Technical field
The utility model relates to the jaw crusher technical field, the jaw crusher of a kind of tool selective crushing function of more specifically saying so.
Background technology
Jaw crusher, it is broken to be commonly called as jaw, forms broken pair by moving jaw and two jaws of quiet jaw, and two jaw movements of simulated animal are accomplished the disintegrating machine of material crushing operation., low cost of manufacture simple in structure because of it, operation and maintenance are convenient, are to originate from early, use one of disintegrating apparatus more widely.
The broken weak point that exists of the jaw of right prior art:, lack the Cracking Mechanism of favourable selective crushing owing to receive the restriction of mechanism.
So-called selective crushing is exactly: the material internal organizational structure also not all is evenly abundant; More or less there is micro-cracks; If can select to set about carrying out fragmentation from the section part of these weak links, required crushing force is minimum, otherwise just the bigger crushing force of needs could be with its fragmentation.Selective crushing is good Cracking Mechanism, is the direction of being pursued in the disintegrating machine development.
The utility model content
The purpose of the utility model has been to break through that the prior art jaw crusher is congenital does not possess the limitation of " selective crushing " this Cracking Mechanism, and a kind of jaw crusher of tool selective crushing function is provided.
In order to reach above purpose; The utility model is realized through following technical scheme: a kind of jaw crusher of tool selective crushing function; Comprise frame, transmission device, double-crank endplay device and broken secondary; It is characterized in that crank and rocker mechanism and rear crank endplay device before described double-crank endplay device comprises; Moving jaw, preceding bracket and pre-eccentric driving shaft before preceding crank and rocker mechanism comprises; The rear crank endplay device comprises the moving jaw in back, back bracket and back eccentric drive shaft;
Described transmission device comprises preceding travelling gear, final drive gear and the drive that is arranged on frame lower, and preceding travelling gear is meshed with final drive gear and is connected on the drive;
The bottom of forward and backward moving jaw is articulated in respectively on the forward and backward eccentric drive shaft, and forward and backward eccentric drive shaft is connected with forward and backward drive respectively;
Moving jaw back side top before preceding bracket one end is articulated in, the other end are articulated in above the moving jaw front side, back, and back bracket one end is articulated in the moving jaw back side top in back, and the other end is articulated on the frame;
Broken pair comprises the fixed jaw and the sewing jaw that is arranged on the preceding moving jaw, the crusher chamber of the parallel cavity body structure of fixed jaw parallel face-off with sewing jaw formation that is arranged on the frame.
The primary structure characteristic of the utility model is: 1. inversion type twin shaft double-crank endplay device; What 2. laterally arrange is broken secondary.
The functional character that above architectural feature is brought is:
(1) function of the broken pair of parallel chamber type is the granularity concentration degree height of each discharging.It (is parastate during pilled-in selvedge that parallel chamber is set; But be " V " type during slack list), big up and small down when state is charging in the slack list, in constantly pushing and trembleing; Down compacting under the gravity effect; Be a tight parallel rectangular volume during to the pilled-in selvedge state, make material broken very carefully and very evenly (and positively fixed type double-crank rocker structure is down the broken motion feature of " V " shape chamber type, is unfavorable for the formation of lamination).
(2) the relative positively fixed type of inversion type twin shaft double-crank rocker structure has following advantage: 1. material is descending from top to down in the jaw crusher charging, and the horizontal stroke (broken stroke) to it requires up big and down small.But the characteristic of positively fixed type is little and big down on the horizontal stroke, and just in time opposite, inversion type has just satisfied this point.2. the forward and backward crank axle of inversion type is all in frame lower, and promptly center of gravity is low, helps the stable of equipment operation.
The mechanism of selective crushing is such: the internal organizational structure of material and not all even having no time, have micro-cracks or defective more or less, or closely dredge present situations such as irregular.If can select from the fragmentation of exerting all one's strength of these weak link parts, required broken work done just economizes most, and the material strength after the fragmentation the highest (defective in the interior tissue of particle has reduced a part).Otherwise just need the big crushing force could be with its fragmentation, and the material after the fragmentation kept original defective (even having increased defective), intensity be not good.
Realize " selective crushing ", satisfy two conditions: 1. being the process that material is in continuous pressurization, 2. is that the broken force of material constantly changes, and promptly material will constantly stir.
Above condition has been satisfied in the design of the utility model: at first; " the reinforcement effector function " of double-crank rocking bar machine provides superpower thrust (crushing force), produces the lamination effect down in " big stroke; little pilled-in selvedge " design again; The upper and lower continuous vibration of moving jaw before adding---make material constantly be in the state of rolling, promptly the broken impetus of material is constantly changing, thereby realizes selective crushing.
With parallel chamber is condition, and the reinforcement lamination motion through the vertical judder motion of preceding moving jaw and the level of the moving jaw in back " big stroke, little pilled-in selvedge " realizes that jaw broken " selective crushing " is the core technology of the utility model.
