The teat cup 7 has a collector 16, which is provided with a calibrated orifice 17. Each collector 16 is attached to a bracket 18, which is pivotally connected to the shank 19.

The control unit 2 (FIG. 1) consists of four milk sensors 20, 21, 22, 23, each of which is connected by a milk hose 24 to its collector 16 and further to the teat cup 7. Each sensor 20,21,22,23 is available the milk is connected by the milk hoses 25 and 26 with the milk hose 27 of the manipulator, which is connected to the milk line 28. On the milk hose 27 of the manipulator there is a mechanical clip 29

In the case of milk detectors 20-23, floats 30 are installed with needles 31, which are made with a variable cross-section along the length. The case of each milk presence sensor 20-23 has a calibrated opening 32, a dividing wall 33, milk supply 34 and milk-withdrawing 35 nozzles. Each float 30 is connected to the plunger 36. The plunger body 37 (FIG. 3)

It has four chambers: atmospheric pressure chamber 38, constant vacuum chamber 39, atmospheric pressure chamber 40, control vacuum chamber 41.

Vacuum chamber 39 of the first vacuum

sensor 20 (Fig. 1) is connected by vacuum hoses 42 and 43 to vacuum wire 44 and vacuum hose 45 to a constant vacuum chamber 39 of a downstream sensor 21, which is connected by vacuum hose 46 to a chamber 39

constant vacuum sensor 22 and further through the vacuum hose 47 with the camera 39 of the constant vacuum of the last sensor 23.

The control vacuum chamber 41 of the first sensor 20 is connected by the vacuum hoses 48 and 43 to the vacuum hoses 48 and 43 with the vacuum wire 44, the control vacuum chamber 41 of the subsequent sensor 21 is connected by a vacuum hose 49 to the branch pipe 50

sensor 20. The vacuum control chamber 41 of the sensor 22 is connected by a vacuum hose 51 to the port 50 of the sensor 21. The control vacuum chamber 41 of the last sensor 23 is connected by a vacuum hose 52 to the branch pipe 50

sensor 22. The pipe 50 of the last sensor 23 is connected by a vacuum hose 53 to a pneumatic amplifier 54. The pipe 55 of each sensor 20-23 of milk availability is connected by a vacuum hose 56 to the mechanism 8

each teat cup 7, pneumatic amplifier 54 is connected: vacuum hose 43 to vacuum wire 44; vacuum hose 57 with pneumatic clamp 58; vacuum hose 59 with pneumatic cylinder 3; vacuum hoses 59 and

60 with pneumatic cylinder 11 output manipulator.

The pulsator 61 is connected to a vacuum wire 62 and a vacuum hose 63 with a variable vacuum distributor 64, and then through vacuum hoses 65 to the interstitial chambers of teat cups 7. A starting clip 66 is installed in the upper part of the sensor housing 20 23 of milk. Plunger 36 ( Fig. 3) is equipped with a short channel 67 and a long channel 68. The short channel 67 is connected to the nozzle 50, and the long channel 68 is connected to the nozzle 55.

The partition 33 divides the body of each sensor 20-23 of the presence of milk into chambers 69 and 70, the latter is equipped with a valve 71 with channels 72.

The manipulator works as follows.

After preparing the udder for milking, the operator sets the sensors 20-23 for milk (Fig. 1) to the starting position by lifting the plungers 36 and fixing them with the start brackets 66 Then opens the mechanical clip 29 and brings the teat cups 7 under the animal's mouth Holding the handle 5 with one hand pressing it down while raising the teat cups 7 and putting it on with the other hand, on the outgoing animal vacuum from the milk line 28 through the milk hose 27 of the manipulator, along the hoses 25 and 26 through the sensors 20,21,22 23 milk availability through the hoses 24 through the collectors 16 enters in on teat chambers of teat cups 7. Vacuum from vacuum-wire 62 through pulsator 61 through vacuum hose 63 enters distributor 64 of variable vacuum and then through vacuum hoses 65- into inter-wall chambers of teat cups 7. With the starting position of sensors 20-23 milk their plunger 36 is in the upper position. The mechanism 8 for the addition of each teat cup 7 is connected to the atmosphere via a vacuum hose 56, a branch pipe 55 (FIG. 3), a long channel 68 of the plunger 36 with an atmospheric chamber 40

Also connected to the atmosphere (Fig. 1) is the pneumatic cylinder 3, the pneumatic cylinder 11 of the manipulator output and the pneumatic clip 58 Air (Fig 3) to the short channel 67 of the plunger 36 through the vacuum hose 50 of the last milk presence sensor 23 (Fig. 1) to pneumatic amplifier 54, and further along vacuum hose 57 to pneumatic clamp 58 and vacuum hoses 59 and 60 into pneumatic cylinder 3 and pneumatic cylinder 11 of the manipulator

The milk arriving at the beginning of the milking is brought to the milk line 28 through the calibrated orifice 32 through hoses 26 and 27. With an increase in the milk flow rate, the milk does not have time to pass through the calibrated orifice 32 of the sensors 20,21,22,23 of the presence of milk and their chamber 70

they are filled with milk, which provides some rise for the floats 30. At the same time

the start bracket 66 is released from the abutment against the head 73 of the plunger 36 and under the action of gravity takes the lower position, and the milk presence sensor begins to monitor the mode of operation.

