Abstract
A padding apparatus for padding underground cable or pipeline is provided. The padding apparatus is adapted to continuously separate excavated material piled alongside an excavated ditch into relatively fine padding material and relatively rough residual material as the apparatus moves forward. The padding apparatus continuously places the relatively fine padding material in the ditch. According to the invention, the apparatus includes a frame for supporting and moving an endless openwork in an endless path for lifting excavated material in an elevating direction. The endless openwork has rods and transverse chain sections attached to the rods, whereby the rods and chain sections define openings that allow relatively fine padding material to pass therethrough. A discharge conveyor is positioned beneath at least a portion of the endless openwork of the separator to receive the relatively fine padding material and convey the padding material to the ditch for padding cable or pipeline therein.
