2. Description of the Related Art A device for simply killing insects by electric shock is disclosed in Japanese Patent Publication No. Sho 58
It has been used for a long time, such as -58055 and Japanese Utility Model No. 59-105878, but it is not a survey of specific pests that serve as a guideline for spraying pesticides. Met. However, today, the social environment has become such that the minimum amount of pesticide spraying must be taken into consideration in consideration of human safety and the environment. For that purpose, it has become necessary to grasp the occurrence of the target pest accurately and quickly and spray the pesticide efficiently. Various methods have been used as shown in FIG. 2 to know the occurrence of pests. These methods include: Attraction method, 2. 2. Capture insect killing method; Counting methods are roughly classified into three types, and methods and apparatuses of various combinations thereof have been used.

[0003] Methods of attraction include electric lamps of various wavelengths, fragrances preferred by insects, female and male sex pheromone agents, and color plates for attracting insects such as yellow. The capture and killing methods include
There are methods such as submersion with a surfactant, adhesive plates, electric shock at a high voltage, and invitation to a container for insecticides. The counting method includes a visual counting and an automatic counting, and the automatic counting includes a method of detecting an electric shock spark signal, a passing photoelectric count, and an image processing. Those which are currently in practical use are used in various combinations. Among these, the invention under the condition that the attracting method is a pheromone agent, the capturing and killing method is electric shock, and the counting method is automatic,
0-135043 and JP-A-2000-50. Further, Japanese Patent Application Laid-Open No. 2000-50 discloses an automatic counting method and an electric shock spark signal detecting method. In the invention of Japanese Patent Application Laid-Open No. 2000-50, the electric shock parts are provided in two upper and lower stages, the first stage is weakly applied, and the second stage is applied with a strong voltage to increase the insect catching rate and the counting accuracy. Has a complicated structure, and cannot remove dead insect pests attached to the electrodes.

[0004]

In conventional electric shock insects and electric shock type automatic counting traps, two
There were two issues. One is that insects attach to the electrodes. In order to respond to various kinds of insects, from large insects to small insects, over a period of several weeks and one month, the electrode part must be kept clean at all times in order to continue counting accurately. Various measures were taken to prevent adhesion.
For example, selection of AC and DC of power supply, selection of power supply voltage, selection of electrode circumference, interval, length, material and spark time, etc.The best conditions were selected from the results of various experiments. Could not be prevented. The second problem is that an open structure is desirable in order to attract and trap many insects. However, on the contrary, when the electrode gets wet due to the rainfall in rainy weather, discharge occurs, and this discharge occurs. There was a problem that it was mistakenly counted as an insect. An object of the present invention is to solve these two problems.

[0005]

The present invention employs the following means to solve the above-mentioned problems. In a pest attracting means and an electric shock type automatic counting trap that captures and counts the attracted pest by contacting the high-voltage electrode, the electrode is moved up and down to rub against a fixed partition plate to clean the electrode. The electrode is moved up and down at the time set in advance. In an electric shock type automatic counting pheromone trap that attracts and counts pests by contacting them with a high-voltage electrode, it detects rainfall, moves the electrodes up in rainy weather, goes directly under the shade, and drops To prevent discharge due to In the above or the above, the electrode is held by using an actuator, and the electrode can be moved up and down. In the above or the above, the electrodes are held by screws connected to the motor, and the electrodes can be moved up and down.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In order to remove insects adhering to an electrode portion, a means for cleaning the electrode was adopted, and the insects adhering to the electrode could be removed. If the piston moves several times regularly, it can be kept more effective and always clean. Further, by moving the electrode upward based on the signal from the rain gauge, the electrode was not wetted by water.

