Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to an adjustable-type drone for agricultural photography. Background Technology

[0002] In agricultural planting, regular inspections and image sampling of crops are conducted to understand their layout, growth, and appearance changes in a timely manner. With social development and technological progress, the use of drones for inspection and information collection has gradually replaced the traditional manual information collection method. This not only improves efficiency but also allows access to areas that are inaccessible to humans. For example, during rice planting, the fields are filled with water, and humans cannot reach the central area of ​​the crops to collect information.

[0003] However, when using drones equipped with cameras for inspection to capture images of crops, the environment, and their growth, the drones need to descend to a lower altitude to approach the crops. This causes the high-speed rotation of the propellers to create airflow, resulting in localized winds. This winds can cause crops around the drone to sway and even fall over. For example, the wind generated by the drone propellers can be too strong and blow over seedlings (seedlings have shallow roots and are easily lodged). This not only damages the crops but also makes it difficult to clearly capture key information such as the appearance and growth of the crops due to their constant movement. Summary of the Invention

[0004] Based on this, this application provides an agricultural adjustable shooting drone to solve the technical problem in the prior art that when using drones to shoot crops for information collection, the wind generated by the propellers can easily disturb the crops and prevent accurate information from being obtained.

[0005] The technical solution to the above-mentioned technical problems in this application is as follows: An agricultural adjustable-mode photography drone includes: Flight components, used for flight in the air; A winding assembly, which is disposed on the flight assembly and is capable of rotating along a horizontal virtual axis; A suspension assembly, wherein multiple suspension assemblies are sequentially hinged end to end, and one of the suspension assemblies at the end is disposed on the winding assembly, the winding assembly being able to drive multiple suspension assemblies to wind around it; the suspension assembly includes a limiting part, the limiting part being able to block on one side of the rotation direction of two adjacent suspension assemblies, so that the two adjacent suspension assemblies stop after rotating to the same straight line; A clamping component is disposed on the winding component and can cooperate with the winding component to clamp the suspension component into a vertical state; A shooting component is disposed on another suspension component located at the end, and the winding component is capable of driving the shooting component to adjust the distance between it and the flight component in the height direction.

[0006] Preferably, the winding assembly includes a housing with an opening at the lower end, and a rotating assembly that can rotate within the housing, one of the suspension assemblies located at the end being connected to the rotating assembly and capable of extending through the opening into the housing, the housing being connected to the flight assembly.

[0007] Preferably, the winding assembly further includes a driving part disposed on the housing for driving the rotating assembly to rotate.

[0008] Preferably, the rotating assembly includes a rotating roller and a turntable portion disposed on the rotating roller, the turntable portion being able to prevent the suspension assembly from moving along the length direction of the horizontal rotation axis.

[0009] Preferably, the turntable includes a winding disc and guard plates disposed on both sides of the winding disc. The winding disc is connected to the rotating assembly and located inside the housing. A plurality of the suspension assemblies can be wound around the side of the winding disc and are located between the two guard plates.

[0010] Preferably, the suspension assembly includes a link, a plurality of links are sequentially hinged end to end, and one of the links at the end is connected to the turntable portion, and the limiting portion is disposed at the end of the link.

[0011] Preferably, the limiting portion includes a stop edge disposed at the end of the connecting rod, wherein the surface of the stop edge near the connecting rod is flush with the surface of the connecting rod.

[0012] Preferably, the flight assembly includes an unmanned aerial vehicle (UAV) and a support portion disposed at the bottom of the UAV, and the winding assembly is connected to the support portion.

[0013] Preferably, the shooting assembly includes a suspension and a camera mounted on the suspension, the suspension being connected to another suspension assembly located at one end.

[0014] Preferably, the pressing assembly includes a telescopic rod connected to the housing, the movable end of the telescopic rod being able to extend into the housing and contact the suspension assembly, and is provided with a fitting portion.

