Description

Single toggle jaw crusher

Technical field

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

Background technology

Single toggle jaw crusher is a kind of mining machinery for crushing building stones, and its principle is to drive by drive train to move Jaw group jaw swings, dynamic jaw group and determine to be mutually twisted between jaw frame, simulates two jaw movements of animal, thus crushing to material Operation；During dynamic jaw group jaw swings, adjusting mechanism for discharging hole is used for supporting dynamic jaw group and adjusting dynamic jaw group and determine jaw Discharging opening between frame, dynamic jaw tension buffer gear is used for straining dynamic jaw group and having buffering effect.

But, there is the weak point of following several respects in existing single toggle jaw crusher：1, support body side plate is to be rigidly connected In gantry base, damping effect is bad.2, two block frame side plates are connected by frame pull bar, and frame pull bar can be due to machine Frame shake and produce deflection, then axial rotation and with support body side plate produce friction, now, support body side plate be very easy to abrasion, Produce slight crack, thus having a strong impact on its service life.3, determine jaw frame and be rigidly fixed in main body by liner plate with dynamic jaw group, do not have There is damping effect, thus when equipment runs, body can produce strenuous vibration, impact safety in production.4, the dynamic jaw in dynamic jaw group Between shaft assembly and supporting shaft holder, assembling process is complicated and dismounts inconvenience, is embodied in bearing in dynamic jaw shaft assembly and close Seal is all that interference is set on eccentric shaft after preheating, and not only manufacturing procedure is complicated but also dismantle inconvenience, leads to dynamic jaw group Regular maintenance trouble.5, the structure of drive train is single, is all setting electrical machine belt pulley, motor on the output shaft of motor Belt wheel is exported to dynamic jaw group by conveyer belt；Under this structure, the output shaft of motor is subject to the expanding force of conveyer belt, for a long time Using being susceptible to deformation, just do not leading to output shaft, conveyer belt transmission is unstable and the phenomenon that conveyer belt comes off easily.6, Adjusting mechanism for discharging hole complex structure, installation trouble and regulation inconvenience.7, dynamic jaw tension buffer gear is all using spring and spring Pull bar, strains dynamic jaw group by the restoring force of spring；But, all can make bullet because each jaw of dynamic jaw group that jaw breaks machine swings Spring produces deformation, and hunting frequency is higher, so that spring deformation is too fast, temperature is higher, heating spring is aging, impact tension Effect with buffering.
