  When spraying pesticides on crops, mechanized work can be performed in large-scale plains, but in the case of Japan's terrain with many mountains and hills, there are situations where automatic spraying of pesticides is difficult, especially in orchards or slopes In the case of a field, it is common to spray a pesticide using a water tank-type pesticide tank.

  Pesticides and water are diluted and stored at a certain ratio in various forms of pesticide tanks, and the pesticides that have passed through the suction filter inside the pesticide tank are discharged to the outside through the suction hose by external power, and devices such as sprayers are installed. Spread on crops through. However, existing pesticide tanks are too large (for example, about 1000 L or 2000 L) to accommodate a large amount of pesticides, require trucks when moving, and require a great deal of effort when loading on vehicles. It requires a lot of space for storage and is difficult to clean and manage.

  In addition, the existing pesticide tank requires a separate stirrer to stir a large volume of water and pesticide, and because the pesticide tank is large, efficiency is low when stirring a large volume of pesticide in a short time. There is a problem that it is very low and consumes a lot of energy. In particular, the life of the inhaler-type agitator used for the pesticide tank is shortened due to chemical reaction with the pesticide and physical friction, and the necessity of regular replacement has increased the maintenance cost.

  On the other hand, a large-capacity pesticide tank makes it difficult to calculate the exact amount of pesticide to be sprayed on agricultural products, and often leaves pesticide after the pesticide spraying operation. Such pesticide residues can be discharged as they are and cause pollution of rivers or the sea. In particular, the inability to accurately calculate the amount of consumption may lead to excessive use of pesticides, which may increase the possibility of producing agricultural products with residual pesticides exceeding the reference value, such as causing harm to agricultural products. .

  Many techniques related to pesticide tanks have been proposed. For example, Patent Literatures 1 and 2 are related to large pesticide tanks and propose an improvement plan for an additional device for stirring, but the stirring efficiency is still poor due to the large capacity of the pesticide tank itself. There are existing disadvantages in terms of mobility and management. On the other hand, although many techniques have been proposed for portable sprayers (Patent Document 3 etc.), continuous mixing, stirring, and discharging of pesticides is possible, and the volume is reduced. No equipment that can be supplied has been proposed.

FIG. 1 schematically shows the entire structure of a pesticide dispenser 100 according to the pesticide dispenser of the present invention. As shown in the figure, the pesticide quantitative supply device 100 includes a charging tank 200, a stirring tank 300, and a discharging tank 400 which are sequentially arranged. The input tank 200 receives water and an agrochemical from an external water supply unit, and mixes the water and the agrochemical. The stirring tank 300 is disposed below the charging tank 200, and receives the mixed chemical liquid of water and the pesticide from the charging tank 200 and uniformly stirs the mixture. The discharge tank 400 is disposed below the stirring tank 300, receives and stores the stirred chemical solution from the stirring tank 300, and supplies the pesticide to the sprayer.

  The outlet 205 of the charging tank 200 is connected to the upper surface of the stirring tank 300, and the outlet 305 of the stirring tank 300 is connected to the upper surface of the discharging tank 400. The input tank 200, the stirring tank 300, and the discharge tank 400 are arranged perpendicular to each other, but the arrangement may be changed as long as the chemical can flow naturally downward by gravity. In addition, the charging tank 200, the stirring tank 300, and the discharging tank 400 may be stored in the single outer case 110 for mobility and convenience of management. The input tank 200 does not have to have a large capacity as long as it can receive and mix water and the pesticide at the same time, and is preferably formed smaller than the stirring tank 300 and the discharge tank 400. The stirring tank 300 can be formed larger than the charging tank 200 and smaller than the discharging tank 400. The discharge tank 400 is preferably formed to be larger than the charging tank 200 and the stirring tank 300, and is formed to have at least the same volume as or larger than the stirring tank 300.

A charging tank 200, projecting inhaler 501, 502, and 503 are disposed you partitioned metered amount of liquid or powdered pesticide to charging tank 200. When charging tank 200 includes one or more projecting inhaler, comprising a plurality of projecting inhaler, it is useful when mixing different pesticides together in a single operation. Further, the charging tank 200 includes a first valve 210 that opens and closes the flow of water flowing into the charging tank 200 from the external water supply unit. The first valve 210 turns on / off the supply of water from the outside to the charging tank 200 under the control of a control unit (not shown).

