AI Technical Summary
Existing adjustable-gap camellia fruit harvesters are difficult to make precise adjustments over a wide range. The adjustment process is cumbersome and cannot meet the harvesting needs of different fruit branch thicknesses and fruit sizes, resulting in low harvesting efficiency, high costs, and a high rate of flower bud damage.
A layered camellia fruit harvester with adjustable gaps was designed. It adopts a multi-stage adjustable gap adjustment device controlled by a hydraulic system, combined with gear and rack transmission, to achieve precise adjustment of the harvesting gap. It is equipped with a harvesting execution device, transmission unit, lifting mechanism, angle adjustment mechanism and layered execution unit to ensure the harvester's flexibility, adaptability and high efficiency.
It achieves efficient harvesting of branches with different thicknesses and fruits of different sizes, reduces the damage rate of flower buds, improves harvesting efficiency and cleanliness, is highly adaptable, is suitable for the complex growth environment of camellia trees, and has the ability to operate continuously for long periods of time with low noise.
