[0022] It should be noted that, in this embodiment, the crucible 10 is heated by a heating furnace 8. A support frame 9 is provided in the heating furnace 8, and a plurality of mounting positions 91 for mounting the crucible 10 are provided on the support frame 9.

[0023] According to the crucible transportation device of the present utility model, when it is necessary to take out the crucible 10 from the heating furnace 8, first, place the tray under the crucible 10; then, adjust the lifting mechanism 3 and make the lifting mechanism 3 drive the tray 4 to move upward together until the tray 4 lifts the crucible 10 and the support frame 9 together; finally, under the action of the moving seat 1, the crucible 10 can be transported to the corresponding place. Compared with the prior art method of using crucible tongs to clamp the crucible for transportation, it can avoid the breakage and dropping of the crucible wall, improve the safety performance during the transportation process, and greatly reduce the occurrence of safety accidents; in addition, one lift of the tray 4 can realize the transportation of multiple crucibles 10, which can save time and improve work efficiency.

[0024] Exemplarily, the lifting mechanism 3 includes a lead screw 31, a lifting plate 32, a connecting rod 33 and a guiding assembly 34. The lead screw 31 is vertically arranged and rotatably connected to the fixed plate 2. The lead screw 31 is in threaded connection with the lifting plate 32. The lifting plate 32 is fixedly connected to the support plate 4 through the connecting rod 33. The guiding assembly 34 is fixedly connected to the fixed plate 2, and the lifting plate 32 is slidably connected to the guiding assembly 34 in the up and down direction.
