Culture medium vibration screening device

The utility model relates to a culture medium vibration sieving device which comprises a stirring box, a vibration sieving device body is arranged above an opening of the stirring box, a stirring device is arranged in the stirring box, a spiral conveyor is arranged on one side of the stirring box, and a spraying device for spraying liquid towards the vibration sieving device body is arranged on one side of the stirring device. The upper-layer screen and the detachable lower-layer screen are arranged above the stirring box, different grids of the upper-layer screen can be replaced according to the particle requirements of materials, meanwhile, the upper-layer screen is matched with the lower-layer screen to complete screening of smaller particle materials, the materials fall into the vibration screening device from the spiral conveyor, and through continuous and rhythmic vibration, the materials can be screened out through the vibration screening device. The scattering and screening efficiency is high, materia
