Description

In known milking machines, milking of cows is carried out in buckets, so cleaning, cooling and pumping milk are accompanied by its repeated transfusion, which increases the complexity of the process and reduces the quality of milk.

In the proposed installation, these disadvantages are eliminated, since milking is carried out in it in the milk line. The installation is made in the form of a milk line consisting of a milk pipe under vacuum, a round water countercurrent irrigation cooler, a diaphragm milk pump and a device for dispensing milk in a tank. Among the advantages of the proposed installation should also include the possibility of rational use of production space in the barn.

FIG. 1 shows the installation, side view; in fig. 2 — a device for monitoring the lactation process, taking into account milk yields at control milkings, washing and storing milking machines; in fig. 3- cooler-aerator in vertical section; in fig. 4 — a device for dispensing milk into floss.

The installation consists of the following main units and assemblies: frame I, which is a supporting metal structure for accommodating milking machines and equipment, milking and washing lines 2, hoppers 3 for concentrated feed, power unit 4 -c cooler-aerator, devices 5 for spilling milk by flush, water pump 6, mobile power station 7 and front 8.

Milking machines 9 are designed for fixing cows in them during milking and securing a number of installation units and mechanisms. The compartments 10 accommodate milking machines, hoppers for concentrated feed and other equipment. Inside the frame installation ukre№ 125446-2 -

milk and washing lines 2 and arcs for fixing cows. Machines 10 for cows are closed by doors on which feeders are suspended. The top tube, being a frame element, is also the vacuum line of the installation. Milking machines 2 (milks, pulsators, collectors, hoses), a milk line, and a device through which to dry milk, monitor milk yield, control milking, wash and store milking machines, enter milking and washing lines 2. This device consists of a four-position crane 12 idol bucket 13 with two interchangeable roofs. The lid 14 of the bucket has a float with a rod-pointer 15, a tube 16 in which the rod moves, a graduation scale 17 and a nipple 18. In the lower part of the bucket there is a second nipple 19. The crane consists of a body (not shown in the drawing), a stopper 20 and a glass vessel 21 (viewing device) fixed to the bottom of the hull. In the housing there is a tube 22, the lower edge of which does not reach the bottom of the viewing device by 1-2 mm. The crane body has four external nozzles (not shown), which are respectively connected to the milk line 23, the lower collector chamber 24 through the viewing device 21 and the upper and lower nozzles 18 and 19 of the bucket. The bunker 5 is intended for storing a reserve of concentrates and feeding portions of food ъ of the feeder during milking. The power unit 4 is a metal cabinet equipped with a pair of pneumatic wheels 25. The cabinet contains: a vacuum pumping unit 25 (a vacuum pump, a vacuum cylinder with a vacuum regulator and an electric motor), a milky diaphragm pump 27, a boiler 28 and vacuum cooler-aerator 29 of milk. The irrigation counterflow water cooler-aerator consists of an inner corrugated (with corrugations running along a helical line) cylinder 30 inserted into the outer cylinder 31. The cooler is closed from above with a lid 32 with two nozzles, through one of which air is sucked from the cooler, through the other milk is sucked. At the bottom, the cooler is closed by a transparent tray 33 with a pipe 34, through which milk is sucked. A distribution trough 35 with openings is inserted inside the cylinder. Two nozzles are welded into the outer cylinder. Coolant water is supplied through the nozzle 36, which, under the action of vacuum, flowing upwards between the walls of the cylinders 30 and 31, cools the milk flowing along the inner walls of the cylinder 30. Through pipe 37, water is discharged from the cooler.

A feature of this cooler is the location of the working surface inside the cylinder, whereby the cooling of the milk takes place in a volume under vacuum, and the milk does not come into contact with air. Simultaneously with the cooling, the milk is subjected to intensive aeration (aeration), in which all extraneous odors are removed from it.

The cooled milk is pumped through a diaphragm pump into the container. The installation provides a device for dispensing milk in flush with automatic cessation of milk supply to filled flies. The device consists of a tray 38 with a lid 39 and a pipe 40 for connection to a milk pump. In the bottom of the tray there are nozzles 41 having a supporting flange 42 in the lower part. A cross-shaped rod 43 is inserted into the nozzle, at the end of which a float 44 with a rubber gasket 45 lowered in a fl is pressed. When flooded, the float rises to the bottom the plane of the support flange, and the flow of milk in the flu is stopped.

Subject invention

Universal milking installation, characterized in that, in order to reduce labor costs for milking and primary processing of milk, improving the quality of milk, and rational use of production space in the barn, it is designed as a production milk line consisting of milking and washing lines , a round water countercurrent irrigation cooler-aerator, a diaphragm milk pump and a device for dispensing milk in a tank.
