RU69701U1 - COLLECTOR OF THE MILKING MACHINE - Google Patents

Abstract

The utility model relates to agriculture, in particular to collectors of milking machines. The objective of the utility model is to simplify the design of the collector and increase its operational reliability and reduce the risk of mastitis in animals. The problem is solved in that in the known collector containing a constant vacuum chamber and a milk collection chamber in which the hollow rod is located, the milk collection chamber is equipped with a float connected to the hollow rod. A shoulder is made in the upper part of the hollow rod, dividing the upper part of the milk collection chamber from the constant vacuum chamber.

Description

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

A known collector of a milking machine comprising a housing provided with a lid and nozzles, in which there is a valve connected to the membrane, there are also constant and variable vacuum chambers and an atmospheric pressure chamber in the housing.

The disadvantage of this collector is the complexity of the design and the reliability of the work due to the fragility of the membrane.

A pulse collector of a milking machine is known, comprising a housing equipped with a lid and nozzles, in which a membrane is mounted connected to a spring-loaded hollow rod, constant and variable vacuum chambers are also located in the housing, the variable vacuum chamber being also a milk collecting chamber.

The disadvantage of such a pulse collector is the design complexity and unreliability in operation due to the fragility of the membrane.

The disadvantage is that after the end of milk transfer, the duration of the sucking stroke is not reduced.

The objective of the utility model is to simplify the design of the collector, increase its operational reliability and reduce the risk of animal mastitis.

The problem is solved, in that in the known collector comprising a constant vacuum chamber and a milk collection chamber in which the hollow rod is located, the milk collection chamber is provided

a float connected to a hollow stem. A shoulder is made in the upper part of the hollow rod, dividing the upper part of the milk collection chamber from the constant vacuum chamber.

The essence of the utility model is illustrated in the drawing, which shows a diagram of the collector.

The collector comprises a housing 1 with milk pipes 2 and with a power pipe 3, a constant vacuum chamber 4, a milk collection chamber 5 (which is also a variable vacuum chamber) and a cover 6.

A float 7 is installed in the milk collection chamber 5, the upper end of which is located in the recess 9 of the lid 6. On the hollow rod 8 there is a shoulder 10 separating the milk collection chamber 5 from the constant vacuum chamber 4, which is formed by the power pipe 3, the hollow rod 8 and a recess 9 in the cover 6.

To avoid jamming when raising or lowering the hollow rod 8, a guide 11 is made in the lower part of the hollow rod.

For communication with the atmosphere, the milk collection chamber 5 is provided with openings 12.

The collector works as follows.

When the collector is put into operation through a loosely closed (with a gap) opening of the power pipe 3, the vacuum enters the milk collection chamber 5 and into the suction cups of the milking cups (not shown). Under the action of vacuum, milk enters the milk reception chamber 5 and with an increase in milk yield, the latter is filled with milk, the float 7 with the hollow rod 8 floats and milking occurs under a working vacuum. The float 7 with the hollow rod 8 easily floats up, because the pressure difference tending to lower them is practically not affected by the float 7 and the hollow rod 8. In addition, at the beginning of the rise, on the annular surface of the shoulder 10, separating the milk collection chamber 5 from the working

vacuum in the chamber 4 of a constant vacuum, a pressure differential is applied which tends to raise the bead 10 with the hollow rod 8.

With a decrease in milk yield, the float 7 with the rod 8 is lowered, blocking the opening of the power pipe 3 loosely and, together with the incoming air, a gentle vacuum is established through the hole 12 in the milk collection chamber 5. At the same time, a pressure differential begins to act on the annular surface of the shoulder 10 and, with its increase, the rod 8 with the float 7 rises, the working vacuum again begins to flow into the milk collection chamber 5, which corresponds to the suction stroke.

With the arrival of the working vacuum in the milk collection chamber 5, the pressure drop acting on the bead 10 disappears, the float 7 with the hollow rod 8 is lowered and a gentle vacuum is again formed in the milk collection chamber 5, which corresponds to a resting stroke. What does the rise of the float 7 with the hollow rod 8, in the absence of milk in the milk collection chamber 5 is possible only after the formation in the last gentle vacuum, i.e. after a beat of rest. Moreover, in the absence of milk in the milk collection chamber 5, the float 7 lowers quickly, i.e. faster is the beat of rest, and the time of the harmful effects of the working vacuum on the nipples of the udder of the animal is reduced.

The proposed technical solution simplifies the design of the collector, increases operational reliability, reduces the risk of animal mastitis.
