54) MILKING DEVICE

FIELD: agricultural, household.

A known milking machine containing a pulsator, a collector with a milk chamber, connected to it with an olive branch pipe, communicated by a hose with a milk collecting container, and teat cups fij.

Known milking machine is complicated and inconvenient in operation.

Also known is the milking machine containing a pulsator, a collector with a vertically arranged cylindrical milk chamber, a drain nipple connected to it, communicated by a hose with a milk collecting container, and teat cups, each of which has a body, a nipple tube, an interstitial chamber between them and suckers 2.

This milking machine does not provide the required milking mode.

The purpose of the invention is to improve the mode of milking.

This is achieved by the fact that in the proposed apparatus the bottom of the milk chamber of the collector is installed with the possibility of reciprocating movement in height and is spring-loaded from the outside, the connection point of the drain pipe to the milk chamber of the collector is located on the movement path of its bottom. There are calibrated holes in the upper part of the side wall of the dairy chamber, and ribs on the lower part of the nipple tube. The cavity of the suction cup is connected to the interstitial keiier with calibrated holes.

FIG. 1 shows the milking machine during the suction stroke J in FIG. 2, the same during the rest time.

The milking machine contains milking cups 1, each of which has an interstitial chamber 2 and a podskoskovoy chamber 3, a nipple tube 4, made with corrugations that copy the radii of curvature of the fingers to pa. The wall thickness of the nipple tube 4 is gradually increased in the direction from the corrugated sucker 5 to the bottom. The cavity of the suction cup 5 is communicated by calibrated holes b with the interbed of the teat cup 2.

The milking machine has a collector 7 with a distribution chamber 8 and a vertically arranged cylindrical milk chamber 9, the bottom 10 of which is mounted with the possibility of reciprocating movement along

height and has a clamp-knob 11, serving 1 for forcing the bottom 10 into operation;; In the upper part of the side wall of the chamber 9, calibrated holes 12 are made for constant communication with the atmosphere of the suction. howl chamber 3. teat cup. The milking machine has a membrane pulsator, in which are located chamber 13 of constant vacuum, chamber 14 of overpressure, chamber 15 of alternating pressure (working), chamber 16 of alternating pressure regulating and membrane 17 with valve 18.

In addition, the milking machine has a high vacuum pipe 19 and an over pressure pipe 20. In the lower part of the nipple tube 4, stiffening ribs 21 are made; it is in communication with the chamber 9 by a milk tube 22 having a diameter increased 1.5 times. The bottom 10 is spring-loaded from the outside, and the point of connection of the drain pipe 23 of the collector is located on the path of movement of the bottom 10. The pipe 23 via a hose 24 communicates with the milk: boron tank 25.

Milking machine works as follows.

When turning on the milking machine, the crane of the high vacuum pipe 19 is turned on, then the clamp-handle 11 of the bottom 10 is moved down and the teat cup 1 is suspended from the teats of the udder of the animal. At that time, the chamber 3, cup 1 is maintained at the high vacuum necessary to keep the glass 1 on the udder of the animal. Then, the overpressure pipeline 20 is turned on, the clamp-knob 11 is disconnected, and the bottom 10 is switched to automatic operation.

At the time of the suction stroke, in the working chamber 15 of the pulsator, with the valve 18 closed and the membrane 17 raised, there is an excess pressure of 0.5 atm that spreads into the chamber 8 of the collector 7, from where the air tube into the chamber 2 and the suction cups 5 through the holes of the glasses 1. Through calibrated holes 12 of the chamber 9 of the collector 7, atmospheric pressure is created in the chamber 3 of the cups 1. The bottom 10 with the clamp-knob 11 is in the upper position. blocking the access of the vacuum into the chamber of 3 glasses,

At the same time, the tube 4, under the action of overpressure, gradually compresses the teat of the udder of the animal, by initial compression at the base, from top to bottom, as during manual milking, thereby squeezing out the milk. The milk is transported by gravity into the chamber 9 of the collector 7 and presses with its weight on the bottom 10, while lowering it, the milk chamber.

the collector communicates with the milking bucket, in which the milk is transported under vacuum. When the milk is removed from the chamber 9, the bottom 10 returns to its original position. In this case, the bottom spring 10 is designed for such a weight of milk for its operation, which occupies the volume of chamber 9 at the level of the openings of the milk pipes of the collector 7. At the same time, the suction cups 5 of the cup 1 are compressed, some massage is performed and milk flow is improved. The parameters of the bottom 10 correspond to Hooke's law: P C-S (where P is the weight of milk, C is the coefficient of elasticity of the spring, S is the valve inlet). .

After a certain time, the membrane 17 goes down and opens the valve 18. A vacuum will be created in the working chamber 15, which will come out of chamber 1 and S will be distributed to chamber 8 of collector 7, as well as to chamber 2 and through opening 6 in suction cups 5 of cup 1 In chamber 3 cups 1 there is atmospheric pressure. continuously entering through the openings 12 of the chamber 9 of the collector 7. Due to the pressure difference in the chamber 3 and the chamber 2 of the cup 1, the teat tube is pressed from the nipple and the corrugations are pressed against the walls of the cup 1, and the corrugated suction cups 5 are stretched, providing an udder massage to the teat. Molecular release ceases, and a tact of active rest begins.

Due to the vacuum entering the suction cup opening 6, the cups are retained on the teats of the udder and do not crawl on the teats, and the apparatus is also operated during the sucking and relaxing strokes of the udder massage by compressing and opening the corrugated suction cup. Gradual squeezing of the nipple tube from top to bottom makes it possible to increase the stimulation of milk productivity, to produce the animal more fully.

The constant maintenance of the atmospheric pressure in the milking cup of the teat cup ensures complete milking safety.
