摘要: A detachable frame of a light-small sprinkling machine for precise irrigation, which belongs to a key equipment in modern agricultural irrigation. The detachable frame of a light-small sprinkling machine for precise irrigation comprises angle steel pieces, tiepieces, support bars, support upright rods, top truss with slots, and wheels, wherein, the components of the frame are connected through threaded connections, so that the frame can be disassembled and removed easily. The distance between sprinkler heads and the mounting height of the sprinkler heads may be changed by means of free movement of turning hooks in the top truss with slots. The number of spans of the truss of the machine can be selected according to the topographic structure and can be changed by means of threaded holes in the two ends of the top truss with slots, and thereby the length of the truss can be changed. The irrigation sprinkling machine has high adaptability, and achieves even sprinkling distribution. The irrigation sprinkling machine is stable, light, easy to disassemble and remove, and solves the problems of poor mobility and material waste of light-small irrigation sprinkling machines in the prior art. Employing low-pressure sprinkler heads, the irrigation sprinkling machine achieves improved sprinkling evenness and saves power. Utilizing the turning effect of movable swivel shafts, the irrigation sprinkling machine can be turned to any direction freely, and thereby is more flexible.

摘要: An in-line button drip emitter may include a core fitting into a cover. For example, the core may include a cylindrical section with an elliptical cross section. For example the cover may close over a pressure reducing labyrinth formed in the outer cylindrical sides of the core. Optionally the cover has a long axis which is parallel to the long axis of the cross section of the core. In some embodiments, the bonding surface has an arched profile. Optionally, the arched profile fits an inner wall of an irrigation tube. For example, an axis of the arched profile may be parallel to the long axis of the elliptical cross section of the core and/or the arched profile may be parallel to the axis of the cover.

摘要: An emitter (120) includes a flow path from a water intake path (221), which is for taking in irrigation liquid within a tube, to a recessed part (251). This flow path includes a recessed surface part (242) closed, without contact, by a film (300). A channel (243) that forms a reduced pressure flow path included in the above flow path is formed on the surface of the recessed surface part (242). If the film (300) is pressed by the pressure of the irrigation liquid in the tube (110) and adheres to the recessed surface part (242), the flow rate of the irrigation liquid inside the emitter (120) is controlled to an amount that can pass through the channel (243).

摘要: 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 movable member for compensating for fluctuations in supply line fluid pressure. In one form the movable member includes a tapered baffle section movable between a first position wherein fluid is allowed to flow over the tapered baffle section and a second position wherein fluid is prevented from flowing over at least a portion of the tapered baffle section and the tapered baffle section effectively lengthening the extent of a pressure reduction passage. In another form, first and second movable members are provided for compensating for such pressure fluctuations. In another form, a plurality of inputs are provided which are movable between first and second positions to compensate for such pressure fluctuations.
