摘要:
A hopper spreader for installation on a vehicle has a flow regulator configured to regulate flow of particulate material from the container. The spreader has a conveyor mechanism for conveying particulate material to a spinner that distributes the particulate material to the surface over which the vehicle moves. The spreader also includes a flow regulation mechanism located between the particulate material in the hopper and the conveyor mechanism which is configured to regulate flow of material from the hopper to the conveyor mechanism.

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.

A road machine for preventing slippery roads and comprising a means for discharging and spreading material for preventing slippery roads as well as a device for verifying the discharge function. The verifying device comprises a microwave transmitter/receiver (10) and a signal processing circuit (20), which in response to the received signal can detect the presence of discharged material for preventing slippery roads. In this manner it is possible to carry out a contact-free verification of the discharge function of particles moving at a specific speed and in a specific direction.

Systems and methods for applying roadway surface treatments. The system has an aggregate application assembly and a resin application assembly that are mounted or otherwise secured to a truck or other vehicle. The resin application assembly is spaced from the aggregate application assembly in the direction of travel of the vehicle. As the vehicle moves along a roadway surface, the resin and aggregate can be continuously applied such that the aggregate is provided to portions of the roadway surface that have been covered with resin.

A system and method for the application of friction-modifying coatings to roadways, walkways, pathways and other areas subject to vehicular, human or animal traffic, the system and method comprising the controlled, simultaneous application of binder and filler to a surface of a substrate, using a mobile device which passes over the substrate as the binder and filler are being applied. The system includes a frame coupled to a vehicle. A spray bar is mounted on the frame and includes an array of spray nozzles coupled to a resin container. An air knife is mounted on the frame and coupled to an air compressor for generating an air curtain. An aggregate dispenser bar including at least one aggregate dispenser is coupled to an aggregate bin and mounted on the frame for dispensing aggregate.

摘要:
A mobile fiber dispenser that dispenses a variety of types and lengths of pre-cut fibers. The main body of the dispenser is a cylindrical hopper. The pre-cut fibers are loaded into the top of the hopper. Inside the body of the dispenser is a counter auger that keeps the fibers from bridging and clumping. As the fibers pass through the counter auger, they drop into a feed auger that pushes the fibers through an auger housing toward a declumping apparatus. The counter auger and feed auger rotate in the same direction. The declumping apparatus at the end of the auger housing and feed auger intercepts the fibers as the fibers exit the auger housing. The declumping apparatus provides an even distribution of the pre-cut fiber through a discharge chute that extends downward from the auger housing. The fibers are discharged into a field vehicle's mixing process or other collection apparatus.

A spreader assembly may include a hopper, an auger mechanism, a torque sensor that provides a signal based on a condition of the auger mechanism and, a controller that receives the signal from the torque sensor and determines a fill status of the hopper based on the signal from the torque sensor.

A method for calculating the change in mass over time of a storage area holding a load, while components of the load are being removed or added, and while the storage area is subjected to changing vertical acceleration, is disclosed. The method uses a computer to compare the measured weight of a load with a known mass to the measured weight of the variable load and calculated the mass of the variable load. Periodic measurements and calculations allow the change of the variable load over time to be determined. Controls influencing the addition and removal of load components maybe controlled in response to the calculated change in mass to maintain targeted rates of change.
