Aiming at the problem of poor operation effect caused by seed leakage due to the highspeed operation of the existing corn high speed air suction seed metering device, a double disturbance auxiliary filling high speed air suction seed metering device was designed by increasing the seed filling area, increasing the seed filling time of the seed metering disk, strengthening the dispersion of the population and reducing the adsorption pressure. The stress balance equation of seed layer with different heights was analyzed, and the position and structural parameters of expansion plate were calculated. The mechanical model of seed movement under the action of disturbing seed column and shaped hole was analyzed, and the key structural parameters of seed metering disc with middle shaped seed suction hole with disturbing seed column were determined. Taking the transient normal stress of particles as the evaluation index, the disturbance performance of the three seed trays was simulated by EDEM software, and the seed filling performance of the three seed trays was tested by bench test. The results showed that the designed seed trays can effectively strengthen the dispersion of the population and strengthen the seed absorption performance of the seed trays. The bench test results showed that when the operating speed of the high speed air suction maize seed metering device with disturbance assisted seed filling was 8~10km/h and the adsorption negative pressure was 3.0~4.0kPa, the leakage absorption rate was less than 5.1% and the gravity absorption rate was less than 4.2%, the qualified index of grain distance was greater than 94.6%, and the coefficient of variation of qualified grain distance was less than 15.33%. When the operating speed was 12~14km/h and the adsorption negative pressure was 3.5~4.0kPa, the leakage and absorption rate was not higher than 7.9% and the gravity rate was not higher than 1.3%, the qualified index of grain distance was greater than 92.1%, and the coefficient of variation of qualified grain distance was less than 17.67%. The operating performance was better at high speed, and all the indexes were better than that of the national standard.
