Description

Ultra low volume pesticide formulation and spray apparatus

The present invention relates to a medicament for controlling and a medicament spraying device, and more particularly, a physiological evaporative inhibitor as a medicament for spraying for controlling pests of crops grown in an enclosed place such as a greenhouse. The present invention relates to an agent for controlling drugs and an agent spraying device which is environmentally friendly and provides improved control efficiency by being sprayed by compressed carbon dioxide.

Generally, land is used as a place for growing crops or plants, but facility cultivation, such as a greenhouse, has been increasing in recent years in order to enable continuous cultivation regardless of outside temperature or season.

Facility cultivation has the advantage of shortening the crop cultivation rate and increasing the output per unit area by maintaining a stable environment suitable for crops, and is gradually increasing the growing area.

Greenhouses are characterized by constant temperatures throughout the year, resulting in stable and sustainable plant cultivation, while in the cultivation of plants, above all, they create a very suitable environment for pest infestation.

Previously, spraying was used to spray pesticides by diluting a large amount of water in chemical pesticides and spraying them with a sprayer.However, spraying of such spraying methods is toxic because it is impossible to wear protective equipment in a hot and humid greenhouse. There is a problem that the human body is exposed as it is. In addition, pests inhabit mainly on the back of the leaves of the crop, while sprayed pesticides are in contact with the front of the leaves irrelevant there is a problem that the control efficiency is low.

In particular, when spraying diluted pesticides with water, relatively large spray particles fall due to gravity, and most pesticides fall into the soil and contaminate the soil. At the same time, harmful pests and insects are also harmful to the crops inhabiting the soil. Pollution can also cause more serious diseases caused by pests.

The risk of spraying pesticides is due to the active ingredient of the pesticide, as well as the grease that the active ingredient does not dissolve well in water, and requires an emulsifier to dilute the pesticide in water, and to reduce the surface tension of water. Auxiliary agents such as a tension remover, a moisturizer to prevent evaporation, and a fixing agent and a dispersant are necessary.

Pesticides used in confined greenhouses not only cause mold development, but also cause excessive labor, risk to the human body, and overly expensive sprayers that spray pesticides.

Therefore, in order to solve the problems caused by the spray method of pesticides, fumigation control, smoke screen control or ultra-small amount spraying method has been used in various ways.

However, in the case of the fumigation method, it is only limited in its use because it is effective only in some components such as sulfur, and in the case of the smoke screen method, since the active ingredient of the pesticide is incompletely burned by high temperature heat to form smoke particles, this is also very stable against heat. In addition to some pesticides, not only can it be used, but additional diffusion agents in the granulation of active ingredients have the disadvantage of causing environmental pollution.

In recent years, the very small amount of spraying method is mainly used, but since the active ingredient of the pesticide used also has a grease, there is an uneconomic difficulty that expensive spray equipment is necessary to dilute it and atomize it into a particulate state.

In particular, the solvent used for the ultra-low-spray method is used because high boiling aromatic hydrocarbons, aliphatic hydrocarbons, and high boiling alcohols are used to cause environmental hazards, damage to plants, clogging of nozzles or deterioration of efficacy. It is diluted with water that is relatively safe for plants.

However, due to the nature of the water is easily evaporated there is a problem that the pest control effect is very low, practically impossible to use.

Accordingly, the present invention is to solve the above problems, the present invention has a main object to provide a pharmaceutical agent for the control to be environmentally friendly and harmless to the human body by using a vegetable drug extracted from a relatively safe plant to the human body.

In addition, the present invention by spraying the control agent in the form of particulates using compressed carbon dioxide gas by spraying the control agent for the control to further improve the control efficiency, such as insecticides by the control effect of the drug and the effect of increasing the effect of carbon dioxide gas Another object is to provide a device.

And another object of the present invention is to provide a chemical spraying device for controlling the cultivated crops to improve the global environment while consuming a large amount of carbon dioxide harmful to the environment.

In particular, the present invention provides a pharmaceutical spraying device for controlling the spray to stabilize the change of the spray particles due to the ambient temperature, which is a disadvantage of the conventional air atomizing nozzles, and to prevent the frequent clogging of the nozzle to achieve a stable spraying There is another purpose.

