The sample shaking device comprises a barrel, a motor is fixedly connected to the bottom of an inner cavity of the barrel, a rotating shaft is fixedly connected to the power output end of the top of the motor, a rotating disc is fixedly connected to the top end of the rotating shaft, a rotating barrel is arranged above the rotating disc, and a test tube is arranged in the inner cavity of the rotating barrel. The rotating disc is driven by the motor to rotate, so that the rotating drum is driven to rotate, a sample in an inner cavity of the test tube is shaken, and meanwhile, the rotating drum transversely moves during rotation through the convex blocks on the inner wall of the drum body and the second spring, so that the shaking amplitude is increased, and the shaking effect of the sample is improved.
