The invention discloses a medicinal material crushing technology for a traditional Chinese medicine injection. The technology comprises the steps that medicinal materials obtained after drying are transferred to a vibrating screen of a crushing machine, the small-size medicinal materials are moved into the crushing machine through vibration of the vibrating screen to be crushed, a powerful suction pipe is arranged on one side of the vibrating screen, the medicinal materials remaining on the vibrating screen are sucked into a treatment box through the powerful suction pipe for cutting treatment, and then the medicinal materials obtained after cutting are introduced to the vibrating screen again to be screened. According to the medicinal material crushing technology for the traditional Chinese medicine injection, a screening technology is additionally conducted before medicinal material crushing, the medicinal materials are screened with the vibrating screen, and the small-size medicinal materials obtained after screening are put into the crushing machine for crushing treatment, so that the medicinal materials are fully crushed; operation is easy, and the later-period percolation treatment effect can be greatly improved.
