The invention discloses a traditional Chinese medicinal material crushing and grinding device for a pharmaceutical machine. The traditional Chinese medicinal material crushing and grinding device comprises a box, wherein three circular crushing disks are fixedly welded on a rotating shaft; crushing cutter teeth are uniformly and annularly arranged on the side walls of the circular crushing disks;a barrier net is arranged at the right end of a heat dissipation pipeline; a heat dissipation fan is arranged inside the heat dissipation pipeline; the upper end of a hydraulic cylinder is fixedly connected with a discharging mesh plate through a piston rod; a grinding groove is formed under the discharging mesh plate; a transmission shaft is uniformly penetrated between front and rear supportingplates; a grinding roller is arranged on the transmission shaft. By adopting the traditional Chinese medicinal material crushing and grinding device for the pharmaceutical machine, the problem of hightemperature caused by friction between the crushing cutter teeth and traditional Chinese medicinal materials is solved; the dust-proof mesh plate can prevent dust and impurities in air from enteringthe box, and the barrier net can prevent the medicinal materials inside the box from splashing into the heat dissipation pipeline during the crushing processv and thus blocking the heat dissipation pipeline.