[0015] Compared with the prior art, this application has at least the following advantages: This application provides an adjustable-type drone for agricultural photography. The rotating winding assembly unfolds multiple suspension components wound around it, forming a "suspension chain" suspending the photography component. Because the multiple suspension components are hinged, the gravity of the photography component pulls them towards a direction perpendicular to the horizontal plane. When two adjacent suspension components rotate to the same straight line, a limiting part can limit their rotation, preventing further rotation and keeping them in a straight line. As the multiple suspension components gradually unfold, the distance between the photography component and the flight component increases. Therefore, while the distance between the photography component and the crops remains constant, the height of the flight component above the crops increases, causing the propeller or power unit to move away from the crops. This allows the multiple suspension components to... The suspension component closest to and in contact with the winding component (that is, the uppermost suspension component after unfolding from top to bottom) remains vertical. A clamping component approaches and presses against the last vertical suspension component on the turntable from the side. The clamping component and the turntable work together to clamp the suspension components from both sides, keeping them vertical. With the assistance of the limiting component, multiple suspension components are kept in a vertical straight line, allowing only unidirectional rotation—rotation away from the limiting component. When the flight component moves horizontally (moving away from the limiting component), the limiting component keeps the unfolded suspension components moving in the same straight line, thus keeping them vertical and driving the shooting component to move synchronously. The limiting component prevents adjacent suspension components from rotating, avoiding swaying of the suspension components. It can increase the distance between the flight component and the crops, reduce the interference of the local airflow generated by the flight component on the crops, and at the same time use the limiting part to make multiple deployed suspension components form a straight suspension component, so that the shooting component moves synchronously when the flight component moves, and avoids the two adjacent suspension components from continuing to rotate due to the hinge, which would cause the shooting component to swing in the air, making the shooting component more stable when the flight component moves.

Detailed Implementation

[0018] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.

[0019] It should be noted that the terms “vertical,” “horizontal,” “left,” “right,” “top,” “bottom,” “end,” “top,” and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please refer to Figures 1 to 14In one specific embodiment of this application, An agricultural adjustable-mode photography drone includes: Flight components, used for flight in the air; A winding assembly, which is disposed on the flight assembly and is capable of rotating along a horizontal virtual axis; A suspension assembly, wherein multiple suspension assemblies are sequentially hinged end to end, and one of the suspension assemblies at the end is disposed on the winding assembly, the winding assembly being able to drive multiple suspension assemblies to wind around it; the suspension assembly includes a limiting part, the limiting part being able to block on one side of the rotation direction of two adjacent suspension assemblies, so that the two adjacent suspension assemblies stop after rotating to the same straight line; A clamping component is disposed on the winding component and can cooperate with the winding component to clamp the suspension component into a vertical state; A shooting component is disposed on another suspension component located at the end, and the winding component is capable of driving the shooting component to adjust the distance between it and the flight component in the height direction.

[0022] The flight component can be a flying drone, a remote-controlled aircraft, or other devices and facilities capable of flight. The winding component can be a winch, a spool, or other rotatable devices and facilities. The suspension component can be a metal rod, a tow bar, or other devices and facilities capable of suspending a camera. The limiting part can be a stop plate, a limiter, or other devices and facilities capable of limiting the rotational connection between two adjacent suspension components. The imaging component can be a camera, a webcam, or other devices and facilities capable of capturing images of crops to obtain information. The clamping component can be a clamping plate, a clip, or other devices and facilities capable of contacting the suspension component from multiple points on the side.

[0023] In practical use, in the initial state, multiple suspension components are sequentially connected end to end and wound around the winding component. That is, at this time, the winding component drives the multiple suspension components into a "wound" state, where the distance between the shooting component and the flight component is minimal. Therefore, after takeoff, if shooting is performed directly, the shooting component is close to the flight component, requiring the flight component to lower its altitude. When the shooting component approaches crops, the propeller or power unit of the flight component creates localized "wind" that has the greatest impact on the crops. To prevent the crops from swaying or falling over, the winding component rotates, causing the multiple suspension components wound around it to unfold, forming a "suspension chain" suspending the shooting component. Because the multiple suspension components are hinged, under the influence of the shooting component's gravity, they will be pulled to align in a direction perpendicular to the horizontal plane. When two adjacent suspension components rotate to the same straight line, the limiting part can limit the adjacent two suspension components, preventing them from continuing to rotate and keeping them in a straight line. As the multiple suspension components gradually unfold, the distance between the shooting component and the flight component increases. With the distance between the shooting component and the crop remaining constant, the height of the flight component above the crop increases, moving the propeller or power unit away from the crop. Then, the suspension component closest to the winding component (i.e., the uppermost suspension component after unfolding from top to bottom) is kept vertical. A pressing component approaches and presses down on the last vertical suspension component on the turntable from the side. The pressing component and the turntable work together to... By clamping the suspension components on both sides to keep them vertical, the limiting part can keep multiple suspension components in a vertical straight line, allowing only unidirectional rotation, that is, rotation towards the side away from the limiting part. When the flight component moves horizontally (moving towards the side away from the limiting part), the limiting part can keep the deployed multiple suspension components moving in the same straight line, thereby pushing the suspension components to keep them in a vertical state and driving the shooting component to move synchronously. The limiting part prevents adjacent two suspension components from rotating, avoiding the suspension components from swinging.

