Description

  [Technical Field] The present invention relates to a scale insect control water spray control device for controlling water spray in order to control stag beetles parasitic on tea tree branches.

When a stag beetle occurs in a tea garden, not only does the bud growth of the tea tree worsen, but also the damage that the branches and the strain die.
As a method for controlling this, a method using chemical spraying is performed. With the development of various quasi-white nozzles for spraying chemicals, it is possible to control fairly accurately. However, in order to obtain a sufficient control effect, a large amount of chemical solution is required, and about half of the sprayed chemical solution is dissipated to the ground of the tea tree.

Hatching of stag beetles is suppressed under high humidity and flooding conditions. After hatching has started, sprinklers are intermittently sprinkled so that the branches of tea trees are always wet during the day, thereby suppressing stag beetle hatching. It is known.
Three to four generations of stag beetles occur annually, with a high density in the generation with little rain during the hatching period and a low tendency in the generation with a lot of rain. For this reason, it is considered that the humidity condition has a great influence on hatching of stag beetles.

Therefore, although the screener watering is effective for the control of stag beetle, there is no control device for stag beetle by watering for that purpose.
Conventionally, as a general watering device for irrigation, there is one that can adjust watering time and stop time in units of several seconds for 1 minute to 12 hours, for example. Also, the adjustable time is the same as the watering time and the stop time. The reason for this adjustment is not to prevent specific pests but to irrigate.

Patent documents 1 and 2 etc. are proposed as a sprinkler for the purpose of the above irrigation.

As other uses, there is a watering effect that can be used for watering in the dry time such as summer. Furthermore, it can be used for holding down compost and fertilizer. Moreover, although salt damage by a typhoon is easy to generate | occur | produce, it can be used for watering in such a case and can prevent salt damage.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram for explaining an outline of a system for controlling stag beetle insects.
It is connected to the water spray control device (hereinafter referred to as “watering control device”), the valve mechanism 2 for supplying and stopping the water of the pipe by driving the electromagnetic valve 3, and the pipe of the valve mechanism 2. The sprinkler 4 is configured. When water is supplied to the sprinkler 4, water is sprinkled from the many nozzles 3 a to the tea plant 5.

The stag beetle occurs three times a year. The first generation is around May, the second generation is around July, and the third generation is around September.
Among them, the stag beetle that occurs around May can be dealt with by spraying drugs. Around July, there is relatively little outbreak of stag beetle. It is time to reap tea for the third generation stag beetle that occurs around September, so spraying chemicals should be avoided. Therefore, control by the watering control device according to the present invention is useful. Of course, the first generation and the second generation can be controlled by watering.

FIG. 2 is a view showing an example of the appearance of the watering control device according to the present invention.
The casing dimensions (vertical × horizontal × depth) of this watering control device are 200 × 223 × 101 (unit mm) and are small, and are installed on the solenoid valve mechanism as shown in FIG. The solenoid valve mechanism is one that can open and close the valve by driving the solenoid valve at a low voltage of the dry battery.
The interval selection rotary switch 11 on the left side of the front selects one of the timer times of 3 hours, 6 hours, 9 hours and 12 hours.
The water stop time selection rotary switch 10 on the right side of the interval selection rotary switch 11 is for selecting one of water stop time of 20 minutes, 30 minutes, 40 minutes, and 50 minutes for a watering time of 10 minutes. . By selecting the water stop time of the water stop time selection rotary switch 10, it is possible to repeat intermittent watering of the water stop time of 10 minutes and the selected water stop time.

On the right side of the water stop time selection rotary switch 10, a water spray display unit 16 for displaying that water is being sprayed and a water stop display unit 17 for displaying that water is being stopped are disposed. A power switch 13 is provided below the water stop display unit 17. By turning on the power switch 13, the control of the watering control device is started. Moreover, when stopping watering of the watering control apparatus in operation, by turning off the power switch 13, a water stop signal is sent to stop watering, and then the power is turned off. The power switch 13 also functions as an operation unit for stopping water during sprinkling.
Four dry batteries 14 are provided on the right side below the casing, and the power supply is 1.5v × 4 = 6v, and the water spray control device 1 is driven. When the battery becomes a predetermined voltage or lower (for example, 5.4 V or lower), the watering display unit 16 and the water stop display unit 17 are turned on at the same time to notify that the battery should be replaced.
A connection terminal base 15 is provided on the left side of the dry battery 14, and a cable drawn from each terminal of the electric circuit of the water spray control device 1 and each terminal of the battery is connected.
In addition to this, the watering control device 1 has a 24-hour clock function, and the power switch is turned on only on the first day so that it can be started at the same time from the next day.