  The stirring tank 300 includes a second valve 310 for opening and closing the flow of the chemical solution flowing from the stirring tank 300 to the discharge tank 400. The second valve 310 also turns on / off the supply of the chemical from the stirring tank 300 to the discharge tank 400 under the control of the control unit. The stirring tank 300 includes a first sensor 320 for detecting the amount of the chemical in the stirring tank 300. The discharge tank 400 has a built-in second sensor 420 for detecting the amount of the chemical in the discharge tank 400, and a chemical discharge unit 410 is connected to one side of the discharge tank 400.

The control unit (not shown) includes a control circuit such as a control panel, for example, and opens and closes the first valve 210 or the second valve 310 according to the amount of the chemical sensed by the first sensor 320 and the second sensor 420. Control. If necessary, the control unit measures the pesticide distribution amount before Kito inhaler, or by calculating the dilution ratio can be as pesticides is put into the tank 200.

  The lower surfaces of the charging tank 200, the stirring tank 300, and the discharging tank 400 are inclined downward in a direction in which the chemical solution is discharged. Further, the upper surfaces of the stirring tank 300 and the discharge tank 400 are preferably inclined upward in a direction where the first sensor 320 and the second sensor 420 are located from a location where the chemical solution is supplied, which will be described later.

The operation of the charging tank 200 will be described based on FIG. Calculated dilution ratio of water and pesticides in order to prepare the desired amount of pesticide for pesticide spraying operations, set such that the pesticide is dispensed from the throw inhaler. The first valve 210 is opened to supply water to the charging tank 200 through the water supply pipe 201. The amount of water supplied at one time can be set to, for example, 20 L in consideration of the capacity of the charging tank 200 and the stirring tank 300 and the stirring efficiency. Water supplied to the charging tank 200 may be a water supply or a tube well.

To introduce one or more of the pesticide in only the required amount from the toe inhalers. For example, the water supplied is case 20L, such an amount of capacity but only projecting inhaler to diluting in water a liquid or powdered pesticide to be introduced. Throw inhaler may be disposed a plurality, in this case, it can be introduced at a desired ratio a variety of pesticide by a required amount. The principle of projection inhaler, for example the amount and the amount of water coffee similar principles introduced by measuring the amount in the vending machine, it is diluted with respect to the amount of water a liquid or powdered pesticide is turned Determined according to the proportion, the corresponding amount of pesticide is distributed to the input device. Such a projection input will be able to use only the amount of encouragement in agricultural chemicals company.

  It is preferable that the distribution of the pesticide is started immediately after the water is supplied to the input tank 200, and that all the pesticide is supplied before the supply of the water is completed. By such an operation, all the pesticides distributed in the charging tank 200 are sent to the stirring tank 300 by water. After supplying the used amount of water, the first valve 210 is closed to be in a closed state under the control of the control unit.

  The water and the pesticide supplied to the charging tank 200 are transferred to the next stirring tank 300 while being mixed together. By forming the lower surface 204 of the charging tank 200 on an inclined surface having a different inclination from the upper surface 202, the water and the pesticide flow naturally to the outlet 205 of the charging tank 200 while being naturally mixed together. Will not remain. As described above, the supply of the pesticide to the input tank 200 is performed at an early stage after the water is supplied, and the water is continuously supplied even after the supply of the pesticide is completed. Automatic cleaning without pesticide residues. In addition, if necessary, only water can be supplied without washing the pesticide for washing the stirring tank 300 or the discharge tank 400.

  FIG. 3 shows the operation of the pesticide quantitative supply device 100 in the stirring tank 300. As the water and the pesticide are mixed, the chemical solution is sent from the charging tank 200 to the stirring tank 300 to gradually fill the inside of the stirring tank 300. The stirring tank 300 is manufactured to have a volume that can sufficiently accommodate the total amount of water supplied from the charging tank 200, for example, 20 L of water.

  The water and the pesticide are uniformly stirred in the stirring tank 300 within a short time by the vortex generating means. As the vortex generating means, a screw or a stirring hose of a sprayer can be used, but in this embodiment, the vortex is generated in the stirring tank 300 by the pump 330. After the chemical solution inside the stirring tank 300 is sent to the pump, a strong flow is generated in the process of flowing into the stirring tank 300, and as a result, the water and the pesticide are uniformly stirred inside the stirring tank 300, and relatively. Since a small amount of the chemical is stirred, the stirring time is very short, and the stirring efficiency as a whole is greatly improved.

