Abstract:

Vigorously developing self-propelled combine harvester is important for promoting agricultural mechanization and realizing agricultural modernization in our country. At present, the self-propelled combine harvester is mainly with medium and small size, and the large size one develops very slowly. It is of great significance to study and develop self-propelled combine harvester with over 10 kg/s feed rate for agricultural mechanization. This paper firstly introduced the current situation of abroad self-propelled combine harvester development, and point out that their development trend was developed gradually towards the direction of fully automated harvest with high efficiency, high quality, high intelligence, and high comfortable. Then it introduced the current development status of self-propelled combine harvester at home, and point out that the self-propelled combine harvester was still mainly with medium and small size in China, and the research and develoment of self-propelled combine harvester with large feed rate were still in its starting stage. Through comparison, the paper concluded that there was still big gap between our country and foreign countries. Finally the paper put up some suggestions for combine harvester industries and enterprises, so as to provide necessary references for future development of combine harvester in China.

Key words: combine harvester with large size, large feed rate, mechanized harvesting, harvest with high efficiency
