In response to the current problems of high intensity,low efficiency,and low mechanization in manual walnut picking,a ground walnut picking machine was developed,in which a gathering device was mainly designed and the structural parameters of the key components of the picking machine were determined.Taking the ground walnut as the picking object,taking the forward speed of the pickup machine,the angle of the gathering device,and the rotational speed of the rotating rubber drum as the influencing factors,and the picking rate as the performance index,a quadratic rotation orthogonal combination experiment was conducted to establish a regression model between each influencing factor and the performance index of the pickup machine,and the influence law of each factor on the performance of the pickup machine was analyzed.Using multi-objective optimization method,the optimal parameter combination was determined:forward speed was 0.48 m/s,gathering device angle was 48.66°,rotating rubber drum speed was 3 060 r/min,and the walnut picking rate of the walnut picking machine was 93.6%.After experimental verification,the experimental results were basically consistent with the optimization results,met the requirements for mechanized collection of ground walnut.
