The invention discloses a medicine decocting device for traditional Chinese medicine. The device comprises a box body, a medicine placement cylinder, crankshafts, rod journals, a sleeve, a connectionrod, a spiral rod, a spiral sleeve, a first stirring shaft, a press plate, first stirring rods, a second stirring shaft, a second stirring rod and a transmission mechanism. The transmission mechanismcomprises a first inclined gear, a second inclined gear and a third inclined gear. The medicine decocting device is provided with the crankshaft, the spiral rod, the spiral sleeve, the first stirringshaft, the second stirring shaft, the first stirring rod and the second stirring rod, the first stirring rods are driven to move up and down and rotate forward and reversely through cooperation at thesame time, so that the medicine decocting efficiency is improved, and the traditional Chinese medicine is heated more sufficiently and evenly; the transmission mechanism is arranged and drives the medicine placement cylinder to rotate through cooperation, and the rotating direction of the medicine placement cylinder is opposite to the rotating directions of the first stirring shaft and the secondstirring shaft, so that the medicine decocting efficiency is further improved; the press plate is arranged, can sufficiently squeeze effective ingredients in the traditional Chinese medicine in medicine decocting, and meanwhile squeezes out residual medicine liquid in medicine residues and waste is avoided.
