Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and more specifically, to a spraying module for a drone. Background Technology

[0002] A drone spraying module refers to a specialized equipment system used by drones to spray pesticides, fertilizers, or other liquid substances. This module typically consists of nozzles, pumps, liquid tanks, and a control system, enabling precise and uniform spraying. Through efficient airflow and positioning technology, drone spraying modules can achieve precise control from high altitudes, significantly improving the efficiency and effectiveness of agricultural spraying, reducing labor costs, and decreasing the amount of pesticides and fertilizers used, thus promoting sustainable agriculture. With technological advancements, these modules can also be combined with sensor and data analysis systems to achieve precision agriculture management.

[0003] However, different pesticides have different physical properties (such as viscosity, volatility, etc.), and different crops, pests and diseases and application targets have different requirements for droplet size. Therefore, using the right nozzle can not only optimize the spraying effect and achieve better coverage and adhesion, but also control the size of the spray particles to meet specific application needs.

[0004] Existing drone spraying modules adopt an integrated design, with the nozzle tightly integrated with other components (such as pumps and liquid tanks). While this design improves overall stability and portability, it also makes disassembling and replacing the nozzle more complicated, thus affecting the efficiency of pesticide spraying. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a spraying module for drones to solve the problem that the disassembly and replacement of the nozzles of the spraying modules of drones in the existing technology are relatively complicated, which affects the efficiency of pesticide spraying.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a spraying module for a drone, including a drone body, a plurality of mounting brackets fixedly connected to the bottom of the drone body, a transfer pipe fixedly connected to the opposite side of the mounting brackets, a symmetrically arranged fixing bracket fixedly connected to the top of the transfer pipe, a liquid tank fixedly connected to the top of the fixing bracket, a water pump fixedly connected to the outer wall of the liquid tank, the liquid tank being connected to the interior of the transfer pipe through the water pump, a plurality of nozzles for spraying pesticides being provided at the bottom of the transfer pipe, and a connecting mechanism for connecting the nozzles and the transfer pipe being provided between the two.

[0007] The connecting mechanism includes multiple connecting tubes, which are uniformly and fixedly connected to the bottom of the transfer tube, and the interior of the connecting tube is in communication with the interior of the transfer tube. The top of each nozzle is fixedly connected to a connecting seat that is in communication with its interior. The top of the connecting seat extends upward to form a plug-in portion. A sealing element is fixedly connected inside the connecting tube. A snap-fit ​​assembly for snapping the two together is provided between the connecting tube and the connecting seat.

[0008] The snap-fit ​​assembly includes multiple U-shaped guide grooves, which are evenly distributed on the outer wall of the connector. A snap-fit ​​groove is formed by the bend in the middle of the guide groove. Multiple snap-fit ​​plates are fixedly connected to the outer wall of the connector tube. A snap-fit ​​post is fixedly connected to the inner wall of the snap-fit ​​plate. The snap-fit ​​post can be inserted into the guide groove and snap-fit ​​with the snap-fit ​​groove.

[0009] Preferably, the inner wall of the seal gradually extends towards the center to form multiple annular structures, which are used to form a fitting portion that fits against the outer wall of the insertion portion.

[0010] Preferably, the top openings of the guide grooves are inclined to both sides, and the inclined top openings of the guide grooves form a guide channel for guiding the card post, and the guide channel gradually narrows from the top inner radial direction to the bottom.

[0011] Preferably, a plurality of springs are fixedly connected to the bottom of the connecting tube, and a stop ring is fixedly connected to the other end of the spring. The bottom of the stop ring abuts against the top of the connecting seat under the elastic force of the spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model comprises a drone body, mounting frame, transfer pipe, fixing frame, liquid tank, water pump, nozzle, and connecting mechanism. The water pump draws pesticide from the liquid tank, which enters the transfer pipe and then passes through the connecting pipe and connecting seat to the nozzle for spraying. When the nozzle needs to be disassembled and replaced, the nozzle is pushed down and rotated to release the connecting seat, allowing for quick disassembly of the nozzle. Similarly, when replacing a new nozzle, the connecting seat on the new nozzle is inserted into the connecting pipe and rotated to fix the nozzle in place. This enables quick disassembly and replacement of the nozzle, increasing pesticide spraying efficiency.

[0014] 2. In this utility model, the insertion part formed on the connector and the connecting pipe are sealed by a sealing element. The multiple annular structures formed in the middle of the sealing element cause the insertion part to push against the sealing part when the insertion part is inserted into the connecting pipe, so that the sealing part bends and fits between the insertion part and the sealing element. In this way, the sealing part seals the connecting pipe and the insertion part at multiple points, increases the sealing effect, and prevents pesticide leakage. Attached Figure Description

[0021] like Figures 1 to 4 As shown, this utility model relates to a spraying module for a drone, including a drone body 1. Multiple mounting brackets 2 are fixedly connected to the bottom of the drone body 1. A transfer pipe 3 is fixedly connected to one of the opposite sides of the mounting brackets 2. A symmetrically arranged fixing bracket 4 is fixedly connected to the top of the transfer pipe 3. A liquid tank 5 is fixedly connected to the top of the fixing bracket 4. A water pump 6 is fixedly connected to the outer wall of the liquid tank 5. The liquid tank 5 is connected to the interior of the transfer pipe 3 through the water pump 6. Multiple nozzles 7 for spraying pesticides are provided at the bottom of the transfer pipe 3. A connecting mechanism for connecting the nozzles 7 and the transfer pipe 3 is provided between the nozzles 7 and the transfer pipe 3.

