Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco topping, and particularly relates to an airborne tobacco topping system based on an aircraft. Background Art

[0002] Mountainous areas are the main tobacco production areas in the country. The ecological conditions in mountainous tobacco-growing areas vary greatly, and the characteristics of three-dimensional climate are obvious, showing the phenomenon of "four seasons within one mountain and different weathers within ten miles". Therefore, mountainous tobacco can not only meet the needs of the cigarette industry in terms of quantity, but also meet the requirements of the cigarette industry with different characteristic aroma qualities.

[0003] Currently, due to the uneven terrain in mountainous areas, the use of mechanization is limited, and manual labor is mainly relied on.

[0004] During the entire tobacco planting process, tobacco topping is very important and needs to be carried out on each tobacco plant one by one, otherwise it will affect the growth of tobacco. Currently, the degree of mechanization of tobacco topping is relatively high. The patent application with the publication number CN 117694124 A discloses a crawler-type tobacco topping machine and a topping method. The topping machine includes a frame, a traveling mechanism, a topping mechanism and a bud inhibitor spraying mechanism arranged in sequence from front to back along the traveling direction of the frame; the traveling mechanism is located at the bottom of the frame; a passage gap is provided in the middle of the frame, and the topping mechanism is located in the middle of the passage gap; the topping mechanism includes a pressing plate and a knife rod rotatably arranged above the pressing plate. A tobacco rod gap is provided on the pressing plate. A topping knife is connected to the bottom of the knife rod. A wing plate connected to the knife rod is provided above the topping knife, and a collection box connected to the frame is provided on the side of the topping knife. The tobacco topping machine described in the present invention realizes the topping of tobacco rods and bud inhibition as the frame travels, reduces the labor intensity of topping, and at the same time, causes little damage to tobacco plants and is not likely to miss any tobacco tops. The structure is simple and easy to use, and only one person is required to operate the work of the frame.

[0005] As it travels, topping and bud inhibition are carried out simultaneously, and the overall speed is relatively fast. However, this method is suitable for use in plain areas. If used in hilly areas, the vehicle is heavy, the seismic resistance is not strong, the vehicle jolts greatly, and it is not stable enough to use.

[0006] Therefore, a tobacco topping vehicle that can be used in hilly areas is needed. Summary of the Invention

[0026] Embodiment 1. Based on the airborne tobacco topping system, this device is applicable to hilly areas where the terrain is uneven and the road surface is relatively rough. Ordinary mechanical vehicles will be unstable when driving on it.

[0027] As Figure 1 and Figure 2 shown, this system includes a vehicle frame 1, a topping drone 8, a spraying drone, and a transfer drone. The vehicle frame 1 moves, the topping drone 8 tops, and the topped tobacco leaf tops are knocked into the vehicle frame 1; the spraying drone sprays the bud inhibitor on the tobacco leaf stalks after topping; the transfer drone transfers the topped tobacco leaf tops out.

[0028] Regarding the structure of the frame 1, in this embodiment, a parking plate 4 is provided at the top of the frame 1. The parking plate 4 is horizontally arranged and is used to place the tobacco pouches filled with the tops of tobacco leaves. The tobacco pouches wait on the parking plate 4 for the transfer drone to transfer them away. To ensure the stability of the frame 1 during driving, a crawler 5 is provided at the bottom of the frame 1. A damper 14 is connected between the frame 1 and the crawler 5, and a buffer spring is sleeved outside the damper 14. By providing the damper 14 between the frame 1 and the crawler 5, the seismic resistance is increased. Compared with the current ordinary crawler vehicles, which are provided with shock-absorbing devices on the wheels, this shock-absorbing method is simpler and the shock-absorbing effect is also better. During operation, the crawler 5 drives the movement of the frame 1. To provide kinetic energy for the crawler 5, a storage battery 7 is placed on the frame 1. The storage battery 7 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 vehicle frame 1, whether it is manually driven or by remote control does not fall within the scope of modification of this application and can be achieved through conventional means. For example, a conventional cab can be installed on the frame 1 to realize the movement of the frame 1 through the cab, or the movement of the frame 1 can be realized by remote control.

