For guaranteeing the vibrating effect of vibratory sieve, the eccentric direction unanimity of the eccentric orfice of above-mentioned driven pulley 6, adjustable eccentric piece 5, eccentric shaft 1.
For guaranteeing this vibrator reliability service, each movement parts sufficient lubrication, this vibrator also comprises oil fuel tube 17, drain line 16 and thermometric bar 18, described oil fuel tube 17 and thermometric bar 18 are located at respectively on the described end cap, described oil fuel tube 17 is communicated with the cavity of described cylindrical casing 7, described thermometric bar 18 tops are stretched into described end cap and are positioned at the end cap inboard, and described drain line 16 is located at described cylindrical casing 7 bottoms and is communicated with the inner chamber of cylindrical casing 7.This vibrator cylindrical casing 7 inner chambers can inject lubricating oil by oil fuel tube 17, guarantee the lubricated operation of each movement parts; And can be by the lubricating oil of drain line 16 replacing cylindrical casings 7 inner chambers behind equipment operation some cycles or lubricant pollution; The lubricating oil of thermometric bar 18 monitoring cylindrical casings 7 inner chambers is used for early warning vibrator fault.
For further guaranteeing the sealing of cylindrical casing 7 inner chambers, this vibrator also comprises two labyrinth lids 14, described two labyrinths lid 14 be placed in respectively on described eccentric shaft 1 axle journal and with eccentric shaft 1 axle journal interference fits, described two labyrinths lid 14 lays respectively at two end cap 4 outsides and cooperates with end cover clearance.
Seal 10 and 11 between above-mentioned end cap 4 and eccentric shaft 1 axle journal, between shoulder disk 8 and the bearing block 2 can adopt the O-ring seals sealing.
During the work of this vibrator, adopt motor to connect in the driven pulley at eccentric shaft two ends one by belt so that vibrator power to be provided, because the eccentric orfice of driven pulley is connected with eccentric shaft by flat key with the adjustable eccentric piece, therefore drive the eccentric shaft rotation, eccentric shaft eccentric orfice with driven pulley in rotation is made the circle orbiting motion around the driven pulley center, so eccentric shaft drives bearing block by the circle orbiting motion, because the vibratory sieve two side is fixed on the bearing block, so the circle orbiting motion is made with bearing block in the vibratory sieve two side, this circle orbiting motion amplitude is by the degree of eccentricity of driven pulley eccentric orfice, the degree of eccentricity of eccentric shaft and the decision of the barycenter of eccentric block, the motion of vibratory sieve two side drive the screening processing that vibratory sieve is made circle track vibration realizing material; The round track vibration of vibratory sieve imposes enough normal forces and tangential forces and makes reasonable compatibility by adjusting the adjustable eccentric piece the material on material bed plane on the screen cloth, has guaranteed effective screening of material, and is especially effective equally at the higher material of humidity.
The adjustable eccentric piece can adopt round eccentric block in this vibrator, the recess of some band screws be can have on it, matter piece, i.e. metal weights piece in some recesses, increased or reduce by bolt, thereby change the quality of adjustable eccentric piece, to adjust the eccentric throw and the rotary inertia of eccentric block; So according to the technological parameter of vibratory sieve, normal force and tangential forces that screen cloth is acted on the material are made reasonable compatibility, and adjust the vibratory sieve amplitude, reach good screening effect.
Theoretical design of plane motion inertia-type off-resonance mechanical kinetics during the utility model is learned according to vibrating machine adopted the vibratory sieve high efficiency of this vibrator, is difficult for the material plug-hole, especially is difficult for making wet material plug-hole.The vibratory sieve of its relative twin shaft circular vibration track does not have synchronizing wheel and synchronous band, only with a Motor Drive, more need not consider the homophase parallactic angle after twin shaft makes up, the problem of rotating in the same way, working asynchronously.The synchronizing wheel that has not particularly had vibrator both sides is different with driven pulley, solves because of the different different problems of rotary inertia that cause of above-mentioned both shapes thereby save.From its mechanical characteristic, the relative twin shaft of whole sieve of single shaft circular vibration track laterally rocks greatly during its vibration and reduces, and has promptly improved the stability of vibrator and vibratory sieve operation.
This exciter structure is simple, and runnability is stable, and diligent performance is good, and the work energy consumption is low, and equipment manufacturing cost is cheap, is widely used in the material screening operation of all kinds of middle-size and small-size vibratory sieves.
