ABSTRACT:
A system for laying a trench bed layer consisting of fine grained material derived from unclassified fill material. The system includes a main frame that is pivotally supported by a hitch carried by a front end loader. The hitch includes a support bar that extends in the direction of travel of the front end loader whereby the main frame is securable to the support bar so as to extend transverse to the travel direction of the front end loader. Hydraulic cylinders normally used for manipulating the arms of the front end loader vary the attitude or angle of attack of the main frame in accordance with ground slope. The hitch also carries means for pivoting the main frame about a pin connection joining the main frame and the support bar. The system further includes a hopper carried by the main frame into which unclassified backfill material is loaded. A first conveyor transports the fill material from the bottom of the hopper to a vibrating screen. A second extendable and retractable conveyor is situated beneath the vibrating screen. The second conveyor is situated beneath the vibrating screen. The second conveyor receives only the fine particulate fraction of the original unclassified fill material which is sufficiently small to pass through the lower screen element and delivers this fine particulate fraction to the trench.
