Description

Technical Field

[0001] The present application relates to the field of modern agricultural technology, and in particular to a landing bracket for an agricultural drone. Background Art

[0002] In modern agriculture, drones are increasingly being used, showing great potential in precision agriculture, pest monitoring, and crop spraying. Existing agricultural drones generally use simple landing gear designs, such as fixed or foldable tripods, to meet basic takeoff and landing requirements. However, fixed tripods are difficult to adapt to different terrains, such as muddy, sloped, or complex farmland environments, and can easily cause damage or instability during landing. While foldable tripods can improve portability to a certain extent, they are often complex in structure, cumbersome to deploy and fold, and still bulky when folded, making them inconvenient for long-distance transportation or rapid deployment in emergency situations. Furthermore, some tripod designs lack stability when carrying the weight of the drone and operating equipment, making them prone to tilting or even overturning, especially in strong winds or on uneven ground.

[0003] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0004] In order to solve the problem that fixed tripods are difficult to adapt to different terrains, such as muddy, sloped or complex farmland environments, which can easily cause damage to the drone or insufficient stability during landing; and although foldable tripods can improve portability to a certain extent, they are often complex in structure, and the unfolding and folding operations are cumbersome, and the volume after folding is still large, which is not convenient for long-distance transportation or rapid deployment in emergency situations, the present application provides a landing bracket for agricultural drones.

[0005] The landing bracket for an agricultural drone provided in this application adopts the following technical solution:

[0006] A landing bracket for an agricultural drone includes an agricultural drone, the agricultural drone is equipped with a rotor, a mounting frame is fixed to the bottom of the agricultural drone, fixing blocks are installed on both sides of the mounting frame, a buffer landing rod is connected to the fixing blocks, the buffer landing rod is provided with a support assembly, the support assembly includes a support spring arranged in the mounting frame, the bottom end of the buffer landing rod is fixedly connected to the landing support frame, and the bottom end of the landing support frame is provided with an anti-slip sleeve.

[0007] Preferably, mounting grooves are provided on both sides of the bottom of the agricultural drone, and connecting blocks are welded to both ends of the top of the fixing block in an integral structure, and one end of the connecting block is fixedly connected to the inner wall of the mounting groove.

[0008] Preferably, the outer walls at both ends of the fixing block are connected to mounting bars by screws, the end of the buffer landing rod away from the landing support frame is rotatably connected to the mounting bar, and movable holes are opened at the center of both sides of the fixing block.

[0009] Preferably, a supporting cantilever is rotatably connected inside the movable hole, and one end of the supporting cantilever away from the movable hole is connected to the top end of the landing support frame.

[0010] Preferably, a connecting plate is fixed to the outer wall of the top end of the buffer lifting rod, and the two ends of the support spring are respectively connected to the connecting plate and the inner wall of the mounting groove.

[0012] In summary, this application has the following beneficial technical effects:

[0013] When the agricultural drone of the present application lands and contacts the ground, the landing support frame first contacts the ground to support both sides of the bottom of the mounting frame, providing a stable support base for the drone, ensuring that the drone will not tilt or overturn during landing, and improving the safety of landing. The setting of the anti-slip sleeve enhances the friction resistance between the landing support frame and the ground, making the drone more stable and less likely to slide during landing. By setting the support pads to be conical, on some soft ground, the conical support pads can penetrate into the soil and provide more solid support to prevent the drone from sinking into the ground or being blown by the wind during landing. By setting the buffer landing rod, connecting plate and support spring, the impact force generated by the landing of the agricultural drone is effectively reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The embodiment of the present application discloses a landing bracket for an agricultural drone. Figure 1-Figure 2 , including an agricultural drone 1, which is equipped with a rotor 2, and a mounting frame 3 is fixed to the bottom of the agricultural drone 1, and fixed blocks 9 are installed on both sides of the inside of the mounting frame 3, and the fixed block 9 is connected to a buffer landing rod 8, and the bottom end of the buffer landing rod 8 is fixedly connected to a landing support frame 4. When the agricultural drone 1 lands and contacts the ground, the landing support frame 4 first contacts the ground to support both sides of the bottom of the mounting frame 3, providing a stable basic support structure for the drone, ensuring that the drone will not tilt or shake at the moment of landing, and ensuring a smooth landing of the drone. Since an anti-slip sleeve 6 is provided on the outside of the bottom end of the landing support frame 4, and the anti-slip sleeve 6 is fixed to the outer wall of the landing support frame 4, the anti-slip sleeve 6 can enhance the friction resistance in contact with the ground, making it difficult for the drone to slide in the landing position, and a number of supporting pads 7 are equidistantly provided on the bottom end of the anti-slip sleeve 6. The supporting pads 7 are set to a cone shape and can be penetrated into the soil, further enhancing the connection stability of the drone and the ground.

