 Of course, since the lower end of the stirrer (2) is installed lower than the lower limit water level sensor (1a) because the liquid level that is injected into the liquid ratio storage tank (1) a lot of conveyed to the mixing tank 10 side, the water level reached the lower limit. Even in this case, a part of the lower end of the stirrer 2 can be kept locked in the liquid ratio to prevent burnout of the stirrer 2 itself.

In addition, when the stirrer 2 is continuously operated when the liquid ratio is filled in the liquid ratio storage tank 1, unnecessary power wasted, and the life of the stirrer 2 is shortened, so that the user can set arbitrarily through the key input unit 172. When one hour elapses (for example, 5-6 hours), it can be set to be driven by a predetermined time (for example, 10-20 minutes).

Therefore, in the microcomputer 176 of the control panel 17, the predetermined time (for example, 10 to 5 hours) set by the user as long as the water level in the liquid storage tank 1 does not reach the lower limit. -20 minutes) so as to prevent the settling of various solid materials contained in the liquid ratio, so that the stirrer 2 is in operation for a predetermined time or in the lower limit level sensor 1a even during non-operation. When the water level in the liquid storage tank (1) is detected to reach the lower limit level because the drive of the stirrer (2) in the microcomputer (176) because the stirrer (2) is operated at the user's set time, even though there is no liquid ratio Unnecessary power consumption can be prevented in advance, including burnout of the stirrer itself and a decrease in life, which can occur.

In addition, in order to prevent exposure to the outer pot of the liquid fertilizer tank (1), the liquid fertilizer pump 3 is installed in the liquid fertilizer tank (1) to operate in response to the output signal of the control panel 17 and the liquid fertilizer tank (1) performs the function of pumping and conveying the high concentration liquid ratio filled in the mixing tank 10 through the liquid ratio conveying tube (5).

In addition, the first electronic valve 4 is installed on the liquid feeding tank 5 at the rear end of the liquid feeding pump 3, and in response to the opening and closing signal output from the control panel 17, the opening and closing amount is proportionally controlled and set by the user. The liquid ratio of the amount corresponding to a value is to perform the liquid ratio supply amount control function so that the water is fed into the mixing tank (10).

On the other hand, the water pump (7) is installed in the irrigated irrigation irrigated irrigation water and the like to operate in response to the output signal of the control panel 17, the irrigation water supply pipe (8) Through the water supply to the mixing tank 10 side to perform the function.

Moreover, the 1st and 2nd electromagnetic flowmeters 6 and 9 are respectively provided on the said liquid ratio conveying pipe 5 and the irrigation water supply pipe 8, and are made | formed by the liquid ratio water pump 3 and the water pump 7, respectively. It detects the amount of liquid and irrigation water supplied to the mixing tank 10 and displays them on its own, and detects the amount as an electric signal and transmits the amount to the microcomputer 176 of the control panel 17. Will be performed.

On the other hand, in the above, the free end of the liquid-liquid conveying pipe 5 or irrigation water supply pipe 8 that delivers the liquid ratio or related water to the mixing tank 10 side is located immediately above the mixing tank 10 and the liquid ratio is The liquid and irrigation water supplied to the mixing tank 10 by the water pump 3 and the water pump 7 may be introduced into the mixing tank 10 and may be diluted with each other. Complete dilution is not expected because it is introduced into the mixing tank 10 and has a diluted form.

Therefore, in the present invention, an extension pipe 8a is further installed at the free end of the irrigation water supply pipe 8 to be inserted deeply from the upper surface of the mixing tank 10 toward the bottom surface, and the liquid-liquid transfer pipe 5 is provided. The free end portion of the irrigation water supply pipe (8) is inserted through the perpendicularly extending from the upper portion of the extension pipe (8a) through the liquid ratio conveyed through the liquid feed pipe (5) is an extension pipe of the irrigation water supply pipe (8) 8a) the first dilution by different supply pressure (water pressure) difference at the moment of introduction into the mixing tank and then dilution again (i.e., the second) while causing the vortex while flowing down into the mixing tank 10 through the extension pipe 8a. Since the liquid is introduced into the mixing tank 10, the liquid ratio and irrigation water that is moved to the mixing tank 10 side pass through the extension pipe 8a of the irrigation water supply pipe 8 and naturally dilute well over a second time.

