振动式果品收获技术机理分析及研究进展

Mechanism of vibratory fruit harvest and review of current advance

近年来随着劳动力成本的日益提高,许多发达国家的研究人员对果品机械化收获技术进行了广泛而深入的研究,在探索果品收获的新方法、开发果树收获机械方面取得了丰硕的成果。该文首先分析了"果树-机械"收获系统的动力学模型,简要介绍了连续式收获机的设计要素及步骤。随后介绍了振动式果品收获技术的最新研究进展,对现有的4种振动式收获技术做了较为深入的分析,并对振动式果品收获技术的后续研究方向做了简述。

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.
