Description

The utility model relates to agriculture, in particular to the means of mechanization of milking cows.

Known milking machine for pairing milking the nipples of the udder of a cow, containing two-chamber milking cups, a pulse collector and hoses [1].

A disadvantage of the known milking machine is the frequent fall of the teat cups from the teats of the udder due to the large weight of the pulsator.

Also known is a two-stroke milking machine for pairing milking the nipples of the udder, containing two-chamber milking cups, a pulsator of pairwise action, a collector and hoses [2].

The disadvantage of the next milking machine is the crawl of the teat cups on the nipples and, therefore, diseases of the cows with mastitis.

The prototype of the invention is a two-stroke pairing milking machine, containing two-chamber milking cups, a pulsator, milk-vacuum hoses and a collector with a milk collection chamber, variable vacuum chambers and with a horizontal hollow cylinder with a piston placed in it with the possibility of movement in the hollow cylinder within a limited dampers mounted on the inner end walls of the hollow cylinder, while on each side of the piston two mutually isolated chambers are formed, each of which si communicated with chambers of variable vacuum of the collector and with interwall chambers of milking cups working in opposite cycles [3].

The disadvantage of the prototype is the inability to determine the end of milking and the moment of disconnection of the milking machine.

The objective of the proposed utility model is to eliminate these disadvantages.

The technical result is an increase in the operational reliability of the milking machine, the purity of milk delivery, the ability to determine the end of milking and the moment the milking machine is turned off.

The specified technical result is achieved by the fact that in a two-stroke pairing milking machine containing two-chamber milking cups, a pulsator, milk-vacuum hoses and a collector with a milk collection chamber, variable vacuum chambers and a horizontal hollow cylinder with a piston placed in it with the possibility of movement within limited dampers mounted on the inner end walls of the hollow cylinder, while chambers are formed on both sides of the piston, each of which communicates with cameras of variable of the collector’s reservoir, according to the invention, the hollow cylinder placed in the housing is made in the form of a coil with a winding around it connected to an electronic unit located on the top of the manifold distributor, while the piston is made in the cylinder in the form of a permanent magnet, and an electrode electrode is placed in the collector’s milk collecting chamber milk flow indicator sensor connected to the electronic unit.

The push-pull milking machine of pairwise milking is illustrated by the schemes:

FIG. 1 is a diagram of a longitudinal section of the proposed milking machine;

FIG. 2 is a collector diagram of a milking machine with an electrode sensor.

A two-stroke pairing milking machine (Fig. 1, 2), contains two-chamber milking cups 1 and 2, a pulsator 3, milk-vacuum hoses 4 and 5, a collector 6 with a milk collection chamber 7, chambers 8 and 9 of variable vacuum, a horizontal hollow cylinder 10 with a piston 11 placed therein, with the possibility of movement within the limits limited by dampers 12, mounted on the inner end walls of the hollow cylinder 10, with chambers 13 and 14 formed on both sides of the piston 11, each of which is connected to chambers 8 and 9 of variable vacuum collector 6. P The hollow cylinder 10 located in the housing 15 is made in the form of a coil 16 with a winding around it connected to an electronic unit 17 located on the top of the manifold distributor 6. In this case, the piston 11 in the cylinder is made in the form of a permanent magnet, and in the milk collection chamber 7 of the collector 6 placed the electrode sensor 18 of the milk flow indicator connected to the electronic unit 17.

The milking machine operates as follows. After connecting the milking machine to a vacuum source, the operator puts the milking cups 1 and 2 on the teats of the udder of the cow. Moreover, the horizontal hollow cylinder 10 of the manifold 6 should be located perpendicular to the longitudinal axis of the animal. During operation of the milking machine, the pulsator of pairwise action 3 delivers vacuum simultaneously to the chamber 8 of the variable vacuum of the collector, and air to the chamber 9 of the variable vacuum. The vacuum from the chamber 8 of an alternating vacuum through the pipe 21 enters the interstitial chamber 19 of the milking cup 1, in this fraction of the udder there is a sucking stroke. At the same time, air from the chamber 9 of an alternating vacuum is supplied through the nozzle 22 to the inter-wall chamber 20 of the milking cup 2, where a compression stroke takes place. Also at the same time, the vacuum through the nozzle 21 enters the chamber 13, and the air through the nozzle 22 into the chamber 14 of the horizontal hollow cylinder 10. There is a pressure drop, under the influence of which the piston 11 made in the form of a permanent magnet moves to the leftmost position (Fig. 2 ) In this case, the elastic damper 12 softens the impact of the piston 11 against the end wall of the horizontal hollow cylinder 10. From the movement of the piston 11, an electric current arises in the coil 16, as well as a change in the position of the center of mass of the collector 6, which prevents the milking cups 1 from crawling onto the udder nipples. And under the milking cups 2, the value of gravity decreases, which contributes to the reliable retention of the milking cups 2 on the nipples of the udder in the compression stroke. When switching the operation of the pulsator 3 pairwise action is the opposite replacement of the clock. In milking cup 2, a sucking stroke occurs, and in milking cup 1, a compression stroke occurs. This changes the direction of the pressure difference acting on the piston 11 in the horizontal hollow cylinder 8. Air enters the chamber 8, and the vacuum enters the chamber 9, which leads to the displacement of the piston 11 to the extreme right position and, accordingly, to the induction of electric current in the 16 v coil in the opposite direction and to a change in the position of the center of mass in the collector 6 (Fig. 2). The process is repeated throughout the entire milking cycle. Induced alternating current in the coil 16, using the electronic unit 17 is rectified and accumulated. The electronic unit 17 receives signals from the electrode sensor 18 of the milk flow indicator located in the collector and, upon termination of the milk flow, gives an audio signal to the operator.

The installation of the electronic unit 17 and the coil 16 with a permanent magnet 11 on the collector of the milking machine will reduce energy costs for the operation of the electrode sensor 18 of the milk flow indicator and eliminates the need for connecting electrical wires from the milk-vacuum valve to the collector.

Using the electronic unit 17 will help the operator determine the end of milking and the moment the milking machine is turned off by equipping the collector with a milk flow indicator.