In order to achieve the above object, the control agent of the present invention is characterized in that it is made as an agent for spraying containing the active ingredient of the pesticide extracted from the plant and the pesticide active ingredient.

The pesticide active ingredient may include synthetic pesticides, microbial pesticides or sterilization, insecticides, pest pest avoidance, appetite suppression, plant essential oils having effect of growth control, plant extracts.

The vegetable evaporation inhibitors include fatty acid monoalkyl esters produced by transesterification from plant essential oils or vegetable oils and fats.

In addition, the drug spraying device for spraying the control agent of the present invention comprises a gas storage unit for storing a predetermined amount of compressed carbon dioxide gas; A supply unit for heating and supplying the compressed carbon dioxide flowing out of the gas storage unit at a constant pressure and temperature; A first pressure chamber and a second pressure chamber are formed therein, and the second pressure chamber has a nozzle tube configured to draw in and out of the first pressure chamber side nozzle to periodically clean the nozzle and the medicine supply line. A nozzle body including a nozzle unit moving member and configured to move carbon dioxide gas and a medicament through a plurality of passages connected to the first pressure chamber and the second pressure chamber; A drug receiving unit configured to store a predetermined amount of the spraying agent and to supply the compressed gas to the inside of the compressed gas through a connector coupled to the nozzle body; A gas intermittent unit for supplying the carbon dioxide gas heated through the supply unit to the first pressure chamber of the nozzle body and simultaneously supplying the carbon dioxide gas heated to the second pressure chamber of the nozzle body when the temperature of the carbon dioxide gas is equal to or higher than a predetermined temperature; And a control unit which controls the drug agitation in the medicine container and the cleaning of the nozzle and the medicine supply line by operating the gas intermittent unit according to whether carbon dioxide gas is supplied and the heating time and temperature of the carbon dioxide gas.

By using the spraying agent and the spraying device of the present invention as described above, carbon dioxide fertilization and pest control or fertilizer fertilization can be carried out at the same time, so that it is possible to efficiently consume carbon dioxide harmful to the environment in large quantities, as well as pest control efficiency. In addition, by effectively increasing the effect of carbon dioxide gas, even a small amount of synthetic or vegetable pesticides can effectively control pests, and at the same time can directly fertilize the components necessary for plant growth on the leaves of the plant It provides a very useful effect that can further promote growth.

In pesticide application, the smaller the pesticide particles, the higher the probability of reaching the pest. However, when the spray particles are small, there is a problem of easily evaporating, so in order to spray the active ingredient of the pesticide in the form of fine particles, an evaporation inhibitor for preventing evaporation is required.

Evaporation inhibitors are less volatile and can be dissolved well without reacting with the active ingredients of pesticides. They do not cause harm to plants, so they are not only safe for the environment and human body, but also require viscosity to be below a certain level.

As the medicament for spraying of the present invention as described above, the evaporation inhibitor may be provided with a natural vegetable extracted from a plant, and may be provided with a natural vegetable with an active ingredient.

Such natural vegetable evaporation inhibitors may be used plant essential oils such as castor oil, rapeseed oil, considering the weak or environmental conditions.

However, plant essential oils such as castor oil have a very high evaporation temperature and are less susceptible to weakness, while the solubility with active ingredients of pesticides is very low and the viscosity is not suitable as a spraying preparation in the form of fine particles.

Obtain the optimum spraying properties to make the solubility and viscosity suitable for the properties of the active ingredients of various pesticides, the low solubility and high viscosity characteristics, which are disadvantages of plant essential oils such as castor oil as the evaporation inhibitor in the spraying agent of the present invention In order to ensure that the vegetable fats and oils are reacted with lower alcohols such as ethyl alcohol or methyl alcohol, fatty acid monoalkyl ester from which glycerin has been removed from the product is used as an evaporative inhibitor.

The vegetable oil is preferably used at least one selected from rice bran oil, waste cooking oil, soybean oil, rapeseed oil, corn oil, castor oil, sunflower seed oil.

