Description

Single toggle jaw crusher

Technical field

The present invention relates to mining equiment field, particularly relate to a kind of single toggle jaw crusher.

Background technology

Single toggle jaw crusher is a kind of mining machinery for broken building stones, and its principle drives dynamic jaw group jaw to swing by drive train, moves jaw group and determine mutually to be engaged between jaw frame, two jaw movements of simulated animal, thus carry out crushing operation to material; In the process that dynamic jaw group jaw swings, adjusting mechanism for discharging hole is for supporting dynamic jaw group and the discharging opening regulating dynamic jaw group and determine between jaw frame, and dynamic jaw tension buffer gear is for straining dynamic jaw group and having buffering effect.

But existing single toggle jaw crusher exists the weak point of following several respects: 1, support body side plate is rigidly attached in gantry base, and damping effect is bad.2, two blocks of support body side plates are connected and fixed by frame pull bar, and frame pull bar can produce deflection due to frame vibrations, then axial rotation producing with support body side plate rubs, now, support body side plate is very easy to wearing and tearing, produces slight crack, thus has a strong impact on its service life.3, determine jaw frame and dynamic jaw group is rigidly fixed in main body by liner plate, do not have damping effect, thus when equipment runs, body can produce strenuous vibration, impact safety in production.4, dynamic jaw shaft assembly in dynamic jaw group and between supporting shaft holder assembling process complicated and dismounting is inconvenient, be embodied in bearing in dynamic jaw shaft assembly and sealing ring is all be set on eccentric shaft by interference after preheating, not only manufacturing procedure is complicated but also dismounting inconvenience, causes the regular maintenance of dynamic jaw group to bother.5, the structure of drive train is single, is all to arrange electrical machine belt pulley on the output shaft of drive motors, and electrical machine belt pulley is exported to dynamic jaw group by conveyer belt; Under this structure, the output shaft of drive motors is subject to the expanding force of conveyer belt, and Long-Time Service easily deformation occurs, and is just causing output shaft not, and conveyer belt transmits unstable and easily occurs the phenomenon that conveyer belt comes off.6, adjusting mechanism for discharging hole complex structure, installation bother and regulate inconvenience.7, dynamic jaw tension buffer gear all adopts spring and spring pull bar, strains dynamic jaw group by the restoring force of spring; But, swings spring all can be made to produce deformation because jaw breaks each jaw of the dynamic jaw group of machine, and hunting frequency is higher, thus make that spring deformation is too fast, temperature is higher, the effect of heating spring deteriorates, impact tension and buffering.
