Abstract
Description
Technical Field
[0001] This utility model relates to the field of irrigation equipment technology, and in particular to a dripper structure for water-saving irrigation. Background Technology
[0002] Irrigation drippers are the core components of drip irrigation systems. Their structure typically includes a flow channel system that generates frictional resistance through complex flow channels such as labyrinths and orifices to control the flow rate. They achieve precise water-saving irrigation by dispensing water in small droplets, which is more water-saving than traditional irrigation. At the same time, localized irrigation reduces soil compaction and crop diseases. They are widely used in arid regions and high-efficiency agricultural scenarios such as vegetables and fruit trees, and are a key technology carrier for achieving precise water saving, quality improvement and yield increase.
[0003] However, in the existing technology, the dripper structure cannot automatically adjust the pipe diameter based on water pressure, which means that the water flow rate cannot be automatically adjusted according to the inlet water pressure. When the inlet water pressure is high, the water flow rate is too high, resulting in a waste of water resources. When the inlet water pressure is low, the water flow rate is too low, resulting in reduced irrigation efficiency and even insufficient irrigation. Utility Model Content
[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a dripper structure for water-saving irrigation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dripper structure for water-saving irrigation, comprising a water outlet pipe, a connector fixedly connected to the side of the water outlet pipe, an inlet pipe fixedly connected to the end of the connector, an installation pipe fixedly connected to the upper part of the water outlet pipe, a connecting frame installed inside the installation pipe, a spring fixedly connected to the bottom of the connecting frame, an adjusting plug fixedly connected to the bottom of the spring, the adjusting plug being slidably connected to the inner wall of the water outlet pipe, and the adjusting plug being located above the end of the connector; a connecting pipe fixedly connected to the upper part of the inlet pipe, the end of the connecting pipe being fixedly connected to the side of the water outlet pipe, and the connecting pipe being located above the adjusting plug.
[0006] Preferably, a nut is fixedly connected to the upper part of the mounting tube, and an adjusting screw is threaded onto the surface of the nut. The bottom of the adjusting screw is rotatably connected to the connecting frame.
[0007] Preferably, a limiting rod is fixedly connected to the bottom of the connecting frame, and a limiting tube is fixedly connected to the bottom of the adjusting plug. The limiting rod is inserted into the adjusting plug and the limiting tube respectively.
[0008] Preferably, a cleaning needle is fixedly connected to the bottom of the limiting tube, and the cleaning needle is located at the center of the water outlet.
[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0010] 1. In this utility model, the automatic adjustment of the water flow rate with the inlet water pressure is achieved through the linkage design of the inlet pipe, connecting pipe, adjusting plug and spring. When the inlet water pressure is high, the connecting pipe transmits the water pressure to the upper part of the adjusting plug, pushing the adjusting plug to compress the spring and move downward, reducing the water inlet area of the connector and the outlet pipe, and avoiding excessive water flow and water waste. When the inlet water pressure is low, the spring resets and drives the adjusting plug to move upward, increasing the water inlet area, and preventing the water flow from being too small, which would reduce irrigation efficiency or cause insufficient irrigation. This structure does not require external power and automatically adjusts the flow rate by relying on the dynamic balance of water pressure and spring force. It effectively solves the problems of insufficient water saving and uneven irrigation caused by the inability of traditional drippers to adapt to water pressure fluctuations, improves the stability and applicability of the drip irrigation system under different water pressure environments, and has the technical advantages of water saving and efficiency improvement and precise irrigation.
[0011] 2. In this utility model, the insertion and cooperation of the limiting rod and the limiting tube ensures that the adjusting plug slides stably along the inner wall of the water outlet when it moves up and down, avoiding the deviation of flow regulation caused by shaking. When the adjusting plug moves, it drives the cleaning needle at the bottom of the limiting tube to move synchronously. When the water pressure changes and drives the adjusting plug to move down, the cleaning needle can penetrate into the center of the water outlet head to actively unclog it, effectively reducing the risk of clogging of the water outlet head by mud and impurities.
[0012] 3. In this utility model, the initial height of the connecting frame is changed by rotating the adjusting screw, thereby adjusting the starting position of the adjusting plug in the water outlet pipe. This adapts to the initial flow requirements of different irrigation scenarios, significantly improving the applicability of the dripper under different crop and soil conditions. This design integrates flow regulation, anti-clogging maintenance, and personalized parameter settings, taking into account system stability, anti-clogging capability, and usage flexibility.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Example 1: As Figures 1-4 As shown, this utility model provides a water-saving irrigation dripper structure, including a water outlet pipe 1, a connector 2 fixedly connected to the side of the water outlet pipe 1, a water inlet pipe 3 fixedly connected to the end of the connector 2, an installation pipe 6 fixedly connected to the upper part of the water outlet pipe 1, a connecting frame 9 installed inside the installation pipe 6, a spring 10 fixedly connected to the bottom of the connecting frame 9, an adjusting plug 11 fixedly connected to the bottom of the spring 10, the adjusting plug 11 is slidably connected to the inner wall of the water outlet pipe 1, and the adjusting plug 11 is located above the end of the connector 2; a connecting pipe 4 is fixedly connected to the upper part of the water inlet pipe 3, the end of the connecting pipe 4 is fixedly connected to the side of the water outlet pipe 1, and the connecting pipe 4 is located above the adjusting plug 11.
