Abstract

The invention relates to agriculture, in particular, to milking machines. The purpose of the invention is to increase the reliability of the milking machine at work and to improve the milking mode. The milking machine contains a pulsator 1, a milking 16 cups 9, a manifold 4 with a flow valve 7. The nipple 10 is fixed in the tip 18 by a latch II having longitudinal ribs and a cylindrical wall. The elastic tube 8 of the flow valve 7 is provided with longitudinal grooves serving to throttle the vacuum with the flow valve closed 7. The lower part of the sleeve of the teat cup 9 is equipped with tide 14. Tide 14 has through channels 15 that connect the interstitial chamber 16 and chamber 17 of the tip 18 the teat cup 9. During the rest stroke, the flexible tube 8 of the winding valve 7 closes, however, thanks to the longitudinal channels, vacuum is throttled into the teat cup 9 and securely retained on the udder nipple. 2 h. p. f-ly, (L 3 il. 1chE with SA :)

Description

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

The purpose of the invention is to increase the reliability of the milking machine at work and improve the milking mode.

FIG. 1 shows the scheme of the milking machine; in fig. 2 - section aa and pa of fig. one; in fig. 3 - section BB on fi1-. one.

The milking machine contains a pulsator 1 with a valve 2 and a membrane 3, a collector 4 with a milk chamber 5 and a distribution chamber 6, a purge valve 7 with an elastic tube 8, milking cups 9 with a nipple stocking 10, a lock And the bottom of the nipple stocking 10, made in as a rigid tube, the constricted part of which is provided with ribs 12 and a second wall 13, in the lower part of the sleeve of the cup 9 there is an annular tide 14 with diametrically arranged channels 15, which communicate the interstitial chamber 16 and the chamber 17 of the tip 18 of the teat Cup 9 to each other .

The elastic tube 8 of the straight valve 7 has a pre-flattened shape and in its flattened part there are semicircular diametrically arranged longitudinal grooves 19. The milk milk chamber 5 of the collector is connected to the suction chambers 21 of the milking stacks 9 with the suction chamber 9. The winding valve 7 is in communication with the distribution chamber 6 of the collector 4.

The milking machine works in the following way.

In the suction stroke, with the valve 2 open, the nulsator 1 enters the distribution chamber 6 of the alternating vacuum of the collector 4, from where it passes through the channels 15 into the interstitial chambers 16 and the chambers 17 of the tips 18 of teat cups 9. At the same time, the vacuum enters the interstitial cavity 22 of the flow valve 7 of the collector 4, as well as of the milk duct (not shown) through the open flow valve 7, the milk chamber 5 of the collector 4, the hose 20 and the retainer 11 of the lower part of the nipple stocking into the nodoscale chamber 21 of the teat Cup 9. Under the action ofvacuum, the milk is sucked off and enters through the hose 19 into the milk chamber 5 of the collector 4 and further into the milk conduit.

When the valve 2 of the pulsator I is closed, atmospheric pressure flows into the distribution chamber 6 of variable vacuum collector 4, from where, through channels 15,

it is placed in the inter-wall chambers 16 and the chambers 17 of the tips 18 of the teat cups 9 and then through the slit formed by the double wall 13 of the narrowed part of the latch 11 into the nodoskoskie chambers 21 of the teat cups 9.

There is a tact of rest. Since the atmospheric pressure is supplied from the outside, the milk chamber 5 of the collector 4 is supplied, the milk from the spraying chamber 21 and the hoses 20 is quickly transported to the milk chamber 5 of the collector 4. At the same time, the atmospheric pressure from the distribution chamber 6 of the non-intermittent vacuum of the collector 4 Bore valve 7.

Under the action of atmospheric pressure, the elastic tube 8 is compressed. The diametrically opposed surfaces of the nipple tube 8 are closed, with this. Diametrically located semicircular grooves 18 are closed, forming a 1.5 mm diameter hole in the cross section through which vacuum cups 9 are fed to the suction boxes 21, which ensures that the milking cups 9 are held on the teats udder After switching the valve 2 of the pulsator 1, the sucking stroke begins again and the nickel is repeated.

