Aiming at the current domestic mechanized peeling of seed corn using ordinary corn combine harvester operation with large kernel loss, high cost of peeling production line construction, shortage of drying field peeling equipment and other problems, a mobile seed corn husker was designed, using flexible conveyor belt feeding device, full rubber segmented combination peeling rollers, gas-solid coupling type rapid screening device and separable mobile frame design, in order to improve the efficiency of peeling, reduce kernel damage, and facilitate transport and storage. Through theoretical analyses and calculations on the peeling process of seed corn, the main factors affecting the peeling effect and the structural parameters of key components were determined. The Box-Behnken experimental design principle was adopted to conduct a three-factor, three-level experiment by using peeling roller rotational speed, peeling roller inclination angle and peeling roller bias angle as experimental factors, and bract stripping rate, kernel shedding rate and kernel breakage rate as performance indexes, and the verification test was carried out according to the actual working conditions at the end. The results of multi-objective optimization showed that the optimal combination of working parameters was the peeling roller rotational speed of 265.57r/min, the peeling roller inclination angle of 10.06°, and the peeling roller offset angle of 19.76°，at which time the bract stripping rate was 95.33%, kernel shedding rate was 1.471%, and the kernel breakage rate was 0.661%. The results of the validation test showed that at the optimal parameter combination of the bract stripping rate was 94.22%, the kernel shedding rate was 1.511%, and the kernel breakage rate was 0.675%, which was basically consistent with the results of the parameter optimization, meeting the operational requirements for mechanized peeling of seed corn. The research result can be used for the design and improvement of seed corn husker to provide a reference.
