Abstract

The invention relates to agriculture and provides an increase in the productivity and efficiency of selecting cows for machine milking, as well as reducing labor costs due to the fact that the assessment is carried out during the milking of the cow simultaneously on the anatomical, morphological and physiological characteristics and their dynamics in the process of milking simultaneous assessment of mastitis and a final assessment immediately after the completion of milking. At the same time, aatomomorphological properties are established by the shadow reflection of the udder and nipples from two sides, front and bottom. A device for assessing the suitability of cows for machine milking contains a device for assessing the aatomo-morphological properties of the udder and the milking machine. The device for evaluating the udder is equipped with a fixation mechanism, LEDs that transmit electric current only from the shadow contours of the udder, and are made in the form of a box with walls having a mirror surface covered with light electrothermal paper that is sensitive to the passage of electric current when the shadow falls from the projection of the udder and nipples. The teat cups are equipped with an indicator of lactation inhibition, and the device for assessing mastitis has the appearance of a ball chamber with an inner surface of black CE1W, equipped with a sensor. Adjust the height of the device relative to the udder, brings fixture. If the lamp lights up green, the animal is suitable for machine milking, and if it is red it is unsuitable. Then put on the teat cups and give out the cow. Immediately after putting on the glasses, the milk is checked visually for mastitis. After completion of the milking, the device is moved to another animal. 5 hp f-ly, 6 ill. Yo

The invention relates to agriculture, in particular to devices for assessing the suitability of cows for machine milking.

The purpose of the invention is to increase the efficiency of selecting cows for machine milking.

yeTpoTVcfо for evaluating the suitability of cows for machine milking contains a device 1 for evaluating the morphological properties of the udder and teats, made as a box 2 with side 3. front 4 and bottom 5 walls having a mirrored surface, and located on a hinged-mounted rack B, replicating the field room, collector 7, teat cups 8 with constant diameter teat tubes 9, milk output intensity sensor 10, device 11 for estimating the udder for mastitis, made in the form of a ball chamber 12 with the inner surface black color 13 with a sensor 13, locks 14 of the hind legs of the animal, made in the form of corrugated elastic chambers 15, mechanism 16 for fixing device 1, LEDs 17, rollers 18 of rack 6, retractable tube 19, gear 20 with rail 21 and handle 22, accumulator torus 23 and rheostat 24.

Walls 3-5 of box 2 are covered with light electrical paper with test outlines of nipples and udder saturated with carbon and transmitting electric current when shadows from the udder and teats fall into it, while walls 3 and 4 are provided with a source of light 25 with adjustable illumination. The side walls 3 are installed with the possibility of tilting and, at the point of contact with the extremities of the animal, are made with an oval cutout 26, and the wall 5 is provided with a cutout 27 for the udder teats.

The device 1 is equipped with control lamps 28 green and red 29 colors (not shown). Powered by battery 23.

The teat cups 8 include a housing 30. The teat tube 9 with corrugations 31 is genuinely nipple. A tube 32 is installed in the lower part of the glass in which the ball chamber 12 of the device 11 is located, the valve 33 for inlet of milk into the chamber 12, the screen 34. In the chamber 12 a sensor 13 is installed, which dramatically reduces the resistance of the electric current when the mastite milk flows, which is transmitted to the unit 35 registrations.

In the lower part in the grinding chamber

36 cups 8 a sensor 10 of the intensity of milk excretion is connected to the registration unit 35. Podskoskov camera 36 cups 8 communicated by means of a hose 37 with a manifold 38 manifold

0 7 and further with a measuring device 39, in which the float 40 through the rod 41 and the worm gear 42 has the ability to start the stopwatch 43.

Device 1, a collector 7 with milking cups 8, an accumulator 23, a measuring device 39 are mounted on a trolley 44 moving from the stall to the stall.

The hinges 14 of the hind legs of the animal consist of two legs with corrugated chambers 15, having a rounded portion at the point of contact with the animal's legs, which is pressed against the leg under the action of pressure supplied to chambers 15 from an overpressure source.

5 (not shown).

The side walls 3 of the duct 2 are connected to depressions by projections.

The current in the circuit is controlled by the instrument. The device works as follows.

The operator lets the animal into the stall. It then opens the access of overpressure to chambers 15 of clips 14. Under the action of overpressure of chamber 15

5 expand and, in their rounded parts, fix the animal's hind legs in a certain position.

Then, after washing and rubbing the udder of the animal, the operator moves

0 fixture 1 mounted on a stand 6 with rollers 18 and by means of a handle 22, gear 20 and rail 21 fixes fixture 1 at a certain height depending on the location of the udder from the floor

5 rooms. Next, it connects the sources of light 25 to the battery 23, the brightness of which is regulated by a rheostat 24. The sources of light 25 with their heat stimulate the milk flow of the animal and are used to evaluate the morphological properties of the udder.

If the dimensions of the udder and nipples in the reflection are in the allowable area, i.e. within the control shapes on the walls of the box 2, the passing current provides for the glow of the lamp in green, which indicates the cow's suitability for machine milking based on the morphological properties of the udder and teats.

If the outlines of the udder and nipples during reflection are greater or less than the fixed outlines of the udder and nipples on the walls of duct 2, then the passing current will provide a red lamp that indicates the cow's unsuitability for machine milking due to the anatomical and morphological properties of the udder and teats .

If, as a result of the analysis, the cow's suitability for machine milking is determined by morphological properties, the operator proceeds to assess the physiological properties of the udder and teats with a preliminary assessment of mastitis. The operator puts the teat cups 8 on the nipples, opens the valve 34 and by means of the sensor 13 detects the presence of mastitis according to the indications of the registration unit 35.
