Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco leaf harvesting, and particularly relates to an upper tobacco leaf harvesting device based on an unmanned aerial vehicle (UAV). Background Art

[0002] After tobacco leaves are mature, the tobacco leaves on the tobacco plants need to be harvested and then subjected to subsequent processing, and finally used for making cigarettes. The conventional method for harvesting tobacco leaves is manual harvesting, which has a high labor intensity. At present, there are many solutions for harvesting tobacco leaves by mechanical means. For example, the patent application with the publication number of CN118077418A discloses a fresh tobacco leaf picking device and its working method. The fresh tobacco leaf picking device is characterized in that it includes a gantry-shaped frame and wheels arranged at the lower bottoms on both sides of the gantry-shaped frame and capable of traveling along the ridges between fields. Two sets of symmetrically arranged lifting seats are installed on the gantry-shaped frame, and two sets of harvesting mechanisms are respectively installed on the lifting seats. The lifting seats are driven to lift by a lifting drive mechanism installed on the gantry-shaped frame. The harvesting mechanism includes a picking mechanism and a collecting mechanism. According to the maturity law of tobacco leaves, at different growth stages of tobacco leaves, starting from the bottom, the picking mechanism and the collecting mechanism can be fixed at different starting picking heights through the lifting drive mechanism to achieve layered picking; by controlling the upward movement stroke of the semi-circular knife, quantitative picking of tobacco leaves on the basis of layering can be achieved; since the semi-circular knife always keeps a hugging state with the tobacco plant during the picking process, the omission of cutting tobacco leaves can be avoided.

[0003] Although this mechanical tobacco leaf harvesting method can greatly improve the tobacco leaf harvesting speed, during the harvesting process, it is easy to miss the upper tobacco leaves, and it is necessary to manually pick the upper tobacco leaves again. Here, the upper part refers to the tobacco leaves at the top of the tobacco plant, which are often two symmetric tobacco leaves. Although the intensity of manually picking the upper tobacco leaves is greatly reduced, the efficiency is still low. Workers need to walk back and forth in the tobacco field to achieve picking. Therefore, a device capable of harvesting upper tobacco leaves is needed to improve the efficiency of tobacco leaf harvesting. Summary of the Invention

[0026] During operation, the electric push rod 10 pushes the upper slider to move on the upper slide rail 9, thereby driving the upper scissors rod 8 to move on the upper slide rail 9, and further realizing the lifting of the lifting scissors frame 2; the lifting of the lifting scissors frame 2 drives the plate beater 3 to lift. During the process of the plate beater 3 descending, the upper leaves of the tobacco plants are folded off and dropped into the tobacco leaf collection box 5, realizing the harvesting and collection of tobacco leaves.

[0027] In this embodiment, the number of the tobacco leaf collection boxes 5 is two.

During implementation, the two guiding plates 7 are respectively connected to the two tobacco leaf collection boxes 5.

[0030] Embodiment 2, the difference between this embodiment and Embodiment 1 is that: a collection camera 151 is provided on the unmanned aerial vehicle body 1. The collection camera 151 collects image information and transmits the collected image information. According to the collected image information, the growth trend of the tobacco leaves is judged, and then the tobacco leaves with poor growth are harvested later. Among them, the implementation method of wirelessly transmitting the received image information by the collection camera 151 is a mature existing technology. This embodiment does not involve the improvement of this part and will not elaborate on this part.

[0031] To facilitate the collection of information by the camera 151, a driving motor 152 is provided on the unmanned aerial vehicle body 1.