[0029] In this embodiment, by using drones for transfer, spraying of sprout inhibitors, and topping, the requirements for mechanical vehicles in rough hilly areas are greatly reduced, the weight of the frame 1 is reduced, and the applicable range of the frame 1 is increased. In this embodiment, the frame 1 only functions to load the topped tobacco leaves and sprout inhibitors. At the same time, the structure of the frame 1 is simpler, the weight can be greatly reduced, and it is not easily stuck on the ground due to rough terrain and unable to move.

[0030] To cooperate with the spraying drone, a container 6 is provided on the frame 1. This container can be used to hold the sprout inhibitor liquid. A water pump is provided inside the container 6. The water outlet of the water pump is connected to a water outlet pipe 18, and a male head 21 of a quick connector is connected to the water outlet pipe 18; a water suction pipe 19 is provided on the spraying drone, and a female head 22 of a quick connector is connected to the water suction pipe 19. This female head 22 cooperates with the male head 21 on the water outlet pipe 18, and the two can be quickly connected to improve the water suction speed of the spraying drone. In this embodiment, the quick connector is a mature commercially available product and can be directly purchased. The quick connector used in the implementation process is purchased from the store of 1688 Yongkang Fancultivation Tools Co., Ltd., and the used model is the SP30+PP30 quick connector. This model of quick connector includes the female head 22 and the male head 21. PU pipes with an outer diameter of 10 mm and an inner diameter of 6.5 mm are connected to both the female head 22 and the male head 21. That is, the water outlet pipe 18 connected to the water pump and the water suction pipe 19 connected to the drone both use PU pipes.

[0031] With the help of personnel, the male head 21 of the quick connector on the water pump and the female head 22 of the quick connector on the drone can be quickly combined, so that the water pump can quickly fill the water tank 20 of the drone without affecting the spraying efficiency.

[0032] In Figure 1 there is no water pipe 18 and quick connector shown on the container 6; meanwhile, there is also no spraying drone shown in this embodiment. For the sake of easy understanding of the connection between the container 6 and the water tank 20 on the drone, reference can be made to Figure 3 for understanding. In Figure 3 only the water tank 20 of the drone is drawn, and other components are not drawn. There is no improvement involved, and the improvement point lies only in connecting a quick connector to the suction pipe 19 of the drone.

[0033] In this embodiment, the spraying drone is a mature commercially available product. For example, the drone used for spraying pesticides has the same structure. This embodiment does not involve the improvement of the spraying drone; only the container 6 is placed on the movable vehicle frame 1. In this way, when topping and spraying the bud inhibitor at the same time, when the liquid in the spraying drone is insufficient, there is no need to drive to the field head to add the bud inhibitor, and the addition of the bud inhibitor can be directly realized inside the plot, with fast implementation and low power consumption.

[0034] When there is a spraying drone for spraying the bud inhibitor liquid, the quick connector on the spraying drone can be connected to the quick connector on the suction pipe 19. The bud inhibitor liquid enters the water tank 20 of the spraying drone from the container 6. There is a water tank 20 and a spray head on the spraying drone. The water tank 20 is connected to the suction pipe 19, and the water in the water tank 20 is sprayed out from the spray head. In this embodiment, the setting of the water tank and the spray head on the drone are both mature existing technologies. For example, the existing drones for spraying pesticides. This embodiment does not involve the improvement of this part.

[0035] To cooperate with topping, the topping drone 8 includes four flapping impellers 9 which are rotatably arranged. The flapping impellers 9 themselves are common structures on the drone. The reason for writing them out in this embodiment is that they will be used later.

[0036] There is a rotatably arranged rotating shaft 10 on the bottom surface of the topping drone 8. The bottom end of the rotating shaft 10 is connected with a cutting part. The cutting part includes a disc 12. Saw teeth 13 are evenly distributed on the circumference of the disc 12. By rotating the disc 12, the saw teeth 13 are driven to rotate, so as to knock down the tobacco leaf tops. At the same time, a plurality of guide vanes 11 are arranged on the rotating shaft 10. The guide vanes 11 are vertically arranged, and the plurality of guide vanes 11 are evenly connected to the rotating shaft 10 along the circumference of the rotating shaft 10.

[0037] On the vehicle frame 1, a receiving box 2 is arranged in cooperation with the rotating shaft 10. The number of the receiving boxes 2 is two, and the two receiving boxes 2 are respectively located on the lower sides of the cutting parts, so as to prevent the knocked-down tobacco leaf tops from passing over the receiving boxes 2 and falling to the ground. A baffle 3 is arranged outside the receiving box 2, and the baffle 3 is used to prevent the tobacco leaf tops from passing over the receiving box and falling to the ground. There is a gap above the side of the receiving box 2, and the topping drone 8 is located in the gap. When in use, the topping drone and the vehicle frame 1 walk synchronously.

