Description
Technical field
This utility model relates to asphalt mixing plant technical field, more specifically refers to a kind of for reclaiming waste and old drip
The breaker roll of blue or green compound.
Background technology
Asphalt mixture heat regeneration technology is through digging or milling, broken, screening utilize special setting by old pavement material
Standby be baked to, heat, melt and a certain proportion of newly gather materials, the material such as new Colophonium mixes and stirs again, and formation has certain road use
The whole set process technology of the regenerating mixture of performance.In order to obtain high-quality reclaimed asphalt mixture, crushing and screening will be again
One of requisite technique of raw material pretreatment.Owing to old material having the existence of Colophonium, when temperature is close to asphalt solidification point, old
Material will harden and even lump.Result agglomerate diameter is more than 50mm, just cannot make back later in the technical process of heating, drying
Receive the temperature being heated to needing inside asphalt pavement material.Make the inside of old material be still within hardening owing to internal temperature is relatively low
Caking state, this level of caking can not crush in the flow process after being heated.Such caking makes follow-up work
Skill process can not smoothly complete, and affects mixture gradation, thus has a strong impact on asphalt product quality.Therefore, excessive
RAP is required for carrying out crushing and screening before heating.
Traditional method is that excessive RAP is crushed by jaw crusher etc., and these disintegrating machine operation principles are to pass through
Extruding or the methods tapped crush.Bitumen recovery compound is by bonding for the building stones of all size by the Colophonium of viscosity
Together, extruding or tap the viscosity limited use for Colophonium, the degree being therefore broken is low, it is impossible to reach the technology of grating
Requirement.For overcoming disadvantage mentioned above, Authorization Notice No. is that the Chinese utility model patent of CN202700589U discloses a kind of Colophonium
Reclaim the disintegrating apparatus of compound, including old feed bin warehouse, breaker drum, shaft coupling, reductor, hydraulic means, hydraulic jack, give
Flitch, wherein, breaker drum includes rotary shaft and broken blade, and described broken blade is the most equal along the circumferencial direction of rotary shaft
Cloth.Although this breaker drum can improve broken work efficiency, but rotating shaft is exposed outside easily by RAP impact wear, and it uses the longevity
Order short, need often to shut down replacing, have impact on the operational efficiency of disintegrating apparatus.
Utility model content
This utility model provides a kind of breaker roll for reclaiming waste asphalt mixture, and its main purpose is to overcome now
There is the rotating shaft of breaker roll by RAP impact wear, the shortcomings such as service life is short.
This utility model adopts the following technical scheme that
A kind of breaker roll for reclaiming waste asphalt mixture, including rotating shaft, abrasion-proof backing block, milling tool rest and milling
Cutter, described abrasion-proof backing block is detachably secured on shaft circumference face, the most equal along rotating shaft of described abrasion-proof backing block
Curl arranges, and two abrasion-proof backing block junctions adjacent on same circular radial side face are at least provided with a resigning hole, Mei Gerang
Position is fixed with a milling tool rest at hole, and described milling tool rest is along the most all curl arrangements, each milling of rotating shaft
One milling cutter is installed on adz block.
Further, above-mentioned milling tool rest is provided with an installing hole, and the cutter shaft of above-mentioned milling cutter is inserted into this installing hole,
And milling cutter exposes the cutter spindle sleeve outside installing hole equipped with a wear-resistance protective sleeve and a check washer.
Further, the tangent line at each milling cutter abrasion-proof backing block place corresponding to it on above-mentioned same circular radial side face
Direction angulation is identical.
Further, the same hand of spiral that above-mentioned rotating shaft is axial staggers between adjacent two milling tool rests equal angular
Arrange, and on same circular radial side face, adjacent two milling tool rests same distance that staggers is welded on the periphery of described rotating shaft.
Further, on above-mentioned rotating shaft same circular radial side face, equal distribution has six milling tool rests, same radial circumference
On face, adjacent two milling tool rests 15mm that staggers is welded on rotating shaft outer surface, adjacent two milling cuttves on same axial screw direction
Stagger between Zuo 6 ° and arrange.
Preferably, above-mentioned abrasion-proof backing block uses rich chromium cast iron abrasion-proof backing block.
From the above-mentioned description to this utility model structure, compared to the prior art, this utility model has the most excellent
Point: this breaker roll is replaceable along the surface of rotating shaft is provided with the abrasion-proof backing block in axially and radially all curl arrangements, same footpath
Two abrasion-proof backing block junctions adjacent on periphery are provided with the resigning hole for installing milling tool rest, and milling tool rest is along rotating shaft
The most all curl arrangements, therefore the breaker roll of this structure can protect rotating shaft and milling tool rest not to be subject to effectively
RAP material impact weares and teares, and improves rotating shaft and the service life of milling tool rest, is not dismantling milling cutter and milling tool rest simultaneously
In the case of can quickly abrasion-proof backing block be replaced, improve breaker roll maintenance efficiency.It addition, milling tool rest uses radially and axle
Mode to equal spiral is arranged, and RAP material can be carried out any angle and crush, prevent sky and dig phenomenon, improve broken
Efficiency.
