摘要:
The present invention discloses an embedded type, inverted-filtering and anti-clogged emitter and drip irrigation pipe (tape). The emitter comprises a first component and a second component which are mutually fixed, and a filter cloth sandwiched between the first component and the second component; the first component and/or the second component are provided with a diversion channel, the first part is also provided with a water outlet channel which is capable of exposing the filter cloth and enabling the filter cloth to communicate with a water outlet of a water pipe, the part around the water outlet channel is fixed with the inner wall of the water pipe, and the filter cloth sandwiched between the first component and the second component is a medium leading the diversion channel to the water outlet channel. The present invention has a simple structure, is convenient to manufacture, lay and install, is strong in controllability of flow rate of seepage water, is small, uniform and stable in discharging flow, is little in sensitivity to water pressure change, can prevent physical clogging and chemical and biological clogging, and is wide in application range.

An irrigation drip emitter, and methods relating to same, are provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. The emitter having at least one moveable member for compensating for fluctuations in supply line fluid pressure. In one form the emitter further includes a root growth inhibiting member for hindering roots from obstructing fluid flow through the emitter. In another form, the emitter includes an inlet protrusion so that fluid entering the emitter comes from a position closer to the central or center portion of the conduit in order to avoid larger obstructions that may be located near the periphery of the conduit. In another form, the emitter includes a carrier for assisting in mounting the emitter into conduit. In another form, more than one of the above features are present.

A drip irrigation emitter may be provided with a coupler for bonding to an inner surface of a conduit. The emitter may include for example a button flow restrictor. The coupler may optionally provide an outlet zone on the conduit surface that is large enough for automated perforation. Bonding the emitter to the surface of the conduit may have a minimal effect on the dimensions and/or properties of the conduit. A button drip irrigation emitter may optionally include a two part labyrinth. The labyrinth may for example be confined between a cylindrical surface and a cover and/or wind between intermeshing baffles on the cover and/or the surface.

A communicable drip irrigator including a housing formed with a fluid inlet for receiving irrigation fluid and a fluid outlet for emitting irrigation fluid, and a flow meter associated with the fluid inlet and/or the fluid outlet, configured for obtaining flow data. The irrigator also includes a communication unit associated with the flow meter and configured for providing to a controller, data regarding operation of the drip irrigator, the data including at least the flow data.

A filter for use with overhead sprinkler irrigation systems is disclosed. The filter includes a body, a removable screen, and a manually-actuated plunger adjacent the screen. A water hammer table is partitioned in the body and located above the plunger. The plunger is positioned for reciprocal movement through a debris outlet between an open, debris-discharging position, and a closed filtering position. The plunger defaults to the closed filtering position by pressurized water flowing through the body. The water is simultaneously filtered through the screen and passes out a clean water outlet while debris accumulates within the body. The plunger may be manually retracted to the open, debris-discharging position at any time, whereby accumulated debris is flushed out of the body through the debris outlet by residual water flowing therethrough.
摘要:
A trellis mounted system for irrigation and frost prevention is described. The irrigation system comprises a trellis, a first conduit coupled to the trellis, and a second conduit coupled to the trellis. The first conduit delivers a heated water stream to a nozzle that provides a heated water spray to an area surrounding the trellis. The second conduit provides drip irrigation to a ground area surrounding the trellis. The heated water supplied by the trellis mounted irrigation system prevents the development of damaging frost on agricultural plants.

An agricultural system includes an irrigation system, a mulch system including mulch material, and indicia disposed on the mulch material for indicating locations on the mulch material. The indicia include burial indicia, conduit warning indicia and plant spacing indicia. The planting spacing indicia are disposed in a triangular grid on the mulch system. The mulch material includes a hole for planting, a hole for a stake to pass there through, and a hole for a row cover support to pass there through. The irrigation system includes a drip irrigation conduit and a further conduit for transporting water to a further irrigation system. The irrigation system includes a fitting and a manifold for transporting water to the further conduit. At least a portion of the irrigation system is bonded to the mulch system, and at least a portion is enclosed and maintained in the vicinity of the mulch system by a sleeve.

A drip irrigation pipe includes a drip emitter and a flap that is formed in the pipe wall by first and second grooves. The first groove is longer than the second groove and the flap remains connected to the pipe wall at two bridges. A pivot region of the flap extends between the two bridges and the flap is adapted to twist about the pivot region as liquid exits the pipe at the flap.

The present system comprises, a MFC controller, emitter-lines that utilize non-drain technology on the emission devices and control valves for individual drip lines or groups of drip lines within an irrigation zone, along with a means to actuate the control valves by the controller. The MCF system utilizes a number of valves in an irrigation system to control either individual emitter-lines or groups of emitter-lines but does not control individual emitters. The present system has a programmable controller that has a number of stations, each of which controls a group of valves. Each station can be programmed for start time and duration that the station is actuated. Each station can be programmed independently from all the others allowing overlap or complimentary irrigation. The total input flow rate to the system remains nearly constant during a daily irrigation while the valve groups are cycling within the system.

A sprinkler elevating apparatus is provided for use on an irrigation device. The sprinkler elevating apparatus includes a sprinkler support body and a midline hose coupling body. The sprinkler support body is configured to support the sprinkler at an elevated position relative to the irrigation device. The midline hose coupling body is carried by the sprinkler support body. The midline hose coupling body has a contact portion configured to affix to a midline section of a flexible hose drop of the irrigation device. A method is also provided.