  An intake hole 306 is formed on the upper surface 302 of the stirring tank 300. The suction holes 306 serve to discharge internal air to the outside as the chemical liquid is gradually supplied into the stirring tank 300, and the inside of the stirring tank 300 is evacuated when the chemical liquid is discharged to the discharge tank 400. To prevent The first sensor 320 senses the water level wh of the chemical in the stirring tank 300 and transmits information for controlling the amounts of water and agricultural chemicals to be injected into the stirring tank 300 to the control unit. The structure of the first sensor 320 includes a rod-shaped body and a lower disk-shaped tube 322. The rod-shaped body is inserted into the intake hole 306, and the disk-shaped tube is formed of a floating material capable of floating in water. The first sensor 320 can move up and down according to the level of the chemical in the stirring tank 300.

  The suction hole 306 is formed to be larger than the diameter of the rod-shaped structure of the first sensor 320, so that the air in the stirring tank 300 is discharged even during the vertical movement of the first sensor 320, or the external air is discharged from the stirring tank 300. So that it can be inhaled. If the water level of the chemical in the stirring tank 300 rises, the disk-shaped tube 322 of the first sensor 320 closes the intake hole 306 to prevent the chemical in the stirring tank 300 from overflowing.

The amount of the chemical in the stirring tank 300 can be sensed by a change in the vertical position of the first sensor 320 according to the chemical liquid level wh, and sufficient chemical is not supplied, or the stirred chemical is supplied to the discharge tank 400 and the chemical is insufficient. by it, the first valve 210 is opened under the control of the control unit, further to satisfy the chemical liquid stirring tank 300 is supplied to the charging tank 200 of water and pesticides by projecting inhaler. The second valve 310 is turned on / off in response to reception of a signal regarding the amount of the chemical solution in the discharge tank 400 (by the second sensor 420), thereby blocking or canceling the supply of the chemical liquid to the discharge tank 400.

The lower surface 304 of the stirring tank 300 forms an inclined surface having an inclination, so that the chemical liquid can naturally flow into the discharge tank 400 through the discharge port 305. In this process, the inside of the stirring tank 300 can be washed, and the chemical liquid can be removed. It does not remain on the lower surface 304 of the stirring tank 300. The upper surface 302 of the stirring tank 300 has an inclined surface that is inclined from the outlet 205 of the charging tank 200 toward the intake hole 306 of the stirring tank 300. The upper surface 302 of the stirring tank 300 allows the bubbles generated during the stirring process to be easily removed through the suction holes 306, and the bubbles collect on the suction holes 306 instead of the discharge ports 205 of the charging tank 200, so that the charging tank 200 can be removed. by bubbles flows, it is possible to prevent the bubbles from flowing back to the throw inhaler (if such bubbles consolidate the powdered pesticide, there is a problem that quantitative turned is difficult).

  In addition, due to the inclined structure of the upper surface 302 of the stirring tank 300, the upper volume of the stirring tank 300 decreases as it goes upward, so that the chemical liquid fills the stirring tank 300 and the rising speed of the chemical liquid level along the inclined surface increases. Therefore, the vertical movement of the first sensor 320 is increased, and the accuracy of the measurement with respect to the water level change is increased. If the upper surface 302 does not have an inclined structure, the chemical liquid in the stirring tank 300 swells, or noise occurs when the stirring tank 300 is temporarily inclined, so that it is difficult to grasp the accurate water level change. There can be.

  A stirrer mounted on an existing large pesticide tank has to stir a large amount of chemical solution, and there is a problem that efficiency is greatly reduced when stirring a large amount of pesticide in a short time. On the other hand, the pesticide supply machine of the present invention is easy to perform the stirring operation, has less energy input to the stirring, and has excellent stirring efficiency. In addition, when the existing pesticide tank is used, the energy input to the agitation is 70%, and the energy consumed by the sprayer is only about 30%. Although a large-capacity engine was required, the pesticide feeder of the present invention has excellent stirring efficiency, so the engine RPM may be reduced or a small engine may be used.

