摘　　要：针对青饲料收获机在茎穗收获作业时蜡熟期籽粒难破碎,影响青饲料适口性及消化吸收难的问题,设计了用于提高青贮玉米籽粒破碎效率的对辊式籽粒破碎装置,基于Solid Works对盘刀及破碎辊轴进行了静力学特性分析。经初步生产应用,该籽粒破碎装置结构紧凑,工作面长度远远超过了传统的破碎辊,大大降低了能耗,籽粒破碎率达到了90%以上。A new-type grain crushing device was designed to overcome the low crushing rate in maize which decreased the forage palatability as well as digestion and absorption of nutrients. A statics analysis of the disc knife and a crushing roller shaft was carried out based on SolidWorks. Practical application of the device demonstrated that the grain crushing device displayed a compact structure with longer working surface and lower energy consumption. The grain crushing rate might be as high as 90%.
