  • Patent number: 4832553
    Abstract: Disclosed is a method and apparatus for lifting and stacking cartons onto a bed attached to a truck bed, especially in an agricultural field. The lifting apparatus includes two endless parallel belts to lift the cartons from the field onto a first conveyor. Variations in carton size or alignment may be accommodated by a pivoting loading frame or by lateral movement of the loader, which lateral movement is compensated for by a self-alignment mechanism. Cartons are transported to an elevator via a first and second conveyor. The elevator lifts the cartons to the level of a palletizer with a false floor wherein a reciprocating and pivoting transfer head removes the cartons from the elevator and deposits them onto the prestacking area of the palletizer false floor. Cartons may be selectively rotated into a transverse loading position by the transfer heads. Upon assembly of a first row of cartons, a tamping bar extends to position the cartons against the truck tailgate or against previously stacked cartons.

  • Patent number: 4479347
    Abstract: A loading vehicle having a pick-up drum with resilient fingers for picking up straw material from the ground and a conveyor drum with conveyor arms, fitted in rows for carrying the material into the vehicle. The pick-up drum and the conveyor drum are disposed with respect to each other so that the conveying direction of the material is abruptly changed when the material is introduced into the path of motion of the conveyors. This produces a damming-up effect causing the material to be distributed over the entire conveyor front, which minimizes the tendency of squeezing between conveyors and the housing wall defining the conveyor duct at one side. The change in conveying direction also causes a certain compaction of the material, resulting in a better utilization of the available volume. The structure allows short spacing between the conveyor arms and closely spaced knives are positioned in the conveyor duct so that the blades of straw can be cut in small pieces which are suitable for ensilage.

The troughs open downwardly into two vibrating feeders. The feeders supply the materials through a funnel to a conveyor belt. The conveyor belt is mounted on a turntable and can rotate to either side of the vehicle so that the material can be spread at an adjustable distance from the tracks to either embankment located along the path of travel. The vibrating frequency of the feeders and the speed of the conveyor belt are adjustable according to the speed with which the vehicle is traversing the tracks. The feeders are so designed to permit doorless operation of the troughs for discharging the material.

The auger is adapted to convey the cement within the container along the length of the auger to an outlet opening adjacent the bottom of the container. A vertical conveyor carries the cement upwardly from the outlet opening to a third conveyor which carries the cement to the concrete mixer being serviced. Within the container below the auger conveyor are a plurality of fluffing means which introduce air under pressure to the cement to cause it to be fluffed and to prevent it from packing around the auger screw.
