Description

Technical Field

[0001] This invention relates to the field of agricultural plant protection technology, specifically to a drone-borne pesticide delivery device and its usage method. Background Technology

[0002] In agricultural pest and disease control, traditional pesticide spraying methods suffer from low efficiency, high labor costs, and significant pesticide waste, and are also difficult to operate in complex terrains (such as mountains and forests). With the development of drone technology, drone-borne pesticide delivery devices are gradually being applied to agricultural plant protection, but current technology still has the following shortcomings:

[0003] Insufficient transmission and load-bearing stability: Existing devices mostly use a single chain or belt drive to carry pesticide projectiles, with the transmission structure and load-bearing structure separated, lacking a two-way force balance design. When the pesticide projectile is placed on the load-bearing component, the center of gravity is easily shifted due to the concentrated force on a single transmission component, and there is no effective limiting mechanism to constrain the movement trajectory of the load-bearing component. Turbulence during UAV flight (such as airflow disturbances and fuselage swaying caused by terrain undulations) can directly cause the pesticide projectile to shift, get stuck, or even fall out of the load-bearing component, seriously affecting the delivery accuracy and operational continuity.

[0004] Difficulty in controlling the timing of release: Due to the lack of effective buffer and delay mechanisms, pesticide bullets are prone to deviations in ignition timing due to excessive speed during the process from storage to release, or uneven release intervals due to jamming.

[0005] Cumbersome to operate: Most devices require manual loading of pesticide bullets one by one, or frequent manual adjustments during the deployment process, and have weak adaptability to drone automated operations;

[0006] Insufficient safety: The triggering logic of the ignition mechanism is not rigorous, which can easily lead to false ignition or ignition delay, posing a safety hazard.

[0007] Therefore, there is an urgent need for a drone-borne pesticide delivery device that is accurate, easy to operate, and highly safe to meet the needs of efficient agricultural plant protection. Summary of the Invention

[0008] The purpose of this invention is to provide a drone-borne pesticide munition delivery device and its usage method, to solve the problem of insufficient transmission and load-bearing stability of existing devices mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a drone-borne pesticide munition delivery device, comprising two drive gears rotatably connected to the rear side of the inner wall of a connecting housing, a drive component being provided in the connecting housing to drive the upper drive gear to rotate; the two drive gears mesh with a drive chain, and a plurality of first rounded triangular blocks are equidistantly arranged on the drive chain, the two ends of the first rounded triangular blocks being fixed to the ends of two adjacent chain shafts of the drive chain;

[0009] The remaining end of the first rounded triangular block is rotatably connected to the lifting link. The lifting link consists of two vertically staggered rectangular plates and a round rod, which is used to receive the power of the driving chain and drive the driven chain to achieve synchronous transmission between the two.

[0010] A limiting plate is fixed along the inner wall of the connecting shell. A guide plate is provided on the inner wall of the limiting plate. The guide plate is fixed to the connecting block and is fixed to the rear side of the inner wall of the connecting shell through the connecting block.

[0011] A racetrack-shaped channel is formed between the guide plate and the limiting plate. The round rod is slidably installed in the racetrack-shaped channel. Two rectangular plates are distributed on the front and rear sides of the limiting plate. The racetrack-shaped channel restricts the sliding path of the lifting linkage. Driven gears are rotatably connected to the upper and lower sides of the front of the guide plate. The two driven gears mesh with the driven chain, and the driven chain is located in front of and below the driving chain. Multiple second rounded triangular blocks are equidistantly arranged on the driven chain. The two ends of the second rounded triangular blocks are fixed to the ends of the two adjacent chain shafts of the driven chain, and the remaining ends of the second rounded triangular blocks are rotatably connected to the front rectangular plate.

[0012] The second rounded triangular block is rotatably connected to the support shaft. The rear end of the support shaft passes through the second rounded triangular block and is fixed to the front rectangular plate. The front end of the support shaft is fixed to the storage frame.

[0013] Preferably, the driving component includes a bidirectional motor mounted on the back of the connecting housing, the bidirectional motor shaft being fixedly connected to a worm gear, the worm gear meshing with a worm wheel; a transmission rod is fixedly inserted inside the worm wheel, the transmission rod being rotatably connected to the back of the connecting housing, its front end extending into the interior of the connecting housing and fixed at the central shaft of the upper drive gear; the worm gear and worm wheel cooperate to achieve self-locking and speed reduction transmission of the drive gear, and to regulate the pesticide bullet dispensing interval.

