More specifically, the injection amount maintenance device is installed in front of the injection nozzle of the drug injection device such as a plastic house or a livestock house in which a plurality of injection nozzles are installed. , automatic drug injection configured to circulate and connect the drug to the drug container using a drug delivery tube so that individual spray nozzles constantly maintain a constant spray volume, and adjust the height of the drug suction pipe to the spray volume maintaining device to adjust the size of spray particles It's about the device.

Conventionally, in order to spray pesticides, pesticides, disinfectants, deodorants, etc., to crops, the inside of a plastic house, livestock, etc., a portable sprayer usually worn on the back is used, or a pesticide pump is installed in a tiller, etc., and then the pesticide pump is operated by power. The user directly held the sprayer connected to the long hose and sprayed the drug.

In order to solve the inconvenience of spraying chemicals by hand, an unmanned automatic sprayer including a compressor has been introduced in a plastic house or livestock house, but an error occurred somewhere in the component, such as a nozzle clogging, so that the agent could not be sprayed or the machine stopped. Since the amount of spraying cannot be controlled uniformly, there are cases where it is difficult to properly apply to the spraying situation because the nozzle installed in the latter part of the chemical supply pipe among the plurality of nozzles does not spray the chemical properly. In this case, there was a problem in that time, effort, and cost were consumed excessively to spray the drug.

As shown in FIG. 1, the automatic drug injection device of the present invention is a drug tank and a drug pump installed around the drug tank 120 and a controller 700 and a long drug supply pipe 150 from the drug pump to a plastic house or livestock. It is configured to include an injection balance maintaining device 200 installed on the upper portion and a blower 500 for injecting a drug into the injection nozzle while supplying high-pressure air to the injection nozzle 400 and the injection nozzle 400 .

The point to be improved by the present invention is to ensure that the front or rear parts of a plastic house or a barn in which a plurality of spray nozzles 400 are installed are uniformly sprayed with each other, and the spray balance maintaining device 200 performs its main role , incidentally, foreign substances mixed with the drug can be separated and removed in a simple way.

The chemical tank installed on the floor of the plastic house or livestock is usually composed of a chemical container and a lid, and a water level sensor 650 is installed inside the chemical tank. The water level sensor 650 is installed on the bottom of the medicament to detect the depletion state of the medicament, or a water level sensor that is long attached to the side of the medicament to determine the height of the medicament level may also be installed, and an automatic medicament injection device In order to be used as a drug, it is necessary at least to detect when the drug is depleted and to be configured to automatically stop the system.

A drug pump 120 operated by a power means such as a motor is installed in the vicinity of the drug tank, and the drug is sucked from the drug tank through the drug hose and the drug is delivered to the drug supply pipe 150 . The drug filter is coupled to the end of the drug hose so that it can primarily block foreign substances going toward the nozzle.

The drug transported through the drug supply pipe 150 by the drug pump 120 is branched by the three-way connector 170 having a "T"-shaped branch and is supplied to the spray balance maintenance device 200 .

The spray balance maintaining device 200 is largely composed of a funnel part 210 coupled to the lower part, a cylindrical part 240 in the middle, and a lid part 250 on the upper part, and the funnel part 210 is coupled to the lower part of the cylindrical part. It becomes narrower as it goes down, and an outlet is formed at the bottom, and it is configured so that foreign substances introduced into the spray balance maintenance device 200 settle and gather toward the outlet. , a discharge valve 230 is coupled to the lower portion of the foreign material discharge pipe 220 and is configured to empty the foreign material by opening the valve when necessary.

Cylindrical part 240 is a part forming the outer shell of the body of the spray balance maintaining device 200, and if it is made of transparent plastic if necessary, the operating state of the buoyancy body 290 inside or the degree of deposition of foreign substances can be grasped. Convenience can be increased.

