Abstract
The utility model discloses a spraying spray head with multiple heads, which is matched with a sprayer. The utility model is characterized in that a rotating flow guiding wheel (5) which is provided with a spiral flow guiding slot is arranged in a sprat head body; the center part of the rotating flow guiding wheel, which is close to the end surface of a nozzle, is provided with a convex surface; the edge of the rotating flow guiding wheel is provided with a weir base, the height of the weir base is close to the height of a convex top; a vortex chamber (7) is formed between the end surface of a shaft and the inner circular surface of a nozzle cap. The utility model has the advantages of good atomizing effect, small and uniform fog drips, large scattering amplitude, etc., and the utility model is used for the agriculture industry, the forest industry, and the fruit industry, agricultural chemicals or foliar fertilizer can be saved, and agricultural chemical residue can be reduced.
Description
The utility model relates to the shower nozzle that matches with sprayer, is applicable to more low viscous liquid spraying.
In the prior art, spraying nozzle single head, bull is arranged, a kind of low pressure spraying nozzle of single head is disclosed as ZL85202314, the liquid that its operation principle is roughly pressure is flowed through and is fixed in the guiding device of shower nozzle inside, enter vortex cavity and form eddy current, when liquid leaves nozzle from vortex cavity, anxious poly-minimizing of pressure, the result produces droplet.But a common shortcoming is arranged, because liquid enters vortex cavity through the guiding device of fixed-direction, eddy current is inhomogeneous, and the fluid pressure loss is bigger, so the droplet of ejection is big, inhomogeneous, scattering amplitude is little.
Task of the present utility model is to overcome the above-mentioned shortcoming that existing spraying nozzle exists, and provides a kind of atomizing even, and droplet is little, the bull spraying nozzle that scattering amplitude is big.
For solving above-mentioned task, solution of the present utility model is: the liquid guide flow spare of common bull spraying nozzle inside is made spiral fluted rotatable wheel the (5) under the effect of liquid stream that brings to few 2 symmetries, this centre of taking turns near the nozzle shaft end face is a convex surface, the outer has with protruding rises approaching weir platform, form vortex cavity (7) between the face of garden in this end face and the sprinkler cap, inducer (5) external diameter is slightly less than sprinkler cap (6) internal diameter, to guarantee that the liquid stream overwhelming majority enters vortex cavity (7) by helicla flute, form eddy current, liquid sprays and the formation droplet from the nozzle at eddy current center.
Ordinary circumstance, the spiral stream guidance groove of opening 2 symmetries on water conservancy diversion spinning roller (5) outer wall gets final product, and lift angle is 20-80 °, be preferably between 40-60 °, when guiding gutter entered vortex cavity so that liquid is flowed through, better driving wheel (5) rotation did not cause the bigger pressure loss simultaneously.
When liquid enters nozzle when ejection from vortex cavity (7), because the anxious poly-current formation droplet that can rapid scattering comes that reduces of pressure.As cap of spraying nozzle (6) nozzle exit is designed to platform, the platform outer is designed to the garden cylinder, and the cylinder outer is designed to the umbrella face, and the scattering droplet of ejection is at a high speed broken through repeatedly colliding, and forms more tiny droplet, scatters along the umbrella face at last.
Because the utility model has adopted the spraying nozzle of said structure, make atomization of liquid better effects if, the general spraying nozzle of droplet is tiny, even, and scattering amplitude is bigger.With supporting farming, forests and fruit industry spraying agricultural chemicals or the foliar fertilizer of being used for of sprayer, when reaching the effect same with common shower nozzle, can reduce the consumption of agricultural chemicals or foliage fertilizer more than 15%, owing to used agricultural chemicals or fertilizer less, be worth so have considerable economic and society generalization, when especially spraying agricultural chemicals, can reduce residues of pesticides, reduced the environmental pollution that therefore causes, so also have environment protection significance.
Below in conjunction with accompanying drawing the utility model is described further.Fig. 1 looks installation diagram for the spraying nozzle axle.Fig. 2 is an A-A line cutaway view among Fig. 1.Figure center tap (1), distributing pipe (2), nozzle boss (3) connect as one, and joint (1) can flexibly connect with the sprayer connecting rod.Packing ring (4) is soft as rubber ring, seals.Inducer (5) can be pulled down, and cap of spraying nozzle (6) flexibly connects with nozzle boss (3).
The bull spraying nozzle of forming with 5 single shower nozzles is an example, sees accompanying drawing 1, and joint (1), distributing pipe (2) are welded as a whole with the available common metal material of nozzle boss (3) such as the copper of 5 symmetrical distributions.Packing ring (4) adopts the ordinary rubber circle, and inducer (5) adopts metallic copper or plastics, and spray cap (6) and nozzle boss (3) are with being threaded.For increasing the cosmetic look of material hardness and product, whole shower nozzle appearance electrodepositable.The lift angle that the last spiral stream guidance groove of inducer (5) is 2 symmetries is 45 ° a semi-round groove.This is taken turns by jet expansion one end face, protruding garden face is made in the centre, 60 ° of oblique weir platforms are made in the outer, platform height and middle cardiac prominence are risen approaching, so that form vortex cavity (7), another axle head of spinning roller (5) can be made an elongated garden post, and diameter is littler than the endoporus of nozzle carrier (3), when wheel (5) rotation, play guiding, balanced action.
Claims (4)
1, a kind of bull spraying nozzle, by the joint (1) that can be connected with the sprayer connecting rod, the distributing pipe (2) that is connected with joint (1), going up a plurality of single mouth spraying nozzle that is symmetrically distributed at distributing pipe (2) constitutes, spraying nozzle is by cap of spraying nozzle (6), seal washer (4) forms by flexible connection with nozzle boss (3), it is characterized in that sprayer body contains the rotatable inducer (5) of band spiral stream guidance groove, wheel (5) is a convex surface near nozzle shaft end face middle part, the edge has with convex surface rises approaching weir platform, forms vortex cavity (7) between this end face and cap of spraying nozzle (6) inner headed face.
2, bull spraying nozzle as claimed in claim 1 is characterized in that it is 20-80 ° spiral stream guidance groove that described water conservancy diversion spinning roller (5) has the lift angle of 2 symmetries.
3, bull spraying nozzle as claimed in claim 1 is characterized in that described cap of spraying nozzle (6) top nozzle exit is a garden type platform, and the platform outer is the garden cylinder, and cylinder outer, garden is the umbrella face.
4, bull spraying nozzle as claimed in claim 2 is characterized in that 40-60 ° of described spiral stream guidance groove lift angle.
