Summary:ABSTRACT In response to the problems of high impurity content in ears and poor stalk crushing efficiency during the harvesting of fresh corn, a double fan high-pressure impurity removal and cleaning device was designed based on the operating conditions and mechanical analysis of harvester. Field trials were conducted using fan speed (1200 rpm, 1300 rpm and 1400 rpm) and harvester operating speed (6 km/h, 8 km/h and 10 km/h) as test conditions, with ear impurity content rate and stalk crushing length qualification rate as indicators. Ear impurity content rate ranged from 0.25% to 0.50% and stalk crushing length qualification rate ranged from 96.1% to 98.6%, with test results meeting operation standard under all test conditions. The designed device was able to meet the operational requirements.
