State of the art

An invention is known (see ed. mon. RU No. 2693096, class G01N 33/08, A01K 43/00, 2018) an ovoscope for assessing the quality of eggs of various bird species. The body of the ovoscope is made of steel with a powder coating, cylindrical shape, the surface of the body is made in the form of a removable cover. Hollow oval cells are made symmetrically in a circle on the surface of the cover of the device. Inside the body of the ovoscope, a cartridge is mounted for installing an LED lamp, with a power source from the mains or a battery built into the lamp. Three housing supports made of rubberized material are attached to the housing tray.

The disadvantage of the device is that the device is designed to study ten eggs at the same time, which must be brought to the cells, which requires additional time to install and determine the quality of a large batch of eggs. The device device is stationary, which also reduces the mobility of the device.

The closest in technical essence and the achieved positive result, adopted by the authors as a prototype, is an ovoscope (see ed. certificate RU 2020480 C1, class G01N 33/08, A01K 43/00 1990), related to agriculture, in particular to breeding birds in domestic and industrial conditions. This ovoscope differs in that it contains a casing, a tube, a lamp and a mirror with an installed wire rod, which at one end is connected to the protruding segment of the tube, the other is fixed to the upper edge of the concave mirror, which is mounted on an axis and spring-loaded with the possibility of a small movement limited by the stroke of the rod. A microswitch is installed inside the ovoscope, shunted by a rectifier element (semiconductor diode) and connected in series to the electric circuit of the lamp. In the side surfaces of the tube on opposite sides there are slots for installing light filters.

The disadvantage of the device is that the device is designed to study one egg, which must be brought to a tube with replaceable filters, which requires additional time to install and determine the quality of a large batch of eggs. The device device is stationary, which also reduces the mobility of the device.

Utility Model Disclosure

The objective of the proposed utility model is to detect egg defects, determine qualitative characteristics, assess the development of the embryo during incubation of eggs without removing the eggs from the incubation trays, which can significantly reduce the time spent by the incubation eggs outside the incubator.

The technical result that can be achieved with the proposed utility model is reduced time for the study of hatching eggs, better analysis and mobility of the proposed device, due to the small form of the proposed device.

The technical result is achieved using an ovoscope for assessing the quality of hatching eggs of birds, including a body, a mirror, a lamp, and additionally contains a cylindrical body made of heat-resistant plastic, divided into vertical and horizontal parts, while a fixed cover is attached to the vertical part of the body with a round hole with a diameter of 10 mm and a rubberized edge, a switch is also built into the vertical part of the case, a concave mirror, which is located behind the cartridge with an LED lamp installed in it, and the cartridge is connected to a power source from a 220 volt variable network by a supply wire.

Implementation of the utility model

A study using the device is carried out by the method of transillumination of eggs using a light source. The device allows you to detect egg defects (cracks, small and large spots, dryness, inclusions, pouring, etc.), determine the qualitative characteristics of eggs (the state of the air chamber, the position and mobility of the yolk), determine the freshness of eggs by the height of the air chamber, and also evaluate the development embryo during egg incubation.

The ovoscope is presented in the form of drawings (see Fig. 1, Fig. 2, Fig. 3).

The body of the ovoscope 1 (see Fig. 1) is made of heat-resistant plastic, cylindrical in shape, a fixed cover 2 is attached to the vertical part of the body (see Fig. 1) with a round hole 3 with a diameter of 10 mm (see Fig. 1) with a rubberized edge , which is brought to the wall of the hatching egg 4 (see Fig. 1). A switch 5 is built into the vertical part of the ovoscope body (see Fig. 1, Fig. 2, Fig. 3), a concave mirror 6 (see Fig. 1) located in the vertical part of the body behind the cartridge 7 (see Fig. 1) in in which the LED lamp 8 is installed (see Fig. 1, Fig. 2, Fig. 3), while the cartridge is connected to a power source from a variable network of 220 volts with a supply wire 9 (see Fig. 1).

The body of the ovoscope 1 consists of a horizontal cylindrical part 185×25 mm in size and a vertical cylindrical part 85×40 mm, made of heat-resistant plastic 1 (see Fig. 1), which ensures the lightness and strength of the device and ease of use and mechanical cleaning, disinfection processing, fixed cover 2 (see Fig. 1) size 30×43 mm with a round hole with a diameter of 10 mm 3 (see Fig. 1) with a rubberized edge.

The advantage of 8 LED lamps is that they consume little electricity, so they do not get hot, unlike incandescent electric lamps, they are economical. 8 LED lamps do not burst or crack, safe for human health. The advantage of LED lamps is that they give as close to natural light as possible.

To prevent damage to the egg wall (shell), hole 3 (see Fig. 1) of the cover 2 (see Fig. 1) has a rubberized edge, which reduces the likelihood of damage to the egg wall (shell) during operation.

Installing a concave mirror 6 (see Fig. 1) in the body of the ovoscope 1 (see Fig. 1) contributes to the concentration of the light beam, providing a qualitative study of hatching eggs.

Ovoscope works as follows.

The device is connected to a DC power supply, when the switch 5 (see Fig. 1, see Fig. 2, see Fig. 3) built into the vertical part of the housing 1 (see Fig. 1) of the ovoscope is switched off (see Fig. 1). Fig. 2) in the on state (see Fig. 3), the supply wire 9 (see Fig. 1) supplies power to the LED lamp 8 (see Fig. 1, see Fig. 2, see Fig. 3 ) installed in cartridge 7 (see Fig. 1). The luminous flux of the LED lamp 8 (see Fig. 1, see Fig. 2, see Fig. 3) is reflected from the concave mirror 6 (see Fig. 1), passes through the fixed cover 2 (see Fig. 1) with a round hole with a diameter of 10 mm 3 (see Fig. 1) with a rubberized edge, which is brought to the wall (shell) of the incubation egg 4 (see Fig. 1) in order to determine the qualitative characteristics of the eggs, the presence of damage, and also to assess the development of the embryo during egg incubation.

The ovoscope model proposed by us is used to control the quality of bird eggs of various species used by the population at home and by specialists in production conditions, in order to increase efficiency in determining the quality characteristics of eggs, egg defects, as well as assessing the development of the embryo during egg incubation.

The peculiarity of the device lies in the fact that the ovoscope can be used in subsidiary farms and industrial hatcheries to study biological characteristics, determine the quality of bird eggs (hens, ducks, geese, quails, etc.) in order to determine the quality characteristics of eggs, egg defects, as well as assess embryonic development during egg incubation. The mobility of the device allows you to speed up the work on assessing the quality characteristics of eggs, egg defects, as well.
