Combine harvester isa machine using harvester and thresher with a transportation . bine harvester can finishes harvesting, threshing, cleaning and bagging all at once. Itnot only improves work efficiency, reduces the costs, but also solves the manpower and material resource s, reduces the burden of farmers. All those urge us want to make r ice e true. The topic of thesis is about the walking system bine harvester, how to discuss, research and design it is the key of this thesis. This thesis illustrates the significance of the researching th is topic, introduces the development, current situation , future direction and the tendency in domestic and overseas bine-harvester .T hen design the g eneral layout plan and argue its traveling mechanism .W hen the project is approved, we should c alculate and check the mainly parts, including the choose and install of the diesel, f rame, connecting rod ,t rack, driving wheel, roller and the design and calculation of tensioning device .F inally, c ollect, analy ze and check the design parameter to figure out whether they are fit with the production requirement s, and then conclude the characters and disadvantages of this thesis.
