The invention discloses a stirring machine of chemical pressing-filtration residue mixture for a laboratory, belonging to the field of industrial machine. The stirring machine comprises the following three mechanisms: a lifting mechanism, a stirring mechanism and a vibrating mechanism, wherein the lifting mechanism realizes a lifting function by a screw lifting machine controlled by a motor. The stirring mechanism transfers power to a main shaft in a transmission box by a coupling through a double-speed motor and reduces the speed of the main shaft, the main shaft drives a stirring blade fixed on an eccentric seat to carry out revolution, and simultaneously the stirring blade rotates automatically around a fixed inner gear by a planetary gear at the upper end of a stirring blade shaft. A motor with double output shafts at the two ends is arranged at the lower part of a platform surface of a vibrating platform of the vibrating mechanism, and the double output shafts at the two ends are respectively provided with two groups of vibrating wheels with vibrators to generate exciting force so as to realize a vibrating function. The stirring machine provided by the invention has the advantages that the chemical pressing-filtration residue mixture is more uniform and efficient.
