青贮机籽粒破碎装置的设计与试验OA

At present,most of the domestic research on the grain crushing device of the silage machine stays in the imita-tion design stage,and the specific design parameters lack theoretical research.The three parameters of feeding speed,cutting speed and crushing roller speed difference can cooperate with each other to achieve the expected crushing effect.The crushing effect of the crushing device and the shape of the crushing roller are also closely related,this paper focuses on the study and motion analysis of the crushing roller,and selects reasonable parameters by experimenting with different feeding speeds,shredding speeds,and crushing roller speed differences.Through field experiments,it can be seen that the two crushing wheels of grain crushing have better results under a specific speed difference,and the speed of the fixed crushing roller is 3600r/min,and the speed of the floating crushing roller is 3960r/min.
