椰子剥壳机的设计
摘要
椰子(Cocos nucifera L.)是棕榈科椰子属植物，为多年生常绿乔木，广泛分布于世界上近100个地处热带的国家和地区，其中主产国是印尼、菲律宾、印度和斯里兰卡等，我国椰子的主要种植区在海南，种植面积和果实产量均占全国的90％以上。椰子果是椰子树的果实，俗称椰子
国人对于椰子的利用传统上采用剖切的方式只是能摄取汁液，剩余果皮残渣就随处丢弃严重制造污染，因此椰农转型推出剥壳椰子，即先行剥除椰子外壳仅存内果皮（硬壳）再加以冷藏保鲜贩售，果皮残渣再经粉碎后当介质利用，作法上较为环保，目前剥壳方式仍以人工为主。本研究针对椰子基本物性加以探讨分析，进而规划设计剥壳机构。调查显示椰子外观大部分呈三稜形，果实由外果皮、中果皮、内果皮组成，外果皮呈绿色或浅黄色，光滑坚实，富韧性，中果皮属纤维层含软木屑包覆着内果皮。经试验结果显示果皮含水率变化与破坏力之间有密切关系，即外果皮破坏力随着含水率下降有逐渐增大现象，中果皮破坏力与含水率多寡无直接关系，但与纤维条数、厚度有关。
本研究设计三角锥型齿剥壳机构以拉扯方式将椰皮撕裂，椰子剥衣工序由人工操作变为机器操作，不仅可以大大提高生产效率，为后期工序提供充足的原材料，更重要的是能够保证操作人员的人身安全，减少伤残事故的发生。同时由于前期工序采用了自动化，不仅可以节省大批的劳动力，而且解决了椰子生产企业扩大生产规模的瓶颈问题，为企业扩大生产规模，提高经济效益开辟新的途径。

Abstract
Coconut(Cocos nucifera L.) is a coconut palm species, is a perennial evergreen tree,widely distributed in theworld's nearly 100 countries and regions located in the tropics,where the main producing countries are Indonesia, the Philippines, India and Sri Lanka, our main coconut growing areas in Hainan, planted area andyield fruits account for more than 90% of the country. Coconut fruit is the fruit of the coconut tree, commonly known as coconut.
For people using traditional cutway using only capable of taking on the coconut juice, peel residue remaining on everywhere discarded serious polluters, so coconut husking coconuts agricultural transformation launch that first strip of coconut shell remaining endocarp( hard shell) coupledwith cold storage to sell, then peel residue after crushingwhen the media use, the more environmentally friendly practices, there is still labor-based shellerway. In this study, to investigate the analysis of the basic physical properties of coconut, and then peel the planning and design agency. Survey shows that the appearance of most of the three prism coconut, fruit from the exocarp, mesocarp, endocarp composed husk green or paleyellow, smooth and solid, rich toughness, mesocarp endocarp fiber-containing layer is a softwood coveredwith. The test results showed close relationship between the peel and destructive changes in moisture content, that husk destructive moisture content decreased graduallywith increasing phenomenon, mesocarp destructive and not directly related to the amount of moisture, but the number of fibers, thickness. The studywas designed triangular pyramidal teeth pulledway Sheller institutions coconut skin torn clothing coconut peeling process by a human operator into a machine operator, not only can greatly increase productivity, provide adequate raw materials for the latter process is more important to ensure the safety of the operator, reduce the incidence of disability accidents. At the same time due to the early adoption of automated processes, can not only save a lot of labor, but also to solve the coconut production enterprises to expand the scale of production bottlenecks for enterprises to expand production scale, opening up newways to improve economic efficiency.
