Abstract
Several kinds of main stalk and stubble processing technologies and corresponding machines used in Liaoning Province are researched in this paper. The key parameters influenced stubble chopping are analyzed on the basis of understanding the principles of “ 2BISJ-2110 precision planter”. In order to solve the shortcoming of disturbing much soil and more power loss of“2BISJ-2110 precision planter” and achieve saving materials, reduce the cost and the water massive disappearing due to the agitation of the soil, entire stubble chopping is changed to seed line stubble chopping. Using the computer VB language to study the parameters of stalks and stubbles according to mathematical model about coulter ends and the path. In order to realize the narrow band and shallow treatment of the stalks and stubbles , taking single ridge width as 100-110mm and using the Solidwork software to design and draw rotary blade , L stubble breaking blade, cutter head ,blade holder , roller and so on . 2 kinds of feasible knife roll disposition plans are presented, which provides a design basis for new type narrow band rotary cultivation stalk and stubble chopper.
