Description

A kind of hammer crusher

Technical field:

This utility model relates to a kind of hammer crusher.

Background technology:

Hammer mill mainly relies on percussion to crush building stones, and shattering process is, its building stones enter disintegrating machine In, it being subjected to the impact of the tup that high speed is turned round and crush, breaked building stones obtain kinetic energy at tup, rush at a high speed broken Counterpunch board in casing, meanwhile building stones mutually clash into, and are repeatedly crushed, less than the stone in broken casing discharging opening gap Material, discharges from discharging opening, the biggest building stones, again through the impact of tup in broken casing, extrudes and is broken, building stones Tup gap is extruded, thus is obtained the product of desired particle size.

Operationally, the impact force of counterpunch board is easily made broken casing produce shake to existing hammer mill by building stones Dynamic, long-term aggravation counterpunch board and the damage of broken casing in the past.

Rotor structure in existing hammer mill generally includes main shaft, end plate, hammer dish and tup, end plate, hammer dish with And by integrally welded structure between tup, after tup is lost, needing the whole rotor of integral replacing, replacement cost is high, and Waste of material is serious.

Therefore, necessary prior art improves to solve the deficiency of prior art.

Summary of the invention:

This utility model is in order to solve the problem of above-mentioned prior art existence and to provide a kind of hammer crusher.

The technical scheme that this utility model is used has: a kind of hammer crusher, including having the broken casing in rubble chamber, Also include that counterpunch board, pull bar, damping spring, clamp nut, draw-bar seat and rotor, three described draw-bar seats are fixedly connected on brokenly On the lateral wall of broken casing, three counterpunch boards are all hinged on the sidewall in broken casing rubble chamber, and pull bar one end is articulated with counterattack On plate, the other end passes on the sidewall of broken casing and is arranged on draw-bar seat, and clamp nut is threaded on pull bar, damping Spring housing is located on pull bar and one end is connected on broken casing, and the other end is connected on draw-bar seat, and rotor rotation is located at broken In casing；
