2. Old way of insect control was to spray the agricultural chemical by approaching the crops with extended rubber hose of which spraying distance was 8~12m after attaching it to cultivator or tractor (price $380"1, 760).

In order to lessen the weight and cost of high pressure rubber hose, water path is very narrow, which causes the increased pipe friction loss, and delivery of pressure that is the main part of particle, is not very scientific.

It had piston pump with low energy efficiency, inside diameter of rubber hose was 13~16mm, outside diameter was 21~25mm, length was 120~200m, and long time moving weight was 47~117kg.

Old way of insect control has very bad for human body because of short distance spraying and very bad working condition, but new product provides 60 times faster working time. It is fast and accurate. People do not have to go into the rice field anymore with its 86116m spraying distance. It can be sprayed still at the ridgeway or rice paddy, and will be the frontier of mechanizing agriculture.

3. In Korea and Japan, rice field was made to be 100m long by plan to use tractor or farming mechanics for easy and handy farming.

According to statistics of FAOSTAT STATISTICS DATABASE in 1997, rice field area of countries around the world is 151, 762, 000ha, and rice field, made with 100m length, in Korea and Japan is 2, 998, 000ha, which is 1. 98%. Number

of agricultural tractor of countries around the world is 26, 334, 690. According to the statistics from Korean Ministry of Agriculture in 1998, total cultivated field is 1, 910, 081ha, and 35. 52%, which is 678, 321ha, is made with 100m length.

Besides 30% of outside block, and field possible for 50m spraying work, actual field made with 100m length is 24. 86% of 474, 825ha, which is 0. 31 % of total cultivated field around the world.

4. Though 100m air spraying sprayer (price $ 600, 000) is very effective with small spraying particles, but it is too light and loss of spraying is too much. It also needs many workers. Consumed gasoline costs more than produced rice, and machine itself is too expensive. Thus, rental cost of the machine is expensive. It is also very noisy, and damages crops, power and communication line, vinyl house, and trees like hurricane. It is difficult to manage one by one, and very difficult to use partially at the right time. It is impossible to spray to field that is not regulated. It can also be the source of insect damage by wind, and can not be used for fire extinguishing purpose in mountain, since it can not enter the mountain.

5. Spraying particle between spraying distance of 50~100m for mixed type of 100m water sprayer and 30m air sprayer (price $ 90, 000) is like hard rain. Its spraying amount, which is 5 ton/min, is too much and is 20 times more than necessary amount. Therefore, damage will be done, and agricultural chemical will costs more than produced rice.

Since spraying particles between spraying distance 50~100m are big, insects, virus, fungus, bacteria, etc., which can only be seen with microscope, will damage the rice field.

Also, machine is very expensive, management is difficult, and maintenance is difficult. So, it is not very effective when insects or diseases actually happens.

It also can not enter the fields that are not regulated. It is affected a lot by the wind, and evenly distributed spraying is difficult. Thus, it is impossible to be used for mountain fire.

Smaller the spraying particles are, less amount of agricultural chemical is

needed. According to the experiment, it can only spray diameter of less than 0. 3mm under 50m range. Final objective of agricultural chemical is to increase the production. Therefore, if invested amount is more than production, it could not be industrialized.

3) Disclosure of Invention This sprayer can achieve industrial development through technical innovation, improve the farming environment. Modernized sprayer will prevent agricultural chemical poisoning, minimize working hours, improve health of worker, utilize unwanted harmful waste. It can be used in vast area, and will improve the productivity of the land.

A heavy metal, cancerogenic substances are fatal to human body, and can cause a complication and shorten life. Conventional insect controlling method that uses cultivator can not prevent to absorb much agricultural chemical through nose during summer time, when breathing capacity is large and heavy hose needs to be moved for a long time. This new sprayer improves productivity with innovative spraying. It also improves working condition, and makes up for the insufficiency of labor. It can also be applied to putting out the fire and dealng with harmful waste, and small truck will be replacing cultivator. It helps modernize agriculture by preventing agricultural chemical poisoning, shortening the laboring hours, improving international competitive power, increasing national prosperity and increasing the production of provision. In order to achieve even distribution, it installed six ceramic spraying nozzles. It also installed intercepting valve at top and bottom to control current quantity and spraying distance, and it is made solidly to rotate up-and-down and left-and-right.

It is the world's first invented farming appliance that considered speciality of rice plant in watery field, scale of farmland, power of tractor, physical property of water and air resistance of many different sides.

It is a high speed centrifugal pump that connects to PTO axis of tractor. It has no machine trouble, has good durability, has no side effect of alien

substances and has high energy efficiency, compared to conventional piston pump type.

