Detailed Implementation

[0026] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0027] Example:

[0028] As shown in Figures 1 to 6, this utility model provides a reusable seeding device for drones, comprising:

[0029] The suspension bracket 1 is detachably attached to the support frame of the UAV 9 and is located on the side of the diagonal bar on the support frame;

[0030] Crossbar 2 is mounted on suspension bracket 1;

[0031] The suspension rope 3 has one end attached to the crossbar 2 via a locking ring 6;

[0032] The boom 4 is mounted on the reusable aerial seeder 10, and the other end of the rope 3 is connected to the boom 4 via a collar 7. The boom 4 can be fixedly welded to the reusable aerial seeder 10, or it can be detachably connected to the reusable aerial seeder 10.

[0033] The pre-tensioning component 5 is located on the locking ring 6 and the collar 7, and is detachably connected to the crossbar 2 and the lifting rod 4. As a locking component between the lifting rope 3 and the lifting rod 4 and the crossbar 2, the pre-tensioning component 5 effectively prevents the lifting rope 3 from detaching from the lifting rod 4 and the crossbar 2, ensuring the operational stability of the reusable seeding device.

[0034] The reusable seeding device of this utility model is mainly used for the rapid replacement of the reusable aerial seeder 10 during the aerial seeding process of drones.

[0035] Referring to Figures 2 and 5, the suspension frame 1 of this utility model includes a first suspension frame 11 and a second suspension frame 12. The first suspension frame 11 and the second suspension frame 12 have a "V" shaped structure. Both ends of the first suspension frame 11 and the second suspension frame 12 are provided with snap-fit ​​grooves 13, allowing them to be detachably fastened to the support frame of the UAV 9 via the snap-fit ​​grooves 13. The first suspension frame 11 and the second suspension frame 12 are located on the sides of the inclined bars on both sides of the support frame, and are horizontally locked to the support frame by a locking crossbar 2.

[0036] Referring to Figures 3 and 4, the pre-tightening component 5 of this invention is a pre-tightening bolt. An arc-shaped piece 8 is provided on one side of the locking ring 6 and the collar 7, and the pre-tightening bolt is threaded onto the arc-shaped piece 8. Several threaded holes are provided on the crossbar 2 and the lifting rod 4 for connection with the pre-tightening bolt. The pre-tightening bolt passes through the arc-shaped piece 8 and connects to the threaded holes on the crossbar 2 and the lifting rod 4. Furthermore, multiple threaded holes are spaced axially on the crossbar 2 and the lifting rod 4 to adjust the hanging distance of the three lifting ropes 3.

[0037] As another embodiment of this utility model, as shown in Figures 2 and 5, the first suspension frame 11 and the second suspension frame 12 of this utility model are provided with through holes at their upper ends, and the crossbar 2 is located in the through holes; the first suspension frame 11 and the second suspension frame 12 are provided with locking bolts 14, which are connected to the locking screw holes on the crossbar 2. The crossbar 2 can be locked onto the first suspension frame 11 and the second suspension frame 12 by the locking of the first suspension frame 11, the second suspension frame 12 and the crossbar 2, so that the horizontal movement of the first suspension frame 11 and the second suspension frame 12 is limited by the diagonal bars on both sides of the support frame, which can effectively prevent the problem of sliding on the support frame.

[0038] In another embodiment of this utility model, the suspension rope 3 includes a traction safety rope 31, a first traction anti-overturning rope 32, and a second traction anti-overturning rope 33. The first traction anti-overturning rope 32 and the second traction anti-overturning rope 33 are sleeved at both ends of the crossbar 2 via locking rings 6. The traction safety rope 31 is sleeved on the crossbar 2 via locking rings 6 and is located between the first traction anti-overturning rope 32 and the second traction anti-overturning rope 33. The suspension rope 3 is made of steel cable to provide suspension strength for the rotating aerial seeder 10.

[0039] In another embodiment of the present invention, a limiting piece 15 is provided at the end of the first suspension frame 11 and the second suspension frame 12. The limiting piece 15 is provided to further limit the first suspension frame 1 and the second suspension frame 12 to prevent the buckle groove 13 from disengaging from the support frame.

[0040] Referring to Figure 5, the limiting piece 15 is provided with a limiting groove 16, so that the limiting piece 15 can be fastened to the inclined rod of the support frame by means of the ring fastener through the limiting groove 16.

[0041] As an alternative to this embodiment, the limiting piece 15 is provided with mounting holes, which can be connected to the diagonal rod on the support frame using bolts or screws.

[0042] In another embodiment of this utility model, the hanging rod 4 is inserted into the housing of the reusable aerial seeder 10, allowing for quick replacement of the reusable aerial seeder 10 through this insertion method. Furthermore, there are two hanging rods 4, each inserted into one side of the reusable aerial seeder 10. The reusable aerial seeder 10 is equipped with an insertion interface, allowing for quick insertion of the hanging rods 4. Simultaneously, insertion through holes are provided on the hanging rods 4 and the insertion interface, and a pin is inserted into the insertion through hole to further limit and lock the inserted hanging rods 4.

[0043] The working principle of this utility model:

[0044] Referring to Figure 7, after the reusable seeder 10, carrying seeds, returns to the feeding point during the seeding flight of the drone 9, the drone 9 places the reusable seeder 10 on the ground and hovers it above. Then, it disconnects the reusable seeding device (composed of the suspension frame 1, crossbar 2, rope 3, and boom 4) from the reusable seeder 10 at the connection point. The drone 9 then hovers above another reusable seeder 10 and connects the reusable seeding device to the attachment point on the seed-filled reusable seeder 10. After connection, the drone 9 takes off for the next seeding flight.

[0045] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
