摘　　要：我国北方玉米茎秆存在粗大、行距宽、深松阻力大等因素,造成深松作业功耗较大、深松铲磨损严重等问题。为此,设计了一种北方玉米地仿生振动式深松机,介绍了整机振动装置的原理和主要部件结构参数的确定。基于仿生减阻原理,对深松铲齿和铲柄进行了仿生设计,在此基础上,对深松铲齿进行了有限元仿真校核。样机在振动和挤压两种工作模式下的性能对比试验表明:振动模式下,牵引阻力减少了10%~17%。研究成果对加快促进保护性耕作技术在中国北方农业区的推广与普及具有重要的意义。Because of our country northern corn stem thick,row spacing wide,the soil resistance heavily,considering the problems,this study designs a bionic vibrant subsoiler for corn fields,determines the mechanism of the machine and the structure parameters of the main components.On this basis conducts FEM on the shovel tooth in SolidWorks based on the vibration device movement and stress analysis.When the prototype is completed,we carried out traction resistance comparison on it.The test run of the prototype shows a reduction of 17%-26%in the traction resistance is acquired in the vibration subsoiling mode than the extrusion subsoiling mode when the speed of tractor is 1m/s and the speed of output axle of the tractor is 540r/min.The invention of this machine has important significance for promoting the extension of conservation tillage technology and popularization.
