Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is directed to a sprinkler for use in agriculture or horticulture, which is installed in a pressure-feeding pipe for dispersing liquid such as water, liquid fertilizer, or chemical solution. This relates to pulp that controls the entire dispersion.

[Conventional technology]

Conventionally, this type of control pulp has a structure that is opened and closed by manual control, and when performing manual control operation,
It is necessary to frequently monitor the moisture level of the plants and soil and open and close the valves to maintain the appropriate level of moisture.

Therefore, there is currently a strong demand from the agricultural and horticultural worlds for automatic control of the above-mentioned pulp in order to save labor.

[Problem that the invention seeks to solve]

As mentioned above, when trying to automatically control the pulp, it is impossible to achieve the objective by simply using a timer device to periodically apply Kn liquid, and it is difficult to achieve the goal by frequently monitoring the wetness of the plants and soil. If a device were to replace the function of opening and closing a valve to maintain an appropriate level of moisture, there was a problem in that a complicated and expensive control device would have to be used.

The present invention has been made in order to solve the above problems, and has a simple and inexpensive configuration that automatically controls the opening and closing of spraying liquid for agricultural and horticultural purposes depending on the degree of dryness of the sprayed liquid. The aim is to provide pulp.

[Means and effects for solving the problems] In order to solve the above problems, the automatic control pulp of the present invention provides a flow control system installed in pipes for spraying (including watering) for agricultural and horticultural purposes. In this on-off valve, the on-off valve is a normally closed solenoid valve that opens when energized, and includes a solar cell, a battery that stores the power generated by the solar cell, and a storage capacity of the battery that reaches a predetermined amount. When this happens, the electromagnetic valve is energized to discharge a predetermined amount within a predetermined period of time.

The principle underlying the invention is that the degree of drying of watered farmland is primarily proportional to the amount of solar radiation.

In other words, the progress of drying is determined by temperature, atmospheric humidity, and EL.
Although it is influenced by speed etc., this is the inventor's experiment.

According to research, the amount of solar radiation has the greatest influence, and even if it is considered to be proportional to the amount of solar radiation, this does not occur in practice. Therefore, when the power generated by the solar cells, which generate power in proportion to the amount of solar radiation, is integrated, it is approximately proportional to the degree of drying of the cultivated land that has been watered.

〔Example〕

Next, one embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

In FIG. 1, 1 is an agricultural water faucet, 2 is a water pipe, and 3 is a water supply hose.

A solenoid valve 4 is interposed and connected in the middle of the water supply hose 3.

This electromagnetic valve is an on-off valve that opens when energized and closes when not energized.

5 is a battery that supplies power to the electromagnetic valve 4, 6 is a control section which will be described later with reference to FIG. 2, and 7 is the battery 5.
It is a solar cell that charges the battery.

FIG. 2 is a block diagram showing details of the control section 6 described above. The charge amount integrator 6a is connected to the battery 5 by the solar cell 7.
The structure is such that the amount of charge is integrated, and when the electricity f (ampere hour) reaches a set value, the switch 6b is closed.

When the switch 6b is closed, the solenoid valve 4 is opened and water is sprayed from the sprinkler 2.

The discharge amount while the solenoid valve 4 is energized and opened is integrated by the discharge amount integrator 6c, and when the discharge amount reaches the set value, the switch 6h is opened to cut off the energization, and the solenoid valve is closed to sprinkle water. This is a configuration that stops the

A variable resistor 6b is connected in parallel with the solenoid valve 4.

If this resistance value is adjusted to a small value, the discharge current increases, the discharge amount integrator 6c quickly integrates, and watering is stopped early. Furthermore, if the resistance value of the variable resistor 6d is adjusted to a large value, the amount of discharge will gradually accumulate and the time until watering will stop will be extended.

When implementing the present invention, the variable resistor 6d may be omitted by configuring the discharge f integrator 6c so that the set value (ampere hours until the switch 6c is opened) can be adjusted.

According to the device configured as described above, when the solar cell receives sunlight for a certain period of time, the battery 5 is charged during that period,
When the amount of charge reaches the set value, the amount of charge integrator 6a is activated, the switch 6b is closed, and watering is performed.

6e is the charge f when the battery 5 is overcharged and the solar cell 7 receives sunlight and main charging does not proceed.
This is a discharge resistor provided to advance integration.

The time during which watering is performed can be adjusted arbitrarily using a variable resistor 6d.

When the amount of discharge reaches the set amount and watering is stopped, the integration of the amount of charge progresses. As mentioned above, cultivated land receiving watering8
The progress of drying is almost proportional to the amount of sunlight, so 1. The charge amount integrator 6a advances almost in proportion to the drying of the cultivated land, and restarts watering when the set value is reached.

〔Effect of the invention〕

As described in detail above, when the present invention is applied, the wetness of plants and soil can be adjusted by automatically controlling the liquid supply according to the dryness of the sprayed liquid using a valve with a simple and inexpensive configuration. It has an excellent practical effect of being able to keep the temperature at an appropriate level.

Furthermore, since the device of the present invention does not require the supply of power for driving, it is easy to install or relocate, there is no risk of troubles related to power transmission or distribution lines, and maintenance is easy and safe.
