Domestic mainly contains: the shower nozzle of developing among the Wang Yun in 1998, around the nozzle delivery port, be provided with square baffle plate, and the current of ejection are shaped to square, and nozzle structure is simple, belongs to fixed sprinkler; Calendar year 2001 Hao Pei already wait the people developed three kinds on impact driven sprinkler the hollow shaft place hole screening type flow control valve is set, by T shape hole with moving decide the periodic adjustment of the gap realization operating pressure at sprinkler between the valve to reach the cyclically-varying of range; People such as calendar year 2001 Feng Hao have developed flow-stopping sheet or the shutoff valve that installs definite shape at the shower nozzle water inlet additional.Install flow-stopping sheet additional and periodically change the area of its cross-section of river, and then change flow and range by the relative motion of sound sheet; Wu Pu top grade people in 2003 has invented by conical tooth wheel disc and angular wheel and has rotated, and makes blade relative shower nozzle rotation in nozzle the place ahead of installing on the angular wheel, and the length of blade difference periodically stretches into and withdraw from injection stream, and sprinkler pattern range is regulated automatically; People such as Korean thunderbolt invented a kind of cam disc of installing on the impact driven sprinkler pedestal in 2003, made the water screw that is installed in nozzle the place ahead move up and down broken water along with shower nozzle rotates by cam drive, to change sprinkler pattern range.
By retrieval, the patent of declaring that does not also have this variable-flow even insufflation showerhead structure at present.
Summary of the invention
Baroque deficiency at existing variable spray nozzle, for further improving the sprinkling irrigation quality, reduce the spray irrigation system cost, the purpose of this invention is to provide simple in structure, spray evenly, the change of function admirable sprays the territory even insufflation showerhead, reaches the purpose of water saving and economize on electricity.The present invention has characteristics simple in structure, with low cost.
The technical solution adopted for the present invention to solve the technical problems is: this shower nozzle is made up of fixed support, hollow shaft, the A that turns, the B that turns, driving mechanism.Driving mechanism can be a rocker-arm, also can be full jetting type.It is characterized in that: fixed support is made up of axle sleeve and guide rail, and the two is connected as a single entity.Guide rail is the smooth curve shape, and the shape that curve fluctuates up and down can design according to the sprinkling zone that shower nozzle requires to realize.Spray the zone and can be square, rectangle, triangle, ellipse.The A that turns adopts the joint form to be connected with the B that turns, and the hole cross section on the A that turns is for circular, and the hole cross section on the B that turns is a triangle or subtriangular.
During work, current spray along driving mechanism through hollow shaft, the A that turns, the B that turns.When current flow through driving mechanism, driving mechanism produced the driving force that makes the shower nozzle rotation.Driving mechanism drives the B that turns and rotates around central axis along support bracket fastened guide rail, turn B simultaneously and swing up and down with respect to the joint part of the A that turns, the elevation angle of shower nozzle changes, the A that turns slides with the face of cylinder of the B joint portion of turning, the phase cross surface area in two holes changes on the face of cylinder, and the change of area has impelled the flow change.When the elevation angle increased, phase cross surface area increased, and capacity of sprinkler increases, and sprinkler pattern range increases; When the elevation angle reduced, phase cross surface area reduced, and capacity of sprinkler reduces, and sprinkler pattern range reduces.
Its advantage is because the change of turn the B elevation angle and capacity of sprinkler has impelled the variation of range, and flow was big when range was big, and range hour flow is little, and application rate of sprinkler irrigation is even so can realize the non-circular sprinkling zone, and whole nozzle structure is simple, sprinkling is even.