That is, the spraying agent to be sprayed requires an evaporation inhibitor having a viscosity suitable for taking into account the volatility and dispersion characteristics of the active ingredient of the pesticide. To this end, the present invention reacts the vegetable oil with a lower alcohol such as ethyl alcohol or methyl alcohol. While using a basic catalyst.

The basic catalyst is preferably potassium hydroxide or sodium hydroxide, and the alcohol is preferably an alcohol having 1 to 5 carbon atoms.

In addition, the vegetable oil to catalyst is preferably a weight ratio of 1: 0.001 ~ 0.02.

In the control agent of the present invention, the weight ratio of the pesticide active ingredient to the vegetable evaporation inhibitor is preferably 1: 0.1 to 150.

The control agent of the present invention is an evaporative inhibitor of the spraying formulation, in order to facilitate solubility and viscosity control, ethanol, xylene, solvent naphtha, kerosene, diesel, cyclohexanone, glycol reader, glycol, N-methylpyrrolidone (N-methyl pyrrolidone) may be used in combination of more than one.

The control agent of the present invention uses a fatty acid monoalkyl ester having an appropriate viscosity as an evaporation inhibitor in consideration of the dispersibility and volatility of the pesticide contained in the control agent.

The ratio of the evaporation inhibitor in the preparation for spraying is preferably such that the weight ratio of 1: 0.1-150 relative to the active ingredient.

Synthetic example  One From rapeseed oil  Generated Fatty acid monoalkyl ester  A

When used as a natural extract of pyrethrin as an active ingredient of pesticides, the fatty acid monoalkyl ester to be used as a suitable evaporation inhibitor is preferably an evaporation inhibitor having a relatively high viscosity in consideration of the relatively high activity and volatility of the pyrethrin.

To this end, 1000 ml of rapeseed oil in plant essential oils are heated at 120 ° C. for about 1 hour to remove water, and then 2.5 g of sodium hydroxide (caustic soda) is dissolved in 200 ml of methyl alcohol, and then mixed in rapeseed oil at 45 ° C. for 10 minutes. After about 24 hours, about 120 g of glycerin, which has settled, is removed, and fatty acid monoalkyl esters having improved viscosity and solubility can be obtained as evaporative inhibitors.

Synthetic example  2 From rapeseed oil  Generated Fatty acid monoalkyl ester  B

When using a natural plant extract nim oil as an active ingredient of a pesticide, it is preferable to use a fatty acid monoalkyl ester having a relatively low viscosity as an evaporation inhibitor in consideration of the high viscosity and relatively low activity of the nim oil.

To this end, 1000 ml of rapeseed oil is heated at 120 ° C. for about 1 hour to remove water, and 7.5 g of sodium hydroxide (caustic soda) is dissolved in 250 ml of methyl alcohol, and then put into rapeseed oil at 45 ° C. for 10 minutes. After about 24 hours, about 200 g of glycerin is removed, thereby obtaining a very low viscosity and solubility of fatty acid monoalkyl ester as an evaporative inhibitor.

The pressure regulator 11 is provided at the front end side of the supply pipe 21 as shown. It may be made, or may be provided integrally to the gas reservoir (10).

The heater 23 in the supply unit 20 may be variously formed, but it is most preferable that the heater 23 is provided as a PTC ceramic heater so that the compressed carbon dioxide gas is heated as it passes.

The nozzle body 30 is configured to allow the carbon dioxide gas and the drug to be introduced to spray the drug to the outside in the form of fine particles.

Figure 3 is an enlarged cross-sectional view showing a drug injection structure according to an embodiment of the present invention.

As shown in the drawing, the nozzle body 30 is connected to the other end of the supply pipe 21 of the supply unit 20, one end of which is connected to the gas storage unit 10, by using a heated carbon dioxide gas supplied through the supply pipe 21. Is configured to spray in the form of fine particles.

The nozzle body 30 forms a first pressure chamber 31 and a second pressure chamber 32 therein, and forms a nozzle 33 to communicate with the outside in the first pressure chamber 31. A nozzle stem moving member is provided between the pressure chamber 31 and the second pressure chamber 32.

In the nozzle body 30, a portion through which the supply pipe 21 is connected, and the first pressure chamber 31 and the second pressure chamber 32 may have passages through which a plurality of carbon dioxide gas and drugs flow.

