[0029] Different types of plants require different flow rates for drip irrigation. The flow rates in existing drip irrigation devices are mostly fixed and cannot be adjusted, resulting in a small application range of the drip irrigation devices.

[0030] In view of this, the utility model provides a water-saving drip irrigation device, such as Figures 1 to 5As shown, it includes a water tank 1, a water pump 2 and a drip irrigation pipe 3; the water tank 1 is used to store water; the water pump 2 is used to provide water delivery power; the drip irrigation pipe 3 has a plurality of water outlets 31 and a water inlet, the water inlet is connected to one end of the water pump 2, and the other end of the water pump 2 is connected to the water tank 1, each of the water outlets 31 is provided with a drip irrigation member 4, the drip irrigation member 4 includes a connecting portion 41 and a drip irrigation head 42, one end of the connecting portion 41 is inserted into the water outlet 31, and the drip irrigation head 42 is movably connected to the other end of the connecting portion 41; wherein the connecting portion 41 is provided with a first channel 411, and the drip irrigation head 42 is provided with a second channel 421, and the drip irrigation member 4 has a first water outlet state in which the first channel 411 is aligned with the second channel 421, and a second water outlet state in which the drip irrigation head 42 moves relative to the connecting portion 41 along the length direction of the drip irrigation pipe 3, and the first channel 411 is partially aligned with the second channel 421.

[0031] In an optional embodiment, if Figure 2 As shown, the drip irrigation member 4 also includes a guide rail 43, a slider 44 and a linkage rod 45. The guide rail 43 is connected to the end of the connection portion 41 away from the drip irrigation pipe 3. The guide rail 43 is provided with a guide groove 431. One end of the slider 44 is movably connected to the guide groove 431. The slider 44 is arranged on one side of the drip irrigation head 42. The linkage rod 45 is used to connect the adjacent drip irrigation heads 42 or the slider 44. When the linkage rod 45 is pulled, the slider 44 moves along the guide groove 431, and all the drip irrigation heads 42 move along the length direction of the drip irrigation pipe 3.

[0032] Furthermore, the linkage rod 45 may also be a retractable structure formed by connecting a plurality of rod bodies, so that the retractable linkage rod 45 can be adapted to the drip irrigation pipes 3 with different intervals of the water outlet holes 31 .

[0033] In an optional embodiment, if Figure 2 As shown, baffles 46 are provided at both ends of the guide rail 43, and the baffles 46 are used to limit the range of motion of the drip irrigation head 42. Specifically, when the linkage rod 45 is pushed, the slider 44 contacts the baffle 46, indicating that the outlet of the first channel 411 is completely aligned with the inlet of the second channel 421, and the flow rate of the drip irrigation head 42 is the largest. When the drip irrigation head 42 contacts the baffle 46 relative to one side of the slider 44, it means that the outlet of the first channel 411 is partially aligned with the inlet of the second channel 421, and the flow rate of the drip irrigation head 42 is the smallest.

[0034] Further, such as Figure 1 and Figure 3As shown, a bracket is provided near one side of the water tank 1, and a fixing plate 7; bracket; 71 is provided corresponding to the bracket, and a latch hole is provided on the fixing plate 7; bracket; 71, and a linkage rod 45 near the bracket is provided with a plurality of fastening holes, and the linkage rod 45 is penetrated through the fixing plate 7; bracket; 71. After the linkage rod 45 is pulled to adjust the appropriate water flow rate, the latch hole and the fastening hole are manually adjusted to correspond, and after alignment, the fixing plate 7; bracket; 71 is connected to the linkage rod 45 through the latch 8 to maintain the drip irrigation component 4 for long-term drip irrigation at this flow rate.

[0035] In an optional embodiment, if Figure 2 As shown, the baffle 46 is provided with a limiting hole 461, and the linkage rod 45 is passed through the limiting hole 461 and connected to the slider 44 or the drip irrigation head 42. The linkage rod 45 and the slider 44 and the drip irrigation head 42 may be connected by threaded connection or by welding, and both methods can ensure the connection stability between the linkage rod 45 and the slider 44 and the drip irrigation head 42. Further, the two ends of the linkage rod 45 are respectively connected to the drip irrigation head 42 and the slider 44 of the adjacent drip irrigation member 4, so that when the linkage rod 45 is pulled to move in the length direction of the drip irrigation pipe 3, multiple drip irrigation heads 42 move in the same direction at the same time, thereby realizing the flow regulation of multiple drip irrigation members 4.

[0036] In an optional embodiment, if Figure 4 and Figure 5 As shown, the end of the drip irrigation head 42 facing the connecting portion 41 is provided with a sealing gasket 5. The provision of the sealing gasket 5 can ensure that after the drip irrigation head 42 moves, the gap between the connecting portion 41 and the drip irrigation head 42 is always filled with the sealing gasket 5, so as to maintain the sealing effect between the drip irrigation head 42 and the connecting portion 41 before and after the movement.

[0037] In an optional embodiment, the connection portion 41 has an insertion end 412 inserted into the drip irrigation pipe 3, and a guide surface 413 is provided around the insertion end 412. The slope of the guide surface 413 facilitates the connection portion 41 to be quickly inserted into the drip irrigation pipe 3. After the insertion end 412 is inserted into the drip irrigation pipe 3, the surrounding side of the connection portion 41 fits with the edge of the water outlet 31.

[0038] In an optional embodiment, if Figure 4 and Figure 5As shown, the peripheral side of the connection part 41 is provided with a sealing sleeve 6, and the sealing sleeve 6 is located between the connection part 41 and the drip irrigation pipe 3. By setting the sealing sleeve 6, the sealing performance between the connection part 41 and the drip irrigation pipe 3 can be improved, and water can be prevented from flowing out from the gap between the two. Specifically, a limiting card groove 414 is provided on the peripheral side of the connection part 41, and the sealing sleeve 6 is sleeved in the limiting card groove 414, and is tightly fitted with the limiting card groove 414 through the material properties of the sealing sleeve 6 itself. At the same time, the diameter of the limiting card groove 414 is smaller than the side of the insertion end 412 close to the sealing sleeve 6, so that after the insertion end 412 is inserted into the drip irrigation pipe 3, the edge of the water outlet 31 is inserted into the limiting card groove 414, which further improves the connection strength and stability between the connection part 41 and the drip irrigation pipe 3.

[0039] In an optional embodiment, if Figure 4 and Figure 5 As shown, the second channel 421 is in a serpentine structure. The second channel 421 is in a serpentine design, which is beneficial to water buffering.

[0040] Avoid excessive water flow rate and ensure smooth water outflow. In addition, the second channel 421 can also be a spiral design.

[0041] In summary, by moving the position of the drip irrigation head 42, the second channel 421 is aligned or staggered with the first channel 411 of the connecting part 41, so that the flow rate from the first channel 411 to the second channel 421 is changed, and the flow rate at the outlet of the second channel 421 is further adjusted to meet the needs of plants with different water requirements. At the same time, drip irrigation can directly drip water or nutrients to the roots of the plants, saving water resources; and the linkage rod 45 is used to achieve simultaneous adjustment of multiple drip irrigation heads 42, thereby improving the work efficiency of the staff.