[0014] Preferably, a discharge port is opened on the left side of the connecting shell, and multiple obliquely arranged guide rods are rotatably connected to the front side of its inner wall. The guide rods guide the pesticide bullets on the storage frame to the temporary storage frame. The temporary storage frame is fixed to the left side of the connecting shell, and two damping spring telescopic rods are obliquely fixed to the left side of the inner wall of the temporary storage frame. The damping spring telescopic rods are higher on the right and lower on the left to guide the pesticide bullets to move to the left side of the temporary storage frame. The right ends of the two damping spring telescopic rods extend through the discharge port into the connecting shell and are fixed to the arc-shaped extrusion block. The arc-shaped extrusion block is compressed by the extrusion of the storage frame, which drives the damping spring telescopic rods to compress.

[0015] Each damping spring telescopic rod has a through groove inside, and three sliding blocks are slidably installed in the through groove. The sliding blocks have guide grooves, and a drive rod that is vertically fixed in the through groove is slidably connected in the guide grooves. The sliding blocks are also rotatably connected to a rotating rod. The sliding blocks and the rotating rod cooperate to receive and release pesticide bullets when the damping spring telescopic rod extends or retracts.

[0016] Preferably, two longitudinally parallel fixed plates are also fixed inside the connecting shell, and the sliding block is inserted through the fixed plates to ensure stable back-and-forth movement;

[0017] An igniter is installed on the top of the inner wall of the temporary storage frame. The igniter is triggered to ignite when the pesticide bullet enters a specific position in the temporary storage frame. A rotating connecting rod is rotated on the left side of the inner wall of the temporary storage frame to reduce the friction of the falling pesticide bullet. An opening is provided on the left side of the connecting shell, and an opening and closing door is inserted on the upper side of the inner wall of the opening to close the opening and prevent the pesticide bullet from falling accidentally.

[0018] Preferably, the connecting shell has semi-circular ends and a rectangular middle section to adapt to the drone's carrying space and optimize the internal structural layout.

[0019] Preferably, the storage frame consists of a rectangular plate and four rotating rods. The four rotating rods are connected to the rectangular plate in a U-shape, which is used to adaptively fit the shape of the pesticide bullet and enhance the load-bearing stability.

[0020] Preferably, multiple guide rods are arranged at an angle with the tilt direction facing the temporary storage frame to form a guide ramp to guide the pesticide bullet smoothly into the temporary storage frame.

[0021] Preferably, the opening and closing door and the opening connecting the outer shell are in a sliding fit, and the sliding direction of the opening and closing door is vertical, so as to realize the rapid opening and closing of the opening by sliding up and down, which facilitates the loading of pesticide bullets.

[0022] A method for using a drone-borne pesticide delivery device includes the following steps:

[0023] S1, Loading Stage

[0024] Pulling up the opening door starts the bidirectional motor to rotate forward, driving the upper drive gear via the worm gear, worm wheel, and transmission rod, causing the drive chain to rotate clockwise; the first rounded triangular block drives the lifting linkage, whose round rod slides along the racetrack-shaped channel, and the front rectangular plate pulls the driven chain to rotate synchronously, causing the storage box to move upward with the second rounded triangular block; the user puts the pesticide pellets into the storage box (the U-shaped rotating rod provides stable support), and after completion, turns off the bidirectional motor (the worm gear and worm wheel self-lock in place), and closes the opening door;

[0025] S2, Flight Standby Phase

[0026] The device is installed on the drone. The worm and worm wheel are self-locking, the active and driven chains are stationary, the storage frame is stably loaded with ammunition, and the damping spring telescopic rod of the temporary storage frame naturally extends and is ready to be used.

[0027] S3, Deployment and Ignition Phase

[0028] When the drone arrives at the target area, the bidirectional motor reverses and the active chain rotates counterclockwise. The storage box moves to the guide rod, and the pesticide bullet slides into the temporary storage box through the guide rod. The storage box squeezes the arc-shaped extrusion block, causing the damping spring telescopic rod to contract. The drive rod slides along the guide groove of the sliding block, which drives the rotating rod to close and receive the pesticide bullet. Then, the igniter is triggered to ignite. After the damping spring telescopic rod (51) is reset, the rotating rod opens, and the pesticide bullet slides down through the rotating rod to complete the deployment.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] This invention: This invention fundamentally solves the problem of unstable center of gravity during load-bearing processes by using a bidirectional transmission structure of "active chain - lifting link - driven chain" combined with rigid connection and forced limiting design.

