In addressing the challenges associated with the limited capacity of grain recovery boxes and the absence of an automatic unloading mechanism in contemporary corn harvesters,the structure and transmission pathway of self-propelled corn harvester were redesigned.The existing grain recovery box situated beneath the husking mechanism was reconfigured into a grain receiving box,complemented by the incorporation of an unloading mechanism.Additionally,an independent grain storage compartment was established,culminating in a sophisticated grain recovery system that integrates collection,conveyance,storage,and automated unloading functionalities.Upon installation of this advanced grain recovery apparatus on the harvester,it results in a dual-compartment storage configuration:one large compartment for collecting corn ears and another smaller compartment for capturing corn kernels.These dual compartments are capable of executing independent unloading operations.Field test results indicate that the corn harvester outfitted with this innovative grain recovery device operates reliably.Furthermore,these research findings offer valuable references for the development of corn harvester.
