Description

A kind of impact breaker

Technical field:

This utility model relates to a kind of impact breaker.

Background technology:

Impact breaker mainly relies on percussion to crush building stones, and shattering process is, its building stones enter broken In machine, 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 brokenly at a high speed Counterpunch board in broken 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 impact breaker by building stones Dynamic, long-term aggravation counterpunch board and the damage of broken casing in the past.

Rotor structure in existing impact breaker generally includes main shaft, end plate, hammer dish and tup, end plate, hammer dish And by integrally welded structure between tup, after tup is lost, need 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 impact breaker.

The technical scheme that this utility model is used has: a kind of impact breaker, including the broken case with rubble chamber Body, also includes counterpunch board, pull bar, damping spring, clamp nut, draw-bar seat and rotor, three fixing connections of described draw-bar seat 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 On counterpunch board, 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 is sheathed on pull bar and one end is connected on broken casing, and the other end is connected on draw-bar seat, and rotor rotates and is located at In broken casing；

Described rotor includes rotating shaft, connecting tube, hammer dish, end plate and bar, and described connecting tube is connected in rotating shaft, two ends Dish is fixed on the two ends of connecting tube, some hammer dishes being fixed in connecting tube and between two end plates the most across a certain distance, plate Hammer the axial direction along rotating shaft into shape to be connected on described end plate and hammer dish.

Further, described end plate is provided with the first slot, and hammer dish is provided with second connected with described first slot Slot, bar is connected on end plate and hammer dish by first and second slot.

Further, the sidewall of described second slot is provided with positioning boss, and bar sidewall is provided with and described convex The detent that platform is suitable.

Further, on described end plate sidewall and be positioned at the first slot-side and be provided with latch segment.

Further, described counterpunch board includes that connecting plate and liner plate, described liner plate are fixed on connecting plate.

Further, described liner plate is provided with ratchet and square opening.

This utility model has the advantages that

(1) damping spring in this utility model is during rubble, it is possible to effectively slow down building stones by counterpunch board Act on the impulsive force of broken casing, thus reduce the vibrations of broken casing；

(2) it is demountable structure between the bar in this utility model rotor and hammer dish, after bar is lost with tup, Directly change these loss parts and without integral replacing rotor, replacement cost is low, save material.
