Crop rotation planning, water use analysis, weed mapping, and pest detection are all applications that unmanned aerial vehicles can provide.

[0003] Crop image acquisition unmanned aerial vehicles can direct resources such as pesticides / herbicides of farmers to the places where they are most needed, while reducing the cost and waste of crop protection products. Crop image acquisition unmanned aerial vehicles provide unparalleled accuracy during the data collection process. However, when the existing crop image acquisition unmanned aerial vehicles conduct image acquisition while flying above the crops, when the propeller blades of the crop image acquisition unmanned aerial vehicle are close to the crops, the generated wind is extremely likely to cause wind interference to the crops, causing the crops to fall and scatter, resulting in inconvenient image acquisition due to the change of crop images during the acquisition of crop images, and the crop image acquisition unmanned aerial vehicle can only fly above the crops to conduct image acquisition of the crops, and it is inconvenient to shuttle through the crops for close-range image acquisition.

[0004] Therefore, a crop image acquisition unmanned aerial vehicle with the function of preventing wind interference with crops is proposed to solve the above problems. Content of the Utility Model

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1-4, an embodiment provided by the present utility model: A crop image acquisition drone with the function of preventing wind interference with crops, including a drone body 1. A drone propeller 2 is fixedly installed on the top of the drone body 1. A fixed pipe 3 is connected to the top of the drone body 1. The fixed pipe 3 can be placed outside the drone propeller 2 to reduce the interference of the wind dissipated outward during the use of the drone propeller 2, preventing the wind flowing around the drone propeller 2 from spreading in all directions and causing wind interference to the crops below. A protective sleeve 4 is threadedly connected to the bottom of the fixed pipe 3. The protective sleeve 4 can reduce the range of the wind spreading outward below the drone propeller 2, reducing the wind interference of the drone propeller 2 on the crops. A protective plate 20 is connected to the bottom of the protective sleeve 4. The protective plate 20 is placed at the bottom of the protective sleeve 4 to prevent broken leaves from entering the protective sleeve 4 below and affecting the drone propeller 2. A protective net ring 21 is threadedly connected to the top of the fixed pipe 3. The protective net ring 21 can filter the air at the top of the fixed pipe 3, preventing crop broken leaves from entering it from above the fixed pipe 3. A fixing plate 5 is connected to the back of the drone body 1. The fixing plate 5 can limit the movable rod 6 and the rotating plate 8. The movable rod 6 is movably connected to the inside of the fixing plate 5. A motor one 7 is connected to the left side of the movable rod 6. The right side of the motor one 7 is fixedly installed with the left side of the fixing plate 5. A rotating plate 8 is connected to the surface of the movable rod 6. After the motor one 7 drives the movable rod 6 to rotate, the rotating plate 8 rotates and moves downward from the bottom of the drone body 1. A motor two 9 is fixedly installed on the front of the rotating plate 8. A screw rod 10 is connected to the front of the motor two 9. A moving plate 11 is threadedly connected to the surface of the screw rod 10. After the motor two 9 is started, it drives the screw rod 10 to rotate, so that the screw rod 10 threadedly drives the moving plate 11 to move downward and adjust inside the rotating plate 8, so that the image acquisition camera 13 is pushed and further descends. Stabilizing blocks 18 are connected to both sides of the moving plate 11. The stabilizing blocks 18 are longitudinally slidably connected to the inside of the rotating plate 8. The stabilizing blocks 18 can limit both sides of the moving plate 11, making the movement of both sides of the moving plate 11 in the rotating plate 8 more stable. The moving plate 11 is slidably connected to the inside of the rotating plate 8. An adjusting plate 12 is movably connected to the inside of the moving plate 11. The adjusting plate 12 can support the image acquisition camera 13 and can drive the image acquisition camera 13 to rotate on the adjusting plate 12 under the drive of a motor three 19, and can adjust the image acquisition angle of the image acquisition camera 13, facilitating the user to rotate and adjust the image acquisition angle of the image acquisition camera 13 according to the needs of crop image acquisition. A motor three 19 is fixedly installed on the outside of the adjusting plate 12. The motor three 19 can actively adjust the angle of the image acquisition camera 13 in the adjusting plate 12. The output end of the motor three 19 is fixedly installed on the surface of the image acquisition camera 13. An image acquisition camera 13 is movably connected to the bottom of the adjusting plate 12. A landing shock absorber is fixedly installed at the bottom of the drone body 1, so as to reduce the wind interference during crop image acquisition, facilitate clear acquisition of crop images, and be able to shuttle between crops for close-range image acquisition.

[0033] Referring to Figures 1-3 , the landing shock absorber includes a landing mounting rod 141, which is fixedly installed at the bottom of the unmanned aircraft body 1. A buffer shock pad 142 is connected to the bottom of the landing mounting rod 141. The landing mounting rod 141 can drive the buffer shock pad 142 to be installed at the bottom of the unmanned aircraft body 1. When the unmanned aircraft body 1 lands, the buffer shock pad 142 first contacts the ground without generating a strong impact force on the components inside the unmanned aircraft body 1 and the image acquisition camera 13, so as to achieve the function of shock-absorbing landing during the landing of the unmanned aircraft body 1.

[0034] Referring to Figures 2-4 , a wind deflector 15 is movably connected to the surface of the landing mounting rod 141, and the inner side of the wind deflector 15 contacts the surface of the landing mounting rod 141; a support plate 16 is longitudinally connected inside the landing mounting rod 141. The outer side of the wind deflector 15 is threadedly connected with a positioning bolt 17, and the inner side of the positioning bolt 17 is threadedly connected with the surface of the support plate 16. After the positioning bolt 17 is disengaged from the support plate 16, the wind deflector 15 can be placed at the bottom of the drone blade 2. When the air flowing downward during the flight of the drone blade 2 is blocked, the wind interference of the drone blade 2 on the crops is further reduced.

[0035] Working principle: When in use, the fixed tube 3 can be placed outside the drone blade 2 to reduce the interference of the outwardly divergent wind during the use of the drone blade 2, preventing the wind flowing around the drone blade 2 from spreading and causing wind interference to the crops below. The protective cover 4 can reduce the range of the wind diffusing outward below the drone blade 2. The unmanned aircraft body 1 drives the drone blade 2 to fly in the air, so that the unmanned aircraft body 1 drives the image acquisition camera 13 to fly above the crops. Then, the motor one 7 is started to drive the movable rod 6 inside the fixed plate 5 to rotate. The movable rod 6 drives the rotating plate 8 and the image acquisition camera 13 at the bottom of the moving plate 11 to rotate and move downward. Then, the motor two 9 is driven to drive the screw rod 10 to rotate, so that the screw rod 10 threadedly drives the moving plate 11 and the adjusting plate 12 to move further downward. The adjusting plate 12 drives the image acquisition camera 13 to move downward. Then, the image acquisition camera 13 can be moved downward away from the unmanned aircraft body 1 to the side of the crops that need to be imaged, and the image of the crops is acquired. Moreover, the image acquisition camera 13 after the moving plate 11 moves downward and is adjusted can descend between multiple crops, and the image of the crops can be acquired at close range. Moreover, it can shuttle between the crop fields to acquire the images of the crops at close range, so as to reduce the wind interference during the acquisition of the crop images, facilitate the clear acquisition of the crop images, and can shuttle between the crops to acquire the images at close range.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
