Abstract:

A ground-cleaning apparatus for separating debris from soil according to the invention includes a paddle assembly, a separation bin, and a hydraulic assembly, each mounted on a chassis having a front frame and a rear frame. The paddle assembly is rotatably supported on the front frame and includes paddles for agitating the ground surface and carrying soil and debris to the separation bin. The separation bin is supported on the rear frame and includes a sifting screen partially surrounded by sidewalls and a rear wall. The hydraulic assembly includes a selectively actuated piston and cylinder assembly for reciprocating the separation bin. Paddles agitate the ground surface and deposits the soil and debris on the separation bin, where the debris is trapped by the sifting screen and the soil passes through the sifting screen as the separation bin is reciprocated by the piston and cylinder assembly.
