Description

Impact breaker

Technical field

The utility model belongs to mining machinery technical field, and in particular to a kind of impact breaker, for mineral matter Raw material such as lime stone, coal etc. are broken.

Background technology

Impact breaker is a kind of to be implemented the raw mineral materials to enbrittle lime stone as the aforementioned using impact principle Broken crushing mechanism, its disintegrating machine with squash type principle（Such as jaw, rotary, circular cone type, roll-type）Compare, due to broken Than big, thus production system can be simplified and reduced investment outlay.Rotor is the power core of impact breaker（Bar, which is arranged on, to be turned On son）, the whether reasonable operating efficiency to disintegrating machine of its structure and the crushing effect to raw mineral materials can produce important shadow Ring.

Technical information on the rotor of impact breaker can be largely seen in disclosed Chinese patent literature, such as be awarded Weigh notification number CN2704415Y（The rotor of beating type crusher）、CN2899936Y（The full combined type of impact breaker turns Son）、CN201470430U（Impact crusher rotor）、CN201394473Y（Reaction-type crusher rotor device）、 CN201659001U（The rotor arrangement of impact breaker）, publication No. CN102179275A（Polygonal welded-type impact is broken to be turned Son）、CN202037029U（The rotor of impact crusher）、CN202137010U（Novel rotor of impact crusher）、 CN202087355U（The attachment structure of impact crusher rotor plate and bar）、CN202137010U（New backpulsing disintegrating machine Rotor）、CN202516617U（It is a kind of to strike back broken rotor structure）, publication number CN1634660A（Impact crusher rotor）With Publication No. CN102179276A（Impact crushing rotor）, etc..

The rotor structure of patents and patent applicationss scheme exemplified above is not limited to generally in the structure shown in Fig. 4 Make, including rotor main shaft 1 and one group of hammer disk 2 being arranged on space state on rotor main shaft 1, with weldering on one group of hammer disk 2 The mode of connecing is fixed with bar seat 21.Theoretically, bar seat 21 is reliable by welding the effect being combined as a whole with hammer disk 2 , but in the case where impact breaker is in running order, the great force from bar easily make bar seat 21 and hammer disk 2 it Between welding position destroyed, cause bar seat 21 is overall to come off, influence impact breaker if being repaired in time on it Operating efficiency, and rehabilitation cost is larger, if repaired not in time to it, then the anxiety that machine is ruined in initiation be present, if changed New impact breaker, then not only cause investment to increase, and cause the wasting of resources.Therefore tediously long bar seat 21 is made Queried for an independent part and one group of welded structure form of hammer disk 2 by industry, and it is expected to improve.

" rotor structure of impact breaker " that invention patent mandate notification number CN103831150B is provided is due to by plate Hammer seat directly constitute in hammer disk and two it is adjacent hammer disks between and in the position corresponding to bar seat, there is provided the increasing of bar seat Strong block, thus when impact breaker is in running order, bar seat will not damage because of the great force of bar, not only may be used To ensure the lasting operating efficiency of impact breaker, and maintenance cost can be saved significantly on and avoid the wasting of resources（Say The 0017th section of bright book）.

But still there is following 2 shortcoming in above-mentioned CN103831150B：First, due to for one piece of bar, Need to be equipped with a fairly large number of one group of hammer disk enhancing block, specifically directly constitute in each two adjacent hammer disk seats on hammer disk it Between be respectively bumped into a hammer disk enhancing block, the otherwise bar seat easily fragmentation under the impulsive force of bar, thus exist attend to one thing and lose sight of another ask Topic, it is so-called care for this, be as able to promote bar seat generally robust effect, it is so-called lose that be cause to manufacture and fiber crops be installed It is tired, such as the bar seat pin axis hole that supply and marketing axle is worn not only is opened up on bar seat, and phase on block need to be strengthened in each hammer disk Pin shaft hole should be opened up, the pin shaft hole is corresponding with foregoing bar seat pin axis hole, to be interted by bearing pin；Second, due to except Foregoing one group directly constitutes outside need to also be by contract block plate and contract block in the bar seat on hammer disk and one group of hammer disk enhancing block Collaboration and so that bar limits, thus structure is relative complex, same to be made troubles to manufacture with installation.

For above-mentioned prior art, still there is improved necessity, the applicant has made beneficial design for this, forms following The technical scheme that will be introduced, and simulate deduction experiment through computer in the case where taking secrecy provision and be proved to be practical 's.
