    摘要:

    為了實(shí)現(xiàn)根茬的挖掘,、撿拾,、根土分離與放鋪等聯(lián)合收獲作業(yè),，研制了一種偏置式挖掘鏟刀和三輥機(jī)構(gòu),。通過分析偏置式挖掘鏟刀的挖掘特性,，以及三輥機(jī)構(gòu)的運(yùn)動學(xué)特性，確定了工作部件的結(jié)構(gòu)參數(shù)及運(yùn)動參數(shù),。田間試驗(yàn)表明,，偏置式挖掘鏟刀挖掘根茬效果好，三輥機(jī)構(gòu)具有較好的撿拾,、根土分離和放鋪能力,，根茬收獲機(jī)的根茬起挖率、撿拾率和放鋪率均大于90%,，滿足設(shè)計(jì)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.
