Description

one

Three-stroke milking machines are known, containing teat cups, a pulsator, and a manifold connected to the milk conduit with vacuum and atmospheric valves, alternately connecting its milk chamber to a vacuum source and to the atmosphere. However, significant fluctuations in the vacuum under the nipple in tact have negative effects on the quality of release and the health of animals. In addition, transporting milk and air through a single hose causes air to drop in vacuum, while air passing through the hose degrades the quality of the milk.

In the proposed milking machine, in order to stabilize the vacuum mode during milking into the milk line and eliminate air intake, the milk chamber in the upper part is connected to the vacuum wire, the end of which serves as the seat of the vacuum valve, and float and check valves are installed at the point of its connection to the milk line.

The drawing shows schematically the proposed three-cycle milking machine.

The milking machine contains a pulsator 1 and a collector 2 with attached to it teat cups 3. The collector has a vacuum valve 4, the saddle of which serves as the end of the vacuum wire 5, and an atmospheric valve 6 telling the milk chamber 7 of the collector

the atmosphere. The valves 4 and 6 are located on the same rod and are controlled by a membrane 8 from a non-intermittent vacuum chamber 9 connected to a pulsator. The milk chamber of the collector is equipped with a float valve 10, which closes the entrance to the milk line 11, and is connected to the milk line through a check valve 12. The milk chamber contains the maximum portion of milk that is discharged in one

tact without falling into the vacuum-wire. The milk line 11 and the vacuum wire 5 are connected to a common vacuum source.

When the apparatus is in operation, the variable vacuum from the pulsator spreads into chamber 9.

When vacuum is in chamber 9, atmospheric valve 6 is closed and vacuum valve 4 is open. A vacuum (suck stroke) is established in the milk chamber 7 of the collector and in the milking areas of the teat cups. The milk extracted from the nipples enters the chamber 7 and collects in it, raising the float valve 10. At the same time, the check valve 12 is closed, preventing the milk from returning from the milk line Eve to the milk chamber.

When atmospheric pressure is established in chamber 9, the vacuum valve closes and the atmospheric valve opens. Atmospheric

pressure (rest tact). At this time, the milk from the milk chamber under the action of the pressure difference is displaced into the milk line 11, opening the check valve 12. After passing the milk, the float valve 10 closes the entrance to the milk line 11, preventing air from entering into it and the vacuum spreading into the milk chamber. Then the cycle is repeated.

Subject invention

A three-stroke milking machine containing milking cups, a pulsator and a manifold connected to the milk conduit with vacuum and atmospheric valves, alternately connecting its milk chamber with a vacuum source and with the atmosphere, characterized in that, in order to stabilize the vacuum mode during milking in the milk conduit and eliminate the inlet air in it, the milk chamber in the upper part is connected to the vacuum-wire, the end of which serves as the seat of the vacuum valve, and in the MLV there are float and reverse valves.
