Abstract
The utility model proposes a kind of cutterhead shape crushing teeth for rod-toothed crusher, comprise crushing teeth and dish body, be made up of monoblock steel plate, crushing teeth is distributed in dish body periphery, and dish body is provided with circular mounting hole.Crushing teeth is directly cut into by mach mode on dish body.Crushing teeth is to lopsidedness, and tine angle is 15 °～45 °.Crushing teeth has crest top land, and crest top land length is 15～30mm.The tooth rear profile of crushing teeth is cambered surface, and cambered surface radius is 40～100mm.The junction of crushing teeth and tooth body is fillet, and fillet is of a size of 10～30mm.Compared with prior art, the utility model has the advantage of, adopt the mode that directly cuts out crushing teeth on monoblock steel plate, can guarantee that crushing teeth is uniformly distributed, not frangibility, can not fall tooth phenomenon.Crushing teeth, to lopsidedness, can ensure that crushing teeth has good crushing efficiency.
Description
Technical field
The utility model relates to a kind of cutterhead shape crushing teeth, relates in particular to a kind of cutterhead shape crushing teeth for rod-toothed crusher.
Background technology
At present rod-toothed crusher crushing teeth used, adopts the crushing teeth of casting mostly, also has the deformed steel flats of employing as crushing teeth, by bolt or be welded on breaker roll.These type crushing teeths are difficult for being uniformly distributed, and easily broken teeth occur, fall tooth phenomenon.
Summary of the invention
The purpose of this utility model is the weak point existing in above-mentioned background technology in order to solve, and a kind of cutterhead shape crushing teeth for rod-toothed crusher is provided.
According to the cutterhead shape crushing teeth for rod-toothed crusher the utility model proposes, comprise crushing teeth and dish body, to be made by monoblock steel plate, crushing teeth is distributed in dish body periphery, and dish body is provided with circular mounting hole.Crushing teeth is directly cut into by mach mode on dish body.Crushing teeth is to lopsidedness, and tine angle is 15 °～45 °.Crushing teeth has crest top land, and crest top land length is 15～30mm.The tooth rear profile of crushing teeth is cambered surface, and cambered surface radius is 40～100mm.The junction of crushing teeth and tooth body is fillet, and fillet is of a size of 10～30mm.
Compared with prior art, the utility model has the advantage of, adopt the mode that directly cuts out crushing teeth on monoblock steel plate, can guarantee that crushing teeth is uniformly distributed, not frangibility, can not fall tooth phenomenon.Crushing teeth, to lopsidedness, can ensure that crushing teeth has good crushing efficiency.
