  • Patent number: 8528936
    Abstract: A system and method to reduce water spray from one or more truck tires of a truck driving through rain on a water covered road. A combination centrifuge and air compressor device collects a mixture of air and rainwater, to separate the air from the rainwater and to compress the air. An air distribution manifold system directs the compressed air from the combination centrifuge and air compressor device onto an area of the water covered road in front of one or more of the truck's tires so that the water from the area rises up from the road. Then a shield barrier channels the water that rises up from the area on the road away from one or more of the truck's tires.

  • Publication number: 20120053776
    Abstract: The present disclosure is generally directed to an adjustable speed irrigation system having a control panel, at least one water conduit, at least one tower, and a position sensor. A user inputs a user-defined end destination at the user-defined arrival time into the control panel. The control panel receives a current position of the irrigation system from the position sensor. The control panel compares the current position to the user-defined end destination and calculates a new optimum ground speed required to reach the user-defined end destination at the user-defined time based on the current position of the irrigation system. The control panel then sends a signal to a speed control unit to adjust the speed of the irrigation system to match the new optimum ground speed.

  • Publication number: 20100148570
    Abstract: A self propelled irrigation system has a drive tower on which a drive wheel is mounted to a rotating member of a drive mechanism with an axis of the wheel obliquely angled relative to a drive axis of the rotating member such that the wheel is tilted out of a plane normal to the drive axis. A hub has its oppositely facing sides arranged to support the wheel in such an orientation, and may therefore be mounted between the drive mechanism and wheel of a conventional irrigation system in which the wheel and drive axes were previously coincident. The tilt of the wheel causes an intentional wobble under rotation of the hub so that the wheel's point of engagement with the ground wanders back and forth during repeated passage of the drive tower over a particular path, thereby reducing a rut forming or deepening tendency of the irrigation system.

    Abstract: Mobile towers of an irrigation system have drive wheel assemblies that propel the towers along the ground. At least certain of the wheel assemblies may comprise dual wheels that share a common axis of rotation but are separately driven by their own drive motor. By driving the two separate wheels in unison but with their own individual drive shafts, increased ground-engaging surface area can be obtained without a consequential increase in load for any one motor.

  • Patent number: 6604697
    Abstract: A self propelled sprinkler is disclosed. The sprinkler has a support body with a drive unit which drives two rear wheels. The drive unit is powered by water pressure supplied through a hose which is coupled to the drive unit via a hose coupler. The drive unit has a cylindrical drive chamber with circular impeller in fluid communication with the hose coupler. The impeller is rotated by the water pressure and is mechanically connected to a lateral shaft. The shaft is connected to the rear wheels. Reduction gearing from the impeller to the shaft governs the speed of the sprinkler. The reduction gearing is achieved through a series of sun gears, carrier disks and planet gears. The drive unit also has an outlet which has a socket which allows the exit of the pressurized water. The socket allows the insertion of any variety of sprinkler heads. Thus, the sprinkler allows a variety of water distribution patterns. The sprinkler is propelled by water pressure rotating the impeller and eventually the rear wheels.

  • Patent number: 4664316
    Abstract: A linear irrigation system has the wheels on each end angled outward to stretch the entire pipe. Some of the vehicles in the middle of the pipe are steered responsive to the distance the elongated pipe is from a guide line. Steering is controlled by the movement of a cable. Bridges upon a tube on the cable are used to activate a microswitch. The microswitch itself is on a carriage which is responsive to the distance of the elongated pipe from a guide line. Therefore when any correction is needed, a predetermined correction is applied and no additional correction is applied until the carriage carrying the microswitch is again moved. The wheels are individually steered. The correction is almost instantaneous and is not dependent upon changing the angle of the entire moving pipe.
