Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle seeding, in particular to a flying seeding device for a unmanned aerial vehicle. Background Art

[0002] Aerial seeding devices for drones are designed to achieve efficient and precise seeding operations. They typically consist of a storage silo, a discharging mechanism, seed spreading components, and a control system. The operating principle is that after a drone carrying the aerial seeding device flies to a designated area, the control system activates the discharging mechanism according to preset parameters, discharging the seeds from the storage silo. The seed spreading components then spread the seeds at the appropriate speed and direction, ensuring even distribution across the target area.

[0003] Existing devices primarily use drones equipped with sowing components for aerial seeding. Much of the existing technology resembles a drone aerial seeding device. Patent number CN105173084A describes a structure comprising a drone body, to which an aerial seeding device and an air storage device are connected. The aerial seeding device includes a three-axis seeding device, an auger transmission device, and a seed storage device. The three-axis seeding device is connected to an auger hanger, the auger transmission device is also connected to the auger hanger, and the seed storage device is mounted on the bottom of the drone body. However, this device still has room for improvement.

[0004] The existing devices mainly sow seeds through a single outlet discharge, which makes it difficult for some devices to control the seeds for multi-channel discharge sowing, resulting in inconvenience in controlling the seed sowing density. At the same time, some devices mainly fix the discharge seat on the bracket, which makes it difficult for some devices to adjust the longitudinal spacing of the discharge head according to the seed planting requirements, resulting in inconvenience in adjusting the sowing spacing of the drone, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a flying sowing device for drones is proposed. Utility Model Content