In addition, the suction type agitator used for the large pesticide tank has a short life due to chemical reaction with the pesticide and physical friction, and is difficult to manage. Therefore, replacement work must be performed periodically. On the other hand, agricultural Kusurikyo supercharger of the present invention is therefore not separately require inhaler and stirrer, there is a great improvement in terms of management and maintenance costs of the pesticide reservoir.

In particular, the projecting inhaler, by performing uniform stirring to suit pesticides proportion provided by the pesticide manufacturer, to prevent locally possibility that high concentrations of pesticide are sprayed on crops safe agricultural production Can contribute to.

  FIG. 4 shows the operation of the discharge tank 400 of the pesticide quantitative supply machine. The discharge tank 400 is formed to have a maximum volume, for example, to have a volume of 30 L.

  As the chemical liquid supplied from the stirring tank 300 fills the discharge tank 400, the internal water level of the discharge tank 400 rises, and as the chemical liquid is supplied from the discharge tank 400 to the outside (to the atomizer), the chemical liquid level inside the discharge tank 400. Goes low again. An intake hole 406 is also formed in the discharge tank 400, into which the rod-shaped structure of the second sensor 420 is vertically movably inserted. Is discharged to the outside, and air flows in so that the inside of the discharge tank 400 does not become a vacuum state when the chemical is supplied from the discharge tank 400 to the outside. The disk-shaped tube 422 of the second sensor 420 is also formed of a floatable material, and moves up and down according to a change in the level of the chemical solution.

  The second sensor 420 transmits necessary information of the chemical in the discharge tank 400 to the control unit according to the change in the chemical liquid level, and according to the result, supplies the water and the pesticide to the input tank 200 and the chemical in the stirring tank 300. And the supply to the discharge tank 400 is controlled. For example, when the first liquid level wh1 of the chemical is 20 L, the chemical is continuously received from the stirring tank 300, and the second valve 310 is closed when a sufficient amount of the chemical is filled in the discharge tank 400. Further, when the second liquid level wh2 of the chemical solution is reduced to about 10 L by supplying the chemical solution to the outside from the discharge tank 400, the chemical solution is received from the stirring tank 300, and water and the pesticide are further charged into the charging tank 200. The chemical solution is continuously stirred in the stirring tank 300.

  By forming an inclined surface also on the lower surface 404 of the discharge tank 400, the chemical liquid is naturally discharged through the discharge unit 410 and does not remain on the lower surface 404 of the discharge tank 400. An inclined surface having an inclination is formed on the upper surface 402 of the discharge tank 400, similarly to the stirring tank 300. With such an inclined structure, bubbles that may be contained in the chemical solution in the discharge tank 400 can be removed through the intake hole 406, and the rising speed of the chemical solution level along the inclined surface is increased. The faster the movement, the more accurate the measurement for changes in water level. Since the overheating hole 405 is formed on the side surface of the discharge tank 400, when the spraying operation is interrupted or completed, the chemical discharged through the discharge unit 410 can flow into the discharge tank 400 again through the overheat hose 440.

  FIG. 5 is a flowchart showing a step of supplying a chemical solution using the pesticide quantitative supply device of the present invention.

Perform pesticide mixing work first to spray pesticides. By opening the first valve 210 of the charging tank 200 supplies water, subjected to feeding the pesticide in accordance with the dilution rate from projecting inhaler. When a desired amount of water and the pesticide are supplied to the stirring tank 300, the first valve 210 is closed.

  After the chemical is stirred in the stirring tank 300, the chemical is poured into the discharge tank 400. The chemical is supplied until the discharge tank 400 is filled with a sufficient amount, and the chemical in the discharge tank 400 is supplied to the sprayer or the like through the discharge unit 410 to spray the pesticide. When the spraying is temporarily stopped or the spraying operation is completed, the chemical is collected in the discharge tank 400.

  As described above, since the pesticide quantitative supply device of the present invention is small in volume, it can be easily moved by a vehicle, and can be carried by an individual if the overall size is optimized. In addition, since only the desired usage amount is used, the disposal of the pesticide remaining after the spraying of the pesticide is reduced, and as a result, the usage amount of the pesticide is reduced.

  As described above, the present invention has been exemplarily described based on the preferred embodiments. However, the present invention is not limited to such specific embodiments, and the technical concept presented by the present invention, specifically, Modifications, changes, or improvements may be made to various forms within the scope of the claims.
