  • Patent number: 5324097
    Abstract: A conventional bottom dump truck includes doors which in a closed position are suspended underneath the bottom opening of the hopper of the trailer. The doors are opened outwardly and upwardly by pivotal action about an upper suspension point of each of the doors. The amount of movement of the door is limited by an abutment member mounted upon a vertical flange on the outside surface of the hopper bottom. The abutment member includes an abutment plate extending outwardly from the flange together with a bracket which has a slot slidable along the length of the flange and locatable at different points along the length of the flange by a pin passing through openings in the bracket and one of a plurality of openings in the flange. An elongate triangular body can be positioned between the doors during operation at minimum spacing so as to increase the angle of the surface of the doors beyond the angle of repose of the material to ensure complete discharge without hang up of the material on the doors.

  • Patent number: 5035564
    Abstract: A truck body has at least one vertical, longitudinal divider forming two compartments. Separate chutes are located on the top of the body, one communicating with each compartment so that one particular type of refuse (e.g., paper, aluminum cans and glass) may be dumped into a specific chute to fall by gravity into a compartment. The body may be tilted to shift all refuse to the rear. Each type refuse is discharged through a separate door at the rear. Bins are lifted vertically by hydraulic means to the top of the body and then tilted to dump into chutes. The bins are tucked under the body during transportation to reduce overall width. Further, the bins fan outward to facilitate loading. Wheeled carts filled with refuse may be hooked to the upper edges of the bins so that the carts and bins may be tilted at the upper end of their travel to dump into the chutes.

  • Patent number: 4611642
    Abstract: The present invention is directed to a bagging device for directing a flowable substance from a transport trailer to a flexible agricultural bag. The device includes a tunnel housing attached to the back of the trailer. The open end of the bag is held behind a ridge member and between the ridge member and a stretchable strap so as to resist release of bag until the bag on the ground has been filled. A tray beneath the housing supports the bottom portion of the bag to prevent it from stretching and ripping. A shield near the tires of the trailer prevent the bag from entangling in the tires. The device is especially appropriate for use with flowable commodities such as brewers grains and stillage by-product which rapidly deteriorate unless promptly stored in an air exchange-free enclosure.

  • Patent number: 4552653
    Abstract: A rear dump truck for transporting particulate material and simultaneously discharging and sieving the material. The rear dump truck includes a load box divided into a front section and a rear section by a partition dump door. The front section of the box forms a load chamber space for carrying the particulate material and the rear section forms a load chamber space including wire sieves for sieving purposes. To adjust the flow rate of the particulate material passing from the front section into the rear section through below the partition dump door upon the tilting up of the box, a stopper which is tiltable by a hydraulic jack is positioned just before the partition dump door. The particulate material is supplied in a suitable amount at a given time through the adjustment of the tilting of the stopper and passes onto the wire sieves. The material is sieved and the sieved particles are discharged through rear dump doors according to the particle sizes.