One end of the nozzle tube 34b fixed to 34a extends to the first pressure chamber 31 so that the end of the nozzle tube 34b is formed at a position close to the nozzle 33.

Therefore, the nozzle bar movement hole 34e is formed to have a larger inner diameter than the outer diameter of the nozzle tube 34b so that the nozzle tube 34b can move forward and backward.

And the diaphragm 34c coupled to one end of the piston 34a allows the outer end to be fixed to the inner circumferential surface of the second pressure chamber 32.

The nozzle body 30 is provided with a plurality of passages. That is, the first passage 35a having a constant diameter is formed between the first pressure chamber 31 from the carbon dioxide gas inlet of the nozzle body 30 to which one end of the supply pipe 21 is connected.

The second passage 35b connected to the second pressure chamber 32 is branched from the intermediate position of the first passage 35a, and the second passage 35b is a space in which the intermediate passage forms the return spring 34d. The third passage 35c is branched so as to communicate with it.

In addition, a fourth passage 35d is formed at a lower portion corresponding to the third passage 35c in the space where the return spring 34d is formed so as to pass through the lower portion of the nozzle body 30, and the fifth passage 35e is While the lower end is formed in an adjacent position spaced apart from the end of the fourth passage (35d) of the lower end side of the nozzle body 30, the other end is connected to the drug supply tube (34f) provided in the second pressure chamber (32) do.

A chemical supply tube is provided in the nozzle tube 34b extending from the inside of the nozzle body 30 so that one end protrudes toward the second pressure chamber 32 through the center of the piston 34a provided in the second pressure chamber 32. One end of 34f is connected, and the other end is connected to an end portion of the second pressure chamber 32 side of the fifth passage 35e. At this time, it is most preferable that the drug supply tube 34f is formed to have a relatively relaxed length so as to cope with the movement of the nozzle tube 34b in the second pressure chamber 32.

The carbon dioxide gas heated through the supply unit 20 is supplied to the nozzle body 30, while the chemical liquid is supplied through the drug receiving unit 40 at the lower end thereof.

The drug receiving unit 40 is configured to simply receive a certain amount of the drug in the liquid phase as shown in Figure 2, this drug receiving unit 40 is divided again as a container 41 and the drug 42 inside do.

In this case, the container 41 has fasteners 36 and 43 formed in a shape corresponding to that of the nozzle body 30 so that the upper end thereof may be fixedly connected to the nozzle body 30. The upper end is fixed to the fasteners 36 and 43, while the lower end is provided with a pair of flow tubes 44a and 44b to be close to the bottom surface of the container 41.

In addition, the pair of flow pipes 44a and 44b have upper ends fixedly connected to lower ends of the fourth passage 35d and the fifth passage 35e of the nozzle body 30, respectively, and the fasteners 43 of the container 31. ) May be formed in a configuration in which a hole (not shown) is formed such that a pair of flow tubes 44a and 44b are inserted into the vertical tube, and the pair of flow tubes 44a and 44b has an upper end of the container 31. It may be made integrally with the fastener 43 of the ().

On the other hand, because the spraying of the drug is to spray a very small amount of liquid having different viscosity and dispersion characteristics in the space, it is almost impossible for the user to control the spraying amount during the spraying. Therefore, the drug 42 is transferred from the fastener 43 which is a lid of the container 41 which is detachably coupled with the fastener 36 formed integrally with the lower part of the nozzle body 30 as a means for controlling the spray amount. Considering the properties of the medicament 42 to be sprayed in position, the outlet 43a is formed to have an appropriate diameter thereto.

That is, the user does not adjust the spray amount, but the outlet 43a is formed in the fastener 43 to a diameter suitable for the characteristics of the chemical agent to be sprayed in the container 41, so that a separate spray amount adjusting means may be provided. There is no need, and the container 41 is coupled to the nozzle body 30 so that the spray amount is automatically adjusted.

However, the diameter of the outlet 43a is determined in consideration of the viscosity and dispersion characteristics of the chemical agent 42 filled in the container 41, and the outlet port 43a is one side of the flow pipe 44b connected to the fastener 43. To be connected to.