[0024] Through the above process, the distance between the flight component and the crops can be increased, the interference of the local airflow generated by the flight component on the crops can be reduced, and the limiting part can be used to make multiple deployed suspension components form a straight suspension component. When the flight component moves, the shooting component moves synchronously, avoiding the two adjacent suspension components from continuing to rotate due to the hinge, which would cause the shooting component to swing in the air. This makes the shooting component more stable when it is suspended in the air when the flight component moves.

[0025] Specifically, an embodiment of the winding component in the above process is provided: The winding assembly includes a housing 201 with an opening 202 at its lower end, and a rotating assembly that can rotate within the housing 201. One of the suspension assemblies located at the end is connected to the rotating assembly and can pass through the opening 202 out of the housing 201. The housing 201 is connected to the flight assembly.

[0026] The rotating component can be a drum, winch, or other rotatable device or facility. That is, when the rotating component rotates, it can drive multiple suspension components to wind around it in sequence to complete the "winding up". Conversely, when the rotating component rotates in the opposite direction, it can realize the unfolding of multiple suspension components. After the multiple suspension components are "wound up", they will be stored in the outer shell 201, achieving a protective effect when not in use. The opening 202 can reserve space for the suspension components to enter and exit the outer shell 201 to avoid interference.

[0027] Furthermore, the rotating assembly includes a rotating roller 203 and a turntable portion disposed on the rotating roller 203, the turntable portion being able to prevent the suspension assembly from moving along the length direction of the horizontal rotation axis.

[0028] The turntable can be a reel, a roller, or other device or facility capable of winding multiple suspension components. During the winding of the suspension components, its sidewalls can restrict movement from the sides of the suspension components, preventing them from swaying along the length of the horizontal virtual axis and improving the stability of the suspension components.

[0029] Specifically, an embodiment of the rotating component in the above process is provided: The rotating assembly includes a rotating roller 203 rotatably connected inside the housing 201, and two bearings 207 disposed at both ends of the rotating roller 203. The two bearings 207 are respectively connected to the side wall of the housing 201, and the turntable is connected to the rotating roller 203.

[0030] One side of the outer casing 201 is open and detachably connected to a cover 210, which facilitates opening the outer casing 201 during use and allows for maintenance and replacement of internal components such as the rotating roller 203 and suspension components. The two sides of the rotating roller 203 are respectively mounted on the cover 210 and the outer casing 201 via bearings 207. When the power unit (motor 204 in the following text) drives the rotating roller 203 to rotate along its own axis, the rotating roller 203 can drive the turntable connected to it to rotate together, so that multiple suspension components connected end to end are wound around the turntable. When the turntable rotates in the opposite direction, the multiple suspension components can be unfolded from the rotating roller 203.

[0031] Specifically, an embodiment of the turntable section in the above process is provided: The turntable includes a winding disc 208 and guard plates 209 disposed on both sides of the winding disc 208. The winding disc 208 is connected to the rotating assembly and is located inside the housing 201. A plurality of the suspension assemblies can be wound around the side of the winding disc 208 and are located between the two guard plates 209.

[0032] In other words, the winding disc 208 is located in the middle of the rotating assembly (the roller 203 mentioned above), and both sides of the winding disc 208 are detachably connected to guard plates 209. This means that the two guard plates 209 form a space within which the winding disc 208 is located. When multiple suspension components are wound around the winding disc 208, the two guard plates 209 restrict the suspension components (connecting rods 301 mentioned below) from both sides, preventing the suspension components from shifting or swaying, i.e., preventing the suspension components from shifting or swaying along the axis of the roller 203. Furthermore, regardless of whether the suspension components are "winding up" or unwinding, they remain between the two guard plates 209, improving the stability of the suspended object. In other words, in conjunction with the vertical restriction of the limiting part, for example... Figure 3 For example, the limiting part prevents the suspension assembly from swinging forward, and the two guard plates 209 prevent the limiting assembly from swinging left and right. Together, they restrict the unfolded suspension assembly in three directions, making the "suspension chain" formed by the multiple unfolded suspension assemblies more stable and preventing it from shaking or swaying in these three directions.

