Description

Annular crusher for massive materials

Technical field

The invention provides a kind of annular crusher for massive materials, specifically to be the annular weight that utilize to rotate hit fragmentation with especially big block abrasive material and mine, building material industry to emery wheel, grinding tool industry with especially big block building stones a kind of plant equipment.

Background technology

Various abrasive materials are as aluminium oxide, diamantane etc., are the main raw material(s)s of producing product such as emery wheel.These abrasive materials all are to make huge block semi-finished product through technologies such as oversinterings generally in process of production, and then through broken step by step, processing frustillatum finished product dispatches from the factory.

Since be the abrasive material of making product such as emery wheel, its hardness is very high certainly, and needed power is also very big certainly when therefore broken, and disintegrating apparatus commonly used has: single toggle jaw crusher, physical pendulum fine crusher, hammer mill and double-roll crusher or the like.Through the material after the three kinds of crusher in crushing in back, its granular size can reach the requirement of dispatching from the factory of product basically, and single toggle jaw crusher is respectively applied for the fragmentation of material each different phase from the bulk to the fritter according to the varying in size of charging aperture.

But even if large-scale single toggle jaw crusher, the material piece diameter that its charging aperture can allow generally also is no more than 500mm, and the block semi-finished product after the abrasive material sintering, and its material piece diameter even reaches 3000～5000mm generally all more than 1000mm.In addition, industries such as building materials such as cement are from stone material, the raw material of mining, and its size is often also big especially.Therefore, the semi-finished product abrasive material after the sintering or from the building stones of mining all can not directly enter common disintegrating machine and carry out fragmentation.

For addressing this problem, some enterprise once adopted crane to lift by crane a weight material was hit this method.But if weight is overweight easily pounds powdering with part abrasive material and building stones, price is had a greatly reduced quality; Weight is light, and then to hit cycle required when abrasive material and building stones are smashed more, and it is too low to adopt the lifting of crane repeated multiple times to hit production efficiency.Helpless, have to adopt the most original " manually swinging sledgehammer " this method, piece arrived fritter again during several meters big especially big smashed, till the common crusher in crushing of packing into.Whenever smash once, all will be through repeatedly hitting, production efficiency is too low, and working strength of workers is big especially.

At the problems referred to above, we have developed a kind of hammer type massive material crusher, and have applied for national inventing patent, and application number is: 201010109920.9.But, the crusher for massive materials that this patent relates to, peening hammer is not easy control along the axial wobble of gyroaxis during strike, and striking point is not accurate enough.

Take a broad view of industry present situations such as emery wheel, grinding tool and mine, building materials, be badly in need of a kind ofly reducing cycle as far as possible, alleviate efficient, the crusher for massive materials of labor strength being unlikely to material is pounded under the prerequisite of powdering, and striking point is accurate, and is reliable.

Summary of the invention

The purpose of this invention is to provide a kind of can addressing the above problem, and the axial location, strike process that can control percussion device crusher for massive materials accurately and reliably.Its technical scheme is:

Comprise base, drive unit, shaft coupling, percussion device and slideway, wherein percussion device comprises axle, bearing, bearing block, bearing pin, hit ring, the bracket I above the base is fixed in toggle mechanism and bottom, bearing block is by bolt I, nut I and packing ring I are fixed in the bracket I top, the axle two ends are installed in the bearing block by bearing, between bearing block the inner and the axle sealing ring is housed, bearing cap is fixed on the bearing block outer end by bolt II and packing ring II, the input of axle is connected with the output of drive unit by shaft coupling, it is characterized in that: toggle mechanism comprises Shifting rack and supporting leg, Shifting rack is fixedlyed connected by in the middle part of many supporting legs and the axle, and a plurality of strike rings are suspended on two ends and are fixed on the bearing pin in the Shifting rack hole.

Described annular crusher for massive materials, slideway between two stands I, base is near a side of material, width is greater than hitting annulate shaft to width, and curved being bent downwardly.

Described annular crusher for massive materials, an end has the bearing pin of socket cap, after being inserted by the outside in a Shifting rack hole, passes from the outside of another Shifting rack, and fixes by back-up ring I.

After described annular crusher for massive materials, cylindrical bearing pin inserted in the hole of two Shifting racks, two ends were fixed by back-up ring II respectively.

Described annular crusher for massive materials, an end have socket cap, the screwed bearing pin of the other end, after being inserted by the outside in a Shifting rack hole, pass from the outside of another Shifting rack, and fix by nut III and packing ring III.

Described annular crusher for massive materials, Shifting rack are annular, and circle diameter equates with the place circular diameter of each bearing pin.

Described annular crusher for massive materials, Shifting rack are polygon, and polygonal circumscribed circle diameter equates with the place circular diameter of each bearing pin.

Its operation principle is: the bottom of bracket I is fixed on above the base, the two ends of axle are installed in the bearing block by bearing, and bearing block is fixed on the bracket I top by bolt I, nut I and packing ring I, and the input of axle is connected with the output of drive unit by shaft coupling.When drive unit by after the shaft coupling driving shaft running because the supporting leg of toggle mechanism fixedlys connected with the axle middle part, and a plurality of strike ring is suspended on two ends and is fixed on the bearing pin Shifting rack hole in, so toggle mechanism will be stirred the strike threaded shaft by bearing pin and turn round.

In the strike ring is hoisted rotation process by lower, hit ring in the axle revolution, also do equidirectional rotation around bearing pin, therefore more and more higher with respect to the rotating speed of axle, see vertically, hit ring center, bearing pin center and 3 at center of axle and be tending towards straight line gradually.When peaking, strike ring center, bearing pin center and 3 at center of axle are in alignment basically, promptly hit ring and being thrown toward from the axle farthest.Rotate from high to low around axle along with hitting the ring continuation, hit ring center, bearing pin center and an axle center and become no longer in alignment gradually, hit the position of encircling with respect to bearing pin this moment and become in advance by hysteresis by sight alignment.

Promptly material is implemented to hit after hitting articulating to contact material, its rotating speed moment goes to zero.Because hitting ring is to hang on bearing pin, promptly hitting ring is not to be rigidly connected with toggle mechanism, hits the back and hits ring in the axle revolution, also will do reciprocal rotation around bearing pin, therefore can alleviate the anti-force of material to equipment itself greatly.Also Just because of this, this disintegrating machine has very strong adaptive capacity to the height of material striking point.In addition, be far longer than the bearing pin external diameter,, be unlikely to drop at once and hit ring although toggle mechanism is still remaining in operation when therefore hitting owing to hit the ring inner chamber.

Because the material surface is often smooth inadequately, therefore finish after the strike task, although limited the axial wobble of strike ring along axle because of the distance between two Shifting racks is slightly larger than the axial width that hits ring, it is uncertain to hit the high and low position that encircles.The present invention between two stands I, base is near a side of material, is provided with a width greater than hitting annulate shaft to width and be bent downwardly the slideway of camber, hits ring under the traction of bearing pin with guiding, change the plane and quicken gradually to rotate along hitting loopback.

The present invention is equipped with a plurality of self-alignment castors and supporting castor at base below by bolt IV, nut IV and packing ring IV, so that implement to hit along the periphery of super massive materials.

The present invention compared with prior art solved industries such as emery wheel, grinding tool and mine, building materials for the broken difficult problem of super massive materials, and proportion of powdery materials after crushing is low, and the blow efficiency height more helps alleviating working strength of workers.Simultaneously, limited well and hit the axial wobble of ring, improved the operational reliability and the practicality of this equipment greatly along axle.
