Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery, and in particular relates to a drip irrigation device with a medicine spraying function. Background Art

[0002] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0003] Drip irrigation is currently the most effective water-saving irrigation method in arid and water-scarce regions, achieving a water utilization rate of up to 95%. Compared to sprinkler irrigation, drip irrigation offers greater water conservation and yield-increasing benefits. It can also be combined with fertilization to more than double fertilizer efficiency. It is suitable for irrigating fruit trees, vegetables, cash crops, and greenhouses. It can also be used to irrigate field crops in drought-scarce areas.

[0004] Currently, drip irrigation can only apply water and fertilizer downwards. In practice, there is a significant demand for foliar fertilizer and foliar spraying to combat insects. Foliar fertilizer and foliar spraying typically require the installation of separate spraying equipment, increasing investment costs. Furthermore, existing pesticide sprayers typically spray downwards, typically applying pesticide to the upper surface of leaves rather than the lower portion, which compromises their effectiveness. Summary of the Invention

[0005] To address the technical problems existing in the prior art, the present invention provides a drip irrigation device with a spraying function. This device utilizes a variable nozzle to adjust the water outlet flow rate, combined with pressure regulation at a booster station, to operate in both atomizing and dripping modes. This allows for watering to maintain soil moisture, fertilizing to strengthen seedlings, and spraying pesticides to kill insects. Combining drip irrigation with spraying pesticides allows for integrated water, fertilizer, and pesticide operations, reducing the workload of manual spraying. It also kills pests attached to the bottom of leaves, improving pesticide utilization, reducing pesticide usage, and enabling precise operation.

[0006] In order to solve the above technical problems, the technical solution of the present invention is:

[0007] A drip irrigation device with a spraying function, comprising: a pressure station, several adjustable nozzles and pipes,

[0008] The plurality of adjustable nozzles are installed on a pipeline, and the pipeline is connected to a pressurizing station;

[0009] The adjustable nozzle includes a water pipe, a nozzle pipe and a nozzle cap. The adjustable nozzle is installed on the pipeline through the water pipe. The nozzle pipe is installed on the water pipe and communicates with the inside of the water pipe.

[0010] The inner diameter of the nozzle tube is smaller than that of the water pipe. The end of the nozzle tube connected to the nozzle cap is processed into a tapered shape, and an external thread is processed on the side wall of the nozzle tube. The end where the nozzle cap is connected to the nozzle tube is a stepped cavity. The first-level cavity is conical and matches the tapered end of the nozzle tube. The inner wall of the second-level cavity is processed with an internal thread and matches the external thread.

[0011] A nozzle is arranged in the middle of the nozzle cap, and the nozzle is a flared structure.

[0012] The beneficial effects of the present invention are:

[0013] The adjustable nozzle is a key component of this invention. The outlet diameter is adjusted by rotating the nozzle cover. During spraying, the nozzle cover is rotated to reduce the cross-sectional area of ​​the nozzle outlet. A pressure station increases the water pressure in the pipeline, causing the atomized liquid to spray upward onto the underside of leaves, killing pests. During fertilization, the nozzle cover is rotated to increase the cross-sectional area of ​​the nozzle outlet. The pressure station reduces the water pressure in the pipeline, causing water or liquid fertilizer to flow out of the nozzle and into the soil, reducing evaporation and conserving water.

[0019] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] A drip irrigation device with a spraying function, comprising: a pressure station, several adjustable nozzles and pipes,

[0022] The plurality of adjustable nozzles are installed on a pipeline, and the pipeline is connected to a pressurizing station;

[0023] The adjustable nozzle includes a water pipe, a nozzle pipe and a nozzle cap. The adjustable nozzle is installed on the pipeline through the water pipe. The nozzle pipe is installed on the water pipe and communicates with the inside of the water pipe.

[0024] The inner diameter of the nozzle tube is smaller than that of the water pipe. The end of the nozzle tube connected to the nozzle cap is processed into a tapered shape, and an external thread is processed on the side wall of the nozzle tube. The end where the nozzle cap is connected to the nozzle tube is a stepped cavity. The first-level cavity is conical and matches the tapered end of the nozzle tube. The inner wall of the second-level cavity is processed with an internal thread and matches the external thread.

[0025] A nozzle is arranged in the middle of the nozzle cap, and the nozzle is a flared structure.

[0026] In some embodiments, the ratio of the inner diameter of the nozzle tube to the inner diameter of the water tube is 1:8-15.

