This equipment is mainly used for grading and discharging medicinal materials. Through the vibration effect, the medicinal materials produce high-frequency vibrations on the screen, thereby realizing the separation and screening of medicinal materials of different particle sizes. With the continuous development of the pharmaceutical industry and the optimization of the drug preparation process, higher requirements are put forward on the screening accuracy and efficiency of medicinal materials. The vibrating screen for grading and discharging medicinal materials, as a device specially used for medicinal material screening, can effectively improve the screening accuracy and efficiency and meet the needs of the pharmaceutical industry for medicinal material processing.

[0003] The prior art also has the following defects during use:

[0004] 1. The vibrating screen machine in the prior art cannot well realize the transportation of graded medicinal materials during the process of grading medicinal materials. When the medicinal materials are transported out through the screening rack, the height problem of the bevel may cause the speed of medicinal materials transportation to continue to increase. If the lower material plate is not protected, the medicinal materials will be scattered on both sides of the lower material plate and fall to the ground.

[0005] 2. In the process of collecting medicinal materials by the vibrating screen machine in the prior art, because the medicinal materials will fall downward into the collection box through the discharge plate, the fall from a certain height may cause the medicinal materials to collide when entering the collection box, thereby damaging the medicinal materials, which is not conducive to the collection of medicinal materials and will cause great losses.
