Immersion type silicon core cutting device

The utility model discloses an immersion type silicon core cutting device which comprises a cutting part and a feeding part connected with the cutting part. The cutting cavity is a sealed cavity and is provided with a unique opening, and the cutting cavity is used for being filled with a water source; the unique opening is used for placing a silicon rod; the cutting part and the feeding part are both installed in the cutting cavity. By designing the cutting cavity and filling the water source into the cutting cavity, silicon rods are cut underwater, and when the silicon rods are immersed in the water source, the silicon rods are influenced by buoyancy, so that the phenomenon that the small silicon rods are collapsed due to gaps after being cut is avoided, and the small silicon rods are further prevented from being fractured due to collapsing; and meanwhile, through the design, during underwater cutting, the cooling requirement during cutting is met, and meanwhile the situation that dust is dissipated everywhe
