Abstract: China′s peanut straw is mostly laid in the field to be air dry after picking and then transported to set the stack，this method has low productivity and inconvenient transportation，and occupies more storage space.Based on 4HB-2A type peanut combine harvester，with peanut stalk bundling device，a bundling machine for peanut straw harvesting and bundling was designed.It could change peanut mechanization harvest development of incomplete state，effectively reduce labor demand，improve collection efficiency and quality of peanut straw，and reduce peanut straw transportation and storage costs，so as to facilitate subsequent collection，transportation，storage and processing operations.Field experiments showed that vine recovery effect was good，and design requirements were achieved.
