Detailed ways

The present application will be further described in detail below in conjunction with accompanying drawings 1-8.

The embodiment of the present application discloses an electronic mites remover for bees, which realizes the removal of bee mites by using negative ions. Referring to FIGS. 1 and 2 , the mite removal instrument includes a housing 1 , at least one mite removal unit 2 , a circuit control board 3 and a power supply unit 4 .

The casing 1 is formed by butting the bottom casing 12 and the top casing 11 , and the bottom casing 12 is provided with a through hole 121 .

2 and 3 , the mite removal unit 2 is disposed in the housing 1, and specifically includes an anion emitting head 211 for generating negative ions, an ultrasonic generator 22 for generating ultrasonic waves, and a coil 23 for generating a magnetic field.

3 and 4, both ultrasonic waves and negative ions are emitted outward through the through holes 121, wherein the ultrasonic waves can be reflected back and forth inside the beehive and then transmitted to the depths of the honeycomb, and the bee mites will generate a phenomenon of avoidance when they hear the ultrasonic waves and climb out to the bee road. , The magnetic field sends negative ions to the bee road to shock the bee mites to shoot down the bee mites.

Specifically, there are a plurality of negative ion emitting heads 211, each negative ion emitting head 211 has a brush head 212 for releasing negative ions, and the brush heads 212 of all the negative ion emitting heads 211 are circumferentially arranged with a center point And emit negative ions to the center.

The ultrasonic generator 22 is an ultrasonic horn disposed toward the through hole 121 , and the ultrasonic horn is located on the side of the negative ion emitting head 211 away from the through hole 121 , so as not to prevent negative ions from being emitted from the through hole 121 .

The coil 23 is arranged on the back of the ultrasonic generator 22. After the coil 23 is energized to generate a magnetic field, the negative ions are accelerated and ejected from the through hole 121 in the form of parabolic scattering under the action of the magnetic field force, which can be better transported to various positions of the beehive.

The circuit control board 3 is also placed inside the housing 1 and is electrically connected with the negative ion emitting head 211, the ultrasonic generator 22 and the coil 23, and the circuit control board 3 controls the negative ion emitting head 211, the ultrasonic generator 22 and the coil 23 to open and close at the same time, Meanwhile, the circuit control board 3 has a mounting hole 31 for circumferentially mounting the negative ion emitting head 211 .

The circuit control board 3 is electrically connected with the power supply unit 4 to realize the power supply of the mite removal instrument. In this embodiment, the power supply unit 4 is set as an external power supply. In other embodiments, the power supply unit 4 can also be a continuous battery such as a battery or a solar panel. power supply.

In order to verify the mite removal effect of the electronic mite removal instrument of the present application, the applicant conducted the following experiments:

Select ten beehives with similar beehive colony potential in a beehive, denoted as hive 1, hive 2... hive 9, hive 10. At the same time, the applicant selected and observed that the parasitic rate of bee mites in each hive was about 30% before the experiment. , the parasitic rate of bee mites = the number of bees with mites / the total number of bees examined.

in:

Two above-mentioned electronic mites removers are arranged in the first and second beehives, and the negative ions of the mites removal unit 2 of the electronic mites remover are generated at the same time.

The device 21 is provided with four negative ion emitting heads 211, and the negative ion emitted by the brush head 212 of each negative ion emitting head

The ion concentration is about 5 million per cubic centimeter, the ultrasonic frequency is about 40 kHz, and the magnetic field frequency is about 5 kHz.

Hive 3 and Hive 4 are used to remove mites with Dimites No. 1 contact agent. The contact agent is mixed with water to prepare a liquid, fully stirred and then put into the sprayer, and then evenly sprayed on the bee body of the hive for about 30 minutes. , the bee mites will be poisoned and drop the bee body.

Hive 5 and Hive 6 are used to remove mites with the No. 2 anti-mite paper smoke agent. After the bees return to the nest in the evening, close the nest door, then open the box cover and light the corner of the medicine bag, quickly put it into the box, and cover the box tightly. Cover, smoke for 15-20 minutes, open the nest door, and remove the residual ashes.

Hive 7 and Hive 8 use pushpins to fix the mite flaps between the bee paths to continuously remove mites.

Hive No. 9 and Hive 10 were not treated with mites, and were observed after the bee spleen hatched.

In addition, a flat plate is laid at the bottom of each beehive, and a single-sided adhesive is arranged on the flat plate, and the adhesive side of the single-sided adhesive is placed upward to facilitate the observation of collecting mites.

Since the onset time of different mites removal methods is different, especially the mite fluff tablet needs to be used for a long time to have a good effect, so the time is not a specific factor to consider in the experiment, only the time when the spleen after mites removal is completely hatched The hatching rate of the spleen and the parasitic rate of bee mites were compared. At the same time, by observing the amount of mites collected on the single-sided adhesive, the effect of mites removal can also be compared. Wherein the hatching rate of the spleen = the number of hatchlings/the total number of capped juveniles.

