The invention discloses biological medicine grinding equipment. The biological medicine grinding equipment comprises a machine body. A crushing cavity with the top being open is formed in the inner top of the machine body. A feeding funnel is arranged on the end face of the top of the machine body. A main rotary shaft is arranged in the crushing cavity in a left-right penetrating mode. A pluralityof blades are fixedly arranged on the outer surface of the main rotary shaft. The right end of the main rotary shaft is in power connection with a first motor in a matched mode. The first motor is embedded in an inner wall body of the machine body. A cavity opening is formed in the bottom of the crushing cavity. A through pipe is arranged on the lower portion of the cavity body in a communicatingmode. A blocking assembly is arranged between the cavity opening and the through pipe. A pushing cavity is formed in the right side of the through pipe. A rotary disc is arranged in the pushing cavity. The center of the rear
