Abstract

FIELD: agricultural engineering.

SUBSTANCE: apparatus has heat-insulated vessel, branch pipe with valve for connecting vessel to water supply system of milking unit and branch pipe with valve for supplying washing liquid to valve-type sprayer. Hollow corrugated vacuumizer is mounted within heat-insulated vessel. Space between vacuumizer walls is connected through union and hose to vacuum pipeline. Vessel is connected via hose to water supply system of milking unit and corrugated vacuumizer is filled with washing liquid to required level controllable by means of viewing window, followed by closing of valve and disconnecting of hose. Before milking procedure, valve is connected to vacuum pipeline, valve is opened and washing liquid is supplied to valve-type sprayer. By depressing sprayer valve, operator directs washing liquid onto animal's udder with force regulated by valve. Upon completion of udder rinsing procedure, operator releases sprayer valve to interrupt supplying of washing liquid.

EFFECT: simplified construction and increased efficiency of udder treatment.

Description

The invention relates to the field of agriculture, in particular to devices for processing the udder before milking. It can be used on livestock farms and farms.

A device for washing the udder, used on a mobile milking unit. It contains a container for washing liquid, mounted on a mobile trolley, connected via hoses to the discharge pipe of the vacuum pump and sprayer / 1 /.

The disadvantage of this device is that in the cold season there is a quick cooling of the washing liquid, and there is no possibility of regulating its pressure during spraying. Vibration and noise caused by the operation of a vacuum pump mounted on a cart of the milking unit have a negative effect on animals, which leads to a decrease in milk yield.

Also known is a device for washing the udder of animals, used on mobile milking machines and adopted as a prototype. It contains a thermally insulated container with nozzles for connecting to the water supply system of the milking unit, for supplying washing liquid through the hose to the valve sprayers and to the vacuum pipe of the milking unit. The capacity is rigidly fixed on the frame of a mobile milking unit / 2 /.

This design does not allow for a good washing of the udder, since water is supplied to the sprayers under its own weight due to the difference in its levels in the tank and sprayers. At the same time, the rate of water outflow from the nebulizers is insufficient to completely remove impurities from the surface of the udder of the animal.

The objective of the proposed technical solution is to increase the processing efficiency of the udder.

The problem is solved by the fact that inside the insulated tank there is a hollow evacuated corrugated chamber with a lid filled with washing liquid. The interstitial space of the corrugated chamber is connected to the vacuum line of the milking unit by means of a fitting and a hose, and the tank itself is connected to the water supply system of the milking unit and the valve spray by means of nozzles with valves and hoses. To control the level of washing liquid in a thermally insulated container there is an inspection window.

The proposed device for pre-milking the udder is illustrated in the drawing.

A device for pre-milking the udder consists of a thermally insulated container 1, pipe 2 with a valve 3 for connecting to the water supply system of the milking unit and pipe 4 with a valve 5 for supplying washing liquid through a hose 6 to the valve spray 7. Inside the thermally insulated container 1 there is a corrugated chamber 8, the inter-wall space 9 of which, using the nozzle 10 and the hose 11, is connected to the vacuum pipe 12 of the milking unit. The insulated container 1 is closed by a perforated lid 13, which allows to reduce heat loss and prevents the ingress of contaminants. To monitor the level of washing liquid in the insulated container 1, there is a viewing window 14. Using a hose 15, the insulated container 1 is connected to the water supply system of the milking unit.

The proposed device for pre-milking the udder works as follows. Using a hose 15, the insulated container 1 is connected to the water supply system of the milking unit and, by opening the valve 3, the corrugated chamber 8 is filled with washing liquid at a temperature of 45-50 ° C to the required level. After filling the corrugated chamber 8 with the washing liquid, the valve 3 is closed and the hose 15 is disconnected. Before milking begins, the operator connects the insulated container 1 to the vacuum line 12 of the milking unit, and the interwall space of the corrugated chamber 8 is evacuated. The operator opens the valve 5, the washing fluid due to the difference between atmospheric and vacuum pressure in the inter-wall space of the corrugated chamber 8 and its own weight is fed to the valve sprayer 7 through the hose 6. Pressing the sprayer valve 7, the operator supplies the cleaning fluid to the udder of the animal with an effort controlled by the valve 5. The udder is washed. Having washed the udder of the animal, the operator releases the valve of the sprayer 7, and the flow of washing liquid is stopped.