Accordingly, the lower end portions of the fourth passage 35d and the fifth passage 35e of the nozzle body 30 are coupled to the pair of flow tubes 44a and 44b by coupling the medicine receiver 40 to the nozzle body 30. Let each be connected.

Meanwhile, the drug filter 44c is connected to the lower end of the flow pipe 44b connected to the fifth passage 35e to filter the drug 42 having the large particles from the drug 42.

The drug 42 in the drug receiving unit 40 is composed of a mixture of the active ingredient and the evaporation inhibitor.

In addition, the gas intermittent part 50 of the present invention is provided in the first passage 35a of the nozzle body 30 and is configured to interrupt the carbon dioxide gas movement from the first passage 35a to the second passage 35b. . The gas intermittent part 50 is preferably made of an electronic valve, and before the gas intermittent part 50 is operated, the heated carbon dioxide gas introduced through the supply part 20 only through the first passage 35a is removed. 1 is supplied to the pressure chamber 31, when the gas intermittent part 50 is operated, the end part of the 2nd passage 35b side is opened, and the heated carbon dioxide gas guide | induced from the supply part 20 and the 1st pressure chamber 31 are carried out. Together, the second pressure chamber 32 is also supplied.

On the other hand, the control unit 60 of the present invention controls the operation of the gas control valve 22 and the heater 23 and the gas control unit 50 while controlling the operation of the present invention. In particular, a temperature sensing port 61 is provided at an end portion to which the supply pipe 23 of the first passage 35a is connected so that carbon dioxide heated when the carbon dioxide is heated by the driving of the heater 23 while supplying carbon dioxide gas at a constant pressure. The temperature detection port 61 senses the temperature of the gas to control the operation of the gas intermittent unit 50 according to the temperature state at this time. In addition, the control unit 60 stops the driving of the gas intermittent unit 50 for a predetermined period or time, and restarts it to perform cleaning on the nozzle 33, the nozzle tube 34b, and the medicine supply passage.

In such a chemical spraying method, it may be sprayed only by carbon dioxide gas, but it is more preferable to spray uniformly in a wider space by forced blowing.

Figure 4 is a schematic diagram of adding a forced blowing structure of the drug to an embodiment of the drug spraying apparatus according to the present invention.

In other words, the above-described drug spreading device is to enable the spraying of the drug to the fine particles by using the compressed carbon dioxide, or simply spraying with compressed carbon dioxide is not large spraying range of the drug, it is impossible to uniformly spray.

Therefore, as shown in the drawing, the drug delivery duct 70 is provided in the spraying direction of the medicine while the nozzle body 30 is accommodated, and the blower 80 is provided at the rear of the nozzle body 30 to provide the nozzle body 30. When the drug and the carbon dioxide gas is sprayed through the nozzle 33 of the), the blower 80 is operated to spray the drug and the carbon dioxide gas to a greater distance through the drug delivery duct 70.

However, although the drug is sprayed from the nozzle body 30 in the form of fine particles, at a certain distance from the nozzle 33, the chemicals are fused and collided with each other at a predetermined distance, so that the drug delivery duct of a certain distance from the nozzle body 30 is illustrated. The 70 is inclined upward at a predetermined angle so that the liquefied drug can be recovered, and the discharge port 71 is formed at each portion of the drug transfer duct 70 where spraying of the drug and the carbon dioxide is required to be uniform in a wider range. Allow the drug and carbon dioxide to be applied.

According to the above configuration, the drug is sprayed through the following process using the drug spraying device of the present invention.

The drug spreading apparatus of the present invention is controlled through the control unit 60. However, the gas storage unit 10 in which a predetermined amount of carbon dioxide gas is stored is connected to the nozzle body 30 through the supply pipe 21 of the supply unit 20, and the gas from the gas storage unit 10 to the supply pipe 21 is maintained. The movement is performed by the control unit 60 intermittently controlling the intermittent valve 22 provided in the supply pipe 21. However, the gas storage unit 10 is provided with a shielding valve 12 which can be manually operated by itself, and operates the shielding valve 12 manually while the gas storage unit 10 is connected to the supply unit 20. Compressed carbon dioxide gas is supplied from 10 to the supply part 20.

