【摘要】 设计了一款前置灭茬深松、后置旋耕的悬挂式联合整地机。简述了整机结构和工作原理,灭茬、深松、旋耕和镇压起垄部件设计以及动力传递系统方案。整机试验表明,1ZQHF-350/5型联合整地机能够提高拖拉机稳定性;较单独后悬挂式同幅宽整地机,油耗降低6.2%,碎土率提高2.3%,破茬率提高5.8%。更多还原

【Abstract】 In order to reduce the working resistance of soil compaction and the problem of tractor tire caused by crop stubble,a kind of cultivating combined front-stubble-breaking,post-subsoil and rearrotary-tilling was design based on single and combined work of cultivating machines,and the field test was carried out.The experimental results showed that 1ZQHF-350 /5 front-stubble-breaking,post-subsoil and rear-rotary-tilling combined cultivating could enhance the stability of the tractor.The energy saving was about 6.2% and the ratios of pulverizing soil and stubble-breaking were improved above 2.3% and5.8%,respectively.The problems and measures were analyzed in the process of application and promotion,which provided reference for study of large agricultural implements.更多还原
