Abstract
The utility model discloses a roller toothed plate of a crusher, which comprises the roller toothed plate of the crusher; bolt holes on the roller toothed plate are respectively arranged at the corresponding positions of two high teeth between two circular tooth rings; and the upper ends of the bolts holes are respectively extended with a section of hole protecting platforms with the height being the same as that of a lower tooth. The roller toothed plate uses the hole protecting platforms to protect bolts, thus effectively avoiding the bolts being worn by material when in work, and having the advantages of reliable work, convenient maintenance, and prolonging the service life of the toothed plate.
Description
Technical field:
The utility model relates to fragmentation, particularly a kind of install and fix hidden, bolt not easy to wear, stable and reliable operation disintegrating machine roller tooth plate.
Background technology:
Fixing of existing disintegrating machine roller tooth plate and roller, be to be fixed on the roller through the screw on the roller with bolt, the defective that this traditional fixed form exists is the exposure formula on tooth plate because of screw, the bolting occiput exposes and contacts with material, easily cause wearing and tearing and loosening, bring influence to maintenance, also greatly reduce the service life of tooth plate.
Summary of the invention:
The purpose of this utility model provide a kind of bolt install hidden, be difficult for causing the bolt wearing and tearing and become flexible, maintain easily, the disintegrating machine roller tooth plate of long service life.
The technical solution of the utility model is finished as follows, it includes a disintegrating machine roller tooth plate, it is characterized in that: the bolt hole on the Cylindrical toothed plates is located at two high tooth corresponding positions between the two circle ring gears respectively, and each bolt hole upper end prolongs respectively one section guard aperture platform identical with low tooth height.The tapered body of the shape of each guard aperture platform.The utility model is protected bolt with the guard aperture platform, and material weares and teares bolt when having avoided work effectively, have reliable operation, easy to maintenance, improve the tooth plate advantage in service life.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is improvements over the prior art, and as shown in drawings, it is the corresponding position that the bolt hole on the Cylindrical toothed plates 15 is located at two the high teeth 2 in centre of two circle ring gears respectively, and each bolt hole upper end prolongs respectively one section guard aperture platform 3 highly identical with low tooth 4.The shape of each guard aperture platform is conical or square taper.During installation, hidden in the guard aperture platform after the bolted, during work, the material bolt that can directly not wear and tear has been avoided the quick wearing and tearing of bolt effectively, has reduced and has safeguarded trouble and the cost of changing tooth plate, has prolonged the service life of tooth plate.
