Screening device for probiotic feed processing

The utility model discloses a screening device for probiotic feed processing in the technical field of screening devices, which comprises a bottom plate, two support frames are fixedly mounted at the upper end of the bottom plate, the upper ends of the two support frames are rotatably connected with a conical roller, the roller is obliquely arranged, and a plurality of arc-shaped screening plates are embedded in the roller. The rotary drum is supported in an inclined rolling mode through the two supporting frames, the servo motor at one end drives the rotary drum to rotate, the screen plates are connected to the rotary drum in an embedded mode, the screening area is enlarged, and the screening efficiency is improved; materials are rapidly screened in cooperation with gravity in the rolling process of the inclined roller, kinetic energy input is effectively reduced, the screened materials are received through the receiving plate and guided out through the material guiding opening, the materials are guided out
