Description
The present invention relates to disintegrating apparatus.
Equipment of the present invention for fractured rock of great use, this will be described in detail in conjunction with the application.And this equipment is for broken other material (as glass, ore, fragment of brick, pellet) also of great use.
At present, carry out broken equipment polytype is arranged: a ball mill, rod mill, hammer-mill and jaw crusher.Yet, to " accurately " fragmentation, just with the material fragmentation obtaining the particle in a strict size range, and fines is less, usually adopts jaw crusher.To be jaw crusher carry out fragmentation-a moving jaw swing with the mode of action of hammer anvil to the most frequently used structure hits to one and decide jaw.The position-adjustable of deciding jaw changes minimum clearance between jaw.This disintegrating machine effect is fine, but quite wastes power, is absorbed because the strength of most moving jaw decides jaw, and is not used in broken material.Therefore, this equipment needs a very heavy base, bears the uneven load that is added on by the impact of deciding jaw on the equipment.This jaw crusher illustrates and is described in No. 227301, Australian Patent and the United States Patent (USP) No. 2326316 and No. 4124170.
Several existing patents all attempt to solve this problem with the crusher structure that two jaws all drive.For example No. 427441 U.S. Patent Publications a kind of disintegrating machine, the jaw of two positioned vertical is arranged, gapped between the two, each jaw is near its base position swing.Two jaws are driving by this sample loading mode near its upper end, make their swings simultaneously in the same direction, make between jaw material squeeze to roll between two jaws and stand to mill and fragmentation, and this is because the relative motion of crusher surface, and one upwards and another is downward.A major defect of this structure is that the material between jaw is to mill between jaw rather than impacted by two jaws, and this has just weakened the impulsive force that jaw can be brought into play greatly.Also have, greatly for the power dissipation that drives two jaws in moving up and down jaw, rather than make jaw hit the material of wanting broken.
United States Patent (USP) discloses a kind of disintegrating machine No. 472367, and it has a pair of relative their lower end of jaw to shelve on supporting roller to roll.Two jaws by eccentric drive in opposite directions with from, like this, a jaw always moves comparatively fast with respect to another, and the continuous earthquake of this apparent surface to jaw.Yet, this eccentric motion means two jaws and impacts the material of wanting broken incoordinately, and this structure also has other shortcoming, the roller of two jaws is installed the lower end that has fettered two jaws and can only be rested on same position exactly, and mean two jaws can not free pendulum the action parallelogram motion, cause side load on the jaw to be directly passed to the supporting casing of disintegrating machine rather than absorbed by jaw itself.
No. 472367, a lot of aspects of structure of a kind of disintegrating machine that No. 3079096, United States Patent (USP) is announced and United States Patent (USP) similar, its a pair of jaw sets up in the lower end and vibrates, and the lower end of each jaw is by an elastic support supporting and retrain.In use, two jaws be subjected to vibration in opposite directions with from, but can not free pendulum the action parallelogram motion, so this structure also has the sort of shortcoming of No. 472367 descriptions of pair United States Patent (USP).
In the effort that overcomes above-mentioned shortcoming, the applicant has designed a kind of disintegrating machine that becomes No. 196191 patents of New Zealand, it has a pair of relative broken jaw of installing swingably to make them to freely swing by a parallelogram mode from side to side, so just avoids main reaction force is passed to the supporting casing.Two jaws by one near the free-ended suitable drive mechanism of jaw drive simultaneously in opposite directions with from.Found that this structure is very satisfactory in many application, but (particularly when more broken its size of gravels approaches the receptible full-size of this disintegrating machine institute) finds also some deficiency of this disintegrating machine in some applications.Especially, maximum sized or require more uniform fragmentation is arranged along the whole length of jaw near maximum sized gravel.Also have, moist material is blocked between two jaws easily and is difficult for removing.
An object of the present invention is to provide a kind of disintegrating machine that overcomes the above-mentioned shortcoming of prior art disintegrating machine, specifically, the invention provides a kind of disintegrating machine, it has all advantages of the disintegrating machine of No. 196191, new zealand patent, and also has additional advantage, thereby owing to make broken function on each jaw total length, carry out total breaking capacity that fragmentation has improved this disintegrating machine, with and the jaw material that can move by this way and be blocked between two jaws to remove.
The invention provides a kind of disintegrating machine, comprise a pair of relative broken jaw, each jaw be installed on swingably carry out on the supporting arrangement in opposite directions with from swing; The pivot holder of each jaw is near an end of this jaw, and this end of this two jaw is settled relatively, and the other end of this two jaw is also settled relatively; First drive unit is used to drive the swing of this two jaw, simultaneously in opposite directions simultaneously from, also can make the two jaws while towards equidirectional swing simultaneously; This end that second drive unit is used to drive at least one jaw towards and leave this end of another jaw.
