A novel biological feed device is disclosed. The device includes a machine base, and a processing table fixedly mounted above the machine base through supporting plates. Four corners of the machine base are provided with mounting blocks in an unfixed manner. Bottoms of the mounting blocks are provided with rolling wheels in a rolling manner. The processing table is provided with a rotating cavityinside. The top end surface, of the processing table, on the rotating cavity is provided with an annular slot communicated with and connected to the rotating cavity. The processing table below the rotating cavity is provided with a mounting cavity. A driver is fixedly mounted in the mounting cavity, and is connected to a first rotating shaft extending upward. The upward extending end at the axialdirection of the first rotating shaft penetrates the rotating cavity and protrudes from the top end of the processing table.