Under prior art, jaw is broken to be dried " heavy manual labour ", is again the broken type of typical individual particle, lets jaw broken realize " selective crushing " be that a great revolutionary character breaks through.Be the broken fines (even system sand) of beating of jaw and also become possibility.
As preferably, said before moving jaw perpendicular to ground configuration.
The function that moving jaw vertically is set is that moving jaw does not produce the horizontal direction crushing force before making, and only produces the vibration of vertical direction.
As preferably, transmission device comprises and is arranged on frame lower diameter one little big preceding drive and back drive.
The function of forward and backward drive variable speed is that the upper and lower beat frequency of moving jaw before letting is higher, leans on the moving jaw thrust in back to carry out the reinforcement fragmentation then.Before " upper and lower vibration " motion of moving jaw add synthetic common accomplish " selective crushing " of " big stroke, little pilled-in selvedge " motion of the moving jaw in back.
As preferably, fixed jaw and sewing jaw are the structure of lateral cross section undulate, and the deeply staggered and face-off of the protruding peak of fixed jaw and sewing jaw and trench forms the also crusher chamber of undulate of lateral cross section.
The major function characteristic that shear wave shape wave chamber shape is brought is the reinforcement effect.Promptly between two jaws, give a normal force, then produce a crushing force that has amplified in corrugated normal direction.Mechanical analysis is following, referring to accompanying drawing 4: because the structure of the moving jaw of fine crusher is movable in the vertical, so under drive shaft, produce thrust F1; But moving jaw is rigidity in the horizontal; Can not move, so can produce a deboost F3 in the horizontal, F1 and F3 synthesize F2; The F2 direction vector is the normal orientation of material, also promptly to the crushing force of material.Clearly F2 is greater than F1, so on material, can access one and amplify terrible broken kernel for one of sewing jaw energetically, this reinforcement effect is very useful to fragmentation.
In a word, the utility model designs with the vertical bar die cavity shape that the design of transverse wave die cavity shape replaces prior art, has not only changed the stress condition of material, has produced the reinforcement effect; And the waveform chamber is with respect to the vertical bar die cavity under the prior art (under same disintegrating machine width and crusher chamber width), and its chamber strip is longer, and constant, output are higher, and ten minutes is favourable.
As preferably, the length of fixed jaw and sewing jaw be moving jaw side long 1/4th to 3/5ths.
The jaw length of conventional jaw is basic very few with moving jaw side appearance difference, and the utility model jaw is set to short jaw.The function of short jaw is to be designed to material from advancing crusher chamber to going out the chamber, in the broken stroke to a material fragmentation once.It has broken through the conventional thinking of prior art " material advances crusher chamber through repeatedly stroke is broken ".
Short jaw is a new concept, new breakthrough.The prior art material advance the chamber go out the chamber will be through the repeatedly fragmentation of stroke.The utility model is designed to material and in a stroke, accomplishes just discharge of primary fragmentation.Being designed to broken work done to accomplish in the stroke is to let the centralized fragmentation of crushing force (ten chopsticks one foldovers of allusion are arranged, and frangible not divides that to be easy to fracture for ten times be a general knowledge).Under big stroke, material is made repeatedly continuous crushing in a stroke.
Short jaw is designed to material exactly and after each stroke finishes, promptly discharges.Because material is a freely falling body, jaw length is relevant with the broken rotating speed of jaw.Rotating speed is fast, and jaw is just short; Rotating speed is slow, and jaw is just long.
As preferably, a side of fixed jaw is provided with regulates the adjusting backing plate of fixed jaw with respect to the sewing jaw position.
In shattering process, jaw can be worn, thus the adjusting backing plate is set, can holding chamber shape constant, can better keep high efficiency broken.
As preferably, on the protruding peak of sewing jaw and the fixed jaw edge face vertical bar shaped tooth is set all.
The jaw of tape shape tooth has following two benefits: the one, and the jaw and the material contact-making surface of tape shape tooth are little, and broken pressure is big; The 2nd, utilize the bar shaped tooth realize " split broken, folding is broken, squeeze broken " etc. multiple broken mode of work-doing (when the tooth peak pushes material: material will be along the tip pressure effect and by splitting be called split broken; Material stress effect by bending and by jackknifing be called the folding broken; Material because of facial action of compressive stress squeezed split be called squeeze broken), to improve crushing efficiency.
As the alternative of such scheme, the trench place of sewing jaw and fixed jaw is provided with vertical row hole.
The function in the row hole that network structure is arranged is:
(1) realizes the shearing-crushing ability; The shearing-crushing function: material is in staggered position, both sides, receives the positive extruding in blade-like metal surface, just as scissor cut; When the shear stress intensity that material produces at stressed place reached the limit of, the material marginal portion was sheared and fragmentation.Because the anti-shearing stress-strength ratio compressive stress intensity of material is much lower usually, more produce effect than being in the crushing fragmentation so be in the fragmentation of shearing under the mechanism.
(2) wherein can withdraw from fragmentation in advance, make that fragmentation can be inexcessive less than the specification material of row bore dia.
