Description of the Related Art Conventionally, a power source such as a motor is used to change a rotary motion into a reciprocating motion to move a diaphragm to inhale and discharge a chemical liquid to inject the chemical liquid. In recent years, electromagnetic linear type chemical liquid injection pumps that use electromagnets instead of this motor have been marketed, but they all require a commercial power source of 100 or 200 volts,
I couldn't use it without a power supply. Also,
Since suction and discharge of the chemical solution are repeated by moving the diaphragm back and forth, considering the fatigue of the diaphragm, there is a drawback that the stroke cannot be made large and the discharge amount for one time becomes small. There was a suction-type diluter that injects without using electricity, but the injection amount could not be controlled and the dilution ratio became unstable, so it has not been put to practical use.

である。The prior art required a strong commercial power source because it used a motor and an electromagnet, but in the agricultural field where the inventor is engaged, most fields do not have power sources, such as sprinklers. Even if you want to spray pesticides and liquid fertilizers automatically with, you have to load a yellow chemical solution tank on the truck and handle the pesticide with a power sprayer, and you are at risk of inhaling the pesticide during spraying. I had a problem. Also, as mentioned above, the stroke is shortened to reduce the fatigue of the diaphragm and the discharge amount per stroke is limited. Therefore, especially when a large amount of dilution water must be sprinkled with a sprinkler, etc. Since the infusion pump also needed a large-sized one, the necessity of the commercial power source was increasing more and more. The product of the present invention does not require a commercial power source, does not use a motor drive or an electromagnet, and moves a piston by utilizing the pressure of the water supply main, and easily develops a pump that can discharge a large amount of liquid and can inject a chemical liquid with a small electric power. The purpose is.

That is, the pressure water of the water supply main is switched, and the chemical liquid is injected by moving the piston 3 by utilizing the difference in water pressure applied to the piston 3 in each liquid chamber, so that the injection can be easily performed even by a manual operation. In addition, it can be automated with a small power source such as a solar power source because it only switches the three-way valve.
Since a diaphragm is not used, it is possible to secure a sufficient stroke and discharge amount.

The piston 3 moves to the left in the figure because it is released at this time. At this time, the liquid chamber 7
The chemical solution in the chemical solution tank is sucked into the tank via the check valve 5.

Moves to the right in the figure. At this time, the chemical liquid in the liquid chamber 7 and the liquid chamber 7 of the piston 3 and the liquid chamber 7 receive the water pressure.
Due to the difference in pressure caused by the size of the area receiving the water pressure, the water is compressed and injected into the water main via the check valve 6. The above process is repeated continuously.

It is released and moves to the left in the figure by the pressure of the built-in spring 14 to suck the chemical liquid as described above. At this time, the pushing pressure of the spring is as shown in FIG.
Has a force to be pressed against the liquid chamber 9, and is set to be weaker than the total pressure when the pressure of the main water supply pipe is applied to the cross-sectional area of the piston 3 on the liquid chamber 9 side.

Since the total pressure applied to the cross-sectional area of the piston 3 prevails, the piston 3 moves to the right side in the drawing, and the chemical liquid is injected into the water supply main. Continuous injection is performed by repeating the above process.

Next, the chemical liquid in the chemical liquid tank is sucked in via the check valve 5. Next, when the three-way valves A and B are switched as shown in FIG. 3, the pressure of the main water supply pipe is applied to the liquid chamber 9 this time, and the liquid chamber 8
The internal pressure of is released to the atmospheric pressure. At this time, since the cross-sectional area of the piston 3 on the liquid chamber 7 side is smaller than the cross-sectional area on the liquid chamber 9 side, the piston 3 moves to the right in the drawing and the chemical liquid in the liquid chamber 7 is moved.

The basic connection method does not change, but the three-way valve A is removed,
A spring 14 is provided in the liquid chamber 8 so that the piston 3 is pressed against the liquid chamber 9 side when there is no load. The operation is almost the same as in the first embodiment, but when the three-way valve B is switched as shown in FIG. 4, the liquid chamber 9 becomes unloaded, so the liquid chamber 9 is compressed by the force of the spring 14. At this time, the liquid chamber 7 is compressed. A chemical liquid is injected into the liquid chamber from the check valve 5. Next, as shown in FIG. 5, when the three-way valve B is switched to apply water pressure to the liquid chamber 9, the pressure applied to the piston causes the spring 14 to contract, and at the same time, the liquid chamber 7 The medicinal solution is compressed and is injected into the water main via the water main connection port 2.

As shown in FIG. 6, a freely rotating pinion gear 17 is provided near the center of the inside of the cylindrical main body C, and two sets of pistons 15 and 16 provided with a rack gear that is connected to engage with the pinion gear 17 are provided. When the three-way valves A and B are switched as shown in FIG. 7, the water pressure of the main water supply pipe is applied to the liquid chamber 9, and the piston 15 is pressed rightward in the drawing. At this time, the piston 16 connected by a gear changes the pressure applied to the liquid chamber 9 by a rack and pinion gear, and starts to move to the left in the figure at the same time as the piston 15, contrary to the piston 15.
At this time, the liquid chamber 7 has a negative pressure and sucks the chemical liquid from the check valve 5.

, The water pressure applied to the liquid chamber 8 from the three-way valve A pushes the pistons 15 and 16 to the left and right in the figure for the reason described above. The chemical liquid in the liquid chamber 7 is not only the pressure to be pushed to the piston 16 but also the rack. As a result, even the pressure of the piston 15 which is turned by the pinion gear is received, and it is possible to inject the water into the high-pressure water main pipe without difficulty.

くすることができる。The above process is continuously repeated to inject the liquid medicine, but if the diameters of the connection ports A2 and B1 of the three-way valves A and B are made smaller than A1 and B2, the liquid medicine is sucked in rapidly and discharged. Since the liquid can be discharged slowly, the mixing efficiency of the liquid medicine can be improved without causing pulsation.

The three-way valves A and B are three-way automatic valves that operate with a small amount of electric power such as solar power, and by switching the three-way automatic valves at regular time intervals, it is possible to easily and automatically inject a chemical solution even without a commercial power source.
