Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to milking machines.

The purpose of the invention is to improve the mode of milking by adjusting the amount of vacuum during operation.

The drawing shows a diagram of the milking machine.

The milking machine contains two-chamber milking cups 1, a collector 2, having four receiving chambers 3, a milk collecting chamber 4 with a valve 5 and a milk branch pipe 6. Each chamber 3 contains molokolushki 7 with a float 8 installed movably in a glass 9, defined the float 8. When the glass 9 overflows, the milk into the milk-collecting chamber 4 enters the annular neck 10. At the bottom, the float 8 is equipped with a needle 11, which at the bottom position of the float 8 forms a calibrated slot in the hole 12.

In the upper part of the molokolushka 7, which is connected to the podskoskovy chamber 13 of the teat cup 1, there is a partition 14, as well as additional chambers 16 and chambers 17 packs separated by a membrane 15

The milk pipe with a pipe 6 connects the collector 2 to the milking bucket or milk pipe (not shown) and opens the valve 5. At the same time, the vacuum through pipe 6 is distributed to the milk collection chamber 4 and further to the receiving chambers 3, where 10, penetrates into the molokolushku 7 and further into the podoskovo space of the teat cup 1. The vacuum, having entered the additional chamber 16, will bend the membrane 15 until it touches the partition 14, closing the slit 25, as well as through the opening 23 formed by the nest 18 and located in the bottom position the valve 21 will penetrate into the cylindrical rack 20 and further through the perforations into the control chamber 17, where a predetermined vacuum stimulating effect on the nipples (low vacuum) will be established by the flow of air through the calibrated orifice 24. Under the influence of the pressure difference 2Q of the research institutes in the additional 16 and 17 control chambers, the membrane 15 rises, forming a slit 25 and opening the access of vacuum to the variable vacuum chamber 16 and further along the inlet milk branch pipe 26 to the milking pouch 13 of the milking stack 15

Before putting the teat cup 1 on the teat of the udder in the podskoshka chamber 13 and the inlet milk nozzle 26, it will be almost atmospheric pressure slot 18, in its lower position, it is flat. The same atmospheric pressure passes through the calibrated orifice 23. The control chamber 17 is in communication with the atmosphere through the calibrated orifice 24. The membrane 15 and the septum 14 form a slit 25. The milk supplying pipe 34 extends into the vacuum section 33 of the vacuum regulator 29. As a result, the applied vacuum in the stroke of the sos from the distributor 38 through the vacuum port 37 into the interstitial chamber 28 of the milking

The feed milk tube 26 contains a calibrated orifice 27. The milking cup contains a vacuum regulator 29, made in the form of a chamber divided by a membrane 30 into an atmospheric pressure section 31 with a calibrated orifice 32 and a vacuum section 33, through a nozzle 34 connected to the milking cup 13 of a teat Cup 1. The atmospheric pressure section 31 of the vacuum regulator 29 and the interwall wall 28 of the teat cup 1 are separated by a valve 35 connected by means of the rod 36 to the flexible membrane 30, the active areas of the valve 35 and the bend oh the membrane 30 is equal. To prevent the teat cups 1 from interfering with each other when the vacuum regime changes in the interwall chamber 28 of one of them, the vacuum tubes 37 connecting the interwall cells 28 to the distributor 38 of the collector 2 contain constrictions 39.

Milking machine works as follows.

access of air flow from atmospheric pressure chamber 31 to interstitial chamber 28.

40 The calibrated orifice 32 limits the amount of air entering the atmospheric pressure chamber 31, thereby providing, with the valve 35 in the wall chamber 28 fully open, a predetermined nipple stimulating vacuum.

To eliminate the interplay between the vacuum regimes of the inter-wall chambers 28 of the various teat cups 1, the vacuum nozzles 37 contain constrictions 39 that restrict the air flow through the vacuum nozzle 37.

After putting the teat cups I on, the teats of the udder of cows in the spraying chamber 13 establish a predetermined stimulating vacuum on the nipples, the size of which is determined by the amount of vacuum in the control chamber 17. At the same time, the membrane 15 is in equilibrium