[0031] The active chain is rotatably connected to the front and rear rectangular plates of the lifting link through the first rounded triangular block and the driven chain through the second rounded triangular block, forming a two-way force balance structure. After the storage frame carries the pesticide bullet, the weight is transmitted to the second rounded triangular block through the support shaft and then simultaneously distributed to the first rounded triangular block through the lifting link, so that the active and driven chains share the load and avoid the center of gravity tilting forward or sideways due to the force on a single chain.

[0032] The runway-shaped channel formed by the guide plate and the limiting plate forcibly limits the round rod of the lifting linkage, constraining the storage box to slide only along the preset trajectory. Even if the drone experiences turbulence during flight in complex terrain, the channel can limit the offset range of the round rod and pull the center of gravity of the storage box back to the fitting area, effectively preventing the pesticide bullet from shifting, getting stuck, or falling.

[0033] The first and second rounded triangular blocks are rigidly connected to the chain by fixing both ends to the adjacent chain shaft, forming an integrated load-bearing unit with the chain. This avoids chain deformation caused by single-point force and further prevents the storage frame from sinking due to chain deformation, making it suitable for dynamic flight environments such as mountains and forests.

[0034] This invention features controllable delivery accuracy and interval: By utilizing a bidirectional motor in conjunction with the self-locking and deceleration functions of a worm gear, the transmission speed of the driving chain and the driven chain can be precisely controlled, achieving precise control of the pesticide bullet delivery interval; at the same time, the buffer mechanism composed of a damping spring telescopic rod and a rotating rod provides a stable time window for pesticide bullet ignition and delivery, improving delivery accuracy.

[0035] This invention is simple and efficient to operate: the storage box is moved in a cycle by an active chain, which makes it convenient for users to load pesticide bullets in batches without the need for manual adjustment of each one; the entire delivery process is automated, and the delivery operation can be completed by controlling the bidirectional motor to turn it, which is suitable for the remote control needs of drones.

[0036] This invention enhances safety by linking the igniter's triggering logic with the pesticide projectile's transmission path, ensuring that ignition is triggered only when the pesticide projectile enters a specific position in the temporary storage box, thus preventing accidental ignition. Simultaneously, the opening and closing door design prevents the pesticide projectile from accidentally falling during loading and flight, improving operational safety.

[0037] This invention features a compact structure and strong adaptability: the connecting shell adopts a design that combines semi-circular and rectangular shapes, resulting in a compact overall structure, lightweight design, and easy installation on various drones. Furthermore, the slanted design of the guide rod and temporary storage frame further optimizes the utilization of internal space, making it suitable for small-sized drones.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Please see Figures 1 to 8 This invention provides a technical solution: a drone-borne pesticide delivery device, comprising a connecting shell 1, with two drive gears 2 rotatably connected to the rear side of the inner wall of the connecting shell 1, and a driving component on the connecting shell 1 for driving the upper drive gears 2 to rotate. A drive chain 21 meshes with the two drive gears 2, and multiple first rounded triangular blocks 22 are equidistantly arranged on the drive chain 21. The two ends of the first rounded triangular blocks 22 are fixedly connected to the ends of two adjacent chain shafts on the drive chain 21. The two ends of the first rounded triangular blocks 22 are fixed to the ends of the two adjacent chain shafts on the drive chain 21, and the two ends of the second rounded triangular blocks 29 are fixed to the ends of the two adjacent chain shafts on the driven chain 28. This rigid connection method makes the triangular blocks and the chain form an "integrated load-bearing unit" rather than a single-point force-bearing structure. When the storage frame 211 carries the pesticide projectile, the center of gravity load is transferred to the second rounded triangular block 29 through the support shaft 210, and is jointly borne by the adjacent chain shafts of the driven chain 28. Similarly, the first rounded triangular block 22 on the active side also distributes the load through the adjacent chain shafts of the active chain 21, avoiding chain deformation caused by excessive force on a single chain shaft, thereby preventing the center of gravity of the storage frame 211 from sinking or tilting due to chain deformation, ensuring that the pesticide projectile always maintains a stable attitude in the storage frame 211, which is suitable for the dynamic flight environment of UAVs operating in complex terrain (such as mountains and forests).

[0049] The remaining end of the first rounded triangular block 22 is rotatably connected to a lifting link 23, which consists of two vertically staggered rectangular plates 231 and a round rod 232.

