The indicated device or element must have a particular orientation, a particular orientation and operation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1, as shown in the attached document Figures 1-5 As shown, this utility model provides a spraying water outlet structure, including a liquid tank 3 and a nozzle 4. A water pump 14 is fixedly installed at the bottom of the inner wall of the liquid tank 3. A suction pipe 16 is connected to the input end of the water pump 14, and a delivery pipe 15 is connected to the output end of the water pump 14. A protective box 30 is fixedly installed at the bottom of the liquid tank 3. The nozzle 4 is disposed inside the protective box 30. A connecting plate 5 is fixedly installed on one side of the outer wall of the nozzle 4. A motor 6 is fixedly installed at the top of the inner wall of the protective box 30. A drive screw 7 is fixedly installed at the output end of the motor 6, and the drive screw 7 is threadedly connected to a threaded hole on the connecting plate 5. The bottom end of the drive screw 7 is rotatably connected to the bottom end of the inner wall of the protective box 30 via a bearing. A gear 8 is fixedly sleeved on the outer wall of the drive screw 7. An outlet 9 is opened at the bottom end of the protective box 30. A sealing plate 10 covers the bottom of the outlet 9. A connecting shaft 12 passes through the bottom end of the protective box 30. One end of the sealing plate 10 is fixedly sleeved on the outer wall of the connecting shaft 12. A gear 11 is fixedly installed at the top end of the connecting shaft 12. The gear 11 meshes with the gear 8. A hose 13 is connected to the nozzle 4.

[0025] In the above technical solution, when the spraying operation is needed, the motor 6 can be started through remote control, the motor 6 drives the driving screw 7 to rotate, the driving screw 7 drives the connecting plate 5 to move downward, the connecting plate 5 drives the spray head 4 to move downward, the driving screw 7 also drives the gear 8 to rotate, the gear 8 drives the gear 11 to rotate, the gear 11 drives the connecting shaft 12 to rotate, and the connecting shaft 12 drives the sealing plate 10 to rotate. When the sealing plate 10 is rotated to no longer cover the outlet 9, the spray head 4 just extends from the outlet 9. At this time, the water pump 14 can be started to suck the liquid medicine in the liquid medicine tank 3 into the medicine suction pipe 16, and then the liquid medicine is transported to the spray head 4 through the medicine conveying pipe 15 and the hose 13, and finally sprayed out through the spray head 4 to spray the crops. When the spraying operation is completed, the motor 6 can be controlled to reverse rotation. At this time, the spray head 4 will be retracted into the liquid medicine tank 3, and the sealing plate 10 will seal the outlet 9 again, so that the protective box 30 can timely protect the spray head 4. When the spray head 4 is not used, dust or foreign matter is prevented from blocking the spray head 4, which affects the spraying efficiency of the spray head 4. Moreover, the existing plant protection unmanned aerial vehicle spraying structure generally adopts a detachable protective cover to protect the spray head 4. However, in actual application, frequent disassembly and assembly not only increase the operation difficulty, but also may cause additional damage to the spray head 4. Moreover, a single protective cover is easy to lose and inconvenient to use.

[0026] Further, the connecting plate 18 is fixedly installed on the other side of the outer wall of the spray head 4, the limiting rod 17 is fixedly installed on the inner wall of the protective box 30, the limiting rod 17 movably penetrates through the connecting plate 18, and the positioning groove 28 is formed in the top end of the liquid medicine tank 3.

[0027] The limiting rod 17 can limit the connecting plate 18, so that the stability of the spray head 4 during movement and use is ensured.
