Seed crystal system capable of eliminating resonance

The invention discloses a seed crystal system used for lifting and rotating a crystal bar, the seed crystal system comprises a rotating base body, a rotary table, a counteracting part and a driving assembly, the rotary table is movably arranged on the rotating base body, the rotary table is connected with a flexible shaft used for lifting the crystal bar, the flexible shaft is driven by the rotary table to rotate circumferentially, the counteracting part is movably arranged on the rotating base body, and the driving assembly drives the counteracting part to rotate circumferentially. The center of gravity of the counteracting part and the center of gravity of the rotary table are both located on the axial center line of the flexible shaft, the driving assembly is configured to be in transmission connection with the rotary table and the counteracting part, the driving assembly is used for driving the rotary table to rotate in the first circumferential direction and further used for driving the counteracting par
