FIELD OF THE INVENTION
The present invention relates generally to apparatuses and methods for rock crushers, and particularly to apparatuses and methods for jaw crushers.
BACKGROUND AND DESCRIPTION OF THE PRIOR ART
It is known to use apparatuses and methods to crush rocks. Conventional apparatuses and methods, however, suffer from one or more disadvantages. For example, conventional apparatuses and methods either have a toggle plate/wedge adjust assembly or a tramp iron relief system. Conventional apparatuses and methods cannot be easily converted between a toggle plate/wedge adjust assembly and a tramp iron relief system. Conventional apparatuses and methods are also undesirably large and expensive. Conventional apparatuses and methods also do not indicate the position of the rock crusher in the absence of a full control system.
It would be desirable, therefore, if an apparatus and method for a rock crusher could be provided that would be capable of using either a toggle plate/wedge adjust assembly or a tramp iron relief system. It would also be desirable if such an apparatus and method for a rock crusher could be provided that would easily be converted between a toggle plate/wedge adjust assembly and a tramp iron relief system. It would be further desirable if such an apparatus and method for a rock crusher could be provided that would be more compact and less expensive. It would be still further desirable if such an apparatus and method for a rock crusher could be provided that would indicate the position of rock crusher in the absence of a full control system.
Advantages of the Preferred Embodiments of the Invention
Accordingly, it is an advantage of the preferred embodiments of the invention claimed herein to provide an apparatus and method for a rock crusher that can use either a toggle plate/wedge adjust assembly or a tramp iron relief system. It is also an advantage of the preferred embodiments of the invention claimed herein to provide an apparatus and method for a rock crusher that is easily converted between a toggle plate/wedge adjust assembly and a tramp iron relief system. It is another advantage of the preferred embodiments of the invention claimed herein to provide an apparatus and method for a rock crusher that is more compact and less expensive. It is yet another advantage of the preferred embodiments of the invention claimed herein to provide an apparatus and method for a rock crusher that indicates the position of the rock crusher in the absence of a full control system.
Additional advantages of the preferred embodiments of the invention will become apparent from an examination of the drawings and the ensuing description.
