Abstract

A push block, a scraping device and a method for collecting a material are provided. The scraping device has a frame, a blade attached to the bottom of the frame, a tongue attached to a front end of the frame and a beam attached to a back end of the frame. Tires are connected to the beam. The scraping device has a front lift mechanism at the front end of the frame and/or a rear lift mechanism at the back end of the frame. The front lift mechanism has a front cylinder connected to the tongue and the front end of the frame. The rear lift mechanism has a rear cylinder attached to the back end of the frame. Movement of the front cylinder and the rear cylinder results in raising and/or lowering of the corresponding ends of the frame of the scraping device. The push block is pivotally connected to an arm and pivotally connected to a tire beam. The arm and the tire beam are pivotally connected to the back end of the frame. Connections between the push block, the arm, the tire beam and the back end of the frame form corners of a parallelogram shape. The parallelogram shape enables the push block to maintain a consistent ground clearance if the frame raises or lowers relative to the ground and/or to the tire beam.