In addition, in the present invention, the inclined discharge pipe (8b) is bent to be inclined toward one side of the mixing tank 10 at the end of the extension pipe (8a) of the irrigation water supply pipe 8 as necessary, as described above. When the dilution ratio diluted in the first and second stages in the extension pipe 8a is discharged into the mixing tank 10 through the inclined discharge pipe 8b, the mixing tank 10 is in close proximity to the inclined discharge pipe 8b. Since it hits one side wall and is diluted again in the third, it is possible to accurately dilute at a desired ratio in the process of transferring the liquid ratio and irrigation water into the mixing tank 10 without installing a separate stirrer in the mixing tank.

In addition, the mixing tank 10 is formed or constructed in a rectangular parallelepiped so as to have a predetermined volume (relatively smaller than the liquid ratio storage tank 1) by using FRP or cement, similarly to the liquid ratio storage tank 1. It is installed on one side of the liquid storage tank (1) or has a configuration formed integrally with the liquid storage tank (1) with one partition therebetween, the inside of the liquid rain or irrigation water flowing into the mixing tank (10) itself Or upper and lower water level detection sensors 10a and 10b for detecting the upper and lower limit values of the dilution liquid ratios by electric signals, respectively, and the liquid ratio conveying pipe 5 and the irrigation water supply pipe 8 are provided. The dilution ratio, which is a liquid ratio or irrigation water or a mixture thereof, which is transmitted and received, is temporarily stored and then discharged to farmland through a pipe 13 or the like when the dilution ratio supply pump 11 is driven.

In addition, the dilution ratio supply pump 11 is installed on the conduit 13 installed in a form penetrating the bottom of one side of the mixing tank 10 and the liquid rain or irrigation water itself transferred to the mixing tank 10 itself. Or they are operated in response to the output signal of the control panel 17 to the dilution ratio mixed in a predetermined ratio to perform the function of sending the water at a predetermined pressure through the conduit (13).

On the other hand, the second electromagnetic valve 12 is proportionally controlled in response to the output signal of the control panel 17 in the state installed on the conduit 13 at the rear end of the dilution ratio feed pump 11 and the mixing tank 10 The dilution ratio discharged to discharge the desired amount to the corresponding farmland through the conduit 13 to the liquid ratio or the irrigation water itself or the dilution ratio having a state in which they are mixed in a predetermined ratio.

In addition, the pipeline 13 is buried between the mixing tank 10 and the farm road 20 between the farmland and the dike 21 of the farmland, the depth of the landfill is installed to a depth sufficient to prevent freezing It is desirable to.

At this time, the pipe 13 is convenient to install a pipe having the same diameter as a whole, but the water is supplied through the diluent ratio supply pump 11 and the second electromagnetic valve 12 under the control of the control panel 17 is When transporting the coming liquid ratio, irrigation water itself, or dilution ratio to the desired farmland, the farther the distance from the dilution ratio feed pump 11 may be, the smaller the water pressure may be. It can also be installed by connecting several smaller pipes in series.

In addition, it is installed to protrude toward the farmland to one side or both sides at a predetermined interval on the outer circumferential surface of the conduit 13 to evenly discharge the liquid ratio, irrigation water itself or dilution ratio transferred through the conduit 13 to the desired farmland Several branched nozzles 14 may be provided with the same pipe having a relatively smaller diameter than the diameter of the conduit 13, but in this case, since the diameters of the branched nozzles 14 are the same, the dilution ratio from the feed pump 11 The amount of liquid ratio, irrigation water itself, or diluent ratio discharged from the branched nozzle 14, which is installed at a further distance, may be small in proportion to the hydraulic pressure difference.

Therefore, in order to prevent this, the outlet diameters of the branched nozzles 14 are formed to be smaller as the distance from the dilution ratio feed pump 11 is smaller, so that the liquid ratio or irrigation water itself discharged from all the branched nozzles 14 or Although the amount of diluent ratio may be the same regardless of the hydraulic pressure difference, in this case, the cost of manufacturing the branch pipe nozzle 14 is high, and the installation work itself is very difficult to install them in the correct position.

