Example Embodiment
[0010] Floating frame driven type relaxation screen of the present invention, its preferred embodiment is:
[0011] Including fixed screen frame, floating screen frame, elastic screen surface, shear spring and eccentric exciter;
[0012] The screen surface beams of the fixed screen frame and the screen surface beams of the floating screen frame are alternately arranged, and the fixed screen frame has one more screen surface beam than the floating screen frame, and one end of the elastic screen surface is fixed on the screen surface beam of the fixed screen frame , the other end is fixed on the screen beam of the floating screen frame, the two screen frames are connected together by shear springs, and the fixed screen frame is installed on the machine frame by damping springs.
[0013] The eccentric vibrator is an eccentric block or eccentric shaft structure, and its rotating shaft or eccentric shaft is installed on the screen surface beam near the centroid of the floating scre...
Example Embodiment
Specific examples:
[0020] like figure 1 As shown, it includes a fixed screen frame 1, a floating screen frame 2, an elastic screen surface 3, a shear spring 4 and an eccentric vibrator 5. The screen beams 7 of the floating screen frame 2 pass through the holes on the side plate of the fixed screen frame 1 and are alternately arranged with the screen beams 6 of the fixed screen frame 1. The elastic screen surface 3 is installed on the screen beams 6 and 7, The fixed screen frame 1 and the floating screen frame 2 are connected together by a shear spring 4 , and the fixed screen frame 1 is installed on a frame 10 by a damping spring 9 .
[0021] like figure 2 As shown, the rotating shaft 8 of the eccentric vibrator 5 passes through the screen beam 7 near the center of mass of the floating screen frame 2 and is fixed on the beam through a bearing.
