Description

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

A device for milking cows, containing a membrane pulsator, a collector, two-chamber milking glasses 1J, is known.

A device for milking cows is known, comprising teat cups having a sleeve and a nipple tube disposed therein with longitudinal ribs dividing the inter-wall chamber into two parts with nozzles, one of which is connected by means of an air distribution chamber of the collector with a pulsator 2.

Known devices for milking cows do not provide the necessary milking mode.

The purpose of the invention is to simplify the operation of the device for milking cows and increase the intensity of milking.

The goal is achieved by the fact that in a milking machine for cows containing each teat cups, having a sleeve, a nipple tube located in it with longitudinal ribs dividing the interstitial chamber into two parts, the first of which is connected by means of an air distribution chamber of the collector with a pulsator, diametrically located sections the walls of the nipple tube near the suction cup are made curved in the longitudinal direction, and the lower part of the wall of the sleeve has an internal annular thickening ..

The manifold has an additional air distribution chamber connected to the pulsator for paired milking and to the second part of the middle chamber.

The hole of the inner annular thickening of each sleeve and located; In it, a part of the nipple tube is identical in shape.

FIG. 1 schematically shows a device for milking cows; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a sectional view BE in FIG. one.

The device for milking cows contains a membrane pulsator I paired milking, having chambers 2 and 3 of variable pressure, a manifold 4 with a milk chamber 5, a main air distribution chamber 6 and an additional air distribution chamber 7, milking cups 8 containing a sleeve 9 with inner shell a thickening 10, with located in the same vertical and horizontal plane of the nozzle 11 and diametrical longitudinal, made along the entire length of the sleeve protrusions 12, forming a groove 13, having in the popper sechsiii-screw trapezoidal shape, nipple tube 14 with longitudinal trapetsievid GOVERNMENTAL in cross section the ribs 15, the viewing cone 16 mounted directly in gil.ze teatcup Soskova tube 14 has a variable Uwe

the downward thickness of the wall and its ribs 15 are installed in the grooves 13.

8 of its upper part, the nipple tube has convex cavities 17 that replicate the upper

5 oral cavity calf.

Diametrically located wall sections near the nipple tube near the suction cup are curved in the longitudinal direction. At this point, the nipple tube can be made with diametrically located convex sections.

The interstitial chamber of the teat cup 8 with the ribs 15 of the teat tube is divided into two parts 18 and 19, which are slots. 20 and 21 are in communication with the additional main chamber of the collector 4, which, in turn, are in communication with the chambers 2 and 3 of the alternating pressure of the pulsator 1.

The diameter of the hole thickening 10 sleeves

9 is made equal to the distance between its protrusions 12, and the height of the thickening 10 is equal to

0 a part of the viewing cone 16. The milk chamber of the collector 5 is connected to the spouting chambers 22 of the teat grinder, the glasses and the milk conduit (not shown). The aperture of the annular thickening and a part of the nipple tube located in it are made equally in shape.

The milking device operates as follows.

With the chamber open, 3 pulsators 1

0, the vacuum from the chamber 3 spreads to the chamber 6 of the collector 4 and further to the part 19 of the interlayer chamber of the teat cup 8. Since there is a vacuum in the spouting chamber 22, the nipple tube from the side of the part 19 of the thick-walled chamber will be straightened.

At the same time, the atmospheric pressure from the chamber 2 of the pulsator 1 spreads into the chamber 7 of the collector 4 and further along slope 20 into the part 18 of the inter-wall chamber of the teat cup 8.

 At the same time, under the action of the vacuum in the right-hand nursing chamber, the part of the nipple tube 14 is gradually compressed from top to bottom (since the rubber of the tube has a thickness increasing towards the bottom of the glass).

5 When the nipple tube is squeezed, the milk is squeezed out and its suction is simultaneously performed, and this time forces act simultaneously on the nipple - a positive pressure, which squeezes the nipple in the direction from the bottom towards the end and a negative pressure due to the vacuum under the nipple. copied tact suck calf. When sucking off milk, the udder teat is slightly bent due to the convex cavity on the side of interstitial chambers and is clamped somewhat in the same way as

5 is the calf's tongue in the tact of sucking, which causes an increased stimulation of milk flow.

After switching the valves of the pulsator I, the suction process is repeated, only a part of the nipple tube 14 will begin to compress the nipple from top to bottom due to the effect of atmospheric pressure in part 19 of the interstitial chamber of the teat cup 8.

By alternately squeezing the nipple on one side or the other, the teat cups will swing slightly in the horizontal and vertical plane, while the copier will push the udder of the calf, which causes an increase in milk yield.

When the device is working, the milk is continuously sucked away, and in case of incomplete compression of the nipple tube, since the left and right parts of the tube are not a rigid wall, and when compressing one wall, the opposite wall of the glass may be slightly bent.

Continuous suction with some

decreasing it at the moment of switching

pulsator valves allows significantly

increase the intensity of molokovedey,

and consequently, increase the productivity of the milking machine.

Thus, the proposed device makes it possible to increase the intensity of milking due to continuous suction, to improve the stimulation of milk loss due to

alternating action of the left and right convex part of the nipple tube on the nipples. udder while simultaneously squeezing n suction of milk and partial compression of the nipple tube with bending of the nipples and rocking the teat cups, as well as increasing

reliability due to complete tightness of the glass and ensuring proper tension of the nipple tube.
