[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] like Figures 1 to 8 As shown, an agricultural spraying device is provided, including a mobile vehicle 1 and a spraying water pipe 6. A plastic film sleeve 5 is fitted on the outside of the spraying water pipe 6. A blowing structure is provided at one end of the plastic film sleeve 5, and a leak-proof sealing structure is provided at the other end of the spraying water pipe 6 and the plastic film sleeve 5. A spraying structure connected to the spraying water pipe 6 is installed on the surface of the plastic film sleeve 5. Air outlets 11 are evenly opened on the surface of the plastic film sleeve 5. The distance between two adjacent spray heads 13 is one meter, and the distance between two adjacent air outlets 11 is three meters. In this embodiment, the blowing structure blows air onto the plastic film sleeve 5, filling it with air and causing it to float. The spray pipe 6 floats along with the plastic film sleeve 5. The user pulls one end of the plastic film sleeve 5 and the spray pipe 6, causing the spray pipe 6 to float in the air, preventing it from pressing on the plants. The spray pipe 6, floating in the air, sprays out the liquid inside through the spraying structure, making it easy to spray the surrounding plants. This not only facilitates the movement of the pipe but also prevents it from affecting the growth of the plants. With the help of the air outlet 11, the continuous blowing of air onto the plastic film sleeve 5 is prevented from causing it to burst and affecting its use.

[0019] like Figures 1 to 3As shown, an agricultural spraying device is provided. A take-up roller 4 is rotatably mounted on the upper end of a mobile vehicle 1. One end of the take-up roller 4 is inserted into a plastic film sleeve 5 and a spray water pipe 6 and extends out from the adjacent side. The blowing structure includes a connecting air cylinder 9 and a fixed water pipe 10. The connecting air cylinder 9 is fixedly mounted on the upper end of the mobile vehicle 1. The fixed water pipe 10 passes through the interior of the connecting air cylinder 9 and is rotatably connected to the spray water pipe 6. The plastic film sleeve 5 is rotatably connected to the connecting air cylinder 9. A blower 2 and a water pump 3 are mounted on the upper end of the mobile vehicle 1. The blower 2 and the water pump 3 are respectively connected to one end of the fixed water pipe 10 and the connecting air cylinder 9. In this embodiment, the blower 2 continuously supplies airflow into the plastic film sleeve 5 through the connecting air cylinder 9. Under the action of stable wind force, the plastic film sleeve 5 is kept in a suspended state. At the same time, the water pump 3 starts to operate, pressurizing the liquid medium to be sprayed into the spray pipe 6 and spraying it evenly through the nozzle at its end, so as to achieve precise spraying of crops. The fixed water pipe 10 and the spray pipe 6 adopt a rotatable connection structure, and the plastic film sleeve 5 and the connecting air cylinder 9 also adopt a rotatable connection. This design effectively avoids interference with the normal blowing and suspension function and liquid spraying function when the take-up roller 4 performs the take-up operation on the plastic film sleeve 5 and the spray pipe 6, thereby ensuring that the system can maintain a stable and efficient working state during operation and take-up. Moreover, the setting of the take-up roller 4 not only effectively improves the flexibility and adaptability of the overall structure, but also significantly enhances the turnover efficiency and portability of the equipment. This design cleverly optimizes the workflow, making the entire system smoother and more efficient in operation, while greatly simplifying the steps of moving and transporting, providing users with great convenience.

[0020] The entire device can be moved to different locations for reuse via the mobile vehicle 1. The user pulls the traction handle 7 at one end, causing the plastic film sleeve 5 and the spray pipe 6 wound on the surface of the take-up roller 4 to unfold. The length of the plastic film sleeve 5 and the spray pipe 6 can be 30 meters, 50 meters, etc., and can be set to different lengths as needed. When the plastic film sleeve 5 and the spray pipe 6 are completely unfolded from the surface of the take-up roller 4, the blower 2 blows air. When the blower 2 continuously delivers air to the plastic film sleeve 5 through the air cylinder 9, the air is discharged downward from the air outlet 11, which generates a corresponding back force, causing the plastic film sleeve 5 to carry the spray pipe 6 and float in the air in parallel. At this time, the water pump 3 starts to work, and under the action of water pressure, the fan-shaped nozzles on the pipe 6 begin to spray. In order to prevent the absence of blind spots when each nozzle is working, each nozzle is about one meter apart, which facilitates the spraying of surrounding crops and plants. This not only facilitates the movement of the water pipe, but also prevents it from affecting the growth of crops.

[0021] like Figure 7 and Figure 8As shown, an agricultural spraying device is provided. The sealing structure includes a sealing jacket 8, which is sleeved on the outside of a plastic film sleeve 5 and one end of a spray pipe 6. A traction handle 7 is detachably installed on one side of the sealing jacket 8, and a sealing cap is installed on one end of the spray pipe 6 near the sealing jacket 8. In this embodiment, the sealing sleeve 8 ensures that one end of the plastic film sleeve 5 is tightly clamped to the surface of the spray pipe 6, preventing air leakage from the plastic film sleeve 5 and affecting its floating. This ensures the stability and safety of the entire spraying device during operation. The design of the traction handle 7 makes it easier and faster for operators to install and remove the sealing sleeve 8. The operation can be easily completed by simply pulling the handle 7, and it is also convenient for users to pull the plastic film sleeve 5 and the spray pipe 6 to move, making it easy to adjust the spraying position and improving work efficiency. The sealing cap further enhances the sealing effect at the end of the spray pipe 6, preventing liquid leakage from the end during spraying, thus avoiding waste and environmental pollution. Its unique suspension design allows the spray pipe 6 to float in the air, avoiding pressure on crops and protecting the crop growth environment. At the same time, the precise spraying function allows the liquid medium to be sprayed evenly on the crops, improving the spraying effect and reducing waste. In addition, the device is easy to operate and move, making it easier and more comfortable for users to use.