[0038] The provided guide vane 11 rotates together with the rotating shaft 10, thus pushing the knocked-down tobacco leaves to the side and then falling into the receiving box 2. When rotating forward, they fall into the left receiving box 2, and when rotating reversely, they fall into the right receiving box 2.

[0039] When in use, a tobacco bag can be sleeved inside the receiving box 2. The tobacco bag is a cloth bag commonly used at present to hold tobacco leaves or the knocked-down tobacco leaf tops. After the tobacco bag is full, it is manually placed on the parking plate 4. When the transfer drone flies over, it can be hung on the transfer drone. At present, using drones for transfer is a mature existing technology, and this embodiment does not improve the transfer drone, but only applies it to this embodiment.

[0040] The topping drone 8 moves synchronously with the frame 1. The topping drone 8 is always located above the sides of the two receiving boxes of the frame 1, and the vertical distance between the topping drone 8 and the receiving box 2 always remains the same. During the topping process, the topping drone 8 knocks the knocked-down tobacco leaves into the receiving box 2. Since the flight speed and height of the drone are adjustable, and at the same time the moving speed of the frame 1 is also adjustable, during use, only the flight speed and height of the drone need to be adjusted to keep it consistent with the frame 1.

[0041] Embodiment 2, the difference between this embodiment and Embodiment 1 is that: as Figure 4 shown, above the sides of the two receiving boxes 2, a connecting frame for cooperating with the drone is provided, and the linear distances from the connecting frame to the two receiving boxes 2 are equal.

[0042] Among them, the connecting frame includes a horizontally arranged connecting shaft 15, and a connecting hole is provided on the connecting shaft 15. The drone is connected to the connecting hole.

[0043] At the same time, the connecting frame further includes an L-shaped connecting plate connected to the lower surface of the connecting shaft 15. The connecting plate includes a vertically arranged vertical plate and a horizontal plate 16 connected to the vertical plate. A guiding groove 17 is formed on the horizontal plate 16, and the width of the guiding groove 17 gradually decreases from the edge of the horizontal plate 16 towards the inner side of the horizontal plate 16 and then remains unchanged.

[0044] The difference between Embodiment 1 and Embodiment 2 is that in Embodiment 1, the topping drone is located inside the gap of the frame and is not connected to the frame, but only keeps synchronous actions with the frame 1 all the time. While in Embodiment 2, the topping drone is connected to the frame.

[0045] When working, the drone follows the movement of the vehicle frame 1 and keeps in sync with it. When the drone rotates, the impeller 9 flaps to blow away the tobacco leaves at the top of the tobacco stalk, thus exposing the top of the tobacco leaves. Then the rotating shaft 10 rotates, and the saw teeth 13 on the disc 12 knock off the top of the tobacco leaves as the rotating shaft 10 rotates. The knocked-off top of the tobacco leaves, under the action of the guide vane 11, is knocked into the tobacco pocket in the receiving box 2. When a tobacco pocket is full, the rotation direction of the rotating shaft 10 of the drone changes, and it knocks the top of the tobacco leaves into the net pocket of another receiving box 2. At the same time, the full tobacco pocket is placed on the parking plate 4, and a new tobacco pocket is put into this receiving box 2; after the drone flies over, it can transfer away the tobacco pocket.

[0046] When the battery power of the drone is insufficient, the drone is connected to the connecting frame, thereby reducing the power consumption of the drone. The impeller 9 and the rotating shaft 10 on the connecting frame of the drone are still in the working state. On the one hand, the impeller 9 ensures that the tobacco leaves are blown away. On the other hand, the rotation of the rotating shaft 10 drives the rotation of the disc 12, thereby knocking off the top of the tobacco leaves.

[0047] The utility model is easy to implement. By combining the drone and the vehicle frame 1, it facilitates the process of topping the tobacco leaves. At the same time, the drone transfers away the top of the tobacco leaves and sprays the bud inhibitor. It is not affected by the terrain and is suitable for hilly areas; in addition, the set caterpillar track 5 has a novel structure and improves the stability of the overall vehicle frame 1.
