The specific embodiment
A kind of schreyerite jaw crusher, it is characterized in that: comprise frame, frame is provided with decides the jaw crushing shell, moving jaw, connecting rod, decide to form between jaw crushing shell and moving jaw broken cavity, moving jaw upper end is provided with the axle that is connected for frame, described small end is provided with eccentric shaft, eccentric shaft is provided with belt wheel, described connecting rod lower end is provided with for the forward thrust plate that connects connecting rod and moving jaw, described connecting rod lower end is provided with for the back thrust plate that connects connecting rod and frame, described moving jaw is provided with crushing shell, be provided with on the described working face of deciding jaw crushing shell and crushing shell and be parallel to each other and the bar shaped tooth of longitudinal extension, described bar shaped tooth comprises, The initial segment, interlude and ending segment, described ending segment is parallel with The initial segment to be staggered, and described interlude is connected between The initial segment and the ending segment.
The cross section of described bar shaped tooth is trapezoidal.
Two connection end shapes of described crushing shell are identical, and two connection end shapes of described crushing shell are identical.
Both sides, described connecting rod lower end are provided with the floor seat, moving jaw rear wall lower end is provided with the floor seat, the frame rear wall is provided with the floor seat, one end of described forward thrust plate, back thrust plate is supported on the floor seat, the other end of forward thrust plate is bearing on the floor seat of moving jaw rear wall lower end, and then the other end of thrust plate then is bearing on the floor seat of frame rear wall.
Crusher chamber is made of the huge truncated cylinder body up and down that crushing shell, movable crushing shell on the moving jaw and two blocks of side liner plates on the frame two side on the jaw are of deciding that is fixed on the frame.After the material that the is broken feeding crusher chamber, by the motion of moving jaw, be crusher chamber volume cyclomorphosis and finish fragmentation and the discharge of material.
Disintegrating machine has Motor Drive, drives belt wheel on the eccentric shaft by the band transmission, again by the rotation of crank, makes moving jaw in the disintegrating machine decide crushing shell on the jaw relatively and periodically draws close and separate.The structure of jaw crusher also must be considered the special construction requirement that is brought by its concrete running and design feature except satisfying conventional design criterions such as running, lubricated, installation, maintenance.Because broken load is the cycle sudden applied load, therefore the velocity perturbation in the necessary consideration running is regulated, and also can rationally utilize former moving technical ability so that motion is steady.In shattering process, may fall into non-broken material in the crusher chamber, therefore must consider the overload protection of machine.When requiring to change in the granularity of product, should consider to expect the adjusting device of mouth.When lock uint of floor and its supporting pad key etc.The crusher chamber of jaw crusher is to constitute by deciding jaw crushing shell and crushing shell.The crushing shell fixing and swinging jaw has manganese steel to make.Crushing shell is fixed in bolt and maple to be decided on jaw and the moving jaw.In order to improve crushing effect, the surface of two crushing shells all has longitudinal ripple, and is that convex-concave is relative.Like this, ore except granulitization is arranged, also had flecition.Manganese is also arranged on the both sides of disintegrating machine working space.Because the wearing and tearing of crushing shell are not uniformly, particularly maximum near the bottom wearing and tearing of send gape, therefore, often crushing shell is made relative up and down, in order to after the bottom weares and teares, its inversion is reused.The crushing shell of Large Crusher is to combine by many, and each piece can change mutually, so just can prolong the useful life of crushing shell.
Fit tightly in order to make crushing shell and moving jaw and to decide jaw, must be lined with the liner of being made by plastic material therebetween.Liner is made with kirsite or the big aluminium sheet of plasticity.Because it is not tight to fit, can cause very big local overload, be that crushing shell damages, fastening bolt is broken, even also can cause breaking of moving jaw.
Moving jaw is suspended on the axle, and axle then is supported in the sliding bearing on the frame side wall.The rich axle of moving jaw is made reciprocating swing to fixed jaw.
The swing of moving jaw realizes by means of crank and rocker mechanism.The crank double rocker mechanism is made up of eccentric shaft, connecting rod, forward thrust plate and thrust plate.Eccentric shaft is placed in the base bearing on the frame side wall, connecting rod then is contained on the eccentric part of eccentric shaft, one end of front and back thrust plate is supported on the connecting rod head grooves on two sides middle rib panel seat, the other end of forward thrust plate is bearing on the floor seat of moving jaw rear wall lower end, and then the other end of thrust plate then is bearing on the floor seat in the drift of frame rear wall.After eccentric wheel obtains to rotatablely move from motor by the V belt wheel, connecting rod is produced move up and down.Moving up and down and driving thrust plate of connecting rod moved.Because thrust plate constantly changes the angle of inclination, thereby make the rich axle swing of jaw.When moving upward, connecting rod carries out breaking ores.When connecting rod was positioned at the bottom extreme lower position, the angle of inclination that thrust plate becomes with horizontal line was 10--12
Back thrust plate is not only the rod member of transmission power, and is the breaking piece of disintegrating machine.When disintegrating machine fall into can not be broken object but machine when surpassing normal duty, back thrust plate fractures immediately, disintegrating machine just quits work, thereby avoids the damage of entire machine.
When connecting rod moves downward, keep often contact between jaw, thrust plate and the connecting rod mutually for making, thereby adopt with two pull bars and two take-up devices that spring is formed.Pull bar is articulated on the earrings of moving jaw lower end, and its other end is supported on the lower end of frame rear wall with spring.When moving jaw is swung forward, the inertia force that pull bar comes jaw balance and thrust plate to produce by spring.
Jaw crusher has impulse stroke and idle running stroke, so the load of motor is extremely uneven.In order to reduce the lack of uniformity of this load, at the two ends of eccentric shaft flywheel and belt wheel are housed.The belt wheel wheel effect of also taking off simultaneously.In the idle running stroke, flywheel stores energy get off, and energy is discharged in impulse stroke again.
Between frame rear wall and drift, put one group of pad with certain size.When changing the thickness of pad, can adjust the width of gape.