[0033] Furthermore, the winding assembly also includes a driving unit disposed on the housing 201 for driving the rotating assembly to rotate.

[0034] The drive unit can be a geared motor, a rack and pinion, or other devices and facilities capable of driving the rotating assembly to rotate. In other words, during use, the drive unit enables the rotating assembly to rotate along a horizontal axis, thereby causing the turntable to reciprocate as the rotating assembly rotates in both directions, achieving the process of "winding up" or "unwinding up" multiple suspension components.

[0035] In a preferred embodiment, the drive unit includes a motor 204 connected to the housing 201, and the output shaft of the motor 204 is connected to the roller 203.

[0036] In other words, by opening and closing the motor 204, the output shaft of the motor 204 rotates in both directions, driving the rotating roller 203 to reciprocate. This achieves the process of "winding up" or "unwinding" multiple suspension components by driving the turntable to reciprocate. The motor 204 can be a servo motor, controlling the rotation angle of the output shaft of the motor 204. Thus, when cooperating with the rotation of the regular polygonal winding disc 208 (described below), with each corresponding rotation angle, one side of the winding disc 208 will rotate to the side and remain in a vertical state, allowing the suspension components to abut against that side. Furthermore, a protective cover 211 is provided on the outer casing 201. The protective cover 211 is detachably connected to the outer casing 201 and can cover and protect the motor 204 for protection during daily use.

[0037] Specifically, an embodiment of the suspension assembly in the above process is provided: The suspension assembly includes a link 301, and multiple links 301 are sequentially hinged end to end, with one of the links 301 at the end connected to the turntable portion, and the limiting portion is disposed at the end of the link 301.

[0038] Multiple connecting rods 301 are sequentially hinged end to end to form a "suspension chain". Adjacent connecting rods 301 rotate relative to each other. The first connecting rod 301 at the end is connected to the turntable (winding disc 208 mentioned above). When the rotating roller 203 rotates, it can drive the "suspension chain" to wind around the winding disc 208. When the rotating roller 203 rotates in the opposite direction, it can cause the "suspension chain" to unfold from the winding disc 208. The limiting part is set at one end of the connecting rod 301. When two adjacent connecting rods 301 rotate outward to the same straight line, the limiting part will restrict the connecting rod 301 from continuing to rotate, so that the two adjacent connecting rods 301 remain in the same straight line to form a "rod" shape. This keeps the multiple unfolded connecting rods 301 unchanged in the vertical direction. Thus, when the entire device moves the suspended object, the "suspension chain" composed of multiple connecting rods 301 can move synchronously, thereby avoiding swaying. In other words, by using the limiting part, the two hinged connecting rods 301 can only rotate in the direction without the limiting part. So, during winding, the limiting part is located on the side of the connecting rod 301 away from the winding disc 208. The connecting rod 301 can rotate and wind around the winding disc 208 with the adjacent connecting rod 301 in the direction of the rotating roller 203. When the connecting rod 301 unfolds, when the connecting rod 301 rotates to be on the same straight line as the adjacent connecting rod 301, it will be blocked by the limiting part and cannot continue to rotate. At this time, the two adjacent connecting rods 301 remain on the same straight line. So, when the whole device moves the object in the direction in which the connecting rod 301 can rotate, the limiting part can push the connecting rods 301 that are on the same straight line to move, avoiding the situation where the connecting rod 301 rotates and swings in the direction of forward movement due to inertia.

[0039] Specifically, an embodiment of the limiting part in the above process is provided: The limiting part includes a stop 302 disposed at the end of the connecting rod 301, and the surface of the stop 302 near the connecting rod 301 is flush with the surface of the connecting rod 301.

