Description
Technical Field
The utility model relates to a part of breaker, concretely relates to components of a whole that can function independently hard rock counterattack formula breaker bar.
Background
The plate hammer is a main part of a hard rock impact crusher for striking stone materials, belongs to a wearing part, and is made of high-strength steel. Typically, four sets of eight plate hammers are provided for the rotor of a single impact crusher. Due to the bad working condition, the plate hammer is worn quickly, and the plate hammer needs to be replaced when being worn to a certain degree. Because each plate hammer is cast into a whole, the plate hammer needs to be replaced integrally during replacement, and the cost is higher.
Disclosure of Invention
In order to solve the problem, the utility model provides a components of a whole that can function independently hard rock impact crusher bar.
The utility model adopts the technical proposal that:
the split hard rock impact crusher plate hammer mainly comprises a plate hammer head, a plate hammer body and a puller bolt; the plate hammer head is a long rod body with one side provided with an arc shape and the other side provided with a protruding dovetail part; the plate hammer body is also a long rod body, two dovetail grooves are symmetrically arranged on two sides of the plate hammer body respectively, two bolt holes are arranged at two ends of the plate hammer body respectively, and an installation lug I and an installation lug II are arranged on the other two sides of the plate hammer body; and the dovetail part and the dovetail groove are utilized to respectively install the two plate hammer heads on the plate hammer body, and the jacking bolt is screwed into the bolt hole to fix the plate hammer head on the plate hammer body.
The beneficial effects of the utility model are that: the plate hammer is manufactured in a split mode, the two plate hammers and the plate hammer body form the plate hammer, the plate hammers and the plate hammer body are connected with dovetail grooves through dovetail portions, the plate hammer body is made of cast steel instead of steel, precision machining can be achieved, bolt holes are formed in the plate hammer body, the plate hammers are tightly pressed through bolts, assembly gaps of the dovetail portions can be eliminated, and the plate hammer has the advantages of being low in manufacturing cost, high in precision, beneficial to replacement and the like.
