Design and Test of a Low-Loss Soybean Header Based on Synchronous Profiling

A synchronous-profiling, low-position-cutting, flexible-reel-belt-conveyor, low-loss soybean header was designed to address the problems of a lack harvesting machines supporting soybean-corn strip intercropping, few existing headers, and high loss rate headers. By establishing dynamic model synchronous-profiling cutting device, key structure operation parameters that affect performance synchronous profiling were determined, while flexible-reel-belt conveyor device determined by theoretical analysis. Based on ADAMS rigid-flexible coupling, simulation analysis conducted working process verifying can effectively control height cutter off ground with undulating accurately quickly respond excitation, meeting requirements low-position cutting. Field tests showed stubble headers are 1.34% 70.36 mm, respectively, which 55% 22.7% lower than reel-type rigid actual production requirements. This study provide reference for structural design reduction losses.
