Novel vibrating screen
Technical field
The present invention relates to the instrument vibratory sieve, particularly have straight-line oscillation and vertical vibration concurrently, and the big large-scale vibrating screen of vertical vibration amplitude.
Background technology
Existing industrial vibratory sieve, generally adopting motor is power, through the transmission of belt reducing gear; Driving contains the four-bar mechanism of moving sets; Wherein, a side link is a crank, and another side link is the toggle (also claiming eccentric shaft mechanism) of guide rod; Make screen frame do straight reciprocating motion, promptly become the screen frame straight reciprocating motion of (containing sieve plate) to the rotation of motor.
The defective of existing vibratory sieve mainly contains: can not maximize; Floor space big (crank linkage driving system is offset to the sieve plate side); Have that noise is big, power consumption is big and can not form vertical vibration or the vertical vibration amplitude is little, finally cause the relatively poor problem of screening effect.
Summary of the invention
The purpose of this invention is to provide a kind of existing reciprocating motion, again the bigger novel vibrating screen of vertical vibration and vertical amplitude arranged.
The objective of the invention is to realize like this: a kind of novel vibrating screen comprises motor, belt gear; Eccentric shaft mechanism, screen frame and sieve plate, eccentric shaft mechanism is arranged on screen frame middle part lower position; Move left framework be symmetricly set on eccentric shaft mechanism and arranged on left and right sides identically, wherein, move left and be hinged with two connecting rods between framework and the eccentric shaft mechanism with the frame structure that moves right; Move left and be fixed with a plurality of slideways that are used as with main body frame formation straight line moving sets on the framework, move left and be provided with a plurality of compound forks between framework and the screen frame, compound swing rod structure is: the fork upper end is hinged on the upper pendulum bar seat; The fork middle part is hinged on the middle swing rod; Fork lower end and small rod one end are hinged, and the small rod other end and base are hinged, and base is fixed on and moves left on the framework; Middle swing rod is fixed on the main body frame, and the upper pendulum bar seat is fixed on the screen frame.
Also be provided with the exciting rubber parts between the junction surface of above-mentioned screen frame and main body frame.
Also be provided with a plurality of damper mechanisms between above-mentioned screen frame and the main body frame; The damper mechanism structure is: surrounded by following angle bar and last angle bar and form a rectangular chamber; Be fixed with four rod members on the inferior horn iron bottom plate, the bearing activity is set on four rod members, and is set with two springs on each rod member; Two springs lay respectively at the above and below of bearing; The upper end that each rod member stretches out the angle bar top board is connected with locknut, and the swing arm lower end is fixed on the bearing, and the swing arm upper end fixes with screen frame.
Be respectively arranged with ball bearing on the fork lower end of above-mentioned compound fork and the base, the small rod two ends connect firmly respectively on the axle of above-mentioned two ball bearings.
The structure of above-mentioned eccentric shaft mechanism is: by first eccentric shaft that is installed on the bearing block; Second eccentric shaft and the 3rd eccentric shaft connect composition in order through shaft coupling; Wherein, First eccentric shaft and the 3rd eccentric shaft are by same axis setting, and the parallel axes of second eccentric shaft departs from the axis of first eccentric shaft.
Compared with prior art, the present invention has following characteristics and advantage:
1, vibratory sieve maximizes
The modularization theory: vibratory sieve maximization technical barrier has not existed.
2, noise is little
Low-noise structural: vibratory sieve no longer is the synonym of noise.Adopt damper mechanism and (abnormity) exciting rubber parts (between mobile framework and main body frame), effectively reduce the vibratory sieve running noise.
3, save the energy
Moving sieve formula design: 1/3 above energy saving has become possibility.
4, the screen frame existing reciprocal translation of moving has vertical vibration again
The transmission mechanism of screen frame adopts exclusive compound swing rod structure, and have the advantages that to strengthen large amplitude: vertical amplitude can be accomplished more than the 15mm.
5, screening effect is better
Sieve plate time vibration: dehydration, de-mediated be the strong guarantee of excellent results more.
6, variable ratio frequency changer drives: let the user set the optimum operation effect.
