Description

Technical Field

[0001] The utility model belongs to the technical field of topping, and particularly relates to an unmanned aerial vehicle (UAV) topping device. Background Art

[0002] During the management of tobacco leaf planting, it is necessary to top the tobacco leaves, that is, to remove the top of the tobacco plant. By topping, the apical dominance is removed, which is beneficial to the full development and maturity of the middle and upper tobacco leaves; at the same time, it promotes the root development and is beneficial to improving the maturity of the tobacco leaves.

[0003] When topping the tobacco leaves, the conventional method is manual topping, which has a high labor intensity and low efficiency. To solve this problem, there are currently many mechanical topping methods. For example, the patent application with the publication number of CN117530068A discloses a tobacco topping and bud suppressing collection integrated machine, including: a moving mechanism, a topping mechanism, a bud suppressing mechanism, and a collection mechanism; the topping mechanism is fixedly arranged at the front end of the moving mechanism and is used for clamping and cutting the apical bud of the tobacco plant and conveying the cut apical bud of the tobacco plant to the collection mechanism; the bud suppressing mechanism is fixedly arranged at the rear end of the moving mechanism and is used for spraying a bud suppressing agent on the tobacco plant after cutting the apical bud of the tobacco plant; the moving mechanism is used for carrying the topping mechanism, the bud suppressing mechanism, and the collection mechanism to move. The tobacco topping and bud suppressing collection integrated machine provided by this application can realize efficient topping and bud suppressing operations with less damage to the top tobacco leaves of the tobacco plant.

[0004] This method does not require manual operation and has a low labor intensity. However, when using this method for topping, it is greatly affected by the terrain conditions; at the same time, when walking in the tobacco field, it has relatively high requirements for the row spacing of the tobacco field.

[0005] Therefore, a topping mechanism with less requirements for terrain conditions and the conditions of the tobacco field itself is needed. Summary of the Invention

[0022] The drone topping device can achieve topping of tobacco leaves through this topping device. This device is as Figures 1-2 shown, including a drone 1, a lifting component, a windshield 3, and a topping component 4.

[0023] In this embodiment, the lifting component drives the topping component 4 to lift and lower, so that the distance between the drone and the topping component can be adjusted as needed, reducing the impact on the tobacco leaves during the process of the drone flapping the air flow.

[0024] This embodiment is applicable to drones 1 with relatively large power. This type of drone 1 has relatively strong wind power during flight. When approaching the tobacco leaves, it is easy to cause damage to the tobacco leaves due to excessive wind power. If the air flow of the drone has no impact on the tobacco leaves, the lifting device is directly retracted to the shortest length. If there is an impact, the length of the lifting device is adjusted as needed. The length of the lifting device should be such that it can blow the tobacco leaves away without causing damage during flight.

[0025] In this embodiment, by setting a lifting component, the topping component 4 is lowered to reduce the impact of the wind power during the flight of the drone 1 on the tobacco leaves.

[0026] Among them, the lifting component is connected to the bottom of the drone 1. As Figure 3 shown, the lifting component includes a lifting scissor frame 2. The lifting scissor frame 2 includes two upper scissor rods 5 and two lower scissor rods 11; the two upper scissor rods 5 are relatively rotatably arranged; the two lower scissor rods 11 are also relatively rotatably arranged.

[0027] An upper slide rail 7 is provided at the bottom of the drone 1 along the length direction of the drone 1. An upper slider is slidably provided on the upper slide rail 7. One of the two upper scissor rods 5 is fixedly connected to the bottom of the drone 1, and the other is connected to the upper slider; an electric push rod 8 is provided at the bottom of the drone 1, and the telescopic end of the electric push rod 8 is connected to the upper slider.

[0028] A lower slide rail 9 is provided on the windshield 3. A lower slider 10 is slidably provided on the lower slide rail 9. One of the two lower scissor rods 11 is fixedly connected to the lower slider 10, and the other is fixedly connected to the top of the windshield 3. As an alternative to this embodiment, to ensure the strength of the windshield 3, a frame 12 is provided at the top of the windshield 3. Among them, the lower slide rail 9 is connected to the frame 12; one of the two lower scissor rods 11 is connected to the frame 12, and the other is connected to the lower slider 10.

[0029] During operation, the electric push rod 8 drives the upper slider to slide on the upper slide rail 7, and the lower slider 10 also slides along the lower slide rail 9 under the action, so that the lifting scissors frame 2 extends or shortens, and then the lifting of the lifting scissors frame 2 is realized. In this way, the lifting is convenient and the stability is higher. Of course, as an alternative to this embodiment, the lifting component can also directly use an electric telescopic rod, and the lifting of the topping component 4 can be realized through the electric telescopic rod.

