Abstract

A pipeline padding machine for use with a motorized carrier is mounted on a flat bed trailer adapted to be hitched to the carrier. Collector apparatus mounted beneath the screening apparatus receives the earth from a discharge at the bottom of the screening apparatus and conveys it to its discharge end which is located laterally of the carrier-trailer when the screening apparatus is in a transverse operational mode. A delivery apparatus pivotally mounted at a receiving end beneath the discharge end of the collector apparatus may in turn receive the earth discharged for delivery at greater distances from the screening apparatus. This delivery apparatus may be supported at its discharge end from the carrier or the trailer so that its discharge end may be located laterally of the carrier-trailer at a selected distance from the carrier-trailer within a variable range of distances. The screening apparatus preferably has two transverse operational modes so that undesirable objects and materials may be discharged to either side of the carrier-trailer depending on the mode selected. The collector apparatus is preferably reversible, so that relatively fine materials may be optionally discharged to either the same or the opposite side of the machine as the undesirable materials and objects. The delivery apparatus preferably is pivotally connectable beneath either end of the collector apparatus so that fine materials can be delivered to distant points from either side of the padding machine in either transverse operational mode and regardless of the direction of the collector apparatus.

Claims

1. A padding machine to be towed behind a motorized carrier comprising:

transport means adapted to be hitched to said carrier;

seat means disposed on said transport means;

bearing means nestled in said seat means;

support means mounted on said bearing means above said transport means;

hopper means mounted on said support means having a bottom with a first discharge port therein;

separator means for catching relatively large stones and debris in earth fed into said hopper means and for passing separated materials therethrough;

sift means mounted in said hopper means beneath said separator means for catching relatively medium size stones and debris passing through said separator means and for passing sifted materials through said sift means and said first discharge port;

discharge means for distributing stones and debris caught by said sift means outwardly of said hopper means;

collection means mounted beneath said hopper means for receiving said sifted materials passing through said sift means and said first discharge port and for conveying said sifted materials outwardly in relation to said hopper means to a discharge end of said collection means; and

delivery means for conveying said sifted materials from said discharge end of said collection means to a discharge end of said delivery means.

2. A padding machine according to claim 1 further comprising a suspension means adapted to extend from said carrier for supporting said discharge end of said delivery means laterally of said carrier at a variable range of distances.

3. A padding machine according to claim 1 further comprising a suspension means adapted to extend from said trailer for supporting said discharge end of said delivery means laterally of said trailer at a variable range of distances.

4. A padding machine to be towed behind a motorized carrier comprising:

an elongated transport means having a forward end adapted to be hitched to said carrier, a rear end supported above ground by a wheel means and a seat means therebetween;

an elongated support means spaced above said transport means by a bearing means nestled in said seat means;

an elongated hopper means mounted on said support means in an inclined relationship to said transport means and having a bottom with a discharge port;

an inclined collection means mounted on said support means beneath said hopper means and aligned with said discharge port;

separating means for catching relatively large stones and debris in earth fed into said hopper means and for passing remaining materials therethrough;

an inclined vibrating screen means mounted in said hopper means beneath said separating means for catching relatively medium size stones and debris passing through said separating means and for passing remaining materials through said screen means and through said discharge port onto said collection means;

a discharge means extending from said hopper means for distributing stones and debris caught by said screen means outwardly of said hopper means;

a delivery means for transporting said remaining materials passed through said screen means from a discharge end of said collection means to a point laterally and forwardly of said carrier; and

a suspension means extending from said carrier for supporting said delivery means and for varying the location of said point along an arc about the discharge end of said collection means.
