Weighing structure of crystal growing furnace

The utility model relates to the field of crystal growth, in particular to a weighing structure of a crystal growth furnace, which comprises a weighing mechanism, the weighing mechanism is arranged at the top of the outer part of a furnace body, the weighing mechanism comprises a weighing piece, the weighing piece acts on a crystal ingot and is used for weighing the crystal ingot; the feeding mechanism is arranged on the side edge of the outer portion of the furnace body and used for adding raw materials into the furnace body. The weight of the crystal ingot is detected through the weighing mechanism, the increment of the crystal ingot within a certain time is the decrement of the melt, the opening and closing plate is driven by the first motor and the lead screw, so that the material opening of the hopper is opened, and raw materials enter the crucible from the hopper to be fed; quantitative feeding is achieved by controlling the opening degree and the opening time of the opening and closing plate, so that t
