That is, the portable agricultural apparatus for spraying medicine according to the present invention can easily change the connection between the hoses drawn out from the lower case 130, so that the application can be easily changed for various purposes.

4 is a conceptual diagram showing a configuration for supplying a liquid agent to the spray nozzle 910 from the reservoir 100. Referring to FIG. The spray nozzle 910 is preferably composed of a spray hose 911, a spray stage 912, and a nozzle 913. 4, when the end of the first hose 500 is connected to the end of the third hose 700 and the end of the second hose 600 is connected to the spray nozzle 910, The liquid agent in the pump 100 may be pumped by the electric pump 200 and sprayed through the spray nozzle 910. [ It is also possible to separate the sealing means 710 from the third hose 700 and the first hose 500 and then connect them using a separate connector (not shown) 4, in the case where the third hose 700 is in the form of a connector including a lock valve 711 in the middle as shown in FIG. 4, if it is necessary to seal the third hose 700, the lock valve 711 If a connection to another hose is required, the hose may be connected to the open side of the connector, and the lock valve 711 may be opened more conveniently. When the third hose 700 and the first hose 500 are connected to each other, the first hose 500 may be directly connected to the open side of the sealing means 710, One end of the connecting hose 712 is connected to the open side of the sealing means 710 and the other end of the connecting hose 712 is connected to the first hose 500, It is also preferable to use the connection connector 510 when the first hose 500 and the first hose 500 are connected. Also, when the second hose 600 is connected to the spray nozzle 910, it is preferable to connect the second hose 600 using the connection connector 610.

4, when the hose connection is made, the liquid agent in the reservoir 100 descends through the third hose 700 and the first hose 500, and by the pumping action of the electric pump 200, Is sprayed through the discharge port 220 and is supplied to the spray nozzle 910 through the second hose 600 and the liquid agent supplied to the spray nozzle 910 is sprayed through the respective nozzles 913 (See blue arrow). This example is used in the same way as a conventional portable electric atomizer. That is, if the liquid agent is contained in the reservoir 100, the portable agricultural apparatus for spraying according to the present invention can be used as a general portable atomizer.

Next, FIG. 5 is a conceptual diagram showing a connection for supplying the liquid agent from the large-capacity tank 950 at a remote place and supplying it to the spray nozzle 910. As shown in FIG. 5, in this case, there is a medicament storage tank having a large capacity at a remote place, that is, the large-capacity tank 950 far from the place where the pesticide is sprayed, 200 to the spray nozzle 910. In this case, the end of the first hose 500 is connected to the end of the extension hose 951 extending from the large-capacity tank 950, It is preferable that the spray nozzle 910 is connected to the end of the second hose 600 and the sealing means 710 is connected to the end of the third hose 700. If the sealing means 710 is of a connector type with the lock valve 711, the lock valve 711 may be simply locked. When the first hose 500 and the extension hose 951 are connected to each other and when the second hose 600 and the spray nozzle 910 are connected to each other using the connection connectors 510 and 610, .

5, the liquid agent stored in the large-capacity tank 950 at a remote location is pumped to the electric pump 200 through the extension hose 951 and the first hose 500 connected thereto The liquid agent ejected to the ejection opening 220 by the pumping of the electric pump 200 is sprayed to the respective nozzles 912 through the second hose 600 and the spray nozzle 910 connected thereto Blue arrow). However, since the third hose 700 is closed by the sealing means 710, the supply of the liquid from the reservoir 100 can not be performed. In such a case, the reservoir 100 may be empty. That is, when the liquid agent for pesticide spraying according to the present invention is used, it is unnecessary to supplement the liquid agent when the liquid agent stored in the reservoir 100 is used, and only the connection of the hose drawn out of the lower case 130 The liquid tank can be supplied with the liquid from the large-capacity tank 950 and sprayed.

6 is a conceptual diagram showing a configuration in which a liquid agent is supplied from the large-capacity tank 950 at a remote location and the reservoir 100 is charged. In this case, as in the case of FIG. 5, it is too far to supply the liquid agent from the large-capacity tank 950 at a remote place and spray it, or it is inconvenient to use the extension hose 951 by connecting the extension hose 951 4, but it is intended for the case where the liquid agent has fallen into the reservoir 100. That is, in this case, the reservoir 100 can be charged by receiving the liquid agent from the large-capacity tank 950. 6, the extension hose 951 connected to the large-capacity tank 950 is connected to an end of the first hose 500, and the end of the second hose 600 is connected to the third hose To be connected to the terminating end of the terminal 700. When the sealing means 710 is of a connector type with the lock valve 711, the end of the second hose 600 is connected to the open side of the sealing means 710, 711). When the third hose 700 and the second hose 600 are connected to each other, the second hose 600 may be directly connected to the open side of the sealing means 710 as described above. However, One end of the connecting hose 712 is connected to the open side of the sealing means 710 and the other end of the connecting hose 712 is connected to the second hose 600, 712 and the second hose 600 are connected to each other. When the first hose 500 and the extension hose 951 are connected to each other, the connection hose may be connected using the connection connector 510.

