| 摘 要： | 目前我国市场上使用的秸秆还田机,粉碎部分都是以高速旋转的动定刀结合的粉碎方式对秸秆进行粉碎,但是因不同地块的秸秆含水量有所不同,这种单一的粉碎方式对粉碎后的秸秆长短不可控制,较长的秸秆在后续的翻埋、碎混等还田作业环节中无法被土壤覆盖,裸露秸秆多,不易腐烂,严重影响下一轮播种作业。研究设计一种秸秆精细粉碎双排定刀还田机,通过前后配置的双排定刀与秸秆精细粉碎刀辊的配合,提高了对秸秆的适应能力。

| Abstract: | The straw returning machine used in our market at present,The crushing part is to crush the straw by the combination of high-speed rotating moving knife and fixed knife.However, the straw moisture content in different plots is different. This single crushing method can not control the length of the crushed straw, and the longer straw can not be covered by the soil in the subsequent operations of turning up, burying, crushing and mixingBare straw, not easy to rot, seriously affect the next round of sowing operations. This paper studies and designs a kind of Straw fine grinding double-row fixed knife returning machine . The adaptability to straw is improved through the cooperation of double-row fixed knives and straw fine crushing knife rolls. |