[0027] The inner diameter of the nozzle tube is smaller than that of the water pipe. When the liquid flowing through the water pipe flows into the nozzle tube again, the flow area is reduced, the pressure increases, and the flow rate is accelerated. After flowing through the nozzle cap, the internal pressure of the liquid drops rapidly and the liquid is sprayed out in the form of mist.

[0028] In some embodiments, the ratio of the diameter of the small diameter end to the large diameter end of the nozzle is 1:1.5-3, so as to improve the atomization degree of the liquid.

[0029] In some embodiments, the ratio of the outer diameter to the inner diameter of the nozzle tube is 5-10:1.

[0030] Furthermore, the ratio of the length of the threaded connection section between the nozzle tube and the nozzle cap to the inner diameter of the nozzle tube is 2-10:1.

[0031] The outer diameter of the nozzle tube and the length of the threaded connection section are much larger than the inner diameter of the nozzle tube. When the nozzle cap is unscrewed outward, the cavity between the nozzle cap and the nozzle tube is sufficient to reduce the pressure and speed of the liquid sprayed from the nozzle tube, so that it is sprayed out in the form of a water column through the nozzle cap.

[0032] In some embodiments, a constricted flow guide structure is provided at the connection between the nozzle tube and the water pipe.

[0033] The constricted flow guide structure can allow the liquid in the water pipe to flow into the nozzle pipe more stably.

[0034] In some embodiments, the tapered structure at the end of the nozzle tube has the same shape and dimensions as the conical primary cavity of the nozzle cap. When the threaded connection between the nozzle tube and the nozzle cap is fully screwed in, the nozzle tube and the nozzle cap are in full contact, and liquid sprayed from the nozzle tube is directly ejected from the nozzle cap nozzle, which helps to improve the degree of atomization.

[0035] In some embodiments, the boosting station includes a water tank, a boosting pump and a valve. The inlet of the boosting pump is connected to the water tank through a pipeline, and the outlet of the boosting pump is connected to the pipeline, and the valve is provided on the pipeline.

[0036] Without adjusting the power of the booster pump, the liquid pressure in the pipeline can be adjusted by controlling the opening of the valve, thereby adjusting the spray state.

[0037] In some embodiments, the water pipe and the pipeline are connected via two-way pipes.

[0038] Example 1

[0039] like Figure 1 and Figure 2 As shown, filtered water / medicine solution is added to water tank 1-1 through water inlet 1-2. Water tank 1-1 is connected to booster pump 1-3 via pipe 1-4. Valve 1-5 is installed between the outlet of booster pump 1-3 and the drip irrigation system. Booster pump 1-3 is responsible for providing water pressure to the system. By adjusting the opening of valve 1-5, the pressure of the drip irrigation system can be changed without adjusting booster pump 1-3.

[0040] like Figure 3As shown, the adjustable nozzle comprises a nozzle cap 2-1, a nozzle tube 2-2, and a water tube 2-3. The nozzle cap 2-1 is secured to the nozzle tube 2-2 via threads. Both the nozzle cap 2-1 and the nozzle tube 2-2 have through-holes, allowing liquid to be ejected from the air. The nozzle tube 2-2 is secured to the water tube 2-3. The opening of the nozzle cap 2-1 is in the shape of an inverted cone. The interior of the nozzle tube 2-2 is hollow, and its inner diameter is much smaller than that of the water tube 2-3. This increases the pressure of the liquid within the nozzle tube 2-2. When the nozzle cap 2-1 is rotated and moved away from the nozzle tube, a cavity is formed between the nozzle cap 2-1 and the nozzle tube 2-2. The pressurized liquid in the nozzle tube 2-2 first enters this cavity, reducing the internal pressure of the liquid and causing it to gush out in the form of a liquid column, thereby achieving irrigation. Rotate the nozzle cap 2-1. When the nozzle cap 2-1 is close to the nozzle tube, the cavity between the nozzle cap 2-1 and the nozzle tube 2-2 is reduced. The liquid pressurized by the nozzle tube 2-2 will be sprayed out through the expanded opening of the nozzle cap 2-1. The internal pressure of the liquid is rapidly reduced, and the liquid is sprayed out in the form of mist, thereby realizing the spray operation.

[0041] The present invention provides three methods for adjusting the pressure of the liquid in the pipeline: first, controlling the speed of the booster pump to achieve water pressure regulation; second, adjusting valve 1-5 to adjust the internal pressure of pipeline 1-4; and third, adjusting nozzle cap 2-1 to adjust the water pressure at the outlet. These three methods can be used in combination according to actual conditions.

[0042] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
