Abstract
The invention discloses a crushing device of a coal crusher. The crushing device comprises an upper shell and a lower shell, wherein an active drive wheel disc and a passive drive wheel disc are arranged on the upper shell and are respectively connected with a crushing roller, the crushing roller comprises a cylindrical roller main body, a drive pivot is arranged at the center of the roller main body, and a gear hob array consisting of gear hobs is arranged on the outer wall of the roller main body. A pair of crushing rollers is used for replacing the existing blades, and because the inverted trapezoidal gear hobs are arranged on the outer surface of the crushing roller, the crushing device of the coal crusher is capable of fully crushing coal, and also preventing relative slipping of the crushing roller. Moreover, the crushing roller is made of cast iron integrally, and has the advantages of high strength and low cost.
Description
Technical Field
The invention relates to coal mining equipment, in particular to a crushing device of a coal crusher.
Background
The coal crusher is also called a double-stage crusher, belongs to high-efficiency fine crushing equipment and mainly aims at the crushing problem of coal with high moisture content. The crushing cavity of the existing coal crusher mostly adopts a blade type crushing mode, blades need to be replaced regularly, and the use cost is high.
Disclosure of Invention
The invention mainly solves the technical problems in the prior art, and provides a crushing device of a coal crusher.
The technical problem of the invention is mainly solved by the following technical scheme:
the crushing device of the coal crusher comprises an upper casing and a lower casing, wherein an active driving wheel disc and a passive driving wheel disc are arranged on the upper casing, the active driving wheel disc and the passive driving wheel disc are respectively connected with a crushing roller, the crushing roller comprises a cylindrical roller main body, a driving pivot is arranged at the center of the roller main body, and a hobbing array consisting of hobbing is arranged on the outer side wall of the roller main body.
As a preferred embodiment of the invention, the hobbing is in an inverted trapezoid shape.
