Fig. 1 is the structural schematic diagram of the utility model hydraulic jaw crusher group.
As shown in Figure 1, hydraulic jaw crusher group provided by the utility model is HBY-100 type aggregate production equipment, core
Heart equipment is HBC1250 type jaw crusher, the specific rubbing board type batcher 1 of hydraulic jaw crusher group packet, oscillating feeder
2, vibrating screening machine 3, jaw crusher 4, belt conveyor 5, control system 6 and unified frame 7.Apron feeder 1, vibration
Batcher 2, vibrating screening machine 3, jaw crusher 4, belt conveyor 5, control system 6 are set in unified frame 7.
The angle of the apron feeder 1 and horizontal plane is 20 degree.Apron feeder 1 is that a kind of be tilted towards conveys material
Equipment, for angled conveyor up to 20 degree or so, loading machine loads lift height generally in 2m or so working efficiency highest, board-like feed
The hopper height of machine 1 is settable within this range, the direct feeding of loading machine is realized by apron feeder 1, without building feeding
Platform.
Oscillating feeder 2 is fed by vibration principle.
Vibrating screening machine 3 is provided with mesh, and satisfactory material is carried out prescreening, jaw crusher is effectively reduced
Load.
Belt conveyor 5 is II type belt conveyor of DT.
Jaw crusher 4 uses deep chamber for the crusher jaw plate structure of hyperboloid lumen type.Jaw crusher 4 is mainly by mainframe
Structure, moving jaw plate, determines jaw, eccentric shaft, flywheel, tension rail block, hydraulic and lubricating system, elbow seat and bracket, drives jaw ontology
The components such as moving axis, bearing block, shield and anti-gray are constituted.Main frame structure is the basis for integrating each component, flywheel, jaw (dynamic jaw
Plate determines jaw), elbow seat and bracket, bearing block be installed on main frame structure.Moving jaw plate use is hingedly connected to jaw ontology
On, jaw ontology is connect with eccentric shaft and flywheel.Drive shaft uses self-aligning double-row cylinder roller bearing, and there are reasonable
Axial gap.The large carrying capacity of bearing can automatically adjust misalignment of axe when axis working deformation, and in reasonable axial
Within the scope of vibration, optimum condition is maintained." above pushing away " elbow of eccentric position design and the special angle design of eccentric shaft on flywheel
Plate locations of structures and moving jaw plate and the hyperboloid breakup mode for determining jaw formation, make moving jaw plate curve movement form comprehensive fortune

Moving jaw plate starts to move upwards in the moving jaw plate of machine and common jaw crusher.(dotted line indicates post exercise as shown in Figure 5
The position of the moving jaw plate of hydraulic jaw crusher).Moving jaw plate in Fig. 5 is hydraulic compared with the initial position of the moving jaw plate in Fig. 2
The jaw mouth of jaw crusher all opens, and the degree opened is less than the journey that the jaw mouth of common jaw crusher all opens
Degree, and the lower half portion position E Kou when the position of lower half portion jaw mouth and initial position essentially coincides；And common jaw is broken
Broken machine lower half portion jaw mouth becomes smaller, and the lower half portion of moving jaw plate begins participating in broken, i.e., only moving jaw plate moves upwards and just starts
It is broken, and participate in the lower half portion of broken only moving jaw plate.
Moving jaw plate continues to move in the moving jaw plate of hydraulic jaw crusher and common jaw crusher, is restored to initial
Position.
The utility model uses hydraulic station for the feeding device, screening plant, the jaw crusher, described defeated
Device is sent to provide operating oil pressure.Traditional jaw crusher generally uses motor+pulley drive, when progress material is broken, activity
The adjustment of the gap of jaw and fixed jaw is adjusted by spring, and noise is big when broken material；The hydraulic jaw of the utility model is broken
Unit provides power using hydraulic system, and jaw gap adjustment is also hydraulic control.No matter idle running or load running, liquid
Pressure system operation noise is superior to motor drive.
