摘要： A center-pivot irrigation system having mobile towers interconnected by spans actuatable about a center-pivot, constant speed motors for each of the mobile towers, and variable gear ratio transmissions each driven by one of the constant speed motors and each driving one of the mobile towers. The irrigation system may also include a control system sending command signals to the variable gear ratio transmissions, independently increasing or decreasing a speed of the mobile towers via the variable gear ratio transmissions. The irrigation system may also include a sensors for providing alignment information regarding the spans to the control system. The control system may independently command the transmissions to speed up or slow down one of the mobile towers relative to alignment information received from the sensors.

摘要： An irrigation system includes a central pivot and a series of mobile towers connected to the central pivot and to one another by support structure. Each mobile tower has wheels and a motor for driving at least one of the wheels. A control system operates the motors to maintain alignment of the mobile towers and the central pivot while preventing power usage of the system from exceeding a maximum power threshold. The control system determines in which sequence to operate the motors to maintain alignment of the mobile towers while operating no more than a selected number of the motors simultaneously.

摘要： What is disclosed is a wheel, typically for use in conjunction with an agricultural irrigation system such as a pivot or wheel line. The wheel has a disc shaped body having a hub to attach to an external frame. The wheel has a plurality of feet attached to the circumference of the body. The feet are generally channel shaped having two ends at either end of the channel. The feet are positioned at the circumference of the body either on the circumference or in indentations or grooves on the circumference such that the ends of the feet overhang the body. Preferably the feet have a space, opening or void between the feet to allow for the passage of snow, mud or other material.

摘要： The central-pivot sprinkler contains a central-pivot sprinkler and a controllable variable spray gun. The controllable variable spray gun has a spray gun main body (2), a booster pump (7), and a spray gun connecting pipe (16). A water inlet of the booster pump (7) is communicated with a sprinkler pipe (15) of the central-pivot sprinkler. A water outlet of the booster pump (7) is connected to a water inlet of the spray gun main body (2) by means of the spray gun connecting pipe (16). The forepart of the spray gun main body (2) is provided with a spray nozzle (12). The tail portion of the spray gun main body (2) can be mounted at the end of a crossing-body (1) of the central-pivot sprinkler by means of a spray gun horizontal-rotation mechanism.

摘要： A rotational speed control device maintains a shaft rotation speed. The device includes a housing containing a viscous fluid and a shaft disposed in the housing and rotatable relative to the housing. A rotor is coupled with the shaft for rotation in the viscous fluid. The rotor is axially displaceable along the shaft between a low-shear position and a high-shear position. A spring mechanism is disposed in the housing and biases the rotor toward the low-shear position. The rotor may be designed to cooperate with the housing or other nonrotating features within the housing to vary a shear gap according to the axial position of the rotor. The rotor, housing and spring mechanism can be designed to cooperate to create large changes in braking torque in response to small changes in shaft rotational speed. This allows the rotation speed to be controlled within a relatively narrow range.

摘要： A pipe liner for lining a fluid-carrying pipe, the pipe liner comprising an elongated flexible conduit and a flexible flange. The flexible conduit includes an outer wall forming an open-ended central channel for allowing fluids to be pumped therethrough. The flexible flange extends radially from one end of the elongated conduit and includes a number of fastener holes. The flexible conduit and the flexible flange are configured to be collapsed and pulled through the pipe such that the flexible flange can be connected to a rigid flange of the pipe via the fastener holes. The pipe liner is less prone to leak and is easier to transport and install.
