[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Reference Figures 1-7 This utility model provides an embodiment of a dripper for precision drip irrigation and fertilization, comprising a first outer shell 1, a second outer shell 2 fixedly connected to the lower surface of the first outer shell 1, a connecting column 3 rotatably connected to the inner wall of the second outer shell 2, a turntable 4 fixedly connected to the top of the connecting column 3, a support plate 5 provided on the outer wall of the connecting column 3, the outer wall of the support plate 5 slidably connected to the inner wall of the second outer shell 2, a card 6 fixedly connected to the upper surface of the support plate 5, a fixing block 7 provided on the outer wall of the card 6, a gear 8 fixedly connected to the bottom end of the connecting column 3, a rack 9 meshing with the outer wall of the gear 8, the outer wall of the rack 9 fixedly connected to the inner wall of the fixing block 7, a base plate 10 fixedly connected to the bottom end of the fixing block 7, the outer wall of the base plate 10 slidably connected to the lower inner wall of the second outer shell 2, and a filter assembly provided on the upper inner wall of the first outer shell 1 for filtering impurities in the water; the filter assembly includes a first guide plate 12, the outer wall of the first guide plate 12 fixedly connected to the upper inner wall of the first outer shell 1, and a filter screen 13 fixedly connected to the lower inner wall of the first outer shell 1.

[0028] Specifically, the first outer shell 1 is used to fix the first guide plate 12, the turntable 4 is used to drive the connecting column 3 to rotate, and at the same time, it is used to fix the connecting column 3. The connecting column 3 is used to fix the gear 8. The gear 8 is used to drive the fixing block 7 to move up and down. The filter screen 13 is used to filter impurities inside the water and fertilizer.

[0029] Reference Figures 4-5 A stop block 11 is fixedly connected to the outer wall of the connecting column 3; the outer wall of the stop block 11 is rotatably connected to the outer wall of the support plate 5; a second guide plate 14 is fixedly connected to the inner wall of the first outer shell 1; a connecting hole 15 is opened on the inner wall of the second outer shell 2; a drip nozzle 16 is fixedly connected to the outer wall of the connecting hole 15; a third guide plate 17 is fixedly connected to the upper inner wall of the second outer shell 2.

[0030] Specifically, the second outer shell 2 is used to fix the third guide plate 17. The second guide plate 14 and the third guide plate 17 are used to prevent backflow of water and fertilizer during use and to reduce the flow rate of water and fertilizer. The nozzle 16 is used to spray water and fertilizer.

[0031] Working principle: When the device is used, the water and fertilizer first pass through the inner wall of the first outer shell 1. The first guide plate 12 guides the water and fertilizer in a primary manner. When passing through the filter screen 13, other impurities in the water and fertilizer are filtered to prevent them from clogging the connection hole 15 and the drip nozzle 16. When the water and fertilizer pass through the second guide plate 14, they undergo a secondary guide. When passing through the third guide plate 17, they undergo a tertiary guide. Finally, the water and fertilizer are sprayed out through the connection hole 15 and the drip nozzle 16. This achieves the goal of guiding the forward-flowing water to flow along a specific direction of the guide plate. When the water flows back, the guide plate will prevent the backflowing water from returning along the original path, thus preventing backflow. By rotating and pulling the turntable 4, when the turntable 4 rotates, it will drive the connecting column 3 to rotate on the inner wall of the second outer shell 2. At the same time, the connecting column 3 will drive the support plate 5 to slide on the inner wall of the second outer shell 2 due to the action of the stop block 11. Rotating the connecting column 3 drives the gear 8 to rotate, which in turn drives the rack 9 to move up and down. The rack 9's movement up and down causes the fixing block 7 to move up and down, which in turn causes the base plate 10 to move up and down, thus fixing the fixing block 7. By pushing the turntable 4, the turntable 4 will slide due to the stop block 11. The sliding of the support plate 5 will cause the outer wall of the turntable 4 to be stuck on the inner wall of the fixing block 7, finally fixing the base plate 10. This allows for precise adjustment of the drip flow rate according to different crop growth stages, soil types, and climatic conditions. The drip nozzle of this integrated water and fertilizer precision drip irrigation system can not only guide the forward-flowing water to flow along a specific direction of the guide plate, but also prevent the backflowing water from returning along its original path when the water flows back, thus preventing backflow. It can also precisely adjust the drip flow rate according to different crop growth stages, soil types, and climatic conditions.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
