Abstract

There is disclosed a waste collecting device having a container for receiving waste therein. The container has an end wall and an ejector panel. The container encloses a waste receiving volume. The ejector panel has an opening therethrough for allowing access to the waste receiving volume for receiving the waste. The waste collecting device further has a compactor outside the waste receiving volume being operable for pushing the waste in the container through the opening. The ejector panel is movable within the waste receiving volume and relative to a floor of the container for pushing the waste out of the waste receiving volume. A method of operating a waste collecting device is also disclosed.

First claim

What is claimed is:

1. A waste collecting device configured for use mounted on a vehicle, the waste collecting device comprising:
a container for receiving waste therein, the container having a first end and a second end spaced apart from the first end along a longitudinal axis, the container comprising:
an end wall located at the first end; and
an ejector panel, the container enclosing a waste receiving volume between the end wall and the ejector panel, wherein the ejector panel is configured to push waste through and out of the waste receiving volume during an unloading sequence by moving along the longitudinal axis between the first and second ends within the waste receiving volume and relative to a floor of the container;

a compactor located adjacent the second end of the container outside the waste receiving volume, the compactor operable for pushing the waste in the container through an opening in the ejector panel into the waste receiving volume;
a blocking device coupled to the ejector panel and configured to move along a direction perpendicular to the longitudinal axis between a first position, in which the blocking device inhibits waste in the waste receiving volume from entering the opening as the ejector panel moves along the longitudinal axis, and a second position, in which waste is uninhibited from entering the waste receiving volume through the opening; and
a wall extending outward from a surface of the ejector panel and surrounding the opening in the ejector panel, the wall forming a cylindrical conduit configured to guide waste towards the waste receiving volume.

2. The waste collecting device of claim 1 , wherein a footprint area of the ejector panel corresponds to an internal cross-sectional area of the container taken perpendicularly to the longitudinal axis.

3. The waste collecting device of claim 1 , wherein the end wall is a door pivotally mounted to a remainder of the container, the door being pivotable between a closed position and an opened position, the door allowing access to the waste receiving volume in the opened position for unloading the container.

4. The waste collecting device of claim 1 , wherein the blocking device comprises at least one stem that extends through the opening in the first position and is offset from the opening in the second position.

5. The waste collecting device of claim 1 , wherein the blocking device comprises two parallel stems, wherein each of the two parallel stems extends through the opening in the first position and is offset from the opening in the second position.

6. The waste collecting device of claim 1 , wherein the compactor is a screw conveyor rotatable along a rotation axis, the screw conveyor including a screw in driving engagement with a motor.

7. The waste collecting device of claim 1 , further comprising a motor secured to the ejector panel, the motor being in driving engagement with rails secured to lateral walls of the container, the rails and the lateral walls extending between the first end and the second end, the motor operable to move the ejector panel relative to the rails.

8. The waste collecting device of claim 1 , wherein the wall extends from the surface of the ejector panel towards the second end of the container.

9. The waste collecting device of claim 8 , wherein:
the container further comprises a second end wall located at the second end, the second end wall defining a waste opening therethrough; and
the wall extending from the ejector panel is configured to cooperate with the waste opening through the second end wall.

10. A vehicle for collecting waste, the vehicle comprising:
a frame; and
a waste collecting device secured to the frame, the waste collecting device comprising:
a container for receiving waste therein, the container having a first end and a second end spaced apart from the first end along a longitudinal axis, the container comprising:
an end wall located at the first end; and
an ejector panel, the container enclosing a waste receiving volume between the end wall and the ejector panel, wherein the ejector panel is configured to push waste through and out of the waste receiving volume during an unloading sequence by moving along the longitudinal axis between the first and second ends within the waste receiving volume and relative to a floor of the container

a compactor located adjacent the second end of the container outside the waste receiving volume, the compactor operable for pushing the waste in the container through an opening in the ejector panel into the waste receiving volume;
a blocking device coupled to the ejector panel and configured to move along a direction perpendicular to the longitudinal axis between a first position, in which the blocking device inhibits waste in the waste receiving volume from entering the opening as the ejector panel moves along the longitudinal axis, and a second position, in which waste is uninhibited from entering the waste receiving volume through the opening; and
a wall extending outward from a surface of the ejector panel and surrounding the opening in the ejector panel, the wall forming a cylindrical conduit configured to guide waste towards the waste receiving volume.

11. The vehicle of claim 10 , wherein a footprint area of the ejector panel corresponds to an internal cross-sectional area of the container taken perpendicularly to the longitudinal axis.

12. The vehicle of claim 10 , wherein the end wall is a door pivotally mounted to a remainder of the container, the door being pivotable between a closed position and an opened position, the door allowing access to the waste receiving volume in the opened position for unloading the container.

13. The vehicle of claim 10 , wherein the blocking device comprises at least one stem that extends through the opening in the first position and is offset from the opening in the second position.

14. The vehicle of claim 10 , wherein the blocking device comprises two parallel stems, wherein each of the two parallel stems extends through the opening in the first position and is offset from the opening in the second position.

15. The vehicle of claim 10 , wherein the compactor is a screw conveyor rotatable along a rotation axis, the screw conveyor including a screw in driving engagement with a motor.

16. The vehicle of claim 10 , further comprising a motor secured to the ejector panel, the motor being in driving engagement with rails secured to lateral walls of the container, the rails and the lateral walls extending between the first end and the second end, the motor operable to move the ejector panel relative to the rails.

17. The vehicle of claim 10 , wherein the wall extends from the surface of the ejector panel towards the second end of the container.

18. The vehicle of claim 17 , wherein:
the container further comprises a second end wall located at the second end, the second end wall defining a waste opening therethrough; and
the wall extending from the ejector panel is configured to cooperate with the waste opening through the second end wall.