[0022] like Figure 5 and Figure 6 As shown, an agricultural spraying device is provided. The spraying structure includes a connecting sleeve 12, which is disposed on the surface of a spraying water pipe 6. A spraying head 13 is installed on one side of a plastic film sleeve 5. An insertion tube 14 is provided at one end of the spraying head 13. The insertion tube 14 passes through the plastic film sleeve 5 and is inserted into the interior of the connecting sleeve 12 to connect with the spraying water pipe 6. A sealing ring 15 is detachably installed at one end of the interior of the spraying head 13. A spraying plate 16 is installed on one side of the sealing ring 15. A fixing cap 17 is detachably installed on the surface of the spraying head 13 by means of threads. The distance between two adjacent spraying heads 13 is one meter. In this embodiment, when the device is started for spraying, the connecting sleeve 12 is securely fitted onto the surface of the spray pipe 6, providing a stable connection base for the spray head 13. The insert 14 is precisely inserted through the plastic film sleeve 5 into the connecting sleeve 12, tightly connected to the spray pipe 6, ensuring that the liquid can flow smoothly from the spray pipe 6 into the spray head 13. The sealing ring 15 is tightly installed at one end inside the spray head 13, effectively preventing liquid leakage and ensuring the sealing of the spraying operation. The spray blade 16 is selected and installed according to different spraying needs. Its unique structural design allows the liquid to be sprayed out in a specific shape and range, meeting diverse agricultural spraying requirements. The fixing cap 17 is detachably installed on the surface of the spray head 13 by threads, which not only facilitates the inspection and replacement of the internal parts of the spray head 13, but also further fixes the spray blade 16, ensuring that it will not loosen during operation. A distance of one meter is maintained between two adjacent spray heads 13. This layout can ensure uniform coverage of the spraying range, avoid spraying dead spots, and improve the efficiency and quality of agricultural spraying.

[0023] like Figure 7 and Figure 8 As shown, an agricultural spraying device is provided. A connecting component is provided between the sealing jacket 8 and the traction handle 7. The connecting component includes an installation groove, which is opened inside the traction handle 7. An insertion port is opened on one side of the installation groove. The sealing jacket 8 is composed of two semi-circular rings rotatably connected. Both ends of the sealing jacket 8 are provided with insertion blocks 18. The two insertion blocks 18 fit together. One end of the two insertion blocks 18 passes through the insertion port and is movably inserted into the inside of the installation groove. A locking spring 19 is provided inside the insertion block 18. A movable locking block 20 is fixedly installed on one end of the locking spring 19. One end of the movable locking block 20 is movably inserted into the outside of the insertion block 18. One side of the movable locking block 20 fits against the inner wall of the installation groove. One end of the movable locking block 20 is inclined. In this embodiment, the sealing jacket 8 covers one end of the plastic film sleeve 5 and the spray pipe 6, sealing one end of the plastic film sleeve 5. The two inserts 18 at one end of the sealing jacket 8 fit together and are inserted into the socket. During the insertion process, the movable locking block 20 is squeezed by the inner wall of the mounting groove and retracts into the insert 18, while compressing the locking spring 19. When the movable locking block 20 moves into the mounting groove, the locking spring 19 returns to its original deformation, popping the movable locking block 20 out. One end of the movable locking block 20 fits against the inner wall of the mounting groove, thus firmly fixing the sealing jacket 8 to the traction handle 7, ensuring the sealing effect of the sealing jacket 8 on one end of the plastic film sleeve 5, preventing air leakage during use, ensuring the normal operation of the entire device, and this connection component is simple and ingeniously designed, making installation and disassembly very convenient.

[0024] like Figure 7 and Figure 8As shown, an agricultural spraying device is provided. A support spring 22 is installed on one side of the mounting groove. A movable plate 21 is fixedly installed on one end of the support spring 22. A reset sleeve 25 that cooperates with the insert block 18 is provided on one side of the movable plate 21. A movable rod 23 is installed on one side of the movable plate 21. One end of the movable rod 23 is movably inserted through the outside of the traction handle 7 and is equipped with a connecting strip 24. In this embodiment, when it is necessary to remove the sealing sleeve 8 from the traction handle 7, simply push the connecting bar 24. The connecting bar 24 drives the movable rod 23 to move into the mounting groove. The movable rod 23 then drives the moving plate 21 to stretch the support spring 22. The moving plate 21 moves so that the reset sleeve 25 is fitted onto the surface of the insert 18, and the movable locking block 20 is pressed into the interior of the insert 18. At this time, the user can pull the insert 18 out of the socket with a little force, smoothly disengaging it from the mounting groove, thereby achieving quick separation of the sealing sleeve 8 from the traction handle 7. This design is convenient for maintenance or replacement. When replacing the sealing jacket 8 and other related components, it can greatly save operation time and improve work efficiency. At the same time, when the moving plate 21 is not subjected to external force, the support spring 22 will push the moving plate 21 to reset the reset sleeve 25, so that the sealing jacket 8 can be accurately matched with the insert block 18 when it is installed next time, ensuring the stability and reliability of the connection assembly. The entire connection assembly, through the synergistic effect between the components, not only ensures the firmness of the connection between the sealing jacket 8 and the traction handle 7, but also realizes the convenience of disassembly, providing a strong guarantee for the normal use and maintenance of agricultural spraying devices.
