Abstract

A detachable composite hammer head belongs to the technical field of machinery and is characterized by being provided with two hammer head connection bodies which are connected in involution mode to form a hammer head body and an abrasion-resistant block. The abrasion-resistant block is fixedly installed at the front end of the hammer head body in clamping mode by the hammer head connection bodies, a boss or a groove is respectively arranged at the contact positions of the hammer head connection bodies and the abrasion-resistant block, the boss and the groove are connected in matching and clamping mode, a bolt connection fixed hole is arranged on the front portion of the hammer head body, and an insertion hole and a pin roll connection fixed hole which are connected with a hammer handle in installation are arranged on the back portion of the hammer head body. The detachable composite hammer head is long in service life, low in cost and simple and reasonable in structure, improves economical benefit, saves production cost, can be detached in use and has wide market prospect.

Description

technical field [0001] The invention relates to a hammer head of a crusher, in particular to a detachable and replaceable composite hammer head on a crusher, and belongs to the field of mechanical technology. Background technique [0002] The hammer head of the crusher is the hammer head of the hammer crusher. The hammer head is one of the core components of the hammer crusher. It is arranged on the hammer handle of the rotor of the crusher. into a suitable material particle size. During the working process of the crusher, the hammer head is the most easily worn part. The reason is that the impact and friction of the material cause the loss of the hammer head. Production has a decisive influence. In recent years, with the rapid development of the coking industry, the coal resources used for tamping coking coal are in short supply, the proportion of coking coal has changed greatly, and a large amount of low-quality hard coal has been mixed in for coking, which directly lead...
