A kind of permutation and combination method of the crushing teeth of breaker roll: the partial size of broken reclaimed asphalt mixture as needed, The size for judging the crushing teeth work department 221 needed, selects the crushing teeth 22 of the work department 221 of respective shapes.

When broken base's reclaimed asphalt mixture, breaker roll includes a plurality of types of tooth plates 2, the crushing teeth of each type 22 work department 221 is any three kinds in umbrella shape, taper, cylinder and hemispherical, and multiple 22 matrix arrangements of crushing teeth are the bottom of at On plate 21,221 shape of work department of the crushing teeth 22 of same file or row is identical.

Specifically, a kind of breaker roll of broken base's reclaimed asphalt mixture, including roll body 1 and tooth plate 2, tooth plate 2 include First tooth plate 24 and the second tooth plate 25, the leading portion of roll body 1 is arranged in the first tooth plate 24, after roll body 1 is arranged in the second tooth plate 25 Section, the work department 221 of the crushing teeth 22 of the first tooth plate 24 include umbrella shape, hemispherical and taper, the work department 221 of the second tooth plate 25 Including taper, hemispherical and cylinder, specifically, including that three intervals are uniformly arranged on breaking on bottom plate 21 on the first tooth plate 24 Broken tooth group, by work department 221, tapered respectively, hemispherical, the sequence of umbrella shape are arranged successively the crushing teeth 22 of three crushing teeth groups, It include that three intervals are uniformly arranged on crushing teeth group on bottom plate 21 on second tooth plate 25, the crushing teeth 22 of three crushing teeth groups presses work Make tapered portion 221, hemispherical, the sequence of cylinder are arranged successively.

When broken surface layer reclaimed asphalt mixture, breaker roll includes the tooth plate 2 of single type, the crushing teeth 22 of tooth plate 2 Work department 221 be polygon, cylinder and strip, multiple crushing teeths 22 are arranged in arrays on bottom plate 21, same file Or the shape of the work department 221 of the crushing teeth 22 of row is identical.

Specifically, a kind of breaker roll of broken surface layer reclaimed asphalt mixture, including roll body 1 and tooth plate 2, wrapped on tooth plate 2 It includes three and is spaced the crushing teeth group being uniformly arranged on bottom plate 21, three crushing teeth groups are arc-shaped by work department 221, are polygon Shape, the sequence of strip are sequentially arranged on bottom plate 21.

By the way that dismountable crushing teeth 22 is arranged on tooth plate 2, crushing teeth 22 can select work department according to actual needs 221 suitable crushing teeths 22, to reach broken demand, when broken base's reclaimed asphalt mixture, because of base's regeneration asphalt The partial size of mixture is generally larger, in the case where not destroying original gradation, it is desirable to which the work department 221 of crushing teeth 22 is small, institute It is umbrella shape with selection work portion 221, taper, cylinder, hemispheric crushing teeth 22, the accommodating chamber between such crushing teeth 22 is just It can accordingly increase, when being crushed, a possibility that being caught broken raw material gradation is substantially reduced, to obtain good crushing effect, works as the plane of disruption When layer reclaimed asphalt mixture, because the gradation partial size of surface layer reclaimed asphalt mixture is small, and contains tiny powdery particle, drip Green content is more, requires the work department 221 of crushing teeth big when being crushed, so selecting polygon, arc-shaped, strip broken Tooth, the accommodating chamber between such crushing teeth 22 will accordingly become smaller, when being crushed, can as far as possible to reclaimed asphalt mixture mutually into Row rubbing, tearing separation, when being crushed surface layer reclaimed asphalt mixture, the crushing teeth 22, Neng Gouwen that needs to select work department 221 big With it is broken, RAP will not be caught broken, to reduce dust, avoid dust pollution.

The above, the only preferred embodiment of the utility model, therefore the utility model implementation cannot be limited with this Range should still belong to this that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description In the range of utility model patent is covered.
