Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides an embodiment of a mounting mechanism for an agricultural drone, including a plate 3, a connecting component mounted on the plate 3, a connecting block 1 disposed below the plate 3, a storage box 11 disposed at the bottom of the connecting block 1, the connecting component being fixedly connected to the connecting block 1, the connecting component also including a positioning part for positioning the plate 3 and the connecting block 1, a U-shaped block 31 mounted on the top of the plate 3, the U-shaped block 31 including a U-shaped opening, the landing gear of the drone being fitted into the U-shaped opening, the connecting component facilitating the mounting of the connecting block 1 below, achieving the effect of the drone moving together with the storage box 11, the positioning part being able to better determine the relative position of the plate 3 and the connecting block 1, making the connection smoother and reducing the difficulty of alignment, the cooperation between the U-shaped block 31 and the plate 3 can clamp and fix the landing gear of the drone, making the drone and the plate 3 connected as a whole.

[0024] For a first embodiment of the connection component, please refer to Figure 1-2 A further solution based on this embodiment is as follows: the connecting component includes a motor 33, a stud 2 is sleeved on the output shaft of the motor 33, and a screw hole 10 is provided at the middle position of the top of the connecting block 1. The stud 2 can pass through the plate 3 and connect with the screw hole 10. The motor 33, which can be powered off and braked, can easily drive the stud 2 to engage with the screw hole 10 at the top of the connecting block 1, thereby achieving the mounting effect of the connecting block 1. The motor 33 can be powered off and braked, so that continuous power supply to the motor 33 can be avoided when mounting.

[0025] Please see Figure 2-3 A further solution based on this embodiment is as follows: A movable plate 32 is installed at the bottom of the motor 33, and a guide rod 321 is installed at the bottom of the movable plate 32. A guide hole 30 matching the guide rod 321 is passed through the plate 3. A limit baffle 322 is connected to the bottom of the guide rod 321. A flat spring 3211 is sleeved in the interval between the guide rod 321 and the plate 321 and the limit baffle 322. A circular plate 21 is integrally formed on the top of the stud 2. The circular plate 21 is provided with a hole 2 corresponding to the output shaft of the motor 33. 10. The top of plate 3 is provided with a circular groove 35 for accommodating the circular plate 21. Through the cooperation of guide rod 321, flat spring 3211 and limiting baffle 322, the movable plate 32 can drive motor 33 to move upward. When the stud 2 is subjected to axial impact, the impact force can be prevented from being transmitted to the output shaft of motor 33, thus extending the service life of motor 33. The diameter of hole 210 is slightly larger than the diameter of output shaft of motor 33, so that hole 210 can be fitted around the outer diameter of output shaft of motor 33 and move up and down.

[0026] Please see Figure 2-3 A further solution based on this embodiment is as follows: The positioning part includes a positioning rod 34 disposed at the bottom of the plate 3. The top of the connecting block 1 is provided with a positioning hole 12 corresponding to the positioning rod 34. The upper edge of the positioning hole 12 is provided with a chamfer 121. The positioning rod 34 facilitates the accurate insertion of the stud 2 into the screw hole 10, increasing the accuracy of alignment. The chamfer 121 on the upper edge of the positioning hole 12 increases the fault tolerance of alignment, allowing the positioning rod 34 to slide down into the positioning hole 12 along the chamfer 121. When the device is mounted, the cooperation between the positioning rod 34 and the positioning hole 12 can effectively prevent the connecting block 1 from rotating around the stud 2 in the air, avoiding the situation where the connecting block 1 and the storage box 11 fall from the air together.

[0027] For a second embodiment of the connection component, please refer to [link / reference]. Figure 4-5A further solution based on this embodiment is as follows: The connecting assembly includes two fixed end blocks 45 disposed on the top of plate 1 3. A bidirectional screw 452 is rotatably connected between the two fixed end blocks 45. A motor 2 451 capable of driving the bidirectional screw 452 to rotate is installed on the side of one of the fixed end blocks 45 away from the bidirectional screw 452. Moving blocks 44 are respectively meshed on both sides of the bidirectional screw 452. A plate 3 43 is provided at the bottom of the moving block 44. A plate 5 42 is provided at the bottom of the plate 3 43. The middle area of ​​the bottom of plate 1 3 can fit against the top of the connecting block 1. A positioning part is provided on the side of plate 5 42 facing the connecting block 1. The positioning part includes a plate 41 fixedly connected to plate 5 42. The bidirectional screw 452 facilitates the moving blocks 44 to move towards each other. The motor 2 451 can be de-energized and braked to reduce the continuous power supply to the motor 2 451. The moving blocks 44 drive the plate 41 to form a fixed effect on the connecting block 1, so that the connecting assembly can form a mounting effect on the connecting block 1.

