Description

The universal milking unit is designed for cleaning cows, heating water, washing the udder with warm water, massaging the udder, milking the cows, cooling the milk and transporting it under conditions of both stable and grazing cows.

FIG. .1 shows a longitudinal section of a milking unit; in fig. 2-three projections of the suspension of the refrigerator; in fig. 3-scheme of the milking unit in the barn.

The unit is mounted on a welded metal platform mounted on four wheels 1 and 2, the front ones of which are leading, driven through a gearbox from an electric motor 3 and controlled by a steering device with a steering wheel 4.

On the platform there is a cabin with machine and dairy compartments. A rotary vacuum pump 5 with a silencer 6 is installed in the engine room, equipped with an individual electric drive and receiver 7; vacuum cleaner type 5 for cleaning animals; machine installation 9 for the refrigeration compartment, consisting of two independent identical freon automatic machines, not connected by a refrigerant, but combined by a common refrigerant system, cooling and filter. Each machine has a compressor, a condenser, a shell-and-tube inhaler and a vane pump, which creates a circulation of coolant water. The refrigeration unit is automated due to the presence of two-position thermal switches, which turn off and on the electric motors of the compressor units when the temperature of the cooled milk changes within the specified limits. In addition, each machine can be turned off manually without disrupting the operation of another. The interior of the engine room is lined with felt or cork sound insulation.

In the dairy compartment, in its upper part, there is a hermetic chamber 10, communicating during milking with outside air through the filter 11. In the chamber 10 there are two rows of five milk receivers 12 equipped with receptacles in two rows (five in each row). Crane No. 95744-2 -

13 and bleed taps 14 with lead tubes for taking milk. Milk receivers are either fissioned or suspended on dial scales for individual metering (by volume or weight) of milk from each cow. Supervision over the work of the milk receivers is conducted through the side windows of the cabin.

Each row of milk receivers has a plate cooler 15, having a distribution trough 16, a collection trough 17 and flexible hoses: supply water 18, output water 19 and drain for milk 20.

For automatic horizontal and vertical self-installation of refrigerators / 5, regardless of the inclination of the milking unit on uneven floors or soil, each refrigerator is mounted on two: hinged hinges. In the supports 2} of the pillars 22, the longitudinal fingers 23 are rigidly connected to the frame 24. In the latter, the transverse rollers 25 are rigidly inserted, rigidly connected to the refrigerator 15. The hinge at points 23 allows the cold fitting to be installed in a vertical position and the hinge at points 25 in a horizontal position, aided by its below-balanced balance weights 26.

A retractable container 27 with a capacity of 500-600 liters, having double walls, between which coolant circulates to maintain the low temperature of the already cooled milk, is located in the lower part of the dairy compartment. The container 27 is provided with a receiving filter 28, an exhaust valve and rollers 29, facilitating the extension of the container from the chamber along the guides.

On both sides of the dairy compartment there are tanks, which represent a bath for washing the bottom equipment with heated water supplied here from the tank 30 in front of the machine compartment, which is electrically heated. Heat water also serves to wash out the udder of cows, and hot water by pumping it through a refrigerator can be used to pasteurize milk.

On the roof of the cabin roof there is a tubular frame 31 for lighting rubber hoses; oiling machines 32, cleaning devices 33, washing 34 and massage 55.

The milking unit is supplied with electric power, which drives the electric motors of individual drive of its mechanisms and running gear, from the internal combustion engine with the electric generator (detachable power station 37) installed on the platform of the unit (if the latter operates under the conditions of grazing of cows) or outdoors (if the unit is working in the barn). In the latter case, the current is supplied by a flexible cable with a drum or plug device. In the case of a centralized power supply, the latter can be transmitted through bare conductors located under the ceiling of the room through the current collector 36 or by means of a cable suspended on moving rings to the cable tensioned along the passage.

The unit is controlled by the driver-driver from the outside platform, where the corresponding handles and the board with the instruments are brought. In addition, the unit serves two more to one rki, one assistant and one milk accountant. The unit advances along the passage between the barn stalls, stopping as necessary, against certain stalls (Fig. 3). Up to 5S with an assistant 55, the cow's udder was washed and massaged, the milking cups were put on and removed, and ten cows in stalls labeled Nos. 1–5 were milking at the same time as the milk receivers and switching on the taps for the descent of milk through the refrigerator into the container. At the end of the milking, the unit returns to its original position in a special room at the end of the barn, where the container of milk rolls out of the cabin and can be sent to its intended purpose, and the equipment of the unit is cleaned and washed.
