  • Publication number: 20130094904
    Abstract: A hopper for transportation of mineral or aggregates which prevents the material from falling off due to movements or slope, and which improves load performance and facilitates the download. In the joining areas between the front and the floor and between the sides and the floor there are folded or cylindered pieces giving curvature to such joining points, thus adding anti-adherent features to this hopper. The front is folded with a wide radius, also achieving an anti-adherent feature. There are also folds in the front and the shield to avoid beams in those areas of the hopper, thus decreasing the total weight of such hopper and reducing the appearance of cracks and lessening the amount of welding. Additionally, the area of release is wider than the front and shield portions to allow for a better sliding of the material during unloading.

  • Patent number: 8393824
    Abstract: An adjustable spacer plate 12 mounts over the US standard screed box 10 thermoplastic opening 14 of 0.125? and creates a 0.090? opening.[This eliminates the need for the user to buy another costly screed box.] For screeding over stencils, the spacer 12 can be flipped to create a zero clearance opening. This allows the thermoplastic to come out only when an opening in the stencil pattern is present. Also, as the die 14 wears down, the spacer can be removed which lets the standard size opening be used as a substitute for the 0.090? opening.

  • Patent number: 8376654
    Abstract: A vehicle mounted patching system for patching potholes and the like and incorporating method and apparatus for removing and flushing asphalt emulsion from the feed lines of the patcher which completely recycles the cleaning agent used to flush the feed lines, as well as eliminating any external discharge of potentially toxic materials. A cleaning agent is used to flush the feed lines. The emulsion is collected in a recovery tank and combined with fresh emulsion delivered from a storage tank when the collected emulsion reaches a given concentration. Electrical controls for operating both motors from a single power source employ arrays of cam-operated switches and a diode array polarized to prevent feedback of power from the power source to assure precision positioning of the multi-position valves to perform a given operation.

  • Publication number: 20130017017
    Abstract: An aggregate-spreading device is disclosed for widening roads, filling trenches, spreading any kind of road construction material, and creating shoulders on the side of roads at a controllable, quick, and steady pace. The aggregate-spreading device may be controlled by electronic motors and electronic actuators. The aggregate-spreading device is equipped with a skeletal frame, either a first and a second adjustable spreader assembly attached on opposing ends of the skeletal frame, or a single spreader assembly for allowing an operator precise control over placement of an aggregate. The aggregate may be supplied to the first or second adjustable spreader assemblies by adjusting the rotation of a reversible conveyor system. The skeletal frame simplifies manufacturing of the aggregate-spreading device and allows for easy repairs and maintenance. The electronic motors and electronic actuators eliminate the need for hydraulics, allowing an operator to control the device from a remote location with a controller.

  • Patent number: 8308394
    Abstract: Embodiments of the present invention relate to systems and methods implemented in a pothole patching system for creating a vacuum that pulls heavy particulate, such as gravel, out of a hopper. For example, according to an embodiment, a vacuum body having a vacuum chamber formed therein is positioned proximate to an opening of the hopper. A moveable slide gate is provided between the vacuum chamber and the opening of the hopper. The slide gate moves between open and closed positions for permitting and blocking communication between the vacuum chamber and the hopper. A reduction nozzle is provided between an air source and the vacuum chamber. Forced air flows from the air source, through the reduction nozzle, and into the vacuum chamber. The reduction nozzle reduces the pressure of the forced air entering the vacuum chamber, and thereby creates a vacuum in the vacuum chamber. When the slide gate is in the open position, this vacuum pulls particulate from the hopper.

  • Patent number: 8282312
    Abstract: A method of operating machine system includes receiving expected material placement data for a paving machine and comparing the expected material placement data with actual material placement data. The method further includes outputting a signal based on the comparison, and commanding replenishing material from a supply machine to the second supply volume responsive to the signal. A paving control system for a paving system includes a computer readable memory configured to store expected material placement data, a receiver configured to receive actual material placement data and a data processor configured to output a control signal to a supply machine to controllably replenish material to an external material supply volume for the paving system in a manner responsive to comparing the expected material placement data with the actual material replacement data.

  • Publication number: 20120253612
    Abstract: A mobile pothole patching vehicle includes a chassis and front and rear support wheels for the chassis. A cab is mounted on the chassis as is a paving material storage hopper. A paving material dispensing mechanism is mounted on the chassis and is in communication with the hopper. A discharge chute is in communication with the dispensing mechanism. A boom mechanism includes a proximal end mounted on the chassis. A first swivel mechanism rotates the boom mechanism in relation to the chassis. A tamper plate is mounted on a distal end of the boom mechanism. The machine can patch potholes through the actions of a single operator who remains in the cab during the patching or repair process, thus enhancing the safety of the patching operation.
