  • Patent number: 7395919
    Abstract: An enclosed belt conveyor having a high strength take-up section that maintains proper belt alignment with the use of just two take-up screws, while still allowing for the take up section housing to be made of lighter weight, less expensive materials. The take-up section of the present invention can be installed at a head section or tail section of an enclosed belt conveyor. The take-up section of the present invention generally includes two support arms slidably mounted in guides that maintain the support arms in a straight orientation and two take-up screws that adjust the support arms within the guides while maintaining proper alignment of the take-up section without the necessity of separate leveling screws.

  • Patent number: 5803695
    Abstract: A grain distribution apparatus and method is disclosed for positive positional control of the providing distribution of grain among a plurality of receiving ducts. A housing contains a distribution spout rotated by a drive motor among discharge positions at each receiving duct. A control wheel connected to the spout rotates with the spout to a selected discharge position. The control wheel has a plurality of sensible code clusters and position proof windows, one of each for each discharge position. Each code cluster has a unique series of data digits and a series of sequencing digits adjacent the data digits. The data digits and sequencing digits are serially read by a sensor. The sensor is connected to a control processor for identifying the position of the spout. The control wheel is configured as a driven sprocket and is engaged by the upper portion of a double wide roller chain around the entire periphery of the control wheel.

  • Patent number: 5593019
    Abstract: A chain return support suitable for use in an en masse grain conveyor has a track with a pair of angle irons extending lengthwise in the interior of a trough and supported by horizontal cross members bridging two side walls of the trough. The angle irons have inwardly facing horizontal edge portions and vertical lower portions. A plastic slide is inserted between the angle irons and is engaged with the angular edge portions by way of grooves extending lengthwise on side surfaces of the plastic slide. Stops on the cross member contact the lower portions of the angle iron for proper positioning of the track. The plastic slide provides a low friction surface for supporting the chain return section.

  • Patent number: 4058199
    Abstract: A conveyor device particularly designed for the conveying of mass loads such as grains, powders and the like which may be termed semi-solids which device includes an extending housing having a substantially flat support bed with a conveying mechanism engaging the upper surface thereof for the conveying of material thereover and wherein the conveying elements are of a predetermined minimal height in comparison to the load or height of material in the conveyor which is to be conveyed and an intermediate discharge for the conveyor which is arranged on the support bed thereof which includes a pair of door members hinged at their respective ends and opening downwardly from their mating edge which doors extend the full width of the conveyor and which are interlinked for simultaneous opening and closing to provide in their closed condition a smooth surface continual with the support bed of the the conveyor and which provide when open, an opening without ledges or other areas in which material may lie or become lodge

  • Patent number: 3952864
    Abstract: A detector unit for mounting on conveyors for automatic shut off of the drive portion of the conveyor which includes a detection and control device attachable to the tail or idler sprocket of the conveyor such that if the tail sprocket is moved forwardly, the detector will trip a switching control mechanism to shut down the drive portion of the conveyor and further, if the chain should break, the detector is provided with an automatic return mechanism to trip the switching control mechanism to again shut down the drive portion of the conveyor. The detector basically includes a movable tail sprocket assembly having a first range of adjustable movement and having a detector arranged to move with the sprocket over the adjustable range of movement such that when the sprocket is shifted beyond this adjustable movement area the switching control mechanism will be tripped to shut off the driving portion of the conveyor.
