As everyone knows, the atomising device of the widely used agricultural hand sprayer configuration in rural area is feed liquor formula shower nozzle radially, uses till today from the fifties, and structure is outmoded, pulverability is poor.No standard is sprayed in the field in addition, sprays extensively, causes the deposition ratio of soup on plant that is sprayed onto in the farmland low.Only have about 10% general seedling stage, and the middle and later periods also is no more than 50%, and most fluid loss, drift had not only been wasted agricultural chemicals, but also polluted environment in environment.Agricultural chemicals updates at present, and protection environment, science use agricultural chemicals more and more to be paid attention to by people.Dosage by every mu of past BHC and DDT epoch execute at every turn how many, several two, develop into present every mu and only execute tens milliliters or a few gram at every turn.Contradiction between new agricultural chemicals and extensive insecticide-applying way and the spraying equipment becomes increasingly conspicuous.From world's pesticide application technology, spraying equipment just towards meticulous, micro-, high concentration, the target direction is developed (" chemical prevention Research progress " P14-18, P58-59, Tu Yuqin chief editor, Xinjiang science and technology health publishing house, 1992).For science is used agricultural chemicals, is reduced agricultural chemicals loss drift, many in recent years Chinese scholars are furtherd investigate, controlled droplet application (CDA), biological optimum grain-diameter new theories such as (BODS) (Tu Yuqin: " slightly opinion China technique in using agriculture chemical develops and development " have successively been proposed, Scientia Agricultura Sinica, 1986, the 5th phase, P71).Carried out the research (Gao Liangrun " Electrostatic Ultra-Low-Volume Spraying Equipment commentary ", agricultural mechanical journal, 1979 the 10th the 1st phases of volume) of electrostatic spray technology and low amount, ultra low volume spray technology and sprayer unit.In order to improve the accuracy of spraying insecticide, developed countries has been used electronic computer control spray medicine on the tractor tractor-hitched sprayer.Limit in view of the Chinese countryside economic level, in quite over a long time, spray insecticide still based on hand sprayer.Abroad seldom, to hand sprayer research since the eighties China various places to the spray technique of hand sprayer and radially the feed liquor shower nozzle improve.As applying of technology such as small-bore spray sheet and high speed water whirling piece, these technology have played certain effect to raising technique in using agriculture chemical, minimizing fluid loss.But little spray nozzle sheet or high speed water whirling piece all reach reduction spray amount, (Shang Heyan, " hand sprayer low-gallonage spraying and application thereof ", nineteen eighty-two, Chemical Industry Press) by reducing injection diameter; And the high speed water whirling piece is for adding the structure of smart filter pocket, easily obstruction of spraying, easily crimp in the middle of the inside and outside annular groove.(hand sprayer " efficiently the research of abridged edition pesticide application technology is used " work summary, the exploitation of Jiangsu Province's pesticide application technology and application cooperative groups, 1991).They have only played the reduction discharge rate, and can not prevent and treat needs conversion atomize according to difference, i.e. conversion spray amount, spreading of spray, fogdrop diameter etc.

At the problems referred to above, carried out the research of accurate pesticide application technology and apparatus in recent years.By research soup mist bundle, droplet in field and crop clump, deposit, distribute, adhere to, the rule of drift, find out the effective way that the raising agricultural chemicals effectively utilized, improved prevention effect.Effective rate of utilization for implementation science use agricultural chemicals, raising agricultural chemicals reduces fluid loss, reduces environmental pollution, especially due to illness, worm, crop etc. are of a great variety, wanting during control can be according to the different requirement of controlling object, and the conversion spray parameters reaches best prevention effect with minimum dose; And, reduce the control cost in conjunction with the economic level in current rural area, and reduce farmer's burdens, through repetition test, the spy has proposed the utility model.

The utility model discloses the serial shower nozzle of a kind of fine mist simple in structure, that be convenient to application operating at the problem of last existence.Fine mist series shower nozzle is made up of with the radially feed liquor shower nozzle coupling of the different spray nozzle sheets of configuration newly-increased one group of fine fog plate.Fine fog plate is that a side has a plurality of flowing holes, opposite side has the spin slot of varying number, different size and the garden dish type tablet of spin chamber, the structure of spin slot quantity, size and spin chamber by changing fine fog plate changes spray characteristics, make fine mist series shower nozzle have spray characteristics such as discharge rate is adjustable, spreading of spray is adjustable, fogdrop diameter is adjustable, during use, the operator can be according to the control needs of different disease and pests, select the coupling of conversion fine fog plate and different spray nozzle sheets rapidly and easily, satisfy the control needs under the various conditions.

Fine mist series nozzle structure is simple, and low cost of manufacture is easy to promote, on feed liquor shower nozzle radially, only increase a small amount of part and can realize multiple spray pattern, and having satisfied can be according to the requirement of the control needs conversion spray characteristics of Different Crop, different sick worms.Use it and can save agricultural chemicals more than 30%, improve soup at the deposition ratio on the target more than 20%.Both saved agricultural chemicals, reduced environmental pollution, and can improve work efficiency again widely, reduce the control cost.

Accompanying drawing is the section of structure of fine mist series shower nozzle.

Fine mist series shower nozzle is by radially feed liquor sprinkler cap (6), sprayer body (7), different apertures spray nozzle sheets (5) are formed with one group of fine fog plate (2) coupling of increase.Fine fog plate (2) is that one group of one side has a plurality of flowing holes (1), and opposite side has the spin slot (3) of varying number, different size and the garden dish type tablet of spin chamber (4).During field conversion pulverability, sprinkler cap (6) is backed out from sprayer body (7) together with spray nozzle sheet (5) and fine fog plate (2), the fine fog plate of choosing (2) and spray nozzle sheet (5) sprinkler cap of packing into, fine fog plate is placed between spray nozzle sheet and the sprayer body, notice that a side that has spin slot and spin chamber relies on spray nozzle sheet, then sprinkler cap is screwed on the sprayer body together with spray nozzle sheet and fine fog plate, can finishes the process of conversion pulverability.Select fine fog plate and spray nozzle sheet to require according to the control of Different Crop, different sick worms to determine, with the control bollworm is example: when the control second-generation cotton bollworm, this moment, worm and ovum were concentrated harm cotton plant plunger tip position, can choose in the series No. 1 fine fog plate and join corresponding spray nozzle sheet, its spreading of spray is little, spray amount is few, make to be sprayed at cotton plant plunger tip portion in the mist constriction, can save agricultural chemicals, can improve preventive effect again; And prevent and treat three, four generations of cotton bollworm, worm distributed with ovum whole strain on cotton plant and endangered this moment, can choose 2 or No. 3 fine fog plates and join corresponding spray nozzle sheet, its spray amount is moderate, and droplet is thin, spreading of spray enlarges, and carries out complete stool swing spray medicine, spray and evenly economize medicine, can improve work efficiency again.In a word, on hand sprayer, ecological characteristic according to Different Crop, harm feature and its control requirement of different sick worms, choose corresponding fine fog plate and spray nozzle sheet coupling, the conversion atomize sprays, and not only can save agricultural chemicals, improves preventive effect, reduce the pollution of environment, and shorten the gap of China with external pesticide spraying advanced technology level greatly.