Accordingly, in the present invention, the manual valve 15 is further provided in the branched nozzles 14 to allow the user to arbitrarily select the amount of liquid ratio, irrigation water itself, or dilution ratio discharged through the branched nozzles 14. Not only can be adjusted, but also to control itself, regardless of the pressure difference according to the position of the respective branched nozzles (14) through the opening and closing amount of the manual valve 15 through the liquid ratio or irrigation water itself or Diluent ratio can be evenly distributed to the desired farmland.

In addition, the branched nozzles 14 have a form provided to protrude toward the farmland to one side or both sides at a predetermined interval on the outer circumferential surface of the conduit 13 as described above, and is also provided with a manual valve 15 ) Also to be exposed to the outside on the farm in order to allow the user to adjust the amount of opening and closing, the actual farm is not only a lot of people come and go, but also sometimes the farm equipment such as tractors pass through the branch pipe The nozzles 14 as well as the manual valves 15 installed thereon may be damaged by farm machinery such as a person traveling on a farm, a tractor, or the like.

Therefore, in the present invention, by providing a valve protector 16 on the outer circumferential surface of each of the manual valve 15, including a part of the branched nozzles 14, respectively installed in them, a person or a tractor traveling to or from the farm road It is possible to prevent them from being damaged by farming equipment such as the like.

At this time, by using the apparatus of the present invention can be supplied to the farmland by selecting any one of the liquid ratio, irrigation water itself or dilution ratio, when you want to discharge only the liquid ratio or irrigation water to the farmland through the manual mode irrigation water to the mixing tank 10 Alternatively, the liquid supply can be cut off and only the liquid or irrigation water flows into the mixing tank 10, and then it is discharged by transporting it to farmland. After transferring to (10), transfer it to farmland, and even insects.

In the above, if only irrigation water is discharged to farmland, there is no big problem, but if you want to automatically discharge the liquid ratio itself or dilution ratio to farmland, it is better to release it to dry farmland than water is held on the farmland. If the liquid ratio itself or dilution liquid is discharged to the farmland where the water is already held at a certain level, the liquid ratio is not diluted in the correct ratio over the whole water in the farmland, so that the liquid ratio of the portion adjacent to the branched nozzle 14 is increased. This is because there is a probability that the higher and farther away, the lower the concentration will be.

In other words, if the liquid fertilizer itself or the diluent liquid ratio is dry farmland in which the water is not caught in the farmland, the desired amount of liquid fertilizer itself or the irrespective of the position of the branch tubular nozzle 14, or This is because when the dilution ratio is released so that the level of the farmland becomes the same with only the dilution ratio itself or the dilution ratio, the concentration is even throughout the farmland.

The control panel 17 includes an A / D converter 171, a key input unit 172, a ROM 173, a RAM 174, a display 175, a microcomputer 176, and first to third pump driving units ( 177)-(179), agitator driver 180, first and second electromagnetic actuators 181, 182 and the like, and receive various detection data input from various components in real time as well as input by the user. It receives various data and executes the control program stored in the microcomputer 176 and performs the overall control function of the device.

At this time, the A / D converter 171 is the lower limit water level sensor 1a installed in the liquid ratio storage tank 1, the upper and lower limit water level sensors 10a (10b), the first in the mixing tank 10, And converts the water level and the flow rate signals detected as analog signals, respectively, in real time in the second electronic flowmeters 6 and 9 into digital signals and delivers them to the microcomputer 176.

In addition, the key input unit 172 is provided with a mode selection key, an operation stop and start key, a power switch, etc., including numeric keys, and the dilution amount of the liquid ratio relative to the amount of irrigation water supplied by the user, and the intermittent operation of the stirrer 2. In addition to setting the driving time and the one-time driving time, various functions such as the operation and the stop signal of each component, including switching to the manual or automatic mode of the device, can be input.

In addition, the ROM 173 performs a function of storing various data including a program necessary for controlling the device, and the RAM 174 temporarily stores information input from each component including various data changed by a user. And when the request of the microcomputer 176 is to perform a function that outputs this.

When the user inputs various data through the key input unit 172, the display 175 displays a data, including a mode switching display, and displays various state information in a normal state. .