Claims (3)

The invention relates to agriculture, in particular to milking apparatuses. The purpose of the invention is to increase the reliability of the milking machine at work and to improve the milking mode. FIG. 1 shows the scheme of the milking machine; in fig. 2 - section aa and pa of fig. one; in fig. 3 - section BB on fi1-. 1. The milking machine contains a pulsator 1 with a valve 2 and a membrane 3, a collector 4 with a milk chamber 5 and a distribution chamber 6, a rotary valve 7 with an elastic tube 8, milking cups 9 with a nipple stocking 10, a lock And the lower part of the nipple stocking 10, made in the form of a rigid tube, the constricted part of which is provided with ribs 12 and a second wall 13, in the lower part of the sleeve of the cup 9 there is an annular tide 14 with diametrically arranged channels 15, which communicate the interstitial chamber 16 and the chamber 17 of the tip 18 of the teat Cup 9 between the assembly d. The elastic tube 8 of the straight valve 7 has a pre-flattened shape and in its flattened part there are semicircular diametrically arranged longitudinal grooves 19. The milk chamber 5 of the collector is connected to the spouting chambers 21 of the milking stacks of the collector 5. valve 7 communicates with the distribution chamber 6 of the manifold 4. The milking machine operates as follows. In the suction stroke, the vacuum, with the valve 2 open, the nullator 1 enters the distribution chamber 6 of the variable vacuum of the collector 4, from where it spreads through the channels 15 to the interwall chambers 16 and the chamber 17 of the tips 18 of teat cups 9. At the same time, the vacuum enters the interwall cavity 22 winding valve 7 of the collector 4, as well as nz of the milk line (not shown) through the open ram valve 7, the milk chamber 5 of the collector 4, the hose 20 and the retainer 11 of the lower part of the nipple stocking into the nodoscale chamber 21 of the milking cup 9. Under the action of Akuma milk is sucked off and enters through the hose 19 into the milk chamber 5 of the collector 4 and further into the milk conduit. When the valve 2 of the pulsator I is closed, atmospheric pressure enters the distribution chamber 6 of variable vacuum of the collector 4, from where it spreads through channels 15 to interwall chambers 16 and kammer 17 tips of 18 teat cups 9 and further through the slit formed by the double wall 13 of the narrowed part of the retainer 11, into the nodsoskovye chambers 21 of the teat cups 9. A tact of rest begins. Since the atmospheric pressure is supplied from the outside, the milk chamber 5 of the collector 4 is supplied, the milk from the spraying chamber 21 and the hoses 20 is quickly transported to the milk chamber 5 of the collector 4. At the same time, the atmospheric pressure from the distribution chamber 6 of the non-intermittent vacuum of the collector 4 valve valve 7. Under the action of atmospheric pressure, the elastic tube 8 is compressed. The diametrically opposed surfaces of the nipple tube 8 are closed, with this. Diametrically located semicircular grooves 18 are closed, forming a 1.5 mm diameter hole in the cross section through which vacuum cups 9 are fed to the suction boxes 21, which ensures that the milking cups 9 are held on the teats udder After switching the valve 2 of the pulsator 1, the sucking stroke begins again and the nickel is repeated. Claim 1. Milking machine, containing a pulsator, teat cups with a nipple stocking and its funnel-shaped lock, in a handpiece connected to the milk tube, a collector with a flow valve, characterized in that, in order to increase its reliability and improve the mode The longitudinal ribs on which there is a cylindrical wall are provided on the constricted part of the retainer, and the milk tube is provided with a pipe in which the wall is coaxially mounted. 2. The apparatus of claim 1, characterized in that the flexible tube of the non-perforated valve B of the middle part of the valve B is made flattened with longitudinal, diametrically disposed, semicircular in cross section grooves. 3.
