Abstract
The invention provides a throwing head device of an impact crusher. The throwing head device comprises a throwing head base, an outer throwing head and an inner throwing head. The outer throwing head and the throwing head base are connected in a concave-convex plugging mode, and the inner throwing head and the throwing head base are connected in a concave-convex plugging mode. The end face of the outer throwing head and the end face of the inner throwing head are each provided with counter bores or through holes. Fastening bolts are arranged in the corresponding positions of two discs of a rotor for fixation. On the one hand, the strong impact force resistance capacity of the throwing heads is improved, and the phenomenon that connecting heads between the throwing heads and the throwing head base are broken is avoided; and on the other hand, the phenomenon that fastening bolts in traditional schemes are loosened and abraded and fall off due to material impact is effectively avoided. Replacement of the throwing heads is easier and more convenient and feasible, and the operation cost of equipment is lowered. Further, the invention provides the impact crusher.
Description
Technical field
The invention belongs to field of cracking machine, be specifically related to thrower head device and the punching of a kind of impact crusher
Impact crusher.
Background technology
