Description

Technical Field

[0001] This utility model relates to the field of agricultural drone technology, specifically an agricultural drone that is easy to replenish with pesticide solution. Background Technology

[0002] Agricultural drones, as unmanned aerial vehicles used for protecting agricultural and forestry plants, are the culmination of the deep integration of modern technology and agricultural production. Primarily using ground remote control or GPS flight control systems, they precisely perform key operations such as spraying pesticides, seeds, and powders. They have become an indispensable part of the unmanned aerial vehicle field. Today, agricultural drones are ubiquitous in farmland, orchards, and woodlands across the country, and their functions are constantly expanding. They have evolved from simple pesticide spraying into versatile tools integrating pesticide application, fertilization, sowing, pollination, feed distribution, and field patrol, becoming trusted farming tools. Looking to the future, with continuous technological innovation and iteration, agricultural drones will continue to advance towards intelligence, multi-functionality, and precision, playing an even more crucial role in agricultural production and injecting strong momentum into ensuring food security and promoting agricultural modernization.

[0003] For example, patent CN208242678U discloses an agricultural drone that facilitates pesticide spraying. The drone includes a fuselage, supporting legs around the bottom of the fuselage, a supporting plate between the supporting legs, fixing plates at both ends of the surface of the supporting plate, a clamping plate on one side of the fixing plate, a pesticide tank between the clamping plates, a pesticide pump and a dispensing pipe on the outer surface of the pesticide tank, a second hydraulic telescopic rod at the bottom of the supporting plate, a connecting rod at the lower end of the second hydraulic telescopic rod, and pesticide supply pipes connected to both ends of the connecting rod. Fixing frames are provided on the supporting legs, and arms are provided on both sides of the fuselage, with propellers at the ends of the arms. However, the existing device uses a common connection structure for the liquid replenishment tube, which requires multiple operations by the operator during installation. This process is cumbersome and time-consuming. After frequent use, the connection is prone to loosening due to wear, causing the replenishment tube to fall off. This not only interrupts the dosing process but may also cause liquid leakage, reducing the dosing speed and operational efficiency of the drone. Furthermore, the internal structure of the medicine tank is simple, and during long-term storage or flight, the solute in the liquid is very likely to precipitate and condense, adhering to the inner wall, bottom, and near the outlet of the medicine tank. This is not only difficult to clean but can also block the outlet, affecting the normal output of subsequent liquids.

[0004] Therefore, in order to solve this problem, we propose an agricultural drone that is easy to refill with pesticide solution. Utility Model Content

[0005] The purpose of this invention is to provide an agricultural drone that facilitates pesticide refilling, addressing the problems mentioned in the background section. Existing devices use a common connection structure for the pesticide refill tube, requiring multiple installation operations by the operator, which is cumbersome and time-consuming. Furthermore, after frequent use, the connection is prone to loosening due to wear, causing the refill tube to detach, interrupting the refilling process and potentially causing pesticide spillage, thus reducing the drone's refilling speed and operational efficiency. Additionally, the simple internal structure of the pesticide tank allows solutes in the pesticide solution to easily precipitate and adhere to the inner wall, bottom, and near the outlet during prolonged storage or flight. This precipitate is difficult to clean and can clog the outlet, affecting subsequent pesticide output.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plant protection drone that facilitates pesticide replenishment, comprising a drone body, a top groove on the top of the drone body, a pesticide tank installed inside the top groove, a lower pesticide inlet pipe fixedly connected to the top of the pesticide tank, a lower connector fixedly connected to the top of the lower pesticide inlet pipe, grooves evenly distributed on the top of the lower connector, engaging grooves on both sides of the inner wall of the grooves, an upper connector on the top of the lower connector, an upper pesticide inlet pipe fixedly connected to the top of the upper connector, fixing blocks evenly fixedly connected to the bottom of the upper connector, limiting grooves on both sides of the outer wall of the fixing blocks, limiting blocks movably connected to both ends of the limiting grooves, springs fixedly connected between the limiting blocks, and engaging blocks fixedly connected to the outer wall of the limiting blocks.

[0007] Furthermore, the bottom of the lower connector is uniformly threaded with bolts, and the bolts penetrate the top of the lower connector and extend into the locking block.

[0008] Furthermore, a water inlet channel is fixedly connected to the left side of the top of the medicine box, and a sealing cap is fixedly connected to the top of the water inlet channel.

