Scope

Main technical content: It specifies the terms and definitions of vibratory lychee harvesters, product models, requirements, test methods, inspection rules, marking, packaging, transportation, and storage. **Side-shift distance**: The harvester has a lateral translation function. To prevent the harvester from overturning, the maximum lateral movement distance of the brush vibration device should not exceed 0.5 m. **Harvesting height**: When the harvester operates in an orchard environment, the lifting height of the brush vibration device should not be less than 3.5 m. **Profiling angle**: When the harvester operates in an orchard environment, the inclination angle of the brush vibration device should not exceed 30°. **Vibration frequency**: When the fruit detaches from the stem during normal operation of the harvester, the working frequency range of the brush rod group of the brush vibration device should be 10–30 Hz. **Vibration amplitude**: When the harvester operates in an orchard environment, the reciprocating swing angle of the brush rod group of the brush vibration device should be 0°–75°. **Braking performance**: Under rated speed and load conditions, the braking distance of the harvester should not exceed 0.5 m. **Climbing ability**: During normal operation in an orchard, the climbing angle of the harvester should not be less than 20°. **Harvesting efficiency**: The ratio of the total mass of fruit harvested from a single lychee tree to the time spent harvesting should not be less than 30 kg/h. **Purity rate**: After completing the harvesting operation of a single lychee tree, the ratio of the total number of harvested fruits to the total number of harvestable fruits on the original tree should not be less than 80%. **Damage rate**: After completing the harvesting operation, the ratio of damaged fruits to the total number of harvested fruits should not exceed 10%.
