Description

Quantitative supplier for agricultural chemical powder}

The present invention relates to a powder pesticide quantitative injector, and in detail, proposes a new device for quantitative injection of a powder pesticide mixed with water for quantitative supply of pesticides.

When spraying pesticides on crops, it is possible to perform mechanized work in large-scale plains, but it is difficult to automatically spray pesticides in the case of mountainous or hilly terrain in Korea, especially in the case of orchards or sloping fields, water tanks It is common to spray pesticides using a type of pesticide tank.

In various types of pesticide tanks, pesticides and water are diluted in a certain ratio and contained, and pesticides passed through the suction filter inside the pesticide tank are discharged to the outside through a suction hose by external power. You will spray pesticides. However, conventional pesticide tanks are too bulky to accommodate large amounts of pesticides (e.g., at the level of 1000 or 2000 liters), require a truck when moving, and are also difficult to load into vehicles, especially for storage. Space is required, and cleaning and maintenance are also difficult.

In addition, the conventional pesticide tank requires a separate stirrer to agitate large amounts of water and pesticides, and because the concentrated liquid tank is large, there is a problem in that the efficiency is very low to stir large amounts of pesticides in a short time, and there is a lot of energy consumption. In particular, the suction-type stirrer used in the pesticide tank has a short lifespan due to chemical reactions and physical friction with pesticides, and has to be replaced periodically, increasing the maintenance cost.

On the other hand, in a large-capacity pesticide tank, it is difficult to accurately calculate pesticides to be sprayed on agricultural crops, and pesticides are often left after the pesticide spraying operation.These residual pesticides are discharged as they are, which may cause pollution of rivers or seas. In particular, as it is not possible to calculate the exact amount of use, excessive use of pesticides may be caused, causing harm to crops or raising the possibility of producing pesticide residues that exceed the standard.

The inventor of the present application has proposed an equipment capable of continuously mixing, stirring and discharging pesticides while reducing the volume while supplying pesticides in a quantitative manner (Registration Patent 10-1849854). According to this technology, as shown in FIG. 1, the pesticide quantitative feeder 10 includes an input tank 20, a stirring tank 30, and a discharge tank 40 sequentially disposed in the outer case 11. The input tank is supplied with water from the external water supply unit, and pesticides are supplied to mix water and pesticides, and the stirring tank is disposed under the input tank, and a mixed chemical solution of water and pesticides is supplied from the input tank to uniformly agitate the pesticides. The discharge tank is disposed under the stirring tank and receives and stores the stirred chemical solution from the stirring tank, while supplying pesticides with a sprayer. For the quantitative supply of pesticides, it is necessary to quantitatively input pesticides as desired and stir with water, and a quantitative feeder 50 for distributing liquid or powdered pesticides in the amount measured in the input tank is disposed in the input tank.

Existing quantitative injection devices are mainly limited to supplying liquid fluid, and various parts such as metering pumps, flow meters, control valves, and discharge devices and complex mechanical configurations are required, and it is very difficult to quantitatively supply powder raw materials (patent application 10- 2007-0138716, Utility model application 20-2005-0034666, etc.). In addition, there is a limit to the application of the above-described pesticide quantitative feeder as a powder feeder is a laboratory device that dispenses a small amount by spraying fine powder through a nozzle or a hopper that measures and supplies grains or beans.

In order to reduce the use of pesticides and increase the efficiency of the pesticide spraying operation through the supply of a small pesticide supply device that replaces the pesticide tank, a device for quantitative injection of powdered pesticides is required. In particular, there is a need for a simple device that can automatically control powdered pesticides so that farmers do not need to measure them directly and only as much powder pesticides are injected as desired. In addition, there is a need to develop a powder quantitative injector that is easy to operate and manage, is easy to separate or clean, and is durable.

The present invention was created under the above-described technical background, and an object of the present invention is to provide a quantitative feeder capable of supplying a simple and easily quantitative supply of powdered pesticides.

Another object of the present invention is to provide a quantitative injector that has a simple technical configuration, easy operation, and can be used for various powdered pesticides.

