Large-scale corn header design with adjustable line spacing and lifting cylinder motion simulation

Abstract

Existing large corn harvester headers have inflexible walking, fixed line spacing, and cannot be well applied to the harvesting requirements of different line spacings.Based on the existing header, the header is designed to be foldable and the line spacing is adjustable.The dynamics analysis software ADAMS was used to simulate the hydraulic cylinder of the lifting header.The results show that under uniform load, the connection between the hydraulic cylinder and the vehicle body and the connection between the hydraulic push rod and the conveying bridge are large, and the lifting speed is positively correlated with the force. The offset load has an influence on the force of the motion pair and has the greatest influence on the force between the hydraulic push rod and the transport bridge. When the strength check is performed, attention should be paid to ensure that the strength and life reach the design requirements.
