Description

The utility model relates to the field of devices for determining the quality of commercial and hatching eggs of birds, for example, quails, guinea fowl, pigeons, eggs of partridges, bustards, pheasants, peacocks and other species of birds obtained from poultry farms, private farms and educational and experimental farms.

There is a known method for determining the quality of eggs [US 542953, G01N 33/08]. The method consists in determining the quality of eggs by transilluminating them with a narrow beam of light directed perpendicular to the major axis of the egg, while recording the value of the light beam is carried out in two areas corresponding to the upper and lower zones of the white, separated by the yolk, followed by converting the obtained values into electric current signals about the position The yolk is judged by the ratio of the received signals.

The disadvantages of this method are that it is mainly used to determine the suitability of large hatching eggs of chickens, geese, and ducks for laying, which is not suitable for studying small eggs of quails, pigeons, pheasants, partridges, and guinea fowl. The device uses photosensitive elements, clamps and a device for determining the size of the yolk of eggs, which not only requires additional financial costs, but also complicates the installation of eggs for ovoscopy.

An ovoscope is known [RU 2155959, G01N 33/08, A01K 43/00], made in the form factor of a portable compact design. The case, measuring 360×190×55 mm, is made of a detachable lid with cells for shining through 20 eggs arranged in rows, a tray with a built-in light source in the form of incandescent electric lamps, operating in constant mode 1.5-2.4 V, 0.1- 0.12 A, which have reduced dimensions compared to 220 V AC incandescent lamps. The presence of metal foil on the inner surface of the walls of the cover and sections of its horizontal plane located between the cells.

The disadvantage of this device is that it is intended only for determining the quality of larger eggs of geese, ducks, chickens and is not suitable for examining small-sized eggs of quails, pigeons, pheasants, and guinea fowl.

An ovoscope is known [RU 17368, G01N 33/08, A01K 43/00], containing a light source in the form of an incandescent electric lamp located in a housing on which there are hollow cells for controlled eggs. The design of the ovoscope is equipped with a partition, a switch and a bottom. The light source is equipped with at least one additional incandescent electric lamp, which are installed on the walls of the ovoscope body. The partition is located between the horizontal wall of the housing with cells and the light source, is installed with the ability to move along the horizontal wall of the housing with cells and is oriented parallel to said housing wall. The switch is made of a contact type, for example, a push-button type, placed on the housing and connected in series with the light source, while a slot is made on the housing.

The disadvantage of this device is that it is quite large in size and is intended only for chicken eggs.

The closest in technical essence to the claimed utility model is the ovoscope for assessing the quality of eggs of various bird species [RU 2693096, G01N 33/08, A01K 43/00]. The cylindrical body of the ovoscope measuring 222x126 mm is made of powder-coated steel, 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 device cover. The set includes a lid for candling 11 eggs from chickens and ducks, 13 eggs from quails and partridges and 5 geese eggs. In the center of each ovoscope cover there is a hollow cell with a 15 mm measuring template for eggs of chickens and geese, and 10 mm for eggs of small birds. The measuring template allows you to determine the freshness category of eggs: dietary or table.

Inside the body of the ovoscope there is a socket 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 presented ovoscope is the horizontal position of the eggs when assessing them. When using this ovoscope, you can only assess the integrity of the shell, and then only with a spindle-shaped rotation of each egg in the cell of the lid. And this increases the labor intensity and time spent on evaluating eggs. In addition, standard cells in the lid of the ovoscope do not take into account the size of the eggs, which for chicken food eggs can range from 35 to 80 g or more. The same can be said about the mass of eggs of other bird species. This leads, even with the diffuser installed, to a negative effect on the eyes of the person working with the ovoscope.

The purpose of the presented utility model is to simplify the design when assessing the quality of food and hatching eggs of a small mass of quails, pigeons, pheasants, guinea fowl, bustards, partridges, and reduce economic and labor costs.

The problem is solved by using a directed beam of a light source through an oval-shaped hole with a rubber liner with rounded edges on the outside of the lid, which allows the egg to be assessed in three projections.