6, the liquid agent stored in the large-capacity tank 950 at a remote location is pumped to the electric pump 200 through the extension hose 951 and the first hose 500 connected thereto The liquid agent sprayed to the discharge port 220 by the pumping of the electric pump 200 passes through the second hose 600, the connection hose 712 and the third hose 700 in order, So that the reservoir 100 is filled with the liquid agent (see a blue arrow). In this case, it is further preferable that the storage container 100 further includes a water level sensor 140. In this case, when the water level sensor 100 senses a certain level, It is preferable to control the operation of the electric pump 200 to be stopped. When the liquid agent is dropped into the reservoir 100, the liquid agent is supplied from the large-capacity reservoir 950 only by changing the connection between the hoses by a simple method, (100) can be charged.

7 is a conceptual diagram showing a connection example in which the liquid agent is supplied from the large-capacity tank 950 at a remote place and the liquid agent is supplied to the third device 960 in the present invention. In this case, it is possible to supply the liquid agent to the portable agricultural chemical spraying apparatus which can not receive the liquid agent from the large-capacity tank 950, so that the storage tank can be filled. It is possible to supply a liquid agent to each portable agricultural chemical spraying apparatus even if there is only one portable chemical spraying apparatus. 7, the extension hose 951 extending from the large-capacity tank 950 is connected to the end of the first hose 500, and the end of the second hose 600 is connected to the third It is preferable to connect the hose 961 extending from the device 960 of the third hose 700 to the end of the third hose 700 by connecting the hermetically sealing means 710 to the end of the third hose 700, In the case of a connector type with a lock valve 711, it is only necessary to lock the lock valve 711. When the first hose 500 is connected to the extension hose 951 and when the second hose 600 is connected to the hose 961 extended from the third device 960, (510, 610). Here, the third device may be a conventional portable agricultural chemical spraying device, or may be a container or an apparatus requiring storage of other liquid agents or the like.

7, the liquid agent stored in the large-capacity tank 950 at a remote location is pumped to the electric pump 200 through the extension hose 951 and the first hose 500 connected thereto The liquid agent ejected to the ejection opening 220 by the pumping of the electric pump 200 sequentially passes through the hose 961 extending from the second hose 600 and the third device 960, And the third device 960 can be charged with the liquid agent (see the blue arrow). Therefore, when a plurality of people carry out the pesticide spraying operation, it is possible to conveniently supply the liquid agent to a plurality of general pesticide spraying apparatuses if there is only one pesticide spraying apparatus according to the present invention.

8 is a conceptual diagram showing a connection example in which the liquid agent in the reservoir 100 is returned to the large-capacity reservoir 950 at a remote location in the present invention. In this case, even when the pesticide spraying operation is finished or there is a need to empty the storage tank 100 for a variety of other reasons, even if the storage tank 100 does not reach the large-capacity tank 950 at a remote location, So that it can be directly returned to the large-capacity tank 950. When returning the liquid from the reservoir 100 to the large-capacity tank 950, the end of the third hose 700 is connected to the end of the first hose 500, It is preferable to connect the extension hose 951 extending from the large-capacity tank 950 to the terminating end of the expansion tank 950. The end-to-end connection method of the hose is the same as that described above with reference to Figs. 4 to 7, and therefore will not be described.

9 and 10 show a detailed structure of the overflow prevention intake and exhaust device tap 800 included in the present invention, and FIGS. 11 and 12 show cross-sectional views showing the operation principle of the overflow prevention type intake and exhaust device 800 Are shown. Hereinafter, the detailed structure and operation principle of the overflow prevention intake and exhaust tap 800 will be described with reference to FIGS. 9 to 12. FIG.

