Abstract

This invention relates to agriculture. The purpose of the invention is to improve the milking process by increasing the accuracy of the simultaneous change in the vacuum level in the teat cup chambers. The vacuum regulator has a housing 4 with a vacuum chamber 5 and a throttle valve 6. The throttle valve 6 through the spring 7 communicates with an adjusting screw 8. The secondary chamber 10 has a vacuum gauge 12 and a nozzle 11 for connection with the milk container. The variable vacuum chamber 13 is provided with an overflow valve 14. The vacuum is supplied through the nozzle 17 into the vacuum chamber. By adjusting the degree of compression of the spring 7, the vacuum in the additional chamber 10 is adjusted. The vacuum from the additional chamber 10 enters the milk collection and podskoskovye chambers of the teat cups. When switching the valve 14, the vacuum from the additional chamber 10 enters the inter-wall chambers of the teat cups. 1 hp f-ly, 2 ill.

Description

bypass valve 14. Vacuum is supplied through 17 in. nozzle. vacuum chamber. Regulating the degree of compression of the spring 7, adjust the vacuum in the additional chamber 10. The vacuum from the additional chamber 10 flows into

milk collection and grinding chambers of teat cups. When the valve 14 is switched, the vacuum from the additional chamber 10 enters the inter-wall chambers of the teat cups, 1 ° C. f-ly. 2 Il.

The invention relates to agriculture, in particular to vacuum regulators.

The purpose of the invention is to improve the milking process by increasing the accuracy of the simultaneous change in the vacuum level in the teat cup chambers.

Figure 1 shows a diagram of the connection of a vacuum regulator to a milking machine; FIG. 2 shows a vacuum regulator, of a sectional view.

The milking machine includes two-dimensional milking cups 1, a pulsator 2 and a milk collector 3. The vacuum regulator has a housing 4 and a vacuum chamber 5 in it with a spring-loaded choke valve 6 for air bypass, spring-. Well 7, which interacts with the adjusting screw 8. The choke valve 6 opens and closes the vacuum access through the air channel 9 to the additional vacuum chamber 10 having a pipe 11 for connection with the urine collector 3,

A vacuum gauge 2 is connected to the additional vacuum chamber 10, attached to the housing 4 of the vacuum regulator and used to control and adjust the value of akum in the suction and inter wall chambers of the teat cups. The additional vacuum chamber 10 is connected by a channel 9 with a variable vacuum chamber 13, in which an overflow valve 14 is located. The branch pipe 15 communicates with the pulsator 2 of the milking machine, the branch pipe 16 with the inter wall chamber of the teat cups, and the branch pipe 17 - with a vacuum system.

The vacuum regulator works in the following manner.

The vacuum from the vacuum wire through the tee is fed to the pulsator 2 of the other device and to the nozzle 17, overcoming the resistance of the spring 7, the vacuum

The kum raises the throttle valve 6 and passes into the additional vacuum

chamber 10, causing a change in the indications of the vacuum gauge 12. The magnitude of the vacuum decreases in proportion to the spring 7 pressure.

Using the adjusting screw 8, you can set the desired amount of vacuum in the milk collector 3 and, accordingly, in the podskoskovo chamber milking cups. Initially, the pulsator 2 delivers atmospheric pressure to the nozzle 15, due to the difference in pressure; after rising above and below the bypass valve 15, it rises and closes the channel 9 into an additional vacuum one. chamber 10. Atmospheric pressure propagates through a variable vacuum hose into the interstitial space of the teat cups, causing compression of the nipple rubber. .

When the pulsator is switched, a vacuum is introduced into the nozzle 15, a vacuum is created at the top and bottom of the bypass valve 14. Under the action of its own weight the bypass - the Noah valve 14 is lowered, closing off

nozzle opening 15. Reduced

the vacuum coinciding in size with the vacuum in the spouting chambers falls into the inter-wall chambers. kans, a sucking stroke takes place, which lasts until the pulsator switches, and the atmospheric pressure, falling into the nozzle 15, causes the release of the relief valve 14 and the repetition of the cycle of two-stroke milking

apparatus.
