Abstract
The utility model discloses a fan -type sprinkler head for fruit tree disease and pest control, including showerhead body, nozzle cap, the last liquid runner that is equipped with of showerhead body, showerhead body's upper portion is equipped with the nozzle, is equipped with first arch and first recess on the nozzle, nozzle cap and showerhead body threaded connection and with first protruding counterbalance of nozzle, be equipped with the orifice on the nozzle, the orifice includes tapering section and cylindrical section, the tapering section and the liquid runner of orifice communicate with each other, the cylindrical section and the first recess of orifice communicate with each other. The utility model discloses an effect is: setting up first recess through the orifice department at the nozzle, assault forming the blowout of fan -shaped form at first groove from orifice spun liquid medicine, so the shower nozzle spray angle of this scheme being big, liquid medicine coverage area is big, and the sprinkler structure of this scheme is simple, convenient to use.
Description
Technical field
This utility model relates to the shower nozzle of aerosol apparatus, is specially a kind of Fan spray head for pest and disease control of fruit trees.
Background technology
At present, the fruit tree in China's different regions plantation is all frequently subjected to the harm of various insect in growth course, brings very big impact to the normal growth of fruit tree.This situation is generally adopted to artificial physics preventing and treating and chemicals two kinds of methods of preventing and treating, artificial physics preventing and treating mainly includes receiving pupa, ties up grass handle, light trap, seizure adult, catches and kills mature larva etc., this kind of method is comparatively laborious, poor effect, chemical prevention generally by spraying machine by medicine liquid spray on fruit tree.
When spraying machine carries out medicine liquid spray, sprinkler performance quality will directly influence the prevention effect to fruit tree diseases and pests, and the shower nozzle ubiquity area coverage of currently used spraying machine is narrow, the inefficient problem of medicine liquid spray.
Utility model content
This utility model is intended to provide a kind of medicinal liquid area coverage that can increase to improve the Fan spray head for pest and disease control of fruit trees of medicine liquid spray efficiency.
The Fan spray head for pest and disease control of fruit trees in this programme, including sprayer body, sprinkler cap, sprayer body is provided with flow channel for liquids, the top of sprayer body is provided with nozzle, and nozzle is provided with first protruding and the first groove, and sprinkler cap is threadeded with sprayer body and offsets with the first projection of nozzle, nozzle is provided with spray orifice, spray orifice includes tapered section and cylindrical section, and the tapered section of spray orifice communicates with flow channel for liquids, and cylindrical section and first groove of spray orifice communicate.
The principle of this programme is: when carrying out the sprinkling of medicinal liquid, high pressure medicinal liquid enters the flow channel for liquids on sprayer body, and the tapered section of spray orifice is entered through feed liquor runner, when high pressure medicinal liquid is close to the cylindrical section of spray orifice, the radius of gyration of high pressure medicinal liquid reduces, peripheral speed becomes big, the direction of motion and orifice center line that the high pressure medicinal liquid now sprayed by the cylindrical section of spray orifice is actual have certain angle, this angle is the atomizing angle of shower nozzle, after the ejection of high pressure medicinal liquid blowing hole circle shell of column, impact is at the droplet of the first groove formation fan shape of nozzle, this droplet further hits against with the air of geo-stationary and forms less droplet, it is sprayed onto on crops.
The effect of this programme is: by arranging the first groove at the spray orifice of nozzle, impacting from the medicinal liquid of spray orifice ejection and form fan shape ejection at the first groove, therefore the shower nozzle spreading of spray of this programme is big, and medicinal liquid area coverage is big, and the nozzle structure of this programme is simple, easy to use.
Further, the tapered section of spray orifice is additionally provided with some annular grooves, and medicinal liquid constantly impacts with annular groove mutually at the tapered section of spray orifice, therefore when medicinal liquid sprays from the cylindrical section of spray orifice, medicinal liquid can form the droplet that diameter is less, so that medicinal liquid can better cover on fruit tree.
Further, being additionally provided with gasket seal between sprayer body and nozzle, gasket seal is mainly used in preventing medicinal liquid from leaking from the cooperation of sprayer body and nozzle.
Further, gasket seal is Viton gasket seal, Viton gasket seal not only good seal performance and also corrosion-resistant property is strong.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: sprayer body 1, flow channel for liquids 2, sprinkler cap 3, gasket seal 4, nozzle 5, spray orifice 6, cannelure the 7, first projection the 8, first groove 9.
Embodiment is substantially as shown in Figure 1: for the Fan spray head of pest and disease control of fruit trees, including sprayer body 1, the middle part of sprayer body 1 offers the flow channel for liquids 2 through sprayer body 1, it is further opened with screw thread at the cylindrical place of sprayer body 1, the screw thread of sprayer body 1 left end is connected with sprinkler cap 3, and the screw thread of sprayer body 1 right-hand member is connected with outside spray boom.
It is provided with gasket seal 4 in the left side of sprayer body 1, consider that the medicinal liquid for pest and disease control of fruit trees has corrosivity mostly, in order to ensure the reliably working of gasket seal 4, in the present embodiment, gasket seal 4 adopts Viton gasket seal, Viton gasket seal not only good seal performance but also corrosion-resistant property are strong, are further opened with through hole at the middle part of gasket seal 4.
It is additionally provided with nozzle 5 in the left side of gasket seal 4, the first projection 8 it is provided with on the right side of nozzle 5, medium position at nozzle 5 is provided with spray orifice 6, spray orifice 6 includes tapered section and cylindrical section, wherein the tapered section of spray orifice 6 is on the right side, cylindrical section is on a left side, and the tapered section on the right side of spray orifice 6 is communicated with flow channel for liquids 2 by the through hole of gasket seal 4, and the tapered section of spray orifice 6 is version left small and right large.
It is further opened with some cannelures 7 at the tapered section place of spray orifice 6, the present embodiment intermediate annular groove 7 from left to right has four respectively, cannelure 7 is mainly used in increasing the collision of medicinal liquid, make medicinal liquid can form the droplet of more minor diameter, the first groove 9 it is additionally provided with in the left side of spray orifice 6, first groove 9 communicates with the cylindrical section of spray orifice 6, is additionally provided with, with nozzle 5 joint, the circular arc chamfering preventing stress from concentrating at the first groove 9.
Being connected to sprinkler cap 3 at the thread segment place of sprayer body 1, threadeds with sprayer body 1 in the right side of sprinkler cap 3, and the first projection 8 of the left side of sprinkler cap 3 and nozzle 5 offsets, and sprinkler cap 3 is for carrying out position restriction to nozzle 5.
