Description

Technical Field

[0001] The utility model relates to a tobacco leaf harvesting device which is convenient for turning and moving, and belongs to the field of tobacco harvesting tools. Background Art

[0002] Tobacco leaf pickers are tools or equipment specifically used to pluck tobacco leaves from tobacco plants, playing a vital role in the tobacco production process. With the advancement of agricultural technology, tobacco leaf pickers are gradually evolving from traditional manual tools to mechanized and intelligent equipment, aiming to improve picking efficiency, reduce labor intensity, and lower labor costs.

[0003] Existing tobacco leaf picking devices, such as the patent name "A Human-Machine Collaborative Tobacco Leaf Harvesting Vehicle" and the patent number "202322030366.0", have the following technical means: "including a chassis, a tobacco leaf conveying mechanism and a leaf storage mechanism detachably connected to the chassis, and also including a power unit, a control unit and a manual harvesting unit arranged on the chassis; the chassis includes two crawlers arranged parallel to each other, and a chassis frame fixedly connected to the two crawlers by a connecting rod; the power unit includes a plurality of generators symmetrically arranged on the chassis frame, and the side of the chassis frame is provided with a remote control, a display screen and a microphone respectively connected to the control unit for communication; the The manual harvesting unit includes footrests symmetrically fixed to the bottom of the chassis frame and seats detachably connected to the bottom of the chassis frame. This utility model utilizes a control unit and manual harvesting unit to achieve human-machine collaboration, allowing for the vehicle's speed and direction to be adjusted at any time, improving tobacco harvesting efficiency and reducing the labor intensity of harvesters. While it can significantly reduce the labor burden on tobacco farmers by carrying them, its overall length requires ample turning space at both ends of the tobacco field to allow the device to maneuver and enter the tobacco ridges for harvesting. This makes it unsuitable for complex mountainous terrain, such as terraced fields.
