中文摘要：

设计了一种玉米根茬根土分离装置，该装置主要以双辊碾压脱土机构和双组柔性连接飞锤击打脱土机构的联合作用，对玉米根土复合体施以碾压、揉搓、击打和撞击等多种方式进行脱土作业。试验结果表明，在土壤质地为中壤土，土壤含水率为15％～20％的情况下，该装置平均根土脱净率为98．12％，平均根茬损失率为0．92％，平均生产率为2．43t／h，实现了根茬与土壤的有效分离。

英文摘要：

In order to solve the problem of mechanical harvest of corn stubble, a roots-soil separating device of corn stubble was developed. It consisted of a double roller compacting mechanism and a dual flyweights-hit mechanism with flexible connection. The co-action of two mechanisms on corn roots-soil complex were compaction, rub, hit, impact and other ways to achieve the function of roots-soil separation. When the soil texture was medium loam and the soil moisture was 15% - 20% , the test results showed that the average roots-soil separating rate was 98.12% , the roots-soil separating loss rate was 0.92% and the average efficiency reached 2.43 t/h. The device could realize the effective separation of stubble and soil.
