Abstract

This invention relates to agriculture. The purpose of the invention is to improve the milking process and stimulate the milk reflex reflex. The milking machine contains two-chamber teat cups 1, a pulsator 2, a collector. A membrane-valve mechanism 4 is located in the manifold housing 3. The channel 8 of the membrane-valve mechanism current 4 communicates between each other the main 6 and additional 7 chambers of alternating pressure. The collector contains a milk receiving chamber 11 and a constant vacuum chamber 10 in which valves 12 and 13 are located. When vacuum is applied to chamber 6, and through channel 8 in the additional chamber 7 of the collector valve 12 opens and valve 13 closes. There is a tact suck. When overpressure is applied to chamber 6, a compression stroke occurs. Through the channel 8, the excess pressure enters the collector chamber 7, the valve 12 closes. The valve 13 opens. There is a tact of rest. 1 hp f-ly. 3 il. i O)

The invention relates to agriculture, in particular to milking machines.

The purpose of the invention is to improve the milking process and stimulate the milk reflex reflex.

FIG. 1 shows the scheme of the milking machine; in fig. 2 - teat cup; in fig. 3 shows section A-A in FIG. 2

A milking machine consists of two-chamber milking cups 1, a pulsator 2, a collector, milk tubes, vacuum hoses and nozzles for interconnecting these components and parts. The collector consists of a housing 3 in which a diaphragm-valve mechanism 4 is located, periodically disconnecting the podoskovye chambers 5 of teat cups 1 from a vacuum source (not shown), the main 6 and an additional 7 chambers of alternating pressure. The channel 8 of the stem of the membrane-valve mechanism 4 interconnects chambers 6 and 7 and the chamber 9 of the alternating pressure of the pulsator 2. The manifold also contains a chamber 10 of constant vacuum and a milk receiving chamber 11, in which lower 12 and the upper 13 valves of the membrane-valve mechanism 4. For connecting the teat cups with milk dispensing chambers and removing the milk, the collector body 3 has nozzles 14 and 15, for supplying variable pressure from the pulsator 2 nozzles 16, and nozzle 17 for supplying variable pressure from the collector to interstate nym chambers 18 of the teat cups.

In the body of the teat cup 1, a nipple tube 19 is placed, consisting of a suction part, an upper elastic cylindrical part 20, and a lower cylindrical nipple part 21 facing the milk nozzle / which is rigid due to the non-attachable cylindrical insert 22 or due to thickening of the nipple wall tube.

 Milking machine works as follows.

When the vacuum from the chamber 9 of the pulsator 2 enters the chamber 6, and through the channel 8 into the additional chamber 7, the membrane-valve mechanism 4 is lowered and the lower valve 12 opens, the upper valve 13

3, it closes, and in chambers 10 and 11 of the collector, 5 and 18 teat cups 1 creates a vacuum. There is a tact suck.

When the pulsator 2 from chamber 9 enters the overpressure chamber 6 and the interstitial chamber 1B of the teat cup 1 with a preserved vacuum under the nipple, a compression stroke takes place, during which the outflow of milk from the nipple continues, since the tip of the nipple in this case is not pressed by the opposite walls of the lower part 21 nipple tube. Due to excessive pressure, the nipple body is massaged by the upper elastic part 20 of the nipple tube, stimulating the milk flow reflex and promoting milk removal.

Through the channel 8, the overpressure enters the collector chamber 7, the membrane-valve mechanism 4 rises, the lower valve 12 closes, the upper 13 opens. The chambers 11 and 7 are connected to each other and to the spout chamber 5, in which an overpressure is established, and in the chamber 18 it is maintained. There is a tact of rest.