[0040] Reference Figures 11 to 13 The multiple connecting rods 301 are connected end to end and can rotate relative to each other through hinges, while the flange 302 is provided at one end of the connecting rod 301. Figure 13 In the middle, the right end of the left connecting rod 301 is provided with a stop 302, and the left end of the right connecting rod 301 is hinged to the right end of the left connecting rod 301. At this time, the connecting rods 301 are in a state of rotating to the same straight line. At this time, the lower end face of the right connecting rod 301 is in contact with the stop 302 and cannot continue to rotate downward. That is to say, the two adjacent connecting rods 301 can only rotate relative to each other upward. So, in practical applications, Figure 13 The connecting rod 301 rotates 90 degrees clockwise, and the rotating roller 203 is located to the right of the uppermost connecting rod 301. The upper end of the uppermost connecting rod 301 is connected to the rotating roller 203. When the rotating roller 203 rotates clockwise, it will drive multiple connecting rods 301 to wrap around the rotating roller 203. Because the connecting rods 301 can rotate relative to the adjacent connecting rods 301 to the right at this time, the counterclockwise rotation of the rotating roller 203 can be used to make multiple connecting rods 301 unfold in sequence, so that multiple unfolded connecting rods 301 are kept in the same straight line. At this time, the forward direction of the entire device is to the right. That is to say, the stop 302 is located to the left of the connecting rod 301. So when moving to the right, the stop 302 pushes the adjacent connecting rods 301 from the left to move, so that multiple unfolded connecting rods 301 are kept in a vertical straight line and move to the right without swaying. Thus, when moving to the right, the object is kept in a stable state and moves synchronously, making the object more stable when moving to the right.

[0041] In a preferred embodiment: the winding disc is a regular polygonal winding disc. The first connecting rod 301 can be fixed to the winding disc 208, with their surfaces in contact, and the retaining edge 302 located on the side away from the winding disc 208, so as to... Figure 10 For example: Figure 10The connecting rod 301 rotates 90 degrees clockwise. The rotating roller 203 and the winding disc 208 are located to the right of the uppermost connecting rod 301. When the rotating roller 203 rotates clockwise, the winding disc 208 will drive multiple connecting rods 301 to wind around the winding disc 208. At this time, as the connecting rods 301 wind, they enter the space formed by the two guard plates 209. The width of this space is slightly larger than the width of the connecting rods 301, so that after the connecting rods 301 enter this space, they will not shift in the front-to-back direction, but will wind in a spiral shape. Of course, during winding, the connecting rods wound around the winding disc 208... The length of the first coil of connecting rod 301 is less than the length of the second coil of connecting rod 301 wound from the outside onto the first coil of connecting rod 301. Its length can be adjusted according to actual needs, so that multiple connecting rods 301 can be smoothly wound in a spiral shape on the winding disc 208. The polygonal winding disc 208 allows the connecting rods 301 to make surface contact with each other when they are wound together. Compared with direct contact with the roller 203, since the roller 203 is a curved surface and has point contact with the connecting rod 301, it is easy for the connecting rod 301 to bend. The polygonal winding disc 208 is used to prevent the connecting rod 301 from bending.

[0042] Specifically, an embodiment of the flight components in the above process is provided: The flight assembly includes an unmanned aerial vehicle (UAV) 101 and a support portion disposed at the bottom of the UAV 101, and the winding assembly is connected to the support portion.

[0043] The unmanned aerial vehicle (UAV) 101 is equipped with a support unit at its bottom. The support unit can be a support leg, landing gear 102, or other devices and facilities that can support the UAV 101. A mounting bracket 206 is provided on the side of the outer shell 201. The mounting bracket 206 is connected to the landing gear 102 through connectors to complete the installation of the outer shell 201. This allows the winding component, suspension component, and imaging component to be connected to the UAV 101. The UAV 101 can be operated remotely to move in the air.

[0044] Specifically, an embodiment of the shooting component in the above process is provided: The shooting assembly includes a suspension 401 and a camera 402 mounted on the suspension 401, the suspension 401 being connected to another suspension assembly located at both ends.

[0045] The suspension 401 is detachably connected to the suspension assembly (link 301). Specifically, after the multiple links 301 are unfolded, the lowest link 301 is connected to the suspension 401, thereby suspending the camera 402 below the drone 101. The winding assembly is used to drive the unfolding and rewinding of multiple suspension assemblies to adjust the distance between the drone 101 and the camera 402, so that the camera 402 can be close to the crops while keeping the drone 101 away from the crops, avoiding the propeller or other power components from causing airflow that may interfere with the crops. Meanwhile, a positioning pin 403 is provided at the upper end of the suspension 401, and a sleeve 212 is provided at the lower end of the outer shell 201. The positioning pin 403 and the sleeve 212 correspond vertically. When the suspension assembly is wound up to the final state (the state of completion of winding), the positioning pin 403 can be embedded into the sleeve 212 for positioning after the suspension 401 is raised, thereby limiting it in the horizontal direction and preventing the suspension 401 from causing the camera 402 to shake when the drone 101 is in flight.

