摘要
收获作业是作物生产过程的重要环节,提高收获作业效率已成为农业生产的重要组成部分。为了进一步研究收获机组时间利用率随地块条件的变化规律,采用跟踪试验方法测取定距离条件下不同联合收获机组作业的各类时间消耗项目,进而建立不同地块条件下不同收获机组各类时间项目及时间利用率的数学计算模型。利用Mat Lab2012a编程计算,绘制出不同收获机组时间利用率随地块长度、面积的变化规律图,从而得出不同收获机组机组适用的地块条件,为不同地块条件的收获作业提供选型依据。通过研究机组作业技术指标随地块条件的变化规律,指导农业机器型号选择。
Harvesting operation is an important part of the process of crop production,improving the efficiency of harvesting operation has become an important part of agricultural production. In order to further study the change rule of the time utilization rate of the harvest unit with the plot conditions,the method of tracking test was used to determine the time consumption of different units under different conditions. Using MATAB2012 a programming calculation,drawing out the different harvest time with the plot length,the area of the change of the plot,so that different harvest units of the application of the conditions for different conditions of the harvest to provide the basis for the selection of. By studying the variation of the operating conditions of the units with the conditions of the plots,the model selection of agricultural machinery.
