ABSTRACT

In the harvesting process of corn, the way of direct harvesting can effectively improve the efficiency of harvesting and economic benefits of corn industry. Therefore, in the future corn industry, the way of grain direct harvest is one of the main forms of corn industry harvest in China. However, in the actual corn harvesting process, there are many problems such as high corn grain crushing rate and unclean removal. The main reason is that there is a big gap between the performance and parameters of the corn harvesting machinery used in China and the advanced corn harvesting equipment, which can not meet the current corn harvesting demand in China. Firstly, this paper analyzes the problems existing in the current corn direct harvest mode in China, and finds out that the main reason restricting the promotion of corn direct harvest is the performance problems of the direct harvest equipment; secondly, it analyzes the working principle of the corn direct harvest threshing device and the working forms of several main corn threshing devices, and puts forward the optimal configuration design group of the low damage combined corn threshing and separation device In addition, the optimal experiment of damage rate and degumming rate is carried out, and the combination mode of low damage combined corn threshing and separating device is determined, which can effectively improve the degumming rate of corn direct harvest and threshing work, and effectively reduce the damage rate of corn, etc. the application effect of its popularization and application can effectively improve the recovery efficiency and economic efficiency of corn direct harvest link in China Benefit.