Table 1 Comparison of bee mites parasitism rate, spleen hatching rate and collected mites amount after removing mites from each beehive:

beehive Parasitic rate of bee mites (%) Spleen hatching rate (%) Amount of mites collected beehive one 3.2% 98.7% dense beehive two 2.5% 98.6% dense beehive three 0.3% 77.6% extremely dense beehive four 0% 67.3% extremely dense beehive five 0.8% 82.3% dense Beehive Six 1.2% 85.7% dense Beehive Seven 1.4% 92.6% dense Hive Eight 2.1% 91.2% dense Beehive Nine 39% 57.2% / Beehive Ten 36% 55.3% /

After the above experiments, the applicant found that the electronic mites remover does have the function of removing mites, and at the same time, the applicant found that most of the bee mites adhered to the single-sided adhesive were live mites that were not dead. The applicant believes that although the acaricide efficiency of the electronic acaricide is slightly lower than that of some drugs, the effect of the electronic acaricide on the honeybee is also very low, especially the spleen of the honeybee has almost no effect, making the honeybee. The hatching rate of the spleen can be maintained at a high level.

5 and 6, the applicant believes that the implementation principle of the electronic mite removal instrument may be as follows:

Because the surface of the bee 8 has fine fluff, when the bee 8 goes out to collect honey, the high-frequency expansion and contraction of the bee 8's pectoralis muscle makes the bee 8 fly by vibrating its wings 160-240 times per second, consuming energy and producing high-speed vibrations with the air. Friction in turn loses electrons and gives them a positive charge.

After the honey bee 8 returns from collecting honey, the negative ions will be emitted by the magnetic field, some of the negative ions combine with the oxygen in the air to form negative oxygen ions, and the other part exists directly as an independent body of electrons. The negative oxygen ions and electrons can interact with the bee 8. The positive charges combined to generate potential voltages, thereby generating currents on the body surface and in vivo of honey bees. Due to the small size of the bee mites 7 and their low resistance to electric current, the bee mites 7 will be stunned or numb by the electric shock, so that the bee mites 7 cannot be grasped and attached to the body surface of the bee 8, so that the bee mites 7 can be shot down. The bee mites 7 were not killed directly, but fell on the bottom of the beehive 5, so most of the mites seen on the single-sided tape were live mites. However, the body size of honey bee 8 was larger than that of bee mites 7, and the current did not affect honey bee 8.

At the same time, because the bee mites 7 are not resistant to ultrasonic waves, the bee mites 7 will crawl around under the influence of the ultrasonic waves, and then crawl out from the depths of the hive to the bee road and look for the bees 8 to parasitize. When the bee 8 is in the negative ion environment for a long time, the body surface will carry electrons. When the bee mites 7 pierce the chitin or interstitial membrane of the bee 8 and want to suck the hemolymph in the bee 8, the body surface and the body of the bee 8 are separated. A voltage difference is created, which generates an electric current to shoot down the bee mites 7 . In addition, since the hearing of the bee 8 can only hear the sound within 440 Hz, it has no sense of the high-frequency ultrasonic wave and will not be affected by the ultrasonic wave.

To further verify the effect of ultrasonic frequency on Bee mites 7.

The applicant also selected multiple beehives 5 in the same beehive for verification, and adjusted the ultrasonic frequency.

Example 1:

There are two mite removal units 2, and each mite removal unit 2 is provided with four negative ion emitting heads 211. At the same time, the concentration of negative ions released by the electric brush head 212 of each negative ion emitting head 211 is about 5 million per cubic centimeter. , the ultrasonic frequency is set to about 20kHz, the frequency of the magnetic field is about 5kHz, and the mite removal time is set to 24h.

Embodiment 2:

The difference from the first embodiment is that the ultrasonic frequency is set to about 25kHz.

Embodiment three:

The difference from the first embodiment is that the ultrasonic frequency is set to be about 30 kHz.

Embodiment 4:

The difference from the first embodiment is that the ultrasonic frequency is set to about 34kHz.

Embodiment 5:

The difference from the first embodiment is that the ultrasonic frequency is set to about 37kHz.

Embodiment 6:

The difference from the first embodiment is that the ultrasonic frequency is set to about 40 kHz.

Embodiment 7:

The difference from the first embodiment is that the ultrasonic frequency is set to about 45kHz.

Embodiment 8:

The difference from the first embodiment is that the ultrasonic frequency is set to about 50 kHz.

Embodiment 9:

The difference from the first embodiment is that the ultrasonic frequency is set to about 60 kHz.

Comparative example 1:

The difference from the first embodiment is that the ultrasonic frequency is set to about 10 kHz.

Comparative example two:

The difference from the first embodiment is that the ultrasonic frequency is set to about 15kHz.

Comparative example three:

The difference from the first embodiment is that the ultrasonic frequency is set to about 65kHz.

Comparative example four:

The difference from the first embodiment is that the ultrasonic frequency is set to be about 70 kHz.

Comparative example five:

The difference from the first embodiment is that the ultrasonic generator 22 is not provided.

