Abstract
A material handling system is provided that allows for the even distribution and increased fill percent of a container without the need for personnel to manually even out the distribution of the material, and contains and protects material from the environment. The system deposits and levels material into an open-top container, and may include a leveler comprising a cover, a screw coupled to the cover, and a trough. The screw may be a shafted screw and the trough may be a bottomless trough. A hydraulic piston may be coupled to the cover and a support structure may both support and move the cover of the leveler.
Claims16
An overhead material handling system comprising:
- a leveler comprising a cover defining an interior, the cover interior comprising an uninterrupted volume including a bottomless trough, and a shafted screw having a shaft and a screw portion positioned within the cover interior;
- a support structure pivotally supporting the cover of the leveler and configured to move the leveler between a raised position and a lowered position thereby positioning the leveler substantially parallel to a container;
- a plurality of inspection holes formed through a top surface of the cover;
- and
- a guide rail and a stopping plate configured to position the container under the cover;
- wherein the uninterrupted volume of the cover spans the opening of the container when in the lowered position.
A method comprising:
- positioning a container under a cover via a guide rail and a stopping plate;
- receiving material through an inlet into an uninterrupted volume within the cover of a leveling system, the uninterrupted volume spanning the width of the cover;
- rotating a shafted screw, having a shaft and a screw portion, within the volume to direct the received material around the shafted screw;
- releasing the material through an open bottom of the volume;
- filling a first compartment of the container with the material;
- pushing additional material past the first compartment and into a second compartment within the container;
- and
- detecting cover movement and orientation.
A leveling apparatus for distributing and leveling material comprising:
- a body portion comprising a removable cover, wherein the removable cover is coupled to at least one hydraulic piston and wherein the at least one hydraulic piston functions to pivot the removable cover about an axis, the removable cover defining an uninterrupted volume thereunder extending from one side of the cover to the opposite side;
- and
- a plurality of inspection holes formed through a top surface of the removable cover;
- and
- a shafted screw, having a shaft and a screw portion and being positioned within the volume under the cover, wherein the shafted screw is removably attached to a drive unit.
