The specific embodiment
Below in conjunction with embodiment, utility model is described in further detail.
Embodiment 1:
As Figure 1-4, the flip flop screen of the utility model that this is routine comprises casing 1, and described casing 1 comprises the biside plate parallel with described casing 1 axis; Described casing 1 comprises on vertical direction, upper and lower overlapping equal thick screen layer and flip flop screen layer; Described equal thick screen layer comprise with the described biside plate square beam being arranged in parallel 4 connected vertically and and be vertically set on the fixed screen deck of described square beam upper end; Described flip flop screen layer comprises with the described biside plate fixed cross beam being arranged in parallel 5 connected vertically, with the unsteady crossbeam 6 of described fixed cross beam 5 alternate settings be vertically set on described fixed cross beam 5 and the compass screen surface of unsteady crossbeam 6 upper ends; Described equal thick screen layer top is provided with described biside plate box excitation beam of vibration 7 connected vertically and is arranged on the box vibrator 8 on described box excitation beam of vibration 7, and described box vibrator 8 connects eccentric block and drive unit.
