Mechanism of vibratory fruit harvest and review of current advance

In recent years, fruit tree mechanical harvest technologies were widely and intensively investigated in developed countries due to continuously rising labor cost. Some significant accomplishments have been published regarding new methods of fruit harvest and development of harvest machine. The dynamic model of ‘tree-machine ’ harvest system was analyzed in this paper at first, and the essential elements and design procedure of continuous harvest machine were also briefly summarized. The latest research status of vibratory fruit harvest was introduced and existing technologies were then classified into four different kinds of groups which were then analyzed accordingly. Finally, the prospects of vibratory harvesting technology were discussed.
