Description

The utility model relates to agriculture, in particular, to collectors of milking machines.

There is a known collector of a milking machine for quarter milking, including milk reception chambers with valves connected by rods with floats that are located in milk traps, while for communication with a milk reception chamber, bypass holes are made in the upper part of the milk traps, and drain holes are made in the lower part of the small milk traps. USSR copyright certificate No. 1818023 of 05/30/1993.

However, during the operation of such a collector, the risk of injury to the nipples of the udder of the animal is not excluded. milking occurs under constant vacuum in the suction cup without a rest beat, and the vacuum decreases only after the milk transfer stops with the milk trap emptying and the valve is lowered to the hole.

A known collector of a milking machine, including milk reception chambers having float valves and openings, a milk collection chamber and a variable vacuum chamber made in the housing of communicating channels. RF patent for utility model No. 97592 of 09/20/2010.

The disadvantage of this collector is that there is a risk of injury to the nipples of the udder, because milking occurs without a resting beat in the sucking-squeezing mode, and with a squeezing beat, part of the nipple continues to remain under vacuum.

Another disadvantage is that with a decrease in the intensity of milk flow, the collector begins to work with low productivity since the milk level in the milk reception chamber decreases, the float valve is attracted by the vacuum to the hole, due to which the evacuation of milk slows down.

The objective of the utility model is to reduce the risk of injury to the nipples of the udder of the animal and increase the productivity of the collector.

The problem is solved in that in the collector of the milking machine containing milk-holding chambers having float valves and openings, a housing in which there is a variable vacuum chamber made of communicating channels and a milk collection chamber, the milk collection chamber is equipped with a nozzle and a membrane, with the upper end of the nozzle connected to the housing and communicated with a variable vacuum chamber, and the membrane is mounted on the lower end of the pipe. A screw is installed in the housing that regulates the flow of air into the cavity of the nozzle. The essence of the utility model is illustrated in the drawing, which shows a diagram of the collector.

The collector comprises a milk chamber 1 equipped with milk pipes 1, a housing 2, in which an alternating vacuum chamber 4 is arranged, made of interconnected channels 5. Transparent glasses 6 are installed on the body 2, forming milk-receiving chambers 7 with cup-shaped recesses of the body 2, of which atmospheric openings 8 are made and float valves 9 are placed. The milk receiving chambers 7 are connected by openings 10 with a milk collecting chamber 11 formed by the lower part of the housing 2 and the milk outlet 12. In milk A nozzle 13 is installed on the chamber 11, the upper end of which is connected to the housing 2 and connected to the variable vacuum chamber 4, and a membrane 14 is mounted on the lower end of the nozzle 13, located above the inlet 15 of the milk outlet 12.

To regulate the flow of air into the cavity of the pipe 13 in the housing 2, a screw 16 is installed.

The collector works as follows.

The milk outlet 12 is connected to a constant vacuum source (not shown), and the variable vacuum chamber 4 is connected to a variable vacuum source (not shown).

With a suction stroke, the vacuum enters through the openings 10, not tightly closed by the float valves 9, into the milk reception chambers 7, and from the latter through the milk pipes 1 to the suction cups of the milking cups (not shown), at the same time from the chamber 4 of a variable vacuum, the vacuum through the air nozzles 3 enters the interstitial chambers of the teatcups (not shown), i.e. there comes a sucking beat.

During the compression stroke, air from a pulsator (not shown) enters the chamber 4 of an alternating vacuum, and from the latter into the interwall chambers of the teat cups. Due to the fact that the passage section of the nozzle 13 is closed by a screw 16 with a gap, the atmospheric pressure in the cavity of the nozzle 13 arrives late, and the membrane 14 does not prevent the vacuum from entering the milk reception chambers 7 and the suction cups of the milking cups i.e. there comes a compression stroke.

With the establishment of atmospheric pressure in the cavity of the nozzle 13, the membrane 14 bends and blocks the flow of vacuum through the hole 15 into the milk collection chamber 11 and into the milk reception chambers 7, while air continues to enter through the hole 8 into the milk reception chamber 7 and willow suction chambers of the milking cups - there is a beat .

With a low intensity of milk transfer (which occurs at the beginning and at the end of milking), during the sucking stroke, the float valve 9 is attracted to the hole 10 in the milk reception chamber 7, it easily pops up during the rest stroke, and is released to the hole 10 at the next suction stroke after the milk has expired .e. during milking practically does not interfere with the evacuation of milk from the milk collection chamber 7.

With an increase in the intensity of milk transfer, the float valve 9 floats above the hole 10 and milking occurs at a working vacuum in the mode of sucking - compression - rest.

With the end of the milk transfer of one of the nipples of the udder of the animal, the corresponding milk reception chamber 7 is emptied, the float valve 9 is lowered, blocking the opening 10 with a gap, the intake of vacuum into the milk reception chamber 7 is reduced, and together with the incoming air, a gentle vacuum is established in the suction chamber through the hole 8. . Moreover, the cessation of milk flow and the transition to a gentle vacuum of the remaining nipples of the udder occurs individually, regardless of milk flow in other nipples.

The duration of the compression and resting cycles can be adjusted with a screw 16, which changes the area of the passage section of the nozzle 13, through which the air coming from the pulsator during the compression cycle passes.

The proposed technical solution reduces the risk of injury to the nipples of the udder of the animal, increases the performance of the collector, provides the physiological process of milking.
