Description
Technical field
The present invention relates to a kind of waste asphalt mixture breaker roll, more particularly to it is a kind of have improve truss plate connection structure
Waste asphalt mixture breaker roll.
Background technology
One important link of recycling waste asphalt mixture (RAP) is by old asphalt pavement by milling, broken formation
Chunky shape material, this chunky shape material is to bond pockets of " combination " by former road surface mineral aggregate and Bituminous concrete surface, not single
Gather materials.The difference of the old asphalt mixture of separate sources is also very big, different gradings, different milling thickness, different milling machines
The influence of many factors such as tool causes the conglomeration situation of old mixture to there is very big difference.Therefore, to bituminous paving milling material
(RAP) pretreatment is a very important program, it is mainly to aniseed in sample (generally higher than 40mm), " uniting to expect "
Processing because it is excessive, caking old mixture when heated, since the thermal conductivity of pitch is poor, a large amount of energy can be wasted.
Be presently used for old asphalt mixture (RAP) disclosure of broken recycling has part using the broken of pair roller type
Machine etc. is crushed, and basic functional principle is the breaker roll tooth plate and floating type broken roll structure by interlaced arrangement, can
The RAP of big specification is rubbed, is squeezed, tears alternating action, destroys pitch bonding effect in RAP, while aggregate can enter
, will not be broken by rolling in concavity chamber, and then prevent the original gradings of RAP from being destroyed.
But in view of the above technology, at present breaker roll tooth plate fixed form be using the fixed mode of dormant bolt,
Although dormant bolt is designed using counterbore closely-pitched, the locking measures such as anaerobic adhesive are smeared, find that this structure still can in practical application
It bolt looseness or is directly loosened caused by body shakes, causes tooth plate to fall off, tooth plate, which once falls off, may cause safety accident.
In addition, even if bolt does not loosen, because being in the working region of roll surface at the top of bolt, it also will appear the continuous abrasion spiral shell expected by RAP
At the top of bolt, lead to damage at the top of bolt, when later stage fracturing service replaces tooth plate, bolt is not easy to remove, gives plant maintenance spare part
Replacement brings inconvenience.
Invention content
To overcome deficiency in the prior art, a kind of truss plate connection of present invention offer is reliable, anti-shearing force is big, easily replaces and tears open
That unloads has the waste asphalt mixture breaker roll for improving truss plate connection structure.
To achieve the above object, the technical solution adopted by the present invention is as follows：It is a kind of that there is the useless of improvement truss plate connection structure
Old asphalt mixture breaker roll, including roll body, several tooth plates for being arranged on roll body, it is characterised in that：It is formed on the roll body
Have connecting groove, be provided on the surface that the tooth plate is contacted with the roll body protrusion rail portion, the rail portion with it is described
Connecting groove complements each other to form interconnecting piece.
Further, the connecting groove on roll body is axially extending along the roll body, and the connecting groove is at least
One end open is in the roll body end.
Further, further include roll surface baffle ring, the roll surface baffle ring is fixed at the roll body end being open with connecting groove
Portion, roll surface baffle ring limit the opposite sliding between tooth plate and roll body in axial direction.
Further, multiple connecting grooves are distributed on described its peripheral surface of roll body upper edge, the tooth plate passes through
Its rail portion is connected to the connecting groove on the roll body.
Further, there is hollow portion in roll body.
Further, each tooth plate is provided with several rail portions.
Further, rail portion includes root and limiting section, and limiting section is cut by root and truss plate connection, the limiting section
Face maximum width is more than root section maximum width.
Further, limiting section cross sectional shape is round, trapezoidal, oval, rectangle, one kind in hexagon or more
Kind, there is cross sectional shape corresponding with limiting section with the matched connecting groove of rail portion.
By the above-mentioned description of this invention it is found that compared with prior art, it is provided by the invention have improve truss plate connection
The waste asphalt mixture breaker roll of structure, roll body are attached with tooth plate using the interconnecting piece that guide rail coordinates with connecting groove,
Compared to the mode that is bolted, interconnecting piece is caused to be destroyed when connection type of the invention will not work because of tooth plate, and
And guide rail connect with connecting groove after forced section bigger between the two, the anti-shearing force with bigger, tooth plate is not easily to fall off, and connection can
By property height；Rail type design is easier to dismounting when tooth plate is replaced, convenient for safeguarding；Guide rail selects suitable tolerance with connecting groove
Cooperation, tooth plate work when with roll body do not generate radial displacement, tooth plate is limited by roll surface baffle ring, tooth plate work when and roller
Body does not generate axial displacement, and it is more reliable to be crushed roll structure for tooth plate longer life expectancy.
