Description
Technical field:
The present invention relates to it is agricultural it is spraying in carry the spraying nozzle of brattice effect, and in particular to be the anti-drift of taper wind field formula
Move spraying nozzle.
Background technique:
Pesticide drift is the important finger for causing the principal element of liquid waste and environmental pollution, and measuring spray effect quality
Mark.Relevant information shows that the loss 10% ~ 20% of yield, but in fact, sprinkling can be retrieved by implementing disease pest and weed prevention and treatment to crops
The only few part of the pesticide gone out can reach on the target to be prevented and treated.Foreign scholar did estimation, sprayed from spraying equipment
The insecticide gone out only 25% ~ 50% can be deposited on crop leaf, and wherein the medicament less than 1% can be deposited on target pest,
And the pharmaceutical quantities of insecticidal action can be really played less than 0.03%.
China is one of pesticide producing amount and the maximum country of usage amount in the world, and national Pesticide use amount amounts within 2009
1280000 tons.Since the spraying equipment and pesticide application technology in current China also fall behind relatively, mainly lacked existing for traditional spraying system
Point is exactly that drift phenomenon is serious, and 70% ~ 80% pesticide applied is lost in the ambient enviroments such as air, soil, water system, is wasted
A large amount of pesticides, cause sensitive crop phytotoxicity, person poultry poisoning, environmental pollution, reduce the work of agricultural application to a certain extent
Quality.The person poultry poisoning that China generates by pesticide and medical instruments improper use every year is up to tens of thousands of person-times, and wherein has suitable one
Part is caused by " drift poisoning ".Therefore, because the reason of economy, environment and safety, it is desirable that spraying system has preferable
Anti- drift performance, its drift value is reduced to bottom line.
The influence for reducing extraneous wind field, improves operation quality, to reach the mesh for reducing droplet drift, increasing deposition
's.
Summary of the invention:
The object of the present invention is to provide the anti-drift spraying nozzle of taper wind field formula, this anti-drift spraying nozzle of taper wind field formula is used
In solve presently, there are extraneous wind field to droplet drift effect the problems such as.
The technical solution adopted by the present invention to solve the technical problems is: this anti-drift spraying nozzle packet of taper wind field formula
Sprinkler body, nozzle are included, nozzle includes connector, inner casing, shell, nozzle core, and outer cover suit is between inner casing and shell outside inner casing
Conical flow interlayer, the lower end of conical flow interlayer extend out to form diffusion spout, and arc wind chamber, taper gas are arranged on the outside of connector
Stream interlayer is communicated with arc wind chamber, and arc wind chamber is connect with blast pipe, inner casing inner nozzle core, nozzle core lower part connecting spray nozzle, spray
Pipe lower end connects fan-shaped spout, and nozzle is connect by sprinkler body with drug-feeding tube, and sprinkler body is connect with nozzle by connector, sprinkler body lower end
It is sitting in card slot.
Connector has arc card hole in above scheme, and sprinkler body outer wall has arc convex, when sprinkler body is sitting in card slot, arc
Protrusion is inserted in arc card hole, and sprinkler body is made more securely to link together with connector, easy to disassemble.
Sprinkler body is installed on bimetallic tube in above scheme, and bimetallic tube is made of outside inner tube outer tube sleeve, and inner tube is into medicine
Pipe, the annular space between inner tube and outer tube is air intake passage, and air intake passage is connect with blast pipe by hose；Air intake passage is logical
Air hose connection windbag is crossed, windbag connects blower.
Two arc wind chambers are set on the outside of connector in above scheme, and two arc wind chambers are symmetrical arranged.
The invention has the following advantages:
1, of the invention since conical flow interlayer internal diameter is gradually reduced from up to down, gas has when declining in conical flow interlayer
Certain acceleration will form a taper wind field after gas goes out conical flow interlayer, and taper wind field sprays fan-shaped spout
Medical fluid be centered around in, which can keep out natural wind field to a certain extent is blown on taper wind field when natural wind is blown,
Taper wind field plays a protective role to medical fluid droplet, protects medical fluid droplet not blown by natural wind, reduces because of natural wind
The drift of droplet caused by, the influence of the extraneous wind field of reduction, improves operation quality, reduces droplet drift, increase to reach
The purpose of deposition.
2, for the present invention under the action of taper wind field, the kinetic energy of droplet has certain increase, is conducive to penetrating for droplet,
And in the droplet on wind field boundary due to colliding with air curtain, motion profile changes, and is conducive to mist droplet deposition.

Specific embodiment
Following further describes the present invention with reference to the drawings:
In conjunction with shown in Fig. 1-Fig. 4, this anti-drift spraying nozzle of taper wind field formula includes sprinkler body 1, nozzle 2, and nozzle 2 includes connection
First 3, inner casing 4, shell 5, nozzle core 6, shell 5 are sleeved on outside inner casing 4, and inner casing 4 is identical as 5 shape of shell, be it is pyramidal,
Lower end has flared edges, is conical flow interlayer 7 between inner casing 4 and shell 5, the lower end of conical flow interlayer 7 extends out shape
At diffusion spout, two arc wind chambers 8 are set on the outside of connector 3, two arc wind chambers 8 are symmetrical arranged, conical flow interlayer 7 with
Arc wind chamber 8 communicates, and arc wind chamber 8 is connect with blast pipe 9, there is nozzle core 6,6 lower part connecting spray nozzle of nozzle core, spray in inner casing 4
Pipe lower end connects fan-shaped spout 10, and nozzle 2 is communicated with sprinkler body 1, and sprinkler body 1 connects drug-feeding tube 14, and sprinkler body 1 passes through with nozzle 2 to be connect
First 3 connection, 1 lower end of sprinkler body are sitting in card slot 11, and connector 3 has arc card hole 12, and 1 outer wall of sprinkler body has arc convex 13, are sprayed
When body 1 is sitting in card slot 11, arc convex 13 is inserted in arc card hole 12, and sprinkler body 1 and connector 3 is made more securely to be connected to one
It rises, easy to disassemble, sprinkler body 1 is not modified sprinkler body using the sprinkler body used on existing agrosprayer, the present invention, but
Nozzle 2 is changed to the nozzle with conical flow interlayer 7.
When the invention works, sprinkler body 1 is installed on bimetallic tube, bimetallic tube is made of outside inner tube outer tube sleeve, inner tube
For drug-feeding tube 14, drug-feeding tube 14 connects sprinkler body 1, and the annular space between inner tube and outer tube is air intake passage 15, air intake passage 15
It is connect with blast pipe 9 by hose；Air intake passage 15 connects windbag 16 by air hose 17, and windbag 16 connects blower.
When work, the wind that blower generates enters among the conical flow interlayer 7 on the outside of spray head via air supply tube, due to taper
The exhaust vent of 7 bottom of air-flow interlayer is smaller, and gas has certain acceleration in conical flow interlayer 7, when gas goes out taper gas
After flowing interlayer 7, a taper wind field will form, which can keep out natural wind field to a certain extent, reduce because of natural wind
The drift of droplet caused by.And under the action of taper wind field, the kinetic energy of droplet has certain increase, is conducive to droplet
Penetrate, and in the droplet on wind field boundary due to colliding with air curtain, motion profile changes, and it is heavy to be conducive to droplet
Product.
Medical fluid provides power by water pump, and by medical fluid in from water tank extracting to drug-feeding tube 14, medical fluid is transmitted to spray through sprinkler body 1
Mouth 2 is sprayed by fan-shaped spout 10, is finally completed spraying operation.
