  • Patent number: 7789217
    Abstract: A device for eliminating fugitive material dust emanating from material being transferred from an upper conveyor, feeder or crusher to a lower position, or other location. The device allows adjustability of the chute's total flow capacity where increased capacity is required. The device has a sliding gate disposed in the hopper to control the rate of transfer of the material from the hopper. A chute is disposed below the hopper and is movable in both a lateral direction (transverse to the direction of belt travel), and movable in the axis of belt travel. A choke is slidably attached to the chute, and slidable therein. The gate is positioned to maintain a level of material in the hopper to prevent dust from emanating out of the hopper from the chute. The choke is positioned to reduce airflow through the material as it passes through the chute to a lower position.

  • Patent number: 5772004
    Abstract: A method and apparatus for loading a bin with articles such as fruit is provided. The apparatus has a filling conveyor pivotable between a position within the bin to he filled and the top of the bin. The discharge end of the filling conveyor is maintained at an offset distance from the contents of the bin. The filling conveyor carries a plurality of resilient flaps pivotally mounted at one end thereof to the filling conveyor for movement therewith. The flaps successively carry rows of the articles along an upper run from a take-up end to a discharge end, at which end the articles are dropped off of the flap. A second flap, moving along a lower run in a direction opposite to the upper run, gently catches the dropped articles, and deposits the articles in the bin. Subsequent flaps moving along the lower run then sweep the deposited articles away from the drop location and toward to other end of the bin, allowing the articles to pile up at that end.

    Abstract: An apparatus and method for processing a food product. A series of processing cabinets are each provided with an inlet and an outlet in one of the cabinet side walls adjacent an end wall. The product is carried by a series of individual product carriers, which are capable of turning relative to the rail. The carriers pass through the cabinet inlets, and are turned relative to the rail thereafter so as to pass through the cabinets in a closely packed arrangement. As the carriers approach the opposite end wall of the cabinet, the carriers are again turned so as to exit the cabinet in a direction perpendicular to the longitudinal axis of the cabinet.

  • Patent number: 4921089
    Abstract: A conveyor is used in combination with a supply of bulk material having an outlet of a predetermined relatively great transverse width to move the material from the outlet to an output location longitudinally and horizontally offset from the outlet in a transport direction. This conveyor has a trough itself having an intake of generally the large transverse width and opening upward at the outlet of the supply for receiving bulk material therefrom, a base extending in the direction, and a pair of side walls extending upward from the base and also extending in the direction. The side walls flare upward away from each other at least at the intake and have upper edges spaced transversely apart at the intake by the transverse width and lower edges spaced transversely apart generally along the full length of the trough by a relatively small transverse width.

  • Patent number: 4512705
    Abstract: A horizontal plow system method and apparatus has been developed for the homogenous blending and reclaiming of bulk solid particulate matter, such as coal, at a utility plant. The horizontal plow system apparatus comprises one or more displacement assemblies, each further comprising a receiving stationary top plate and a horizontal flight subassembly. Coal is deposited via gravitational forces from an elongated slot bin storage onto the receiving stationary top plate and is then pushed on a bias and ultimately displaced by angular flights during travel of the horizontal flight subassembly along the receiving stationary top plate. Operation of the displacement assembly serves to displace the bulk solid from the sides of the receiving stationary top plate such that portions of coal from along the entire length of the elongated slot bin storage are continuously and simultaneously falling onto a moving transfer belt below, thereby insuring a more even blending of the coal.

  • Patent number: 4312442
    Abstract: A scraper-chain conveyor has a scraper assembly and plurality of channel sections defining upper and lower runs for the scraper assembly. The scraper assembly passes round sprocket drums positioned at the ends of the conveyor, and is constituted by two drive chains and a plurality of scrapers connected thereto. The conveyor has first and second straight portions joined by a curved portion. The upper run of the curved conveyor portion is at a lower level than the upper run of the adjacent end of the first straight conveyor portion. The scraper assembly passes between the upper runs of said end of the first straight conveyor portion and the curved conveyor portion via upper and lower deflector rollers which direct the scraper assembly in a Z-shaped path. The upper deflector roller is provided with a drive, whereby the chain tension of the scraper assembly is negligible when the assembly passes round the curved portion.
