In order to improve the mechanization level of corn sorting, a kind of mechanical device with high efficiency and batch transportation of maize grain was designed to solve the problem that traditional corn sorting machine of grain was difficult to realize the batch transportation. The main structure, working principle and related structure parameters of the batch transportation device were described. Structural design of key components of the device, analysis of performance characteristics of amplitude difference type electromagnetic vibration system and batch transportation track were introduced. EDEM virtual simulation test was done on the device performance of the batch transportation, track arc central angle, wedge baffle angle and track width were taken as experiment factors, and batch column performance indicators were selected as test index of the virtual orthogonal experiment. The influence of related factors on the performance of the batch transportation was analyzed, and reasonable parameter combination was obtained as: the track width of 15.4mm, track arc central angle of 45° and wedge baffle angle of 110°. The bench test was carried out, the bench test results showed that the electromagnetic vibration amplitude was 1.5mm, frequency was 52Hz, the vibration direction angle was 28°, the installation angle was 0°, the added mass was 0.3kg, one side of plate spring was adjusted to 87°, the other side of plate spring was adjusted to 35°, the amplitude of the track with added mass was 1mm, the batch transportation qualified index was 83.1%, adhesion and retention index was 10.4%, hysteresis index was 6.5%. The batch transportation performance was good, which met the performance requirements of corn seed separator, and the research provided a theoretical and technical reference for the research and design of corn sorting device.
