank 2 is used to store water. Open the valve 7 at the outlet I6 of both fertilizer tank 1 and water tank 2, and start the corresponding pump 8. Fertilizer and water are transported together through pipeline to mixing tank 3 for mixing. If the crops need pesticides or other fertilizers, the lifting cylinder 15 lifts the agitator 16, and the mixing tank cover 9 is lifted together with the agitator 16. At this time, the required pesticides or fertilizers are added to the opening 26 of mixing tank 3. The agitator 16 in mixing tank 3 accelerates the mixing process, and the detector 19 in mixing tank 3 constantly detects the concentration of the liquid in the tank.

[0041] When drip irrigation is needed, open the valve 7 corresponding to the drip irrigation device and start the corresponding pump 8. The pump 8 will deliver the prepared liquid to the corresponding connected pipe of the drip irrigation device. If full drip irrigation is needed, open all valves 7 corresponding to the drip irrigation pipe 10. If segmented drip irrigation is needed, open the valve 7 corresponding to the drip irrigation pipe 10.

[0042] When sprinkler irrigation is needed, open the valve 7 corresponding to the sprinkler device, start the corresponding machine 8, and the pump 8 will deliver the prepared liquid to the corresponding connected pipe of the sprinkler device, and the sprinkler device will start working.

[0043] When only pure water irrigation is needed, close valve 7 corresponding to fertilizer storage tank 1. Water flows from water storage tank 2 through the corresponding pump 8 to mixing tank 3. At this time, agitator 16 does not work. At this time, open valve 7 corresponding to drip irrigation device and start the corresponding pump 8 to start drip irrigation. When only a certain area is short of water, open valve 7 corresponding to drip irrigation pipe 10 to carry out block drip irrigation.

[0044] The above description is merely a preferred embodiment of this utility model. However, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, are all covered within the protection scope of this utility model.
