摘要:
A center pivot irrigation system including a framework, a fluid conduit supported by the framework, a plurality of fluid-emitting nozzles associated with the fluid conduit, and a central control panel. Further, the irrigation system has an offsite irrigation controller, including a fluid-pressure sensor for sensing the fluid pressure inside the fluid conduit and a digital compass for monitoring the orientation of the irrigation system as it rotates about the center pivot axis. The offsite irrigation controller also includes a remote transmitter for communicating to an offsite receiver and an electrical processing circuit coupled with the fluid-pressure sensor, the digital compass, and the remote transmitter. The electrical processing circuit receives an output signal from each of the fluid-pressure sensor and the digital compass, and controls the remote transmitter to transmit the operational status of the irrigation system to an offsite user.

Water is emitted directly onto the soil from drip lines pulled from a mobile drip irrigation device. The forward ends of the drip tubes are anchored and retained to establish relatively fixed intervals of spacing between the forward ends of the adjacent drip tubes to guide the drip tubes across the soil and through growing plants. A pressure-regulated constant-volume flow of water is emitted from ports in the drip tubes.

A device for irrigating soil has a chassis having wheels or tracks for motion, the chassis having one or more water sprinklers with streams directed at the soil, a water storage tank, and a sloped catchment surface having one or more sloped planes or curved surfaces for receiving water from a refill station into the water storage tank, wherein, under the control of an electronic circuit, the irrigation device can refill the water tank by positioning any part of the catchment surface under a water stream from the refill station. A method has the steps of measuring soil moisture at remote locations, refilling the mobile robot using a gravity feed water stream, defining a route for distribution of water, traversing the irrigation routes, refilling water according to soil moisture measurements, storing photovoltaic energy in a battery, and rotating, to a compass heading such that the photovoltaic array is optimally oriented.

A convenient, water-saving and labor-saving FROG irrigation controller and system are provided, which determine the appropriate water budget and schedule for the property's landscaping based on evapotranspiration data for the geographic area, regulation data (any mandated and voluntary watering restrictions), and property-specific data, with consideration given to reduction in watering days, increase in soil watering depth, and day of year. Once set, the FROG controller provides incremental adjustments over the course of the year; the homeowner no longer needs to re-set the watering program seasonally to comply with local mandated and voluntary watering restrictions. Compliance is automatic and obligatory, meeting the water saving goals of the local water authority. Optionally presented is a web-based wizard used to determine a customized water budget/schedule that is input into the FROG controller through a data storage unit or wireless input.

A sprinkler transferring apparatus is provided for a flexible sprinkler drop on an irrigation supply line. The sprinkler transferring apparatus includes a lifting tool and a sprinkler component support body. The lifting tool has an elongate body with a first contact portion and a handle spaced from the first contact portion. The sprinkler component support body has a second contact portion configured to mate with the first contact portion.

A crop sprayer includes a main frame. A product tank is supported by the main frame that is configured to contain a first quantity of fluid therein. A cab is supported by the main frame that includes a trailing wall structure positioned in relation to the product tank so as to define a reservoir space therebetween A hydraulic reservoir assembly is positioned in the reservoir space.
摘要:
In a sprayer nozzle apparatus a pressurized liquid source directs pressurized liquid through a supply conduit and a supply port connects the supply conduit to first and second nozzles oriented such that spray patterns dispensed thereby do not intersect. First and second pressure sensors send pressure signals to a controller indicating first and second operating pressures at the nozzles. First and second pressure regulators vary the corresponding operating pressures in response to a control signals received from the controller to vary the dispensing rate of the first and second nozzles.
摘要:
An agricultural field sprayer having a boom that can be mounted on a tractive unit such as a tractor is described. The boom is composed of plural sections that are pivotal relative to each other and is adapted to be pivoted from a transport position into a working position and/or back to the transport position. Components of the boom are made from fiber-reinforced composite.

A wheel assembly includes a collapsible wheel and an airless flexible tire mounted on the wheel. The wheel includes a central portion and a plurality of circumferentially spaced mounting elements attached to the central portion. Each of the mounting elements is movable between a retracted position and an extended position, and may be pivotally attached to the central portion of the wheel and configured to pivot between the retracted position and the extended position. The tire may be positioned on the wheel when one or more of the mounting elements is in the retracted position, and the one or more mounting elements are moved to the extended position wherein the mounting elements engage and support the tire.

A vehicle with devices thereon for exercising the valves of a municipal water system includes a first arm with a valve turning machine at its outer end. A second arm is also attached to the vehicle, the second arm having a torque multiplier head having an input end and an output. A connector connects the valve turning machine to the input and the output of the torque multiplier applies increased torque to the stem of a valve.