Another object of the present invention is to provide a new device capable of injecting a desired amount of powdered pesticides without including a weighing scale.

In addition, other objects and technical features of the present invention will be presented in more detail in the detailed description below.

In order to achieve the above object, the present invention is a quantitative injector for dispensing a powdered pesticide in a measured amount, the pesticide injector body having a cylindrical structure with an open top surface and an empty inside, and disposed in the center of the main body and on the inner side. A central pillar including a driving motor and a rotation shaft, a plurality of coupling bars coupled to a lower inner surface of the main body and a lower outer surface of the central pillar and spaced apart from each other and radially disposed, and disposed on the lower surface of the central pillar to provide a lower portion of the main body. It is closed and rotates in close contact with the lower part of the main body according to the operation of the driving motor, and is inserted into the open part of the upper surface of the main body, and is connected to the upper plate and the lower surface of the upper plate with the open center extending downward vertically, and the center of the upper plate is opened. A divider including a plurality of dividing bars disposed radially with respect to the unit, at least one vibrator disposed adjacent to an outer surface of the main body and applying vibration to the main body, and a control unit for controlling the operation of the driving motor and the vibrator, The rotating plate has an opening formed in a portion thereof, and provides a powder pesticide quantitative injector further comprising an opening/closing plate for opening or closing the opening.

In the present invention, the divider is inserted into the main body so that the side of the dividing bar is in contact with the inner side of the main body and the outer side of the central pillar, and the lower surface of the dividing bar is in contact with the upper surface of the rotating plate, so that the space in the main body is divided into a plurality of unit spaces. .

In addition, in the present invention, after supplying the powder pesticide to the main body, vibration is applied to the main body to uniformly distribute the powdered pesticide inside the main body, and the unit powder divided by a divider by rotating the rotating shaft of the main body Through the step of introducing through, the powdered pesticide is injected in a quantity.

In the present invention, it is preferable that the rotating plate rotates in an angular unit corresponding to a unit powder area divided by a divider.

According to the present invention, the powdered pesticide can be supplied in a minimum unit through flattening and dividing, and mixed with water in a required amount, and quantitative injection of the powdered pesticide for a continuous pesticide supplying device is possible.

The quantitative feeder according to the present invention has a simple structure and technical configuration, is easy to operate, and can be used for various powdery pesticides, so that it can be effectively utilized in field crop cultivation, fruit tree farms, and facility farms.

In addition, the quantitative feeder of the present invention does not include a weighing scale and has few parts, so it is excellent in durability, easy to clean and manage, and can be effectively used in other devices for similar purposes in addition to supplying powdered pesticides.

The present invention relates to an improved technology of a quantitative feeder used for a quantitative feeder of pesticides of Patent No. 10-1849854, and proposes a quantitative feeder capable of continuously or intermittently injecting a powdered pesticide.

The pesticide quantitative feeder is a device for supplying a fixed amount of pesticides without using a pesticide tank when spraying pesticides in various crop cultivation or fruit farming.Water is supplied from an external water supply and pesticides are supplied so that water and pesticides are mixed. An input tank, a stirring tank disposed below the input tank and receiving a mixed chemical solution of water and agrochemical from the input tank, and uniformly stirring the pesticide; a stirring tank disposed below the stirring tank and receiving and storing the stirred chemical solution from the stirring tank. It includes a discharge tank that supplies pesticides with a sprayer.

In order to mix the powdered pesticide with water and supply it to the input tank, an injector capable of measuring and supplying the powdered pesticide in a desired amount is required. The present invention provides an injector capable of quantitatively supplying powdered pesticides without including a weight scale. In particular, it is possible to control so that the powdered pesticide contained in the packaging material is not directly measured by the farmer, but only as much as desired.

To this end, the quantitative feeder of the present invention is a cylinder-shaped feeder main body, and includes an opening portion into which powdered pesticides are injected, and includes a container main body for storing the injected powdered pesticides by dividing them into unit areas while temporarily storing them. In addition, it includes a divider inserted into the main body, and the pesticide powder charged in the cylindrical main body through the divider is divided into N regions, and prepared in the minimum weight unit of the pesticide to be added to mix with water.

