Description

Technical Field

[0001] This utility model belongs to the field of drone fertilization technology, and in particular relates to a fertilizer feeding device for drone fertilization. Background Technology

[0002] With the continuous development of modern agricultural technology, drone technology is being used more and more widely in agricultural production, especially in plant protection, sowing, and fertilization. Due to its advantages such as high efficiency, flexibility, and low cost, drone fertilization is gradually becoming an important part of modern agriculture. Drone fertilization, as an emerging fertilization method, can effectively solve the problems of low efficiency, uneven coverage, and high labor intensity associated with traditional manual fertilization and ground-based mechanical fertilization.

[0003] However, during the feeding process, drones lack a reliable positioning and fixing structure, making them prone to displacement or shaking due to external forces. This can cause the feed pipe to misalign with the drone's feed storage structure, affecting feeding efficiency and potentially causing fertilizer leakage, increasing operating costs and cleanup burden. Furthermore, the feed storage components of drones are mostly static storage structures. If the fertilizer is not thoroughly stirred during the feeding and spraying process, sedimentation and stratification can easily occur, leading to uneven fertilizer concentration during application. Excessive fertilizer concentration in some areas may burn crops, while insufficient concentration will fail to achieve the desired fertilization effect, severely impacting fertilization quality.

[0004] To address these issues, we provide a fertilizer dispensing device for drone fertilization. Utility Model Content

[0005] The purpose of this invention is to provide a fertilizer feeding device for drone fertilization. Through the action of a positioning plate, which, pushed by a threaded rod, can tightly fit against the drone's support frame, effectively fixing the drone during feeding and preventing it from shaking or shifting, thus ensuring the stability of the feeding operation. Several anti-slip blocks fixed to the surface of the positioning plate increase the friction between it and the support frame, further enhancing the stability of the fixation. This solves the problem that existing drones lack a reliable positioning and fixing structure during feeding, making them prone to displacement or shaking due to external forces. This can lead to misalignment between the feed pipe and the drone's storage structure, affecting feeding efficiency and potentially causing fertilizer leakage, increasing operating costs and cleaning burden.

Specific Implementation Example 1

[0046] Please see Figure 1-9This utility model is a fertilizer feeding device for drone fertilization, including a drone body 1 and a feeding shell 2. The drone body 1 is located above the feeding shell 2. A feeding box 3 is fixed above the feeding shell 2. The feeding box 3 is connected to a first water pump 4 through a first water pipe. The output end of the first water pump 4 is connected to a conveying pipe 5. A limit pipe 6 is fixed on one side of the feeding shell 2. The conveying pipe 5 passes through the limit pipe 6. A connecting rod 7 is fixed at the bottom of the drone body 1. An installation groove 8 is fixed at one end of the connecting rod 7. An installation strip 9 is slidably connected inside the installation groove 8. A water storage tank 10 is fixed on one side of the installation strip 9. An inlet pipe 11 is fixed on one side of the water storage tank 10. A valve 12 is fixed on the outside of the inlet pipe 11. Support plates 13 are fixed on both sides of the feeding shell 2. An installation plate 14 is fixed on the upper surface of the support plate 13. A threaded pipe 15 is fixed on the surface of the installation plate 14. A threaded rod 16 is threadedly connected inside the threaded pipe 15. A positioning plate 17 is fixed on the side of the threaded rod 16 near the feeding shell 2.

[0047] Specifically, a handle 18 is fixed to the end of the threaded rod 16 away from the positioning plate 17, and several anti-slip blocks 19 are fixed to the surface of the positioning plate 17.

[0048] Furthermore, the mounting strip 9 has a "T" shaped structure and matches the inner wall of the mounting groove 8; a limiting groove 20 is opened on one side of the mounting groove 8; a tension spring 21 is fixed to the top of the mounting groove 8, a connecting plate 22 is fixed to one end of the tension spring 21, and a baffle 23 is fixed to one end of the connecting plate 22; the baffle 23 passes through the limiting groove 20; brackets 24 are fixed to both sides of the drone body 1; a second water pump 25 is connected to both sides of the water tank 10 through a second water pipe, and a diversion pipe 26 is connected to the output end of the second water pump 25 through a third water pipe; a nozzle 27 is fixed to one end of the diversion pipe 26.

