The invention discloses a vibrating type hanging screen for dewatering ore pulp or performing wet screening to ore pulp. A screening machine comprises a rack, a plurality of strands of screening units, a vibration transmission mechanism, an excitation vibration mechanism, a chute in the bottom of the screening machine and an underpinning groove among the strands, wherein each strand of the screening units, hung on the rack, are communicated hollow cavities, vibration screening cavities are segmentally arranged vertically, a screen is arranged on an inclined surface, each vibration screening cavity is of Z-shaped turning, and the excitation vibration mechanism is used for driving vibration transmission frames of all vibration transmission mechanisms to vibrate up and down, and thus, the vibration screening cavities of all screening units on the same vibration transmission frame at the same height vibrate together, and the vibration is transmitted to the screen surface of the vibration screening cavity. Ore pulp is divided into multiple parallel-connection strands to be spread into pulp surfaces respectively due to the spatial structure design, the ore pulp on the screen can be continued and is connected in series to increase the screen penetrating times and the screening penetrating efficiency is improved by high-frequency vibration.
