Description

The invention relates to agriculture, in particular to milking apparatuses.

The purpose of the invention is to improve the milking process by programmatically changing the operating parameters.

FIG. 1 shows the proposed device, a general view; in fig. 2 - graphs of the vacuum pressure change in the control chamber of the additional pulsator.

The device for milking cows contains a main pulsator 1 and an additional pulsator 2.

The main pulsator 1 consists of five chambers: constant vacuum 3, variable vacuum 4, constant atmospheric pressure 5 and control chambers 6 and 7. The pulsator 1 also contains a large 8 and small 9 membranes and a valve mechanism 10. Chambers 6 and 4 are connected by a throttle channel 11. The nozzle 12 is connected with a hose to the milking unit collector, and the nozzle 13 is connected to a vacuum line.

Pulsator 2 consists of four chambers: constant vacuum 14, variable vacuum 15, constant atmospheric pressure 16 and control chamber 17. Pulsator

2 also a diaphragm, a valve mechanism 18, a throttle channel 19 connecting the chambers 15 and 17, the cross section of which is adjusted by a screw 20, and a channel 21 with a cork valve 22 connecting the chambers 14 and 17. A nozzle 23 connects the chamber 14 to a vacuum line, and channel 24 - chambers 17 and 7 of pulsators.

The device works as follows.

Before turning on the milking machine, there is air in all the chambers of the pulsators, valves are in the lower position, chamber

3 is connected to the chamber 4, the chamber 15 is connected to the chamber 16, the valve 22 is open and the chamber 17 is connected to the chamber 14. After connecting the nozzles 13 and 23 to the vacuum line, the air is almost simultaneously pumped out of the chambers 3, 4, 14 and 17.

The air pressure on the membrane 8 from chamber 6 toward chamber 3 prevents air pressure from chamber 5 toward chamber A and from chamber 6 toward the chamber 7, while the valve rises up, because the area of the membrane 8 exceeds the total area of the small membrane 9 and the lower valve. The valve mechanism 18 is held in the lower position by air pressure from the chamber 15 side to the chamber 14. After the pulsator is put into operation, the valve 22 is closed, the air from the chamber 17 stops pumping out. glasses, providing tact suck. After the air is pumped out through the channel 11 from the chamber 6 by the pressure of the air from the chamber 5 side to the chamber 4, the valve of the valve mechanism 10 will switch to the upper position and air will enter the chamber 4 and the interstitial cavities of the cups, thereby ensuring a massage stroke. The air will act on a large area of the valve from the side of the chamber 4 to the side of the chamber 3 and hold it in the up position during the massage stroke.

At the beginning of work, chambers 17 and 7 were underpressure and, therefore, the residual air pressure from chamber 6, membrane 9, tended to rise. This action reduces the sucking stroke, i.e., the suction capacity of the milking unit is reduced. This meets the physiological requirements for machine milking.

When the valve 22 is closed, the chamber 17 slowly flows through the throttle channel 19 from the chamber 15. The duration of the entry of air into the chamber 17 is due to its large volume. When the pressure in chambers 17 and 7 is increased, the air pressure on the membrane 9 will change its direction and will act downward, increasing the position of the valve in the lower position, thereby increasing the suction stroke and thereby increasing the suction capacity of the milking machine. The suction capacity of the milking machine increases gradually as the distance increases in chambers 17 and 7. At this time, the milk output of the cow increases. Upon reaching

Under a vacuum of 17 chamber of a certain size, the valve of the pulsator 2 switches to the upper position and air is pumped out of the chambers 15 and 17 through the throttle channel 19. As the vacuum increases in chambers 17 and 7, the sucking stroke gradually begins to decrease. To account for the individual characteristics of animals quickly or slowly give the milk passing.

programmatically changing the parameters of the device can be slowed down or accelerated. This is achieved by changing the cross section of the channel 19 with the screw 20.

When an animal is milked by a milking machine, the parameters of which vary according to the program, the animal develops a conditioned reflex, which ensures the regularity of milk production. Even with inadequate preparation of the udder for milking stressful situations, the action of the milking machine causes a conditioned reflex of the milking stereotype and {iolokotdacha is carried out successfully.
