摘 要
柚子树大多生长于南方，是驰名古今中外的抽子中的优良品种，它不但象征着亲人团圆，还象征生活幸福美满，是深受人们喜爱的吉祥水果。在福建当属漳州平和的柚子最为出名，早在1857年的《闽杂记》中就有所记载，到现在已经有500多年的历史了。本课题正是根据漳州平和的柚子果农所反馈的产品需求，结合柚子果农的实际生产种植活动的现实情况，而进行的新型柚子树的环割工具的设计研究。根据柚子树的生长特点，设计一款便携式手持柚子环割机，可以对柚子树进行自动或者半自动环割，减轻工人劳动量，提高效率。
本课题设计柚子树电动环割机设计，不论是对于改善果农的实际生产工作条件还是为其他种类果树的环割工具的设计研究提供参考价值都具有较好的实际意义。课题基于厦门维斯工业产品设计有限公司的实际项目，以果农的需求作为出发点，协同研发其新产品柚子树电动环割机。

Abstract
Most of the grapefruit trees grow in the south，are well-known at home and abroad in the fine variety of suckers，it not only symbolizes family reunion，but also symbolizes the happiness of life，is a popular auspicious fruit. The grapefruit，which belongs to Zhangzhou peace，is most famous in Fujian Province. It has been recorded as early as 1857 and has a history of more than 500 years. According to the product demand feedback from the pomelo growers in Zhangzhou and the reality of the actual production and planting activities of pomelo farmers，this paper studies the design of a new ring cutting tool for grapefruit trees. According to the growth characteristics of grapefruit tree，a portable design was designed. Hand-held grapefruit ring cutter can cut grapefruit tree automatically or semi-automatically，reduce labor and improve efficiency.
The design of electric ring cutter for grapefruit tree is of great practical significance both for improving the working conditions of fruit growers and for the design and research of other kinds of fruit tree cutting tools. Based on the actual project of Xiamen Weiss Industrial Product Design Co.，Ltd.，and taking the needs of fruit growers as the starting point，the research and development of its new product，grapefruit tree electric ring cutter，is carried out in collaboration.
