摘要
播种机单体仿形机构是保证播种质量的重要工作部件。为此,论述了目前广泛应用的平行四杆仿形机构的结构特点、工作原理、仿形量和连杆长度的设计方法;对研究设计的电液自控仿形机构的结构特点与工作原理进行介绍;对平行四杆与电液自控仿形机构的仿形能力、仿形精度、仿形的灵敏度与能否实现播深的精量控制等方面进行了对比分析。
The profiling mechanism of panter unit is the important components ensuring sowing quality,introdcing the structural characteristics,work Principle of parallel four-bar now widely used,and design method of profiling volume and parallel four-bar＇s length.Describing the structural characteristics and work Principle of electro-hydraulic automatic control profiling mechanism,Comparatively analyze on profiling ability,profiling precision,profiling sensitivity,whether or not realize precision control of parallel four-bar and electro-hydraulic automatic control profiling mechanism.
