ABSTRACT:
A scraping device, a system and a method for collecting a material are provided. The scraping device may have a bowl having a first end and a second end. A lip may be positioned at the first end and may cover an opening at the first end. In an embodiment, direct mounted cylinders may be attached to the lip and may move the lip to completely cover or uncover the opening. The scraping device may have a tongue mounted to the bowl having a triangular-shaped plate mechanism that may be used to raise and to lower a cutting edge attached to the bowl. Cylinders connected to the mechanism may be retracted or extended to raise or to lower the scraping device. A load within the scraping device may be lifted by force exerted from a barrel end of a cylinder, thus utilizing a maximum potential of the cylinder.
