Raw material pretreatment device for silage processing

The invention relates to the field of centrifugal facilities, in particular to a silage processing raw material pretreatment device which comprises a hopper seat, a moving table is slidably arranged above the hopper seat, a barrel shell is rotatably mounted at the upper end of the moving table in a penetrating mode, and a centrifugal screen barrel is coaxially and fixedly mounted in the barrel shell; a gap is reserved between the centrifugal screen drum and the drum shell, a feeding part is installed on one side of the upper end of the hopper seat and communicates with the centrifugal screen drum, a first servo motor is installed on the other side of the upper end of the hopper seat, and a push frame is connected between the output end of the first servo motor and the side face of the movable table. According to the centrifugal screening device, the centrifugal screening effect is improved, normal operation of screening operation is ensured, meanwhile, discharging is facilitated, and use is effectively facili
