Description
Technical field
The utility model relates to jaw crusher technical fields, and in particular to jaw crusher spring pull rod device.
Background technique
Jaw crusher the departments such as metallurgy, mine, building materials, capital construction be mainly used to carry out hard or middle hard material it is thick,
In be crushed, be also used as sometimes in other industrial departments fine crushing.When the motor of jaw crusher drives eccentric axis rotation
When, dynamic jaw upper end hangs on eccentric shaft, from bracket to front support certain angle behind lower end, makees periodical elliptical track pendulum
It is dynamic.When dynamic jaw swings to left dead point, very big moment of inertia is generated, which can make jaw separate with bracket and influence equipment
Normal operation.To prevent this phenomenon from occurring, it is equipped with spring pull rod device in dynamic jaw lower end, to guarantee that dynamic jaw and bracket are close
In conjunction with, and can the balanced dynamic jaw of part and the inertia force of bracket.
But the adjusting of spring pull rod device need to be often adjusted to ensure that dynamic jaw and bracket are combined closely in crusher operational process
The pretightning force of nut.And the spring pull rod device of conventional structure is because of adjusting nut end face and the direct face contact of spring capping, mutually
Between frictional resistance it is big, need biggish torque that could be turned.Meanwhile dynamic jaw lower end spring pull rod hooks seat and is cast as with dynamic jaw
One, is open hook-shaped connection between spring pull rod and dynamic jaw, in the bad working environments being chronically at more than dust and small particle
Under the conditions of, it will lead to dynamic jaw and hook to wear between seat and spring pull rod and aggravate, moving after jaw hooks seat fracture can only be carried out using welding form
Maintenance, is easy to produce welding stress working life and substantially reduces.And spring pull rod can separate moment with dynamic jaw when bracket fracture, phase
Part is closed to be scattered.So as to cause user's large labor intensity, it is not easy to adjust, the maintenance cost of equipment increases, and working efficiency reduces etc.
Bad result.
