[0034] Specific working principle:

[0035] As shown in the figure, when using the drying device, first, the medicinal materials to be dried are evenly laid on the drying plate 2, and then the protective door 102 is opened to insert the drying plate 2 into the through groove 4. The limit plate 201 can support the drying plate 2 to keep it on the layer plate 3, and then the drying component is started to start drying the medicinal materials. In the process of drying the medicinal materials, the motor is started at a fixed time, and the motor drives the threaded rod 28 to rotate through the coupling. The threaded rod 28 drives the movable block 7 threadedly connected thereto to move in the movable groove 6, and the movable block 7 drives the installation block 11 to move. The mounting block 11 drives the rotating shaft 13 and the rotating rod 14 to move, and the rotating rod 14 drives the turning shovel 16 to move left and right in the drying tray 2. At the same time, as the mounting block 11 moves left and right, the guide pin 30 provided at the bottom of the mounting block 11 moves along the guide groove 29. The guide pin 30 drives the mounting block 11 to move forward and backward through the wavy guide groove 29, so that the turning shovel 16 moves forward and backward. In the process of the turning shovel 16 moving left and right and forward and backward, the medicinal materials in the drying tray 2 can be fully turned over, so that the medicinal materials in the drying tray 2 can be evenly dried. Heat is used to improve the drying efficiency and the quality of the dried medicinal materials. After the turning is completed, the mounting block 11 moves to the starting position until the top block 25 contacts the top column 26. After that, the mounting block 11 continues to move to allow the top column 26 to push the top block 25, so that the top block 25 approaches the mounting block 11. In the process of the top column 26 approaching the mounting block 11, the moving rod 18 moves relative to the mounting block 11, so that the rack 19 moves relative to the mounting block 11. In this process, the rack 19 rotates the gear 17 meshing with it, so that the rotating shaft 13 drives the rotating rod 14 rotates until the rotating rod 14 rotates into the storage groove 27. During the rotation of the rotating rod 14 along with the rotating shaft 13, the rotating rod 14 will rotate at the same time due to the engagement of the sector gear 31 and the sector rack 32 arranged on the surface thereof. With the rotation of the rotating rod 14, the connecting rod 15 rotates from the vertical to the horizontal, so that the turning shovel 16 is higher than the drying tray 2, and the turning shovel 16 is moved out of the drying tray 2 until the next time the medicinal materials in the drying tray 2 are turned. At the same time, since the turning shovel 16 is moved out of the drying tray 2, the turning shovel 16 can be prevented from interfering with the removal of the drying tray 2.

[0036] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
