Abstract
A breaker roll for waste asphalt mixture comprises a roll shaft and a roll body, wherein a plurality of groups of milling and planing assemblies distributed at equal intervals in the axial direction are arranged on the peripheral surface of the roll body; each group of milling and planing assembly consists of a plurality of milling and planing cutters distributed on a circumference and taking the roll body as the center; the milling and planing cutters of the milling and planing assemblies of two adjacent groups are alternatively arranged; wear-resistant lining plates are attached on the peripheral surface of the roll body between two adjacent milling and planing cutters; the breaker roll is coordinated with a jaw plate provided with a milling and planing groove; the milling and planing cutters on the breaker roll can alternatively stretch into the milling and planing groove, and are coordinated with the milling and planing groove to alternatively crunch the waste asphalt mixture, so as to effectively improve the crushing efficiency and the crushing effect.
Description
Technical field
The utility model relates to a kind of for the waste asphalt mixture breaker roll of (being called for short RAP:recycled asphalt pavement).
Background technology
Asphalt mixture heat regeneration technology be by old pavement material through digging or milling, fragmentation, screening utilize special equipment by its oven dry, heating, thawing with a certain proportion ofly newly gather materials, the material such as new pitch mixes and stirs again, formation has a whole set of technology of the regenerating mixture of certain pavement performance.In order to obtain high-quality reclaimed asphalt mixture, crushing and screening will be one of requisite technique of reworked material pretreatment.Owing to there being the existence of pitch in old material, in the time that temperature approaches asphalt solidification point, old material will harden and even lump.Result agglomerate diameter is greater than 50mm, after just cannot make waste asphalt mixture inside be heated to the temperature of needs in the technical process of heating, drying.Make the inside of old material still in sclerosis caking state because internal temperature is lower, like this can not be broken in the flow process of the caking of size after being heated.Such caking can not complete while making in other technical process below smoothly, affects mixture gradation, thereby has a strong impact on asphalt product quality.So excessive RAP needs to carry out fragmentation before heating.
Current, what generally adopt is that jaw crusher etc. carries out fragmentation, and these disintegrating machine operation principles are that the methods by pushing or knocking are carried out fragmentation.Bitumen recovery compound is by the pitch of viscosity, the building stones of all size to be bonded together, and pushes or knock for the viscosity effect of pitch limited, and the degree being therefore broken is low, cannot reach the technical requirement of grating.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of breaker roll coordinating with the jaw that is provided with milling groove is provided, milling cutter when work on breaker roll can alternately stretch in milling groove, coordinating with milling groove interlocks bites waste asphalt mixture into pieces, effectively improves crushing efficiency and crushing effect.
The purpose of this utility model realizes by following technical solution:
A kind of breaker roll for waste asphalt mixture, comprise roll shaft and roll body, it is characterized in that: described roll body outer peripheral face is provided with some groups of milling assemblies that axially equidistantly distribute along it, every group of milling assembly is made up of some milling cuttves of circle distribution centered by described roll body, the milling cutter interlaced arrangement of two adjacent groups milling assembly.
Further, the described roll body outer peripheral face between adjacent two milling cuttves is attached with abrasion-proof backing block.
Further, described abrasion-proof backing block is welded on described roll body outer peripheral face.
Further, described milling cutter is made up of the cutter that is fixedly installed on the tool rest on described roll body outer peripheral face and be removable installed on tool rest, described cutter is made up of knife bar and the cutter head that is arranged at knife bar end, and the relatively described roll body radial skew of described cutter is arranged.
Further, described tool rest is formed with the installation through hole that relatively described roll body radial skew extends, and described knife bar is removable installed in described installation through hole by expansion set.
Further, described cutter head is taper cutter head.
Further, described tool rest is welded on the outer peripheral face of described roll body.
The utlity model has following beneficial effect:
The breaker roll that the utility model provides is for coordinating with the jaw that is provided with milling groove, milling cutter when work on breaker roll can alternately stretch in milling groove, coordinate the staggered waste asphalt mixture of biting into pieces with milling groove, overcome the not breakable problem of viscosity because of pitch in RAP, effectively improve crushing efficiency and crushing effect; At the roll body outer peripheral face of breaker roll, some groups of milling assemblies are set, every group of milling assembly is made up of some milling cuttves, and the milling cutter interlaced arrangement of two adjacent groups milling assembly, every group of milling assembly coordinates with the corresponding groove of milling together, like this can be between guarantee milling cutter in effective clearance, improve the quantity of milling cutter, thereby improve crushing efficiency; Roll body outer peripheral face between adjacent two milling cuttves is attached with abrasion-proof backing block, can protect roll body to prevent roll body wearing and tearing, extends the service life of breaker roll; Milling cutter is made up of dismountable tool rest and cutter, can be convenient to replacing and the maintenance of cutter, reduces inspection and maintenance cost.
