APPARATUS AND METHOD FOR AN APRON ASSEMBLY

摘要

An apron assembly comprising an apron mounted to the crusher and adapted to be moved between an operating position and an open position, a tension rod operatively attached to and disposed between the shock absorber mount and the apron, a spring seat mounted to the crusher and adapted to be moved between a raised position and a lowered position, a spring operatively disposed between the tension rod base and the spring seat, an actuator mounted to the crusher and the spring seat and adapted to be moved between a retracted position and an extended position, a shock absorber operatively attached to and disposed between the spring seat and a shock absorber mount. The shock absorber reduces the pressure applied to the actuator. A method for controlling the opening in a crusher comprising providing an apron assembly and moving the shock absorber between a retracted position and an extended position.

1. An apron assembly adapted for use on a crusher, said apron assembly comprising:
(a) an apron, said apron being mounted to the crusher and being adapted to be moved between an operating position and an open position; (b) a tension rod, said tension rod being operatively attached to and disposed between the apron and a shock absorber mount and said tension rod having a tension rod base; (c) a spring seat, said spring seat being mounted to the crusher and being adapted to be moved between a raised position and a lowered position; (d) a spring, said spring being operatively disposed between the tension rod base and the spring seat; (e) an actuator, said actuator being mounted to the crusher and the spring seat and being adapted to be moved between a retracted position and an extended position; (f) a shock absorber, said shock absorber being operatively attached to and disposed between the spring seat and the shock absorber mount; wherein the shock absorber reduces the pressure applied to the actuator.