Preferably arrange above-mentioned two jaws to make and form a wall of facing mutually of the hopper of convergence downwards.
This end of above-mentioned two jaws can be settled near the top of disintegrating machine, and their this other end is then near the disintegrating machine bottom.Also this other end of two jaws can be settled and the close disintegrating machine of this end bottom near the disintegrating machine top.
First drive unit can comprise a unified drive unit, perhaps two drive units independently, and every jaw connects one.
Can drive in this ends of two jaws one or two, if drive two, above-mentioned second drive unit can be an independently drive unit of a unified drive unit or two.
First and second drive units can be independently or the phase mutually synchronization.
By way of example, reference accompanying drawing most preferred embodiment of the present invention is described: wherein
Fig. 1 is the end-view of equipment of the present invention,
Fig. 2 is the side view of Fig. 1 equipment, has removed the part rack component,
Fig. 3 is the cutaway view of III among Fig. 2-III tangent plane,
Fig. 4 is the partial end view of Fig. 3, and
Fig. 5 is the cutaway view of V among Fig. 2-V tangent plane,
Referring to accompanying drawing, rock breaking device comprise one top 11 and leg 12 arranged lift shape frame 10.On frame top 11, install two pairs of broken jaw trunnion bearings 13,14.Two pairs of gantry posts 13,14 are being striden table top 11 relative to each other.Two jaws 15,16 are faced mutually, and each jaw 15,16 has a trunnion axis 17,17a, respectively stretch from every limit, jaw upper end; Each 17, the termination of 17a is fixed on the oscillation bearing 13,14 swingably.Therefore, two jaws 15,16 of disintegrating machine are suspended relative to each other from the table top 11.
The axle 17a that connects jaw 16 also props up on a pair of capacity eccentric bearing 40, and capacity eccentric bearing is pressed the close part (Fig. 5) that known way connects jaw 16 back.
Other possible structures (not illustrating) are to replace axle 17 axle 17a to be contained on the capacity eccentric bearing, and perhaps diaxon is all equally eccentric installs, make jaw 15,16 have one or two to be driven and make eccentric motion, near two jaw upper ends in opposite directions with from.Also can be without capacity eccentric bearing, and axle 17,17a can have one or two all to do eccentric shaft, provide the required eccentric motion of jaw 15 and/or 16 upper ends.
The most handy wear-resistant block 18 of the inner surface of crushing jaw is protected, and can do many ribs 19 on its working surface.The height of rib can reduce towards an end.The interior crusher surface of wear-resistant block 18 can be inlayed with hard alloy steel and be reduced wear.
Wear-resistant block 18 can by fix, be spirally connected or other method stuck-at-5,16 on, and can turn.
The top of jaw 15,16 is wideer than the bottom, and is welded with two vertical end walls 20,21, end wall of the end side weld of each jaw, and the free end of each end wall 20,21 is near the adjacent end edges of another jaw 15,16.Like this, jaw 15 and end wall 20 move together, and jaw 16 and end wall 21 move together, and this layout has formed end wall and jaw, the charging hopper of " V " shape.When disintegrating machine moves, broken material to put into the top of hopper, under the effect of gravity, fall, and under broken state, leave the bottom of disintegrating machine by disintegrating machine.
The lower end of two jaws 15,16 is coupled together by a reciprocator, and two broken jaws are swung simultaneously around its trunnion bearing 13,14.Reciprocator can merge simultaneously two jaws to separate simultaneously; Each jaw is with same strength exercise.Reciprocating motion is to be provided by the off-centre on the driving shaft 23 22, and driving shaft flatly is installed on two bearings 24 on the outer surface that is fixed on jaw 15 lower ends, and bearing is the width that driving shaft 23 extends beyond jaw 15, and has two connecting rods 26 to be contained on eccentric 22.The other end of connecting rod 26 is installed on the rotor journal 27 of same setting on the transverse axis 28, and transverse axis flatly is contained on the bearing 29 of the lower end of being fixed in another jaw 16, is parallel to the driving shaft 23 on the jaw 15.
A V belt driving wheel 30 is fixed on the termination of driving shaft 23, and this belt pulley 30 is driven by known way by a motor (not shown).When belt pulley 30 was driven, it made and drives 23 rotations, and the rotor journal on the axle 23 makes jaw 15 be flapped toward and put from jaw 16 like this.
Simultaneously, connecting rod 26 is because the effect of axle 23 is reciprocating, and makes jaw 16 be flapped toward and put from jaw 15.Connecting rod 26 and axle 23 be designed to make like this two jaws 15 with 16 simultaneously from and move toward one another, each jaw moves with same speed.
