Description

High-strength hammer of crusher Technical Field The utility model relates to the technical field of crushers, in particular to a high-strength hammer of a crusher. Background The hammer head of the crusher is one of core parts of the hammer crusher, is arranged on a hammer shaft of a crusher rotor, directly strikes materials when the crusher runs at a high speed, is finally crushed into proper material granularity, and has the characteristics of good mechanical impact resistance, thermal shock resistance, wide application range, basically being applicable to all crushing industries and the like. At present, most of the existing crusher hammerheads are integrally designed, when the hammerheads are damaged, the whole hammerheads are required to be replaced, the replacement operation is complex, and the use cost is high due to the fact that the whole hammerheads are scrapped and replaced. Disclosure of utility model The utility model aims to provide a high-strength hammer head of a crusher, so as to solve the problems in the prior art. In order to achieve the purpose, the utility model provides the following technical scheme that the high-strength hammer head of the crusher comprises: The hammer comprises a hammer seat and a hammer head body, wherein a mounting groove is formed in the hammer seat, a plug seat is arranged on the bottom wall of the hammer seat, the plug seat is integrally formed with the hammer seat, two first plug grooves are formed in the bottom wall of the hammer seat, the two first plug grooves are symmetrically formed in two sides of the plug seat, a second plug groove is formed in the top wall of the hammer head body, the plug seat is movably plugged in the second plug groove, two connecting seats are arranged on the top wall of the hammer head body, the two connecting seats are symmetrically arranged on two sides of the second plug groove, the two connecting seats are integrally formed with the hammer head body, the connecting seats are movably plugged in the first plug grooves, two screw holes are formed in the connecting seats, two fastening bolts are plugged in the two side walls of the hammer seat through the formed through holes, and the fastening bolts are in the screw holes in a threaded mode. Preferably, the bottom wall of the hammer seat is fixedly welded with two rows of reinforcing connecting columns, the two rows of reinforcing connecting columns are symmetrically arranged on the front side and the rear side of the plug seat, and the top wall of the hammer head body is provided with two rows of jacks matched with the reinforcing connecting columns. Preferably, the hammer head body is made of hard alloy steel.
