Embodiment Construction

[0018] See attached Figure 4 , according to the technical scheme of the present invention, the double-variable accurate irrigation nozzle with synchronous controllable range and flow comprises a rocker-arm type nozzle 20, and the water-passing hole 1 (diameter is Φ) at the water inlet end of the rocker-arm type nozzle 20 hollow shaft 2 ) is changed from a circular cross-section to a non-circular water cross-section ( figure 1 ), the water passing hole 1 is integrated with the hollow shaft of the rocker-arm type sprinkler head. And between the hollow shaft of the original rocker-type shower head 20 and the water supply standpipe, a double-ended threaded pipe joint 5 ( figure 2 ); an annular support section 6 is provided between the two threads of the double-ended threaded pipe joint 5, and a through hole 7 is opened in the center of the annular support section 6, the diameter of which is the same as the outer diameter of the hollow shaft water passage hole 1 , there are two...

Abstract

The invention relates to a dual-variable accurate irrigate ejector whose jet range and flux can be synchronously controlled, wherein it comprises a swing ejector whose round section of inlet of hollow axle is changed into non-round section; one dual-head screw connector is arranged between the hollow axle and the water upright tube; the connector has one water baffle plate that moves up and down; when the ejector works, the relative motion between water baffle plate and water through hole can periodically change the water section, to change the pressure, flux and jet range, to synchronously control the spray area and spray amount, and improve the sealing property and control accuracy. The invention has simple structure, low weight and low cost.

Description

technical field [0001] The invention belongs to the field of mechanical parts manufacturing, and relates to a spray nozzle for irrigation of farmland, gardens and flower nurseries, and in particular to a double-variable precision irrigation nozzle with synchronous controllable range and flow. Background technique [0002] The core technology of precision irrigation is to be able to develop equipment that needs to irrigate different amounts of water at different locations according to the shape of the crop or plot. In addition to equipment equipped with Global Positioning System (GPS) and Geographic Information System (GIS) on the irrigation machine, it mainly includes Variable water application irrigation sprinklers, controllers and variable flow pumps. Among them, the most critical equipment should be variable water application precision irrigation sprinklers, which mainly have three types: one is a pulse sprinkler that controls the spraying time th...