Normally in service, connecting rod 26 relative rotor journals 27 do not move, but are clamped on the axle 28 by the clip that is fixed on the connecting rod 26, and available screw 32 unclamps from axle 28.When axle 28 unclamped, it can be at the connecting rod 26 inner components of rotation, and rotor journal 27 comes the wheelbase of regulating shaft 23 and 28 by this, thereby can change the gap between two jaws, 15,16 lower ends, and then clip 31 is tightened.
The distance of two jaws, 15,16 upper ends also can change, and irrelevant with two jaw lower ends, for example can unload the bolt of lower bearing 13,14 from table top 11, utilizes bolt hole (not shown) different on the table top 11 to locate them again.
If without rotor journal 27, also can change the distance between two jaws, 15,16 bottoms with the connecting rod of adjustable-length, for example with the form that right-and-left threaded stretcher is arranged.
In some occasion, also can be conversely illustrated layout, though hopper still attenuates down, the upper end of two jaws 15,16 is reciprocating, and the lower end of two jaws is contained on the frame swingably, eccentric drive is made in one or two this lower end.
An important feature of the present invention is that two jaws 15,16 can be swung by parallelogram motion around trunnion bearing 13,14, and on-fixed is extremely on crusher frame.In order to realize this point, driving shaft 23, belt pulley 30 and connecting rod 26 can both be swung with jaw, and since from the motor to the belt pulley 30 driving belt (not shown) be flexible, it can not limit the motion of jaw.The performance that two jaws 15,16 can be swung by the parallelogram mode simultaneously, avoided main reaction force to drop on the crusher frame therefore in the disintegrating machine running, most of active force of each jaw sends to and will carry out broken material, rather than pass to the jaw on its opposite, and do not have great power to pass to crusher frame, and only transmit by bearing 13,14.Thereby the moving both vertically of the center of gravity of (not considering the eccentric drive of jaw 15,16 upper ends) each jaw assembly, with its horizontal movement compare just do not have much.Like this, do not have great vertical vibration power to pass to frame 10, and the horizontal force major part is balanced and offset, therefore, improved the efficient of disintegrating machine greatly.Yet, the eccentric drive of jaw 15 and/or 16 upper ends causes the bigger component one of moving both vertically of this jaw, and this is beneficial to removing any material of jam-pack between two jaws because the jaw of each eccentric drive move downward the material that helps to smash and remove any of these jam-pack.
When illustrated embodiments of the invention in use, broken material to pour the top (for example from a feeding funnel) of disintegrating machine into.Two jaws 15 and 16 lower end swing simultaneously in opposite directions with also move prejudicially from, the upper end of jaw 15 towards and leave the upper end of jaw 16 and leave (perhaps, if two jaws all by eccentric drive, so, two jaws in the top in opposite directions with mutually liftoff motion).
The movement degree of the eccentric drive end of jaw or every jaw can be regulated with the orientation of adjusting capacity eccentric bearing 40.
The eccentric motion of the upper end of jaw or every jaw can the big gravel of precrushing, so just solved big gravel (approach disintegrating machine receptible full-size) and be extruded the problem of disintegrating machine during mutually near motion two jaws following, and by the upper end of jaw or every jaw eccentric motion produced adds fragmentation, also help to improve total crushing efficiency of disintegrating machine.As above institute's opinion, the eccentric motion of the upper end of jaw or every jaw also helps to eliminate the material of jam-pack between two jaws.
Though wishing two jaws 15,16 can swing by parallelogram motion, (its reason as previously mentioned) but to prevent a little will be desirable to this swing, when as needs, doing, can be with a spring assembly as elastomeric bushing 33 with two jaws 15,16 to the frame central location bias, be fixed on the cushion block 34 that is bolted on the leg 12.The lining inner core is fastened on one and turns round on the arm 35, turns round arm and is with the connecting rod of pivot to be connected with jaw 16 with one.This bias unit can not hinder two jaws to swing by the parallelogram mode, in addition this has been swung resistance inhibitor action and has helped two jaws are pushed to the center.
But the variation of above-mentioned disintegrating machine You various ways. At first, available any other the suitable driving of the driving of two E 15 and 16 upper and lower sides replaces, for example: but the replacement of the optical axis in the eccentric shaft 23 You Zhou neck Zhuan Zai capacity eccentric bearings, and optical axis 17 and capacity eccentric bearing 40 also can replace by the You eccentric shaft.
Secondly, the upper and lower side of each E can drive, replaces linkage driving; And the non-swinging end also of each E can drive by the suitable synchronous drive device of Yong independently of one another.
Its three, drive as using chain sprocket driving, gear drive or odontoid belt, the eccentric drive of E's or each E's swinging end is in step with the driving of the non-swinging end of each E.
