Description

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

A known collector of a milking machine, including a milk collection chamber with an outlet pipe, milk traps with main and drain holes and with floats connected by rods to valves located in milk reception chambers in which the guides for the valves are made. [one]

However, such a collector has a complex structure.

Another disadvantage is the unreliability of the collector due to clogging of the calibrated drain hole.

Known pulse collector of a milking machine containing a pulsator, communicated by a channel with a milk collection chamber, a body equipped with nozzles with milk reception chambers and with hollow conical valves overlapping the bypass holes, and drain holes are made in the bottoms of the milk reception chambers. [2]

The disadvantage of such a pulse collector is the unreliability of operation, since, when the drain holes are clogged, the vacuum may not enter the milk reception chambers and the conical hollow valves will not be able to float above the bypass holes, due to which milking may not start.

In addition, the differential pressure is applied to the conical hollow valves located in the bypass holes and, when the milk yield decreases, the valves quickly lower, blocking the holes, due to

which milking can stop before the end of milk transfer or productivity will decrease as the milk is sucked out only through the drain holes.

The disadvantage is that for the collector to work, it is necessary to have a channel communicating with the pulsator with the milk collection chamber, this complicates the design, makes it possible for milk to enter the interwall chambers of the teat cups, which increases the risk of milk contamination.

The objective of the utility model is to simplify the design of the collector, increasing the productivity and reliability of its operation.

The problem is solved in that in the known manifold containing a cover, a housing with a milk collection chamber and milk collection chambers, moreover, a valve is located in each milk collection chamber and an opening is made which communicates a milk collection chamber with a milk collection chamber, each valve is provided with a hollow stem, the upper end of each hollow stem being located in the lid. A shoulder is made in the upper part of each hollow rod.

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

The collector comprises a housing 2 with milk receiving chambers 3 equipped with milk pipes 1, a lid 4, which is mounted on the housing 2 with a washer 5 with a nut 6 and formed by a milk collecting chamber 8, which is also a constant vacuum chamber, formed by the lower surface of the housing 2 and the milk pipe 7.

In each milk receiving chamber 3 there is a hollow valve 9 connected to the hollow rod 10 and a hole 11 is made, which communicates the milk receiving chamber 3 with the milk collection chamber 8. Upper end

each hollow rod 10 is located in cylindrical recesses 12 made in the cover 4, while in the upper part of each hollow rod 10 is made a bead 13, and in the lower part of the guide 14.

For communication with the atmosphere, the milk reception chambers 3 are provided with openings 15.

The collector works as follows.

With the connection of the milk outlet 7 to a constant vacuum source (not shown), the vacuum is supplied to the milk reception chambers 3, and from them to the suction cups of the milking cups (not shown). Under the influence of vacuum, milk enters the milk reception chambers 3, the latter are filled with milk, hollow valves 9 with rods 10 float and the collector begins to work at a working vacuum. Hollow valves 9 with rods 10 easily pop up, because the diameter of the hole 11 is equal to the inner diameter of the hollow rod 10, because of which the pressure drop does not act on the latter. In addition, the bead 13 separating the milk reception chambers 3 from the working vacuum in the cylindrical recess 12 is affected by a pressure differential, which tends to raise the bead 13 together with the hollow rod 10 and with the hollow valve 9.

With a decrease in milk yield, the hollow valves 9 are lowered, blocking the hole 11 loosely (with a gap) and together with the incoming air, through the atmospheric hole 15, a gentle vacuum is formed in the milk reception chambers 3. After the formation of a gentle vacuum in the milk reception chambers 3, a pressure differential begins to act on the annular surface of the shoulder 13 and, as it increases, the rods 10 with valves 9 rise above the openings 11, the working vacuum again enters the milk reception chambers 3, which corresponds to a suction stroke. At the same time, with the arrival of the worker

vacuum into the milk reception chambers 3, the pressure drop disappears, the hollow valves 9 are lowered and a gentle vacuum is again formed in the milk reception chambers 3, which corresponds to a resting stroke. Moreover, the raising and lowering of the hollow valve 9 connected to the hollow rod 10 occurs individually regardless of the raising and lowering of the valves 9 in other milk receiving chambers 3.

In the absence of milk in the milk reception chamber 3, the hollow valve 9 lowers quickly, i.e. the beat of rest is faster, and the time of the harmful effects of the working vacuum is reduced, and therefore the risk of animal mastitis is reduced.

The proposed technical solution simplifies the design, increases operational reliability and increases the performance of the collector.
