The invention relates to agriculture, in particular to devices for controlling the milking process.

The purpose of the invention is to keep the teat cups on the udder after completing the lactation and to eliminate the negative impact of the vacuum on the outflow, improve the evacuation of the milk from the float chamber and flush out the outlet nozzle.

FIG. 1 schematically shows a milking process control device during milking in the sucking stroke; in fig. 2 - the same, when milking in the compression stroke; in fig. 3 - the same, at the end of the milking; in fig. 4 - part of the outlet nozzle with overlapped calibrated hole when milking tugoyyny cows; in fig. 5- part of the device with the milk line with the sheath, the connecting element; in fig. 6 - the same, when milking two rows of arranged cows with separated connecting elements.

The milking process control unit contains a milk volume sensor having a float chamber 1 inside which there is a float 2, having a needle 3 at the bottom, the end of which enters the calibrated orifice 4. A stem 5 connected to the spool 6 of the spool switch, which can move, is attached to the float. In the housing 7, comprising fittings 8 and 9. The spool 6 extends beyond the limits of the housing 7 and at its end there is a head 10 interacting with a latch 11, 1 of the hinge fixed to the housing 7. On the shaft 5 a valve 12 is fixed, having conductive opportunity to overlap the end 13 of conduit 14, the other end of which is connected to the collector 15 of the milking machine. In the milk chamber of the collector there is a tap 16. The nozzles 17 connect the teat chamber 18 of the teat cup 19, the interwall chamber 20 of which is connected to the pulsator with the hose 21. The pulsator is combined with the pulsator collector in one housing 22 and has chambers of constant 23 and 24 vacuum and control chamber 25. The pulse amplifier has a control chamber 26, which is connected to pipe 9 of the spool switch by pipeline 27, and an alternating vacuum chamber 28. The connector 8 of this switch is connected by pipe 29 to the switch vacuum pulsator.

At the bottom of the float chamber below the calibrated orifice there is a Hutus 30, connected 1) with an () bottom pipe 31, in the lower part of the case) there is a caliber | 1 () 1 an opening 32. At the outlet nozzle 31 is seton. named fjatel 33, having a stopper 34 for closing the opening 32. To prevent the opening from completely closing, the seat 35 under the stopper 34 has a groove 36. Naz may be

made on the cork, and the seat can be smooth. A reduction in the cross section of the calibrated orifice 21 is necessary for milking the bearded cow. The upper part of the float chamber 1 is connected by a pipe 37 with the evacuated milk line 38. A discharge pipe 31 is also connected to the milk line by means of the hose 39. The vacuum line 40 is connected to the chamber 23 by a pipe 41

0 constant vacuum of the pulsator and the chamber 42 of the constant vacuum of the pulsous amplifier. A connecting element 43 is used to secure the portable device to the stationary milk line.

from two sensors you can use the connecting element 44.

The device works as follows.

Before the start of milking to p with two

the apparatus enters the joint between two

cows, attaches a milk volume sensor to the milk vacuum pipes. and at the same time, the pulsator begins to pulsate, but no signals are transmitted to the pulsator as the bypass in the spool is closed. The pod prepares the cows and a milking machine is installed on them. To do this, it raises the spool 10 with the valve and the float by the head and sets it on the latch 11. The pulsator transmits the pulsations to the control chamber 26 via pipes 29 and 27 and the spool channel.

Q pulsoal, which respectively connects the interbed wall of dimension 20 of the teat cup 19 through channel 21 and 41 to the vacuum wire 40. The suction and compression strokes occur and milking begins. Connecting the ripple amplifier between

- a pulsator and a teat cup improves the operation of the milking machine and provides faster milk output and cleaner cow delivery. Further, the milk from the collector 15 through the pipeline 14 through the outlet end 13 enters the pop-up chamber 1 and fills it with milk. The float 2 floats and lifts the spool 6 with the head 10, freeing the slide 11, which falls down under its own weight. Milk through pipe water 37 enters directly into the milk conduit 38. At the same time, a small fraction of the milk goes through the calibrated orifice 4 to the outlet nozzle 31 and further along channel 39 to the milk conduit.

The air entering through the calibrated hole 32 facilitates the movement of the MOviOK to the milk line 38. The calibrated hole 32 is blocked by the stopper 34 to feed the cows, then the air enters only through the side groove 36, the cross section of which is smaller than the main hole 32, therefore the final feeding phase occurs more slowly and tightly cows are better given out. At the end of the meal, the milk supply decreases.

the float chamber 1 and then the milk will expire only through the calibrated orifice 4 and the outlet nozzle 31. The float 2 is lowered and atmospheric air enters the control chamber 26 of the pulsous booster through the upper channel of the spool and the choke 9. The teat rubber stops pulsing and shrinks, eliminating the collapse of the apparatus from the cow's udder.

In this case, the lower plane of the valve .12 blocks the outlet opening of the end 13 of the pipeline 14 and the weight of the valve, spool, float and atmospheric pressure acting on the end of the spool presses the valve 12 against the end of the pipeline with a certain force.

Thus, depending on the total mass of the listed components, the magnitude of the vacuum in the pipe 14, the collector 15 and the teat box 18 of the teat cup depends, as it is on the equilibrium of the vacuum amount, the milk volume sensor and the vacuum in the pad room, where the constant air leakage through the collector is influenced by the mass acting on valve 12. In this case, noc.ii,: and; 1 is in the floating (ajar) position and aspirate from the manifold and the inflow chamber: - with excess air, which reduces the level of Akum in the collector and, respectively, in the spouting chambers of teat cups, eliminating the harmful effects of a vacuum on a cow. The float chamber 1 is freed from milk and a transparent float is visible through the transparent chamber stalk, which is visual l i. ; v: on the termination of milk cow.

Checking the purity of the cow and closing the valve 16 on the collector 15, before p removes the milking machine from the cow's udder. After the completion of the milking of the cows by both adjacently arranged apparatuses

The rams do-p simultaneously disconnects them from the milk line and moves them further, between the next pair of cows. Compared with the known systems of milk lines, the transfer path of the apparatus is reduced and, since the harmful effect of the vacuum on the cows is eliminated, one to p can work with two or three pairs of milking machines, significantly increasing labor productivity. Milk volume sensors, with milking machines, are connected to milk and vacuum wires or autonomous connecting elements 43, however, it may be an option when both milk volume sensors are located on the same connecting element.
