The invention provides a complete machine transmission scheme for a rice-wheat combine harvesting and bundling machine. The complete machine transmission scheme mainly comprises a header system, a walking system, a granary system, a lift conveyor system, a bundler system, a threshing system, a cleaning system, a power system, a conveyor trough system, a universal joint II and intermediate shaft assemblies. Power is transmitted in the order that power is transmitted to the walking system, the bundler system, the threshing system and the cleaning system from the power system, the threshing system transmits the power to the granary system and the conveyor trough system, the conveyor trough system transmits the power to the header system, and the cleaning system transmits the power to the lift conveyor system (IX). According to the complete machine transmission scheme, the arrangement problem of a transmission line for grafting a bundler to a combine harvester is solved, the complete machine structure layout is reasonable in structure, all the functional parts coordinately work, and the purpose of integrating multiple operation of combine harvesting and straw bundling is achieved.
