Abstract

A rail car unloading device is provided comprising a base, a hopper, and a support member. The base comprises a support plate. The support member is rotatably mounted to the base support plate. The hopper is mounted to the support member and the support member is rotatable with respect to the base between a first position where the hopper is placed beneath a rail car in an unloading position and a second position where the hopper is positioned in substantially parallel alignment with rail tracks such that a rail car may pass by the device.

Claims

1. A device for unloading a rail car on rail tracks, the device comprising:

a base comprising a track formed therein;

a substantially vertical support member rotatably mounted to said base, said support member comprising;

at least one vertical support leg;

at least one wheel rotatably mounted to said at least one vertical support leg and configured for engagement with said track; and

a base engaging member configured for rotatable engagement with said base, said base engaging member and said at least one wheel configured to allow rotation of said support member with respect to said base; and

a conveyor mounted to said support member, said conveyor comprising a hopper, said support member configured to rotate between a first position where said hopper is positioned under the rail car and a second position where said hopper and said conveyor are in substantially parallel alignment with the rail tracks such that the rail car may pass by said device.

2. A rail car unloading device in accordance with claim 1 further comprising a conveyor drive for actuating at least a portion of said conveyor, wherein an inlet of said conveyor is coupled to said hopper.

3. A rail car unloading device in accordance with claim 2 wherein upon rotation of at least a portion of said conveyor by said conveyor drive, said conveyor conveys material unloaded from the rail car into said hopper away from said hopper.

4. A rail car unloading device in accordance with claim 1 wherein said conveyor is an auger.

5. A rail car unloading device in accordance with claim 1 further comprising at least one of a lift system and a conveyor actuator for moving said conveyor with respect to said support member.

6. A rail car unloading device in accordance with claim 5 wherein said conveyor is pivotably coupled to at least one of said hopper and said support member, wherein said conveyor is configured to pivot with respect to said support member when moved by said actuator.

7. A rail car unloading device in accordance with claim 1 further comprising a hopper actuator configured to move said hopper with respect to said support member.

8. A rail car unloading device in accordance with claim 7 wherein said hopper actuator is configured to raise and lower said hopper with respect to the rail car.

9. A bulk storage container unloading device comprising:

a base comprising a support plate;

a support member rotatably mounted to said support plate about an axis perpendicular to said base; and

a hopper mounted to said support member, said support member rotatable to a first position where said hopper is positioned beneath a discharge opening of a bulk storage container; and

a hopper actuator configured to move at least said hopper with respect to said support member.

10. A bulk storage container unloading device in accordance with claim 9 wherein said support member is rotatable to a second position wherein said device hopper is positioned such that the bulk storage container may be moved without interference from said unloading device.

11. A bulk storage container unloading device in accordance with claim 9 further comprising a conveyor mounted to at least one of an output of said hopper and said support member.

12. A bulk storage container unloading device in accordance with claim 9 wherein said hopper actuator is configured to raise and lower said hopper with respect to the bulk storage container.

13. A bulk storage container unloading device in accordance with claim 9 further comprising a base drive for rotating said support member about the axis perpendicular to said base.

14. A rail car unloading device comprising:

a base comprising a support plate;

a support member rotatably mounted to said support plate; and

a hopper mounted to said support member, said support member rotatable between a first position where said hopper is positioned beneath a rail car for unloading and a second position where said hopper is positioned in substantially parallel alignment with rail tracks such that the rail car may pass by said device; and

a hopper actuator configured to move at least said hopper with respect to said support member.

15. A rail car unloading device in accordance with claim 14 further comprising a conveyor mounted to at least one of said hopper and said support member, and a conveyor drive coupled to said conveyor and configured to actuate at least a portion of said conveyor.

16. A rail car unloading device in accordance with claim 14 further comprising a base drive for rotating said support member with respect to said base between the first position and the second position.

17. A rail car container unloading device in accordance with claim 14 wherein said hopper actuator is configured to raise and lower said hopper with respect to the rail car.

18. A rail car unloading device in accordance with claim 15 further comprising at least one of a lift system and a conveyor actuator for moving said conveyor with respect to said support member.