0 Most of the milk through the outlet 35 and the hose 25 enters the milk hose 27 of the manipulator, and a small part of the milk flows out through the calibrated hole 32, in which there is a bottom

5, part of the needle 31. Vertical oscillations of the float 30 together with the needle 31 ensure that the calibrated orifice 32 is not clogged. In each quarter of the udder, the lactation process takes place in different ways (according to

0 time and the amount of milk), also work sensors 20-23 milk availability of the corresponding quarters of the udder. When the milk flow rate decreases, the milk output through the nozzle 35 stops and it stops.

5 only squeezes through the calibrated orifice 32. The decrease in the intensity of milk delivery causes the float 30 to drop with the needle 31 into the calibrated orifice 32. When the intensity of the milk udder fraction decreases (up to 120 g / min), the opening of the long channel 68 (fig 4) of the plunger 36 constant vacuum and vacuum from vacuum wires 44 through vacuum hoses 43 and 42 through chamber 39

5 a constant vacuum of the milk 20 sensor 20 through the long channel 68. through the pipe 55, through the vacuum hose 56 enters the mechanism 8 for the addition of the teat cup 7.

0 Since the base of the bellows 12 (FIG. 5) is rigidly fixed to the teat cup 7, and the free end is connected rigidly with a stop 15, which is in contact with about 5 teat spaces of a quarter of the udder, by means of compression of the bellows 12, the teat cup 7 is moved downwards relative to the stop 15, i.e. There is a process of donation.

0 Each constant vacuum chamber 39 of milk 20-23 sensors is constantly connected to vacuum wire 44. Vacuum from vacuum wire 44 (Fig. 1) through vacuum hoses 43 and 42 through constant vacuum chamber 39

5 vacuum of the first milk sensor 20 through a vacuum hose 45 enters the constant vacuum chamber 39 of a subsequent milk presence sensor 21, then through a vacuum hose 46 into the constant vacuum chamber 39 of the milk availability sensor 22 and through the vacuum hose 47 into a constant chamber 39 vacuum of the last milk sensor 23, so that regardless of the position of the plunger 36 of the remaining sensors in the constant vacuum chamber 39 of each sensor, there will be a vacuum.

If, after switching on the doping mechanism 8, the intensity of the milk secretion increases, the float 30 rises and the opening of the long channel 68 (FIG. 3) leaves the constant vacuum chamber 39 and the milk presence sensor removes the discharge from the doping mechanism 8.

The thickened portion of the needle 31 exits the calibrated orifice 32, increasing its throughput. With a further decrease in the intensity of milk production (up to 120 g / min), the discharge again enters the extension mechanism 8.

With a further decrease in milk flow, the float 30 is further lowered with the plunger 36. When the milk release intensity decreases (to 50 r / Mi n, which is provided by the output variable cross section of the calibrated orifice 32), the float 30 occupies the lower position (Fig. 6), valve 71 closes the opening in the partition 33 and connects the chamber 69 with the milk sensor chamber 70 only via the channels 72 of the valve 71, Vacuum enters the chamber 70 through the channels 72 of the valve 71, through the hose 24 (figure 2) enters the collector 16V where due to A predetermined vacuum (up to 250 ml Hg) is established through a calibrated airflow orifice 17, which helps keep the teat cup 7 by a quarter of the udder.

At the same time, the opening of the long channel 68 (Fig. 6) is connected with the atmospheric chamber 38 and the air through the long channel 68 through the nozzle 55 through the vacuum hose 56 enters the mechanism 8 for adding the teat cup 7. When the float 30 is in the lower position, the opening of the short channel 67 of the plunger 36 connects to control camera 41,

The vacuum from the vacuum wire 44 (Fig. 1) through the vacuum hoses 43 and 48 enters the directing chamber 41 of the first milk sensor 20. The control chambers 41 of the milk availability sensors 20-23 are connected so that a vacuum is supplied from the nozzle 50 of the last milk availability sensor 23 only at the end of the milking of all the udder parts, i.e. The plungers 36 of the sensors 20,21,22,23 of the presence of milk will occupy the lower position (Fig. 6), regardless of the order in which they are lowered.

The vacuum from the control chamber 41 of the first sensor 20 of the presence of milk through the short channel 67 of the plunger 36 flows to the nozzle 50, and from it through the vacuum hose 49

(Fig. 1) - to the control chamber 41 of the subsequent milk presence sensor 21, then from it through the short channel 67 of the plunger 36 via the vacuum hose 51 will flow into the control chamber 41 of the milk availability sensor 22, then

0 from it through the short channel 67 of the plunger 36 through the vacuum hose 52 - to the control chamber 41 of the last sensor 23 of milk availability and through the short channel 67 of the plunger 36 to the pipe 50.

5 As soon as the last flow of the udder decreases the flow rate to 50 g / min, the vacuum from the nozzle 50 of the milk availability sensor 23 will go through the vacuum hose 53 to the pneumatic booster 54, which will work and the vacuum from the vacuum wire 44 to the vacuum hose 43 through Pulse amplifier 54 simultaneously enters:

- through the vacuum hose 57 to the pneumatic clamp 58, which is triggered and closes the handpiece torch hose 27, as a result of which the pressure in the inflow chambers of the teat cups 7 will approach the atmospheric one and the teat cups 7 will fall from the nipples into the trap 9;

0- through the pneumatic tubing 59 and 60 into the pneumatic cylinder 11 of the output of the manipulator and the withdrawal of the manipulator from under the Kirov;

-by the vacuum hose 59 into the pneumatic cylinder 3, as a result of which the pneumatic cylinder 3 at5 raises the rod 4 with the teat cups 7, thereby eliminating damage to the teat cups 7.
