Abstract
Apparatus for processing of soil by vibratory sifting to remove rocks and other objects embedded in the soil provides a scoop for use with a backhoe or crawler tractor having a positionable boom. The scoop includes an elongated main frame to which are secured arcuately configured evenly spaced tines which extend downwardly from the main frame with sharp distal ends for readily penetrating the soil. By pivot arrangement, the main frame is secured to an outer end of the boom for placement upon the surface, the tines extending into the soil for processing. A hydraulic vibrator motor is coupled to the tines for causing vibratory sifting by the tines of the soil upon the main frame being pulled across the surface. Such operation sifts rocks and other objects from the soil. The apparatus is especially useful for processing the root medium after strip mining.