The problem is solved due to the fact that the ovoscope for candling eggs of low mass of different types of poultry consists of a body with a lid and a light source. The cylindrical body is made of plastic - polypropylene or polyvinyl chloride, the upper part of which is closed by a removable lid, in the center of which there is a round hole with a rubber liner with rounded edges on the outside of the lid. An electric socket with an LED lamp and a power source is mounted in the central part of the base of the housing. At the bottom of the case there are six round holes located at the same height and distance from each other. The base of the case is rigidly fixed to a round platform made of dense rubberized material. Directing a beam of light onto a small hole in the lid allows for better transparency of the egg, even with a dark, spotted shell. The device allows you to detect egg defects: cracks, notches, small and large spots, dryness, inclusions of various etiologies, pouring; determine the qualitative characteristics of eggs - the location and condition of the air chamber, the position and mobility of the yolk, the density of the albumen, and during incubation the fertilization of the eggs, the category of embryo development and incubation waste.

New significant features:

1. Cylindrical body, made of plastic - polypropylene or polyvinyl chloride;

2. The upper part of the case is closed with a removable lid, in the center of which there is a round hole with a rubber liner, which has rounded edges on the outside of the lid;

3. An electric socket with an LED lamp and a power source is mounted in the central part of the base of the housing;

4. At the bottom of the case there are six round holes located at the same height and distance from each other;

5. The base of the case is rigidly fixed to a round platform made of dense rubberized material.

The listed new essential features, in combination with the known ones, make it possible to obtain a technical result in all cases covered by the scope of legal protection.

Technical result

The technical result is that the device allows for a comprehensive assessment of the morphological parameters of the egg: height and diameter of the air chamber, yolk mobility, protein quality, marbling, shell integrity, presence of inclusions in the egg, category of embryo development, fertilization, categories of egg waste during incubation with a high level of biological reliability of both food and hatching eggs, analyze eggs in a wide range of masses from 6 to 80 g, and also has simple design features and ease of use.

In fig. Figure 2 schematically shows the assembled body of the ovoscope - side view;

In fig. Figure 3 schematically shows the ovoscope body without a cover with an LED lamp - top view.

The ovoscope consists of a cylindrical body 1 made of plastic, for example, polypropylene or polyvinyl chloride. The upper part of the body is closed by a removable cover 2, in the center of which there is a hollow round hole 3 (Fig. 1) with a rubber liner 4, and in the lower part of the body 1 there are six round holes 5 located at the same height and distance from each other. The presence of round holes 5 on the body 1 prevents overheating of the inside of the device. The base of the housing 1 is rigidly attached to a round platform 6 made of dense rubberized material (Fig. 2). An electric socket with an LED lamp 7 (Fig. 3) and a power supply from the network (not indicated in the Fig.) is mounted inside the body of the ovoscope.

The ovoscope is designed for candling eggs of different sizes. When working on an ovoscope for candling eggs of small masses of different types of poultry, it should be taken into account that candling of eggs can be done by placing the egg vertically with a sharp pole or by placing the egg horizontally on the rubber liner of the lid. Candling eggs in a vertical position makes it possible to determine the position and size of the air chamber, pigmentation of the yolk on an intact egg, the intensity of embryo development on control days, egg shrinkage during incubation based on the size of the air chamber and incubation waste: infertility, drying out, blood ring. Candling eggs in a horizontal position helps determine the integrity of the shell, its marbling, the position of the air chamber, the intensity of embryo development, and the readiness of the chicks to hatch.

For ease of operation, eggs in a container or lumpy spacer intended to be visible through the ovoscope should be placed to the right of the ovoscope or in front of it.

After turning on the ovoscope, you should wait 3-5 minutes for the LED lamp to heat up; Take an egg of any type of bird with your right hand and place it with the sharp pole down. Due to the directional beam from the light source, the egg will be illuminated from bottom to top, regardless of the pigmentation and thickness of the shell, and the small hole in the rubber insert will not allow the egg to fall inside the ovoscope. If necessary, the egg is placed from a vertical position with the right hand into a horizontal position and scrolled by hand around the length of the axis of the egg.
