Abstract：To adress the technical chalenges in themechanized harvesting of HangzhouWhite Chrysanthemum，a self-propeledrotaryvariable-pitchcomb-typeharvesting device was designed.Basedonthe mechanicalpropertiesand plantcharacteristicsof Hangzhou White Chrysanthemum，the structural andoperationalparametersof the harvestingdevice weredetermined.The3Dmodel of the machine was constructedusing UG1O.O，with strength verification analysis conductedon keycomponentsincluding thechassisand harvestingcombs toensure structuralreliabilityin complex operatingenvironments.For parameter optimization，the comb gaprangewas preliminarilyidentifiedthrough single-factor experiments.Athree-factor，three-levelcombined experiment was then performed using the Box—Behnkenexperimental design methodusing Design—Expert 8.O.6 software. Variance analysis of the experimental results，with theobjective of maximizing the harvesting rate while minimizing the impurityrateand damagerate，showed theregression model's ANOVA P value were less than O.Ol，confirming thevalidity and reliability of theregresion model.Optimization via Design—Expert 8.O.6 yielded the following optimal parameter combination：comb gap of 9mm ，comb rotational speed of 60r/min ，and forward speed of 0.5m/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， providingcriticaltechnical supportforthemechanizedharvestingandindustrial upgrading of HangzhouWhite Chrysanthemum.
