the filter cloth supporting rod 9 which is impacted and vibrated by the vibration beam 2 to jack up generates upward bounce in the falling guide groove 8 of the supporting frame 7, and the bounced upward filter cloth supporting rod 9 is higher than the top surface of the vibration beam 2;
the vibration beam 2 falls back in the limit seat 4 due to gravity;
the filter cloth supporting rod 9 falls back down in the falling guide groove 8 of the support frame 7 due to gravity, and the filter cloth supporting rod 9 falling back down impacts the bottom of the falling guide groove 8 of the support frame 7 to form secondary impact vibration.
