摘要
大豆收获是大豆生产过程中一个关键环节,采用适当的收获机械适时完成大豆收获作业是大豆丰产丰收的重要保障。大豆机收损失一直是大豆机械化收获存在的一个严重问题,国内外针对损失问题进行了多年的研究,损失率也在不断的降低,但仍不能满足需求。为此,从减少大豆机收损失出发,对大豆割台、输送装置、脱粒清选装置等关键部件的研究现状以及大豆收获方式、机理研究方法等方面的研究现状进行了梳理和总结,并在此基础上,提出了大豆收获机械今后的研究重点。
Soybean harvest operation is a key link of soybean production process , using appropriate harvesting machinery timely complete the soybean harvest is an important guarantee of soybean ’ s rich harvest .Soybean yield loss has been a serious problems of the soybean harvest mechanization ,it has many years of research history at home and abroad , and it has been reduced , but still cannot meet the need .To further reduce the loss , we summarize the research status of soybean cutting machine ,conveyor , threshing and cleaning device , key components and the soybean harvest method , mechanism research methods .we will put forward the research emphasis of soybean harvest machinery on the basis of existing research results .