In addition, the microcomputer 176 receives various detection data and state information input through the A / D converter 171 in real time, receives various data input by the user, performs a control program, and controls various components. The first to the third pump driving unit 177 to 179 generates an output signal for outputting the liquid to / from the liquid feed pump 3, the water pump 7, and the diluent in response to the output signal of the microcomputer 176. A function of controlling the driving of the non-supply pump 11 is performed.

In addition, the stirrer driver 180 performs a function of controlling the driving of the stirrer 2 in the liquid rain storage tank 1 under the control of the microcomputer 176, and the first and second electromagnetic valve drivers 181 and 182. ) Controls the opening and closing amounts of the first and second electromagnetic sides 4 and 12 in response to the output signal of the microcomputer 176.

In addition, in the present invention, the alarm driver 183 is further installed at the output of the microcomputer 176 of the control panel 17 so that the user can change the state when the liquid level filled in the liquid storage tank 1 reaches a lower limit. Filling in the liquid storage tank 1 during the operation of releasing the liquid ratio itself or dilution ratio to a specific farmland by using the device of the present invention by enabling the alarm light or alarm 184 to be seen through visual or auditory Immediately recognizing the state of exhausted liquid to make up the liquid storage tank (1) can be immediately filled with a new liquid to be transferred by using a car or the like.

On the other hand, the liquid fertilizer dilution and irrigation supply method using the device of the present invention, as shown in Figures 5a and 5b, when the power to the control panel 17 is first supplied (S1), the microcomputer 176 is a key to the user Through the input unit 172 to input the dilution ratio of the liquid ratio to the irrigation water supply amount (S2).

At this time, the dilution ratio of the liquid to irrigation water may vary depending on the type of crop, the purpose of spraying (injection), or the nitrogen content included in the liquid fertilizer itself. When the nitrogen content of the liquid solution is measured and the prescription according to the type of crop, the cultivation method, or the purpose of spraying (injection) is presented, the user can set the amount of liquid fertilizer to the irrigation water supplied according to the contents of the prescription. It is usually set at a ratio of 1-2: 10.

Therefore, if the user sets the liquid dilution ratio relative to the irrigation water supply amount according to the prescription and inputs the start key, or inputs the start key installed in the key input unit 172 to operate at the preset dilution ratio (S3), the A Through the / D converter 171, the output signal of the lower limit water level sensor 1a installed in the liquid rain tank 1 is input to determine whether the water level in the liquid rain tank 1 reaches the lower limit (S4).

As a result, if the liquid level of the liquid storage tank (1) reaches the lower limit, because there is no liquid ratio itself, the driving of all the components for supplying and discharging the liquid ratio, irrigation water itself or dilution ratio to the farmland (S5).

When performing the step (S5) to stop the driving of all the components when the water level of the liquid rain tank (1) reaches the lower limit as described above, if the device to which the method of the present invention is applied, the alarm lamp or alarm 184 is provided with the microcomputer ( 176 is configured to drive the alarm lamp or alarm 184 through the alarm drive unit 183, the user immediately recognizes that the liquid is exhausted in the liquid storage tank (1) and a necessary action, that is, a new liquid in the liquid storage tank (1) The charging operation can be performed immediately.

However, as a result of the above determination, if the water level in the liquid storage tank (1) is not the lower limit, it recognizes that the liquid rain to be discharged to the farmland is ready, this time the upper limit water level sensor (10b) installed in the mixing tank (10) It is determined whether the water level in the mixing tank 10 has reached the upper limit by receiving the output signal of (S6).

As a result of the above determination, if the water level in the mixing tank 10 is the upper limit, the dilution ratio release subroutine is performed to release the liquid ratio filled in the mixing tank 10 to the desired farmland (S7).

That is, if the water level in the mixing tank 10 is the upper limit, since the desired amount of liquid ratio and irrigation water are transferred into the mixing tank 10, the microcomputer 176 may include first and second pump driving units 177 and 178. By stopping the driving of the liquid ratio feed pump 3 and the water pump (7) through the first solenoid drive unit 181 to completely close the first electronic valve 4 for the liquid ratio supply amount adjustment (S71).

