Abstract
A crushing apparatus has an hydraulic cylinder for actuating a toggle mechanism connected to a moveable jaw. The apparatus may have a main frame with an opening near the top of the frame for admitting material to be crushed. There is a first jaw connected to the frame on one side of the opening by a first pivotal connection near the top of the jaw. A first toggle mechanism is operatively associated with the first jaw. There may also be a second jaw connected to the frame on a side of the opening opposite the first jaw by a second pivotal connection near the bottom of the second jaw. A second toggle mechanism is operatively associated with the bottom mounted jaw. The crushing apparatus may have a toggle mount which is movable towards or away from the associated jaw.
Claims21
A crushing apparatus, comprising:
- a main frame having a top;
- an opening near the top of the main frame for admitting material to be crushed;
- a first jaw having a top and being connected to the frame on one side of the opening by a first pivotal connection near the top of the jaw;
- a first toggle mechanism operatively associated with the top mounted jaw;
- a second jaw having a bottom and being connected to the frame on a side of the opening opposite the first jaw by a second pivotal connection near the bottom of the second jaw;
- and
- a second toggle mechanism operatively associated with the second jaw.
A crushing apparatus comprising:
- a main frame;
- an opening near the top of the frame for admitting material to be crushed;
- a pair of jaws mounted on the frame on opposite sides of the opening, at least one of the jaws being pivotally mounted to the frame;
- a toggle mechanism connected to the one jaw for moving the one jaw to crush material between the jaws, the toggle mechanism having a primary toggle with a first end pivotally mounted on the one jaw and a second end, and a secondary toggle having a first end pivotally mounted on the second end of the primary toggle and a second end pivotally mounted on a toggle mount movably mounted on the frame;
- and
- a hydraulic cylinder connected to the primary toggle near the second end thereof for powering the toggle mechanism.