9 is an exploded perspective view showing a state in which the overflow prevention absorbing / discharging device tap 800 is divided into a lower tab 810 and an upper tab 820. FIG. 10 is an exploded perspective view of the overflow preventing / Sectional view showing a side cross section in which the upper tab 820 and the upper tab 820 are coupled to the lid 110. FIG. 9 and 10, the overflow prevention intake / exhaust device tap 800 includes a lower tab 810 inserted from the inside of the lid 110 through a hole formed in the center of the lid 110, And an upper tab 820 screwed to the lower tab 810 at an outer side of the lower tab 810. The lower tab 810 includes a support portion 813 located inside the lid 110, a male thread portion 812 connected to the support portion 813 and threaded through the hole, And a cylindrical nozzle-type intake and exhaust tube 811 connected to the male screw portion 812 and formed up to a predetermined height. The upper tab 820 further includes a female screw portion 822 having an inner circumferential surface threaded to be screwed with the male screw portion 812 and a female screw portion 822 connected to the female screw portion 822, It is preferable to include the tube protecting portion 821. It is preferable that the height of the tube protecting portion 821 is higher than the height of the intake and exhaust tube 821 and a certain space is formed between the inner circumferential surface of the tube protecting portion 821 and the outer peripheral surface of the intake and exhaust tube 811 Do.

It is preferable that the intake and exhaust tube 811 has a cylindrical nozzle shape, that is, a tubular shape having a small diameter d. If the tubular shape is a small diameter d, the intake and exhaust device suffices for supplying and filling the liquid, Even if the liquid agent enters the inside of the intake and exhaust tube 811, the liquid does not overflow to the upper end of the intake and exhaust tube 811. For this, the diameter d of the intake and exhaust tube 811 is preferably 1 to 3 mm, more preferably about 2 mm. This is because when the diameter d of the inlet / outlet tube 811 is greater than 3 mm, the possibility of overflowing the internal liquid increases. When the diameter d is less than 1 mm, the inlet / outlet efficiency of the inlet / In order to form a certain space between the inner circumferential surface of the tube protecting portion 821 and the outer circumferential surface of the inlet / outlet tube 811, the inner diameter D of the tube protecting portion 821 is set to be larger than the outer diameter of the inlet / outlet tube 811 It is preferable to make it twice as large as that of the first embodiment.

Hereinafter, the operation principle of the overflow prevention intake / exhaust device tap 800 will be described with reference to FIGS. 11 and 12. FIG. FIG. 11 shows the principle that the overflow prevention absorption and exhaustor tap 800 is not overflowed beyond a certain angle, and FIG. 12 shows the principle that overflow prevention is prevented by surface tension below a certain angle. 11 (a) shows a case in which the intake and exhaust tube 811 has a large diameter d ', for example, 1 cm or more. In this case, the liquid agent in the reservoir 100 has a constant angle? The angle of the water surface of the liquid agent with respect to the tube), the water surface WL becomes higher than the lower end o of the outlet side of the inlet / outlet tube 811, so that the liquid agent has to flow out. 11 (b) shows a case in which the intake and exhaust tube 811 has a narrow diameter d, for example, 2 mm under the same conditions. In this case, the lower end o of the intake and exhaust tube 811, It becomes higher than the water surface (WL), so that the liquid agent does not flow out. That is, as shown in FIG. 11, it is advantageous to prevent the overflow of the liquid agent as the diameter of the inlet / outlet tube 811 becomes narrower when tilted at the predetermined angle? With respect to the water surface WL under the same condition. That is, as the diameter of the inlet / outlet tube 811 is narrower, the reservoir tilts more to cause the liquid agent to flow out.

In addition, when the storage container 100 is tilted more and more and the predetermined angle? Becomes smaller (? ->? '), As shown in FIG. 12 (a) 811 may have a higher height difference between the water surface WL and the lower end o of the outlet side of the intake and exhaust tube 811 while allowing air to be sucked into the reservoir 100 through the intake and exhaust tube 811 The liquid agent easily overflows. However, as shown in FIG. 12 (b), in the intake and exhaust tube 811 having the narrow diameter d, the surface tension σ is generated inside due to the narrow diameter d , The lower end of the boundary line of the liquid agent in the interior of the intake and exhaust tube 811 is formed on the lower side of the water surface WL due to the surface tension?. In addition, since the liquid agent blocks the entire intake and exhaust tube 811 and the surface tension? Is formed, air can be prevented from being sucked into the inside. Therefore, even if the reservoir 100 is further inclined, the outside air can not be sucked in, so that the pressure difference between the inside and outside of the reservoir 100 can be prevented, thereby preventing the liquid in the inside from overflowing. As described above, since the portable medicine spraying apparatus according to the present invention includes the overflow prevention intake and exhaust device tap 800 having the above-described characteristics, even if the reservoir 100 is inclined, the liquid agent in the reservoir 100 can be sucked So that it is not overflowed.
