为解决杭白菊机械化采摘技术瓶颈,设计一套回转变距式梳齿式杭白菊自走采摘设备.针对杭白菊力学特性和植株特点,确定回转变距梳齿式采摘设备的结构和工作参数;使用UG 10.0 对采摘设备的整体结构进行三维建模,完整呈现整体架构,并对车体以及采摘梳齿关键作业部件进行强度校核分析,确保设备在复杂作业环境下的结构可靠性;在参数优化方面,通过单因素试验初步确定梳齿间隙范围,利用Design—Expert 8.0.6 软件中Box—Behnken试验设计方法进行三因素三水平组合试验.根据试验结果方差分析,以采摘率最大、杂质率和破碎率最小为参数优化目标,回归模型方差分析的P值均小于 0.01,显著性程度极高,3 类评价指标回归模型误差较小,验证模型的有效性和可靠性;基于Design—Expert 8.0.6 软件优化求解,获得最优参数组合:梳齿间隙为 9 mm、梳齿转速为 60 r/min、自走速度为 0.5 m/s,在此工况下,采摘率、杂质率和破碎率分别为 85.78%、16.77%和 2.05%.设备试验过程运行稳定,为杭白菊机械化采摘和产业升级提供重要依据.
To address the technical challenges in the mechanized harvesting of Hangzhou White Chrysanthemum,a self-propelled rotary variable-pitch comb-type harvesting device was designed.Based on the mechanical properties and plant characteristics of Hangzhou White Chrysanthemum,the structural and operational parameters of the harvesting device were determined.The 3D model of the machine was constructed using UG 10.0,with strength verification analysis conducted on key components including the chassis and harvesting combs to ensure structural reliability in complex operating environments.For parameter optimization,the comb gap range was preliminarily identified through single-factor experiments.A three-factor,three-level combined experiment was then performed using the Box—Behnken experimental design method using Design—Expert 8.0.6 software.Variance analysis of the experimental results,with the objective of maximizing the harvesting rate while minimizing the impurity rate and damage rate,showed the regression model's ANOVA P-value were less than 0.01,confirming the validity and reliability of the regression model.Optimization via Design—Expert 8.0.6 yielded the following optimal parameter combination:comb gap of 9 mm,comb rotational speed of 60 r/min,and forward speed of 0.5 m/s.Under these conditions,the harvesting rate,impurity rate,and damage rate reached 85.78%,16.77%,and 2.05%,respectively.The equipment demonstrated stable operation during testing,providing critical technical support for the mechanized harvesting and industrial upgrading of Hangzhou White Chrysanthemum.