Agricultural chemical poisoning gets absorbed into lungs or skin by dispersed pressure, scattering, osmotic pressure, pH, ionization, temperature, moisture, cellular tissue, capillary vessel, etc. Absorbing surface of human alveolus is 70~150m2 and very big.

Rice is the life and main meal of 3, 500, 000, 000 people in 120 countries, especially Asian countries. Rice is eaten after removing rice hulls, so there is no agricultural chemical absorbed into body. And by adding poisonous waste to agricultural chemical, it protects environment as well. Environment is very close to human life. It contributes to wealth of human, basic rights and economic growth. Natural environment is the mother of mankind and ground of life. Every year, level of agricultural chemical is raising to increase productivity. If person who sprays the chemical, absorbs it, it is fatal. So, modernizing the spraying equipment is necessary. Spraying distance of particle increases upto pressure limit, but particle gets too small after pressure limit.

Thus, because of air resistance, spraying distance decreases. After the distance limit, it does not depend on pressure, it acts complexly by size of particle, which is weight of particle and spraying amount. Particle of over 0. 3mm in diameter is too heavy. Its kinetic energy of cohesion, acceleration, etc. is greater than adhesive power. It just falls to the ground and gets wasted. It is not very effective, and related directly to production decrease. Sprayed particle only gets spreaded 3 times of particle's diameter, when diameter of particle is less than 0. 3mm, which is the limit of adhesion by weight and speed. If lgal (3. 78543L) of agricultural chemical is sprayed per lacre (4046. 849mu), when diameter of water particle is 0. 01mm, 170, 000 of them gets attached per unit cm2.

When diameter of water particle is 0. 02mm, 22, 200 of them gets attached per unit cm2. When diameter of water particle is 0. 05mm, 14, 300 of them gets attached per unit cm2. When diameter of water particle is 0. 1mm, 178 of them gets attached per unit cm2. When diameter of water particle is 0. 2mm, 22 of

them gets attached per unit cm2. When diameter of water particle is 0. 3mm, 6. 6 of them gets attached per unit cm2. When diameter of water particle is 0. 5mm, 1. 4 of them gets attached per unit cm2. Since amount of agricultural chemical sprayed per field is limited, effects of chemical is related to the attached particles. Ideal mixing means even if spraying amount is increased, attached amount does not increase. It is the best to spray a little more than the time when increasing of effect is 0. Water gets vaporized shortly, so repeated spraying is possible, before vaporization takes place.

Men exhale average of 2500mL in a day, and inhale 10, 000Liter of air.

Absorbing surface of human lung is 70~150m2, and normally the capacity of lungs per day is 400~500cc. But, in case of old spraying operation, it becomes 3500~4500CC for grown men, and 2500~3500cc for women. Diameter of particle possible to be absorbed by lungs is less than 0. 01mm, and every agricultural chemical dissolved in water can be absorbed into human body through nose and lung. Absorption area of skin for grown men is 1. 6mu, and if amount of molecular weight is less than 1000, it gets absorbed into human body directly from skin. Dioxen from weed killer and insect killer, nicotine from cigarette, anesthetic, insulin absorbed by lung, hallucinogen, medicine, briquet gas, waste gas from factory and automobile, poisonous gas, bio-chemical weapon, tear gas, gas gun, etc. can be absorbed by lung like agricultural chemical. There are medicines absorbed by lung, such as 6-Agonist, Theophylline, Steroids, Cromolyn Sodium, Sympathomimetics, Anticholinergics, Corticosteroid, etc.

Beauty product, cucumber massage, PAS, nausea treatment, medicine, arthritis treatment, pain killer, anesthetics, skin cream, eye water, erection promoting medicine, poisonous gas, bio-chemical weapon, tear gas, gas gun, etc., which can be absorbed through skin, are used industrially.

Particles of agricultural chemical are absorbed in three phase that is liquid, vapor, and solid. Potassium cyanide is 1, 000 times more poisonous than cigarette smoke, but dioxen in weed killer and insect killer (same as defoliant used in Vietnam War) is 1, 000 times stronger than potassium cyanide.

Carbon monoxide, such as briquet gas, reacts with hemoglobin 200 times faster than oxygen, and kills a person with oxygen shortage.

Stronger agricultural chemical is, easier to kill germs and insects, and more prosperous harvest. But, it is fatal economically and to human body.

Modernized spraying needs to be achieved.

Fig. 11 is work plan for spraying with tractor from point A around the area of 86"116m in diameter. In order to prevent the crops from falling, it is divided to short distance nozzle range of less than 25m and long distance nozzle range of over 25m.