In the supply unit 20, the compressed carbon dioxide gas is interrupted by the control unit 60, and the control unit 60 is operated by an electric operation signal according to a manual operation signal or a set program command of an operator.

Before the operation signal generated by the controller 60 is generated, the gas intermittent part 50 is in a state in which the second passage 35b is blocked. When an operation signal is applied to the control unit 60 by an operator or a preset input command, the control unit 60 starts operation, and the control valve 22 of the supply unit 20 is connected to an electric signal generated by the control unit 60. The heater 23 is operated simultaneously with opening.

5 is a cross-sectional view showing the main part of the carbon dioxide gas flow structure during operation through the control unit of the drug spreading apparatus according to the present invention.

When the intermittent valve 22 is opened and the carbon dioxide gas passes through the supply pipe 21 through the supply pipe 21 at a predetermined pressure from the gas storage unit 10, the carbon dioxide gas is heated to a constant temperature and supplied to the nozzle body 30. do.

The carbon dioxide gas introduced into the nozzle body 30 checks the temperature of the carbon dioxide gas through the temperature sensor 61 in the nozzle body 30, and the temperature checked by the temperature sensor 61 is input to the controller 60. It is determined whether the stored set temperature is reached.

If the temperature of the carbon dioxide gas does not reach the set temperature, the gas intermittent part 50 continuously blocks the second passage 35b, so that the carbon dioxide gas guided through the first passage 35a is the first pressure chamber 31. Flows into.

At this time, the end of the nozzle tube 34b of the nozzle-to-moving member located in the first pressure chamber 31 is located inside the nozzle 33 by the return spring 34d, so that the heating flows into the first pressure chamber 31. The carbon dioxide gas is discharged to the outside through the nozzle 33.

Although most of the carbon dioxide gas is discharged through the nozzle 33 in the first pressure chamber 31, a part of the nozzle bar moving hole 34e which guides the nozzle tube 34b to the first pressure chamber 31 to be movable. Through the flow into the space provided with the return spring (34d) of the nozzle unit moving member, the flowing carbon dioxide is led to the drug receiving portion 40 through the flow pipe 44a on one side.

And another part of the carbon dioxide gas which flows into the 1st pressure chamber 31 flows into the nozzle tube 34b through the edge part of the nozzle tube 34b located in the 1st pressure chamber 31, and thus the nozzle tube 34b The carbon dioxide gas introduced into) flows into the container 41 of the medicine container 40 through the chemical liquid supply tube 34f, the fifth passage 35e, and the flow tube 44b.

Therefore, as the carbon dioxide gas passes through the drug supply passage, the inside of the drug supply passage is cleaned by the carbon dioxide.

The carbon dioxide gas flowing into the medicine container 40 serves to stir the medicine 42 already contained in the medicine container 40, and the stirring of the medicine 42 is more smoothly by the heated carbon dioxide gas. In this case, the viscosity is also lowered to a state suitable for spraying.

When the carbon dioxide gas is heated through the first passage 35a of the nozzle body 30 to supply an arbitrary time, the temperature of the carbon dioxide gas becomes a predetermined temperature corresponding to the characteristics of the chemical agent, and the temperature sensor 61 detects this. When delivered to the control unit 60, the control unit 60 operates the gas intermittent unit 50 to open the second passage 35b.

Figure 6 is a sectional view of the main part showing a state in which the drug is sprayed by operating the gas intermittent according to the present invention.

As illustrated, when the gas intermittent part 50 opens the second passage 35b, the second passage 35b continuously supplies carbon dioxide gas to the first pressure chamber 31 through the first passage 35a. Through the carbon dioxide gas is supplied to the space in which the return spring (34d) is built through the third passage (35c) to branch from the second passage (35b) with the second pressure chamber (32).

The carbon dioxide gas introduced into the built-in space of the return spring 34d through the third passage 35c is supplied to the medicine container 40 through the fourth passage 35d to continuously stir the medicine 42. The carbon dioxide gas supplied to the second pressure chamber 32 through the two passages 35b pushes the diaphragm 34c finely as shown in FIG. 7. At this time, the piston 34a connected to the diaphragm 34c is removed. When advancing, the nozzle tube 34b coupled to the piston 34a is interlocked so that the end portion of the first pressure chamber 31 side of the nozzle tube 34b protrudes outwardly through the nozzle 33 as shown in FIG. 8. It becomes the state to become.