The lid part 250 has a lid shape and a flange is formed on the edge of the upper plane to cover the upper part of the cylindrical part 240. protruding from the bottom More specifically, as shown in FIG. 2 , it is preferable to separately manufacture the elbow storage connecting from the three-way valve and the portion protruding under the lid to form threads inside and outside the tube so that they are screwed together.

The lower portion of the portion protruding under the lid of the inlet pipe 260 is formed in the inner conduit at the lower end of the inlet pipe as shown in FIGS. A neck portion 280 with a hole formed in the center is formed, and a screw thread is formed on the outer side of the lower end portion.

An opening and closing groove having a narrow lower portion and a wider upper portion is formed at the lower end of the inlet pipe 260 , and a coupling nut 270 having a threaded thread is coupled to the upper inner side of the opening and closing groove.

Between the neck 280 and the opening and closing groove, a spherical hole 295 is formed at the top and a connecting rod 293 extending downward is inserted to block the neck 280 when the connecting rod 293 rises upward. The inflow of the drug is restricted, and when the connecting rod 293 goes down, the neck 280 is opened so that the drug is smoothly introduced.

At the lower end of the connecting rod 293, an empty buoyant body 290 is fixed in the shape of an empty bottle, and when the drug reaches a certain level or higher in the cylindrical portion 240, it is floated by buoyancy and rises to the upper end of the connecting rod 293. The hole 295 in the ventilator presses the neck 280 to reduce the inflow of the drug, and when the drug is below a certain level in the cylindrical part 240, the hole 295 descends to allow the drug to flow smoothly into the cylindrical part. It functions to maintain the drug flowing into the 240 to be at a constant level.

A pair of suction pipes 300 connected to the injection nozzle 400 to be described later are inserted into both edges of the lid to transfer the drug to the injection nozzle 400 .

The injection nozzle 400 used in the present invention is largely composed of a nozzle inner cylinder 410 and a nozzle outer cylinder 450 as shown in FIG. 5, and the injection nozzle 400 shown on the left is a perspective view of a combined state. And, the figure shown on the right is an exploded view in which the nozzle inner cylinder 410 and the nozzle outer cylinder 450 are separated.

The nozzle inner cylinder 410 has a cylindrical shape and a tapered portion 430 having a narrow inner diameter is formed on one side, and a flange portion 420 protruding outwardly is formed in the middle portion of the cylindrical body, and is tapered from the flange portion 420 . A thread is formed on the outside of the part 430 side. The flange portion 420 is for limiting the depth at which the nozzle outer cylinder 450 is coupled, and the tapered portion 430 is for further compressing the high-pressure air sent from the blower 500 and spraying it at a faster speed, and the nozzle inner cylinder A connection hose extending from the blower 500 or a discharge pipe of the blower 500 may be directly connected to the rear of the 410 as shown in FIG. 2 .

The nozzle outer cylinder 450 has a cylindrical shape and a thread is formed inside one side to be screwed with the nozzle inner cylinder 410, and when combined with the nozzle inner cylinder, the end of the tapered portion 430 of the nozzle inner cylinder is located on the outer periphery of the point. Entrances and exits 470 of a predetermined size are formed at intervals of 90 degrees. Of the inlet and outlet 470, the two opposite inlet and outlet 470 are holes for inserting an inlet tube 480 to be described later, and the remaining two inlet and outlet 470 are outside air inhaled during spraying of the drug, and the nozzle outer cylinder 450 is It is a hole for reinforcing the spraying force by preventing unnecessary vortices from being formed inside, and the inlet and outlet 470 in the lower part of them also serves to discharge the drug that has fallen down during the spraying of the drug.

The inner end of the pair of entry tubes 480 inserted into the inlet and outlet 470 facing the nozzle outer tube 450 is located right in front of the tapered end of the nozzle inner tube 410, and the injection end 490 facing the inside is constant. It is installed to be spaced apart by a distance, and a screw thread is formed at the outer end, respectively, and is connected to the suction pipe 300 connected from the injection balance maintaining device 200 .

