  • Patent number: 5097610
    Abstract: A compact padding machine for screening and conveying soil into a trench. The machine is usable as an attachment to a conventional bucket loader, bulldozer or other base machine. The padding machine includes a screening belt, an underlying inclined conveyor belt, and a transverse, extendible discharge conveyor belt. Soil is collected and conveyed upwardly on the screening belt. Fine grained soil passes through the screening belt, is deposited onto the inclined conveyor belt, and is discharged therefrom onto the transverse conveyor belt, from where it may be conveyed into an adjacent trench. A hydraulic vibrator is coupled to the screening belt to disaggregate clods of fine-grained soil and cause the soil to pass through the screening belt. Rocks and other large objects are conveyed to the rear of the machine and discharged.
