Description

A kind of symmetrical double-cavity jaw crusher
Technical field
The present invention relates to a kind of particle technology, more particularly to a kind of symmetrical double-cavity jaw crusher.
Background technology
Jaw crusher is mainly used in crushing various low middling hardness materials, because its reduction ratio is big, product grain Uniform, simple structure, dependable performance, the low advantage of easy to maintenance, running cost are spent, is widely used in metallurgy, chemical industry, ore deposit The industry-by-industries such as mountain, cement.
Current jaw crusher simulates two jaw movements of animal, and it drives dynamic jaw to swing by motor so that dynamic jaw group It is mutually twisted with jaw is determined, realization is crushed to material.In dynamic jaw group swing process, adjusting mechanism for discharging hole is used for branch racking jaw Group simultaneously adjusts dynamic jaw group and determines the discharging opening size between jaw frame, and dynamic jaw tenses buffer gear to be used to tense dynamic jaw group and have buffering Effect.
The jaw frame of determining of jaw crusher includes determining gnathosoma, being fixed on and determine to determine jaw liner plate on gnathosoma, determines jaw liner plate and rigidly connects It is connected on and determines on gnathosoma.In broken building stones, determine jaw and dynamic jaw is squeezed and can produce sharp pounding, rigidly connected structure can be by Vibrations are transferred in whole frame, so as to cause equipment seismaesthesia strong, influence safety in production;Also there is broken effect in single-chamber disintegrating machine Rate is low, the flywheel of heaviness is needed in structure, the shortcomings of charging aperture cannot be adjusted.
The content of the invention
In view of this, it is a primary object of the present invention to provide a kind of efficiency high, easy for installation, low cost symmetrical two-chamber Jaw crusher.
In order to achieve the above object, technical scheme proposed by the present invention is:
A kind of symmetrical double-cavity jaw crusher, including:Two single-chamber jaw crushing mechanisms for being used for comminuting matter, for leading to The transmission mechanism that external impetus drive two single-chamber jaw crushing mechanisms to work simultaneously is crossed, for being two single-chamber jaw crushers Structure provides support, adjustment two single-chamber jaw crushing mechanism motion amplitudes, exterior contours with transmission mechanismThe machine of type Frame;Wherein, two single-chamber jaw crushing mechanisms are symmetrical with frame by transmission mechanism;The second elbow is additionally provided with frame Groove;
Single-chamber jaw crushing mechanism includes:Constitute crusher chamber determines jaw and dynamic jaw, adjusts crusher chamber discharging opening size and two The round and smooth bracket in end;Determine jaw to be fixed with frame side wall;Dynamic jaw one end is rotatably coupled with transmission mechanism, is set at the dynamic jaw other end It is equipped with the first elbow groove;Bracket one end is installed in rotation in the second elbow groove, and the bracket other end is installed in rotation on the first elbow In groove;The dynamic jaw other end is rotatably coupled with bracket one end, and the dynamic jaw other end is also movably coupled to frame.
In sum, symmetrical double-cavity jaw crusher of the present invention is in crushing hard material, and transmission mechanism is by outside Power is transmitted to dynamic jaw, is moved jaw and is swung broken and outputting material by complicated;In the present invention, two symmetrical single-chamber jaw crushings Machine works simultaneously in the case of external impetus are not enhanced:When a single-chamber jaw crusher carries out material to be crushed, another Material after the output of single-chamber jaw crusher is broken.As can be seen here, symmetrical double-cavity jaw crusher of the present invention does not have backlash Stroke, this allows for its operating efficiency and obtains larger raising;Heavy flywheel is not needed, mechanism is simplified, is alleviated and is set Standby weight;Gear drive can realize the amplification slowed down with power, can reduce the gearratio of upper level transmission.Simultaneously as Two single-chamber jaw crushers are symmetrical, and many parts are identical, and just with processing, therefore symmetrical double-cavity jaw crusher of the present invention holds Easy processing, installation, adjustment, and simple structure, cost are relatively low.
