Description

The utility model relates to agriculture, in particular to milking machines and is intended for the mechanization of milking cows.

Known single-chamber milking cup [RU 2014780 C1, A01J 5/06 (1990.01), 06/30/1994] containing a housing, a rubber suction cup with ribs and petals connecting the elliptical part of the suction cup to the ring.

The disadvantages of this glass: the difficulty of manufacturing a suction cup, the need to make various sizes of glasses for animals with different diameters of the teats of the udder.

Known milking machine [RU 2250605 C1, A01J 5/00 (2000.01), 04/02/2004] containing single-chamber milking cups with pneumatic valves made in the form of a variable vacuum chamber separated by a flexible membrane connected to a pulsator pipe and a variable atmospheric pressure chamber connected with a suction cup for milking cups; In the chamber of variable atmospheric pressure, a valve is made, connected by means of a rod to the membrane.

Also known is a milking machine [RU 2263443 C1, A01J 5/04 (2000.01), 05/28/2004] containing single-chamber milking cups, a pulsator and a collector.

The disadvantage of these milking machines is the need to use different milking cups for cows with different diameters of the teats of the udder.

Known milking machine [RU 2193305 C2, A01J 5/00 (2000.01), 02/23/2000], containing single-chamber milking cups, a collector, a vacuum regulator and a pulsator.

The disadvantages of this milking machine: the need to use different milking cups for cows with different diameters of the nipples of the udder, the lack of air inlet into the suction cup of the cup for quick evacuation of milk.

The objective of the utility model is to increase the efficiency of milking cows.

This is achieved by the fact that the milking cup contains a housing, a suction cup, limiters, reed switches and magnets; the limiters are made in the form of two half rings, one of which is equipped with a protrusion, the second groove, and the protrusion of one limiter is installed in the groove of the other limiter with the possibility of movement. On the limiters, magnets are installed that have the ability to contact with reed switches located on the body of the glass. The stops are fixed inside the housing by means of rods. The pressure of the stops against the nipple is ensured by springs located on the rods, and the stiffness of the springs can be changed by setting the shims.

The proposed utility model will be clear from the following description and the attached drawings.

In FIG. 1 presents a milking cup; in FIG. 2 shows a section AA of the teat cup in FIG. one; in FIG. 3 is a view A of FIG. 2.

The milking cup (Fig. 1) is made in the form of a housing 1, the upper part of which is equipped with a rubber suction cup 2 with a protrusion 3. The lower part of the cup, located under the teat of the udder 4, is equipped with a suction cup 5. The suction cup 5 is equipped with a milk outlet 6 connected to the collector (not shown in the diagram), and a fitting 7 with an air pipe 8, which in turn is connected to one part of a half-wave pulsator (not shown in the diagram).

Inside the housing 1 on the rods 9 are limiters 10 and 11 (Fig. 1, Fig. 2), made in the form of two half rings. The limiter 10 is provided with a groove 12 (Fig. 3), and the limiter 11 is equipped with a protrusion 13. The protrusion 13 of the limiter 11 is mounted in the groove 12 of the limiter 10 with the possibility of movement.

The stops 10 and 11 (Fig. 1) are equipped with magnets 14 and 15. The case of the milking cup 1 is equipped with reed switches 16 and 17, located at the same level with the magnets 14 and 15.

Between the housing of the milking cup 1 on the rods 9 springs 18 are placed, with the possibility of changing their stiffness by installing shims 19.

A milking cup works as follows. Vacuum pressure is applied to the milk outlet pipe 6 (Fig. 1), and, therefore, to the suction cup 5 from the collector. In this case, the same value of the vacuum pressure from the pulsator through the air pipe 8 and the nozzle 7 is also served in the suction chamber 5.

An electric current is supplied to the reed switches 16 and 17 (FIG. 1 and FIG. 2). As a result of the electric current, the magnets 14 and 15 are attracted, rigidly fixed to the stops 10 and 11. This leads to the fact that the stops 10 and 11 overcome the force of the springs 18 and separate - the protrusion 13 will move in the groove 12 (Fig. 3).

Next, the operator puts the milking cup on the nipple of the udder 4 (Fig. 1), the supply of electric current to the reed switches 16 and 17 is stopped and the stops 10 and 11 are closed by the action of the springs 18, covering the nipple of the udder 4.

Begin the milking process. During the suction stroke, a vacuum gauge pressure of nominal value (for example, 48 kPa) from the collector through the milk outlet 6 and from the pulsator through the air pipe 8 and the nozzle 7 penetrates into the suction cup 5. At the same time, the nipple sphincter 4 opens, milk is removed from the udder and transported through the milk outlet pipe 6 to the collector and then to the milk receptacle.

When changing cycles in a half-wave pulsator through the air pipe 8 and the nozzle 7, atmospheric air enters the suction chamber 5, reducing the vacuum pressure in it to a minimum value (for example, 33 kPa), the “rest” cycle sets in.

The atmospheric air coming through the air pipe 8 and the nozzle 7 contributes to a more rapid evacuation of milk from the suction cup 5 to the milk outlet 6. The process is then repeated.

Changing the stiffness of the springs 18 with the help of adjusting washers 19 regulate the pressing force of the stops 10 and 11 to the nipple 4.

During operation, the protrusion 3 on the suction cup 2 prevents the milking cup from crawling onto the teat of the udder 4.

Upon completion of milking, an electric current is supplied to the reed switches 16 and 17 (Fig. 1 and Fig. 2), causing the magnets 14 and 15 to be attracted. This leads to the fact that the stops 10 and 11 overcome the force of the springs 18 and diverge - the protrusion 13 moves in the groove 12 (Fig. 3). The operator removes the teatcup from the teat of the udder.

Using a teatcup without nipple rubber allows you to increase the efficiency of milking cows, milk production and reduce the incidence of mastitis in cows udders.