Subsequently, the microcomputer 176 outputs a control signal to the second electromagnetic valve driver 182 to open the second electronic valve 12 for adjusting the dilution ratio discharge amount to a desired opening amount, and at the same time, the diluent liquid through the second pump driver 178. By driving the non-supply pump 11 (S72) to transmit the dilution ratio in the mixing tank 10 to the farmland side through the conduit 13 to be evenly discharged to the farmland through several branch pipe nozzles 14 (S73). ).

As described above, while the dilution ratio in the mixing tank 10 is discharged to farmland (S73), the microcomputer 176 continuously inputs the state signal of the lower limit water level sensor 10b installed in the mixing tank 10. Received to detect whether the water level in the mixing tank 10 reaches the lower limit (S74).

As a result, when it is detected that the water level in the mixing tank 10 reaches the lower limit, the driving of the dilution ratio supply pump 11 is interrupted through the third pump driving unit 179, and the dilution ratio discharge amount is discharged through the second solenoid driving unit 182. After closing the 2nd electronic valve 12 for adjustment completely, it returns to the initial stage S4 of judging whether the water level in the liquid fertilizer storage tank 1 reached the lower limit.

On the other hand, if it is determined that the water level in the mixing tank 10 (S6) is not the upper limit, the liquid ratio storage tank while sending irrigation water into the mixing tank 10 until the water level of the mixing tank 10 reaches the upper limit. The liquid ratio filled in 1) also performs the dilution ratio mixing and filling subroutine that is delivered to the user in the desired ratio (S8).

In other words, when the level of the mixing tank 10 does not reach the upper limit, the microcomputer 176 first supplies the liquid ratio through the first solenoid driving unit 181 to fill the dilution ratio in the mixing tank 10. The first electromagnetic valve 4 for adjustment is completely opened, and the liquid ratio pump 3 and the water pump 7 are driven 100% through the first and second pump drivers 177 and 178 (S81).

Subsequently, the microcomputer 176 uses the A / D converter 171 to operate the first and second electromagnetic flowmeters 6 and 9 respectively installed in the liquid-liquid transfer pipe 5 and the irrigation water supply pipe 8. Through the detection of the liquid and irrigation water amount sent to the mixing tank 10 through the real-time (S82), to determine whether the dilution ratio of the liquid ratio to the irrigation water to maintain the ratio desired by the user liquid to the irrigation volume currently supplied It is determined whether the supply amount is equal to the user set amount (S83).

As a result of the above determination, if the liquid supply amount compared to the current irrigation water amount is not equal to the user's set amount (that is, the dilution ratio of the liquid ratio to the irrigation water) due to the performance difference of the liquid supply pump 3 or the water pump 7, etc., the current liquid supply amount The difference between the contrast setting amounts is detected (S84).

As such, the microcomputer 176 that detects the difference because the liquid supply amount to the irrigation water that is being transferred to the mixing tank 10 is not equal to the user's set amount, may output a non-leak control signal corresponding to the difference to the first electronic valve driver ( 181), so that the opening and closing amount of the first electronic valve 4 for adjusting the liquid ratio supply amount is further locked or opened in response to the difference (S85), so that the liquid ratio supply amount compared to the current irrigation amount is equal to the user's set amount in real time. .

In this way, in addition to detecting whether the liquid supply amount compared to the current irrigation water is equal to the user's set amount in real time, the difference is detected each time there is a difference between them, and in response to the difference, the first electronic valve for adjusting the liquid supply amount According to proportional control (S85) of the opening and closing amount of (4), the dilution ratio of the liquid ratio to the irrigation water flowing into the mixing tank 10 is always the same as the set ratio of the user, and thus the opening and closing of the first electronic valve 4 After performing proportional control so that the dilution ratio of the liquid to the irrigation water through the proportional control method can be a desired amount, the step of continuously detecting the amount of liquid and irrigation water to be sent into the mixing tank in real time (S82). Repeat the process back.

Of course, as a result of the above determination, if the liquid ratio supply amount compared to the current irrigation water amount is equal to the user's set amount, it continues to detect whether the water level in the mixing tank 10 has reached the upper limit, and the liquid ratio and irrigation water being delivered to the mixing tank 10 if it is not the upper limit value. Returning to the step of detecting the amount in real time, respectively (S82), if the upper limit is returned to the dilution ratio discharge subroutine (S7) to repeat the process of releasing the dilution ratio in the full tank 10 filled to the farmland (S86).
