旋耕刀排列方式对反转旋耕机作业性能的影响研究

Study on the Effect of Rotary Tillage Knife Arrangement Style on Operation Performance of Reverse Rotary Tiller

以秸秆还田作业为背景,研究反转旋耕机刀辊排列方式对作业性能的影响。为此,设计了4种刀辊排列方式,分别为螺旋排列、人字排列、双人字排列及正人字排列,从旋耕作业主要性能指标及秸秆还田指标去分析。结果表明:①功耗方面刀辊排列方式影响比较明显,在耕深稳定性、碎土率、植被覆盖率方面,刀辊排列方式影响并不明显;②在秸秆分布方面,4种排列方式对于机具作业影响基本相同,都未到达秸秆深埋的效果。

This paper has reserched the effect of the arrangement mode of totary blade to the operation performance of reverse rotary tiller basiced on straw turnover. This paper has designed four kinds of arrangement stye for knife roller,such as spiral,people word,double people word and upright people word and studied on the rotary tillage performance index as well as the straw returned index. The results show that:(1)the influence of the rotary blade arrangement style of machine on the power consumption is obvious,and it is not obvious on depth stability,soil breaking rate and vegetation coverage.(2)in the field of straw distribution,the influence of the four ways of arrangement on operation performance is similarity and have not finished the deep burial work.
