Description

The utility model relates to techniques for servicing animals, namely, equipment for milking them in stalls, mainly with tethered keeping.

Known milking unit containing a milking milk line, passing into the transport, cranes for connecting milking machines, liquid flow switches, milk receiver air separator connected to a vacuum source, receiver, transport milk line and washing system 1.

This milking unit is intended for milking cows mainly in summer camps, and to stabilize the vacuum in the milk line, even with its relatively short length, an additional milk line is installed in it.

Closest to the proposed technical essence and application conditions is a milking unit containing milking pipelines installed along the rows of stalls, passing into transport ones, cranes for connecting milking machines, milk dispensers, liquid flow switches, dividers, dividing the milking pipelines into two branches, the milk receiver - an air separator connected to the transport milk line by means of dispensers, a vacuum source, a receiver and a flushing system 2.

The disadvantage of this milking unit is the instability of rarefaction in milk pipelines, not compensated by the presence of a receiver with an increased volume, which is due to the relatively high length of the milk pipelines and the remoteness of the milking machines from the vacuum source.

Milking machine

In the proposed milking installation, comprising milking pipelines installed along the rows of stalls, passing into transport, cranes for connecting milking machines, milk dispensers, liquid flow switches, dividers, dividing the milking pipelines into two branches, a milk collector-air separator connected to the transport milk piping by means of dispensers, a vacuum source, a receiver and a flushing system, on both sides of each separator are installed and connected to each branch of the milk pipelines of at least about one additional receiver.

In addition, at least one additional crane for attaching the milking machines can be installed on the milking milk pipelines on both sides of each separator, the additional receivers are made in the form of milk buckets with lids and are connected to the milking milk pipelines through additional taps via milk hoses.

Two nozzles can be installed on each lid of the additional receivers, one of which is connected by a hose through an additional crane to the milking line, and the second is equipped with an air valve. A pipe connected by a hose to an additional valve is flush mounted with the B1hug surface of the cap, the pipe with an air valve is mounted protruding above the inner surface of the cap, and the inner surface of the cap is made spherical.

Such a constructive solution allows not only to increase the supply of vacuum in the system, but mainly to bring receivers closer to milking machines (consumers of vacuum) and thereby significantly reduce pressure pulsations (vacuum) in the milk pipeline. Installing additional taps for attaching milking machines on both sides of the dividers allows you to connect additional receivers

directly by milking and turn them off after milking, which makes it possible to rinse the milking unit in the usual technological mode, provided for by the manufacturer's instructions. The implementation of additional receivers in the form of milking buckets with lids and connecting to the milking milk pipelines through additional taps using milk hoses facilitates the washing of additional receivers. They are washed separately in the dairy along with milking machines. Installing on each lid of the additional receivers two nozzles, one of which is connected by a hose through an additional valve with a milking line, and the second is equipped with an air valve, the nozzles connected by hoses with additional valves are flush with the inner surface of the covers, and the nozzles with air valves mounted protruding; them above the inner surface of the lids, and the implementation of the inner surfaces of the lids of a spherical shape, provides the possibility of transporting milk that has been added After receiving milking into the milking line, install the receiver by installing the receiver with the lid down and opening the air valve.

In FIG. 1 shows a diagram of a milking unit in milking mode. In FIG. 2 - general; view of the additional receiver. In FIG. 3 shows a diagram of a milking unit in the washing mode.

The milking unit contains milking pipelines 1 installed along the rows of stalls and transferred to transport milk pipelines 4. Cranes 2 for connecting milking machines 3 are mixed; milks on the milking piping 1. When milking, transport milk pipelines 4 are connected via milk flow switches 5 and through milk dispensers 6 to milk separator-air separator 7, and the flushing system 19 is disconnected from the transport milk pipelines 4. Separators 8, dividing milk pipelines during milking on two branches, are installed on milking

milk pipelines 1. The milk collector-air separator 7 is connected to a vacuum source 9 through a safety chamber. The vacuum source 9, for example, a liquid ring vacuum pump, is equipped with a receiver 10 and a pressure regulator. On milk pipelines 1 on both sides of the dividers 8 are installed additional cranes 11 for connecting milking machines to them. Additional receivers 12 are made in the form of milking buckets with lids 13. Two nozzles 14 and 15 are installed on the lids 13, A nozzle 14 is connected to an additional tap 11 by means of a milk hose 16 and installed flush with the inner surface of the lid 13. The inner surface of the lid 13 is made spherical. The pipe 15 is equipped with an air valve on the outside of the lid, and a protruding mount is mounted on the inside of the lid; it is above its surface. The air valve is made, for example, in the form of an elastic cup with a hole on the side surface. An opening is made on the side surface of the pipe 15. Vacuum lines 17 and 18 are connected to the receiver 10. Vacuum lines 18 may be absent in the case of milking machines, you can connect them only to the milk line and without lifting branches of the milk lines or devices for their automatic lowering with help; and vacuum. In this case, the position 18 should be understood as the supporting structure of the milk pipelines.

Milking installation works as follows.

During milking, the fluid flow switches 5 are set to a position that disconnects the flushing system 19 from the transport milk pipelines 4. The transport pipelines 4 are connected via flow switches 5 to the dispensers 6. The dividers 8 are installed in a position that divides the milk pipelines 1 into two branches. Through additional taps 11, additional receivers 12 are connected to the milking milk pipelines 1. From the vacuum source 9, the vacuum enters sequentially into the receiver 10, milk collector-air separator 7,

transport 4 n milking 1 milk pipelines, then through additional taps I, milk hoses 16, nozzles 14 to additional receivers 12. Milking machines 3 are connected to the cranes 2. Milk is fed from milking machines 3, through cranes 2 to milking milk pipelines 1, and then to transport milk pipelines 4. From transport milk pipelines 4, milk is supplied through milk flow switches 5 to milk dispensers 6. From dispensers 6, milk enters milk collector-air separator 7, and from it is fed to the milk processor for primary processing (filter iju, cooling, etc.). With increased air flow in the section of the milking milk pipeline (connecting milking machines), rarefaction arrives at this section from the receivers 10 and 12. During the cork mode of movement of milk in the transport and (or) milking pipelines, the resulting milk plug disconnects the milking pipeline from the vacuum source, at this time additional receivers 12 provide pressure stabilization in them. After milking, the additional receivers are set down with the lid and open the air valve on the nozzle 15. The air penetrating through the holes in the elastic cup and the nozzle increases the pressure in the additional receiver 12 and displaces milk from it, into the milk milking duct 1 and then into the milk collector air separator 7.

After milking is completed, before flushing, the flow switch 5 is placed in a position that connects the transport pipelines 4 to the flushing system 19 and to the milk dispensers, and additional receivers 12 are disconnected from the milking milk line 1 by means of additional taps 11. The dividers 8 are moved to the position that combines both branches of the milk pipelines. Then the washing of the milking unit is carried out in the sequence provided by the design and in the mode recommended by the manufacturer's instructions.

prototype, will reduce the pressure pulsation (vacuum) in the milk pipelines, which will improve the operation of milking machines and reduce the incidence of cows with mastitis.
