The invention relates to agriculture, in particular to milking machines,

A pneumatic pulser of a milking machine is known, consisting of three channels connected to each other by pulsators, with a sliding saddle of one of them carries out an asynchronous mode of operation, moreover, it is possible to change the duration of the massage stroke in one of the pulsators. Disadvantage

 is the complexity of the design.

A start-up collector of a milking machine is known, which increases the completeness of expelling all shares of the udder with an additional throttle channel communicating the working chamber of the alternating vacuum with the atmosphere. The disadvantage is the complexity of the design, the lack of the ability to provide asynchronous operation, and the duration of the massage in one of the half of the udder.

A device is also known consisting of two pulsators interconnected by channels with throttles installed in them. The disadvantage is the design complexity, the inability to change the duration of the massage stroke in one of the pulsators in relation to the other.

A prototype is a milking machine comprising primary and secondary pulsators, a collector and teat cups. An additional pulsator controls the air inlet into the interstitial chamber of the teat cups in order to increase the efficiency of milking by adjusting the pressure in the interstitial chamber (4). The disadvantage is the lack of asynchronous operation of the milking machine, the ability to throttle the air inlet into the interstitial chamber of one of the pairs of milking cups. The presence of a complex design means that the main pulsator only controls the operation of an additional pulsator, which ensures the synchronous operability of the four teat cups, thereby not ensuring sufficient efficiency of the milking process.

The purpose of the invention is to increase the effectiveness of milking by simultaneously ending the removal of milk from both halves of the udder and simplifying the design.

The essence of the invention lies in the fact that this goal is achieved by the fact that the chamber of the alternating vacuum of the main pulsator is connected to the control chamber of the additional pulsator having a channel for supplying atmosphere to its chamber of variable vacuum, the passage cross section of which is much smaller than

logical in the main pulsator. At the same time, it is possible to change the duration of the massage stroke of the additional pulsator by changing the cross section of the channel for supplying the atmosphere to the alternating vacuum chamber of the additional pulsator depending on the amount of milk contained in one or another half of the udder.

In the inventive device for milking animals, an alternating vacuum chamber of the main pulsator is in communication with a control chamber of the additional pulsator, wherein the cross section of the nozzle for supplying the atmosphere of the additional pulsator is smaller than the same section of the nozzle of the main pulsator, and the nozzle for supplying the atmosphere for additional withdrawal milk from both halves of the udder by changing the duration of the massage stroke in an additional pulsator.

The drawing shows a schematic diagram of a device for milking animals.

The device for milking animals consists of the main and additional pulsators having constant vacuum chambers 2, 7, membranes 16 of them 17, valves 15

and 18, control chambers 1 and 8, variable vacuum chambers 3 and 5, channels 4 and 6 for supplying atmosphere, nozzles 11 and 12, chokes 13 and 19, connecting tube 20, constant vacuum nozzle 9, nozzles

alternating vacuum 10 and 14.

The constant vacuum chamber 2 is separated from the control chamber 1 by a membrane 17 connected to a valve 18 located in the variable vacuum chamber 3 having nozzles 4 and 11. The nozzle 10 communicates with the control chamber 1 by means of a connecting tube 20 and a throttle 19. Camera 7, the constant vacuum is separated from the control chamber 8 by means of a membrane 16 connected to the valve 15 located in the chamber of the variable vacuum 5, having a pipe 4 of variable vacuum, a pipe 12 with a channel 6 for supplying atmospheric or overpressure having another ass 13.

A device for milking animals works as follows.

When creating a vacuum in the constant vacuum nozzle 9, the constant vacuum chamber 2 and 7, the valves will block the atmosphere supply channel 4 and 6 due to the atmospheric pressure of the control chambers 1 and 8, which moves the membranes 16 and 17 connected to the valves 15 and 18. В cameras

alternating vacuum 3 and 5 creates a vacuum

and there is a sucking beat. Vacuum is also created in the tube 20 of the nozzle 10, throttled by the throttle 19 and occurs in the control chamber 1. Atmospheric pressure, acting on the valves 18 through the channel 4 moves it, pressing the constant pressure chamber 2 to the seat, and an atmospheric working chamber 3 forms atmospheric the pressure that enters through the connecting tube into the control chamber 8. In the pipe 10, a mass soot stroke occurs. Gradually, atmospheric pressure penetrates through the connecting pipe 20, the throttle 19 into the control chamber 1, where, acting on the membrane 17, moves the valve 18 to the pipe 11, blocking the channel 4, which prevents the atmosphere from entering the chamber of the alternating vacuum 3, where it starts. the suction stroke, as it communicates with the constant vacuum chamber 2. Since the variable vacuum chamber 3 is connected by a connecting channel to the control chamber 8, a vacuum is created therein. Under the influence of atmospheric pressure, Formula 1, An animal milking device comprising a primary and secondary pulsator, each of which has an alternating vacuum chamber communicating through the nozzle with the atmosphere, controlling and constant vacuum chamber, characterized in that, in order to increase the efficiency of milking by at the same time ending the removal of milk from both halves of the udder and simplifying the design of the can, acting on the valve 15 through the pipe 12 and channel b, the valve 15 moves and disconnects the camera vacuum 5 from the constant vacuum chamber 7. V

chamber 5 begins to occur massage stroke. However, since the passage section of the nozzle 12 is much smaller than the passage section of the nozzle 11, the transition process from the sucking stroke to the massage stroke will take a longer

0 time span. The throttle 13 can change the time of filling the chamber of the variable vacuum 5 with air, which contributes to a change in the duration of the massage stroke, and this in turn affects

5 ratio of measures. In this way, the necessary clock ratio can be achieved depending on the productivity of one or another half of the udder.

The animal milking device operates asynchronously.

This makes it possible to provide a more adequate milk removal process and reduce the likelihood of an udder disease.

A measure of the alternating vacuum of the main pulsator is communicated with the control chamber of the additional pulsator, while the cross section of the pipe for communication with the atmosphere of the additional pulsator is made smaller than the same section of the pipe of the main pulsator.

2. The device according to claim 1, characterized in that the pipe for communication with the atmosphere of the additional pulsator is equipped with a throttle.
