[0003] Based on the aforementioned document: With the rapid development of drone technology, its application in fields such as agricultural plant protection, emergency rescue, and logistics distribution is becoming increasingly widespread. In many scenarios, it is necessary to use drones to quickly throw multiple spherical objects, such as seed ball throwing in the agricultural field, life-saving material ball throwing in the emergency rescue field, and fire extinguishing bomb throwing in the firefighting field.

[0004] Existing drone-based spherical object delivery devices have significant shortcomings: on the one hand, most devices can only deliver a single object at a time, making it difficult to meet the need for continuous and rapid delivery of multiple spherical objects, resulting in low delivery efficiency and making them unsuitable for scenarios with high delivery speed requirements, such as large-area operations or emergency rescues; on the other hand, some devices with multi-object delivery capabilities lack flexible directional adjustment functions, only able to deliver in a fixed direction, and cannot adjust the delivery angle according to the terrain and target location differences of the actual work area, leading to poor delivery accuracy and the problem of spherical objects deviating from the target area, affecting the operational effect. Therefore, this utility model provides a delivery device for drones to quickly deliver multiple spherical objects. Utility Model Content

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.

[0017] Please see Figure 1-6 This utility model provides a technical solution: A delivery device for rapidly dropping multiple spherical objects from a drone includes a connecting flange 1 for connecting to the drone.

The support rod 412 is located above the connecting rod 411. A connecting plate 413 is fixedly connected to the surface of the connecting rod 411. Placement rings 414 are installed at both ends of the connecting plate 413. The placement rings 414 are fixedly connected to each other by multiple sets of placement rods 415.

A fixing plate 418 is fixedly connected to the other end of the folded plate 416. A return spring 419 is installed on the surface of the folded plate 416. One end of the return spring 419 is fixedly connected to the top of the inner cavity of the main frame 3. The drive component 42 is located at the top of the inner cavity of the main frame 3 and is used to drive the folding plate 416 to rotate to realize the throwing operation of the spherical object.

[0018] The connecting flange 1 is connected and fixed to the bottom connection part of the UAV by multiple sets of bolts; The surface of the placement ring 414 is provided with a placement hole for placing a spherical object; When the return spring 419 is not affected by external force, the groove 6 on the surface of the fixed plate 418 will always be in contact with the surface of the drive rod 424; By incorporating a dispensing mechanism 4 and utilizing the cooperation of dispensing component 41 and drive component 42, multiple spherical objects can be rapidly and continuously dispensed. Driven by drive motor 422, the folding plate 416 and the stop bar 417 rotate clockwise, thereby releasing the stop bar 417 from obstructing the spherical objects. The spherical objects fall under gravity and are dispensed. Subsequently, the folding plate 416 rotates counterclockwise under the elastic force of the return spring 419 to reset, and the stop bar 417 stops the subsequent spherical objects again, awaiting the next dispensing operation. This effectively improves dispensing efficiency and can meet the needs of continuous dispensing of multiple spherical objects.

[0019] In this embodiment, two sets of placement rings 414 and multiple sets of placement rods 415 enclose a spherical object placement chamber, and a limit plate 5 is installed on the inner wall of the rear placement ring 414.

[0020] The limiting plate 5 is used to prevent spherical objects from slipping from behind; In this embodiment, the drive assembly 42 includes a device plate 421 installed on the top of the inner cavity of the main frame 3. A drive motor 422 is fixedly connected to one side of the device plate 421. One end of the output shaft of the drive motor 422 is fixedly connected to a drive disk 423 through a coupling. A drive rod 424 is fixedly connected to one side of the drive disk 423.

[0021] Drive motor 422 is a miniature DC brushless geared motor; In this embodiment, a groove 6 is provided on the surface of the fixing plate 418, and the inner surface of the groove 6 is in contact with the surface of the drive rod 424.

[0022] The drive rod 424 rolls and slides on the inner surface of the groove 6; the inner surface of the groove 6 is arc-shaped. In this embodiment, the rotating assembly 2 includes an equipment plate 21 installed at the bottom of the connecting flange 1. A rotary motor 22 is fixedly connected to the top of the inner cavity of the equipment plate 21. One end of the output shaft of the rotary motor 22 is fixedly connected to a rotary gear 23 through a coupling. The surface of the rotary gear 23 drives the main frame 3 to rotate through the linkage assembly 24.

[0023] Rotary motor 22 is a miniature DC brushless geared motor; There is a gap between the bottom of the equipment plate 21 and the top of the main frame 3; In this embodiment, the linkage assembly 24 includes a linkage rod 241 rotatably mounted at the bottom of the inner cavity of the equipment plate 21. The bottom end of the linkage rod 241 is fixedly connected to the top of the main frame 3. A linkage gear 242 is fixedly connected to the surface of the linkage rod 241, and the surface of the linkage gear 242 meshes with the surface of the rotating gear 23.

[0024] By setting the rotating component 2, the throwing direction can be flexibly adjusted. After the rotating motor 22 is started, its output shaft drives the rotating gear 23 to rotate. The rotating gear 23 drives the linkage gear 242 and the linkage rod 241 to rotate through meshing. The linkage rod 241 drives the main frame 3 to rotate synchronously, thereby adjusting the orientation of the throwing mechanism so that spherical objects can be thrown in different directions, adapting to the throwing position requirements in different operating scenarios and improving the throwing accuracy.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] In use, first, the device is fixedly connected to the drone via the connecting flange 1. The spherical object to be released is placed into the placement chamber formed by the placement ring 414 and the placement rod 415. The spherical object is limited by the limiting plate 5 and the stop bar 417. After the drone flies to the target release position, the rotary motor 22 can be started. The output shaft of the rotary motor 22 drives the rotary gear 23 to rotate. The rotary gear 23 drives the linkage gear 242 and the linkage rod 241 to rotate through meshing. The linkage rod 241 drives the main frame 3 to rotate to the preset release direction. Then, the drive motor 422 is started to drive... The output shaft of the motor 422 drives the drive disc 423 and the drive rod 424 to rotate. The drive rod 424 pushes the fixed plate 418 to move through the groove 6, causing the folding plate 416 to rotate around the support rod 412. The stop bar 417 at one end of the folding plate 416 moves, releasing the obstruction of the spherical object in the placement chamber. The spherical object falls and completes the placement. After placement, the drive motor 422 continues to run. As the drive rod 424 continues to rotate, the folding plate 416 resets under the elastic force of the return spring 419. The stop bar 417 blocks the subsequent spherical object again. Repeated operation realizes the rapid and continuous placement of multiple spherical objects.
