As seen from the above technical solution provided by the invention, the driving flip flop screen of floating frame that the embodiment of the present invention provides, owing to comprising fixing screen frame, float screen frame, elastic screen surface, shear spring and eccentric activator; The fixing compass screen surface crossbeam of screen frame and the compass screen surface crossbeam of floating screen frame are alternately arranged, and fixing screen frame 1 piece compass screen surface crossbeam more than floating screen frame, one end of elastic screen surface is fixed on the compass screen surface crossbeam of fixing screen frame, the other end is fixed on the compass screen surface crossbeam of floating screen frame, two screen frames are linked together by shear spring, described fixing screen frame is arranged in frame by shock-absorbing spring, and structure is simple, stable movement, vibrator stressed little, saving energy consumption, long service life, has practicality widely.
Accompanying drawing explanation
The structural representation of the driving flip flop screen of floating frame that Fig. 1 provides for the embodiment of the present invention.
Fig. 2 is the structural representation of floating screen frame in the embodiment of the present invention.
Detailed description of the invention
To be described in further detail the embodiment of the present invention below.
The driving flip flop screen of floating frame of the present invention, its preferably detailed description of the invention be:
Comprise fixing screen frame, float screen frame, elastic screen surface, shear spring and eccentric activator;
The compass screen surface crossbeam of described fixing screen frame and the compass screen surface crossbeam of floating screen frame are alternately arranged, and fixing screen frame 1 piece compass screen surface crossbeam more than floating screen frame, one end of elastic screen surface is fixed on the compass screen surface crossbeam of fixing screen frame, the other end is fixed on the compass screen surface crossbeam of floating screen frame, two screen frames are linked together by shear spring, and described fixing screen frame is arranged in frame by shock-absorbing spring.
Described eccentric activator is eccentric block or eccentric shaft structure, and its turning cylinder or eccentric shaft are arranged on the compass screen surface crossbeam of floating screen frame center of mass.
When the compass screen surface crossbeam of described floating screen frame is odd number root, the turning cylinder of described eccentric activator passes the compass screen surface crossbeam of the screen frame center of mass that floats and is arranged on this crossbeam;
When the compass screen surface crossbeam of described floating screen frame is even number root, described eccentric activator installs two groups, and symmetry is arranged on two compass screen surface crossbeams of contiguous barycenter in the middle part of floating screen frame, and is made the turning cylinder synchronous axial system of two groups of eccentric activators by toothed belt transmission.
The driving flip flop screen of floating frame of the present invention, compensate for the deficiencies in the prior art, structure is simple, energy consumption is low, stressed little, the failure rate is low of vibrator.
During work, the screen frame that floats makes circular vibration under the direct effect of eccentric activator, meanwhile, fixing screen frame produces additional elliptic vibration under the effect of vibration of floating screen frame, thus makes two screen frames do rightabout vibration, be in Near resonance oscillating state, between the adjacent compass screen surface crossbeam of two screen frames, alternately, elastic screen surface moves, when elastic screen surface is tightened in the intercropping tension and relaxation of the adjacent compass screen surface crossbeam of two screen frames distance, the acceleration that material obtains is very large, is conducive to material layering and thoroughly sieves.
Beneficial effect of the present invention:
The driving flip flop screen of floating frame provided by the invention, based on the operation principle of flip flop screen, utilizes eccentric activator Direct driver to float screen frame, elastic screen surface is moved in the intercropping tension and relaxation of the adjacent compass screen surface crossbeam of two screen frames; Fixing screen frame and floating screen frame are linked together by shear spring, and structure is simple, compact; The compass screen surface crossbeam of floating screen frame adopts hollow-pole charge structure, and screen frame quality of floating is relatively little, and required exciting force is little, and energy consumption is low; The turning cylinder of eccentric activator passes the compass screen surface crossbeam of the screen frame center of mass that floats and utilizes bearing to be fixed on compass screen surface crossbeam two ends, is connected with drive motors by belt transmission, and drive system is simple, failure rate is low.
Specific embodiment:
