Design and Text of Type 2 BMMD-4 No-till Precision Planter for Cotton
摘要
Abstract
The paper according to the characteristic of Huang-Huai-hai wheat area , deep soil , large amounts and strong toughness of root stalk , and the requirements of no-tillage plant , a 2 BMMD-4 type cotton no-tillage precision planter was designed .The planter could finish stubble cutting , ditching and fertilizing , seeding , covering and compac-ting,etc.in one pass.It was equiped with unique cleaning and anti blocking function and sowing depth adjustment and profile function .A model analysis of seedling with shallow rotary device of 2 BMMD-4 type no-tillage planter was built by Solidworks and ANSYS softwares .And the model analysis results showed that For the machine , the corresponding fre-quency of cutter shaft with design speed is far less than the natural frequency so that resonance would be less likely .The results of field experiments showed that the properties of the planter fulfil the design requirements basically .关键词
