Abstract
The utility model belongs to the technical field of crushers, particularly relates to a crusher rotor, and solves the technical problem that the conventional technology is not reasonable. The crusher rotor comprises a rotating shaft, wherein a hammer disc mechanism is arranged on the rotating shaft; end discs are respectively arranged at two ends of the hammer disc mechanism; belt pulleys are fixedly connected with the rotating shaft. The crusher rotor is characterized in that at least two pull rods capable of fixing the end discs on the hammer disc mechanism are arranged on the hammer disc mechanism; a rotating shaft hole for mounting the rotating shaft is formed in the center of the hammer disc mechanism; the pull rods are uniformly distributed on the hammer disc mechanism by taking the center of the rotating shaft hole as the center of circle. Compared with the prior art, the crusher rotor has the advantages that the design is reasonable, the structure is simple, the mounting is firm, the structural strength is high, the service life is long, the working is stable, the working stability of a crusher is improved, and potential safety hazard is reduced.
Description
Technical field
The utility model belongs to disintegrating machine technical field, especially relates to a kind of crusher rotor.
Background technology
Disintegrating machine mainly carries out crushing operation to all kinds of building stones, according to broken principle difference and product particle, varies in size, and is divided into again a lot of models.Disintegrating machine is widely used in numerous departments such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.Conventional crushing mechanism has jaw crusher, impact breaker, impacting vertical crusher, hydro cone-crusher, ring hammer crusher, hammer mill, kibbler roll, compound crusher, cone crusher, twin-stage disintegrating machine, gyratory crusher, movable crusher etc.Crusher rotor is one of main part of disintegrating machine.
For example, Chinese patent literature discloses a kind of rotor for disintegrating machine [application number: CN201120536530.X], comprise rotor wheel, back-up ring, rotor hub and rotor wheel catch, rotor wheel is welded on rotor hub, back-up ring is welded on the outside at rotor wheel sheet hammer axis hole two ends, the thickness of rotor wheel sheet is 72mm, and the cylindrical otic placode place arc chord angle of rotor wheel sheet is R100.
Although such scheme can be used for disintegrating machine, still exist in crushing operation, this part is installed the technical problems such as firm not, and this not only can affect the service behaviour of disintegrating machine and the service life of other parts, more can have security hidden trouble.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, and firmly crusher rotor is installed.
For achieving the above object, the utility model has adopted following technical proposal: this crusher rotor, comprise rotating shaft, described rotating shaft is provided with hammer disc mechanism, at hammer disc mechanism two ends, be respectively equipped with end plate, in described rotating shaft, be fixed with belt pulley, it is characterized in that, described hammer disc mechanism is provided with at least two pull bars that end plate can be fixed on hammer disc mechanism, the center of described hammer disc mechanism is provided with the shaft hole that rotating shaft is installed, and described pull bar be take shaft hole center and is distributed on hammer disc mechanism as center of circle even circumferential.
In above-mentioned crusher rotor, described pull bar is located on hammer disc mechanism, and described end plate is provided with tie rod hole, and described pull bar is arranged on tie rod hole, and described pull bar is provided with the nut that end plate can be fixed on hammer disc mechanism.
In above-mentioned crusher rotor, described hammer disc mechanism comprises several hammer dishes, is equipped with the hammer axle that some even circumferentials distribute on hammer dish, and described hammer axle is provided with the tup between adjacent two hammer dishes.
In above-mentioned crusher rotor, described pull bar is arranged between adjacent two hammer axles.
In above-mentioned crusher rotor, in the rotating shaft at described hammer disc mechanism two ends, be respectively equipped with bearing block.
