[0029] A collection basket 18 for collecting scattered quartz sand is provided below the shell 2. The width of the collection basket 18 is smaller than the distance between the drive box 4 and the limit box 8. The collection basket 18 can prevent the quartz sand from spilling onto the ground when the inclination angle of the shell 2 and the melting furnace 1 is adjusted.

[0030] The outer wall of the drive box 4 is fixedly connected to a control panel 19 by screws. The control panel 19 is provided with control buttons for controlling the operation of the first motor 3, the second motor 6 and the melting furnace 1.

[0038] S3. After 30-40 minutes of melting, the arc is turned off, and the mold is pushed out of the melting furnace 1. After demolding, a crucible is obtained. In S3, the first motor 3 needs to be started through the control panel 19 to drive the melting furnace 1 to rotate at a constant speed.

[0039] S4. The crucible is subjected to preliminary dimensional inspection, sandblasting, cutting, secondary dimensional inspection, cleaning and barium coating to obtain the final product.

[0040] In the above steps S1-S3, the user can adjust the tilt angle of the melting furnace 1 through the control panel 19 according to actual conditions, for example, the melting furnace 1 can be tilted toward the side of the worker during loading.

[0041] Working principle: The present invention melts the solar crucible through a melting furnace 1, a mold and other structures. During this process, the melting furnace 1 is rotated by the first motor 3, and the inclination angle of the shell 2 and the melting furnace 1 is adjusted by the second motor 6 and the transmission gear system.