An opening may be provided on the lower surface of the main body as a space for inputting the divided powder downward, and the opening may be opened and closed electronically or manually. In addition, a vibrator may be disposed adjacent to the outer circumferential surface of the main body, and by the operation of the vibrator, the pesticide charged in the main body is flattened to be uniformly distributed, and the volume and weight of the powdered pesticide in the unit area may be adjusted to be constant.

Powdered pesticides injected into the main body and divided may be sequentially injected by a unit volume, and for this purpose, a driving motor may be included to rotate the main body or rotate the lower surface of the main body. As the position of the opening of the lower surface of the main body is changed (rotated) by the operation of the driving motor, the divided powder can be sequentially dropped as much as desired.

A central column can be arranged inside the cylinder for the injection of the unit divided area through the division and opening of the powder pesticide. The outer surface of the central pillar forms a part of the divided space together with the inner surface of the main body, and a rotation shaft and a driving motor may be charged inside the middle steel pillar. In addition, a rotating plate having an opening formed therein may be connected to a lower surface of the rotating shaft, and the rotating plate may be partially rotated along the outer circumferential surface of the central column inside the main body while the rotating shaft intermittently rotates only by a predetermined angle by the operation of the driving motor. As the rotating plate rotates at a predetermined angle, powdered pesticides in a unit divided area in the main body may be sequentially dropped into the feeder through the opening of the rotating plate.

Hereinafter, with reference to the drawings, the technical configuration and effects of the present invention will be described in more detail through preferred embodiments.

2A and 2B are schematic perspective views showing a main body and a central column of a quantitative injector according to the present invention. Quantitative injector body 110 for dispensing a powdered pesticide in a measured amount is a cylindrical structure with an open upper surface and an empty interior, and the lower surface is sealed by a rotating plate to be described later. Powdered pesticides are added to the main body and temporarily stored, and the injected powders are divided into N pieces by inserting a divider and prepared as a minimum input unit. In order to insert the divider, a plurality of divider guides 111 are formed on the inner surface 112 of the main body to be spaced apart.

A central pillar 120 is disposed in the center of the main body, and the outer surface 122 of the central pillar constitutes a division bar of a divider to be described later and a division space of the main body. A driving motor 124 and a rotation shaft 126 are built into the central pillar, and the driving motor rotates the rotation shaft to generate a rotational operation of the rotating plate, which will be described later. In the present embodiment, the rotation plate is rotated by arranging the drive motor in the central column, but it is also safe to rotate the main body itself by an external power means while the rotation plate is fixed in terms of the operation of the fixed-quantity feeder of the present invention.

The central pillar is structurally coupled to the upper inner surface of the main body by extending the connection part 121 on the upper surface thereof, and a wire or the like for supplying power to the driving motor may be embedded in the connection part. In addition, a plurality of coupling bars 130 are disposed radially apart from each other on the lower inner surface of the main body and the lower outer surface of the central pillar to structurally couple the main body and the central pillar. A rotating plate to be described later is disposed adjacent to the lower portion of the coupling bar to seal the lower surface of the main body, and the upper surface of the coupling bar may be in contact with the lower surface of the dividing bar of the divider to be described later. The number of bonding bars and the arrangement interval may be determined according to the degree of dividing the powdered pesticide in the body and the size of the unit division area in the present invention.

