摘要
为考察反转旋耕灭茬作业机械中刀具排列对作业效果的影响,设计了3种反转旋耕刀具排列为基本试验组,以刀具人字排列正转旋耕灭茬为对照组,进行了田间试验。试验结果显示:正转旋耕正人字排列组试验平均驱动功耗27.65k W,耕深稳定性94.6%,优于反转旋耕的3种方案结果;而从埋茬分布率和耕后地表平整度观察情况来看,反旋3种刀具排列方案均优于正转旋耕方案。其中,刀具人字形排列反转灭茬碎土率为89.1%,埋茬分布率为59.6%,高于其他3组。试验结果表明:反转旋耕灭茬整体作业效果优于正转作业,而刀具人字形排列方案为所有反转灭茬中效果最好的排列方案。
For investigating the influence on tillage effectiveness of reverse rotary cultivator,research background is analyzed and three blades arrangement schemes were proposed.The average energy consumption of forward rotary cultivator with backward V type blades arrangement is 27.65 kW,and the stability of tilling depth is 94.6%,which are better than other schemes.The blades arrangement of reverse rotary have better results of buried stubble distribution and the surface roughness after tillage,and soil breaking rate of V type blades arrangement is 89.1%and buried stubble distribu-tion is 59.6%,which are higher than other blades arrangement schemes.The experimental results show that the perform-ance of three blades arrangement shemes of reverse rotary cultivator is better than forward reverse cultivator scheme,as well as the V type arrangement scheme has best tillage performance in given schemes.
