Trolley dumper apparatus

1. An apparatus for depositing unconsolidated material into a receptacle, the apparatus comprising:

an elevated structure having a structure longitudinal axis, a proximal end and a distal end, and extending along the structure longitudinal axis from the proximal end to the distal end;

a trolley for travel along the elevated structure between the proximal end and the distal end;

a trolley bucket supported by the trolley for receiving a volume of unconsolidated material at the proximal end and discharging a volume of unconsolidated material into the receptacle; and

a high-lift structure, including a rotatable dumper lift movable between a first elevation and a second elevation greater than the first elevation, for lifting unconsolidated material from the first elevation to the second elevation, and discharging unconsolidated material into the trolley bucket at the proximal end;

wherein the rotatable dumper lift is configured to receive a first volume of unconsolidated material at the first elevation, lift the first volume of unconsolidated material from the first elevation to the second elevation, discharge the first volume of unconsolidated material into the trolley bucket at the second elevation, and return empty to the first elevation; and

wherein the trolley bucket is configured to discharge the first volume of unconsolidated material between the proximal and the distal ends into the receptacle positioned beneath the elevated structure while the rotatable dumper lift receives a second volume of unconsolidated material at the first elevation.

2. An apparatus for depositing unconsolidated material according to claim 1 wherein the trolley bucket is rotatable on the trolley about a trolley rotational axis and the rotatable dumper lift is rotatable about a pivot axis parallel to the trolley rotational axis.

3. An apparatus for depositing unconsolidated material according to claim 2 wherein the elevation of the trolley rotational axis is unchanging.

4. An apparatus for depositing unconsolidated material according to claim 3 wherein an elevation of the pivot axis is alternately above and below an elevation of the trolley rotational axis.

5. An apparatus for depositing unconsolidated material according to claim 1 wherein the high-lift structure is operably coupled with the elevated structure.

6. An apparatus for depositing unconsolidated material into a receptacle having a receptacle longitudinal axis, the apparatus comprising:

an elevated structure characterized by a structure longitudinal axis, a proximal end, and a distal end, and supporting a railway extending from the proximal end to the distal end parallel to the structure longitudinal axis;

a trolley having wheels for travel along the railway;

a trolley bucket, characterized by a trolley rotational axis, supported by the trolley, and rotatable about the trolley rotational axis relative to the trolley between a first orientation for receiving unconsolidated material, and a second orientation for discharging unconsolidated material into the receptacle positioned beneath the elevated structure with the receptacle longitudinal axis parallel to the structure longitudinal axis; and

a lift apparatus, including a rotatable dumper lift characterized by a pivot axis for lifting unconsolidated material to the trolley, and discharging unconsolidated material into the trolley bucket;

wherein unconsolidated material is dischargeable from the trolley bucket into the receptacle at selectable locations along the receptacle longitudinal axis without changing the elevation of the lift apparatus.

7. An apparatus for depositing unconsolidated material into a receptacle having a receptacle longitudinal axis, the apparatus comprising:

an elevated structure characterized by a structure proximal end, an opposed structure distal end, and a structure longitudinal axis extending through the structure proximal end and the opposed structure distal end;

at least one rail supported by the elevated structure, and parallel to the structure longitudinal axis, the at least one rail characterized by a rail proximal end and an opposed rail distal end;

a trolley movable on the at least one rail between the rail proximal end and the opposed rail distal end; and

a trolley bucket supported by the trolley and movable from a depositable orientation to a dischargeable orientation relative to the trolley;

wherein a volume of unconsolidated material in the trolley bucket is selectively dischargeable from the trolley bucket into the receptacle positioned beneath the elevated structure with receptacle longitudinal axis parallel to the structure longitudinal axis as the trolley moves on the at least one rail so that a generally uniform distribution of unconsolidated material in the receptacle is achieved.

8. An apparatus for depositing unconsolidated material according to claim 7 wherein the trolley bucket is rotatable on the trolley about a trolley rotational axis.

9. An apparatus for depositing unconsolidated material according to claim 8 wherein the trolley rotational axis is perpendicular to the structure longitudinal axis.

10. An apparatus for depositing unconsolidated material according to claim 7 further comprising a lift apparatus to lift volume of unconsolidated material to a position where it is depositable from above into the trolley bucket.