[0050] The connecting shell 1 has semi-circular ends and a rectangular middle section. A limiting plate 24 is fixedly connected to the inner wall of the connecting shell 1. The inner wall of the limiting plate 24 has a guide plate 25. A connecting block 212 is fixedly connected to the guide plate 25. The guide plate 25 is fixed to the rear side of the inner wall of the connecting shell 1 through the connecting block 212. A racetrack-shaped channel 26 is formed between the guide plate 25 and the limiting plate 24. A round rod 232 is slidably disposed in the racetrack-shaped channel 26. Two rectangular plates 231 are distributed on the front and rear sides of the limiting plate 24.

[0051] Driven gears 27 are rotatably connected to the upper and lower sides of the front of the guide plate 25. Driven chains 28 mesh on the two driven gears 27, and the driven chains 28 are located in front of and below the driving chain 21. The racetrack-shaped channel 26 formed by the guide plate 25 and the limiting plate 24 provides a forced limiting effect on the round rod 232 of the lifting link 23, so that when the lifting link 23 drives the storage frame 211 to move along the driving chain 21 and the driven chain 28, it can only slide along the preset racetrack-shaped path. This design can effectively constrain the degree of freedom of movement of the storage frame 211 and avoid lateral displacement or vertical swaying of the storage frame 211 due to the turbulence of the UAV flight. Even if the pesticide bullet has a slight center of gravity shift due to inertia, the racetrack-shaped channel 26 can pull the center of gravity of the storage frame 211 back to the preset trajectory by limiting the sliding range of the round rod 232, preventing the pesticide bullet from shifting or falling out of the storage frame 211 due to instability.

[0052] The driving chain 21 is rotatably connected to the rear rectangular plate 231 of the lifting link 23 via the first rounded triangular block 22, and the driven chain 28 is rotatably connected to the front rectangular plate 231 of the lifting link 23 via the second rounded triangular block 29, forming a two-way transmission structure of "driving side - lifting link - driven side". When the storage frame 211 carries the pesticide bullet, its weight is transmitted to the front second rounded triangular block 29 through the support shaft 210, and then simultaneously distributed to the first rounded triangular block 22 of the driving chain 21 via the lifting link 23. This allows the driving chain 21 and the driven chain 28 to bear part of the weight of the storage frame 211 and the pesticide bullet, respectively, avoiding the center of gravity bias caused by the force on a single chain (such as relying solely on the driven chain 28, which easily causes the center of gravity to tilt forward), ensuring that the storage frame 211 is subjected to balanced force and that the center of gravity is always kept in the central adaptation area of ​​the transmission mechanism.

[0053] Multiple second rounded triangular blocks 29 are evenly spaced on the driven chain 28. The two ends of the second rounded triangular blocks 29 are fixedly connected to the ends of two adjacent chain shafts on the driven chain 28. The remaining end of the second rounded triangular block 29 is rotatably connected to the front rectangular plate 231.

[0054] A support shaft 210 is rotatably connected to the second rounded triangular block 29. The rear end of the support shaft 210 passes through the second rounded triangular block 29 and is fixed to the front rectangular plate 231. A storage frame 211 is fixedly connected to the front end of the support shaft 210. The storage frame 211 consists of a rectangular plate and four rotating rods. The four rotating rods are connected to the rectangular plate in a U-shape to ensure the stability of the pesticide bullets stored in the storage frame 211.

[0055] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8As shown, the driving component includes a bidirectional motor 11 mounted on the back of the connecting housing 1. A worm gear 12 is fixedly connected to the rotating shaft of the bidirectional motor 11. The worm gear 12 and the worm wheel 13 have a self-locking function to prevent the drive gear 2 from rotating. The speed reduction cooperation between the worm gear 12 and the worm wheel 13 helps to control the pesticide bullet dispensing interval. The worm gear 12 is meshed with the worm wheel 13, and a transmission rod 14 is fixedly inserted inside the worm wheel 13. The transmission rod 14 is rotatably connected to the back of the connecting housing 1. The front end of the transmission rod 14 extends into the interior of the connecting housing 1 and is fixedly connected to the central shaft of the upper drive gear 2.

[0056] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, a discharge port 3 is provided on the left side of the connecting shell 1. Multiple obliquely arranged guide rods 4 are rotatably connected to the front side of the inner wall of the connecting shell 1. These obliquely arranged guide rods 4 help to guide the pesticide on the storage frame 211 inside the connecting shell 1 into the temporary storage frame 5. The temporary storage frame 5 is located at the tail of the UAV in the direction of flight.