Fig. 12-1 is work plan. After readjustment of arable land to 100mX20m, steel pipes of 55. 7mm in inner diameter are installed in section B"C for 52m at gradient of 1/200. It is installed one per two blocks, and sprays from point B and C.

Fig. 12-2 is work plan. After readjustment of arable land to 100m X 30m, steel pipes of 55. 7mm in inner diameter are installed in section EG for 59m at gradient of 1/200. It is installed one per two blocks, and sprays from point D,

F and G.

Fig. 13-1 is work plan. After readjustment of arable land to 100m x 40m, steel pipes of 55. 7mm in inner diameter are installed in sections H~K and J~L for 52m at gradient of 1/200. It is installed in every block, and sprays from point I, K and L.

Fig. 13-2 is work plan. After readjustment of arable land to 100mX50m, steel pipes of 55. 7mm in inner diameter are installed in sections M~P and OQ for 55m at gradient of 1/200. It is installed in every block, and sprays from point N, P and Q.

Fig. 13-3 is work plan. After readjustment of arable land to 100mX60m, steel pipes of 55. 7mm in inner diameter are installed in sections R~U and T~V for 59m at gradient of 1/200. It is installed in every block, and sprays from point S, U and V. Thickness of steel pipe is 2. 1mm and is welded. For arable land larger than 100m x 60m, water distribution can be a problem, which can cause the reduced productivity and difficulty in combine to work. Therefore, steel pipe needs to be separated in the middle and installed.

5) Best mode for Carrying Out the Invention The latest technology needs to be applied to sprayer to make the sprayed particles less than 0. 3mm in diameter for the best result. In order to achieve that, most important thing is to keep water pressure over 16Kg/ci. Spraying range is 86~116 in diameter, but it is possible to increase the range by installing additional high pressure pipe. When nozzle hole gets larger, spraying distance will get longer, and spraying current quantity. upto a certain limit.

Since repulsive power is great when spraying from rice paddy, it is necessary to put 0. 6m of 1. 5m long 80mm in diameter and 4mm thick pipe into the ground, and use it with nozzle support.

If size of rice paddy is 100m and single side is 30m, safety standard of agricultural chemical in its 3000mua is 480L. Thus, from A, C, G, K, L, P, Q, U, and V of Fig. 11, 12-1, 12-2, 13-1, 13-2, and 13-3, 55L should be sprayed 37 times in 37 seconds less than 25m with short distance nozzle placed

at lower part. Then, close the nozzle and open the long distance nozzle placed at upper part to spray 181L for 37 times in 37 seconds to 25~43m area. Then close the nozzle place at upper part, and recover the rest of agricultural chemical. And, open the short distance nozzle placed at lower part from B, E, I, N, S of ridgeways. Then, 57L should be sprayed 38 times in 38 seconds less than 25m with short distance nozzle placed at lower part. Then, close the nozzle and open the long distance nozzle placed at upper part to spray 186L for 38 times in 38 seconds very thoroughly.

Inexperienced person who sprays agricultural chemical should select chemical that has no limit on spraying, so he/she can spray agricultural chemical for 2~3 times more period. It will increase the spending on agricultural chemical, but, intoxicated working hours will be decreased more than 60 times per unit area.

Thus, it is more economic way to save laboring cost. Diameters of nozzle end at the lower part are lmm, 2mm, 2mm, 3mm, and 6mm. Spraying amount is 90L/min and spraying distance is 50m in diameter.

When diameter of nozzle end at the upper part is 12. 7mm, spraying amount is 294L/min and spraying distance is 86m in diameter. When diameter of nozzle end at the upper part is 22. 9mm, spraying amount is 1008min and spraying distance is 116m in diameter.

Diameter of nozzle end can be changed variously. Power of tractor, spraying distance, spraying amount, spraying time, even distribution, etc. can be controlled, and it is made of ceramic, which is strong against abrasion.

When granule type agricultural chemical is dissolved in water and sprayed, crops can get brown and killed. It is OK to spray it before sprouting, and better to follow the warning.

For the characteristics of nozzle, higher the water pressure is, or smaller the nozzle is, diameter of particles gets smaller. And spraying distance is at its maximum when spraying angle is 24 ° 25 °.

6) Industrial Applicability It can spray agricultural chemical, fertilizer and weed killer in short amount of time. It can be used to put out the fire in the forest and the ship. It help truck replace cultivator. It can accelerate developing economic agricultural chemical. It help disposing of environmental waste. It can be used for painting. It can help provide service water, and clean and wash cars. It can help control the ground temperature. It can help improve soil condition.
