Abstract

The utility model relates to a three-freedom-degree hybrid vibrating screen which belongs to the field of vibrating and screening equipment. The three space freedom degrees of the vibrating screen can be achieved. The three-freedom-degree hybrid vibrating screen is a three-freedom-degree hybrid connection mechanism consisting of three groups of eccentric wheel rocker mechanisms. The three parallel mechanisms can drive the screen to horizontally move back and forth in the (X) direction, to vibrate up and down in the (Y) direction and to swing left and right in the (Z) direction. Three groups of power mechanisms are independent mechanisms, so the groups of power mechanisms can be either undependable or combined. Motors of the three groups of the power mechanisms are controlled by a frequency converter, so that the vibrating frequency of any group can be changed freely. The materials can jump in the multiple directions by different amplitudes and different frequencies in the vibrating screen, so as to meet the screening demand of different materials. The three-freedom-degree hybrid vibrating screen is convenient to use, has high efficiency, and can be used for vibrating and screening of materials such as medicines, chemicals and crops.