[0049] The operation process of this embodiment is as follows: Control the drone body 1 to fly directly above the feeding shell 2, and slowly land so that the support 24 at the bottom of the drone is between the support plates 13 on both sides of the feeding shell 2. Rotate the handle 18 on the support plates 13 on both sides of the feeding shell 2 to drive the threaded rod 16 to move along the threaded tube 15 towards the support 24 until the positioning plate 17 is in contact with the surface of the support 24. Use the anti-slip block 19 on the positioning plate 17 to enhance the friction and prevent the drone from shaking during feeding. Connect the output end of the conveying pipe 5 to the inlet pipe 11 on one side of the water tank 10. Open the valve 12 on the outside of the inlet pipe 11 and start the first water pump 4. The fertilizer in the feeding tank 3 enters the first water pump 4 through the first water pipe, and is pumped into the water tank 10 through the conveying pipe 5 and the inlet pipe 11. After feeding is completed, rotate the handle 18 in the opposite direction so that the threaded rod 16 drives the positioning plate 17 away from the support 2. 4. Release the drone from its fixed position. During fertilization, control the drone to take off and move to the fertilization area. Start the second water pump 25. The fertilizer in the water tank 10 enters the second water pump 25 through the second water pipe, and is then transported to the diversion pipe 26 through the third water pipe. Finally, it is evenly sprayed out by the nozzle 27 at one end of the diversion pipe 26. The positioning plate 17 can be tightly attached to the bracket 24 of the drone body 1 by the push of the threaded rod 16. It can effectively fix the drone during the feeding process, prevent the drone from shaking or shifting, and ensure the stability of the feeding operation. Several anti-slip blocks 19 fixed on the surface of the positioning plate 17 can increase the friction between it and the bracket 24, further improving the fixation. The stirring rod 35 can reciprocate under the drive of the motor 30, which plays a stirring role in the fertilizer in the water tank 10, ensuring that the fertilizer is mixed evenly and avoiding local concentrations that are too high or too low, thus ensuring the fertilization effect. Specific Implementation Example 2

[0051] Please see Figure 4-6 Based on the first specific embodiment, the top of the water storage tank 10 is connected to the tank cover 28 by bolts, and the surface of the tank cover 28 has an adjustment groove 29; a motor 30 is fixed to the top of the tank cover 28, and the output shaft of the motor 30 is fixed to the main drive rod 31; the end of the main drive rod 31 away from the motor 30 is rotatably connected to the driven rod 32, and the end of the driven rod 32 away from the main drive rod 31 is rotatably connected to the adjustment rod 33.

[0052] Specifically, a limiting rod 34 is fixed to the top of the box cover 28, and an adjusting rod 33 passes through the inner wall of the limiting rod 34; the limiting rod 34 passes through the adjusting groove 29, and a number of stirring rods 35 are fixed to one end of the limiting rod 34.

[0053] The operation process of this embodiment is as follows: To prevent fertilizer from settling in the water storage tank 10, the motor 30 at the top of the water storage tank 10 can be started. The output shaft of the motor 30 drives the main transmission rod 31 to rotate. The main transmission rod 31 pulls the adjusting rod 33 from the transmission rod 32, causing the adjusting rod 33 to move back and forth within the limiting rod 34. The stirring rod 35 at the bottom of the limiting rod 34 moves back and forth synchronously with the adjusting rod 33 to stir the fertilizer in the water storage tank 10 and ensure uniform mixing. When it is necessary to disassemble and clean the water storage tank, pull the connecting plate 22 at the top of the mounting groove 8 to stretch the tension spring 21, causing the baffle 23 to be pulled out from the limiting groove 20. Since the mounting strip 9 has a "T" shaped structure and matches the inner wall of the mounting groove 8, the mounting strip 9 can be pulled out horizontally along the mounting groove 8, and then the water storage tank 10 can be removed for cleaning. After washing, reinsert the mounting strip 9 into the mounting slot 8, loosen the connecting plate 22, and the tension spring 21 resets, causing the baffle 23 to pass through the limiting slot 20, thus re-fixing the mounting strip 9. If the stirring structure needs to be cleaned, unscrew the fixing bolts of the box cover 28, remove the box cover 28, clean the stirring rod 35 and other components, and then reassemble and fix them. When the water tank 10 needs to be cleaned, pull the connecting plate 22 to pull the baffle 23 out of the limiting slot 20, and the mounting strip 9 can be pulled out of the mounting slot 8, making it easy to remove the water tank 10 for thorough cleaning of its interior, avoiding residual fertilizer clumping or contamination of subsequent fertilizers. The detachable structure means that when the water tank 10 is damaged or needs to be replaced, there is no need to disassemble the drone body 1 or other components in a complicated manner, reducing maintenance difficulty and cost, and at the same time, it is convenient to repair or replace the water tank 10 separately.