When the end of the nozzle tube 34b is exposed to the outside of the nozzle 33 of the first pressure chamber 31, the nozzle tube (by the discharge pressure of carbon dioxide gas discharged through the nozzle 33 from the first pressure chamber 31) At the end of 34b), a vacuum pressure is generated.

In addition, some carbon dioxide gas still flows into the medicine container 40 through the third passage 35c, the fourth passage 35d, and the flow pipe 44a, thereby stirring the pressure inside the medicine 42. If the vacuum pressure is generated at the nozzle 33 side end of the nozzle tube 34b, the vacuum pressure is supplied to the nozzle tube 34b and the chemical supply tube 34f and the flow tube 44b connected to the nozzle tube 34b. As this occurs, the drug 42 is sucked up from the inside of the container 41.

Therefore, the drug is sprayed through one end of the nozzle tube 34b, and carbon dioxide gas is sprayed at the same time along with the sprayed drug, thereby enabling a wider range of pesticide spraying.

The spraying of such pesticides continues for a certain period of time, where they are continuously sprayed.

When spraying the drug for a long time, the carbonization of the drug is inevitably generated by the carbon dioxide gas heated at the end of the nozzle tube 34b, so that the blockage of the nozzle 33 or the end of the spray of the drug in the nozzle tube 34b is blocked. .

In order to prevent this, the controller 60 stops the operation of the gas intermittent unit 50 at a predetermined time period so that the supply of the carbon dioxide gas through the second passage 35b is stopped for a predetermined time.

When the carbon dioxide gas is no longer supplied to the second passage 35b, the pressure pushing the piston 34a is removed, and the piston 34a is returned to its original position by the return spring 34d, and the nozzle tube 34b is provided. End of the nozzle 33 moves to the inside of the first pressure chamber 31 of the nozzle 33, and heated carbon dioxide gas supplied to the first pressure chamber 31 through the first passage 35a is discharged through the nozzle 33. While removing the carbonized components adhering to the main surface of the nozzle 33 and at the same time, a part of the heating carbon gas flowed back through the nozzle tube 34b end, and the drug supply passage is reversed while the drug supply passage and the nozzle tube 34b end The cleaning is performed while removing the carbonized components formed in the.

The cleaning of the end of the nozzle 33 and the nozzle tube 34b is performed at regular intervals so that the spraying of the medicine through the nozzle tube 34b is stably performed.

In addition, where the drug spreading range is relatively large, the drug delivery duct 70 and the blower 80 may be used to uniformly spread the drug in a wide range of areas.

That is, the drug delivery duct 70 is provided at a distance from the nozzle body 30 to the position where the drug is to be sprayed, and the blower 80 is provided at one end of the drug delivery duct 70 so that the nozzle body ( 30 to spray the medicament to be sprayed from a farther, and in the drug spraying position to form a discharge port 71 in the drug delivery duct 70 to be uniform drug spraying is made.

The drug delivery duct 70 for transporting the medicine is most preferably such that the discharge port 71 is directed toward the bottom of the leaf of the crop while passing through the bottom of the crop.

Various bees and pests in crops usually inhabit the bottom of the leaves, so it is best to make contact with the bottom of the leaves.

On the other hand, the drug delivery duct 70 is provided so that a predetermined distance in the direction of the drug spraying from the nozzle body 30 is inclined upward so that the drug sprayed from the nozzle body 30 falls on the bottom of the drug delivery duct 70 by condensation They can be collected to the nozzle body 30 side and at the same time can be recovered to the container 41 of the drug receiving portion 40, thereby preventing unnecessary loss of the drug.

When spraying the drug in the form of fine particles using the drug spraying device of the present invention, a large amount of carbon dioxide, which is difficult to process, is used to promote the growth of crops, which makes it very useful to consume natural vegetable preparations. To protect the soil with the worker.

In particular, if the drug transport duct 70 to move the drug can be sprayed to the bottom surface of the crop while passing through the bottom of the crop can be more effective control.
