收获是农业生产机械化工艺过程中的重要组织成部分。其作业特点是:季节性强、适宜收获期短,工艺组织复杂,作业成本高,机器一次性投资大。因此,收获机械化系统功能的好坏,直接影响生产单位或经营者的经济效益。所以,国内外对收获机械化发展都十分重视,除了在机器设计制造、使用、工艺改进方面作了大量的研究外,从系统角 Harvest is an important part of agricultural mechanization process. Its operations are characterized by: strong seasonal, suitable harvest period is short, complicated process organization, high operating costs, a large one-time investment in machinery. Therefore, the function of the harvested mechanized system has a direct impact on the economic benefits of the production units or operators. Therefore, both at home and abroad attach great importance to the development of mechanization of harvesting. In addition to a great deal of research on machine design, manufacture, use and process improvement,
