Abstract

The utility model belongs to the material crushing equipment, mainly comprising a fixed jaw, a moving jaw and a crushing chamber composed of the moving jaw and the fixed jaw. The upper part of the moving jaw in oblique arrangement is a movable jaw plate with a convex face. The middle position at the lower part of the moving jaw is connected with an unbalance exciter. The fixed jaw plate with a concave face and the moving jaw with the upper part provided with the movable jaw plate form an inclined curve crushing chamber. The movable jaw plates are provided with screen meshes. The utility model can reduce the height of the material inlet of the crusher and reduces equipment investment. The crushing ratio of the curve crushing chamber can be raised by 2-3 times. The screen meshes on the movable jaw plate can effectively reduce over-crushing by 50-70 percents.

Description

Vibration oblique jaw type curve cavity disintegrating machine

The utility model belongs to the material disintegrating apparatus, mainly proposes a kind of vibration oblique jaw type curve cavity disintegrating machine.

In existing vibration jaw crusher and the domestic and international conventional jaw crusher, all adopt the vertically arranged crusher chamber of linear pattern or broken line type, in order to bite bulk materials and the big ratio of reduction to be arranged, often can't realize, for reaching instructions for use, often requiring to adopt several sections disintegrating machine series connection to use just can finish, the crusher chamber that system is comparatively complicated, simultaneously vertical, feeding mouth is on the top of disintegrating machine, the conveying equipment that makes feed is (as belt conveyer, apron conveyor) also longer, higher, the fragmentation that is used under the mine is also difficult, when making combined type crushing and screening unit, make device dote on greatly, often need be designed to several sections.General jaw crusher when some specific uses (as broken railway, highway coal with stone, coal preparation plant, these all do not need too many fine grained but are even more good more when reaching qualified) existed pulverizing toward contact, make it to reach requirement and be used as that refuse is processed to fall, wasted material.

The vibration oblique jaw type curve cavity disintegrating machine that the utility model proposes promptly provides a kind of large reduction ratio, and the disintegrating machine of low dwarf forms can allow the particle of qualified size discharge fast simultaneously in order to solve above-mentioned deficiency, in order to reduce the problem of pulverizing.

The utility model is finished the technical scheme that its goal of the invention takes: it has the moving jaw that top is the sewing jaw of convex surface, fixed jaw, a uneven vibrator of band concave surface by what be obliquely installed, formations such as frame, the top of moving jaw and the sewing jaw of convex surface connect as one, the middle part of bottom and uneven vibrator link, the fixed jaw of band concave surface and the common shaped form crusher chamber that constitutes an inclination of the sewing jaw on moving jaw top, the end positions of moving jaw bottom is connected on the frame by shock-absorbing spring, and fixed jaw and frame connect firmly.

Can require to set sieve aperture according to fragmentation on the sewing jaw, to reduce pulverizing.

The utility model adopts the crusher chamber of inclination, can make the disintegrating machine feeding mouth height of same type specification descend 30～40%, make the diaphragm extension set group, fixedly the height of Crushing Station descends, reduces the height of factory building, reduces the investment of relevant device, also can be used for the crushing operation of sub-terrain mines simultaneously.

The utility model adopts the shaped form crusher chamber, makes the angle of the tangential direction on the plumb cut of any one crusher chamber reach minimum state.The position that has can even be zero, thereby can effectively bite material, is unlikely to skid, when bigger feed or circular granular, the bigger ratio of reduction is equally arranged, can improve 2～3 times of the ratios of reduction, reach 4～20, in actual production, can reduce the hop count of crushing system, reduce the equipment investment of system.

Sieve aperture on the sewing jaw can make qualified material discharge as early as possible, can effectively reduce to pulverize to reach 50～70%, increases output 20% simultaneously.

The accompanying drawing that the utility model embodiment provides is:

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is another structural representation of the utility model.

The embodiment that provides is in conjunction with the accompanying drawings further specified the utility model:

As shown in drawings, sewing jaw 11 with convex surface connects firmly with moving jaw 1 top, moving jaw 1 lower middle position is the uneven vibrator 2 that connects firmly, two ends are by damping elastomer element 7, seat is on frame 9, and fixed jaw 8 and frame 9 with concave curvatures are fixed on one, and the sewing jaw 11 of the fixed jaw 8 of band concave surface and band convex surface constitutes the shaped form crusher chamber A that the cross section from top to following progressively diminishes jointly, its upper opening is material inlet B, and lower openings is discharge gate C.

Motor drives uneven vibrator work by transmission device, produce uneven exciting force, drive sewing jaw 11 work, produce the displacement of a relative origin-location, make the volume of crusher chamber A periodically become big and dwindle, enter the material of crusher chamber A from material inlet B, when crusher chamber A diminishes, impacted, extruding and densification, material is subjected to periodic fragmentation power, material is progressively weakened, and intensity progressively diminishes, and discharge from discharge gate C the back that to the last is broken.

As shown in Figure 2: comparing with accompanying drawing 1, is to have set sieve aperture D on sewing jaw 11, and the material of crusher chamber A can be discharged by sieve aperture D as early as possible as reaching qualified composition, pulverizes and energy consumption to reduce unnecessary crossing.

Claims
