[0021] As attached Figure 1 , Attachment Figure 2 The utility model medicine drying device is shown, comprising a bottom plate 1, a drying chamber 2 is installed on the bottom plate 1, and a plurality of trays 3 are installed at intervals in the vertical direction in the drying chamber 2. The trays 3 are used to carry medicines. The edges of the trays 3 have connecting rods 4 that connect each tray 3 in sequence, so that the plurality of trays 3 are connected into a whole. The tray 3 comprises a circular bottom plate and a side wall surrounding the bottom plate. A first driving device 5 is installed below the bottom plate 1, and the output end of the first driving device 5 passes through the bottom plate 1 and is connected to the bottommost tray 3 and drives several trays 3 to rotate synchronously. A through hole is processed in the center of the tray 3, and a second driving device 6 is installed on the top of the drying chamber 2. The output end of the second driving device 6 is connected to a connecting shaft 7 that passes through the through hole, and a brush plate 8 corresponding to the tray 3 is installed at intervals along the length direction of the connecting shaft 7. One end of the brush plate 8 is connected to the connecting shaft 7, and the other end extends in the horizontal direction. The length of the brush plate 8 is slightly smaller than the inner diameter of the tray 3, and each brush plate 8 moves up and down above the corresponding tray 3 under the drive of the second driving device 6. A plurality of warm air ducts 9 surrounding the tray 3 are installed in the drying chamber 2 . The warm air ducts 9 are provided with a plurality of nozzles 10 facing the tray 3 to spray warm air into the tray 3 .

[0022] A first ring 11 concentric with the connecting shaft 7 is installed on the base plate 1, and a ring-shaped lower groove is processed on the upper surface of the first ring 11. A second ring 12 corresponding to the first ring 11 is installed on the bottom surface of the lowest tray 3, and an upper groove corresponding to the lower groove is processed on the lower surface of the second ring 12. An annular cavity is formed between the lower groove and the upper groove, and a number of balls are placed in the cavity. When the tray 3 rotates under the drive of the first driving device 5, the balls roll in the cavity, making the rotation of the tray 3 smoother. The first ring 11 and the second ring 12 bear the weight of the tray 3 to make it more stable.

[0023] A linear bearing 13 is installed at the center of the tray 3, and the connecting shaft 7 passes through the linear bearing 13, so that the connecting shaft 7 can slide up and down more stably, and the whisk plate 8 connected thereto can be prevented from shaking.

[0024] The medicine drying device of the utility model also includes an air inlet duct 14 and an air outlet duct 15. The air inlet duct 14 passes through the bottom plate 1 and enters the drying chamber 2 and is connected to each warm air duct 9. The air outlet duct 15 is connected to the drying chamber 2 and extends outward. The air inlet duct 14 is connected to a hot air blower. The end of the air outlet duct 15 is connected to a negative pressure device to ensure stable circulation of hot air in the drying chamber 2.

[0025] When in use, medicine is poured into each tray 3, the first driving device drives the tray 3 to rotate, and the second driving device pushes the connecting shaft 7 to move the whisk plate 8 downward. Under the rotation of the tray 3, the medicine accumulated in the tray 3 contacts the whisk plate 8, is gradually smoothed and evenly spread in the tray 3, and is blown and dried by the surrounding hot air, so that the medicine is evenly dried; after the drying is completed, as shown in the attached Figure 3 As shown, the whisk plate 8 descends to the bottom plate close to the tray 3. At this time, the first driving device drives the tray 3 to rotate less than one circle. The spread medicines are blocked by the whisk plate 8 and piled up in one place, which is convenient for taking out. There is no need to manually collect the medicines again, which is convenient for collecting dry medicines. The operation is simple and easy to use.

[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
