The Oscillation Amplitude of each section of the present invention compass screen surface can be regulated by the eccentric block of configuration different quality, the vibration frequency of each section compass screen surface can recently be regulated by the transmission of regulating the motor revolution or regulating belt pulley, and the vibrating deflection of each section compass screen surface can be determined to the angle of the line in the line in rotating shaft axle center and each rotating shaft axle center by the splicer axle center is set.
Compared with prior art, the present invention has following beneficial effect:
1, mass of vibration of the present invention is little, and energy consumption is low;
2, compass screen surface of the present invention can adopt the multistage combination, easily realizes maximizing;
3, adjustable parameter of the present invention is many, and amplitude, vibration frequency can both independent regulation;
4, compass screen surface body vibration of the present invention is even.
