Claim:
A scraping device comprising: a frame having a length defined between a first end and a second end; a tongue extending from the first end of the frame wherein the tongue has a length defined between a first end and a second end wherein the tongue has a top surface and a bottom surface and wherein the tongue is pivotally connected to the frame; first plates connected to the tongue wherein the first plates have top ends and bottom ends wherein the top ends are in a position opposite to the bottom ends wherein the first plates are connected adjacent to the top surface of the tongue and connected adjacent to the bottom surface of the tongue; second plates attached to the frame wherein the second plates have top ends and bottom ends wherein the top ends are in a position opposite to the bottom ends and further wherein the top ends of the first plates are located in a position relative to the top ends of the second plates wherein the bottom ends of the second plates are connected to the bottom ends of the first plates adjacent to the bottom surface of the tongue wherein the bottom ends of the second plates are connected to the bottom ends of the first plates by a pivot wherein pivotal connection of the bottom ends of the first plates to the bottom ends of the first plates allows the top ends of the first plates to move to a new position relative to the top ends of the second plates; and a cylinder connected to one of the top ends of the first plates adjacent to the top surface of the tongue and connected to one of the top ends of the second plates.
