摘　　要：目的针对杭白菊采摘过程复杂、采摘效率较低等问题,设计一种与杭白菊植株相容性较好的机械装置结构设计。方法基于试验法设计一种新型杭白菊采摘机结构,利用PRO/E建模分析结构,该结构整体采用高地隙设计,以减少对植株的损伤,便于杭白菊的二次采摘。结果因杭白菊花朵距离地面的标准差为92 mm,则在设计时,梳齿长度可为100 mm,梳齿轴选用直径为62 mm的40Cr,梳齿材料可选用45钢,调质处理,调节范围为距地50~80 cm。整体外观是采用仿生设计。在此基础上,引入有限元方法分析其结构的强度,验证了结构的安全性。结论杭白菊采摘机装置结构设计有效提高了杭白菊的采摘效率,减少了破损率,改善了杭白菊采摘人员的工作环境。The work aims to design a machine that has good compatibility with chrysanthemum morifolium to solve the problems of complicated picking process and high efficiency required in picking chrysanthemum morifolium.Based on the test method,a new type of chrysanthemum morifolium picking structure was designed.PRO/E was used to model and analyze the structure.The structure was designed with a high ground clearance to reduce the damage to the plant and facilitate the second picking of chrysanthemum morifolium.Because the standard deviation of flowers of chrysanthemum morifolium from the ground was 92 mm,when designing,the length of the comb teeth can be 100 mm,and the tooth axis of the comb teeth was 40Cr with a diameter of 62 mm,and the material of the comb teeth can be 45 steel,which was tempered,and the adjustment range was 50-80 cm from the ground.The overall appearance was a bionic design,taken from the semantic meaning of bees collecting honey.On this basis,the finite element method was introduced to analyze the strength of the structure,and the safety of the structure was verified.The structure design of the chrysanthemum morifolium picking device can effectively improve the efficiency of the chrysanthemum morifolium picking,reduce the breakage rate,and improve the working environment for workers.