[0057] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, a temporary storage frame 5 is fixedly connected to the left side of the connecting shell 1. Two damping spring telescopic rods 51 are fixedly connected to the left side of the inner wall of the temporary storage frame 5 at an angle, with the right side of the damping spring telescopic rods 51 being higher than the left side, to ensure that the pesticide bullet moves stably on the left side of the inner wall of the temporary storage frame 5. The right ends of the two damping spring telescopic rods 51 extend into the connecting shell 1 through the discharge port 3 and are fixedly connected to an arc-shaped extrusion block 56. The arc-shaped extrusion block 56 can drive the damping spring telescopic rods 51 to compress under the extrusion of the storage frame 211.

[0058] Each damping spring telescopic rod 51 has a through groove 52 on its inner rod. Three sliding blocks 53 are slidably arranged in the through groove 52. A guide groove 54 is provided on the sliding block 53. A drive rod 55 is slidably connected in the guide groove 54. The drive rod 55 is vertically fixed in the through groove 52. A rotating rod 58 is also rotatably connected to the sliding block 53.

[0059] Two longitudinally parallel fixed plates 57 are also fixedly connected inside the connecting housing 1. The sliding block 53 is inserted through the fixed plate 57. The fixed plate 57 ensures that the sliding block 53 moves back and forth stably. An igniter 59 is installed on the top of the inner wall of the temporary storage frame 5. The ignition switch of the igniter 59 is installed on the upper side of the inner wall of the temporary storage frame 5. This is existing technology and will not be described in detail here. When the pesticide bullet moves from inside the connecting housing 1 into the temporary storage frame 5, it touches the switch of the igniter 59 and activates the igniter 59 through the switch to ignite the pesticide bullet.

[0060] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, a rotating rod 6 is rotatably connected to the left side of the inner wall of the temporary storage frame 5, which can reduce the friction when the pesticide bullet falls inside the temporary storage frame 5.

[0061] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, an opening is provided on the left side of the connecting shell 1, and an opening and closing door 7 is inserted through the upper side of the inner wall of the opening.

[0062] The method of use and advantages of this invention: The working process of this UAV-borne pesticide delivery device is as follows:

[0063] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 8 As shown, by pulling up the door 7, pesticide pellets are placed into the storage frame 211 through the opening on the left side of the connecting shell 1. Then, the bidirectional motor 11, in conjunction with the worm gear 12, drives the worm wheel 13 to rotate, causing the transmission rod 14 to drive the drive chain 21 to rotate clockwise. When the drive chain 21 rotates clockwise, it works with the first rounded triangular block 22 to pull the rear rectangular plate 231, causing the round rod 232 to slide in the racetrack-shaped channel 26. At the same time, it drives the front rectangular plate 231 to pull the driven chain 28 to rotate clockwise, causing the second rounded triangular block 29 to move the storage frame 211 upward, thus making it convenient for the user to place the pesticide pellets into the storage frame 211 one by one.

[0064] After storage is completed, close the opening and closing door 7. Connect the connecting shell 1 to the drone and move the connecting shell 1 through the drone. When the drone moves the connecting shell 1 to the area where pesticide bullets need to be released, start the bidirectional motor 11 to rotate in the opposite direction, drive the active chain 21 to rotate counterclockwise, and cooperate with the lifting link 23 to drive the driven chain 28 to rotate counterclockwise, causing the pesticide bullets on the storage frame 211 to rotate counterclockwise. The multiple guide rods 4 set at an inclination receive the pesticide bullets on the storage frame 211, causing the pesticide bullets to slide into the temporary storage frame 5.

[0065] As the storage frame 211 moves below the guide rod 4, the side of the storage frame 211 near the inner wall of the connecting housing 1 presses the arc-shaped pressing block 56, causing the two damping spring telescopic rods 51 to contract. When the inner rod of the damping spring telescopic rod 51 contracts, it slides in the guide groove 54 through the drive rod 55, and the pressing drive rod 55 moves towards the side near the fixed plate 57. At this time, the two sets of rotating rods 58 move relative to each other to receive the pesticide bullets guided to the temporary storage frame 5. At this time, the pesticide bullets are ignited by the igniter 59. When the inner rod of the damping spring telescopic rod 51 resets under its own spring reset force, the two sets of sliding blocks 53 move in opposite directions. When the damping spring telescopic rod 51 has completed its reset, the two sets of rotating rods 58 have completed their opposite reset, and the pesticide bullets are then released.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
