The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1:

[0024] Please see Figures 1-4 As shown, this utility model provides a drying device for camphor leaves, including a drying chamber 1 and a drive motor 17. A holding frame 3 is placed at the lower end of the inner cavity of the drying chamber 1, and a guide hole 21 is opened at the bottom of the holding frame 3. An air guide tube 25 is fixedly connected to the middle of the bottom of the drying chamber 1, and a PTC heater 20 is fixedly installed at the top of the air guide tube 25. A fan blade 23 is movably connected to the middle of the bottom of the air guide tube 25 through a bearing. A fourth pulley 22 is fixedly installed at the bottom of the fan blade 23. Both ends of the top of the drying chamber 1 are movable through bearings. A rotating sleeve 19 is connected, and a stirring rod 11 is slidably connected to the inner cavity of the rotating sleeve 19. A second pulley 12 is fixedly installed on the upper end of the outer surface of the rotating sleeve 19. A rotating shaft 14 is fixedly installed at the output end of the drive motor 17. A first pulley 7 is fixedly installed on the top of the rotating shaft 14. A first belt 8 is connected between the surface of the first pulley 7 and the surface of the second pulley 12. A third pulley 15 is fixedly installed on the lower end of the rotating shaft 14. A second belt 18 is connected between the middle end of the third pulley 15 and the middle end of the fourth pulley 22.

[0025] In this technical solution, the camphor leaves to be dried are placed inside the drying chamber 1 by the setting of the holding frame 3. Through the setting of the drive motor 17, the rotating shaft 14, the third pulley 15, the second belt 18, the fourth pulley 22, the fan blade 23, the PTC heater 20 and the guide hole 21, the camphor leaves placed inside the holding frame 3 are dried with hot air. At the same time, under the action of the rotating shaft 14, the first pulley 7, the second pulley 12, the rotating sleeve 19 and the stirring rod 11, the camphor leaves piled up inside the holding frame 3 can be stirred and turned while the hot air is drying. This makes the piled camphor leaves evenly heated and dried during the hot air flow, thereby effectively improving the uniformity of the camphor leaf drying operation, ensuring the quality of the camphor leaves in subsequent processing, and facilitating personnel use.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, an electric push rod 9 is fixedly installed at the middle of the top of the outer surface of the drying oven 1. A horizontal plate 10 is movably connected between the tops of the two stirring rods 11 via bearings. The output end of the electric push rod 9 is fixedly installed at the middle of the bottom of the horizontal plate 10.

[0028] In this technical solution, by setting up the electric push rod 9 and the horizontal plate 10, after the camphor leaves inside the container 3 have dried, the personnel can use the external controller to control the electric push rod 9 to extend and push the horizontal plate 10 to move upward. The movement of the horizontal plate 10 can drive the stirring rod 11 to move upward, so that the stirring rod 11 can be disengaged from the inside of the container 3, thereby making it convenient for personnel to take out the container 3 and the camphor leaves from the inside of the drying box 1.

[0029] Example 3:

[0030] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the surface of the stirring rod 11 is provided with a guide groove 27, the inner cavity of the rotating sleeve 19 is fixedly connected with a guide block 26, the surface of the guide block 26 is slidably connected to the surface of the guide groove 27, the middle end of the front surface of the drying box 1 is threaded with a locking bolt 5, there are two locking bolts 5, the surface of the locking bolt 5 is in contact with the upper end of the front surface of the container frame 3 with a baffle 4, the upper end of the drying box 1 is fixedly connected with a support plate 13, the upper end of the rotating shaft 14 is movably connected to the surface of the support plate 13 through a bearing, the bottom of the outer surface of the drying box 1 is fixedly connected with a mounting bracket 16, the top of the drive motor 17 is fixedly installed on the bottom of the mounting bracket 16, the bottom of the air duct 25 is fixedly installed with dust filters 24 around the bottom, the bottom of the outer surface of the drying box 1 is fixedly connected with support columns 2 around the bottom, the bottom of the four support columns 2 is fixedly connected with a load-bearing base plate, and the right end of the top of the outer surface of the drying box 1 is fixedly connected with an exhaust pipe 6.

[0031] In this technical solution, the guide groove 27 and guide block 26 are used to guide the rotating sleeve 19 and the stirring rod 11, ensuring that the rotating sleeve 19 and the stirring rod 11 can rotate synchronously. The locking bolt 5 and baffle 4 are used to limit the position between the container frame 3 and the drying box 1, preventing the container frame 3 from falling out of the drying box 1. The support plate 13 and mounting bracket 16 are used to support the upper end of the rotating shaft 14 and to install the drive motor 17. The dust filter 24 is used to filter the dust in the air flowing through the air duct 25, improving the cleanliness of the transported air and preventing contamination of the camphor leaves. The support column 2 and the load-bearing base plate are used to support the bottom of the drying box 1.

[0032] The working principle of this utility model is as follows: The holding frame 3 allows for the placement of camphor leaves to be dried inside the drying chamber 1. When drying is required, an external controller activates the PTC heater 20 and the drive motor 17. The drive motor 17 rotates the shaft 14, the first pulley 7, and the third pulley 15. The rotation of the third pulley 15, via the second belt 18, drives the fourth pulley 22 and the fan blades 23. Simultaneously, the rotating fan blades 23 draw in outside air, which is then blown into the drying chamber 1 through the air duct 25. This air is then effectively heated by the PTC heater 20. This allows hot air to flow through the guide hole 21 into the camphor leaves placed inside the container frame 3, thus enabling the hot air to dry the camphor leaves under the action of airflow. At the same time, the rotation of the first pulley 7 drives the second pulley 12 and the rotating sleeve 19 to rotate through the first belt 8. The rotation of the rotating sleeve 19 drives the stirring rod 11 to rotate, which in turn stirs and turns the camphor leaves accumulated inside the container frame 3. This ensures that the accumulated camphor leaves are heated and dried evenly during the hot air flow, effectively improving the uniformity of the camphor leaf drying process, ensuring the quality of subsequent processing of the camphor leaves, and facilitating personnel use.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
