(54) MILKING MACHINE

I

The invention relates to the field of sella; households, in particular for milking machines.

Known milking machine, including a collector and a pneumatic pulsator, connected to teat cups, having interwall and ring massage chambers and suckers 1.

However, the known milking machine does not provide the necessary udder massage during milking.

The purpose of the invention is to improve the udder massage during milking.

This is achieved by the fact that the milking machine is equipped with an additional pneumatic pulsator, which is connected to the massage chambers, and each suction cup is formed by the walls of the massage and inter-wall chambers facing each other.

FIG. 1 is a schematic representation of a milking apparatus; in fig. 2 - teat cup of this apparatus; in fig. 3 - section A-A of FIG. 2

The milking machine consists of the pulsator 1, the collector 2, the teat cups 3 and 4, respectively, for the front and rear

udder share. The pulsator contains valve mechanisms (blocks) 5 and 6, separated by a partition 7 of the housing 8. Under the membranes 9 of the valve blocks, there is a common control chamber 10 of the pulsator. Inside the pulsator, there are chambers of constant vacuum 11, alternating pressure 12, 13, and constant overpressure 14.

The apparatus collector has a housing 15 with nozzles 16, above which is mounted an additional pneumatic pulsator 17 for driving massage chambers of teat cups for the front and rear udder lobes. The pulsator 17 contains upper 18 and lower 19 valves of the membrane 20, alternating pressure chambers 21 and 22 connected by hoses 23 and 24 to chambers 12 and 13 of the pulsator 1, constant atmospheric pressure chambers 25, alternating pressure chambers 26 and 27, and constant pressure chamber 28 overpressure connected by hose 29 to a source of overpressure milking

installation (not shown). The milk chamber 30 of the collector is connected by the hose 31 to the milk line of the installation, and the nozzles 32 are connected to the spouting chambers 33 milking cups. Valves 34 and 35 are installed in the collector. The milking cup has a body 36, a milk cup 37, a nipple rubber 38 and a massage cushion 39 with an elastic insert 40. Each glass contains three chambers: a spraying 33, an interwall 41 and a ring massage 42. The massage chambers are connected to chambers 26 and 27 of the pulsator 17 with the help of nozzles 43 and 44. Between the walls of the massage 42 and the wall chambers 41 arranged to each other are suckers 45, for which the lower part 46 of the elastic insert 40 of the massage is made in the form of a washer with a nipple opening. The elastic massager insert 40 is made concave in the shape of the lower part of the udder over the nipple, and the massage chamber 42 can be divided into two parts connected by an opening 48 by means of the partition 47. The partition 47 can be fixed in the eyes of the massage casing 49. To enhance the massaging effect of the teat rubber of the teat cups on the teats of the udder, it is made in the shape of a truncated cone, cut off by two planes touching opposite points of the circumference of the lower base of the cone, and the line of their intersection is the diameter of the upper base of this cone. In the upper part of the nipple, the rubber smoothly passes into the sealing part 50. The pulsator of the apparatus is connected to the vacuum wire with an upward vacuum h and the overpressure pipeline bi, and the collector to the milk line with a reduced vacuum h. To supply a vacuum into the spout chambers, the manifold valve 34 is opened. The device has two cycles - vyzhi.mani and suction and works in pairwise mode with different ratios of cycles in the glasses for before, them and the rear parts of the udder. The drive of the nipple rubber and the elastic inserts of the massagers can be carried out in antiphases. When the apparatus is operating under vacuum, the membrane 9 of the pulsator 1 first rises upward, but the nodes and valve blocks 5 and 6 rise up. Into the interstitial chambers of the teat cups 3 for the front parts of the udder, vacuum h flows from chamber 13, and the interstitial chambers of glasses 4 for the rear lobes receive excess pressure H from chamber 12. At the same time, vacuum collector also enters chamber 21 and vacuum chamber 22 - overpressure, these chambers at the same time serve as control chambers of the pulsator 17 of the massager drive. Under the action of vacuum, the valve 19 is closed, and the valve 18 is opened, and overpressure air is forced into the massage chamber for the front udder parts. Therefore, in cups 3 for the front udder, the teat rubber is stretched to the walls of the body, milk is sucked into the nipple cavity, and the elastic inserts of the massage chambers squeeze the lower part of the udder over the front nipples, which provides an intensive massage of this part of the udder and eliminates the sliding of the glasses on the nipples. At this moment, under the action of overpressure in chamber 22, the upper valve of the pulsator 17 is closed and the lower valve is opened. In the massage chambers 42 teat cups for the rear parts of the udder, atmospheric pressure will be established from chamber 25, the massage of the udder above the rear glasses will stop and the glasses will raise a little, squeeze nipples using nipple rubber, squeezing out the milk. Thus, at this point in the operation of the apparatus in glasses for the front parts of the udder, a suction stroke of the milk occurs with a simultaneous massage of the lower part of the udder, and in glasses for the rear lobes - a nipple squeeze milk stroke - without massaging the lower part of the udder over the nipples. The next moment, the pulsator I supplies the interstitial chambers of milking cups 3 and the control chamber 21 of the pulsator 17 of the actuator. The massage cages of the overpressure air, and the interstitial chambers of the milking cups 4 and the chambers 25 - the pulsator 17 - vacuum. The valves 18 and 19 of this pulsator are switched. In the massage chambers of the teat cups 3 for the front parts of the udder, atmospheric pressure will be established, and the teat rubber, by gradually squeezing the nipple from the base to the top, will ensure that milk is squeezed out of it. Overpressure air enters the massage chambers of the teat cups 4 for the rear parts of the udder. Consequently, at this moment in the glasses 3 for the front parts of the udder the vyzhimani tact occurs without massaging the lower part of the udder, and in the glasses 4 for the rear parts of the udder - a suction stroke with simultaneous massaging the bottom part of the udder. Further, the processes are repeated. The nipples are securely fixed to the nipples by the suction cups 45. Thanks to the improved udder massage during the milking process, intensive stimuli are exercised. Claims The milking machine, including a collector and a pneumatic pulsator, are connected to teat cups having interwall and ring massage chambers and suckers, characterized in that in order to improve the udder massage during the milking process, it is equipped with an additional pneumatic pulsator that is connected to the massage chambers , and each sucker is formed facing each other. 2 friend walls massage and interwall cameras.