[0030] The windshield 3 is located below the topping component 4, and the windshield 3 is used to further weaken the wind generated by the unmanned aerial vehicle 1 and reduce its impact on the tobacco leaves.

[0031] The windshield 3 arches upward from the outside to the inside, that is, the middle part of the windshield 3 bulges, so as to realize the wind blowing to both sides; a horizontally arranged reinforcing rod is connected to the lower part of the windshield 3, and the arranged reinforcing rod can improve the strength of the windshield 3.

[0032] Ventilation grilles 13 are provided at the edge of the windshield 3. Through the ventilation grilles 13, the airflow brought by the unmanned aerial vehicle 1 can enter below the windshield 3, thereby blowing the tobacco leaves so that the tobacco leaf tops leak out. In this embodiment, the ventilation grilles 13 are in an arc shape inclined outward, so that the airflow can evenly enter below the windshield 3 through the ventilation grilles 13 and blow the tobacco leaves.

[0033] In this embodiment, the lifting of the lifting component can be realized according to the magnitude of the airflow blown by the unmanned aerial vehicle 1. Thus, on the one hand, the wind entering the windshield 3 from the edge of the windshield 3 will not be too strong to blow the tobacco leaves off, and on the other hand, it can blow the tobacco leaves so that the tobacco leaf tops leak out, facilitating topping.

[0034] There are two topping components 4 in total. Both of the two topping components 4 are arranged below the windshield 3. For the convenience of installing the topping components 4, two mounting brackets 14 are provided at the lower part of the windshield 3, and the two topping components 4 are respectively arranged on the two mounting brackets 14.

[0035] Among them, the mounting bracket 14 is arranged to incline downward; as Figure 4 shown, the topping component 4 includes a rotating disk 16 and a motor 15. The motor 15 drives the rotating disk 16 to rotate, and cutter teeth are evenly distributed on the edge of the rotating disk 16. Among them, the way the motor 15 drives the rotating disk 16 is that a primary gear 19 is connected to the output shaft of the motor 15, a secondary gear is connected to the rotating disk 16, and a transmission chain 18 is arranged between the primary gear 19 and the secondary gear. Through the transmission chain 18, the motor 15 drives the rotating disk 16 to rotate.

[0036] The topping knife is connected to the bottom end of the lifting component, and the topping component 4 is installed on the lifting component; the projections of the edges of the topping component 4 in the horizontal direction coincide; the rotation directions of the two rotating disks 16 are opposite. At the same time, both of the two rotating disks 16 are inclined downward and inward, driving the rotation of the rotating disks 16, and the tobacco leaves are topped off during the rotation of the cutter teeth.

[0037] In order to facilitate the entry of tobacco leaves into the space between the topping components 4, guide rods 17 are provided at the lower parts of the two mounting brackets 14, and a gap is reserved between the two guide rods 17. The width of the gap gradually decreases from front to back first and then remains unchanged, and the width of the gap below the rotating disk 16 is the smallest. The tobacco plant enters the gap. During the forward flight of the UAV 1, the gap becomes smaller and smaller, and finally enters the position of the rotating disk 16. During the rotation of the rotating disk 16, the tobacco leaf top is sucked between the two rotating disks 16, and the tobacco leaf top is topped off during the rotation of the rotating disk 16, achieving the purpose of topping the tobacco leaves. The topped-off tobacco leaf tops fall into the tobacco field.

[0038] The working process is as follows: The UAV 1 flies into the tobacco field to be topped. According to the magnitude of the wind blown by the UAV 1 and the height of the tobacco plants, the lifting component is adjusted so that the wind blown by the UAV 1 will not damage the tobacco leaves; the UAV 1 flies above the tobacco plants, and the tobacco rod enters the gap between the two guide rods 17; the airflow blown by the UAV 1 flows downward from the middle of the windshield 3 and enters below the windshield 3 from the ventilation grille 13, thereby blowing the tobacco leaves to expose the tobacco leaf tops, and the tobacco leaf tops are topped off during the rotation of the rotating disk 16.

[0039] The utility model discloses a UAV topping device, which can adjust the distance between the UAV 1 and the tobacco leaf top as needed, so as to achieve UAV 1 topping under the condition of reducing damage to the tobacco leaves. The implementation is convenient, not affected by the field conditions, and the tobacco leaves can be topped flexibly.