[0022] The connecting mechanism includes multiple connecting pipes 8, which are uniformly and fixedly connected to the bottom of the transfer pipe 3, and the interior of the connecting pipe 8 is connected to the interior of the transfer pipe 3. The top of each nozzle 7 is fixedly connected to a connecting seat 9 that is connected to its interior. The top of the connecting seat 9 extends upward to form a plug-in part 10. A sealing element 11 is fixedly connected inside the connecting pipe 8. A snap-fit ​​assembly for snapping the two together is provided between the connecting pipe 8 and the connecting seat 9.

[0023] The snap-fit ​​assembly includes multiple U-shaped guide grooves 12, which are evenly opened on the outer wall of the connector 9. The middle bend of the guide groove 12 forms a snap-fit ​​groove 13. Multiple snap-fit ​​plates 14 are fixedly connected to the outer wall of the connector 8. Snap-fit ​​posts 15 are fixedly connected to the inner wall of the snap-fit ​​plates 14. The snap-fit ​​posts 15 can be inserted into the guide grooves 12 and snap-fit ​​with the snap-fit ​​grooves 13.

[0024] Specifically, align the connector 9 on the nozzle 7 with the connecting pipe 8, so that the locking post 15 is aligned with the opening of the guide groove 12. Then push the nozzle 7 upward so that the insertion part 10 is inserted into the connecting pipe 8. The sealing element 11 seals the insertion part 10 and the connecting pipe 8. At this time, the locking post 15 on the locking plate 14 will also enter the guide groove 12. Then rotate the nozzle 7 so that the nozzle 7 rotates and drives the connector 9 to rotate, so that the locking post 15 is in the slot 13. At this time, stop pushing the nozzle 7 and let the nozzle 7 fall under its own weight, so that the slot 13 locks the locking post 15, thus completing the fixation of the connector 9. During the flight of the drone body 1, the water pump 6 draws pesticide from the liquid tank 5, so that the pesticide enters the transfer pipe 3, and then enters the nozzle 7 through the connecting pipe 8 and the connector 9 to spray out, thus completing the spraying of pesticide.

[0025] Similarly, when it is necessary to disassemble the nozzle 7, push the nozzle 7 so that the slot 13 no longer jams the pin 15. Then rotate the nozzle 7 to pull it out, thus completing the quick disassembly of the nozzle 7.

[0026] Furthermore, the inner wall of the seal 11 gradually extends towards the center to form multiple annular structures, which are used to form a fitting portion 16 that fits against the outer wall of the insertion portion 10.

[0027] Specifically, the insertion part 10 formed on the connector 9 and the connecting pipe 8 are sealed by the sealing member 11. The multiple annular structures of the fitting part 16 formed in the middle of the sealing member 11 cause the insertion part 10 to push the fitting part 16 when it is inserted into the connecting pipe 8, so that the fitting part 16 bends and fits between the insertion part 10 and the sealing member 11. In this way, the fitting part 16 provides multi-point sealing between the connecting pipe 8 and the insertion part 10, increases the sealing effect, and prevents pesticide leakage.

[0028] Furthermore, the top opening of the guide groove 12 is inclined to both sides, and the inclined top opening of the guide groove 12 forms a guide channel for guiding the locking post 15, and the top inner radial diameter of the guide channel gradually narrows to the bottom.

[0029] Specifically, the guide channel formed at the opening of the guide groove 12 guides the pin 15 when it is inserted into the guide groove 12, increasing the smoothness and convenience of the pin 15 entering the guide groove 12.

[0030] Furthermore, a plurality of springs 17 are fixedly connected to the bottom of the connecting tube 8, and a retaining ring 18 is fixedly connected to the other end of the spring 17. The bottom of the retaining ring 18 abuts against the top of the connecting seat 9 under the elastic force of the spring 17.

[0031] Specifically, the spring 17 presses against the retaining ring 18, causing the retaining ring 18 to push against the connecting seat 9 under the elastic force of the spring 17. The slot 13 is pressed against the retaining post 15 by the pushing force of the spring 17, thereby increasing the stability of the connection between the connecting seat 9 and the connecting tube 8.

[0032] Working principle: This embodiment provides a spraying module for a drone. In use, the connecting seat 9 on the nozzle 7 is aligned with the connecting pipe 8, so that the locking post 15 is aligned with the opening of the guide groove 12. At this time, the nozzle 7 is pushed upward so that the insertion part 10 is inserted into the connecting pipe 8. The sealing part 11 seals the insertion part 10 and the connecting pipe 8. At this time, the locking post 15 on the locking plate 14 will also enter the guide groove 12. Then, the nozzle 7 is rotated, so that the nozzle 7 rotates and drives the connecting seat 9 to rotate, so that the locking post 15 is in the locking groove 13. At this time, the nozzle 7 is no longer pushed, so that the nozzle 7 falls under its own weight, so that the locking groove 13 locks the locking post 15, thereby completing the fixation of the connecting seat 9. During the flight of the drone body 1, the water pump 6 draws pesticide from the liquid tank 5, so that the pesticide enters the transfer pipe 3, and then enters the nozzle 7 through the connecting pipe 8 and the connecting seat 9 and sprays out, completing the spraying of pesticide.

[0033] Similarly, when it is necessary to disassemble the nozzle 7, push the nozzle 7 so that the slot 13 no longer jams the pin 15. Then rotate the nozzle 7 to pull it out, thus completing the quick disassembly of the nozzle 7.

[0034] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