The drug entering the injection balance maintenance device 200 is sucked out by the negative pressure formed according to Bernoulli's principle by high-pressure air at the end of the entry pipe 480 through the suction pipe 300 and is sprayed to the outside.

Parasites and fungi that are parasitic on the leaves of plants grown in greenhouses live on the lower part of the leaves rather than the upper part where UV rays act, and the chemical sprayed by high-pressure air stays suspended in the air for a longer period of time as the particles are smaller. The probability of attaching to the upper part of the leaf as well as the lower part of the leaf increases.

As the spraying using high-pressure air, the particles of the drug become smaller and in the form of mist, so it is further compressed through the tapered part, and the injection end 490 of the entry pipe 480 is configured to have a semi-circular shape, respectively, so that it has a straight shape. The area in contact with the high-pressure air is wider than the end of the tube to increase the generation of negative pressure, which helps to refine the particles.

Even when spraying using high-pressure air, when the amount of the drug increases, the particles become thicker, and when the amount of the drug decreases, the size of the particles tends to be small. When the length of is increased, the suction amount is reduced due to the load of the drug and the particles are miniaturized, so a screw thread is formed in the lower part of the suction pipe 300 , and the height adjustment nut 350 is coupled to the upper part of the lid part 250 to adjust the height. The length of the suction pipe 300 can be adjusted by turning the nut, and the size of the particles can be adjusted using this. When the suction pipe is raised or lowered, the position movement of the nozzle coupled to the suction pipe 300 and the blower 500 must follow, so a configuration capable of adjusting the height of the nozzle and the blower 500 must be provided. For this purpose, it is preferable to fix the bracket provided with the vertical insertion groove to the wall, and to adjust the installation height of the blower and the nozzle by using a bolt.

On the other hand, since two suction pipes inserted into the injection balance maintenance device are sucking the drug from both sides, as shown in FIG. Since the introduced drug rotates while being sucked in, a cyclone effect occurs, so that the deposition of foreign substances contained in the drug can be made more effectively.

As described above, even if a plurality of the injection balance maintaining device 200 and the injection nozzle 400 are installed, if the medicine supplied from the chemical supply pipe 150 is not sufficient, the injection nozzle installed at the rear does not have the medicine, so the injection is not performed. Since this may occur, the drug circulation pipe 600 connected to the drug tank is coupled to the end of the drug supply pipe, and the drug is injected and the remaining amount of the drug is refluxed to the drug tank.

In the present invention, a program is input to the controller 700 so that the blower 500 operates for a certain period of time even after the drug pump 120 is stopped so as not to cause the nozzle clogging problem that is common in the drug injection device, and the suction pipe 300 and the injection nozzle ( 400) is stopped after the remaining chemical is exhausted, so that the remaining chemical remains in the nozzle and hardens, thereby reducing the occurrence of nozzle clogging in the subsequent chemical injection.

In order for the drug injection device to operate automatically, a controller 700 with a program function is required, and the controller is a pump, a timer to set the operating time of the blower, a blower 500 and a pump, a water level sensor 650, a drug Power management such as presence or absence sensor, the water level sensor 650, and a program for controlling the operation according to the information of the drug presence sensor is included and configured.

The present invention configured as described above effectively removes foreign substances from the drug using a simple configuration, and even if the distance from the pump is different, the drug is sprayed evenly, and the drug can be automatically sprayed by adjusting the size of the sprayed particles according to the situation. Therefore, it can be widely used in agriculture, livestock industry, industry and commercial use where control is required.

Although the present invention described above has been described with reference to an embodiment shown in the drawings, this is merely exemplary, and various modifications and equivalent other embodiments are possible by those skilled in the art. should be made clear. Accordingly, the true technical protection scope of the present invention should be construed by the appended claims, and all technical ideas within the equivalent scope should be construed as being included in the scope of the present invention.
