[0016] Figure 2 This is a schematic diagram of the UAV structure. DETAILED DESCRIPTION

[0017] A drone-assisted transportation system for tobacco leaf harvesting in hilly areas, such as Figure 1 and Figure 2 As shown, the system is applied to the field of tobacco leaf harvesting technology, including a frame 1 and a UAV 13 for transporting arranged in conjunction with the frame 1. The UAV used in this embodiment is a mature existing technology, and this embodiment does not involve improvements to the UAV itself, but applies the UAV to tobacco leaf harvesting.

[0018] When harvesting tobacco leaves, the harvested tobacco leaves are placed on the frame 1, and the tobacco leaves on the frame 1 are transported out by the drone 13. In this way, the harvesting vehicle only serves to transport within the plot, and its travel range is small; while the drone 13 shuttles between the plot and the transport vehicle to achieve transportation. Therefore, the frame 1 does not need to be too large, which reduces the volume and weight of the frame 1, is more applicable to the plot, and is not easy to be stuck on the ground due to rugged terrain.

[0019] Regarding the frame 1 structure, in this embodiment, a parking board 4 is arranged on the top of the frame 1. The parking board 4 is arranged horizontally. The parking board 4 is used to place the cigarette bag filled with tobacco leaves. The cigarette bag is on the parking board 4 waiting for the transfer drone 13 to transfer it away. Guardrails 8 are arranged on both sides of the parking board 4 to prevent the cigarette bag from sliding off the parking board 4.

[0020] In order to ensure the stability of the frame 1 during driving, a crawler 5 is arranged at the bottom of the frame 1, and a damper 6 is connected between the frame 1 and the crawler 5, and a buffer spring is sleeved on the outer side of the damper 6. By arranging the damper 6 between the frame 1 and the crawler 5, the shock resistance is increased. Compared with the current ordinary crawler 5 vehicle, the shock absorbing device is arranged on the wheel body. This shock absorbing method is simpler and has a better shock absorbing effect. When working, the crawler 5 drives the movement of the frame 1. In order to provide kinetic energy to the crawler 5, a battery 77 is placed on the frame 1. The battery 77 drives the operation of the crawler 5, and the operation of the crawler 5 drives the movement of the frame 1. As for how to control the moving direction of the frame 1, it does not belong to the improvement scope of this embodiment. It only needs to adopt a conventional method, for example, a cab is installed on the frame 1, and the driver drives the vehicle to realize the motion control of the frame 1; or a remote control method is used to realize the control of the moving direction of the frame 1.

[0021] In order to improve the adaptability of the frame 1, the frame 1 includes a left side frame 9 and a right side frame 10, and a left side sleeve ring 11 and a right side sleeve ring 12 are respectively provided on the left side frame 9 and the right side frame 10. A horizontally arranged connecting rod 3 is connected between the left side frame 9 and the right side frame 10, and both ends of the connecting rod 3 are respectively connected to the left side sleeve ring 11 and the right side sleeve ring 12.

[0022] The left sleeve ring 11 is fixedly connected to the connecting rod 3, and the right sleeve ring 12 is detachably connected to the connecting rod 3. Thus, by pushing the connecting rod 3 in the right sleeve ring 12, the wheelbase of the two tracks 5 can be adjusted, and then the width of the frame 1 can be adjusted to adapt to different plots.

[0023] For the convenience of adjusting the left frame 9 and the right frame 10, an electric push rod is connected between the left frame 9 and the right frame 10. The electric push rod is fixed on the left frame 9, and the telescopic end of the electric push rod is connected to the right frame 10. During operation, the electric push rod extends, thereby pushing the right frame 10, causing the right frame 10 to slide relative to the connecting rod 3, increasing the distance between the left frame 9 and the right frame 10, and widening the entire vehicle frame 1; if the vehicle frame 1 needs to be narrowed, only the electric push rod needs to be shortened. After the width of the vehicle frame 1 is adjusted, the right socket ring 12 can be screwed to the connecting rod 3.

[0024] U-shaped receiving boxes 2 are provided on both sides of the vehicle frame 1, and tobacco pouches are placed in the receiving boxes 2. In this embodiment, the tobacco pouch is a mature prior art, and tobacco farmers mostly use tobacco pouches to collect harvested tobacco leaves, and it is in the shape of a cloth bag. The front end face and the upper top face of the receiving box 2 are both open; thus, it is convenient for tobacco farmers to place the harvested tobacco leaves therein.

[0025] To cooperate with the tobacco pouch, a hanging rod 14 is fixedly provided at the bottom of the unmanned aerial vehicle 13, and a hook is connected to the hanging rod 14 for hanging the tobacco pouch.

[0026] During operation, first, the width of the vehicle frame 1 is adjusted. After the adjustment is completed, the storage battery 7 drives the crawler 5 to move, causing the vehicle frame 1 to move in the field; two tobacco farmers stand on both sides of the vehicle frame 1 respectively; the harvested tobacco leaves are placed into the tobacco pouch sleeved on the receiving box 2; when the tobacco pouch is full, the tobacco pouch is placed on the parking plate 4, and when the unmanned aerial vehicle 13 flies over, it can be hung on the hook; at the same time, an empty tobacco pouch is sleeved on the receiving box 2 again. Repeat this process until the tobacco leaf harvesting work is completed.

[0027] The utility model can greatly reduce the difficulty of harvesting tobacco leaves in hilly areas. With the help of the unmanned aerial vehicle 13, it facilitates the transportation of harvested tobacco leaves, reduces the walking distance of the vehicle frame 1, greatly simplifies the structure of the vehicle frame 1, reduces the weight, and is not likely to get stuck when walking in hilly areas. At the same time, the stability is also greatly improved.
