Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an unmanned aerial vehicle for hoisting and mounting agricultural and sideline products. Background Art

[0002] UAV, the full name of which is "Unmanned Aerial Vehicle" (UAV for short), is an aircraft that does not carry an operator and flies through remote control or autonomous control. UAVs can carry a variety of mission payloads, such as cameras, infrared, radars, etc., and perform a variety of tasks, including military tasks such as reconnaissance, surveillance, communication relay, electronic countermeasures, target indication, and attack, as well as civilian tasks such as aerial photography, agricultural monitoring, logistics distribution, and disaster relief. There are many types of UAVs, among which lifting and mounting UAVs are UAVs specially designed for lifting cargo or performing lifting tasks.

[0003] Agricultural and sideline products refer to products other than the main products produced in the agricultural production process. These products are usually by-products of crops or direct outputs of other agricultural activities such as animal husbandry, fishery, forestry, etc. In the process of allocating and transporting agricultural and sideline products in remote areas or places with inconvenient transportation, in order to achieve fast and efficient logistics distribution, lifting and mounting drones are often used to lift agricultural and sideline products to designated locations.

[0004] Most of the existing agricultural and sideline products lifting and mounting drones have a simple structure. The support frame at the bottom of the drone body is generally fixed by bolts or welding, which makes it difficult to disassemble and install the support frame part, so that the drone body occupies a large space when stored and is not convenient to move and transfer. In addition, the existing agricultural and sideline products lifting and mounting drones cannot ensure the stability of the agricultural and sideline products during the process of lifting and mounting the agricultural and sideline products, which makes the agricultural and sideline products easy to shake during air transportation, thereby affecting the normal flight of the drone and posing certain safety hazards. Therefore, the present invention proposes an agricultural and sideline products lifting and mounting drone to solve the problems existing in the prior art. Summary of the invention

[0026] A concave seat 8 with a concave shape is welded and fixed in the middle position at the bottom end of the top plate 5. A winding roller 9 is arranged inside the concave seat 8, and the winding roller 9 is driven by the winding and unwinding mechanism and rotates forward or reversely. A lifting rope 10 is wound around the winding roller 9, and the end of the lifting rope 10 is fixed on the winding roller 9. The lifting rope 10 can be wound or unwound while the winding roller 9 rotates. A horizontal hanging plate 11 is fixed to the bottom end of the lifting rope 10, and an agricultural and sideline product lifting bag 12 for loading agricultural and sideline products is hung at the bottom end of the hanging plate 11. The top of 11 is symmetrically provided with an embedding groove 13, and the embedding groove 13 is adapted to the concave seat 8.

The other end of the limit spring 32 is fixedly connected to the rebound sheet 31. The limit spring 32 provides elastic force for the rebound sheet 31, so that the reboundable pin 27 has a rebound and reset function and can automatically rebound into the socket 29.

[0034] When agricultural and sideline products need to be hoisted for transportation, first load the agricultural and sideline products to be transported into the agricultural and sideline products lifting belt 12 (ensure that the weight of the agricultural and sideline products is evenly distributed during loading to avoid excessive tilting of the hanging plate 11 during lifting), then control the drone body 1 to hover just above the agricultural and sideline products lifting belt 12, then use the winding and unwinding mechanism to drive the winding roller 9 to rotate and unwind the lifting rope 10, so that the hanging plate 11 at the bottom of the lifting rope 10 drops to the position of the agricultural and sideline products lifting belt 12, and then manually hang the hanging ring 15 at the top of the agricultural and sideline products lifting belt 12 on the hook 14 at the bottom of the hanging plate 11 , realize the lifting connection of the agricultural and sideline products lifting bag 12 at the bottom end of the hanging plate 11, at this time, the winding and unwinding mechanism is used to drive the winding roller 9 to rotate in the opposite direction and reel in the lifting rope 10, so that the hanging plate 11 at the bottom end of the lifting rope 10 drives the agricultural and sideline products lifting bag 12 to rise, and rise to the position where the bottom end of the concave seat 8 is inserted into the fitting groove 13 at the top end of the hanging plate 11. At this time, the hanging plate 11 is limited and fixed by the concave seat 8 relative to the drone body 1, and is not easy to shake in the air. Then the drone body 1 is controlled to fly to the destination and perform the corresponding unloading work, that is, the lifting and transportation of agricultural and sideline products is completed;

[0035] When the agricultural and sideline products lifting and mounting drone needs to be stored for mobile transfer, the elastic positioning mechanism first releases the clamping fixation between the top plate 5 and the mounting plate 6, and then the mounting plate 6 is removed from the bottom end of the top plate 5, and then the support frame 7 can be removed from the bottom of the drone body 1 to complete the convenient disassembly work, reduce the occupied space of the agricultural and sideline products lifting and mounting drone, and make the drone body 1 convenient for storage and mobile transfer. During installation, first dock the mounting plate 6 at the bottom end of the top plate 5, and then use the elastic positioning mechanism to clamp and fix the mounting plate 6 to the bottom end of the top plate 5.
