Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1 - Figure 8As shown, this utility model provides a technical solution for a vacuum drying device with heat conduction function, including a support 1, a drying tank 3 on the top of the support 1, a heat conduction sleeve 4 installed on the outside of the drying tank 3, the bottom end of the heat conduction sleeve 4 penetrating through the support 1 and fixedly connected to the support 1, a shell 2 fixedly connected to the outside of the heat conduction sleeve 4, the shell 2 fixedly connected to the top of the support 1, a coil 40 installed on the outside of the heat conduction sleeve 4, an air inlet pipe 7 installed on one side of the drying tank 3, a vacuum pump 8 installed on the other side of the drying tank 3, a discharge port 5 installed at the bottom of the drying tank 3, a sealing plug 6 installed inside the discharge port 5, multiple cross grooves 16 opened inside the drying tank 3, a cross long plate 17 and a threaded rod 24 provided inside the cross groove 16, the cross long plate 17 slidably connected to the drying tank 3, the bottom end of the threaded rod 24 rotatably connected to the drying tank 3, and a connecting block rotatably connected to the top end of the threaded rod 24, the connecting block being disposed inside the cross groove 16 and fixedly connected to the drying tank 3, the outer side of the bottom end of the threaded rod 24 A lifting block 240 is threadedly connected to the outside of a cross-shaped long plate 17. A first bevel gear 25 is fixedly connected to the outside of the top of a threaded rod 24. A second bevel gear 26 is meshed with the outside of the first bevel gear 25. A transmission structure is provided between multiple second bevel gears 26. A cross-shaped fixing frame 19 is fixedly connected between multiple cross-shaped long plates 17. A rotating shaft 18 is rotatably connected at the center of the cross-shaped fixing frame 19. Two stirring racks 23 are provided on the outside of the rotating shaft 18.

[0030] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the cover structure includes a sealing cover 9 and multiple positioning holes 15. The sealing cover 9 is located on the top of the drying tank 3. Multiple positioning posts 12 are fixedly connected to the bottom of the sealing cover 9. The multiple positioning holes 15 are all opened on the top of the drying tank 3. The positioning posts 12 are located inside the positioning holes 15.

A limit plug 13 is installed on the output end of the drive motor and is set at the limit position. Inside the groove, the cover structure also includes an internal gear ring 29, which is rotatably connected to the top of the housing 2. Multiple small gears 30 are meshed on the inner side of the internal gear ring 29. A rotating rod 31 is fixedly connected to the inner side of the small gears 30.

[0031] Specifically, by rotating the throttle, the worm 36 meshes with the worm wheel 35. The worm wheel 35 drives one of the pinions 30 to rotate through one of the rotating rods 31. One of the pinions 30 meshes with the internal gear ring 29. Through the meshing of the internal gear ring 29 with multiple pinions 30, multiple pinions 30 drive multiple rotating rods 31 to rotate synchronously. Therefore, multiple top plates 32 drive multiple ball seats 33 to rotate. Multiple balls 34 move out of multiple arc-shaped grooves 10 and away from multiple arc-shaped inclined blocks 14. Thus, the restriction on the sealing cover 9 is released, and the sealing cover 9 is lifted upward, which can achieve quick disassembly of the sealing cover 9.
