Abstract
Shaker assemblies for dewatering slurries are disclosed. The shaker assemblies may include a positioning device which limits movement of the vibratory frame of the shaker assembly relative to a subframe when the vibratory frame is moved from a raised operating position to a lowered position. The positioning device may guide the vibratory frame as it is lowered from the raised position to the lowered position. In some embodiments, the shaker assembly includes a locking device for locking the vibratory frame to the subframe when the vibratory frame is in the lowered position.
Claims16
A shaker assembly for dewatering material, the shaker assembly comprising:
- a vibratory frame;
- a subframe that supports the vibratory frame;
- an isolation device for isolating vibration of the vibratory frame from the subframe, the isolation device being connected to the vibratory frame and the subframe, the isolation device initiating movement of the vibratory frame between a raised position in which a vibratory screen operates to dewater material and a lowered position in which the vibratory frame sits on the subframe;
- and
- a subframe guiding element connected to the subframe and a vibratory frame guiding element connected to the vibratory frame, the subframe guiding element being spaced from the vibratory frame guiding element, when the vibratory frame is in the raised position, the subframe guiding element further being positioned to contact the vibratory frame guiding element, when the vibratory frame is in the lowered position, to constrain movement of the vibratory frame relative to the subframe.
A shaker assembly for dewatering material, the shaker assembly comprising:
- a vibratory frame that supports a vibratory screen having openings for dewatering material that contacts the screen;
- a subframe that supports the vibratory frame, wherein the vibratory frame is moveable between a raised position and a lowered position in which the vibratory frame is secured to the subframe;
- a motor connected to the vibratory frame and operable to move the vibratory screen to dewater material, when the vibratory frame is in the raised position;
- an isolation device for isolating vibration of the vibratory frame from the subframe, the isolation device extending between the vibratory frame and the subframe;
- and
- a locking device mounted to the subframe and moveable between a locked position, when the vibratory frame is in the lowered position, in which the locking device engages the vibratory frame and secures the vibratory frame to the subframe and an unlocked position in which the locking device is disengaged from the vibratory frame allowing the vibratory frame to move relative to the subframe, the locking device being powered to extend and retract to move between the locked and unlocked positions.