The milk pipe with a pipe 6 connects the collector 2 to the milking bucket or milk pipe (not shown) and opens the valve 5. At the same time, the vacuum through pipe 6 is distributed to the milk collection chamber 4 and further to the receiving chambers 3, where 10, penetrates into the molokolushku 7 and further into the podoskovo space of the teat cup 1. The vacuum, having entered the additional chamber 16, will bend the membrane 15 until it touches the partition 14, closing the slit 25, as well as through the opening 23 formed by the nest 18 and located in the bottom position the valve 21 will penetrate into the cylindrical rack 20 and further through the perforations into the control chamber 17, where a predetermined vacuum stimulating effect on the nipples (low vacuum) will be established by the flow of air through the calibrated orifice 24. Under the effect of the pressure difference QI, in an additional 16 and 17 control chambers, the membrane 15 is raised, forming a slit 25 and opening access of the vacuum to the variable vacuum chamber 16 and further along the inlet milk outlet 26 to the milking pouch 13 of the milking stack 5

Section 33 of vacuum regulator 29 in the interstitial chamber 28. Prior to putting the teat cup 1 on the teat of the udder in the spouting chamber 13 and the inlet milk tube 26, it will be almost atmospheric pressure. This is the atmospheric pressure on the palenne. The same atmospheric pressure over the nozzle 34 is distributed to the vacuum section 33 of the vacuum regulator 29. As a result, the applied vacuum in the stroke of the sos from the distributor 38 through the vacuum port 37 into the interstitial chamber 28 of the milking

resist the membrane 30, thereby opening

access of air flow from atmospheric pressure chamber 31 to interstitial chamber 28.

0 The calibrated orifice 32 limits the amount of air entering the atmospheric pressure chamber 31, thereby providing, with the valve 35 in the wall chamber 28 fully open, a predetermined nipple stimulating vacuum.

To eliminate the interplay between the vacuum regimes of the inter-wall chambers 28 of the various teat cups 1, the vacuum nozzles 37 contain constrictions 39 restricting the air flow through the vacuum nozzle 37.

After putting the teat cups I on, the teats of the udder of cows in the spraying chamber 13 are set to a predetermined stimulating vacuum on the nipples, the size of which is determined by the amount of vacuum in the control chamber 17. At the same time, the membrane 15 is in equilibrium and

A bath hole 27 in the inlet milk tube 26 and further into the additional chamber 16 provides for the transportation of milk. At the same time, the stimulating vacuum through the nozzle 34 enters the vacuum section 33 of the vacuum regulator 29. At the same time, the membrane 30, bending, by means of the stem 36, separates the atmospheric pressure chamber 31 and the interstitial chamber 28 of the teat cup 1 by means of the stem 36 transfer to the interstitial chamber 28 is equal to the vacuum in the vacuum line of the milking machine. Since a low vacuum is established in the vacuum section 33, equal to the vacuum in the pusher chamber 13 of the teat cup 1, the valve 35 will open, opening air from the atmospheric pressure chamber 31 to the interstitial chamber 28, and will remain open until the air in the interstitial chamber 28 and in the vacuum section 33 it is not equalized, i.e., the predetermined vacuum of the stimulating effect on the udder teat is not established in the interwall chamber 28.

Thus, milking is performed with low vacuum.

The milk comes from the spraying chamber 13 through the inlet milk tube 26 into the additional chamber 16 and then through the slit 25 into the glass 9 of the molokolushka 7. At the same time, if the amount of incoming milk does not exceed 50 g / min, it is through a calibrated slit formed in the hole 12 needle 11, goes to milk collection chamber 4 of collector 2. With an increase in milk intake of 50 g / min more, filling of glass 9 occurs and excess milk overflows through its edge

Variable vacuum vacuum pumps 16 are supplied through the inlet milk branch pipe 26 into the podskoskovaya chamber 13 of the teat cup 1, and through branch pipe 34 into the vacuum section 33 of the vacuum regulator 29. Since this prevents the possibility of opening the valve 35 and injecting a portion of air from the atmospheric pressure chamber 31 into the interstitial chamber 28 of the teat cup 1, during the suction stroke, the vacuum in the interstitial chamber 28 increases to nominal. This is how milking is performed with a nominal vacuum.

When the milk flow decreases below 50 g / min, the float 8 is lowered and the needle 11 partially overlaps the opening 12. At the same time, the float 8 with the valve 22 closes the valve 21. The vacuum in the control chamber 17 again becomes equal to the stimulating vacuum. At the same time, the membrane 15 will be propelled, reducing the gap 25 and thereby reducing the suction of air from the additional chamber 16. As a result, in the additional chamber 16 and further in the spouting chamber 13, as well as in the vacuum section 33 and, as a result, in the interwall. At least 28 of the teat cup 1, a low vacuum will be established. This is how re-stimulation of the milk flow and dody is performed with a low vacuum.

When the milking is completed, the valve 5 is closed and the teat cups 1 are removed from the udder of the animal.
