The present invention has three large primary structure features:
1. a pedestal is set, by frame (disintegrating machine) and vibration envelope be combined into one (above and below that is connected to pedestal);
2. pedestal is connected on stand by elastic supporting mechanism;
3. a pair of gear is separately positioned on two eccentric shafts, the intermeshing running of two gears.
Of the present invention opening one's minds is:
(1) general plotting: disintegrating apparatus and screening plant are the suitable visual plants that connects operation in crushing production line, and its core component all contains " axle of bias ".Imagination unites two into one fragmentation and screening two equipment, shares on " axle of bias ", is designed to " crushing and screening all-in-one ", utilizes same " eccentric shaft ", has both produced broken stroke and has completed crushing operation, produces again shock motion and completes screening operation.
(2) details design: be divided into following three kinds of situations;
(1) in prior art, jaw is broken single eccentric shaft structure { the single-shaft double-crank-rocker mechanism disintegrating machine (as shown in Figure 2) of declaring as conventional jaw crusher (as shown in Figure 1) and the applicant, 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 can be designed to by the above " single shaft crushing and screening all-in-one altogether ";
(2) in prior art, jaw is broken again double-eccentric shaft structure (the dual-spindle dual-crank rocker mechanism disintegrating machine (as shown in Figure 6) of declaring as the applicant, 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 can be designed to by the above " double-shaft crushing screening all-in-one altogether " (position, required direction of excitation angle is transferred to in the phase angle of disintegrating machine double-eccentric shaft, is not affecting in disintegrating machine performance situation, meet the feature request of vibrator);
(3) in prior art, vibratory sieve also has three axle vibrators (elliptical trajectory), and jaw is broken but without three eccentric shaft structures.But another innovation bright spot of the present invention is: by the twin shaft of vibratory sieve be designed to eccentric structure small one and large one, be " 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) of elliptical trajectory equally.
Core technology of the present invention: by " vibrating shaft " work " coaxial " Integral design in " eccentric shaft " in crusher and vibratory sieve equipment, realize " crushing function " and " screening function " with machine integrated.
By a pedestal is set, disintegrating machine is arranged on to pedestal top, the core component of vibratory sieve " vibrator " is removed, remaining " vibration envelope " is arranged on to pedestal below, disintegrating machine and vibratory sieve are connected.
Like this, " eccentric shaft " of disintegrating machine (no matter being single shaft or twin shaft) is also " vibrating shaft " of vibratory sieve simultaneously, does the broken work done of eccentric stroke, does again exciting screening work done.By it, jointly complete " fragmentation " and " screening " two operations.
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 exempted 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, the present invention seemingly merges two machines of broken and screening or two functions, but really not so from seeing in essence.Because:
1. so-called vibratory sieve and disintegrating machine unite two into one.But vibratory sieve has been removed this core component of vibrator, 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 wasted work not, is helping disintegrating machine " weakening " on the contrary.
Technological innovation bright spot of the present invention, is just that becoming " fraud " is " profit "." bias " motion of disintegrating machine eccentric shaft, when generation broken " stroke " completes crushing operation, also produces the drawback of " vibration ", and people are overcoming this " drawback " by fair means or foul.The present invention utilizes this " drawback " to complete screening " work done ", becomes fraud into profit.
From mechanics angle analysis, its " energy-conservation " mechanism is more clear.The vibration source of jaw crusher has two, and the one, the eccentric rotary inertia force causing because of eccentric shaft; The 2nd, because moving jaw waves the inertia force that waves causing.
Overcome eccentric rotary inertia force easy, use and set up " eccentric block " balance, in reality, conventionally on flywheel, add " eccentric block " so that balance.The self-balancing eccentric shaft technology of the applicant's invention is another kind of new balance approach (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 moving jaw quality, and v1 is moving jaw speed; M2 is frame quality, and v2 is gantry speed.After above-mentioned formula distortion, be v2=m1v1/m2, from this formula, overcome vibration force (being nosing force) is exactly to allow gantry speed diminish.Its measure is nothing but 1. to allow jaw quality diminish; 2. allow jaw speed diminish; 3. allow frame quality become large.
Moving jaw speed is little just means that broken work done diminishes, and affects crushing efficiency; Moving jaw quality diminishes and has limitation, and moving jaw need have enough intensity, rigidity and quality, can not be too little; Organic frame quality becomes and is only greatly effectively approach of reality.
Technical measures of the present invention are just to have strengthened frame quality.On the one hand, strengthen frame quality (strengthening m2) vibration damping weakening effectively (reducing v2); On the other hand, moving jaw is reciprocating motion, and frame does oppositely to move back and forth (i.e. vibration), can produce vibration damping, is also helping vibration damping moving.In the present invention, sieve not only not wasted work, helping weakening on the contrary.By the approach that allows its work done create " profit ", carrying out weakening and go " fraud ", is the innovation of power-saving technology in crushing technology field.
" close coupled type crushing and screening all-in-one " design, is broken, material sieving technology field, and even the new exploration of technological progress in crushing production line technical field! Because of its energy-saving effect remarkable, so, be also an important power-saving technology innovation!
Except above remarkable result, the present invention also has following beneficial effect:
1. simplified number of devices, reduced manufacturing cost (remove exciter for vibration screen and power supporting after, the weight of vibratory sieve approximately alleviates 30～40%, cost approximately reduces by 50～60%).
2. saving equipment is from wasted work.Because prior art vibratory sieve need to arrange exciter apparatus, so that huge structure (large with material), heavy from stature, from wasted work large (accounting for 20%), remove after vibrator, except approximately economizing merit 20%, also omitted input cost and the operation power consumption of a conveying equipment.
3. simplify crushing production line flow process, be convenient to installation, care and maintenance.The fault of vibratory sieve approximately 90% occurs in vibrator assembly, has removed (only remaining envelope) after vibrator, except changing wear-out part, has hardly mechanical breakdown.
4. pair old product transformation is convenient.
5. floor space is little.
6. function is concentrated, unit operation, easy to use and management.
