Description
Technical field
It is mechanical that the utility model relates to a kind of rubbles, specially a kind of vibration damping jaw ore crusher.
Background technique
Ore crusher can be transported extensively is able to numerous portions such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry
Door.Crusher can be roughly classified into two major classes according to the mode that crushing force acts on by ore crusher: crusher and ore mill.
Selectable crushing plant is processed in ore reduction to be had: gyratory crusher, jaw crusher, impact breaker, hammer mill,
The equipment such as kibbler roll, impact crusher, compound crusher；Ore milling, which processes selectable milling equipment, to be had: high
Press the milling equipments such as suspension mill, raymond mill, trapezoidal flour mill, tricyclic micropowder grinding, ball mill, superfine mill.Its
In, jaw crusher is one kind most widely used on the market, its working principle is that: motor drive belt and belt pulley,
Jaw is set to move up and down by eccentric shaft, angle becomes larger between bracket and dynamic jaw when dynamic jaw rises, to push moving jaw plate to calmly
Jaw is close, and material is crushed or grinds, rubs with the hands and reach broken purpose at the same time；When dynamic jaw downlink, angle between bracket and dynamic jaw
Become smaller, moving jaw plate leaves under the action of pull rod, spring determines jaw, and broken material mouth under crusher chamber is discharged for this, with electricity
Motivation continuous rotation and be crushed motor-driven jaw and make periodically crushing and excretion material, realize batch production, this stone crusher is because having
Structure is simple, reliable operation and can crushing hard material the advantages that and by deserved with ore dressing, construction material, silicate and pottery extensively
The industrial departments such as porcelain.
This jaw ore crusher bears torque in the process of running or vibration is larger, often will cause transmission system event
Barrier common are the loosening of lower margin bolt or breakage problem, because most of ore crusher passes through bolt and pedestal in market at present
Between be fixedly connected, do not have resiliency, since crusher is driven by eccentric shaft, so can generate compared with favourable opposition at work
Vibration is hit, to be easy to cause the lower margin bolt of fixed crusher to loosen after long-term work, and then influences the normal work of crusher
Make, and bearing portion is also the component for being easiest to damage, because wearing in use bigger needing often maintenance, warp
Often refueling just can increase the service life of bearing.
Utility model content
The main purpose of the utility model is to provide a kind of vibration damping jaw ore crushers, and it is broken to be addressed jaw ore

The problem of foot bolt is loosened or is broken, improves impact resistance.
To achieve the above objectives, the technical solution adopted in the utility model are as follows: a kind of vibration damping jaw ore crusher includes
Rack, determines jaw, eccentric shaft and snubber base at dynamic jaw；The rack is four wall rigid frames of upper and lower opening, upper opening be equipped with into
Material mouth, under shed are equipped with discharge port, and the rack is used as the reaction force for supporting the eccentric shaft and bearing broken building stones；It is described
The relative motion for determining jaw and the dynamic jaw is able to comminuting matter, and the dynamic jaw hangs on the eccentric shaft, described to determine jaw and be located at institute
State rack antetheca；The rotation of the eccentric shaft is able to that dynamic jaw is driven to move up and down, and described eccentric shaft one end fills belt wheel, other end dress
Flywheel；The snubber base offsets the eccentric shaft institute by the fixed rack of foundation bolt, the tension of the snubber base
The impact force of generation, the snubber base include the damper of Base body, cushion blocking and the upward tension of offer, the pedestal master
Body includes bottom plate, supporter, and the bottom plate is parallel to ground, and two supporters, the support is arranged in the bottom board symmetry
Body extends upwardly to the frame wall of the rack, and the supporter, which is distributed in supporter described in the discharge port two sides and is provided with, to be put
Set the groove of the damper；The cushion blocking is rubber pad, is set between the rack and the supporter, is able to vibration damping
And sound insulation；The damper connects the rack and the Base body, be able to by increase tension make foundation bolt by
To when downward impact, offsets the impact force generated by the eccentric shaft and be unlikely to so that the clamp force of foundation bolt be made to make up automatically
Foundation bolt is set to loosen or be broken.
Preferably, the spacing distance between the supporter is not less than the width of the discharge port.
Preferably, the snubber base further comprises striker plate, the striker plate be able to protection building stones enter it is described
Damper, the striker plate are arranged between the discharge port and the damper, and described striker plate or so extends to the branch
Support body, the striker plate extend upwardly to the rack.
Preferably, the snubber base is concreting.
It has the beneficial effect that by the way that snubber base is arranged on jaw ore crusher, increases tension and make foundation bolt tight