3A and 3B are a perspective view and a bottom view of a divider of the metering dispenser of the present invention. The divider 150 includes a circular upper plate 151 with an open center and a plurality of dividing bars 152 coupled to a lower surface of the upper plate and extending vertically downward and radially disposed with respect to the center opening of the upper plate. The arrangement structure and cross-sectional shape of the dividing bar may be the same as the above-described combination, and are arranged radially spaced apart from each other around the central opening 154 as a whole. The divider may be inserted or discharged into the upper surface opening of the main body using the upper plate handle 153. According to the insertion of the divider, the powdered pesticide previously charged in the main body may be divided into a plurality of areas by the dividing bar. More specifically, the divider is inserted into the main body so that both sides of the dividing bar come into contact with the inner side of the main body and the outer side of the central pillar, respectively, and the lower side of the dividing bar comes into contact with the upper surface of the coupling bar or rotating plate. The facing surface of the bar, the inner side of the main body, the outer side of the central pillar, and the lower side of the main body (or the upper surface of the rotating plate) form a divided space. As a result, the space in the main body is divided into a plurality of unit spaces by the plurality of dividing bars. The dividing bar has a thin rectangular plate structure, and as shown in Fig. 3a, the bottom surface is formed parallel to the vertical length direction, but it is divided so that the division of the powdered pesticide is easier and the injection of the divided powdered pesticide is natural. The bottom of the bar may be inclined with respect to the vertical longitudinal direction, and more particularly, may be formed in a form inclined downward from the inner side of the main body to the outer side of the central pillar.

In a preferred embodiment of the present invention, a rotating plate is provided so that the powdered pesticide divided by rotation with respect to the main body can be injected in a divided unit. 4A and 4B show a plan view and a partial enlarged view of the rotating plate 140 of the metering dispenser of the present invention. The rotating plate is disposed under the coupling bar (as shown in FIG. 2B), and is in contact with the lower surface of the central pillar (center pillar contact portion 141) and is coupled to the lower surface of the rotary shaft inside the central pillar (rotary shaft coupling portion 142). The rotating plate is disposed on the lower surface of the central pillar to close the lower part of the main body and form the lower surface of the main body on which the powdered pesticide is seated, and can rotate while being in close contact with the lower part of the main body according to the operation of the driving motor. The rotation unit of the rotating plate is preferably rotated by an angle unit corresponding to the divided unit powder area, and may be rotated by an angle unit including two or more powder areas as needed.

The rotating plate has an opening 144 corresponding to the size of an area divided by a plurality of dividing bars of the divider, and further includes an opening/closing plate 160 for opening or closing the opening. The opening functions as a passage for dropping the powdered pesticide contained in the divided area by the divider, and the closing plate serves as a means for controlling whether the powdered pesticide falls. The position of the opening may be changed by the rotation of the rotating plate. It is preferable that the shape and size of the opening are the same as the planar shape of the unit space in the main body divided by the dividing bar of the divider.

In addition, the shape of the rotating plate is in the form of a thin disk according to FIGS. 2B and 4A, but when the bottom of the dividing bar is formed in a shape inclined with respect to the vertical length direction, the rotating plate also corresponds to this, and the central rotating shaft coupling part 142 It can be formed in the shape of a bowl that is inclined upward to the outer circumferential surface of the rotating plate as a whole.

In the present invention, at least one vibrator for applying vibration to the main body may be included, and the vibrator may be disposed adjacent to, for example, an outer surface of the main body. 5 is a perspective view showing a vibrator 170 disposed adjacent to the main body.

In order to control the operation of the above-described driving motor and vibrator, the quantitative feeder of the present invention may include a control unit by itself, and the driving motor of the quantitative feeder and the vibrator may be controlled together within the integrated control unit of the pesticide quantitative feeder.

Quantitative injection of the powdered pesticide according to the present invention, after supplying the powdered pesticide to the main body, vibration is applied to the main body to evenly distribute the powdered pesticide inside the main body, divide the powder into unit areas with a divider, and then the main body central pillar By rotating the rotating shaft of the unit, the divided unit powder is supplied to the input tank sequentially or in a required amount through the opening. This operation process is sequentially illustrated in FIGS. 6A to 6C.

First, the powdered pesticide 200 is charged into the cylinder-shaped body. The amount of the powder to be charged may be, for example, the whole packaged pesticide with the weight indicated, or divided by an amount that is easy to check the weight (amount of 1/2 to 1/3, etc.). The injected powder is initially disposed in a donut-shaped flat area between the inner surface of the main body and the outer surface of the central pillar, and maintains a non-uniform state (see FIG. 6A). In this state, a vibrator adjacent to the outer surface of the main body is operated for a certain period of time to apply vibration to the main body and the powder inside is flattened (see FIG. 6B). Then, the divider 150 is inserted into the cylinder through the upper opening of the main body to divide the powder in the cylinder into areas separated by the number of dividing bars (FIG. 6C).

