Abstract
A first biasing element is positioned between an opening unit and a first frame for urging the opening unit downward. A lateral pivot combines the first biasing element to the first frame to allow for lateral movement in a horizontal plane of the opening unit. A first resilient device is positioned between the closing unit and the first frame to allow for lateral movement about a vertical axis of the closing unit and to urge the closing unit back to a neutral position. A second resilient device is positioned between the closing unit and the first frame to allow for vertical movement about a horizontal axis and to urge the closing unit back to a neutral position.
Claims26
A slurry injector comprising:
- a first frame;
- an opening unit for creating a trough;
- a hose positioned behind the opening unit for directing slurry into the trough;
- a closing unit positioned behind the hose for closing the trough;
- a first biasing element positioned between the opening unit and the first frame for urging the opening unit downward;
- a lateral pivot combining the first biasing element to the first frame to allow for lateral movement in a horizontal plane of the opening unit;
- a first resilient device positioned between the closing unit and the first frame to allow for lateral movement about a vertical axis of the closing unit and with respect to the opening unit and to urge the closing unit back to a neutral position, wherein the first resilient device is a torsion block comprising an outer casing comprising a plurality of sides;
- an inner tube comprising a plurality of sides;
- and a plurality of inserts each one of which is positioned between one of the plurality of sides of the inner tube and the outer casing.
A slurry injector comprising:
- a first frame;
- an opening unit for creating a trough;
- a hose positioned behind the opening unit for directing slurry into the trough;
- a closing unit positioned behind the hose for closing the trough;
- and
- a first biasing element positioned between the opening unit and the first frame for urging the opening unit downward, wherein the first biasing element is a torsion spring comprising a vertical extending portion attached to the first frame by a lateral pivot to allow the first biasing element to allow side-to-side pivoting motion of the opening unit.
A slurry injector comprising:
- a first frame;
- an opening unit for creating a trough;
- a hose positioned behind the opening unit for directing slurry into the trough;
- a second frame;
- a closing unit attached to the second frame and positioned behind the hose for closing the trough;
- and
- a second resilient device positioned between the closing unit and the second frame to allow for vertical movement about a horizontal axis with respect to the second frame and the first frame and to urge the closing unit back to a neutral position, wherein the second resilient device is a torsion block comprising an outer casing comprising a plurality of sides;
- an inner tube comprising a plurality of sides;
- and a plurality of inserts each one of which is positioned between one of the plurality of sides of the inner tube and the outer casing.