[0028] Please see Figure 4-5 A further solution based on this embodiment is as follows: the side wall of the connecting block 1 is provided with a positioning groove 13 corresponding to the plate 41. The side of the plate 41 facing the connecting block 1 is provided with a rounded corner 411. The positioning groove 13 allows the plate 41 to be inserted into it, increasing the stability of the connecting block 1 and reducing the possibility of the connecting block 1 falling in the air. The rounded corner 411 on the plate 41 facilitates the insertion and alignment of the plate 41, increasing the convenience of alignment. The cooperation between the plate 41 and the positioning groove 13 can achieve the effect of hanging the connecting block 1 and also achieve the effect of positioning the connecting block 1.

[0029] Please see Figure 4-5 A further solution based on this embodiment is as follows: sliding grooves 401 are provided on the left and right sides of the first plate 3. The bottom of the sliding groove 401 is provided with a second clearance position 403. The distance between the front and rear sides of the sliding groove 401 is greater than the distance between the front and rear sides of the second clearance position 403. The height of the sliding groove 401 corresponds to the height of the third plate 43. The sliding groove 401 facilitates the sliding of the third plate 43 inside. The sliding groove 401 and the third plate 43 are fitted with a clearance to increase the stability of the third plate 43 in the sliding groove 401. While reducing shaking, it is also convenient for the moving block 44 to drag the third plate 43 to move. The moving block 44 and the third plate 43 are connected by screws.

[0030] Please see Figure 5 A further solution based on this embodiment is as follows: above the sliding groove 401, there is also a clearance position 402 for the moving block 44. The distance between the front and rear sides of the clearance position 402 is smaller than the distance between the front and rear sides of the sliding groove 401. The clearance position 402 can effectively avoid the moving block 44, reducing the risk of interference. The distance between the front and rear sides of the clearance position 402 is smaller than the distance between the front and rear sides of the sliding groove 401, which can increase the stability of the plate 43 in the sliding groove 401.

[0031] Working principle: In the first embodiment of the connecting component, the drone drives plate 3 to fly above the connecting block 1, and then remotely controls the drone to descend. During descent, some swaying may occur. Thanks to the structure of the chamfer 121, even if the positioning rod 34 has a slight deviation in position, it can still fall into the positioning hole 12 along the chamfer 121. When the positioning rod 34 falls into the positioning hole 12, the axis of the stud 2 can coincide with the axis of the screw hole 10. At this time, the drone continues to fall, the stud 2 and the screw hole 10 are in contact, and then the motor 33 is driven by electricity. This allows the stud 2 to engage with the screw hole 10, thus completing the mounting of the connecting block 1. Subsequently, the power to motor 33 is cut off, and the internal brake of motor 33 locks. If stud 2 is accidentally impacted axially, it will move upwards, and the circular plate 21 will push against the movable plate 32, causing the movable plate 32 to jump upwards. The flat spring 3211 can alleviate this axial impact force. The diameter of the hole 210 is larger than the diameter of the output shaft of motor 33, thus preventing the output shaft of motor 33 from being impacted and extending the service life of motor 33. This is especially important when the drone stops flying. When the bottom of the positioning rod 34 is in contact with the ground, in the second embodiment of the connecting assembly, the drone drives the plate 3 to fly above the connecting block 1, and then remotely controls the drone to descend. When the bottom of the plate 3 is in contact with the top of the connecting block 1, the motor 451 is energized and drives the bidirectional screw 452 to rotate, causing the two moving blocks 44 to move closer to each other, so that the plate 41 is inserted into the positioning groove 13. The positioning groove 13 is provided with rounded corners 411, so that the plate 41 can also be inserted when the drone's landing parameters are offset by a certain amount. To increase applicability, when plate 41 is fully inserted into positioning slot 13, motor 2 451 is de-energized and its brake locks to prevent the bidirectional screw 452 from rotating. This completes the mounting operation. The power for motor 2 451 and motor 1 33 is taken from the drone's battery. The drone, motor 2 451, and motor 1 33 are all existing technologies, and their working principles will not be elaborated here. The drone also includes a landing gear below, which is made of spliced ​​rods. U-shaped block 31 can wrap the landing gear rods and is connected to plate 1 3 by screws.
