Description

The invention relates to beekeeping, in particular to the collection of bees.

The purpose of the invention is to increase the collection of yes.

Figure 1 shows a device, a longitudinal section; figure 2 is a section aa in figure 1.

The device contains the following items. In the frame space ul 1 with honeycomb frames 2, instead of the ceilings of ul, a diaphragm 3 is installed, which is a flat electrode made in the form of a dielectric plate with a metal layer 4 (copper foil) deposited on its lower surface, the surface of which is insulated with a thin layer of a mixture of dielectric material, e.g. insulating varnish (not shown). Layer 4 is connected to the high voltage terminal 5 of the high voltage generator b, the low potential terminal of the generator 6 is grounded. In the diaphragm 3, holes 7 are made, communicating the volume of ul 1 with the volume of the extension 8 mounted above the diaphragm 3. The openings 7 of the diaphragm 3 are closed by a shutter 9, made, for example, in the form of a piece of cloth (canvas). To remove the shutter 9 from the openings 7, a slot-like opening (not shown) is provided in one of the side walls of the extension 8. The dimensions of this hole were chosen so as to be able to simply remove the shutter 9 from the holes 7, but at the same time not to allow the bees to leave the extension body 8.

On the protrusions (folds) of the side walls of the extension 8, prefabricated frames 10 with wire electrodes 11 and successors 12 are suspended. Each of the additional reception frames (see figure 2) is made in the form of a frame 13, two transverse trims 14 and 15, on top of which are odd and even parallel rows of wire electrodes 11, two additional receivers 12 — two glass plates — are inserted into two gaps between the electrodes 11 and the frame 13. The wire electrodes 11 have two independent terminals 16 and 17. Terminal 16 is the output of odd rows of wire electrodes 11, and terminal 17 is the output of even rows of electrodes 11. Terminal 16 is in electrical contact with a metal bus 18 mounted on one of lateral protrusions of extension 8, terminal 17 is in electrical contact with a metal bus 19 mounted on another lateral protrusion of extension 8. Bus 19 is electrically connected to potential terminal 20 of the bee current irritation generator 21,

and bus 18 with a grounded terminal 22 of the generator 21.

The sections of wire electrodes 11 in contact with the strips 14 and 15 (areas not under the additional receivers 12) are coated with dielectric material, for example, non-conductive varnish, to avoid losses and on the strips 14 and 15. The extension 8 is closed by a lid

23, for which a glass plate can be used to monitor the behavior of bees during a sampling session.

In two gaps between the receivers 12

and with wire electrodes 11 of the accessory frame 10, a coating (not shown) can be introduced that is permeable to the sting of the bee and does not injure it when the additional receiver 12 is removed.

With the device they work as follows.

In the daytime or in the evening, a diaphragm 3 with a shutter 9 and an extension 8 with additional frames 10 are installed in the hive 1 (it is possible to install an extension 8 with frames 10 immediately before collecting yes). A selection session is carried out early in the morning of the next day. Just before turning on the electronic units 16 and

21 provide the bees access to the wire electrodes 11 of the prefabricated frames 10 by removing the shutter 9 from the openings 7 of the diaphragm 3, thereby communicating the volumes of the ul 1 and extension 8. The bees' motor activity is excited in two stages. At the first stage, the high-voltage generator 6 is turned on, supplying the full high-voltage voltage to the flat electrode 3, which provides the bee family with an electric field with an EL voltage acting between the high-voltage electrode 3 and the Earth's surface. The indicated electric field, acting in the entire volume of the ul, activates the bees located in their nest. The bees rush into the installation zone of the diaphragm 3, pass through the holes 7 and fall on the collecting frames 10. When the generator 21 is turned on, an electric voltage acts between the odd and even rows of wire electrodes 11, forcing the bees to sting the receivers 12. When enough bees accumulate in the volume of the extension 8 (this occurs after several minutes of operation of the generator 6, turned on at full voltage), the second stage of excitation of the motor activity of bees begins, at which it is possible to reduce the high voltage e supplied to the electrode 3. When

In this case, the bees are excited in the volume of the extension 8 by an electric field with a voltage E2 acting between the high-voltage electrode 3 and the wire electrodes 11 of all collection frames 10 connected to the zero potential either directly or through the elements of the electronic circuit of the generator 21. Since the distance between electrode 3 and electrodes 11 is much smaller than the distance between the electrode 3 and the Earth’s surface, then to obtain a field strength equal to the field strength EI, a significantly lower value of high about the voltage supplied to the electrode 3 and, therefore, a significantly lower amount of energy is needed to power the unit 6.

After the selection session is over, remove the cover 23 of the extension 8, remove the additional frames 10 from the extension, the line (or estimate) of the remaining 10 bees in the extension 8, after which the extension 8 is closed again with the cover 23. After some time, the bees from the extension 8

gradually go into their nest and calm down, after which it is possible to remove the extension 8, the diaphragm 3 and close the supra-frame space of ul 1 with its halves and

the lid.