The powder in the divided region corresponds to the amount of the powder in the smallest unit for mixing with water, and a plurality of powder regions of the unit volume are arranged in an arc shape to form a plurality. 7A and 7B are plan views showing a unit area in which the powdered pesticide is divided, and it can be seen that the unit powder 210 divided into N pieces is disposed at 360° (in this embodiment, it is divided into a total of 16 areas).

The plurality of unit divided areas are the minimum input units and are dropped downwards (injection tanks, etc.) as the opening 144 of the rotating plate is opened, and powders in the adjacent divided areas fall in intermittent order according to the rotation of the rotating plate. Can be (fall only by 1 unit area). In addition, if necessary, a desired amount of agrochemical can be mixed with water by continuously putting the powder in the divided regions into a multi-circuit feeder (for example, dropping two or three unit regions) and mixing them with water.

FIG. 8 is a perspective view schematically showing the injection of divided powdered pesticides, and shows a state in which the divided unit powders 210 are sequentially (1 -> 2 -> 3) supplied to the input tank 20. The input amount of the unit powder may vary depending on the amount (weight) of the pesticide to be sprayed, and the amount of powder input is calculated with a mixing ratio (dilution ratio) according to the amount of water supplied. For example, after calculating the amount of pesticides for the entire area to be sprayed and the flow rate of water supplied, and calculating the powdered pesticides for this, the amount of powder to be supplied may be sequentially added. Specifically, the input amount can be determined by the following process.

First, the weight of the unit powder area of the area charged to the main body and divided into the main body relative to the total weight of the pesticide powder to be used (the total weight of the pesticide package) is calculated as follows.

* Number of divisions / Total weight of pesticide powder -> Weight of unit division area

Next, determine the amount of pesticide that must be mixed with the supplied water. The required pesticide is calculated according to the pesticide spray area or the amount of diluted pesticide sprayed, and the powder in the unit area divided in the main body of the quantitative feeder is injected into the dispenser as much as the desired amount based on the amount of pesticide required. The powder in the unit area is sequentially dropped into the opening formed in the rotating plate while rotating the divided area in the main body, and the powder in the unit area can be injected once or in multiple circuits as necessary. Table 1 shows the amount of powdered pesticide supplied according to the dilution ratio for powdered pesticides of 500g (pesticide A), 300g (pesticide B), and 1000g (pesticide C), respectively, in the case of 25 splitters and dividing bars. Is shown by way of example.

Dilution ratio Supply amount (water) Total supply (powder) Number of unit powder input
(Unit input) Pesticide A 2% 1000g 20g 1 (25g) Pesticide B 3% 2000g 60g 5 (12g) Pesticide C 5% 4000g 200g 5 (40g)

The amount of pesticide powder and the injection speed can be determined through the rotation speed of the drive motor built into the main body and the opening/closing plate on/off time control of the rotating plate, and all control operations can be automatically controlled through an electronic circuit. I can.

In the present invention, the input tank of the pesticide quantitative feeder may include one or more quantitative feeders, and when a plurality of quantitative feeders are included, it is useful to mix different pesticides at once. 9 is a perspective view showing a pesticide quantitative feeder in which a plurality of injectors 100a and 100b are disposed. Different powder pesticides can be charged and divided into each feeder, and the required amount can be added. In some cases, it is also possible to use a plurality of feeders together when a large amount of the same powdered pesticide is added.

The powder pesticide quantitative feeder according to the present invention can be manufactured by itself and combined with other devices such as an input tank, and it is easy to separate and detach, so that it is easy to clean and manage, and is effective for other devices for similar purposes in addition to the powder pesticide supply device. It will be able to be utilized.

Although the present invention has been exemplarily described above through preferred embodiments, the present invention is not limited to such specific embodiments, and the technical idea presented in the present invention, specifically, various forms within the scope described in the claims.
