| 摘 要： | 为了实现根茬的挖掘、捡拾、根土分离与放铺等联合收获作业，研制了一种偏置式挖掘铲刀和三辊机构。通过分析偏置式挖掘铲刀的挖掘特性，以及三辊机构的运动学特性，确定了工作部件的结构参数及运动参数。田间试验表明，偏置式挖掘铲刀挖掘根茬效果好，三辊机构具有较好的捡拾、根土分离和放铺能力，根茬收获机的根茬起挖率、捡拾率和放铺率均大于90%，满足设计和使用要求。

| Abstract: | Offset digging shovel and three-roller mechanism were developed to realize the complete working process of root stubble harvest, which included root stubble digging, picking up, stubble-soil separating and root stubble paving. Structural and kinematic parameters of a root stubble harvesting machine were determined by analyzing digging characteristics of the shovel and kinematics of the three-roller mechanism. In field tests, the offset digging shovel demonstrated competency of digging, and the three-roller mechanism showed capability of picking up, separating and paving. The stubble digging, picking up and paving rate of stubble harvest machine were more than 90%. Its work met the requirements of design and application. |
