Mobile screen assembly for rubble and debris

A vehicle for feeding and screening material comprising an elongate vehicle frame having hitch structure for detachably connecting the frame to a towing vehicle, wheel means providing wheel support for the frame,

• an elongate inclined power-driven material-transport conveyor extending lengthwise along the vehicle frame having a feed end adjacent one end of the vehicle frame and a raised discharge end located toward the vehicle's opposite end,
• an inclined screen assembly having a feed end adjacent and in receiving relation to the discharge end of the material-transport conveyor and inclining downwardly form its feed end to a discharge end disposed adjacent the vehicle's opposite end,
• the screen assembly having at least two decks and including an upper deck retaining the coarse material supplied to the screen assembly by the material-transport conveyor and a lower deck retaining material of smaller size than the material retained by the upper deck,
• material-channelling structure mounted on the vehicle frame in receiving relation to the upper deck of the screen assembly and constructed to channel material deposited on the structure beyond said opposite end of the vehicle frame, and
• an adjustable conveyor adjustably mounted on the vehicle frame and adjustable from an inoperative position to an extended position extending laterally of the vehicle frame, the adjustable conveyor receiving material retained on the lower deck of the screen assembly.

A vehicle for feeding and screening material comprising:

• an elongated vehicle frame and wheel support for the frame,
• an elongate inclined power-driven material-transport conveyor extending lengthwise along the vehicle frame having a feed end adjacent one end of the vehicle frame and a discharge end located toward the vehicle's opposite end,
• a material-receiving hopper disposed over the feed end of the material-transport conveyor,
• an inclined screen assembly having a feed end adjacent the discharge end of the material-transport conveyor and inclining downwardly toward a discharge end located adjacent the vehicle's opposite end,
• an adjustable conveyor supported on the vehicle frame an adjustable from an inoperative position to an extended position extending laterally of the vehicle from a feed end which is in material-receiving relation to the discharge end of the screen assembly, and
• an under-screen conveyor mounted on the vehicle frame in a position beneath the screen assembly with a feed end adjacent the discharge end of the screen assembly and extending from said feed end to a discharge end located toward the vehicle's said one end.

• an inclined screen assembly having a feed end adjacent and in receiving relation to the discharge end of the material-transport conveyor and inclining downwardly from its feed end and progressing toward the vehicle's opposite end to a discharge end for the screen assembly which is disposed adjacent the vehicle's opposite end,
• the screen assembly having at least two decks and including an upper deck retaining the course material supplied to the screen assembly by the material-transport conveyor and a lower deck retaining material of smaller size than the material retained by the upper deck,
• material retained on the upper deck and on leaving the upper deck being directed beyond said opposite end of the vehicle frame, and
• an adjustable conveyor adjustably mounted on the vehicle frame and adjustable between an inoperative position and an extended position extending laterally of the vehicle frame, the adjustable conveyor receiving material retained on the lower deck of the screen assembly.
