A plurality of conveyor rollers 10 for tensioning and supporting the conveyor belt 5 are sleeved on the inner wall of the conveyor belt 5. The two ends of the conveyor rollers 10 are rotatably connected to the two fixed frames 4. A controller 18 is installed on the side wall of the base box 1. A battery 12 is installed inside the base box 1. A drive mechanism for driving the conveyor rollers 10 at the end of the conveyor belt 5 to rotate, thereby rotating the conveyor belt 5, is provided on the fixed frames 4 and the base box 1. A fixing mechanism for clamping and fixing the conveyor belt 5 during transportation is provided on the upper end of the base box 1.

[0025] The driving mechanism includes a motor 19. An opening 11 is provided at the upper end of the base box 1 inside the fixed frame 4. One end of the conveyor roller 10 at the end of the conveyor belt 5 passes through the side wall of the fixed frame 4 and is equipped with a first gear 7. The first gear 7 is located inside the fixed frame 4. The motor 19 is installed on the top of the base box 1. A second gear 8 that works with the first gear 7 is installed at the output end of the motor 19. The upper end of the second gear 8 passes through the opening 11 and meshes with the first gear 7.

[0026] During unloading, the controller 18 controls the motor 19 to start. The output of the motor 19 drives the second gear 8 to rotate, the second gear 8 drives the first gear 7 to rotate, the first gear 7 drives the conveyor roller 10 to rotate, and the conveyor roller 10 drives the conveyor belt 5 to rotate, thereby enabling the conveyor belt 5 to transport the goods to the gate of the fence 2, realizing automatic unloading.

[0027] The fixing mechanism includes several stop bars 9, which are disposed inside the conveyor belt 5. The stop bars 9 are horizontally disposed between two adjacent conveyor rollers 10. The two ends of the stop bars 9 are mounted on the side walls of two fixing frames 4. Several limiting cylinders 13 are installed on the upper end of the base box 1 directly below the stop bars 9. Clamping columns 17, which cooperate with the stop bars 9 to clamp and fix the conveyor belt 5, are slidably connected to the inner wall of the limiting cylinders 13. A mounting plate 16 is horizontally mounted on the lower end of the clamping column 17. A tension spring 20 is installed on the lower end of the mounting plate 16 to pull the mounting plate 16 and the clamping column 17 away from the stop bars 9. The lower end of the tension spring 20 is installed at the bottom of the base box 1. A moving component is provided inside the base box 1 to push the mounting plate 16 and the clamping column 17 upward to clamp and fix the conveyor belt 5.

[0028] The moving component includes an electric push rod 15, which is horizontally mounted at the bottom of the base box 1. A first moving plate 14 is vertically mounted at the output end of the electric push rod 15. Several second moving plates 21 are horizontally mounted on the lower end of the side wall of the first moving plate 14 away from the electric push rod 15. The second moving plates 21 are perpendicular to the first moving plate 14. The second moving plates 21 are staggered with the tension spring 20. The second moving plates 21 are located directly below the mounting plate 16. Several second guide inclined blocks 22 are mounted on the upper end of the second moving plates 21. A first guide inclined block 6 that cooperates with the second guide inclined blocks 22 is mounted on the lower end of the mounting plate 16. The inclined surfaces of the first guide inclined block 6 and the second guide inclined block 22 are in contact with each other.

[0029] When clamping and fixing the conveyor belt 5, the controller 18 controls the electric push rod 15 to extend. The output end of the electric push rod 15 pushes the first moving plate 14 to move. The first moving plate 14 drives the second moving plate 21 to move. The second moving plate 21 drives the second guide inclined block 22 to move. Under the action of the inclined plane, the second guide inclined block 22 pushes the first guide inclined block 6 to move upward. The first guide inclined block 6 drives the mounting plate 16 to move upward and stretches the tension spring 20. The mounting plate 16 drives the clamping column 17 to move upward along the inner wall of the limiting cylinder 13. The clamping column 17 squeezes and fixes the conveyor belt 5 on the stop bar 9, thereby realizing the fixing of the conveyor belt 5.

[0030] When the clamping and fixing of the conveyor belt 5 is released, the controller 18 controls the electric push rod 15 to retract. The output end of the electric push rod 15 drives the first moving plate 14, the second moving plate 21, and the second guide inclined block 22 to move, so that the second guide inclined block 22 moves away from the first guide inclined block 6. Under the action of the elastic force, the tension spring 20 pulls the mounting plate 16 to move downward. The mounting plate 16 drives the clamping column 17 to move downward along the inner wall of the limiting cylinder 13, thereby releasing the clamping and fixing of the conveyor belt 5.

[0031] The working principle of a self-unloading drone for transporting cargo frames:

[0032] During loading and hoisting, the controller 18 controls the extension of the electric push rod 15. The output end of the electric push rod 15 pushes the first moving plate 14 to move. The first moving plate 14 drives the second moving plate 21 to move. The second moving plate 21 drives the second guide inclined block 22 to move. Under the action of the inclined plane, the second guide inclined block 22 pushes the first guide inclined block 6 to move upward. The first guide inclined block 6 drives the mounting plate 16 to move upward and stretches the tension spring 20. The mounting plate 16 drives the clamping column 17 to move upward along the inner wall of the limiting cylinder 13. The clamping column 17 squeezes and fixes the conveyor belt 5 to the stop bar 9, thereby realizing the fixation of the conveyor belt 5.

[0033] During unloading, the controller 18 controls the electric push rod 15 to retract. The output end of the electric push rod 15 drives the first moving plate 14, the second moving plate 21, and the second guide inclined block 22 to move, so that the second guide inclined block 22 moves away from the first guide inclined block 6. Under the action of the elastic force, the tension spring 20 pulls the mounting plate 16 to move downward. The mounting plate 16 drives the clamping column 17 to move downward along the inner wall of the limiting cylinder 13, thereby releasing the clamping and fixing of the conveyor belt 5.

[0034] Then, the controller 18 controls the motor 19 to start. The output of the motor 19 drives the second gear 8 to rotate, the second gear 8 drives the first gear 7 to rotate, the first gear 7 drives the conveyor roller 10 to rotate, and the conveyor roller 10 drives the conveyor belt 5 to rotate, so that the conveyor belt 5 transports the goods to the gate of the fence 2, realizing automatic unloading.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