[0046] Specifically, an embodiment of the pressing and fixing component in the above process is provided: The pressing assembly includes a telescopic rod 205 connected to the housing 201. The movable end of the telescopic rod 205 can extend into the housing 201 to contact the suspension assembly, and is provided with a fitting part.

[0047] The fitting part can be a clamp, or other device or facility that can contact the side of the connecting rod 301 at multiple points in the vertical direction. A telescopic rod 205 is fixed to the outside of the housing 201. When the movable end of the telescopic rod 205 moves the fitting part closer to the suspension assembly (connecting rod 301), see... Figure 2 In the figure, when the rotating roller 203 rotates clockwise, it can unfold the multiple connecting rods 301 wound on the winding disc 208. The connecting rods 301 hang down by their own weight. When the connecting rod 301 closest to the winding disc 208, that is, the uppermost connecting rod 301, is in a vertical state in the unfolded state, the movable end of the telescopic rod 205 drives the fitting part to contact the side of the connecting rod 301 from the right side and apply pressure to clamp the connecting rod 301 on the winding disc 208. The clamping is completed by the restriction of the winding disc 208 from the left side, so that the connecting rod 301 is kept in a vertical state. Figure 14In this design, the winding disc 208 is a regular hexagon. This means that every 60-degree rotation of the winding disc 208 allows a connecting rod 301 to rotate to a vertical position. After each 60-degree rotation, the contacting part presses the connecting rod 301 tightly from the right side, while the left side of the connecting rod 301 is also in surface contact with the winding disc 208. By clamping the two surfaces, the connecting rod 301 is kept in a vertical position without changing. Similarly, the winding disc 208 can be any other regular polygon to meet the requirements. Furthermore, even if the winding disc 208 is circular, the contact point between the winding disc 208 and the connecting rod 301 from the left side is a single point, but the contacting part from the right side is a surface contact or multiple points. Using this design, the connecting rod 301 can still be clamped in a vertical position, preventing wobbling.

[0048] In a preferred embodiment: the bonding portion includes a bonding plate 2051, which is parallel to the direction in which the suspension assembly extends out of the housing 201.

[0049] The bonding plate 2051 is connected to the movable end of the telescopic rod 205. When the rotating roller 203 rotates, the movable end of the telescopic rod 205 retracts, causing the bonding plate 2051 to move away from the connecting rod 301, thereby avoiding interference with the rotation of the winding disc 208 and the movement of the connecting rod 301. When the object is lifted and suspended, the movable end extends, causing the bonding plate 2051 to contact the side of the connecting rod 301 from the right side to complete the clamping, so that the connecting rod 301 remains in a vertical state and does not swing.

[0050] Here, a specific operational procedure is provided for the above process: In the initial state, the motor 204 is in the off state, and the winding disc 208 drives multiple connecting rods 301 to be in the "winding" state. The landing gear 102 is in contact with the ground, and the camera 402 is located below the drone 101. Due to the support of the landing gear 102, it will not contact the ground. Then, the user operates (remotely controls) the drone 101 to take off and fly to a predetermined altitude. At this altitude, the airflow generated by the drone 101's propeller or power unit will not affect the crops below. Then, the motor 204 starts, driving the winding disc 208 to rotate. At this time, the movable end of the telescopic rod 205 retracts, driving the bonding plate 2051 away from the connecting rod 301, thereby avoiding interference with the rotation of the winding disc 208 and the movement of the connecting rod 301, causing multiple connecting rods 301 to unfold. When multiple connecting rods 301 unfold, the camera 402 will descend until it descends to a suitable position above the crops. Then, the motor 204 is turned off. At this time, the uppermost connecting rod 301 among the unfolded multiple connecting rods 301 remains in a vertical state. Then, the movable end extends, driving the bonding plate 2051 to contact the side of the connecting rod 301 from the right side to complete the clamping, so that the connecting rod 301 remains in a vertical state and does not swing. When the camera 402 starts shooting and needs to move, the drone 101 moves along the length of the axis of the rotating roller 203 or away from the side rail 302. When moving in these three directions, the multiple extended links 301 will not rotate relative to each other, but will move vertically as a whole. This ensures that when the drone 101 moves, the camera 402 will not swing in the air, but will keep shooting while moving synchronously with the drone 101.
