设计简介
摘要：桔子是我国重要的水果，改革开放和农村产业的调整促进桔子产业的发展，桔子产业的快速发展，也带动了桔子生产作业机具的研究和发展，我国桔子生产机具的开发虽具有一定的基础，但与桔子产业化发展需求还有很大的距离，进口专业开沟机价格昂贵，因此研制出满足农户需求，价格低廉的桔园专业开沟机设备是非常必要的。
桔园开沟机的开沟部件采用螺旋开沟刀具，其特点是，结构简单、部件紧凑、动力消耗少、行走速度快、能很好地适应桔园作业环境，提高劳动效率。

Abstract:Orange is an important fruit, The development of the orange industry have promoted by reforming and opening and the regulation of rural industrial structure. It also drove orange production equipment research and development, Orange production equipment development has certain foundation in China,but it also has long distance from the development need of industrialization and imports professional ditching machine is expensive, therefore ,develop to meet the farmers' demand, manufacture low price and professional citrus orchard ditching machine equipment is very necessary.
Orchard ditching machine ditching components adopting helix ditching cutter, which is characterized by simple structure, compact, less power consumption, high running speed, and can be well adapted to the orchard operating environment, improve labor efficiency.
