[0040] During the specific use of this embodiment, when it is necessary to dry traditional Chinese medicine materials, first add an appropriate amount of traditional Chinese medicine materials into the moving frame 10, and then start the fishing motor 68 through an external PLC. The output shaft of the fishing motor 68 rotates to drive the rotating column 63 coaxially connected thereto to rotate. The rotating column 63 rotates to drive the screw rod 65 coaxially fixed thereto to rotate. The screw rod 65 rotates to drive the connecting rod 66 threadedly connected thereto to move. The connecting rod 66 moves under the guiding action of the guiding block 67 and the guiding groove on the front side surface of the vertical plate end of the vertical plate 62. The connecting rod 66 moves to drive the cylinder cover 5 fixed thereto to move. The movement of the cylinder cover 5 indirectly drives the movement of the moving frame 10. When the moving frame 10 moves into the drying cylinder 2, the moving frame 10 moves under the guiding action of a plurality of sliding strips 12 and a plurality of sliding grooves on the inner wall of the drying cylinder 2. When the cylinder cover 5 is in close contact with the top surface of the drying cylinder 2, the fishing motor 68 is turned off through an external PLC;

[0041] Immediately, the ventilation pipe of the external vacuum system is tightly sleeved with the vacuum pipe 8 and the valve 9 is opened. Subsequently, several heating rings 13 and the vibration motor 15 are started through the external PLC. After the vibration motor 15 is started, it drives the drying cylinder 2 to vibrate. The drying cylinder 2 vibrates under the support of several support legs 3, several springs 4 and several gaskets 16. The vibration of the drying cylinder 2 drives the moving frame 10 and the Chinese medicinal materials inside the moving frame 10 to vibrate, so as to fully dry the Chinese medicinal materials. During the drying process, the vacuum pump in the external vacuum system is started through the external PLC, and then the water vapor generated inside the drying cylinder 2 can be sucked out;

[0042] After drying for a period of time, the external vacuum pump, several heating rings 13 and the vibration motor 15 are turned off through the external PLC. According to the above description, conversely, the moving frame 10 can be moved to a suitable position above the drying cylinder 2, and then the dried Chinese medicinal materials inside the moving frame 10 can be salvaged.