[0009] Furthermore, rotating rods are rotatably connected to both ends of the outer wall of the medicine box, a servo motor is fixedly connected to the front end of the left rotating rod, and a stirring rod is fixedly connected to the outer wall of the rotating rod.

[0010] Furthermore, a drive gear is fixedly connected to the front end of the left rotating rod on the outer wall of the medicine box, and a driven gear is fixedly connected to the front end of the right rotating rod on the outer wall of the medicine box, with the drive gear and the driven gear meshing together.

[0011] Furthermore, a medicine discharge pipe is fixedly connected to the bottom of the medicine tank, and the medicine discharge pipe penetrates the bottom of the drone body. A pump body is fixedly connected to the outer wall of the medicine discharge pipe, and an atomizing nozzle is fixedly connected to the bottom of the medicine discharge pipe.

[0012] Furthermore, a sealing groove is provided at the top of the lower drug inlet tube, and a sealing block that matches the sealing groove is fixedly connected to the bottom of the upper drug inlet tube, and the sealing groove and the sealing block are annular in shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are: a plant protection drone that facilitates pesticide refilling adopts a novel structural design, the specific details of which are as follows:

[0014] (1) This plant protection drone that facilitates the replenishment of pesticide solution uses a linkage design of spring, limit block, locking block and locking groove to enable quick plug-in and fixation of the lower and upper connectors: when the upper connector is pressed down, the locking block is squeezed inward by the inner wall of the locking groove. When the fixing block is fully embedded in the groove, the spring pushes the limit block to reset, so that the locking block is accurately locked into the locking groove. The entire installation process does not require the assistance of tools and a single person can complete the docking in a short time. At the same time, the bolt passes through the lower connector and locks the locking block to form a double anti-loosening structure, which solves the problem of detachment caused by wear in traditional connections, reduces the pesticide leakage rate, ensures continuous and stable pesticide application, and significantly increases the daily operating area of ​​the drone.

[0015] (2) The plant protection drone that facilitates the replenishment of pesticide solution has components such as rotating rods, stirring rods, active gears and driven gears on the outer wall of the pesticide tank working together. The servo motor at the front end of the left rotating rod drives the active gear to rotate. The active gear and the driven gear mesh and connect, so that the two sets of stirring rods rotate relative to each other and stir the pesticide solution in the tank. In this way, during long-term storage or flight, it can effectively prevent the solute in the pesticide solution from precipitating and condensing and adhering to the inner wall, bottom and near the outlet of the tank, avoiding blockage of the outlet and ensuring the normal output of subsequent pesticide solution.

[0016] Furthermore, the water inlet channel and sealing cap located on the top left side of the medicine tank facilitate the addition of water and other liquids to meet the needs of different medicine solutions. The medicine discharge pipe at the bottom of the medicine tank runs through the bottom of the drone body, and the pump body on the outer wall can control the discharge volume of the medicine solution. The atomizing nozzle at the bottom can atomize the medicine solution, making the medicine solution sprayed evenly and improving the effect of plant protection operations. The sealing groove at the top of the lower medicine inlet pipe matches the sealing block at the bottom of the upper medicine inlet pipe, and the shape is ring-shaped, which enhances the sealing of the connection and prevents the medicine solution from leaking.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides the following technical solution: an agricultural drone that facilitates the replenishment of pesticide solutions.