[0020] Combine Figure 3 As shown, mounting grooves 5 are provided on both sides of the bottom of the agricultural drone 1, and connecting blocks 10 are welded to the top ends of the fixing block 9 in an integral structure. One end of the connecting block 10 is fixedly connected to the inner wall of the mounting groove 5. The structure is simple and the connection is stable and reliable. The outer walls of both ends of the fixing block 9 are connected to the mounting strips 15 by screws. The end of the buffer landing rod 8 away from the landing support frame 4 is rotatably connected to the mounting strips 15. This rotation design enables the buffer landing rod 8 to be adaptively adjusted according to the direction of the impact force, better disperse the impact force, improve the buffering effect, and reduce damage to the drone.

[0021] In addition, movable holes 11 are opened at the centers of both sides of the fixed block 9. The internal rotation of the movable hole 11 is connected to a support cantilever 14. The end of the support cantilever 14 away from the movable hole 11 is connected to the top of the landing support frame 4. When the agricultural drone 1 lands, there is a certain impact force. At this time, the landing support frame 4 squeezes the buffer landing rod 8 upward, and the support cantilever 14 moves synchronously with the buffer landing rod 8 in the movable hole 11, which can initially absorb part of the impact force and avoid the impact force being directly transmitted to the drone body, thereby protecting the structure of the drone.

[0022] In the present application, a support assembly is provided on the buffer landing rod 8, and the support assembly includes a support spring 13 arranged in the mounting frame 3. A connecting plate 12 is fixed to the outer wall of the top of the buffer landing rod 8. Since the two ends of the support spring 13 are respectively connected to the connecting plate 12 and the inner wall of the mounting groove 5, the support spring 13 is squeezed by the connecting plate 12 to continue to buffer in the mounting groove 5. The support spring 13 can further absorb the remaining impact force and convert the impact force into elastic potential energy through elastic deformation, thereby reducing the impact force generated by the landing of the agricultural drone 1, achieving a good shock absorption effect, protecting the precision equipment and electronic components inside the drone, and extending the service life of the drone.

[0023] The implementation principle of the landing bracket for an agricultural drone in the embodiment of the present application is as follows: during use, when the agricultural drone 1 lands and contacts the ground, the landing support frame 4 will first contact the ground to support the two sides of the bottom of the mounting frame 3, and the anti-slip sleeve 6 can enhance the friction resistance with the ground, and the support pad 7 is set to a cone shape, which can penetrate into the soil and has a good grip effect, further ensuring the stability of the agricultural drone 1 during landing. At the same time, since the agricultural drone 1 has a certain impact force when landing, the landing support frame 4 squeezes the buffer landing rod 8 upward at this time, and then the top of the buffer landing rod 8 rotates and adapts outside the fixed block 9, and squeezes the support spring 13 through the connecting plate 12 to continue buffering in the mounting groove 5, thereby reducing the impact force generated by the landing of the agricultural drone 1 and having a good shock absorption effect.
