  • Patent number: 10294045
    Abstract: In accordance with embodiments of the present disclosure, systems and methods for using containers of bulk material along with a bucket conveyor system, instead of a pneumatic transfer process, to move the bulk material from a transportation unit to a storage/delivery system are provided. A transportation unit may deliver one or more containers full of bulk material toward a fill hopper of the bucket conveyor system. The containers may be positioned proximate the fill hopper to release the bulk material directly into the fill hopper. The bucket conveyor may deliver the bulk material from the fill hopper into the storage/delivery system. Since the containers are maneuverable into a position to output bulk material directly into the fill hopper and without pneumatic transfer, the bucket conveyor system may enable a cleaner and more efficient bulk material transfer at the site.

  • Patent number: 6092668
    Abstract: A litter screening and separating machine including a storage compartment, a loader at one end of the storage compartment for picking up encrusted litter material from the floor of a chicken house, a conveyor including a pair of chains for moving the encrusted litter from the loader to the storage compartment. A baffle plate adjacent to and beneath the conveyor chain prevents contamination of the conveyor chain. Vibrator rollers adjacent the pair of chains for engagement with tabs on spaced links of each chain for vibrating the loading flights. Trap doors beneath the upper run of the conveyor may be opened to permit some of the material collected to fall back to the floor of the poultry house. One can regulate the amount of material thus recycled by independently opening and closing the trap doors.

  • Patent number: 6015039
    Abstract: A sorting apparatus and method operative to selectively discharge articles, such as parcels, from a tilted, gated conveyor to a desired output destination is disclosed. A powered roller is mounted along the top of the gates so that when a gate is lowered to discharge a parcel, the parcel engages the powered roller and is drawn off the conveyor. The gate can be raised before the parcel has completely left the conveyor. The conveyor can be constructed having a width narrower than the parcels.

  • Patent number: 5871078
    Abstract: An apparatus and method for depositing objects at separated locations on a movable belt. The device includes at least one channel through which objects enter the apparatus. A sensor measures separation between adjacent objects approaching the apparatus and a reject mechanism prevents object that are too close to adjacent objects from entering the apparatus. Each channel includes a plurality of gates disposed therein. These gates operate sequentially to incrementally move the objects individually through the channel towards the movable belt. A sensor locates empty spaces along the movable belt, into which the objects are deposited. The movable belt is usually part of a conveyor system and may be a slotted belt or a smooth belt.

  • Patent number: 5865592
    Abstract: A stone metering system for a railroad track maintenance vehicle providing improved accuracy in stone delivery. The system includes a surge hopper, a number of metering augers, and a corresponding number of splitters. The metering augers convey ballast stones from the surge hopper to the corresponding splitters, which divide the stones evenly between a number of blow tubes. The pitch of the auger screw flights is increased from the inlet end of the screw to "expand" the stone and reduce the production of fines. In addition, the diameter of the final screw flight is reduced at the outlet end of the auger to provide a consistent and even flow of stone into the splitters. The splitters are dynamically adjustable to provide even distribution between the blow tubes regardless of the cant to the rails. The desired amount of stone is delivered to the tubes by rotating the auger screw the number of full or partial revolutions associated with the amount.