[0007]

An embodiment will be described with reference to FIG. 1 is a shade that prevents wind and rain. The color of the surface was yellow, which attracted insects.
Reference numeral 2 denotes an electric motor serving as a power source for vertically moving the electrodes. In this embodiment, a DC motor was used because the power source was a solar cell. Reference numeral 3 denotes a ball screw for moving the electrode unit up and down. 4 is an electrode support. The electrode support 4 is made of an insulator, and has a female thread at the center. By rotating the ball screw 3, the electrode support 4 moves up and down. Reference numeral 5 denotes a partition plate, which plays a role of scraping insects attached to the electrode part and a role of non-rotation of the electrode part, and also prevents the insects from entering the shade 1 of the driving part. Reference numeral 6 denotes an electrode portion to which a high voltage of 800 V to 3000 V is applied, and the insulator of the electrode support portion 4 has a diameter of 66 mm.
24 electrodes are buried on the circle of the above, and inserted into the apertures provided in the partition plate 5. The length of the electrode part 6 was 55 mm. Although the number, arrangement interval, and length of the electrode portions 6 are determined based on the replacement work of the pheromone agent, the size of the target pest, and the like, the electrode interval may be made variable.

Reference numeral 7 denotes a funnel where the electrocuted pests fall and are collected. Numeral 8 is a pheromone agent for pest attracting means (other attracting means may be used). Many of the effective days of pheromone 8 currently sold in the country are about one month. Therefore, the pheromone agent 8 needs to be replaced once a month, and the pheromone agent 8 can be easily removed. Reference numeral 9 denotes a control unit, which adjusts the transformation of a high voltage supplied to the electrode unit 6, sets a spark time, counts and stores the number of sparks,
It performs various controls such as time management, various settings relating to the vertical movement of the electrode support unit 4 and the electrode unit 6, signal processing from the rain gauge, and output of stored data. Numeral 10 is an example in which a flying insect touches the electrode portion and receives an electric shock. Reference numeral 11 denotes a rain gauge, and the same processing can be performed by another rain sensor.

The operating time of the electric shock type automatic counting trap of this embodiment can be arbitrarily set in accordance with the flying time of the target pest. The operating time is a time period during which the electrode unit 6 is energized and a count in that time period. Many pests mainly fly at night, and can be set arbitrarily to improve safety, power saving and accuracy. In the present invention, the electrode unit 6 inserted into the opening of the partition plate 5 is moved up and down at a predetermined time, and the dead insects attached to the electrode unit 6 are scraped off by the partition plate 5.
The timing of the vertical movement of the electrode unit 6 of the present invention may be before or after the operation time of the apparatus. However, in this embodiment, the vertical movement of the electrode unit 6 is performed once a day. Perform piston movements twice and let the insects fall down overnight. The number of pistons may be one or several. The operating time can be set arbitrarily after knowing the time zone during which the insects fly. The target pest was Chanophogosa.
This pest came in at around 17:00 in the evening, peaked at around 23:00, began to decrease at around 3 o'clock at dawn, and knew beforehand that it would not fly at around 5 o'clock at dawn. The operation time zone is set to start at 16:00 in the evening and end at 6:00 in the next morning. At 6:00, the high voltage applied to the electrode 6 is cut off, and then the operation of moving the electrode 6 up and down is started.
When the apparatus is set in the capture time period from 18:00 to 6:00 the next morning, the piston is moved several times at the end of the next morning at 6:00, and the operation is terminated.

In order to prevent a discharge between the electrode portions 6 from occurring when rain falls in rainy weather, a raindrop sensor or a rain gauge 1
In response to the signal from 1, the electrode unit 6 is moved upward and retracted. In this embodiment, when rainfall is detected by the rain gauge 11,
Evacuate to the top until the rain stops. It retracted to the upper part only at an arbitrary time zone, and then the electrode part 6 was lowered.

Next, without using a motor, the air cylinder 1
FIG. 3 shows an embodiment in which the electrode unit 6 is moved up and down by using the electrode 2. Alternatively, the electrode unit 6 may be moved up and down using a solenoid.

The measured values of the insects automatically counted are stored in the control unit 9, and the worker can go to the place as needed or transmit it to a remote place by radio (or a telephone line or the like).
investigate.

[0013]

According to the present invention, the pests adhered to the electrode portion are automatically removed, so that the cleaning work of the operator is omitted, the counting accuracy is improved, and the maintenance is simplified. Count accuracy has been improved because it is not affected by rainfall. In addition, the structure of the device is simple, easy to understand, and inexpensive.