Performance check:

The parasitic rate detection of bee mites is carried out to Embodiments one to nine and Comparative Examples one to five, and the detection results are as shown in the table:

The parasitic rate detection of the bee mites of table 2 embodiment one to nine and comparative examples one to five:

test Parasitic rate of bee mites (%) Example 1 3.7% Embodiment 2 3.7% Embodiment 3 2.6% Embodiment 4 2.7% Embodiment 5 3.5% Embodiment 6 2.5% Embodiment 7 2.9% Embodiment 8 2.2% Embodiment 9 4.6% Comparative Example 1 9.7% Comparative Example 2 8.6% Comparative example three 7.9% Comparative Example 4 8.2% Comparative Example 5 10.2%

As can be seen from the table, in Embodiments 1 to 9, the mite-removing efficiency of the mite-removing instrument is better than the mite-removing efficiency in Comparative Examples 1 to 5. There was no abnormal behavior of the bees.

The applicant believes that the reason why bee mites cannot tolerate the ultrasonic frequency of 20kHz-60kHz may be as follows: the ultrasonic frequency of 20kHz-60kHz is the ultrasonic frequency band used by bats for positioning, and most nocturnal insects will evolve unique hearing in order to avoid predation by bats Organs can capture the ultrasonic waves in this frequency band. Although the bee mites 7 are not insects preyed on by bats, they also have auditory organs that can hear the frequency band. As a result, if they crawl around, they will climb out of the depths of the nest and come to the bee road, which will make them more vulnerable to negative ions.

At the same time, after observing the phenomenon of mites, the applicant found that the sensitivity of different species of bee mites to ultrasonic waves in different frequency bands will also be different. The proportion of small wasp mites will be higher; while at 40kHz and 50kHz, the parasitism rate of giant bee mites will be lower, and the proportion of giant bee mites will be higher when mites are dropped.

Therefore, in order to further verify the better mite removal effect of the electronic mite removal instrument, the applicant further made the following settings:

Embodiment ten:

There are two mite removal units 2, and each mite removal unit 2 is provided with four negative ion emitting heads 211, and the concentration of negative ions released by the electric brush head 212 of each negative ion emitting head 211 is 5 million per cubic centimeter, The frequency of the magnetic field is 5 kHz, the frequencies of the ultrasonic generators 22 in the two mite removal units 2 are set to 30 kHz and 40 kHz respectively, and the mite removal time is set to 24 hours.

Embodiment eleven:

The difference from the tenth embodiment is that the frequencies of the ultrasonic generators 22 in the two mite removal units 2 are respectively set to 30 kHz and 50 kHz.

Embodiment 12:

The difference from the tenth embodiment is that the frequencies of the ultrasonic generators 22 in the two mites removal units 2 are respectively set to 34 kHz and 40 kHz.

Embodiment thirteen:

The difference from the tenth embodiment is that the frequencies of the ultrasonic generators 22 in the two mite removal units 2 are respectively set to 34 kHz and 50 kHz.

Performance check:

Embodiment ten to thirteen are carried out to detect the parasitic rate of bee mites, and the detection results are as shown in the table:

The parasitic rate detection of bee mites in the tenth to thirteenth embodiments of table 3:

It can be seen from the table that when the frequencies of the ultrasonic generators 22 in the two mite removal units 2 are set to 30 kHz and 50 kHz respectively, the two ultrasonic waves will not have a great interference effect. Compared with other frequencies, it is better. At the same time, the ultrasonic frequency of 34kHz and 40kHz can also have a better effect on large and small bee mites. At these frequencies, the effect of electronic mite removal device 6 is no worse than that of drugs. , while harmless to the spleen of bees.

The embodiment of the present application also discloses a beehive. 2 and 7, the beehive 5 includes the above-mentioned electronic mite removing instrument 6, and the electronic mite removing instrument 6 is located at the top position of the beehive 5 and the through hole 121 is set downward, and the negative ions released by the electronic mite removing instrument 6 can Go down into the bee tunnel.

In conjunction with Fig. 8, the implementation principle of a kind of beehive in the embodiment of the present application is:

The negative ions released by the electronic mite removal instrument 6 enter the beehive passage of the beehive 5 under the action of the magnetic field force, and the ultrasonic wave released by the electronic mite removal instrument 6 enters the hive to drive the bee mites 7 to the bee road to find the bees 8 to be parasitized; 5 is filled with negative ions and negative oxygen ions, and the 8 individual bees and the bee pupae 9 will also be charged with negative electricity. When the bee mites 7 pierce the chitin or interlayer of the bees 8 and want to suck the hemolymph in the bees At the same time, when the bee mite 7 pierces the surface of the bee pupae 9, a pressure difference will be generated on the body surface of the bee pupae 9 and shoot down the bee mite 7.

The shot down bee mites 7 fall to the bottom of the beehive 5, and there are only two options. Either climb out of the beehive 5 or climb up into the bee colony again; It will die naturally; and the bee mites 7 that re-climb into the bee colony will still be shot down by electric shock, and the repeated cycle will still run out of energy and die, so the beehive 5 can finally be achieved without medicine.

The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore: all equivalent changes made according to the structure, shape and principle of the present application should be covered within the scope of the present application. Inside.
