[0002] Drones, due to their advantages of being flexible, responsive, unmanned flight, and low operation requirements, can achieve real-time image transmission under conditions such as high-risk areas by carrying various sensors. They are a powerful supplement to satellite remote sensing and traditional aerial remote sensing. With the rapid development of drone technology, the plant information collection by drones usually installs a camera for plant information collection on the drone, starts the drone to fly at a certain altitude, and then starts the camera to take pictures of ground vegetation to achieve the collection of plant information.

[0003] Currently, the camera structure of the existing plant information collection device based on a drone is difficult to be quickly and stably installed on the drone, and during the process of approaching the vegetation for collection and shooting, the relative height of the camera cannot be adjusted as needed, which affects the collection efficiency of the device. Therefore, we propose a plant information collection device based on a drone. Content of the Utility Model

[0024] Embodiment 1

[0025] Please refer to Figures 1-4 As shown in the figure, the present utility model provides a technical solution: a plant information collection device based on a drone, including a drone body 1. A positioning seat 5 is fixedly connected to the middle end of the bottom of the drone body 1. A positioning card slot 15 is opened at the front end of the inner cavity top of the positioning seat 5. The longitudinal section of the positioning card slot 15 is a right triangle. A positioning block 6 is inserted inside the positioning seat 5. A groove 13 corresponding to the positioning card slot 15 is opened at the front end of the top of the positioning block 6. A spring 14 is fixedly connected to the bottom of the inner cavity of the groove 13. The top of the spring 14 is fixedly connected to a positioning card block 16 that moves inside the groove 13. The upper end of the positioning card block 16 is adapted to the positioning card slot 15, and the upper end of the positioning card block 16 is clamped inside the positioning card slot 15. The lower end of the front surface of the positioning card block 16 is fixedly connected to a pushing member 17 that extends outside the positioning block 6. The top view section of the pushing member 17 is T-shaped. A middle end of the bottom of the positioning block 6 is fixedly connected to an adjustment sleeve 7. A lifting motor 8 is fixedly installed at the middle end of the inner cavity top of the adjustment sleeve 7. The output end of the lifting motor 8 is fixedly connected to an adjustment screw rod 12. An adjustment rod 11 is threadedly connected to the outer surface of the adjustment screw rod 12. An information collection camera 3 is fixedly installed at the bottom of the adjustment rod 11. The upper end of the outer surface of the adjustment rod 11 is fixedly connected to a movable ring 9. Guide rods 10 that slide on the inner surface of the movable ring 9 are fixedly connected to the left and right ends of the bottom of the inner cavity of the adjustment sleeve 7.

[0026] Technical solution: Through the setting of the positioning seat 5, when driving the positioning block 6 into its inner side, affected by the inclined surface at the top of the positioning block 16, during the process of the positioning block 6 entering the positioning seat 5, the positioning block 16 can be compressed and retracted into the groove 13 to compress the spring 14. When the positioning block 6 can no longer move in the positioning seat 5, the compressed spring 14 can drive the positioning block 16 to move in the groove 13 in the reverse direction. Then, the upper end of the positioning block 16 can be clamped inside the positioning slot 15, so that the information collection camera 3 can be quickly installed through the positioning block 6. On the contrary, after driving the positioning block 16 to retract into the groove 13 again to compress the spring 14 by the pushing member 17, the upper end of the positioning block 16 can exit the inside of the positioning slot 15. Then, making the positioning block 6 exit the positioning seat 5 can realize the quick disassembly of the information collection camera 3. When the device works and the information collection camera 3 needs to be height-adjusted when collecting information close to the vegetation at a short distance, the lifting motor 8 drives the adjusting screw rod 12 to rotate forward or backward. With the cooperation of the guide rod 10 and the movable ring 9, the adjusting rod 11 can move up and down on the outer surface of the adjusting screw rod 12. With the movement of the adjusting screw rod 12, the information collection camera 3 can be height-adjusted, which can more effectively improve the collection speed of vegetation information.

A buffer spring 19 sleeved outside the damper 18 is fixedly connected between the top of the buffer leg 4 and the top of the inner cavity of the support sleeve 2.

[0029] Technical solution: Through the setting of the support sleeve 2, when the unmanned aerial vehicle body 1 lands, the buffer leg 4 can first contact the ground, and with the setting of the damper 18 and the buffer spring 19, it can effectively buffer and protect the unmanned aerial vehicle body 1 and the information collection camera 3.
