(54) MILKING MACHINE

one

This invention relates to agriculture.

A milking machine is known that includes teat cups interconnected by means of hoses, a pulsator and a manifold, which has atmospheric, vacuum and drain valves with an air-vacuum drive f,

However, in such a milking machine, the teat cups do not disconnect from the milk line during their milking.

A milking machine is also known, which includes teat cups interconnected by hoses, a pulsator, a vacuum stabilizer in the form of an elastic membrane connected to the milk line, and a collector having a nep “vteHHotx vacuum chamber and a milk chamber with a bottom 2 divided by a partition.

However, in such a milking machine, the milking cups do not disconnect from the milk line when they drop.

The purpose of the invention is the prevention of contamination of the breaker wire from hitting the teat cups from it when they fall down.

This is achieved by the fact that the blender has a check valve with a calibrated orifice located above the borehole filled in the partition wall, and the milk chamber has a baffle plate with the filled bore in it and is provided with a double acting valve, marked in the borehole and interacting with the bottom.

In addition, the alternating vacuum chamber is connected via a pulsator to a vacuum stabilizer;

The drawing schematically shows a milking machine.

The milking machine contains the teat cups 1, the collector with chambers 2. 3, 4, the elastic bottom 5, the return valve

0 pan 6 with a calibrated orifice 7, a two-way valve 8, a pulsator 9 and a vacuum stabilizer in the form of a 1O membrane, a nozzle 11 and a spring 12.

Vacuum hose 13 and milk lang 14 are used to connect the apparata to the milk line. The collector has

A partition 15 with an opening 16, above which there is a check valve 6, and 5 a partition 17 with an opening 18, equipped with a double-acting valve 8 located in the opening 18,

Chamber 2 (an unreasonable vacuum is created in it) through the pulsator 9 is connected to the stabilizer by a vacuum.

Milking machine works as follows.

When sucking vssuum in chambers 2 and 3 is the same, and in chamber 4 it is higher than in 15 chamber 3, the valve 8 is closed. The decrease in vacuum in chamber 3 with n TeHCiiBHoft milk yield is compensated. sucking air through the opening 7 into chamber 2, the pulsator 9 to the stabilizer va 20 kum into the milk conduit. Repeated pressure acting on valve b will be insignificant, since its weight is small.

With compressed air, the pulsator 9 supplies atmospheric pressure to chamber 2, the valve 6 25 closes, preventing eix from entering the chamber 3, but the vacuum i in the latter decreases due to air leaking through the opening 7,

With a reduced vacuum in Kaivtepe 3 30, valve 8 opens and the milk is evacuated from chamber 3. At the end of the compression stroke a vacuum flows into chamber 2, and the vacuum in chamber 3 is quenched. The valve 8 closes, starts 35

the cycle of sucking and the cycle of operation of the apparatus is repeated,

During the milking process, the return valve 6, under the action of the lifting force of the air flow, periodically, during the coca-40 cycle, separates the chamber 2 from the compressor and remains in this position until the compression stroke.

When the milking unit falls down with the teat cups in chamber 3, athetamine pressure is applied. Valve 8 is open, 3 mosquito -1 is also atmospheric daopenle. Then, as a result of the atmospheric drip, the elastic 5 deflection of the 1E1-SJ into kegmep 4 closes the valve 8s, the cohort remains in this position. The ycTpQuei.ujsi is in an emergency condition.

The proposed milking machine allows you to prevent s 1 gr knowledge of the milk line and, consequently, the spoilage of milk in the milking process.