FIG. 3 is a block diagram showing an embodiment of a circuit of a watering control device according to the present invention.
The power supply unit 23 including the power switch 27 is an output of the dry battery of FIG. 2, and supplies DC6V to the output unit 24 and DC5V to the control unit 20 and the operation unit 22. The operation unit 22 is a part of the water stop time selection rotary switch 10 and the interval selection rotary switch 11, and the operation signal is sent to the control unit 20 as a selected timer signal, for example.
The oscillation unit 21 outputs a 400 kHz signal for making time. The control unit 20 receives the timer input signal of the interval time and the water stop time selected by the operation unit 22 and counts the signal of 400 kHz to create the timer output signal of the watering time and the water stop time in the selected interval signal. . The output unit 24 receives this timer signal and outputs a watering signal of + 6V (0.5S width) when the watering time is reached. Moreover, when the water stop time comes, a water stop signal of -6V (0.5S width) is output.
The display unit (watering display unit and water stop display unit) 26 is an LED, and displays water spraying and water stopping as described above when the power switch is turned on and the timer is activated.

The electromagnetic valve 3 receives the water spray signal, opens the valve hole of the valve mechanism, and supplies water to the sprinkler. In response to the water stop signal, the valve hole is closed to stop the water supplied to the sprinkler.
For example, the mechanism shown in Japanese Patent Application No. 2001-341029 is used as the valve mechanism. Water is introduced from a pilot hole into a diagram that opens and closes a valve hole by turning on and off a solenoid valve that operates at a low voltage (battery voltage), or a diaphragm. Drain water from inside. In this way, the diaphragm is operated with the small driving force of the solenoid valve by utilizing the force of water to close the water at the branch portion of the pipe and stop the water, or to open the hole at the branch portion to supply water.

FIG. 4 is a diagram showing details of the circuit of the watering control device according to the present invention.
The control unit 20 has functions of an interval time timer circuit, a sprinkling / water stop time timer circuit, and an FF circuit that outputs a water spray pulse and a water stop pulse for operating the solenoid valve.
If the output of the interval selection rotary switch 11 input to the interval time timer circuit is selected as the interval time 6H, for example, and the output of the water stop time selection rotary switch 10 is selected as the water stop time 20M, the interval time timer circuit is turned on by turning on the power switch. Counts and divides the 400 kHz signal from the oscillator and outputs a 6H interval signal. The sprinkling / water stop time timer circuit counts and divides the 400 kHz signal, and outputs a 10-minute water spray signal and a 20-minute water stop signal repetition signal. The 6H interval signal and the repetitive signal of the watering signal and the water stop signal are input to the NAND circuit, and the NAND circuit generates the repetitive signal of the watering signal and the water stop signal within the interval time of 6H. Then, the polarity is inverted and input to the FF circuit. In the FF circuit, a watering pulse is formed at the rise of the watering signal, and a water stop pulse at the falling of the watering signal is formed.

  The output unit 24 is a relay drive circuit including a transistor, a relay circuit, and a diode, and is a circuit for driving the solenoid valve with water spray. The relay driving circuit includes a watering relay driving circuit portion that is driven by a watering pulse of the FF circuit and a water stopping relay driving circuit portion that is driven by a watering pulse of the FF circuit. When the watering pulse is input, the two contact circuits of the relay of the watering relay drive circuit are switched, and + 6V is connected to the R terminal of the solenoid valve 3, and the B terminal is grounded. A water spray pulse of + 6V, 0.5S is applied to the RB terminal of the solenoid valve, and the solenoid valve 3 opens the valve. When the water stop signal is input, the two contact circuits of the relay of the water stop relay driving circuit are switched, and the R terminal of the solenoid valve 3 is grounded and the B terminal is -6V. A -6V, 0.5S water stop pulse is applied to the RB terminal of the solenoid valve, and the solenoid valve 3 closes the valve.

FIG. 5 is a waveform diagram showing an example of control of watering time and water stopping time.
(A) shows the waveform of the interval time t _i selected and output by operating the interval selection rotary switch 11. (B) shows the waveform repeated waterproofing time t _s and the fixed time of 10 minutes watering time t _r which is selectively outputted by the operation of the water stop time selection rotary switch 10. (C) shows a solenoid valve open pulse signal output at the rising edge of the watering time t _r, the solenoid valve closing of the pulse signal output at the falling edge of the watering time t _r.
For example, interval t _i is a 6 hours, if the water stop time t _s is 20 minutes, the water spray 10 minutes during the 6-hour intervals, intermittent sprinkling water stopping 20 minutes is repeated.

  By repeatedly performing watering for 10 minutes and water stopping for the selected time within the selected interval time in this way, hatching of the stag beetle parasitic on the branch of the tea tree can be effectively killed by watering.

  This is a water spray control device for controlling stag beetle insects for controlling stag beetles that parasitize the branches of tea trees.
