Abstract

This invention relates to agriculture. The purpose of the invention is to increase the efficiency of milking. The milking machine contains a pulsator collector 13 with main and additional alternating vacuum chambers, an overpressure chamber 24, teat cups 1 with a primary 4 and an additional 5 spiral elastic tubes. At the same time, both tubes in the lower part have an annular chamber in communication with additional chambers of alternating vacuum of the pulsator collector. The pulse collector is provided with a device for shutting off at least one of the pulsators. Compression of the udder teats in the sucking stroke is carried out alternately with one or the other coiled elastic tube. In the rest stroke, both spiral elastic tubes 4 and 5 release the nipple from impacts. Due to the deformations of the spiral elastic tubes 4 and 5 along the nipples, they are massaged. 3 hp ff, 4 ill.

Description

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

The purpose of the invention is to increase the efficiency of milking.

FIG. 1 shows a schematic of a milking machine during the hedgehog stroke of the main spiral tube; in fig. 2 - the same, during the stroke of the heel of the additional spiral tube; in fig. 3 - the same, during the rest tact in both elastic spiral tubes; in fig. 4 - node I in FIG.

The milking machine contains teat cups 1, each of which includes body 2 with semicircular grooves 3, in which spiral main elastic tube 4 and additional tube 5 are located, each of which in the lower part is equipped with elastic annular chambers 6 and 7 located below the body. 2 and equipped with restrictive rings 8 and 9, suction cups 10, the nipple tube 11, the milk nozzle 12, the pulsoclelector 13.

Pulse collector 13 includes a primary 14 and an additional 15 pulsato-. rya containing membranes 16 and 17, valves 18 and 19, screws 20 and 21, and provided with additional variable pressure chambers 22 and 23 separated from the constant overpressure chamber; pressure 24 partitions 25 and 26 with

holes 27 and 28.

The annular chambers 6 and 7 of the tubes 4 and 5 of the teat cups 1 are connected via hoses 29 and 30 to the aforementioned additional chambers 22 and 23, which by means of the tubes 31 and 32 communicate with the main chambers 33 and 34 of variable pressure, which in turn through pipes 35 and 36 communicate with variable pressure chambers 37 and 38. Partitions 39 with openings 40 are installed between chambers 33, 34 and additional chambers 22,23, respectively.

Membranes 16 and 17 are connected by means of rods 41 and 42 with valves 18 and 19, which are installed with the possibility of blocking openings 27,28,40 and tubes 31, 32 of vacuum pipe 43,

Podsoskov camera 44 teat cups 1 by means of a hose 45.

with a milking bucket 46, which, via reverse tspapan 47, communicates with a constant vacuum pipe 43.

The pulsator collector 13 is provided with a device for switching off the pulsator 15, made in the form of a rod 48 installed in the overpressure chamber 24 and provided with a latch 49 and a control button 50.

Milking machine works as follows.

First, the operator puts the teat cups on the nipples, for which he presses the control button 50 and, by fixing the stem 48, turns off the pulsator 15 (Fig. 1). The vacuum from the vacuum pipe 43 spreads to the additional chamber 23 of variable pressure, through the valve 47 to the milking bucket 46 and further along the head 45 to the outlet 12, to the podoskovoy chamber 44 of the teat cup 1. From the chamber 23 the vacuum through the hose 30 spreads to the bottom an annular chamber 7 and further into the cavity of the elastic tube 5, which contracts to the walls of the body 2 of the cup 1.

After putting on the teat cups, the operator lowers the control button 50. In the rest stroke, the position of the valve 19 of the pulsator 15 is similar to the position of the latter when the mildew cups are put on. At the same time, the valve 18 of the pulsator 14 is in the lower position and closes the opening 27 of the overpressure chamber 24 and the tube 31 connecting the main 33, and the additional 22 of the alternating pressure chamber. At the same time, the vacuum from the conduit 43 extends into the variable pressure chamber 22, from there along the hose, 29 into the annular chamber 7 and further into the cavity of the elastic tube 5, which contracts to the walls of the teat cup 2. Both elastic tubes 4 and 5 are reduced by the action of vacuum, freeing the nipple from exposure, and an active rest tact occurs. Due to the vacuum under the nipples, equal to 40 ... 42 kPa, the teat cups reliably hold on to the nipples.

After the rest tact, there comes a tact of squeezing milk from the teats of the udder of the main 4 or an additional 5 flexible tube

. In the tact of squeezing milk with the main elastic tube 4 valve 18 bullets 5:)

The sator 14 1 is in the upper 1 position and intercepts the opening 40 of the variable pressure chamber 33 and the pipe 43. At the same time, the overpressure from the chamber 24 through the open opening 27 spreads to the variable pressure chamber 22 and further along ishang 29 to the collar chamber 6 and The cavity of the elastic tube 4, which expands in a spiral, squeezes the nipple, squeezing the milk out of it into the suction chamber 44 of the cup, which through the nozzle 12 and the yangang 45 enters the milking bucket 46.15

At this time, the valve 19 of the pulsator 15 closes the additional chamber 23 from the overpressure chamber 24, as well as the tube 32, while the vacuum from the pipe 43 spreads 20 into the chamber 23 and then through the hose 30 into the annular chamber 7 and the elastic tube 5 which does not affect the udder nipple. .. 25

In the milk extraction stroke with an additional elastic tube 5, the pulsator valve 19 is in the lower position and closes the opening 40 of the alternating pressure chamber 34 and the pipeline 30. 43 At the same time, the excess pressure from the chamber 24 through the open opening 28 spreads into the chamber 23 and further along the hose 30 - into the annular chamber 7 and into the cavity of the elastic tube 35 .5, which spirally spirals, squeezes the nipple from top to bottom, squeezing the milk out of it into the suction chamber 44 of the cup 1, which passes 40 through the nozzle 12 and pshang 45 Ved ro 46.

At the same time, the valve 18 of the pulsator 14 closes the additional chamber 22 from the overpressure chamber 24 and the tube 31, while 45 the vacuum from the pipe 43 spreads in the chamber 22 and then through the hose 29 into the annular chamber 6 and the elastic tube 4, which frees the udder nipple from the effects.50

When milking, the teat tubes are then stretched, then shortened in the longitudinal direction due to the restriction of the variable expansion of the facial cavities 6 and 7 with restrictive rings 8 55 9, which provides nipple massage to stimulate milk flow.

To remove the teat cups, the opeator presses the 50 release button.

and, as, CH1-gmaya teat cups.

Adjusting the ratio of the duration of the compression cycles and the distance in the main 4 and an additional 5 elastic tubes of the teat cup are carried out with the adjusting screws: - 2 and 21 pulsators 14 and 15. At the same time, the compression and rest strokes in one elastic tube lag behind one stroke similar strokes in another elastic tube.

The transition from the compression stroke to the drain stroke in the main 4 and the additional 5 elastic tube when the milking machine is operating is essentially smoothly due to the synchronous operation of the pulsators 14 and 15. In the transition to the rest stroke in one elastic tube, the latter is quickly compressed by vacuum under the action of the vacuum , and when moving to the compression stroke, the udder nipple is squeezed smoothly over the screw surface, which provides nipple massage and stimulation of the lactation
