DEFINITION

Classification: 171/126

(under subclass 124) Apparatus including an interstitial or reticulated surface which receives excavated earth with buried objects therein and which surface is movably supported in order to assist in separating the objects from the earth and/or to transport said objects during the separating operation.

(1) Note. Included herein are those reticulated separating surfaces formed of a continuous endless belt, band or conveyor flight and not provided for below.

110, for excavating means having a belt-type separating conveyor intimately associated therewith, where the excavating means and conveyor are adjustable together relative to a supporting chassis.