[0021] The specific settings and functions of this embodiment are described below. Water is supplied to the connector 2 and the outlet pipe 1 through the inlet pipe 3, and irrigation is carried out through the outlet head 5. Water enters the upper part of the regulating plug 11 through the connecting pipe 4. When the water pressure increases, the connecting pipe 4 generates greater pressure on the upper part of the regulating plug 11. At this time, the spring 10 extends, and the regulating plug 11 moves downward, reducing the water inlet area of the connector 2 into the outlet pipe 1, thereby reducing the water output. When the water pressure is low, the spring 10 returns to its original deformation, pulling the regulating plug 11 upward along the inner wall of the outlet pipe 1, thereby increasing the water inlet area of the connector 2 into the outlet pipe 1. Thus, the water output can be automatically adjusted according to the water pressure.
[0022] Through the linkage design of the inlet pipe 3, connecting pipe 4, regulating plug 11, and spring 10, the water flow rate is automatically adjusted according to the inlet water pressure: when the inlet water pressure is high, the connecting pipe 4 transmits the water pressure to the upper part of the regulating plug 11, pushing the regulating plug 11 to compress the spring 10 and move downward, reducing the inlet area of the connector 2 and the outlet pipe 1, and avoiding excessive water flow that would waste water resources; when the inlet water pressure is low, the spring 10 resets and drives the regulating plug 11 to move upward, increasing the inlet area, and preventing the water flow rate from being too low, which would reduce irrigation efficiency or cause insufficient irrigation. This structure does not require external power and automatically adjusts the flow rate by relying on the dynamic balance between water pressure and the elasticity of the spring 10. It effectively solves the problems of insufficient water saving and uneven irrigation caused by the inability of traditional drippers to adapt to water pressure fluctuations, improves the stability and applicability of the drip irrigation system under different water pressure environments, and has the technical advantages of water saving and efficiency improvement as well as precision irrigation.
[0023] Example 2: Figure 3 and Figure 4 As shown, a nut 7 is fixedly connected to the upper part of the installation pipe 6. An adjusting screw 8 is threadedly connected to the surface of the nut 7. The bottom of the adjusting screw 8 is rotatably connected to the connecting frame 9. A limit rod 14 is fixedly connected to the bottom of the connecting frame 9. A limit tube 12 is fixedly connected to the bottom of the adjusting plug 11. The limit rod 14 is inserted into the adjusting plug 11 and the limit tube 12 respectively. A cleaning needle 13 is fixedly connected to the bottom of the limit tube 12. The cleaning needle 13 is located at the center of the water outlet head 5.
[0024] The overall effect of this embodiment is that when the adjusting plug 11 moves up and down inside the water outlet pipe 1, the limiting tube 12 slides along the limiting rod 14, improving the stability of the adjusting plug 11 during movement. When the adjusting plug 11 moves downward, it can also push the limiting tube 12 and the cleaning needle 13 downward, thereby clearing the water outlet 5 through the cleaning needle 13 and reducing the risk of the water outlet 5 being blocked. In the initial use stage, the initial height of the connecting bracket 9 inside the installation pipe 6 can be adjusted by rotating the adjusting screw 8, thereby adjusting the initial height of the adjusting plug 11 inside the water outlet pipe 1 and improving the overall applicability.
[0025] The insertion and engagement of the limiting rod 14 and the limiting tube 12 ensures that the regulating plug 11 slides stably along the inner wall of the outlet pipe 1 when moving up and down, avoiding flow regulation deviations caused by shaking. When the regulating plug 11 moves, it drives the cleaning needle 13 at the bottom of the limiting tube 12 to move synchronously. When the water pressure changes and drives the regulating plug 11 to move down, the cleaning needle 13 can penetrate deep into the center of the outlet head 5 to actively unclog it, effectively reducing the risk of clogging of the outlet head 5 by silt and impurities. During initial use, the initial height of the connecting bracket 9 can be changed by rotating the adjusting screw 8, thereby adjusting the starting position of the regulating plug 11 in the outlet pipe 1 to adapt to the initial flow requirements of different irrigation scenarios, significantly improving the applicability of the dripper under different crop and soil conditions. This design integrates flow regulation, anti-clogging maintenance, and personalized parameter settings, taking into account system stability, anti-clogging ability, and usage flexibility.
[0026] The device is used and works as follows: Water is supplied to the connector 2 and the outlet pipe 1 through the inlet pipe 3, and irrigation is carried out through the outlet head 5. Water enters the upper part of the regulating plug 11 through the connecting pipe 4. When the water pressure increases, the connecting pipe 4 exerts greater pressure on the upper part of the regulating plug 11. At this time, the spring 10 extends, and the regulating plug 11 moves downward, reducing the water inlet area of the connector 2 into the outlet pipe 1, thereby reducing the water output. When the water pressure is low, the spring 10 returns to its original shape, pulling the regulating plug 11 upward along the inner wall of the outlet pipe 1, thereby increasing the water inlet area of the connector 2 into the outlet pipe 1. Thus, the water output can be automatically adjusted according to the water pressure.
[0027] When the regulating plug 11 moves up and down inside the water outlet pipe 1, the limiting tube 12 slides along the limiting rod 14 to improve the stability of the regulating plug 11 when it moves. When the regulating plug 11 moves down, the regulating plug 11 can also push the limiting tube 12 and the cleaning needle 13 to move down. The cleaning needle 13 can be used to clear the water outlet 5 and reduce the risk of the water outlet 5 being blocked.
[0028] During the initial use phase, the initial height of the connecting bracket 9 inside the mounting pipe 6 can be adjusted by rotating the adjusting screw 8, thereby adjusting the initial height of the adjusting plug 11 inside the water outlet pipe 1 and improving the overall applicability.
[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