[0029] Example 1: An agricultural drone designed for easy pesticide refilling utilizes a spring 171, a limiting block 17, a locking block 172, and a locking groove 131 to securely install the lower connector 13 and the upper connector 15. Bolts 14 are then used to fix the locking block 172 into the locking groove 131. This design prevents the pesticide refill tube from using a conventional connection structure, which requires multiple installation operations, is cumbersome and time-consuming, and is prone to loosening due to wear after frequent use, leading to the refill tube detaching. This not only interrupts the pesticide application process but may also cause pesticide spillage, reducing the drone's refilling speed and operational efficiency. Figure 1 - Figure 6As shown, a plant protection drone that facilitates pesticide refilling includes a drone body 1. A top groove is formed on the top of the drone body 1, and a pesticide tank 11 is installed inside the top groove. A lower pesticide inlet pipe 12 is fixedly connected to the top of the pesticide tank 11, and a lower connector 13 is fixedly connected to the top of the lower pesticide inlet pipe 12. The top of the lower connector 13 has evenly spaced grooves, and engaging grooves 131 are formed on the inner walls of both sides of the grooves. An upper connector 15 is provided on the top of the lower connector 13, and an upper pesticide inlet pipe 151 is fixedly connected to the top of the upper connector 15. Fixing blocks 16 are evenly fixedly connected to the bottom of the upper connector 15. Limiting grooves are provided on both outer walls of the fixing block 16. Limiting blocks 17 are movably connected to both ends of the limiting grooves. Springs 171 are fixedly connected between the limiting blocks 17. Engaging blocks 172 are fixedly connected to the outer wall of the limiting blocks 17. Bolts 14 are evenly threaded at the bottom of the lower connector 13, and the bolts 14 penetrate the top of the lower connector 13 and extend into the interior of the engaging blocks 172. A sealing groove is provided at the top of the lower drug inlet tube 12. A sealing block matching the sealing groove is fixedly connected to the bottom of the upper drug inlet tube 151. The sealing groove and the sealing block are annular in shape.

[0030] When medication needs to be replenished, the upper connector 15 is placed on top of the lower connector 13. The fixing block 16 at the bottom of the upper connector 15 is inserted into the groove at the top of the lower connector 13. Under the action of the spring 171, the limiting blocks 17 in the limiting grooves on both sides of the fixing block 16 drive the locking block 172 to extend outward. The locking block 172 is locked into the locking grooves 131 on both sides of the groove of the lower connector 13, thereby achieving the initial fixation of the lower connector 13 and the upper connector 15. Then, the bolt 14 passes through the top of the lower connector 13 and extends into the locking block 172 to further fix the locking block 172 in the locking groove 131 to ensure the connection is firm. In this way, the upper medicine inlet tube 151 and the lower medicine inlet tube 12 are connected and medication can be replenished.

[0031] Example 2: Unlike Example 1, through the coordinated action of components such as the rotating rod 2, stirring rod 21, driving gear, and driven gear, the two sets of stirring rods 21 can rotate relative to each other. This prevents the simple internal structure design of the medicine tank 11 from causing the solute in the medicine solution to easily precipitate and condense on the inner wall, bottom, and near the outlet of the medicine tank 11 during long-term storage or flight. This precipitate is not only difficult to clean but also blocks the outlet, affecting the normal output of subsequent medicine solutions. Figure 7 - Figure 9As shown, a water inlet channel is fixedly connected to the top left side of the medicine tank 11, and a sealing cover is fixedly connected to the top of the water inlet channel. Rotating rods 2 are rotatably connected to both ends of the outer wall of the medicine tank 11. A servo motor is fixedly connected to the front end of the left rotating rod 2. A stirring rod 21 is fixedly connected to the outer wall of the rotating rod 2. A drive gear is fixedly connected to the front end of the left rotating rod 2 on the outer wall of the medicine tank 11. A driven gear is fixedly connected to the front end of the right rotating rod 2 on the outer wall of the medicine tank 11. The drive gear and the driven gear are meshed. A medicine discharge pipe 3 is fixedly connected to the bottom of the medicine tank 11. The medicine discharge pipe 3 penetrates the bottom of the drone body 1. A pump body is fixedly connected to the outer wall of the medicine discharge pipe 3. An atomizing nozzle 31 is fixedly connected to the bottom of the medicine discharge pipe 3.

[0032] Start the servo motor at the front end of the left rotating rod 2. The servo motor drives the left rotating rod 2 to rotate, and the drive gear at the front end of the left rotating rod 2 rotates accordingly. Since the drive gear is meshed with the driven gear at the front end of the right rotating rod 2, the drive gear drives the driven gear to rotate, which in turn makes the right rotating rod 2 rotate. The stirring rods 21 on the outer wall of both rotating rods 2 rotate together with the rotating rods 2. The two sets of stirring rods 21 rotate relative to each other, stirring the liquid in the medicine tank 11 to prevent the solute in the liquid from precipitating. When the liquid in the medicine tank 11 needs to be sprayed, start the pump body on the outer wall of the discharge pipe 3. The pump body draws the liquid in the medicine tank 11 out through the discharge pipe 3. After the liquid is atomized by the atomizing nozzle 31 at the bottom of the discharge pipe 3, it is evenly sprayed onto the crops to complete the plant protection operation.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
