The present invention has three large key structural feature:
1. a pedestal is set, frame (disintegrating machine) and vibration envelope are combined into one (being connected to above and below pedestal);
2. pedestal is connected on stand by elastic supporting mechanism;
3. a pair gear is separately positioned on two eccentric shafts, and two gears engage each other running.
Of the present invention opening one's minds is:
(1) general plotting: disintegrating apparatus and screening plant are that its core component is all containing " axle of bias " along the visual plant connecing operation in crushing production line.Imagine and fragmentation and screening two equipment are united two into one, share " axle of bias ", be designed to " crushing and screening all-in-one ", utilize same " eccentric shaft ", both produced broken stroke and completed crushing operation, produce again shock motion and complete screening operation.
(2) details design: be divided into following three kinds of situations;
(1) in prior art, jaw is broken has single eccentric shaft structure { as the single-shaft double-crank-rocker mechanism disintegrating machine (as shown in Figure 2) that conventional jaw crusher (as shown in Figure 1) and the applicant declare, number of patent application is 201110092010.9}, vibratory sieve also has one-eccentric rotor type vibrator vibratory sieve (as shown in Figure 3, it is circular motion track).The present invention describedly can be designed to " altogether single shaft crushing and screening all-in-one " by upper;
(2) in prior art, jaw is broken has again double-eccentric shaft structure (as the dual-spindle dual-crank rocker mechanism disintegrating machine (as shown in Figure 6) that the applicant declares, number of patent application is 201110092031.0), vibratory sieve also has double-shaft vibration exciter vibratory sieve (as shown in Figure 7, it is straight-line trajectory).The present invention describedly can be designed to " altogether double-shaft crushing screening all-in-one " (required direction of excitation Angle Position is transferred at the phase angle of disintegrating machine double-eccentric shaft, is not affecting under disintegrating machine behavior pattern, meeting the feature request of vibrator) by upper;
(3) in prior art, vibratory sieve also has three axle vibrators (elliptical trajectory), and jaw is broken but without three eccentricity axle construction.But another innovation bright spot of the present invention is: the twin shaft of vibratory sieve is designed to eccentric structure small one and large one, be elliptical trajectory " altogether double-shaft crushing screening all-in-one " (twin shaft of vibrator is designed to small one and large one and also can produces elliptical orbit exciting effect) equally.
Core technology of the present invention: by " eccentric shaft " in crusher and " vibrating shaft " work " coaxial " Integral design in vibratory sieve equipment, realizes " crushing function " and " screening function " with machine integrated.
By arranging a pedestal, disintegrating machine is arranged on above pedestal, the core component of vibratory sieve " vibrator " is removed, remaining " vibration envelope " is arranged on below pedestal, disintegrating machine and vibratory sieve are connected.
Like this, " eccentric shaft " (no matter being single shaft or twin shaft) of disintegrating machine, is also vibratory sieve " vibrating shaft " simultaneously, namely does the broken work done of eccentric stroke, does again exciting screening work done." fragmentation " and " screening " two operations are jointly completed by it.
The most significant functional character of the present invention is " energy-conservation ".It is not energy-conservation on conventional meaning, but very special energy-conservation----almost eliminate the energy-conservation of screening work done energy consumption completely, be significantly energy-conservation!
The analysis of Energy saving mechanism of the present invention:
On the surface, two machines that are broken and that sieve or two functions seemingly merge by the present invention, but inherently see really not so.Because:
1. so-called vibratory sieve and disintegrating machine unite two into one.But this core component of vibrator removed by vibratory sieve, only " vibration envelope " these parts have not belonged to the vibratory sieve in equipment meaning;
2. so-called crushing function and screening function merge, in fact also not so." screening " of the present invention not only not wasted work, on the contrary in help disintegrating machine " weakening ".
Technological innovation bright spot of the present invention, is just that becoming " fraud " is " profit "." bias " motion of disintegrating machine eccentric shaft, while generation broken " stroke " completes crushing operation, also produce the drawback of " vibration ", people are overcoming this " drawback " by fair means or foul.The present invention utilizes this " drawback " to carry out screening " work done ", becomes fraud into profit.
From amechanical angle analysis, its " energy-conservation " mechanism is more clear.The vibration source of jaw crusher has two, and one is the eccentric rotary inertia force because eccentric shaft causes; Two be because of dynamic jaw wave cause wave inertia force.
Overcome eccentric rotary inertia force easy, utilization is set up " eccentric block " and is balanced, and on flywheel, usually adds " eccentric block " so that balance in reality.The self-balancing eccentric shaft technology of the applicant's invention is another kind of new equilibrium pathway (application number is 201110092031.0).
Overcome that to wave inertia force just more difficult, it should follow the law of conservation of momentum of mechanics, and equation of equilibrium is m1v1=m2v2.In formula, m1 is dynamic jaw quality, and v1 is dynamic jaw speed; M2 is frame quality, and v2 is gantry speed.Be v2=m1v1/m2 after above-mentioned formula distortion, from this formula, overcome vibration force (i.e. nosing force) is exactly allow gantry speed diminish.Its measure is nothing but 1. allow jaw quality diminish; 2. allow jaw speed diminish; 3. allow frame quality become large.
Dynamic jaw speed is little just means that broken work done diminishes, and affects crushing efficiency; Dynamic jaw quality diminishes and has limitation, and dynamic jaw need have enough intensity, rigidity and quality, can not be too little; Organic frame quality becomes and is only greatly the effective approach of reality.
Technical measures of the present invention are just to increase frame quality.On the one hand, strengthening frame quality (namely strengthening m2) can vibration damping weakening effectively (namely reducing v2); On the other hand, dynamic jaw is in moving back and forth, and frame is done oppositely to move back and forth (namely vibrating), can produce vibration damping, is also helping vibration damping to move.In the present invention, sieve not only not wasted work, on the contrary in help weakening.Carrying out weakening by the approach allowing its work done create " profit " to go " fraud ", is the innovation of power-saving technology in crushing technology field.
" close coupled type crushing and screening all-in-one " designs, and is broken, material sieving technology field, and even the new exploration of technological progress in crushing production line technical field! Because its energy-saving effect is remarkable, so, be also an important power-saving technology innovation!
Except above remarkable result, the present invention also has following beneficial effect:
1. simplify number of devices, reduce manufacturing cost (remove exciter for vibration screen and power supporting after, the weight of vibratory sieve about alleviates 30 ~ 40%, and cost about reduces by 50 ~ 60%).
2. equipment of saving is from wasted work.Because prior art vibratory sieve needs to arrange exciter apparatus, so that huge structure (large with material), heavy from stature, from wasted work large (accounting for 20%), after removing vibrator, except about economizing except merit 20%, be omitted the input cost of a conveying equipment and run power consumption.
3. simplify crushing production line flow process, be convenient to installation, care and maintenance.The fault about 90% of vibratory sieve occurs in vibrator assembly, after having removed vibrator (only remaining envelope), except changing wear-out part, there is mechanical breakdown hardly.
4. pair old product transformation is convenient.
5. floor space is little.
6. function is concentrated, unit operation, easy to use and management.
